EXPLORE NOW Tip 2. Be clean air prepared Prep your car to reduce emissions Do your part to reduce emissions on the road by ensuring your car is as fuel-efficient as possible: (1) Service your vehicle regularly. Make sure the particulate filter is emptied regularly if your car uses diesel. Keep your tires properly inflated. Turn off your car when stationary in traffic. Leaving the engine running when the car is not moving can release many harmful pollutants into the air around you, as well as wasting fuel. Pack accordingly If the air quality changes for the worse while you’re on the road and you still want to go outdoors, a snug-fitting, KN95/FFP2 mask can keep you from breathing dust, pollen, and air pollutants. Tip 3. Optimize air quality while in the car Consider cutting down your exposure to air pollution caused by vehicles. Research shows that living and working near roadways can impact your lung function, which can lead to asthma and cardiovascular disease (2). That’s because pollutants like PM2.5, particulate matter measuring 2.5 microns or smaller, are emitted by vehicles through incomplete fuel combustion. PM2.5, carbon monoxide, carbon dioxide, and volatile organic compounds, or VOCs, are all vehicle emissions that can impact health. To lower your exposure to in-car pollution on the road: Keep a buffer between your vehicle and vehicles in front of you, especially diesel trucks. Roll up your windows at stop signs, traffic lights, or in heavy traffic, close your windows, and set your air on recirculate. Travel those forgotten byways – exploring winding back roads mean less traffic, less traffic lights, and oftentimes, better scenery than you’ll find on the highway! Plan to avoid cities during rush hour traffic if you’re going to stay on the highway. Pay attention to which direction smoke is blowing during wildfire season. If possible, route your trip away from the direct path of drifting smoke. Deodorizers or car air fresheners aren’t substitutes for fresh air. They’re pollutant sources, emitters of VOCs. Run a car air purifier. A car air purifier with HyperHEPA Plus particle filtration technology captures commonly found highway pollutants in your car’s interior and prevents them from reaching your breathing space. Tip 4. Sleep safe and sound Air pollutants aren’t limited to the road. Your motel room may appear clean, but the indoor air quality could affect your health and comfort during your overnight stay. Dust, pollen, mold inside walls, and VOCs from cleaning materials can all affect indoor air quality. Dust, pollen, mold inside walls, and VOCs from cleaning materials can all affect indoor air quality in hotels and other lodging. Keep your room’s air quality healthy: If your room’s air quality is poor, open windows and ventilate the room. On high pollen count days or when the outdoor air quality is very poor, keep windows closed. Bring a portable personal air purifier for your room. Setting up a personal air purifier on a bedside table or desk will mean only clean, filtered air reaches the space where you breathe. Tip 5. Enjoy the clean air outdoors Maybe “hitting the road” means not getting in a motor vehicle at all! Instead of driving, consider finding travel alternatives that let you spend more time outdoors – hike, run, camp, walk, or cycle those beautiful vistas already close to home. Big cities like Washington D.C. and New York City have huge parks found on maps of the USA – the National Mall and Central Park respectively – that are fully accessible by public transit; or you can run, walk, or bike to those destinations. If you still want to get away, look for a nearby national park and spend your visit outdoors, outside of your car (3). Check out the park nearest you and see which outdoor activities you can enjoy. Tip 6. Plan longer trips! To deepen your appreciation for a place and lessen your carbon footprint, try planning longer trips and staying in one place. This will prevent excessive travel-related emissions, help you connect with locals, and support the local economy. Alternatively, opt for a nearby domestic stay or staycation. Conclusion Before your next road trip getaway, take control of your air quality. Using these tips will ensure that you and your fellow travelers enjoy the health benefits of clean air, safeguard the environment, and most importantly, truly relax on your road trip.","contentHtml","

Uncover how airborne pathogens spread and what can be done to protect yourself against them.

","Many infectious diseases, from influenza to measles, can travel through the air in microscopic particles known as aerosols. These particles can linger, move through indoor spaces, and be inhaled by others—making them a critical factor in how infections spread. The risks from airborne pathogens are ever-present, and effective strategies are essential to mitigate their impact. How infectious agents become airborne Aerosols are microscopic solid or liquid particles in air or other gases (1). Aerosols range in size from extremely small particles to larger droplets, and many are small enough to remain suspended in the air for extended periods; research has revealed that the smaller sized aerosols can remain suspended in the air for hours, making them a highly efficient vehicle for infectious agents (2). Some of the smallest airborne particles, such as PM2.5, or particulate matter measuring 2.5 micrometers or smaller, can carry viruses, bacteria, or fungi, allowing them to spread beyond close contact and infect individuals who inhale them (3)(4). Pathogens become airborne through coughing, sneezing, and talking; even normal breathing can release infectious aerosols into the environment. Pathogens – including viruses, bacteria, and fungi – become airborne through coughing, sneezing, and talking; even normal breathing can release infectious aerosols into the environment. When an infected person exhales, tiny droplets containing the pathogen evaporate, leaving behind even smaller particles that remain airborne. This infection process is particularly effective in indoor settings, where poor ventilation can trap and concentrate these particles, increasing the risk of transmission (5). Several factors influence how effectively airborne pathogens are spread: Particle size determines how long they stay aloft—smaller particles travel farther and remain suspended longer. Humidity affects their stability; some viruses thrive in dry air, while others persist better in humid conditions (6). Ventilation plays a crucial role. Stagnant air allows aerosols to accumulate, while proper airflow dilutes and removes them. As a group of Montreal-based teachers, scientists, and doctors demonstrated in an unofficial study conducted in 2020, increased carbon dioxide (CO2) accumulated beyond acceptable levels in classrooms through poor ventilation, which may have in turn exposed students and staff to increased risk of exposure to SARS-CoV-2 (7). The duration of exposure also matters; more time spent in contaminated air increases the likelihood of infection. All these factors combined shape the dynamics of airborne transmission. Although airborne transmission is a primary pathway, pathogens can also settle onto surfaces, where they may be transferred through contact—making both air and surface hygiene important in limiting spread. Common airborne pathogens and their risks Among the most well-known airborne threats are viruses that exploit aerosol transmission to infect new individuals. These can include: Influenza: Influenza (or flu) is a contagious respiratory illness. It relies on airborne particles to move between people, often leading to outbreaks in schools, workplaces, and public gatherings (8). Measles: Measles, typically presented by a rash, fever, cough, runny nose, and watery eyes, are extremely contagious. Measles can linger in the air for up to two hours after an infected person leaves a room, infecting those who enter later (9).

Many infectious diseases, from influenza to measles, can travel through the air in microscopic particles known as aerosols. These particles can linger, move through indoor spaces, and be inhaled by others—making them a critical factor in how infections spread.

The risks from airborne pathogens are ever-present, and effective strategies are essential to mitigate their impact.

How infectious agents become airborne

Aerosols are microscopic solid or liquid particles in air or other gases (1). Aerosols range in size from extremely small particles to larger droplets, and many are small enough to remain suspended in the air for extended periods; research has revealed that the smaller sized aerosols can remain suspended in the air for hours, making them a highly efficient vehicle for infectious agents (2).

Some of the smallest airborne particles, such as PM2.5, or particulate matter measuring 2.5 micrometers or smaller, can carry viruses, bacteria, or fungi, allowing them to spread beyond close contact and infect individuals who inhale them (3)(4).

Pathogens become airborne through coughing, sneezing, and talking; even normal breathing can release infectious aerosols into the environment.

Pathogens – including viruses, bacteria, and fungi – become airborne through coughing, sneezing, and talking; even normal breathing can release infectious aerosols into the environment. When an infected person exhales, tiny droplets containing the pathogen evaporate, leaving behind even smaller particles that remain airborne. This infection process is particularly effective in indoor settings, where poor ventilation can trap and concentrate these particles, increasing the risk of transmission (5).

Several factors influence how effectively airborne pathogens are spread:

\nParticle size determines how long they stay aloft—smaller particles travel farther and remain suspended longer.
\nHumidity affects their stability; some viruses thrive in dry air, while others persist better in humid conditions (6).
\nVentilation plays a crucial role. Stagnant air allows aerosols to accumulate, while proper airflow dilutes and removes them. As a group of Montreal-based teachers, scientists, and doctors demonstrated in an unofficial study conducted in 2020, increased carbon dioxide (CO2) accumulated beyond acceptable levels in classrooms through poor ventilation, which may have in turn exposed students and staff to increased risk of exposure to SARS-CoV-2 (7).
\nThe duration of exposure also matters; more time spent in contaminated air increases the likelihood of infection.
\n

All these factors combined shape the dynamics of airborne transmission. Although airborne transmission is a primary pathway, pathogens can also settle onto surfaces, where they may be transferred through contact—making both air and surface hygiene important in limiting spread.

Common airborne pathogens and their risks

Among the most well-known airborne threats are viruses that exploit aerosol transmission to infect new individuals. These can include:

\nInfluenza: Influenza (or flu) is a contagious respiratory illness. It relies on airborne particles to move between people, often leading to outbreaks in schools, workplaces, and public gatherings (8).
\nMeasles: Measles, typically presented by a rash, fever, cough, runny nose, and watery eyes, are extremely contagious. Measles can linger in the air for up to two hours after an infected person leaves a room, infecting those who enter later (9).
\nSARS-CoV-2: This respiratory virus spread COVID-19 globally, with aerosols playing a key role in its transmission (10).
\nChickenpox: Also known as varicella-zoster, chickenpox spreads through contact, through fluids, and is airborne. (11)

Bacteria also pose a significant airborne risk. Mycobacterium tuberculosis, the bacterium responsible for tuberculosis (TB), spreads when infected individuals cough or sneeze, releasing aerosols that can remain infectious for hours (12). Legionella, another bacterial pathogen, thrives in water systems but becomes airborne through contaminated mist or droplets, causing severe pneumonia when inhaled (13).

Learn how HyperHEPA filtration captures ultrafine particles far smaller than the HEPA standard, and why that matters for indoor air quality.

","Indoor air often contains a mix of pollutants that are easy to overlook—dust, pollen, smoke, and microscopic particles from traffic or combustion that can stay suspended in the air we breathe. For people with allergies, asthma, or respiratory sensitivities, reducing those particles indoors can make a noticeable difference in comfort and health. A HyperHEPA air purifier is a filtration-based air purifier designed to capture particles far smaller than the size standard commonly associated with HEPA filtration. In simple terms, it is built for environments where reducing ultrafine airborne particles is especially important. To understand why that matters, it helps to start with what standard HEPA filtration does well—and where higher-performance filtration can go further. What is HEPA filtration? HEPA (high-efficiency particulate air) filters are designed to trap 99.97% of particles as small as 0.3 microns, including dust, pollen, pet dander, and mold spores (1)(2). Originally developed during World War II to contain radioactive particles, HEPA technology has since become the industry standard for air purification. It works by forcing air through a dense mat of fibers, where particles are captured through a combination of interception, impaction, and diffusion. However, HEPA filters have limits. They struggle with ultrafine particles smaller than 0.3 microns, including some viruses and combustion particles. In real-world use, filtration performance also depends on the purifier’s design. If air can bypass the filter because of gaps or poor sealing, some polluted air may circulate without being filtered. In real-world use, those limitations can matter most when the air contains large amounts of ultrafine pollution—such as wildfire smoke, traffic-related combustion particles, or other high-particle events. In those situations, filter performance depends not just on the filter media itself, but also on how well the overall system is sealed. What is HyperHEPA filtration? A HyperHEPA air purifier is an air purifier built with filtration media designed to capture 99.5% of particles down to 0.003 microns—100 times smaller than the 0.3-micron benchmark commonly associated with standard HEPA filtration. That matters because many of the particles people worry about most indoors are extremely small. Ultrafine particles from combustion, traffic pollution, smoke, and some airborne biological material can behave differently from larger dust or pollen particles, staying suspended longer and reaching deeper into the respiratory system. A HyperHEPA air purifier is not a different category of appliance from an air purifier—it is a higher-performance particle filtration approach within an air purifier. In practice, that means the purifier is designed not only around the filter media itself, but also around system sealing and airflow so that filtered air is less likely to bypass the filter. Why ultrafine particles matter Not all airborne particles behave the same way. Larger particles, like visible dust or some pollen, settle more quickly. Ultrafine particles are different: they are so small that they can stay airborne longer and move more easily through indoor spaces. That’s one reason wildfire smoke, traffic emissions, and other combustion-related pollution can be so difficult to manage indoors. Even when the air looks clean, ultrafine particles may still be present. A higher-efficiency filtration system is designed to reduce more of those smaller particles from the air people actually breathe. How is HyperHEPA different from HEPA? When comparing HEPA and HyperHEPA filtration, the main differences come down to particle size performance and system design. Particle size range HEPA filters are designed to capture 99.97% of particles at 0.3 microns. This covers many common indoor particles such as dust, pollen, and mold spores. HyperHEPA filtration is designed to capture 99.5% of particles down to 0.003 microns, extending protection deeper into the ultrafine range. Real-world filtration performance A filter’s effectiveness depends not only on the media, but also on how well the purifier is built. If air bypasses the filter because of gaps or leakage, overall performance drops. HyperHEPA systems are typically designed with tighter sealing so that more of the air moved through the unit is actually filtered rather than escaping around the filter. This difference matters most when indoor air contains a large amount of ultrafine pollution, such as smoke, traffic-related particles, or other combustion byproducts. How to think about air purifier claims Not every air-cleaning technology works in the same way. Some systems are designed to capture pollutants, while others claim to destroy, neutralize, or transform them. That distinction matters. Physical filtration removes particles from circulation by trapping them in filter media. Other technologies may rely on chemical reactions, ionization, or light-based processes, and their effectiveness can vary depending on the pollutant, the room, and how the system is used. When evaluating an air purifier, it helps to ask a few simple questions: What pollutants is it actually designed to address? A good purifier should clearly state whether it is built for particles, gases and odors, or both. Particle filters address things like dust, pollen, smoke, and ultrafine particles; gases and VOCs require sorbent media such as activated carbon. Does it physically remove particles from the air? This is one of the clearest signs of a strong air-cleaning approach. Filtration-based systems trap particles in filter media instead of trying to alter them in the air or push them onto nearby surfaces. Does it rely on added reactive chemistry or generate byproducts? If a purifier uses ozone, ionization, or other reactive processes, it’s worth asking what else may be created along the way. A stronger approach is one that removes pollutants without adding new ones to the room. Is its performance based on clear, testable standards? Look beyond broad marketing claims. CADR can help show how quickly a purifier reduces particles in a room under short-term test conditions, but it does not tell you how performance holds up over time. CCM is useful because it reflects how well a purifier continues performing as filters load with pollutants, giving a better picture of long-term effectiveness. A stronger air purifier claim is usually a simpler one: capture pollutants efficiently, move enough air, and maintain that performance over time. Conclusion A HyperHEPA air purifier is a filtration-based air purifier built to capture extremely small airborne particles—well beyond the particle-size range most people associate with standard HEPA.

See how three pivotal studies changed what the world knows about air pollution—and why that science still matters today.

","Air quality science didn’t advance all at once. It changed through a series of breakthroughs—moments when scientists were able to prove what polluted air was doing to people, where it was coming from, and why it mattered. Some of the most important discoveries began with simple but urgent questions: Why were people getting sick? What was in the air? And could those risks be prevented? Three major turning points reshaped how the world understands air pollution today. Together, they helped transform air quality from an invisible environmental concern into a measurable public health issue—one that continues to guide policy, research, and how communities protect themselves. Scientific breakthroughs only matter if they are shared and acted on. When evidence is delayed, ignored, or dismissed, the consequences can last for years. The history of air quality science shows that progress depends not just on discovery—but on whether societies listen and respond. 1930-1952: Deadly fogs spark modern air quality research In the early 20th century, air pollution was widespread—but poorly understood. That changed when a series of deadly events forced scientists and governments to confront its health impacts. In 1930, a dense industrial fog settled over the Meuse Valley in Belgium. The combination of temperature inversion, trapped emissions, and industrial activity led to 64 deaths. Autopsies found severe respiratory damage, including excess mucus, hemorrhaging and fluid in the lungs. Investigators linked the fatalities to sulfur dioxide and other industrial pollutants, and the findings were published in the Bulletin de l'Académie royale de médecine de Belgique in 1931. It was one of the first connect air pollution with mortality (1). Despite these findings, Belgian authorities laid the blame on chance and local conditions. Ignoring the warnings, other similar, preventable disasters would unfold in later decades in both America and England. Nearly two decades later, a similar disaster struck Donora, Pennsylvania. In October 1948, a temperature inversion trapped emissions from steel and zinc plants, creating a thick smog that killed 20 people and sickened thousands (2). This time, researchers conducted one of the first large-scale epidemiological studies of air pollution, confirming the role of industrial emissions in the disaster. The research team’s findings sparked public outrage and would lay the groundwork for the United States’ Clean Air Act. Then in 1952, London’s Great Smog caused at least 4,000 deaths in just a few days (3). Investigations identified coal burning as the primary source, leading to the United Kingdom’s Clean Air Acts (4). Together, these events and the resulting studies marked a turning point. They showed that polluted air was not just unpleasant—it could be deadly. And they laid the foundation for modern air quality regulation and public health research. 1950s: Dr. Haagen-Smit cracks the LA smog code By the 1940s, Los Angeles was known for its thick, eye-stinging smog—but no one fully understood what was causing it. At the time, many believed smog came primarily from industrial emissions. But Biochemistry professor Dr. Arie Haagen-Smit began a series of experiments in 1948 that revealed smog’s true chemistry. He showed that hydrocarbons and nitrogen dioxide could react in sunlight to form ozone, helping explain the toxic photochemical smog blanketing Los Angeles. His research showed that cars—major emitters of both hydrocarbons and nitrogen dioxide—were central to the city’s air pollution (5). This revelation led to the first vehicle emissions standards (6). Haagen-Smit’s work helped clean the air and transform public perception, forcing policymakers to confront human activity’s role in environmental degradation. 1993: The “Harvard Six Cities” study and the toll of dirty air By the early 1990s, scientists had already established that extreme pollution events could be deadly. The next question was more subtle—and more important for everyday life: what about long-term exposure to lower levels of pollution? In 1993, researchers published what came to be known as the “Harvard Six Cities” study in the New England Journal of Medicine (7)(8). The study followed over 8,000 adults in six U.S. cities for up to 16 years. The participants lived in cities with varying air pollution concentrations. Researchers followed participants over time—including through mailed follow-up cards—to compare survival rates across cities with different pollution levels. The study findings linked long-term exposure to PM2.5—even at low to moderate levels then considered “safe”—to premature death. PM2.5 is particulate matter measuring 2.5 microns in diameter or smaller. The study’s results were confirmed in both a reanalysis of the original study and numerous additional studies. The Harvard Six Cities study would go on to directly influence the WHO’s air quality guidelines (9). The takeaway These breakthroughs changed more than scientific understanding—they changed how societies respond to air pollution. From proving that polluted air could cause immediate harm, to identifying the sources of modern smog, to revealing the long-term risks of fine particle exposure, each discovery helped shape the policies and protections people rely on today. They also offer a reminder: today’s air quality challenges—from microplastics to climate-driven pollution—will require the same combination of curiosity, evidence, and public accountability. Clean air progress begins with research that makes invisible risks visible and actionable. When science is trusted, shared, and turned into policy, it becomes one of the most powerful tools for protecting public health. Observed each year on April 7, World Health Day highlights the importance of science, prevention, and systems that help people live healthier lives. Air quality science is one of the clearest examples of that principle in action—and one of the strongest reminders that healthier futures depend on the evidence we choose to act on.","

Then in 1952, London’s Great Smog caused at least 4,000 deaths in just a few days (3). Investigations identified coal burning as the primary source, leading to the United Kingdom’s Clean Air Acts (4).

Together, these events and the resulting studies marked a turning point. They showed that polluted air was not just unpleasant—it could be deadly. And they laid the foundation for modern air quality regulation and public health research.

1950s: Dr. Haagen-Smit cracks the LA smog code

By the 1940s, Los Angeles was known for its thick, eye-stinging smog—but no one fully understood what was causing it.

At the time, many believed smog came primarily from industrial emissions. But Biochemistry professor Dr. Arie Haagen-Smit began a series of experiments in 1948 that revealed smog’s true chemistry. He showed that hydrocarbons and nitrogen dioxide could react in sunlight to form ozone, helping explain the toxic photochemical smog blanketing Los Angeles. His research showed that cars—major emitters of both hydrocarbons and nitrogen dioxide—were central to the city’s air pollution (5).

This revelation led to the first vehicle emissions standards (6). Haagen-Smit’s work helped clean the air and transform public perception, forcing policymakers to confront human activity’s role in environmental degradation.

1993: The “Harvard Six Cities” study and the toll of dirty air

By the early 1990s, scientists had already established that extreme pollution events could be deadly. The next question was more subtle—and more important for everyday life: what about long-term exposure to lower levels of pollution?

In 1993, researchers published what came to be known as the “Harvard Six Cities” study in the New England Journal of Medicine (7)(8). The study followed over 8,000 adults in six U.S. cities for up to 16 years. The participants lived in cities with varying air pollution concentrations. Researchers followed participants over time—including through mailed follow-up cards—to compare survival rates across cities with different pollution levels.

The study findings linked long-term exposure to PM2.5—even at low to moderate levels then considered “safe”—to premature death. PM2.5 is particulate matter measuring 2.5 microns in diameter or smaller.

The study’s results were confirmed in both a reanalysis of the original study and numerous additional studies. The Harvard Six Cities study would go on to directly influence the WHO’s air quality guidelines (9).

The takeaway

These breakthroughs changed more than scientific understanding—they changed how societies respond to air pollution.

From proving that polluted air could cause immediate harm, to identifying the sources of modern smog, to revealing the long-term risks of fine particle exposure, each discovery helped shape the policies and protections people rely on today.

They also offer a reminder: today’s air quality challenges—from microplastics to climate-driven pollution—will require the same combination of curiosity, evidence, and public accountability.

Clean air progress begins with research that makes invisible risks visible and actionable. When science is trusted, shared, and turned into policy, it becomes one of the most powerful tools for protecting public health.

Observed each year on April 7, World Health Day highlights the importance of science, prevention, and systems that help people live healthier lives. Air quality science is one of the clearest examples of that principle in action—and one of the strongest reminders that healthier futures depend on the evidence we choose to act on.

Microplastics are a growing health concern – so can an air purifier remove these from the air we breathe? Find out more.

","Yes—high-efficiency, filtration-based air purifiers can reduce airborne microplastics. Airborne microplastics are typically fibers and fragments that range from visible specks down to microscopic particles. Some research also discusses nanoplastics (much smaller plastic particles), which may behave more like ultrafine particles in air. A well-designed air purifier that uses mechanical filtration (HEPA/HyperHEPA-class) can capture airborne plastic fibers and fragments as air passes through the filter—reducing how much of this material remains suspended indoors. Because filtration performance depends on the full system (airflow + seal + filter media), the most reliable results come from purifiers built for high particle removal efficiency over time. What are microplastics? Microplastics are small pieces of plastic typically defined as less than 5 millimeters in size. In the air, microplastics often show up as tiny fibers (for example, from synthetic textiles) or irregular fragments (from degraded plastics) (1). You may also see the term nanoplastics, which refers to even smaller plastic particles—often discussed as particles smaller than 1 micrometer. In practical terms: Microplastics are often captured like dust and other similarly sized fibers. Nanoplastics behave more like ultrafine particles, which makes high-performance filtration especially important. Why airborne microplastics are a growing concern Airborne microplastics can be released when common materials shed fibers or wear down—including synthetic clothing, carpets and rugs, upholstered furniture, plastic packaging, and household dust. Indoors, these particles can build up because we spend so much time inside and because fabrics and soft furnishings continuously shed small fibers. Researchers are still mapping the full health picture. What’s clear is that inhalation is one potential exposure pathway, alongside food and water. The main concern with airborne particles—plastic or otherwise—is that smaller particles can be inhaled more deeply into the respiratory system, and they can contribute to irritation or inflammation depending on exposure levels and individual sensitivity (2). A practical takeaway: The same strategies that reduce other indoor particle pollution (dust, PM2.5, smoke) also help reduce airborne microplastic fibers and fragments. How air purifiers capture microplastics Air purifiers reduce airborne microplastics the same way they reduce other particles: by pulling room air through a dense filter that physically traps particles. The most effective approach for occupied spaces is mechanical filtration, not ozone or reactive chemistry. Key factors that determine effectiveness: Filter media (HEPA/HyperHEPA-class): These filters are designed to capture fine particles efficiently. Airborne microplastics are often fibers and fragments that fall well within the range that high-efficiency filters can trap. System design airflow, and sealing: Performance isn’t just the filter—it’s also how much clean air the purifier delivers, how well the housing prevents bypass leakage, and how consistently it performs as filters load over time. Placement and run time: Because microplastics can be continuously shed indoors, filtration works best when the purifier runs consistently, especially in bedrooms and living areas. A note on performance metrics: Many brands highlight CADR, which is mainly a speed metric (how quickly a purifier can reduce particle concentration in a test room). For long-term protection, it also matters how well a purifier holds up as the filter loads. Metrics like Cumulate Clean Mass (CCM) are designed to reflect durability over time—how much pollution a system can remove before performance declines. In practical terms, a purifier that starts strong but loses efficiency quickly won’t reduce exposure as consistently as one built for sustained performance. Limitations and complementary strategies Air filtration can reduce what’s floating in the air—but microplastics can also settle on surfaces or enter the body through other exposure pathways (such as food and water). That’s why the most effective approach is layered: reduce shedding at the source, keep particles from building up, and filter what remains airborne. Practical steps to reduce airborne microplastics at home: Reduce shedding sources (where feasible): Choose natural fibers for bedding and frequently used textiles; wash synthetic clothing with care to reduce fiber shedding. Clean to remove settled dust: Vacuum regularly (ideally with a HEPA-filtered vacuum) and wipe surfaces with a damp cloth so microplastic particles aren’t reintroduced into your breathing space.

Don’t wait for smoke to fill the skies – follow these tips to be ready for crop burning season this year.

","Crop burning is the deliberate burning of agricultural leftovers, such as rice straw or wheat stubble, to clear fields quickly for the next planting cycle. Crop burning smoke can travel hundreds of miles and linger for days or weeks, depending on weather conditions. Millions of tons of crop residue are burned annually, sending smoke into distant cities and neighboring countries (1). Agricultural fire smoke creates a recurring seasonal health problem that disrupts daily life, strains healthcare systems, and deepens the global burden of air pollution. In the weeks leading up to crop burning season, it’s critical to make a plan to avoid exposure to smoke and airborne pollutants. What is crop burning? Crop burning is a fast, low-cost way to clear leftover plant material after harvest. Farmers may burn straw, stalks, or stubble directly in the field, or pile residues and burn them in one place. For many growers, time is critical. There is often only a short window between harvest and the next planting. Burning can remove heavy residue quickly, reduce certain pests or plant diseases, and prepare fields faster than mechanical methods that require extra fuel, labor, and equipment passes. Burns often happen in that narrow window between harvest and planting, which is why smoke shows up seasonally. Weather plays a major role, and wind can carry smoke far beyond the field, while still air can trap it closer to the ground. Burning is efficient, but it comes with trade-offs. Some nutrients in crop residue—especially nitrogen and sulfur—can turn into gases and drift away with the smoke. Others, like phosphorus and potassium, remain in the ash, which can blow away or wash off the field before those nutrients return to the soil (2). The science behind the smoke When crops burn, they release a complex, invisible cocktail of pollutants. When crops burn, they release a complex, invisible cocktail of pollutants. At the forefront is PM2.5, particulate matter measuring 2.5 microns or less in diameter. These microscopic particles are small enough to bypass some of the body’s defenses, reach deep into the lungs, and in some cases enter the bloodstream. PM2.5 can trigger inflammation, worsen asthma, and is linked to long-term risks like lung cancer and heart disease. Crop burning smoke can also release carbon monoxide, nitrogen oxides, and volatile organic compounds (VOCs), all pollutants that can negatively impact human health. Studies have found links between crop burning spikes and rises in hospital admissions for respiratory diseases, including asthma (3). Who is most at risk? When crop burning season arrives, the health burden falls greatest on those individuals who are the most vulnerable. Children, whose lungs are still developing, face heightened risks of asthma and stunted lung growth from prolonged exposure to PM2.5 (4). The elderly, especially those with pre-existing heart or lung conditions, see hospitalizations surge as fine particles deepen inflammation and exacerbate chronic diseases (5). For outdoor workers, including farm workers, there’s no escaping the impact of crop residue smoke. For outdoor workers, including farm workers, there’s no escaping the impact of crop residue smoke. Their livelihoods force them into the thick of the pollution, where every breath increases the risk of severe respiratory distress. People with asthma and other chronic respiratory diseases can be strongly impacted by the smoke. Repeated exposure to PM2.5 from smoke aggravates asthma, decreases lung function, and is linked to premature death (6). In urban populations downwind, particularly in densely packed cities with poor ventilation, smoke settles into a stubborn haze. Low-income communities, often lacking access to air filtration or healthcare, are hit hardest. Where is crop burning most common? Crop residue burning happens in agricultural regions worldwide. It tends to be most prevalent where large harvests are followed by a short turnaround to the next planting, and where residue is difficult to manage quickly with equipment, labor, or storage options. South Asia Burning is widespread after harvests, especially for wheat, rice, and maize stubble. Smoke can drift across borders, affecting parts of Pakistan, northern India, Bangladesh, and Nepal (7). During the post-monsoon burning season, studies estimate crop-residue burning can contribute about 30–34% of surface PM2.5 on average, and about 50–56% during plume events that transport smoke downwind toward major population centers (8). East Asia China has worked to curb crop stubble burning, but enforcement varies and seasonal burning persists—particularly in parts of Northeast China (9). Southeast Asia In mainland Southeast Asia, seasonal haze has been strongly linked to open biomass burning, a category that includes agricultural residue burning along with other burning types. One regional analysis estimated open biomass burning contributed about 57% of PM2.5 concentrations across parts of mainland Southeast Asia during the period studied. In addition to crop residue burning, land clearing practices in countries such as Laos, Thailand, and Indonesia contribute to seasonal haze. Smoke can travel across national borders and affect neighboring countries downwind. Regional coordination has increased, and the Association of Southeast Asian Nations (ASEAN) has pledged to phase out the practice across member states (10) Europe Many European Union member states and the United Kingdom have strong restrictions on open burning. Even so, smoke can still drift in from neighboring countries where enforcement is weaker or where rules differ (11)(12). United States In the United States, agricultural burning occurs in multiple crop systems and has been identified as an understudied health concern for some rural communities, including parts of the Upper Great Plains . In EPA’s 2020 National Emissions Inventory (NEI), agricultural burning is shown as a measurable PM2.5 emissions source, with emissions concentrated in Florida, Washington, Georgia, and Horth Dakota, among others (13). Global and local efforts to curb crop burning The first step in preparing for crop burning season is to eliminate the smoke at its source. If farmers lack access to alternatives to residue burning and enforcement is inconsistent, there can be mitigation challenges. But there are promising solutions that combine top-down policies with grassroots adoption of new technologies. The first step in preparing for crop burning season is to eliminate the smoke at its source. For instance, India provides subsidies for “happy seeders,” machines that plant new crops without burning stubble. Farmers who adopted the technology were able to cut costs on land preparation, irrigation, and fuel use while still maintaining consistent, moderate crop yields (14). China’s strict bans and enforcement via satellite surveillance helped reduce fires in key provinces like Heilongjiang (15). However, controlled fires are starting to make a comeback as some local officials are loosening restrictions. While there are companies and initiatives to pay farmers for stubble use as biofuels or animal feed, greater subsidies may be needed to support farmers due to the high supply and low demand for crop waste. Turning waste into income offers a powerful alternative to the traditional burns. For instance, in Southeast Asia, Thailand and Vietnam are piloting programs to convert rice straw into biofuel or compost, turning waste into revenue (16) (17). If you live downwind of agricultural regions—or you’ve seen seasonal haze before—planning ahead can reduce exposure when smoke returns. How to protect your family and community Stopping the fires at their source is critical. Even so, it’s essential to develop an action plan and know what steps to take before smoke begins to drift into homes and businesses. What governments, communities, and organizations can do Pass legislation strongly limiting crop burning and regularly enforcing those laws. Support local farmers by providing subsidies for no-burn equipment and techniques. Push local, regional, and national officials for stricter enforcement of burning bans. Report violations to local environmental agencies. Help connect farmers with cooperatives that offer affordable rentals of no burn equipment. What individuals can do Before smoke arrives: Set up a simple monitoring routine: check PM2.5 and the Air Quality Index (AQI) regularly so you can spot poor air quality conditions early. Ventilate only when outdoor air is clean. Prep your indoor air plan: identify a “clean room” (usually a bedroom or living room) where you can keep windows closed and run a high-performance air purifier. If you may need to be outdoors during smoky periods, keep a well-fitted pollution mask on hand. When smoke is high: Keep windows and doors closed and avoid bringing smoky air indoors. Reduce indoor pollution sources that add particles to the air (for example: don’t burn candles, limit frying or high-smoke cooking). Move exercise and kids’ playtime indoors until air quality improves. If you must go outside, wear a well-fitted face mask and keep outdoor time as short as possible. Run a high-performance air purifier consistently, especially in your clean room. Track conditions with an air quality monitor and an air quality app so you can adjust quickly as smoke rises or clears. Conclusion Push for stronger legislation and enforcement, or helping farmers adopt smokeless alternatives, there are options for helping get ahead of the annual smoke. This harvest season, take steps to safeguard your health, stand with vulnerable neighbors, and demand systems that prioritize clean air for all.","

However, controlled fires are starting to make a comeback as some local officials are loosening restrictions. While there are companies and initiatives to pay farmers for stubble use as biofuels or animal feed, greater subsidies may be needed to support farmers due to the high supply and low demand for crop waste.

Turning waste into income offers a powerful alternative to the traditional burns. For instance, in Southeast Asia, Thailand and Vietnam are piloting programs to convert rice straw into biofuel or compost, turning waste into revenue (16) (17).

If you live downwind of agricultural regions—or you’ve seen seasonal haze before—planning ahead can reduce exposure when smoke returns.

How to protect your family and community

Stopping the fires at their source is critical. Even so, it’s essential to develop an action plan and know what steps to take before smoke begins to drift into homes and businesses.

What governments, communities, and organizations can do

Pass legislation strongly limiting crop burning and regularly enforcing those laws.
Support local farmers by providing subsidies for no-burn equipment and techniques.
Push local, regional, and national officials for stricter enforcement of burning bans.
Report violations to local environmental agencies.
Help connect farmers with cooperatives that offer affordable rentals of no burn equipment.

What individuals can do

Before smoke arrives:

Set up a simple monitoring routine: check PM2.5 and the Air Quality Index (AQI) regularly so you can spot poor air quality conditions early.
Ventilate only when outdoor air is clean.
Prep your indoor air plan: identify a “clean room” (usually a bedroom or living room) where you can keep windows closed and run a high-performance air purifier.
If you may need to be outdoors during smoky periods, keep a well-fitted pollution mask on hand.

When smoke is high:

Keep windows and doors closed and avoid bringing smoky air indoors.
Reduce indoor pollution sources that add particles to the air (for example: don’t burn candles, limit frying or high-smoke cooking).
Move exercise and kids’ playtime indoors until air quality improves.
If you must go outside, wear a well-fitted face mask and keep outdoor time as short as possible.
Run a high-performance air purifier consistently, especially in your clean room.
Track conditions with an air quality monitor and an air quality app so you can adjust quickly as smoke rises or clears.

Conclusion

Push for stronger legislation and enforcement, or helping farmers adopt smokeless alternatives, there are options for helping get ahead of the annual smoke.

This harvest season, take steps to safeguard your health, stand with vulnerable neighbors, and demand systems that prioritize clean air for all.

Explore 5 practical ways to reduce waste during Ramadan—food, plastics, water, energy, and transportation—and emphasizing the spirit of renewal.

","For roughly a quarter of the world’s population, Ramadan is a month that reshapes daily life — from meals and prayer to family gatherings and community care (1). It’s a deeply meaningful season, and for many, a chance to recommit to living with intention. Because daily routines change so much during Ramadan — what we cook, what we buy, how we gather, and how we travel — it can also be a natural moment to reduce waste and use shared resources more thoughtfully. Ramadan, in brief Ramadan is the ninth month of the Islamic calendar, observed through fasting from dawn to sunset, prayer, and acts of charity. At its heart, it’s about renewal, self-discipline, gratitude, and caring for others — values that naturally support more mindful choices in everyday life. Here are five simple tips to get started. 1. Plan meals to reduce food waste Iftar (the evening meal that breaks the fast) and suhoor (the pre-dawn meal before fasting begins) are meaningful moments, and it’s common to overestimate how much food a household (or a gathering) will actually need. The result isn’t just extra dishes and leftovers. Food waste also represents wasted water, packaging, and energy. Ramadan is a time to pause and reflect on what we truly need — and to treat food as a blessing, not a given. A helpful mindset shift is to plan Ramadan meals the way you might plan for hosting: start with what you know you’ll use, then leave room to adjust. Try planning a few days at a time instead of shopping “for the whole week,” especially early in the month while you’re learning your family’s rhythm. A simple approach that works for many households: Shop with a short list. Buy what you can realistically cook and finish. Cook modestly, then add. It’s easier to make a little more than to undo too much. Give leftovers a purpose. For instance, tonight’s iftar can become tomorrow’s suhoor. If you do end up with extra, consider sharing it intentionally — with neighbors, friends, or anyone who might benefit. It keeps the spirit of generosity intact while preventing waste. 2. Cut single-use plastics at iftars and gatherings Community iftars and mosque nights are some of the most beautiful parts of Ramadan. They can also be where waste quietly piles up: plastic water bottles, cups, plates, and cutlery — often used for minutes and then and can remain in the environment for years. Ramadan is a month of gathering, so it’s an opportunity to gather thoughtfully, with small choices that reduce waste and what we throw away. 3. Conserve water, especially during wudu and in the kitchen Water use often increases during Ramadan: more cooking, more cleaning, more wudu (ritual washing before prayer), more guests. Because the month is busy, it’s easy to use more than necessary without noticing. Ramadan is a reminder that intention can show up in small moments — including how we use everyday resources like water. Instead of treating water conservation like a major lifestyle overhaul, treat it like mindfulness: small, repeated moments of intention. In daily routines, that can look like: Turning off the tap while brushing your teeth Avoiding continuously running water during wudu Washing produce in a bowl instead of under a running faucet If your mosque provides bottled water, another simple step is to finish what you take and dispose of it properly — or bring your own reusable bottle so fewer bottles are left behind at the end of the night. In many regions, water is already a scarce resource. Mindful use is practical and deeply aligned with the month’s emphasis on gratitude. An eco-friendly Ramadan isn’t about perfection. It’s about small choices that add up across households and communities. 4. Use less energy and practice conscious consumption Ramadan evenings often run late. Lights stay on longer. Kitchens stay busy. Families make extra store trips. None of this is “wrong” — it’s simply part of how Ramadan changes the rhythm of life. But the month can also be an invitation to simplify: to reduce what’s unnecessary, keep what’s meaningful, and build habits you’ll want to continue. That’s the heart of reflection — noticing where our routines drift into excess and gently returning to what matters. One way to think about energy and consumption during Ramadan is: reduce the “background” load. The small, forgettable things that add up. A few low-effort shifts: Turn off lights, chargers, and appliances when they’re not in use Swap to energy-efficient bulbs where possible Reduce store trips by planning ahead (one larger trip instead of many small ones) Avoid impulse purchases and overbuying “just in case” And if you want a non-technical “reset” that fits the spirit of the month: swap a bit of screen time for something quieter — reading, reflection, or community time. 5. Rethink transportation and build community habits During Ramadan, trips to the mosque, grocery store, and family gatherings can add up quickly, especially in communities where events run nightly. Transportation is one of those areas where small changes can have a collective impact. Ramadan is about community care, and how we move and how often we drive can be part of that care. If it’s feasible in your area, walking or cycling to prayers can reduce fuel and road use while adding something surprisingly valuable: a calm transition into the evening. When distance or safety makes that unrealistic, community habits can still help: Carpool for taraweeh (special evening prayers during Ramadan) or community events Combine errands into one trip instead of several Keep tires properly inflated to improve fuel efficiency When these habits spread across a neighborhood, they don’t just reduce environmental impact, they also strengthen community connection, which is part of what Ramadan is about. The takeaway Eco-friendly habits don’t have to feel like a separate “project.” They can be part of what Ramadan already teaches: intentional living, moderation, and gratitude. If you choose just one change this month, make it a simple one — and make it consistent. Small actions, repeated across weeks of Ramadan and shared across communities, can carry forward long after Eid.","

For roughly a quarter of the world’s population, Ramadan is a month that reshapes daily life — from meals and prayer to family gatherings and community care (1). It’s a deeply meaningful season, and for many, a chance to recommit to living with intention.

Because daily routines change so much during Ramadan — what we cook, what we buy, how we gather, and how we travel — it can also be a natural moment to reduce waste and use shared resources more thoughtfully.

Ramadan, in brief

Ramadan is the ninth month of the Islamic calendar, observed through fasting from dawn to sunset, prayer, and acts of charity. At its heart, it’s about renewal, self-discipline, gratitude, and caring for others — values that naturally support more mindful choices in everyday life.

Here are five simple tips to get started.

1. Plan meals to reduce food waste

Iftar (the evening meal that breaks the fast) and suhoor (the pre-dawn meal before fasting begins) are meaningful moments, and it’s common to overestimate how much food a household (or a gathering) will actually need. The result isn’t just extra dishes and leftovers. Food waste also represents wasted water, packaging, and energy. Ramadan is a time to pause and reflect on what we truly need — and to treat food as a blessing, not a given.

A helpful mindset shift is to plan Ramadan meals the way you might plan for hosting: start with what you know you’ll use, then leave room to adjust. Try planning a few days at a time instead of shopping “for the whole week,” especially early in the month while you’re learning your family’s rhythm.

A simple approach that works for many households:

Shop with a short list. Buy what you can realistically cook and finish.
Cook modestly, then add. It’s easier to make a little more than to undo too much.
Give leftovers a purpose. For instance, tonight’s iftar can become tomorrow’s suhoor.

If you do end up with extra, consider sharing it intentionally — with neighbors, friends, or anyone who might benefit. It keeps the spirit of generosity intact while preventing waste.

2. Cut single-use plastics at iftars and gatherings

Community iftars and mosque nights are some of the most beautiful parts of Ramadan. They can also be where waste quietly piles up: plastic water bottles, cups, plates, and cutlery — often used for minutes and then and can remain in the environment for years. Ramadan is a month of gathering, so it’s an opportunity to gather thoughtfully, with small choices that reduce waste and what we throw away.

3. Conserve water, especially during wudu and in the kitchen

Water use often increases during Ramadan: more cooking, more cleaning, more wudu (ritual washing before prayer), more guests. Because the month is busy, it’s easy to use more than necessary without noticing. Ramadan is a reminder that intention can show up in small moments — including how we use everyday resources like water.

Avoiding continuously running water during wudu
Washing produce in a bowl instead of under a running faucet

If your mosque provides bottled water, another simple step is to finish what you take and dispose of it properly — or bring your own reusable bottle so fewer bottles are left behind at the end of the night.

In many regions, water is already a scarce resource. Mindful use is practical and deeply aligned with the month’s emphasis on gratitude.

An eco-friendly Ramadan isn’t about perfection. It’s about small choices that add up across households and communities.

4. Use less energy and practice conscious consumption

Ramadan evenings often run late. Lights stay on longer. Kitchens stay busy. Families make extra store trips. None of this is “wrong” — it’s simply part of how Ramadan changes the rhythm of life.

But the month can also be an invitation to simplify: to reduce what’s unnecessary, keep what’s meaningful, and build habits you’ll want to continue. That’s the heart of reflection — noticing where our routines drift into excess and gently returning to what matters.

And if you want a non-technical “reset” that fits the spirit of the month: swap a bit of screen time for something quieter — reading, reflection, or community time.

5. Rethink transportation and build community habits

During Ramadan, trips to the mosque, grocery store, and family gatherings can add up quickly, especially in communities where events run nightly. Transportation is one of those areas where small changes can have a collective impact. Ramadan is about community care, and how we move and how often we drive can be part of that care.

If it’s feasible in your area, walking or cycling to prayers can reduce fuel and road use while adding something surprisingly valuable: a calm transition into the evening. When distance or safety makes that unrealistic, community habits can still help:

Carpool for taraweeh (special evening prayers during Ramadan) or community events
Combine errands into one trip instead of several
Keep tires properly inflated to improve fuel efficiency

When these habits spread across a neighborhood, they don’t just reduce environmental impact, they also strengthen community connection, which is part of what Ramadan is about.

The takeaway

Eco-friendly habits don’t have to feel like a separate “project.” They can be part of what Ramadan already teaches: intentional living, moderation, and gratitude.

If you choose just one change this month, make it a simple one — and make it consistent. Small actions, repeated across weeks of Ramadan and shared across communities, can carry forward long after Eid.

New research highlights how air pollution can quietly disrupt sleep — and treatments that can help restore your sleep.

","We all know air pollution harms the heart, lungs, and brain — but new evidence shows it can also steal our sleep.A comprehensive study out of Johns Hopkins University School of Nursing analyzed data from more than 1.2 million adults across six countries. The results are striking: people exposed to higher levels of air pollution, including fine particulate matter (PM2.5), nitrogen dioxide (NO₂), and carbon dioxide (CO₂), consistently reported shorter or poorer-quality sleep (1).Sleep is foundational to immune function, cognitive performance, and emotional regulation — making air quality a powerful factor in how well we rest.What makes this connection especially important is that sleep isn’t just a nightly routine — it’s a biological reset that pollution can quietly disrupt without us noticing.From early childhood through older adulthood, disrupted sleep compounds health risks — making air quality a quiet but consistent influence on sleep health. The hidden link between air pollution and sleep Sleep is shaped by far more than light, noise, or bedtime habits. The air we breathe—hour after hour, night after night—plays a subtle but powerful role in how deeply we sleep, how often we wake, and how well the body recovers overnight. According to the study, even modest pollution increases were linked with restless nights, insomnia, and shorter sleep duration — more impactful effects than scientists expected. “Air quality – both outdoors and inside the home – is an underrecognized contributor to sleep problems,” said Dr. Junxin Li, lead researcher for the study. “Cleaner air not only safeguards lungs and hearts, it also helps people sleep, supporting cognition, mood, and overall resilience.” These findings point to a broader pattern: air pollution doesn’t just affect sleep in extreme conditions, but subtly influences sleep quality across populations, environments, and everyday exposure levels. Cleaner air…helps people sleep, supporting cognition, mood, and overall resilience.”—Dr. Junxin Li, Johns Hopkins University What the research show The review combined findings from 25 high-quality studies conducted since 2015, covering adults over 45 years old in China, India, the U.S., Germany, and other nations. It was found that cutting average PM2.5 concentrations in half—from the levels typically found on busy city streets down to the World Health Organization (WHO) guideline—could reduce the likelihood of poor sleep by about 10 percent among middle-aged and older adults. In other words, cleaner air could help millions of people gain roughly an extra hour of rest each night. That insight helps explain why sleep disruption shows up not only in polluted cities, but also in everyday indoor spaces where people spend much of their lives. Indoor air matters, too While outdoor air pollution often gets the most attention, indoor air quality plays a critical role in sleep health—especially because people spend nearly a third of their lives asleep indoors. For many adults, nighttime exposure inside the home may represent their longest and most consistent contact with air pollution. Dr. Li’s team found that indoor pollution can be just as harmful — especially for older adults, who often spend most of their time indoors. Only six high-quality studies examined indoor sources, but their conclusions were clear: households using solid fuels such as coal or wood for cooking or heating reported far worse sleep outcomes than those using clean energy. And homes that used ventilation fans or opened windows during cooking saw notable improvements in sleep quality — evidence that even small steps to improve indoor air can matter. Sleep quality isn’t shaped only by what happens during the day, but by the air we’re exposed to night after night—making it important to understand how air pollution disrupts sleep in the first place. How air pollution disrupts sleep quality Air pollution can interfere with sleep quality through inflammation, nervous-system stimulation, and reduced oxygen exchange during the night. Prolonged exposure to even low-level pollutants can interfere with the body’s natural recovery processes.Unlike daytime exposure — which is intermittent — sleep creates a long, uninterrupted window where the body is continuously affected by the air it breathes. That makes nighttime air quality especially influential, even when pollution levels are relatively low.Scientists are still uncovering the mechanisms linking pollution to sleep problems, but several pathways are already well-understood: Inflammation and oxidative stress: Fine particles penetrate deep into the lungs and bloodstream, triggering systemic inflammation that can disturb normal sleep cycles. Nervous-system stimulation: Nitrogen dioxide and other gases can activate stress responses that increase heart rate and restlessness. Reduced oxygen exchange: Elevated CO₂ levels in bedrooms can lower oxygen availability, fragmenting deep sleep and REM phases. Noise and thermal effects: Polluted urban environments often coincide with traffic noise and higher nighttime temperatures — both known sleep disruptors. The outcome? More tossing, turning, and waking — and fewer restorative hours of rest. How clean air supports deeper, more restorative sleep When the air you breathe is free of pollutants, your body can maintain balanced oxygen and carbon-dioxide levels. Your heart rate stays steady, airways remain open, and inflammation decreases. That supports slow-wave (deep) sleep, the stage critical for physical repair and immune recovery. Nights spent in cleaner air environments showed measurable improvements in sleep efficiency and oxygen saturation. In studies of adults with asthma or cardiovascular disease, nights spent in cleaner air environments showed measurable improvements in sleep efficiency and oxygen saturation. Over time, better sleep quality is linked to lower cardiovascular risk, stronger immune response, improved memory, and better mental health — amplifying the health benefits of cleaner air beyond the bedroom. Indoor air quality while you sleep During sleep, we spend several uninterrupted hours breathing the air in a single enclosed space. Unlike daytime hours—when doors open, windows are used, and air is constantly exchanged—bedrooms often become more sealed at night, allowing pollutants to accumulate. Research shows that indoor air pollution can exceed outdoor levels by two to five times, especially overnight when ventilation is reduced. For people living near busy roads, dense urban corridors, or industrial areas, nighttime exposure may remain elevated—even when outdoor air quality appears good during the day. The encouraging news is that many of the most common bedroom pollutants are well understood—and highly controllable once identified. Understanding where these pollutants come from makes it easier to reduce exposure and create a sleep environment that supports the body’s natural overnight recovery. Common bedroom pollutants include: PM2.5 and ultrafine particles — from traffic exhaust, cooking, and candles.Impact: Can increase inflammation and interfere with deep, restorative sleep. Nitrogen dioxide (NO₂) — from gas stoves and heaters.Impact: May trigger airway irritation, wheezing, and nighttime restlessness. Volatile organic compounds (VOCs) — from cleaning products, paints, and new furniture.Impact: Can contribute to headaches, dizziness, and difficulty falling asleep. Carbon dioxide (CO₂) — from human exhalation in sealed rooms.Impact: Higher levels are associated with drowsiness and fragmented sleep. With the right combination of ventilation, monitoring, and filtration, these exposures can be significantly reduced—helping create a calmer, more supportive environment for sleep. Clean air solutions for better rest Improving sleep through cleaner air isn’t about perfection — it’s about reducing exposure where it matters most, during the hours your body is working hardest to recover. Sleep is a prolonged, uninterrupted activity, so small improvements in air quality can have an outsized impact overnight. Protecting sleep quality requires a layered approach to improving indoor air quality: Monitor indoor and outdoor air quality: Tracking conditions with an air quality monitor helps identify patterns—such as elevated PM2.5 or CO₂ levels at night—and informs when ventilation or filtration is most beneficial. Real-time data makes it easier to respond proactively rather than guessing. Downloading an air quality app can also provide outdoor air quality in the palm of your hand. Ventilate strategically: When outdoor air quality is good, opening windows or using extractor fans during cooking and cleaning helps prevent pollutants from building up indoors. Even brief ventilation before bedtime can lower overnight exposure. Use high-performance filtration where you sleep: Because the smallest particles are most likely to penetrate deep into the lungs and disrupt sleep, filtration that captures ultrafine particles is especially important in bedrooms. Air purifiers with HyperHEPA filtration are designed to remove particles far smaller than the limits of standard HEPA. Together, these steps help create an indoor environment that works with the body’s natural sleep processes, making cleaner air an enabler of deeper, more restorative rest. Studies suggest that improvements in bedroom air quality can influence sleep quality within days or weeks, not just over months or years. Conclusion Sleep is one of the body’s most powerful recovery tools — and the air you breathe plays a meaningful role in how well it works. By reducing exposure to particulate pollution indoors and out, you can support healthier sleep, protect your lungs, heart, and brain, and give your body the restorative rest it needs—especially over the long term.","

We all know air pollution harms the heart, lungs, and brain — but new evidence shows it can also steal our sleep.

The results are striking: people exposed to higher levels of air pollution, including fine particulate matter (PM2.5), nitrogen dioxide (NO₂), and carbon dioxide (CO₂), consistently reported shorter or poorer-quality sleep (1).

Sleep is foundational to immune function, cognitive performance, and emotional regulation — making air quality a powerful factor in how well we rest.

What makes this connection especially important is that sleep isn’t just a nightly routine — it’s a biological reset that pollution can quietly disrupt without us noticing.

From early childhood through older adulthood, disrupted sleep compounds health risks — making air quality a quiet but consistent influence on sleep health.

The hidden link between air pollution and sleep

Sleep is shaped by far more than light, noise, or bedtime habits. The air we breathe—hour after hour, night after night—plays a subtle but powerful role in how deeply we sleep, how often we wake, and how well the body recovers overnight.

Learn how pollution affects exercise performance and health—and how to adjust workouts when air indoor and outdoor air quality shifts.

","Most of us exercise to strengthen our bodies and minds, yet the air we breathe during a workout is often overlooked. Air quality can significantly affect both exercise performance and overall health, particularly during high-intensity or prolonged workouts. As breathing rate increases, exposure to airborne pollutants increases along with it. In enclosed spaces like gyms and studios, poor ventilation can allow pollutants to build up, potentially undermining the benefits of physical activity. With the right awareness and a few practical adjustments, it’s possible to protect your lungs and get more out of every workout. Here’s how air quality affects exercise—and what to do about it. How air quality impacts your workout When you exercise, your breathing deepens and quickens. While this flood of oxygen fuels your muscles, it also means you’re inhaling more of whatever else is in the air: dust, mold, volatile organic compounds (VOCs) from cleaning products, and even PM2.5 —tiny particulate matter measuring less than 2.5 microns in diameter—can enter your lungs and circulate throughout the body. Studies confirm that indoor air pollution levels in gyms often surpass WHO safety limits (1). During a high-intensity workout, you might inhale 90 liters of air per minute or more, compared to just 6 liters at rest (2). That’s 18 times more pollutants entering your lungs and bloodstream—where they can trigger inflammation and limit oxygen delivery to working muscles. Both PM2.5 and gases like carbon dioxide (CO2) accumulate quickly in enclosed spaces. These irritants inflame airways, making it harder to breathe deeply and efficiently. Over time, this can lead to chronic oxidative stress, weakening lung function and endurance. A 2018 study found that gyms in Brazil, France, and other areas of Europe had CO2 levels exceeding 1,000 ppm, a threshold linked to cognitive decline and fatigue (3). Poor ventilation was the primary contributor. Indoor air can harbor two to five times more pollutants than outdoor air, according to the U.S. EPA (4). Why indoor air quality matters during exercise It’s easy to assume that indoor workout spaces are inherently cleaner than the air outdoors. In reality, indoor air quality can vary widely depending on ventilation, occupancy, and cleaning practices. During exercise, deeper and faster breathing increases exposure to airborne pollutants—even when they’re present at levels that might go unnoticed at rest. A gym that looks clean or smells fresh may still contain elevated levels of particulate matter or carbon dioxide, particularly during busy classes or peak hours. This doesn’t mean indoor exercise is unsafe—it means air quality plays a larger role in workouts than many people realize, and that managing ventilation and filtration can make a meaningful difference. Health risks of exercising in polluted air The effects of poor air quality are measurable, both immediately and over time. Fatigue and reduced performance: Exposure to PM2.5 has been found to increase fatigue, affecting athletic performance (5). Respiratory issues: Regular exposure to air pollutants is linked to asthma-like symptoms and decreased lung capacity, even in healthy individuals, due to increased respiratory demands (6). Cardiovascular risks: A systematic review of studies focused on endurance exercise and air pollution shows that athletes exposed to elevated PM2.5 levels were significantly impacted with cardiovascular health problems (7). Mental health impacts: Chronic inflammation from poor air quality is associated with increased risk of depression and anxiety, undermining the mood-boosting effects of physical activity (8). When to adjust your workout for air quality Air quality doesn’t have to be “Hazardous” to affect exercise performance. Because breathing rates increase during physical activity, even moderate pollution can have a greater impact during intense or prolonged workouts. The key is knowing whether you’re responding to indoor air conditions or outdoor pollution levels—and adjusting accordingly. Indoors: watch ventilation and buildup For indoor workouts, elevated PM2.5 levels or carbon dioxide (CO₂) concentrations above 1,000 parts per million (ppm) can signal that ventilation may be inadequate—especially in crowded or enclosed spaces. When these levels rise, lowering workout intensity, shortening duration, improving ventilation, or choosing a less crowded space can help reduce unnecessary strain on the lungs and cardiovascular system.Outdoors: use air quality ranges to guide decisionsFor outdoor exercise, PM2.5 and overall air quality levels are more useful decision tools. As a general guide: Good (0–25): Air quality is good. Outdoor exercise is generally safe. Moderate (26–50): Air quality is acceptable, but sensitive individuals may notice symptoms during outdoor exercise. Moderately Unhealthy (51–100): Pollutants may affect breathing even in healthy individuals. Consider exercising indoors or keeping outdoor workouts shorter and less intense. Unhealthy for Sensitive Groups (101–150): Everyone may be affected, especially those with heart or lung conditions. Indoor exercise is the safer choice. Very Unhealthy (151–200): Health effects are more likely for everyone. Avoid outdoor exercise. Hazardous (201–500): Air quality is poor enough to pose serious health risks. Stay indoors and avoid physical exertion. Using these ranges helps shift workouts to safer times, locations, or environments—without avoiding exercise altogether. Using air quality data to plan your workouts Air quality can change quickly due to traffic patterns, weather, and human activity. Pollution levels that are low early in the day may rise within hours, particularly during rush hour or in enclosed indoor spaces with high occupancy. Checking real-time air quality data and short-term forecasts helps you decide when and where to exercise with less exposure. Monitoring pollutants like PM2.5 and carbon dioxide allows you to adjust workout timing, intensity, or location accordingly—such as exercising earlier, choosing a less crowded space, or prioritizing indoor workouts when outdoor air quality is poor. Indoor vs. Outdoor Exercise: Which Is Better? When air quality is poor, the choice between exercising indoors or outdoors isn’t always straightforward. Outdoor workouts may offer better airflow, but they also expose you directly to pollution from traffic, industry, wildfire smoke, and other airborne contaminants. Indoor exercise can reduce exposure when ventilation and filtration are adequate, but poorly ventilated gyms or studios can allow pollutants like PM2.5 to accumulate—especially during busy classes or peak hours. In general, the better option depends on conditions: When outdoor air quality is good, exercising outside or ventilating indoor spaces can be beneficial. When outdoor air quality is poor, well-filtered and properly ventilated indoor environments are often the safer choice. Monitoring air quality both indoors and outdoors helps you choose the option that minimizes exposure while still supporting your fitness goals. How to exercise safely indoors Indoor exercise can be made safer with a few practical adjustments. Paying attention to ventilation, filtration, and air quality helps reduce unnecessary exposure during workouts. Choosing a gym or fitness studio: Prioritize facilities with high performance air purifiers. Ask staff about their ventilation systems and cleaning protocols.

This is especially true for disadvantaged or underserved schools near major sources of air pollution. Improving air quality in your school can seem complicated and daunting. But clean air can provide numerous returns by helping: prevent illnesses from airborne infections ensure that your school can conduct in-person classroom instruction improve long-term, school-wide academic performance Every school’s path to becoming a Clean Air School is unique. In many cases, schools can follow these steps for a comprehensive approach to air quality challenges that will best serve the needs of students and teachers: On-site air quality assessment Installation and maintenance Air quality verification and monitoring Maintenance and renewal 1. On-site air quality assessment The first step toward clean air at school is a thorough evaluation and assessment (virtual or in-person) of the school site. As you begin to determine your school’s air quality needs, several critical factors must be considered to identify specific air quality challenges and possible solutions. Local sources of pollution The degree to which your school is affected by air pollution is a major factor in determining your specific air filtration needs and how extensive filtration technology may be throughout your school site. Schools located near highways, busy roads, or heavy industrial polluters like factories or ports may face higher levels of PM2.5,(particulate matter with a diameter size of 2.5 microns or smaller), ultrafine particles (UFPs), and chemicals that can be difficult to control. Click here to see why particle size matters... Air pollution and COVID-19 (a serious disease, often fatal, that is caused by the SARS-CoV-2 virus)outcomes are also closely linked. Common air pollutants, especially PM2.5, may increase the risk of illness or death from COVID-19. In these cases, air filtration that can adequately address high volumes of both indoor and outdoor air pollution are necessary. School age and HVAC design The average school building in the United States is between 37 and 46 years old (1) (2).Heating, ventilation, and air conditioning (HVAC) design has changed dramatically during this period. Some schools have central HVAC systems, while others may have individual heating and cooling units for every classroom. This can drastically alter the air filtration needs from school to school. Maintenance Maintenance and filter replacement are key to long-term air filtration performance. Proper installation and filter replacements must both be taken into account when budgeting for long-term air filtration needs. Air pollution sources and HVAC system design both affect the type of solution you’ll need as well as how often you’ll need to replace filters. Schools in heavily polluted areas may require more frequent filter replacements as filters quickly build up with airborne particles.

Expert consultation In many cases, expert consultation is needed to adequately assess every factor relevant to purchasing, installing, and maintaining air filtration technologies. An onsite or virtual evaluation conducted by subject matter experts in school air quality can help your school identify air quality issues and possible solutions with the following steps: building walkthrough to document facility details spot measurements of air quality indicators to assess major sources of air pollution inspection of air handlers and air distribution systems to determine filtration needs written report detailing air quality challenges and proposed solutions customized to your school’s needs Localized air filtration solutions, such as stand-alone air purifiers, may be helpful for classrooms without centralized HVAC systems. A high-performance system can provide several full air changes per hour (ACH), removing up to 99.5% of airborne particles in a classroom. Personal air purifiers can also help by providing individual desks and workstations with a direct supply of clean air, delivering air filtration efficiencies up to 99% for airborne particles. However, customized minimum efficiency reporting value (MERV)16 HVAC air filtration is recommended to capture infectious particles and pollutants across the largest area possible. MERV 13 filtration is currently a popular choice for filtration in schools. But MERV 13 only captures up to 50% of airborne particles between 0.3-1.0 microns. MERV 13, due to its lower efficiency, might require extensive mechanical ventilation. This reduces energy efficiency and may not be feasible during extreme weather. MERV 16 is nearly twice as efficient as MERV 13, capturing up to 95% of airborne particles in the 0.3-1.0 micron range. MERV 16 is nearly twice as efficient as MERV 13, capturing up to 95% of airborne particles in the 0.3-1.0 micron range (see Figure 1) and requiring little to no ventilation (3). Figure 1: MERV air filtration efficiency for different particle sizes. MERV 16 efficiencies are detailed at the bottom of the chart (Source: ASHRAE Standard 52.2-2017) (4). During field tests in classrooms, MERV 16 filtration has met and even exceeded these efficiency ratings (5). 2. Installation and maintenance Many schools may be eligible for turnkey air filtration solutions that have already been successfully designed and implemented for schools with similar air quality needs. In schools where customization is necessary, a high degree of expertise may be required to properly install and maintain air filtration systems for maximum efficiency and filter lifespan. Some considerations for installation and long-term maintenance planning may include the following. HVAC upgrades HVAC systems are sometimes outdated, inefficient, or incompatible with MERV 16 technology. System upgrades and custom installation plans may be necessary to achieve the maximum filtration capabilities and protection from airborne infections. Energy management Unlike MERV 13, MERV 16 systems do not require 100% ventilation to filter indoor air pollutants. This means that your HVAC system can be turned on and off as needed to save energy. Reduced ventilation can also reduce your school’s carbon footprint while still achieving up to 95% filtration efficiency and protecting classrooms from outdoor air pollution (6). Smart thermostats and other energy management systems can help your school program air filtration systems for use during school hours when students are in class. Air quality monitoring and smart technology Air quality monitoring coupled with smart technology, such as smart thermostats, can help automate filtration behavior with predetermined protocols: HVAC Systems: Smart thermostats are programmed to keep HVAC on “Fan On” mode for clean air even when cooling or heating are off. High-Capacity Stand-Alone Systems: Filtration systems are coupled with occupancy sensors or timers that can integrate with air quality monitoring to turn systems off and save energy when classrooms are empty. 3. Air quality verification and monitoring Indoor air pollution in many schools, especially UFPs and PM2.5, has long resulted in poor student health outcomes and cognitive development (7) (8). These pollutants will likely remain a major threat. Monitoring air quality is critical to ensuring that air filtration technologies are sufficiently providing clean air. Air quality data can also help demonstrate long-term improvements in connection with other school-wide data. Setting up real-time indoor and outdoor air quality monitoring can have the following benefits: Provide a live feed of indoor air quality data to show that air filtration technology is functioning properly Connect to mobile air quality apps so that all students, teachers, and parents can view live school air quality Set up email alerts for certain air quality thresholds that can provide school staff with warnings about poor air quality Demonstrate actual reductions in indoor pollutants to display improvements in indoor air versus outdoor air as a result of air filtration Document long-term improvements in indoor air quality and help sustain clean air environments in classrooms Generate air quality reports to be used with other school data, such as test scores or absences due to illness, to draw correlations between improved air quality and other improvements A real-time public air quality dashboard displaying indoor and outdoor data to parents, teachers, and other school stakeholders can also demonstrate the value of clean air in real time. This data can be displayed either on public smart TV monitors or a live, customized air quality feed using air quality monitoring software. The benefits of clean air are extensive. Monitoring air quality can help schools show just how much reductions in air pollution can help improve health and academics. Numerous studies have already illustrated the very real health and academic consequences of airborne particulate matter for students with allergies and asthma, including (9) (10) (11): a 2016 study suggesting that indoor pollen concentrations are directly linked to lower test scores a 2017 study finding that students with asthma were more likely to miss school and experience disruptive anxiety symptoms about academic outcomes as a result of poor indoor air quality a 2019 study indicating that school absences due to asthma can make academic outcomes progressively worse over time, especially for students in highly polluted urban areas Become a Clean Air SchoolHelp protect the health of students, teachers, and staff LEARN MORE 4. Maintenance and renewal Clean Air Schools can display a customized placard that indicates to the public that your school meets stringent infection control and indoor air quality requirements (see Figure 2 for an example). Figure 2: Example of Clean Air School wall plaque that can be displayed in public view as long as your school meets the technology and filter replacement requirements. As long as your school adequately maintains HVAC air filtration systems for maximum efficiency and replaces filters at recommended intervals, your school can continue to display your Clean Air School status to all parents, teachers, and stakeholders. Typical maintenance and renewal requirements include replacement of all air filtration systems every 12 months. Other data that can affect your renewal requirements include: specific installation setup air quality sensor data usage patterns (i.e., how long you use air filtration each day) The takeaway Clean air has become central to the conversation around safe classroom environments. But clean air also has many other benefits, helping schools to reduce harmful pollutants in classroom air, reduce absences, and increase student performance. Equal access to clean air can also help close the achievement gap across all schools. Expert help and customized solutions can help ensure that your school can access the most effective air filtration and be rewarded with the benefits of clean air.","

Clean air is critical in helping students and staff stay healthy.

But access to clean air has long been an issue for many schools. This is especially true for disadvantaged or underserved schools near major sources of air pollution.

Improving air quality in your school can seem complicated and daunting. But clean air can provide numerous returns by helping:

prevent illnesses from airborne infections
ensure that your school can conduct in-person classroom instruction
improve long-term, school-wide academic performance

Every school’s path to becoming a Clean Air School is unique. In many cases, schools can follow these steps for a comprehensive approach to air quality challenges that will best serve the needs of students and teachers:

On-site air quality assessment
Installation and maintenance
Air quality verification and monitoring
Maintenance and renewal

1. On-site air quality assessment

The first step toward clean air at school is a thorough evaluation and assessment (virtual or in-person) of the school site.

As you begin to determine your school’s air quality needs, several critical factors must be considered to identify specific air quality challenges and possible solutions.

Local sources of pollution

The degree to which your school is affected by air pollution is a major factor in determining your specific air filtration needs and how extensive filtration technology may be throughout your school site.

Schools located near highways, busy roads, or heavy industrial polluters like factories or ports may face higher levels of PM2.5,(particulate matter with a diameter size of 2.5 microns or smaller), ultrafine particles (UFPs), and chemicals that can be difficult to control.

Click here to see why particle size matters...

Air pollution and COVID-19 (a serious disease, often fatal, that is caused by the SARS-CoV-2 virus)outcomes are also closely linked. Common air pollutants, especially PM2.5, may increase the risk of illness or death from COVID-19.

In these cases, air filtration that can adequately address high volumes of both indoor and outdoor air pollution are necessary.

School age and HVAC design

The average school building in the United States is between 37 and 46 years old (1) (2).Heating, ventilation, and air conditioning (HVAC) design has changed dramatically during this period.

Some schools have central HVAC systems, while others may have individual heating and cooling units for every classroom. This can drastically alter the air filtration needs from school to school.

Maintenance

Maintenance and filter replacement are key to long-term air filtration performance. Proper installation and filter replacements must both be taken into account when budgeting for long-term air filtration needs.

Air pollution sources and HVAC system design both affect the type of solution you’ll need as well as how often you’ll need to replace filters. Schools in heavily polluted areas may require more frequent filter replacements as filters quickly build up with airborne particles.

Funding assistance

Funding assistance may be available for schools in need, but schools may face challenges with securing a budget for air quality improvements.

For more information or assistance on grants and funding, email info@iqairfoundation.org or call 866-760-8180.

Expert consultation

In many cases, expert consultation is needed to adequately assess every factor relevant to purchasing, installing, and maintaining air filtration technologies.

An onsite or virtual evaluation conducted by subject matter experts in school air quality can help your school identify air quality issues and possible solutions with the following steps:

\nbuilding walkthrough to document facility details
\nspot measurements of air quality indicators to assess major sources of air pollution\n
\ninspection of air handlers and air distribution systems to determine filtration needs
\nwritten report detailing air quality challenges and proposed solutions customized to your school’s needs

Localized air filtration solutions, such as stand-alone air purifiers, may be helpful for classrooms without centralized HVAC systems. A high-performance system can provide several full air changes per hour (ACH), removing up to 99.5% of airborne particles in a classroom.

Personal air purifiers can also help by providing individual desks and workstations with a direct supply of clean air, delivering air filtration efficiencies up to 99% for airborne particles.

However, customized minimum efficiency reporting value (MERV)16 HVAC air filtration is recommended to capture infectious particles and pollutants across the largest area possible.

$\"How$

MERV 13 filtration is currently a popular choice for filtration in schools. But MERV 13 only captures up to 50% of airborne particles between 0.3-1.0 microns.

MERV 13, due to its lower efficiency, might require extensive mechanical ventilation. This reduces energy efficiency and may not be feasible during extreme weather.

MERV 16 is nearly twice as efficient as MERV 13, capturing up to 95% of airborne particles in the 0.3-1.0 micron range.

MERV 16 is nearly twice as efficient as MERV 13, capturing up to 95% of airborne particles in the 0.3-1.0 micron range (see Figure 1) and requiring little to no ventilation (3).

$\"MERV$

Figure 1: MERV air filtration efficiency for different particle sizes. MERV 16 efficiencies are detailed at the bottom of the chart (Source: ASHRAE Standard 52.2-2017) (4).

During field tests in classrooms, MERV 16 filtration has met and even exceeded these efficiency ratings (5).

2. Installation and maintenance

Many schools may be eligible for turnkey air filtration solutions that have already been successfully designed and implemented for schools with similar air quality needs.

In schools where customization is necessary, a high degree of expertise may be required to properly install and maintain air filtration systems for maximum efficiency and filter lifespan.

Some considerations for installation and long-term maintenance planning may include the following.

HVAC upgrades

HVAC systems are sometimes outdated, inefficient, or incompatible with MERV 16 technology.

System upgrades and custom installation plans may be necessary to achieve the maximum filtration capabilities and protection from airborne infections.

Energy management

Unlike MERV 13, MERV 16 systems do not require 100% ventilation to filter indoor air pollutants. This means that your HVAC system can be turned on and off as needed to save energy.

Reduced ventilation can also reduce your school’s carbon footprint while still achieving up to 95% filtration efficiency and protecting classrooms from outdoor air pollution (6).

Smart thermostats and other energy management systems can help your school program air filtration systems for use during school hours when students are in class.

Air quality monitoring and smart technology

Air quality monitoring coupled with smart technology, such as smart thermostats, can help automate filtration behavior with predetermined protocols:

\nHVAC Systems: Smart thermostats are programmed to keep HVAC on “Fan On” mode for clean air even when cooling or heating are off.
\nHigh-Capacity Stand-Alone Systems: Filtration systems are coupled with occupancy sensors or timers that can integrate with air quality monitoring to turn systems off and save energy when classrooms are empty.

3. Air quality verification and monitoring

Indoor air pollution in many schools, especially UFPs and PM2.5, has long resulted in poor student health outcomes and cognitive development (7) (8). These pollutants will likely remain a major threat.

Monitoring air quality is critical to ensuring that air filtration technologies are sufficiently providing clean air. Air quality data can also help demonstrate long-term improvements in connection with other school-wide data.

Setting up real-time indoor and outdoor air quality monitoring can have the following benefits:

\nProvide a live feed of indoor air quality data to show that air filtration technology is functioning properly
\nConnect to mobile air quality apps so that all students, teachers, and parents can view live school air quality
\nSet up email alerts for certain air quality thresholds that can provide school staff with warnings about poor air quality
\nDemonstrate actual reductions in indoor pollutants to display improvements in indoor air versus outdoor air as a result of air filtration
\nDocument long-term improvements in indoor air quality and help sustain clean air environments in classrooms
\nGenerate air quality reports to be used with other school data, such as test scores or absences due to illness, to draw correlations between improved air quality and other improvements

A real-time public air quality dashboard displaying indoor and outdoor data to parents, teachers, and other school stakeholders can also demonstrate the value of clean air in real time. This data can be displayed either on public smart TV monitors or a live, customized air quality feed using air quality monitoring software.

The benefits of clean air are extensive. Monitoring air quality can help schools show just how much reductions in air pollution can help improve health and academics.

Numerous studies have already illustrated the very real health and academic consequences of airborne particulate matter for students with allergies and asthma, including (9) (10) (11):

a 2016 study suggesting that indoor pollen concentrations are directly linked to lower test scores
a 2017 study finding that students with asthma were more likely to miss school and experience disruptive anxiety symptoms about academic outcomes as a result of poor indoor air quality
a 2019 study indicating that school absences due to asthma can make academic outcomes progressively worse over time, especially for students in highly polluted urban areas

4. Maintenance and renewal

Clean Air Schools can display a customized placard that indicates to the public that your school meets stringent infection control and indoor air quality requirements (see Figure 2 for an example).

$\"Clean$

Figure 2: Example of Clean Air School wall plaque that can be displayed in public view as long as your school meets the technology and filter replacement requirements.

As long as your school adequately maintains HVAC air filtration systems for maximum efficiency and replaces filters at recommended intervals, your school can continue to display your Clean Air School status to all parents, teachers, and stakeholders.

Typical maintenance and renewal requirements include replacement of all air filtration systems every 12 months. Other data that can affect your renewal requirements include:

specific installation setup
air quality sensor data
usage patterns (i.e., how long you use air filtration each day)

The takeaway

Clean air has become central to the conversation around safe classroom environments. But clean air also has many other benefits, helping schools to reduce harmful pollutants in classroom air, reduce absences, and increase student performance.

Equal access to clean air can also help close the achievement gap across all schools.

Expert help and customized solutions can help ensure that your school can access the most effective air filtration and be rewarded with the benefits of clean air.

Vehicle exhaust is a major source of PM2.5, ultrafine particles (UFPs), chemicals, and volatile organic compounds (VOCs).1,2 Air filtration must be designed not only to help reduce outdoor air pollution that can seep indoors but also remove indoor air pollutants from furnishings, construction materials, and personal hygiene products that can impact employee health and productivity.

Inspection of air handlers and air distribution: Current facility HVAC and air filtration technology, including outstanding maintenance and upgrades, are noted. Detailed analysis: A written report is shared with facility stakeholders, describing air quality issues and suggesting customized air filtration solutions to help the building meet Clean Air Facility requirements. Based on evaluation results, one or more of the following solutions may be proposed: HVAC air filtration: For many buildings, HVAC air filtration is the most logical choice for air pollution mitigation. This type of air quality solution uses centralized airflow and filtration mechanisms to help deliver clean air to the entire building through facility ductwork. Localized air filtration solutions: Stand-alone air purifiers or room air purifiers can provide clean air to workspaces that may not have access to a centralized HVAC system or may be required depending on the day to day activities that take place within the facility. A high-performance system can provide several air changes per hour (ACH) and filter up to 99.5% of airborne particles in any given workspace. Individualized air purification: Personal air purifiers can help shield employees at individual workstations from air pollutants and airborne infections, delivering clean air filtered from up to 99% of airborne particles directly to a person’s breathing zone. Many buildings have traditionally relied on HVAC air filters rated MERV 13 or lower according to the MERV efficiency system based on the ASHRAE 52.2 standard.6 However, MERV 13 is tested to capture up to 50% of airborne particles ranging from 0.3-1.0 microns in size. This can leave up to half of the most dangerous airborne particles unfiltered, including airborne infections and ultrafine particles (UFPs). MERV 13 filters also require extensive mechanical ventilation to effectively dilute indoor concentrations of airborne particles. This can negatively affect a building in two ways: increased penetration of outdoor air can reduce building energy efficiency by disrupting indoor climate control and requiring increased HVAC operation hours for thermal comfort ventilation with outdoor air can bring in outdoor air pollutants that can cause poor indoor air quality, reducing the efficiency of air filtration systems IQAir filtration technology provides high-efficiency HVAC panel filters with ultralow pressure drop. In fact, NanoMax filtration technology exceeds MERV 16 standards with only the pressure drop of an average MERV 8 filter. NanoMax filters are suggested as an alternative to counter these potential downsides of traditional MERV 13 air filters. NanoMax filters are tested to capture up to 96 percent of airborne particles between 0.3-1.0 microns and at least 90% of UFPs less than 0.1 microns.7 Their high efficiency eliminates the need for additional mechanical ventilation beyond building code requirements. The high efficiency of NanoMax filters reduces the need for additional mechanical ventilation beyond building code requirements.

Po Valley will host the upcoming Winter Olympics when pollution is at its peak. What can be done to ensure athlete and spectator safety?

","In February 2026, Milan, Italy and the surrounding Po Valley will host the Winter Olympics, a global celebration of athletic excellence set against one of Europe’s most persistent winter air quality challenges. The Po Valley in northern Italy routinely experiences winter smog. This intersection of Olympic athletic competition and poor air quality raises concerns for the health and performance of both athletes and spectators. Where will the 2026 Olympic games be held? The 2026 Milan-Cortina Winter Olympic games will be held in three northern provinces of Italy – Lombardy, South Tyrol, and Veneto from February 6 through 22 (1). While most of the stadiums, arenas, and parks are in the surrounding Alps, the two largest participating cities – Milan and Verona – lie in the Po Valley. Five arenas and stadiums in Milan will host indoor-only events and the opening ceremony, while Verona Olympic Arena will host the closing ceremonies. Other venue locations include: Anterselva / Antholz, South Tyrol Bormio, Lombardy Cortina d’Ampezzo, Veneto Livigno, Lombardy Predazzo, Trentino Tesero, Trentino All locations, with the exceptions of Tesero and Verona, will house Olympic Villages where athletes will reside during the games. Why is the Po Valley’s air quality poor in winter? The Po Valley’s unique geography plays a central role in trapping pollutants: the valley is hemmed in by the Alps to the north and the Apennine Mountains to the south, creating a natural basin that traps cold air and pollutants. This \"bowl effect\" is compounded by meteorological conditions, particularly in winter, when temperature inversions occur. During these inversions, a layer of warm air settles above the cooler air near the ground, acting like a lid that prevents pollutants from dispersing upward or outward. As a result, pollutants can linger over the valley for days or even weeks. Human activity degrades the region’s poor air quality. Human activity affects the region’s air quality. The Po Valley is home to some of Italy’s most industrialized areas, where factories release PM2.5 – particulate matter measuring 2.5 micrometers in diameter or smaller – and nitrogen oxides (NO2) (2). Agriculture also contributes pollutants, as livestock farming produces ammonia, which reacts with industrial and vehicle emissions to create secondary particulate matter. According to a 2024 study, livestock farming may be responsible for as much as a quarter of Lombardy’s air pollution (3). Smoke from residential wood burning impacts winter air quality in the Po Valley (4). Vehicle emissions, particularly in major cities like Milan and Turin, are also sources of nitrogen dioxide and PM2.5 (5). These geographic and emissions-related factors are reflected in Milan’s long-term air quality data—but annual averages can mask the severity of winter pollution. In 2024, Milan's annual average PM2.5 concentration was 17 µg/m3. This was 3.4 times the WHO annual guideline of 5 µg/m3. However, this figure blends relatively cleaner summer conditions with much higher winter concentrations. During peak winter months, pollution levels rise sharply. In February 2025, Milan’s average monthly PM2.5 concentration was 32.1 µg/m3. These winter pollution episodes are often driven by stagnant air and temperature inversions rather than predictable daily emission cycles. Air quality in surrounding Alpine valleys may also be affected by residential wood burning combined with inversion conditions (6). Air quality lessons from past Olympics Previous Olympic host countries have struggled with poor air quality and have had to take measures to ensure health and safety. Beijing, China faced the potential for severe air pollution while hosting the 2008 Summer Olympics – and officials took proactive measures. In the months leading up to the Games, the U.S. Embassy in Beijing installed a regulatory-grade air quality monitor that exposed hazardous air quality in the city. Chinese authorities enacted sweeping temporary measures, including shutting down factories, and restricting vehicle traffic. Chinese officials implemented a robust policy shift in 2013, a year of terrible air quality for the country. The official policy response focused on long term air quality improvements – tougher coal-fired plant emissions standards, further vehicle restrictions, and initiatives to cut coal-fired home heating with electric or gas heaters (7).

In February 2026, Milan, Italy and the surrounding Po Valley will host the Winter Olympics, a global celebration of athletic excellence set against one of Europe’s most persistent winter air quality challenges.

The Po Valley in northern Italy routinely experiences winter smog. This intersection of Olympic athletic competition and poor air quality raises concerns for the health and performance of both athletes and spectators.

Where will the 2026 Olympic games be held?

The 2026 Milan-Cortina Winter Olympic games will be held in three northern provinces of Italy – Lombardy, South Tyrol, and Veneto from February 6 through 22 (1). While most of the stadiums, arenas, and parks are in the surrounding Alps, the two largest participating cities – Milan and Verona – lie in the Po Valley. Five arenas and stadiums in Milan will host indoor-only events and the opening ceremony, while Verona Olympic Arena will host the closing ceremonies.

Other venue locations include:

Anterselva / Antholz, South Tyrol
\n
\nBormio, Lombardy
\n
Cortina d’Ampezzo, Veneto
\n
\nLivigno, Lombardy
\n
Predazzo, Trentino
\n
Tesero, Trentino
\n

All locations, with the exceptions of Tesero and Verona, will house Olympic Villages where athletes will reside during the games.

Why is the Po Valley’s air quality poor in winter?

The Po Valley’s unique geography plays a central role in trapping pollutants: the valley is hemmed in by the Alps to the north and the Apennine Mountains to the south, creating a natural basin that traps cold air and pollutants.

This \"bowl effect\" is compounded by meteorological conditions, particularly in winter, when temperature inversions occur. During these inversions, a layer of warm air settles above the cooler air near the ground, acting like a lid that prevents pollutants from dispersing upward or outward. As a result, pollutants can linger over the valley for days or even weeks.

Human activity degrades the region’s poor air quality.

Human activity affects the region’s air quality. The Po Valley is home to some of Italy’s most industrialized areas, where factories release PM2.5 – particulate matter measuring 2.5 micrometers in diameter or smaller – and nitrogen oxides (NO2) (2).

Agriculture also contributes pollutants, as livestock farming produces ammonia, which reacts with industrial and vehicle emissions to create secondary particulate matter. According to a 2024 study, livestock farming may be responsible for as much as a quarter of Lombardy’s air pollution (3).

Smoke from residential wood burning impacts winter air quality in the Po Valley (4). Vehicle emissions, particularly in major cities like Milan and Turin, are also sources of nitrogen dioxide and PM2.5 (5). These geographic and emissions-related factors are reflected in Milan’s long-term air quality data—but annual averages can mask the severity of winter pollution.

In 2024, Milan's annual average PM2.5 concentration was 17 µg/m3. This was 3.4 times the WHO annual guideline of 5 µg/m3. However, this figure blends relatively cleaner summer conditions with much higher winter concentrations.

During peak winter months, pollution levels rise sharply. In February 2025, Milan’s average monthly PM2.5 concentration was 32.1 µg/m3.

These winter pollution episodes are often driven by stagnant air and temperature inversions rather than predictable daily emission cycles. Air quality in surrounding Alpine valleys may also be affected by residential wood burning combined with inversion conditions (6).

Air quality lessons from past Olympics

Previous Olympic host countries have struggled with poor air quality and have had to take measures to ensure health and safety.

Beijing, China faced the potential for severe air pollution while hosting the 2008 Summer Olympics – and officials took proactive measures. In the months leading up to the Games, the U.S. Embassy in Beijing installed a regulatory-grade air quality monitor that exposed hazardous air quality in the city. Chinese authorities enacted sweeping temporary measures, including shutting down factories, and restricting vehicle traffic.

Chinese officials implemented a robust policy shift in 2013, a year of terrible air quality for the country. The official policy response focused on long term air quality improvements – tougher coal-fired plant emissions standards, further vehicle restrictions, and initiatives to cut coal-fired home heating with electric or gas heaters (7). By the 2022 Beijing Winter Olympics, air pollution in the city was half that of both 2008 and 2013 (8).

Rio de Janeiro was confronted with its own environmental crisis during the 2016 Olympics. While polluted water dominated the headlines, air quality also remained a persistent concern due to rapid development and 2.7 million vehicles in the city (9). To test those concerns, the Reuters news agency tested air quality at several Olympic sites across the city, finding a peak 24-hour average PM2.5 concentration of 65 µg/m3 at the Olympic Stadium (10).

CADR measures how quickly an air purifier cleans the air. Learn how it works—and why it should be considered alongside long-term performance metrics like CCM.

","When choosing an air purifier, one of the first numbers people encounter is CADR—but it is also one of the most misunderstood. CADR, or Clean Air Delivery Rate, measures how quickly an air purifier can clean the air in a space. It is often used to compare different models, but on its own it does not reflect how an air purifier performs in real-world conditions over time. CADR focuses on short-term performance—how quickly clean air is delivered under specific conditions—rather than how long that performance can be maintained. Understanding how CADR works—and how it differs from other metrics like CCM—can make it easier to choose a system that matches both the size of a space and how performance will hold over time. What CADR actually measures CADR reflects how quickly an air purifier removes particles from the air. It combines airflow and filter efficiency to estimate how fast clean air is delivered within a given space. In practical terms, this means CADR indicates how quickly airborne particles can be cleared—but not how consistently that performance will hold over time. CADR measures the removal rate of airborne particles as small as 0.09 microns to as large as 11 microns (1)(2). It reflects how filter efficiency and airflow interact within a given space, but is limited to measuring performance speed rather than long-term usage. CADR is often presented alongside CCM, but the two metrics reflect very different aspects of performance. CADR focuses on how quickly clean air is delivered, while CCM indicates how much pollution a system can handle before its performance begins to decline. The limitation of CADR: Speed vs long-term performance While CADR is commonly used to compare how quickly an air purifier works, it does not indicate how performance will hold over time. As filters load with particles and gases, airflow and efficiency can change—something CADR does not capture. Many air purifiers perform well when new but lose effectiveness as filters become saturated. As a result, CADR alone gives an incomplete—or even misleading—picture of how an air purifier will perform outside of controlled test conditions. CADR vs CCM: Speed vs endurance While CADR measures speed, CCM focuses on endurance. It tracks how much pollution an air purifier can remove over time before its performance begins to decline. CCM ratings are grouped into standardized tiers for particulate matter (P) and formaldehyde (F), which indicate how much pollution an air purifier can handle before its performance begins to decline. Higher tiers represent greater long-term filtration capacity and more stable performance over time. Particulate Matter Formaldehyde P1 3000 – 5000 mg F1 300 – 600 mg P2 5000 – 8000 mg F2 600 – 1000 mg P3 8000 – 12000 mg F3 1000 – 1500 mg P4 > 12,000 mg F4 > 1500 mg In practical terms, higher P and F values indicate that an air purifier can handle more pollution before its performance drops—making these tiers a useful way to compare long-term effectiveness. For example, a system rated at P4 can remove significantly more particulate matter before performance declines than one rated at P1. Compared to CADR, CCM reflects long-term filtration performance rather than short-term speed. In practice, CADR reflects how quickly an air purifier performs under initial test conditions, while CCM provides clearer insight into how that performance holds up over time. How to evaluate air purifier performance in real-world use Understanding how an air purifier is tested can help clarify how it will perform in real-world use. If a system is too small for a space, or if performance declines over time, airborne particles may remain present. Systems with higher CCM levels are more likely to maintain consistent performance over time, which can be especially relevant for sensitive or allergy-prone groups. CCM values reflect long-term filtration capacity. Some systems are designed to maintain performance over extended use, which is reflected in higher CCM values. Some air purifiers are designed to perform strongly across both metrics. For example, systems using high-efficiency filtration, such as IQAir systems using HyperHEPA filtration, are designed to capture ultrafine particles efficiently while maintaining long-term performance. Frequently Asked Questions What is the difference between CADR and CCM? CADR measures initial short-term performance quality, calculating the rate or speed of which airborne particulate matter is cleaned and recycled. CCM measures long-term performance longevity, calculating the sheer amount of pollutant particles that are collected by an air purifier before the device begins to lose efficiency. The key difference is the short-term versus long-term measurements. What is more important to consider, CADR or CCM? While both CADR and CCM are important to consider in general, CCM provides a clearer understanding of air purifier quality and filtration over time. When choosing an air purifier, CCM values give a direct ranking on which system is going to last the longest while maintaining powerful filtration. Do all air purifiers have CADR and/or CCM ratings?

See how EarthMuseum is teaching the next generation how to monitor air quality and address air pollution through data.

","“Our program gives students a way to work with real-world data—so they’re not just learning about air quality, they’re actually seeing it and responding to it,” said Janet Owen, Founder and Director of EarthMuseum Learn. Through its collaboration with IQAir, EarthMuseum Learn, a not-for-profit focused on global, cross-curricular education, is piloting Air We Breathe—an air quality learning and monitoring program that helps students understand pollution in context and think more critically about what it means (1). As part of a free wider learning program, schools use IQAir’s AirVisual Outdoor air quality monitors and AirVisual dashboard to measure the air around them and publish an analysis of those readings to a shared collaboration platform. Instead of relying on static examples, students work with live data—conditions that change throughout the day and can be followed over time. For many, it’s the first time air pollution is something they can track directly using data generated by their own school. Rather than focusing on a single location or data contributor, the program is designed to connect many, linking classrooms through a common learning framework and shared data. Learning that starts with context Developed with educators and subject experts, the Air We Breathe program is designed for students ages 7 to 14. It’s free for schools worldwide and built to fit into existing curricula. The program moves between history, science, and present-day air quality. Lessons explore how air pollution has developed over time, from early human activity through the industrial period and into the present. They also look at how air quality connects to health, climate, and the way communities function, with an opportunity to think about local innovation and action. That shared structure makes it possible for schools in different locations to engage with the same material at the same time, creating a common starting point for comparison. It’s not about delivering a fixed set of facts. Students are encouraged to question, discuss, and form their own views. As Owen put it, the program is built around “the ability to have conversations about what air quality and air pollution are, and what they mean in a worldview context.” That foundation becomes more meaningful once students begin working with real-world data. Working with data from their own environment Each school uses an IQAir AirVisual Outdoor monitor to measure local air quality. Those readings feed into the IQAir platform, where they can be accessed through the AirVisual app, desktop dashboard, and global air quality map. Students aren’t just checking the numbers. They follow how readings change over time, compare patterns across different days, and begin asking why those changes happen. Owen described it simply: students are “playing with the data, looking at the data, comparing their data with others.” For EarthMuseum Learn, the appeal of the system was not just the data itself, but how easily it could be used across different classrooms globally. Once tested, Owen said, “it was pretty straightforward to set up,” and “very communicative in terms of the data.” The platform also places those readings alongside a much wider network of stations, contributed by governments, organizations, and individuals around the world. That context makes it easier to see how local conditions fit into a broader picture. In practice, each school becomes one point within a much larger network of observations. Comparing across locations Students have the ability to look at their own data alongside readings from partner schools in other regions, from nearby cities to entirely different countries. Seeing those differences tends to raise immediate questions. Owen said students begin to ask, “Why are levels higher in one place than another? What local factors might be involved? How do infrastructure, geography, or policy play a role?” For the program, that exchange is central. It’s about “that ability to compare and contrast, to talk, to discuss, and to understand what’s happening in different places.” What starts as a local exercise becomes something shared, and something that allows students to see their community in a global context.

“Our program gives students a way to work with real-world data—so they’re not just learning about air quality, they’re actually seeing it and responding to it,” said Janet Owen, Founder and Director of EarthMuseum Learn.

Through its collaboration with IQAir, EarthMuseum Learn, a not-for-profit focused on global, cross-curricular education, is piloting Air We Breathe—an air quality learning and monitoring program that helps students understand pollution in context and think more critically about what it means (1).

As part of a free wider learning program, schools use IQAir’s AirVisual Outdoor air quality monitors and AirVisual dashboard to measure the air around them and publish an analysis of those readings to a shared collaboration platform. Instead of relying on static examples, students work with live data—conditions that change throughout the day and can be followed over time.

For many, it’s the first time air pollution is something they can track directly using data generated by their own school.

Rather than focusing on a single location or data contributor, the program is designed to connect many, linking classrooms through a common learning framework and shared data.

Learning that starts with context

Developed with educators and subject experts, the Air We Breathe program is designed for students ages 7 to 14. It’s free for schools worldwide and built to fit into existing curricula.

The program moves between history, science, and present-day air quality. Lessons explore how air pollution has developed over time, from early human activity through the industrial period and into the present. They also look at how air quality connects to health, climate, and the way communities function, with an opportunity to think about local innovation and action. That shared structure makes it possible for schools in different locations to engage with the same material at the same time, creating a common starting point for comparison.

It’s not about delivering a fixed set of facts. Students are encouraged to question, discuss, and form their own views. As Owen put it, the program is built around “the ability to have conversations about what air quality and air pollution are, and what they mean in a worldview context.”

That foundation becomes more meaningful once students begin working with real-world data.

Working with data from their own environment

Each school uses an IQAir AirVisual Outdoor monitor to measure local air quality. Those readings feed into the IQAir platform, where they can be accessed through the AirVisual app, desktop dashboard, and global air quality map.

Students aren’t just checking the numbers. They follow how readings change over time, compare patterns across different days, and begin asking why those changes happen.

Owen described it simply: students are “playing with the data, looking at the data, comparing their data with others.”

For EarthMuseum Learn, the appeal of the system was not just the data itself, but how easily it could be used across different classrooms globally. Once tested, Owen said, “it was pretty straightforward to set up,” and “very communicative in terms of the data.”

The platform also places those readings alongside a much wider network of stations, contributed by governments, organizations, and individuals around the world. That context makes it easier to see how local conditions fit into a broader picture. In practice, each school becomes one point within a much larger network of observations.

Comparing across locations

Students have the ability to look at their own data alongside readings from partner schools in other regions, from nearby cities to entirely different countries.

Seeing those differences tends to raise immediate questions. Owen said students begin to ask, “Why are levels higher in one place than another? What local factors might be involved? How do infrastructure, geography, or policy play a role?” For the program, that exchange is central. It’s about “that ability to compare and contrast, to talk, to discuss, and to understand what’s happening in different places.”

What starts as a local exercise becomes something shared, and something that allows students to see their community in a global context.

Understanding how air quality data is created

Alongside real-time monitoring, students take manual readings at set intervals, recording and sharing those observations through EarthMuseum Learn’s developing collaborative platform.

For many, this is their first experience working with environmental data in a structured way. It makes them more comfortable reading the numbers and talking about what those numbers mean.

Because those observations are shared across schools, they don’t stay local—they contribute to a broader, collective view.

From observation to response

Students are encouraged to consider what their observations mean in practical terms—for themselves, for their school, and for the wider community. Sometimes that may lead to small changes in the school environment. In other cases, it can develop into campaigns or presentations shared with local decision-makers. Owen said, “Students see that data isn’t just something on a screen, or something collected in a vacuum. They see how it’s interpreted—and how it can help make an impact in their world.”

That thinking is shaped not only by their own data, but by what they see happening in other schools.

As Owen framed it: “What does that mean for me individually? What does that mean for us as a school? What does that mean for the community?”

Teachers involved in early pilots have already seen the conversation extend beyond the classroom. Students bring the subject home with them, and it starts to shape discussions with teachers, parents, and peers.

“There’s a real appetite… to have those conversations—not just with each other, but with teachers and with parents,” Owen said.

Building a connected model

Work with schools in the UK now includes international partners, with classrooms in Europe, the Middle East, and Asia beginning to take part. Additional school networks are in discussion.

As more schools install monitors and publish data, the project is gradually forming a distributed network of classrooms, each contributing its own data and perspective.

Because the same monitoring and platform infrastructure can be used across regions, schools are able to participate in a shared system without needing to adapt the technical setup each time. Over time, individual data points begin to form a connected system across schools.

For EarthMuseum Learn, the goal is not simply to grow, but to build something that keeps those classrooms connected rather than operating in isolation.

Conclusion

EarthMuseum Learn offers one way to bring environmental learning closer to students’ daily experience.

By combining real-time monitoring with classroom teaching and global data sharing, the program gives students a way to follow air quality through observation, comparison, and discussion. It also suggests a different way of teaching these topics—one where classrooms are connected through shared data and analysis instead of working in isolation.

A severe heatwave is affecting India, Pakistan and Afghanistan, with temperatures exceeding 100°F (38°C) across the region. Learn more about ongoing heat risks and alerts.

","Why is there a heatwave in South Asia? A prolonged heatwave is affecting South Asia, driven by strong high-pressure systems that trap hot air near the surface. Temperatures in India, Pakistan and Afghanistan have soared well above seasonal averages, with some areas approaching or exceeding 45-50 degrees Celsius (113-122 degrees Fahrenheit). The heat arrived earlier than the typical May-June season. High-pressure systems dominate, trapping hot air near the surface like a dome, preventing it from rising and cooling, while sinking air compresses, warms, and blocks clouds, allowing relentless solar heating (1). Climate scientists say meteorological conditions are up to 4°C warmer than in the past, mostly ascribing the increased heat to human-driven climate change. Which cities or areas are affected by the heatwave? Several major cities across South Asia are experiencing extreme heat during this heatwave event, some of the affected include: India: Aheri, Ahmedabad, Agra, Delhi, Dhanbad, Indore, Jaisalmer, Jodhpur, Kota, Macherla, Nagpur, Nanded, Prayagraj, Raipur, Sambalpur and Solapur. Pakistan: Bahawalpur, Dadu, Hyderabad, Lahore, Multan, Rahim Yar Khan, Sahiwal, Sibi, Sukkur and Turbat. Afghanistan: Lashkar Gah and Mirabad. How long will the heatwave last? The heatwave began in early April 2026 and is expected to persist through the summer months. In India, forecasts indicate above-normal heatwave days throughout the April-June period. The India Meteorological Department chief stated there will be an increased number of heatwave conditions along the east coast states and Gujarat by about four to five days into the month of May (2). Pakistan's meteorological department (PMD) has warned of continued heatwave conditions across central and upper Sindh for several days to weeks. This long-term pattern means temperatures will likely remain above 100°F (38°C) throughout the summer season across much of the region, until the monsoon season provides relief (3). In Afghanistan, summer heat typically lasts from May through September, with temperatures in southern regions like Kandahar reaching 36-43°C (97-109°F). It is possible that a strong El Niño projected for this summer may also contribute to more intense, longer-lasting heat waves and dry weather in South Asia (4). Are there any alerts in place? Multiple heat alerts are active across South Asia. In India, several regions in Gujarat were placed under orange alert status, indicating heatwave conditions and heightened probability of heat-related illnesses (5). The Uttar Pradesh Government issued directives for hospitals to prepare for increased cases of heat-related illnesses and alerted veterinarian teams to ensure adequate shelter and water for livestock. The India Meteorological Department continues issuing warnings for severe heatwave conditions in western regions and along the coast. In Pakistan, the PMD forecast continued heatwave conditions and urged citizens to avoid exposure to direct sunlight during daytime and remain hydrated. Both countries have Heat Action Plans coordinated through disaster management authorities (6). Afghanistan's extreme summer heat typically affects outdoor workers and vulnerable populations, though formal heat-specific alert systems are limited compared to neighboring countries.

","Is the air quality good in Santiago? As of May 14, 2026, at 1:30 AM (local time, GMT-4), air quality in Santiago, Chile, has worsened sharply over the past several hours due to a build-up of fine particulate matter combined with poor atmospheric dispersion. The AQI is above 160, classified as \"unhealthy,\" with PM2.5 as the dominant pollutant. These conditions pose serious health risks, particularly for children, the elderly, and those with respiratory or cardiovascular conditions. For a complete, real-time view of current pollution levels, see Santiago’s air quality map. While air quality in Santiago is typically moderate, today’s conditions are very poor, with PM2.5 levels reaching 13 times the WHO annual guideline of 5 µg/m³. By comparison, Santiago’s 2025 annual average PM2.5 concentration was 18.9 µg/m³, equivalent to an AQI of 65. This means today’s pollution levels are 2.5 times than the city’s annual average, underscoring the unusual and alarming intensity of this pollution episode.

What’s in wildfire smoke? Wildfire smoke is a mixture of thousands of individual compounds, including harmful particles and gases that pose a severe health risk to anyone (including pets) nearby and downwind from a fire. Wildfire smoke often contains: water vapor particulate matter trace minerals carbon dioxide carbon monoxide nitrogen oxides hydrocarbons and nitrogen oxide compounds that contribute to elevated ozone (O3) levels volatile organic compounds (VOCs), including acrolein and formaldehyde (potent respiratory irritants) Wildfire smoke often contains fine (PM2.5) and ultrafine particles that can be absorbed directly into your blood stream and reach any organ or area of your body. Pictured: The typical contents of wildfire smoke, including ultrafine particles (≤ 0.3 microns), PM2.5 (2.5-10 microns), acrolein, PM10 (> 10 microns), formaldehyde, carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides, and hydrocarbons. Source: IQAir Wildfire smoke composition depends upon multiple factors, including: the types of wood and vegetation burning the moisture content the fire temperature wind conditions other weather-related influences The primary pollutant threatening the health of those nearby and downwind of a wildfire is particulate matter. Wildfire smoke often contains fine (or PM2.5) and ultrafine particles. These tiny airborne particles are the most dangerous to your health. Fine particles (smaller than 2.5 microns) penetrate deeply into your lungs. The most dangerous are ultrafine particles (smaller than 0.1 microns), which represent 90% of all airborne particles. These particles are tiny and can be absorbed directly into your bloodstream. Once in your blood, they can reach any organ or area of your body. Clean the air with high-performance air filtration Learn more about our wildfire smoke air purifiers Click here Wildfire smoke and at-risk populations Most healthy adults will recover from smoke exposure. However, certain individuals are more at risk for severe health consequences, including:2 Young children. Children whose lungs are still developing are considered more vulnerable, regardless of whether they have a pre-existing condition. Pregnant women. Wildfire smoke inhalation puts pregnant women and their unborn children at a higher risk than the general population. Older adults. This population is at-risk due to an increased rate of pre-existing heart and lung disease. Anyone with a respiratory disease. Individuals with emphysema, chronic bronchitis, COPD, asthma, or another respiratory disease are at-risk. Individuals with heart disease. Circulatory diseases include high blood pressure, vascular diseases, heart failure, and cerebrovascular conditions. These conditions make sufferers susceptible to heart attacks, transient chest pain, heart failure, stroke, and sudden death from cardiac arrhythmia. Young children, pregnant women, older adults, and people with respiratory and cardiovascular pre-existing conditions may find that they experience more severe symptoms and find it harder to breathe.3 The full impact of wildfire smoke is not yet fully understood. A 2017 review in Environmental Toxicology and Pharmacology found that there are still important study opportunities for exploring the long-term health implications of smoke exposure, smoke exposure recovery, and additional smoke inhalation health impacts for children.4 Exposure to smoke can be dangerous simply due to the microorganisms within the smoke. A 2020 study in Science magazine noted that microorganisms, such as bacteria and fungal spores, comprise some of the particulate matter found in smoke.5 The study theorizes that infectious disease may be spread as bacteria and fungi become part of smoke’s particulate composition. Microorganisms, such as bacteria and fungal spores, comprise some of the particulate matter found in smoke, and infectious disease may be spread as they become part of the smoke’s particulate composition. How wildfire smoke behaves Many factors affect wildfire smoke behavior, such as: weather geographical terrain the stage of the fire wind Use the live, interactive air quality map below to see how weather, wind, and location can impact the behavior of wildfire smoke near you. Windy conditions generally cause smoke to mix with larger volumes of air to lower smoke concentrations. However, strong winds also can spread fires more quickly, causing larger fires with greater impact. Regional weather can be the dominant determinant in how a fire behaves as well as how smoke affects surrounding areas. However, regional weather systems can spread fires quickly and result in larger fires with more smoke generated, creating the potential for even greater impacts. Strong regional weather systems can also dominate a fire’s behavior for days and be the determining factor of where and how smoke will affect an area. Smoke can travel for miles beyond its source. In 2020, smoke from wildfires in the Western United States drifted for nearly 5,000 miles, eventually being detected in Europe. Smoke can travel for miles beyond its source. In 2020, smoke from wildfires in the western United States drifted for nearly 5,000 miles, eventually being detected in Europe.6 Wildfire safety tips Wildfire smoke events can occur seemingly without warning. But there are steps you can take to prepare yourself using appropriate safety precautions for wildfires. Keep the air clean in your home. Keep windows and doors closed closed and seal off any openings to the outside, including vents, to help prevent outdoor smoke from getting in. When using an air conditioner, be sure to set it to re-circulate and close the fresh-air intake. Filter the air when ventilating the space. An air purifier for wildfire smoke, will help remove smoke particles of all sizes down to 0.003 microns from the indoor air and help control ozone levels. This is critical if you live in an urban area downwind (even remotely) from wildfires. Stay indoors as much as possible. This tactic is most useful in buildings that effectively stop outdoor air from getting inside. If you need to travel by car to leave or evacuate an area affected by wildfire smoke, use a car air purifier to help keep your vehicle interior air clean as you pass through smoky or polluted areas. You can also use a portable, personal air purifier to access clean air where other air filtration systems are not available. Wear a mask outdoors. Only use an air pollution mask with an N95, KN95, N100, or FFP2 rating to help. Avoid activities that further pollute the indoor air. Avoid burning candles, using the fireplace, or even vacuuming unless you own a high-performance HEPA vacuum cleaner. All of these activities can otherwise become additional sources of indoor air pollutants. Monitor your indoor air quality. Use an air quality monitor to track levels of indoor pollutants like PM2.5 and CO2 from smoke and other indoor pollution sources. Take action if indoor air pollutants rise to dangerous levels by running an air purifier, circulating fresh air through your HVAC system, or leaving your home temporarily if indoor air becomes unsafe to breathe or your home is threatened by wildfire. Use an air quality monitoring app to keep track of pollutants in your environment. The AirVisual app displays real-time hyperlocal data from over 80,000 sensors around the world. The app also tracks up to six key wildfire pollutants, such as PM2.5, CO2, and NO2, so that you have the best picture of your local air quality during a wildfire and can take action to help protect your health. Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. Learn to protect the health of yourself and your family, and rest assured that you’ve taken the necessary precautions. During a wildfire, it’s also important to monitor your local air quality to see how wildfire smoke will affect your outdoor air. The takeaway Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. And while wildfire smoke may be a warning sign of imminent fires, smoke also delivers its own set of risks for people living miles beyond the source. Though smoke pollutants carried on the wind may be invisible, their impacts are felt by those most at risk. Smoke pollutants pose health threats that range from irritation and cough to more serious respiratory and cardiac risks. By helping control smoke pollutants that threaten our indoor air quality through monitoring and air purification, it's possible to help manage wildfire smoke health risks.","

The primary pollutant threatening the health of those nearby and downwind of a wildfire is particulate matter. Wildfire smoke often contains fine (or PM2.5) and ultrafine particles. These tiny airborne particles are the most dangerous to your health.

Fine particles (smaller than 2.5 microns) penetrate deeply into your lungs.

The most dangerous are ultrafine particles (smaller than 0.1 microns), which represent 90% of all airborne particles. These particles are tiny and can be absorbed directly into your bloodstream. Once in your blood, they can reach any organ or area of your body.

Wildfire smoke and at-risk populations

Most healthy adults will recover from smoke exposure. However, certain individuals are more at risk for severe health consequences, including:²

\n
Young children. Children whose lungs are still developing are considered more vulnerable, regardless of whether they have a pre-existing condition.
\n
\n
Pregnant women. Wildfire smoke inhalation puts pregnant women and their unborn children at a higher risk than the general population.
\n
\n
Older adults. This population is at-risk due to an increased rate of pre-existing heart and lung disease.
\n
\n
Anyone with a respiratory disease. Individuals with emphysema, chronic bronchitis, COPD, asthma, or another respiratory disease are at-risk.
\n
\n
Individuals with heart disease. Circulatory diseases include high blood pressure, vascular diseases, heart failure, and cerebrovascular conditions. These conditions make sufferers susceptible to heart attacks, transient chest pain, heart failure, stroke, and sudden death from cardiac arrhythmia.
\n

Young children, pregnant women, older adults, and people with respiratory and cardiovascular pre-existing conditions may find that they experience more severe symptoms and find it harder to breathe.³

The full impact of wildfire smoke is not yet fully understood. A 2017 review in Environmental Toxicology and Pharmacology found that there are still important study opportunities for exploring the long-term health implications of smoke exposure, smoke exposure recovery, and additional smoke inhalation health impacts for children.⁴

Exposure to smoke can be dangerous simply due to the microorganisms within the smoke. A 2020 study in Science magazine noted that microorganisms, such as bacteria and fungal spores, comprise some of the particulate matter found in smoke.⁵ The study theorizes that infectious disease may be spread as bacteria and fungi become part of smoke’s particulate composition.

How wildfire smoke behaves

Many factors affect wildfire smoke behavior, such as:

\n
weather
\n
\n
geographical terrain
\n
\n
the stage of the fire
\n
\n
wind
\n

Use the live, interactive air quality map below to see how weather, wind, and location can impact the behavior of wildfire smoke near you.

$\"placeholder$

Windy conditions generally cause smoke to mix with larger volumes of air to lower smoke concentrations. However, strong winds also can spread fires more quickly, causing larger fires with greater impact.

Regional weather can be the dominant determinant in how a fire behaves as well as how smoke affects surrounding areas. However, regional weather systems can spread fires quickly and result in larger fires with more smoke generated, creating the potential for even greater impacts.

Strong regional weather systems can also dominate a fire’s behavior for days and be the determining factor of where and how smoke will affect an area.

Smoke can travel for miles beyond its source. In 2020, smoke from wildfires in the Western United States drifted for nearly 5,000 miles, eventually being detected in Europe.

Wildfire safety tips

Wildfire smoke events can occur seemingly without warning. But there are steps you can take to prepare yourself using appropriate safety precautions for wildfires.

\n
Keep the air clean in your home. Keep windows and doors closed closed and seal off any openings to the outside, including vents, to help prevent outdoor smoke from getting in. When using an air conditioner, be sure to set it to re-circulate and close the fresh-air intake. Filter the air when ventilating the space. An air purifier for wildfire smoke, will help remove smoke particles of all sizes down to 0.003 microns from the indoor air and help control ozone levels. This is critical if you live in an urban area downwind (even remotely) from wildfires.
\n
\n
Stay indoors as much as possible. This tactic is most useful in buildings that effectively stop outdoor air from getting inside. If you need to travel by car to leave or evacuate an area affected by wildfire smoke, use a car air purifier to help keep your vehicle interior air clean as you pass through smoky or polluted areas. You can also use a portable, personal air purifier to access clean air where other air filtration systems are not available.
\n
\n
Wear a mask outdoors. Only use an air pollution mask with an N95, KN95, N100, or FFP2 rating to help.
\n
\n
Avoid activities that further pollute the indoor air. Avoid burning candles, using the fireplace, or even vacuuming unless you own a high-performance HEPA vacuum cleaner. All of these activities can otherwise become additional sources of indoor air pollutants.
\n
\n
Monitor your indoor air quality. Use an air quality monitor to track levels of indoor pollutants like PM2.5 and CO₂ from smoke and other indoor pollution sources. Take action if indoor air pollutants rise to dangerous levels by running an air purifier, circulating fresh air through your HVAC system, or leaving your home temporarily if indoor air becomes unsafe to breathe or your home is threatened by wildfire.
\n
\n
Use an air quality monitoring app to keep track of pollutants in your environment. The AirVisual app displays real-time hyperlocal data from over 80,000 sensors around the world. The app also tracks up to six key wildfire pollutants, such as PM2.5, CO₂, and NO₂, so that you have the best picture of your local air quality during a wildfire and can take action to help protect your health.

Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. Learn to protect the health of yourself and your family, and rest assured that you’ve taken the necessary precautions.

During a wildfire, it’s also important to monitor your local air quality to see how wildfire smoke will affect your outdoor air.

The takeaway

Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. And while wildfire smoke may be a warning sign of imminent fires, smoke also delivers its own set of risks for people living miles beyond the source.

Though smoke pollutants carried on the wind may be invisible, their impacts are felt by those most at risk. Smoke pollutants pose health threats that range from irritation and cough to more serious respiratory and cardiac risks.

By helping control smoke pollutants that threaten our indoor air quality through monitoring and air purification, it's possible to help manage wildfire smoke health risks.

Let's look more critically at air purification.","The home air purifier market has undergone many shifts and starts in its decades-long history as an affordable solution for indoor air quality. Along with those shifts have been seemingly ground breaking advancements in filtration technologies that may seem like the next revolution in air purification. But not all air purifiers safely clean the air. Not all air purifiers safely clean the air. Let's take an evidence-based approach to the industry and separate the fact from the fiction. What should I look for in an air purifier? Before we examine the various air purifiers on the market with a critical eye, it’s essential to have a solid understanding of what does make a good air purifier. 1. HEPA filters are the standard for the industry. What is a HEPA filter? High-efficiency particulate air (HEPA) filters capture airborne particles from moving air using a dense, random arrangement of fibers. HEPA filters use the physics of particles moving through air to yank them out of the air flow. Their operation is simple but extremely effective, and HEPA filters are now standard issue for almost every air purifier on the market. But it wasn’t always that way. Air purifiers have been around for well over a century. The first air purification systems appeared in the 1850s in charcoal-based masks used by coal miners. They were designed to keep toxic dust out of their lungs. The technology was so successful that, less than twenty years later, respirators were added to these types of masks to protect firefighters from breathing in smoke chemicals and pollutants (1). Beginning in the 1940s, the United States Atomic Energy Commission started experimenting with high-efficiency particulate arrestance, better known now as HEPA, as a method of shielding soldiers from atomic radiation on World War II battlefields (2). HEPA filters did nothing to filter radiation particles, but researchers quickly learned that HEPA filters could filter out many harmful pollutants. In 1963, Manfred and Klaus Hammes, the founders of IQAir, introduced the world’s first residential air filter based on HEPA technology, helping reduce indoor pollution as well as chronic asthma symptoms. Not long after, HEPA became so widespread that the U.S. Department of Energy (DOE) required that all filters sold under the name “HEPA” must filter at least 99.97% of airborne particles down to 0.3 microns (3). Since then, HEPA air purification has become the standard for the air purification industry. HEPA is now thrown around as a generic term for air filters, but HEPA filters continue to filter 99.97% of particles down to 0.3 microns. The HyperHEPA filter builds upon the HEPA model to create even more efficient filtration systems. Many manufacturers, including IQAir, have built upon the HEPA model to create even more efficient filtration systems. IQAir’s patented HyperHEPAfilter is one such filter. HyperHEPA filters remove 99.5% of particles down to 0.003 microns, which are 100 times smaller than the DOE’s required 0.3-micron particle size. 2. Not all air purifier designs are created equal. All air purifier manufacturers know that their filters need to live up to this HEPA standard. But long-standing, strict guidelines around air filters can provide a false sense of security in HEPA. To advertise an air purifier as HEPA, it only needs to contain HEPA paper, the paper used to construct a HEPA filter. Whether the air purifier’s Total System Efficiency meets HEPA requirements is another story. In fact, most HEPA air purifiers are not tested for total efficiency (4). The hidden factor at work here is leakage. Despite the high efficiency of many HEPA filters, the housing designs of many air purifiers are not airtight. This means that dirty, unfiltered air passes around the HEPA filter through tiny openings, cracks, and space around the frame of the HEPA filter itself or between the frame and the purifier housing (5). So even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, they’re only telling part of the story. In some cases, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less (6). Even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less. Some air purifier manufacturers have resolved this issue with designs that are built to minimize or eliminate leakage. IQAir uses patented 3D UltraSeal knife-edge-in-groove sealing between the filter frame and the purifier housing to guarantee the full efficiency of our HyperHEPA filtration media. 3. Concerned about gas and odors? Go beyond HEPA. While HyperHEPA filters are great at getting particles out of the air, they do NOT take gases and odors out of the air. Unlike particles, the molecules that comprise gases, odors, and volatile organic compounds (VOCs) are not solid and will float through even the densest HyperHEPA filters. That’s where activated carbon filters come in. How do these filters work? It’s simpler than you might think: Chunks of carbon material (like charcoal) are exposed to high concentrations of oxygen. Countless pores open on the carbon surface, increasing the carbon surface area enormously. At this point, a pound of activated carbon can have the same surface area as 100 football fields. Several pounds of activated carbon are arranged in a flat “bed” and packaged in a proprietary filter design (such as IQAir’s V5 Cell gas and odor control filter). Air passes through the activated carbon bed. Gas, chemical, and VOC molecules are adsorbed into the carbon pores, meaning that they chemically bond to the extensive charcoal surface area. Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes (7)(8). Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes. Some air purifiers are designed to maximize activated carbon in case you’re more concerned about, for example, gases from cooking or odors from pets than about particle pollution in your home. IQAir’s GC MultiGas is built for such a purpose—while carbon filters generally use a few pounds of carbon, the GC MultiGas contains 12 pounds of activated carbon as well as impregnated alumina, providing well over 1200 football fields worth of surface area for gas and VOC molecules to adsorb to. The takeaway Now you know that the elements of a good air purifier are: HyperHEPA media for particle filtration No system leakage due to sealed filter and purifier housing Activated carbon for gas and odor filtration But we're not done yet. Just as important to know is what not to look for in an air purifier. What should I avoid in an air purifier? When considering air purifiers, some people wonder about their effectiveness and even potential risks. Question often arise, such as \"Do air purifiers work?\" or \"Are air purifiers effective?\" The answer is that while some air cleaning methods can remove particles and pollutants from the air, their capabilities are often limited. But it's not just about effectiveness. People also ask, \"Are air purifiers bad for you?\" This concern arises from potential hidden costs to your health. It's important to be aware of inefficiencies and any potential risks associated with the air purifier you're considering before making a purchase. So, if you're in the market for an air purifier, remember to ask yourself whether it will be effective at removing pollutants and particles from the air, and whether it poses any risks to your health. Ionizer air purifiers Ionizers are purported to purify air by sending out negatively charged ions (anions) that attract positively charged pollution particles (cations), causing them to leave the air and stick to surfaces like ceilings, walls, and furniture. Many popular air purifiers use ionization technology, also called negative ionization, as a central component of their operation. Research suggests that ionizers can help stop potentially infectious molds and bacteria from spreading in sterile environments like dental clinics and hospitals (9)(10). But there are two critical downsides to ionization (11)(12): Ionizer air purifiersdon’t get rid of pollutants. Particles charged by negative ions aren’t removed from the air—they merely stick to surfaces nearby. This includes surfaces inside your airways, such as your windpipe and alveoli, the sacs of air in your lungs. Pollutant build-up can cause heart, lung, and other respiratory conditions. Ionizer air purifierscan generate harmful ozone. Ionizers produce ozone (O3) that can build up to dangerous levels indoors. At even low levels, indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb (the organ that helps your brain process odors), and even be fatal at high concentrations. Indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb, and even be fatal at high concentrations. Verdict Don't buy an ionizer air purifier.They don’t remove particles from the air, and the ozone they produce can have harmful side effects, even if the purifier claims that they only charge the particles “a little bit.” Ozone Generators It’s worth saying again: ozone is TERRIBLE for you, especially indoor ozone build-up. The health concerns are serious enough that in 2017, California banned the use of ozonehome air purifiers (13). Ozone generators use a process called corona discharge to release ozone molecules into the air. When an ozone molecule intermingles with a particle or gas molecule, an ozone atom clings to the other molecule and blows it up in a process known as oxidation. Oxidation in the atmosphere after a lightning strike is also what makes the air smell so distinct after a thunderstorm. However, ozone generators do little to clean air and are quite bad for you. Here’s just a short (and far from complete) list of reasons why (14)(15)(16)(17)(18): Ozone can take years to fully clear even a small room of gases. Ozone reactions can introduce ultrafine particles (UFPs) into the air.UFPs can get into your lungs and your bloodstream, causing heart disease and even stunting lung development in children. Indoor ozone levels can rise five to ten times above recommended limits,which range from 0.05 to 0.1 parts per million (ppm), because of a lack of ventilation and in combination with outdoor ozone that seeps indoors.To put this in perspective, those who are sensitive to ozone, such as children, people with asthma, and pets, start experiencing health effects at only 0.01 ppm. Even a “safe” ozone generator that emits a small amount of ozone can quickly trigger potentially life-threatening ailments like asthma attacks. Verdict Don’t buy an ozone generator. They’re NOT air purifiers. Not only do they fail to clean your air, they hurt you and the most vulnerable in your home: your children and your pets. UV Light Purifiers Ultraviolet (UV) light is often used to disinfect equipment in hospitals and prevent the spread of harmful strains of bacteria and viruses (19)(20). One of the most common UV purification methods is called ultraviolet germicidal irradiation, or UVGI. In UVGI, intense UV lights are shined on bacteria and viruses, damaging their DNA beyond repair. Bacterial cells and viruses then shut themselves down because they can no longer function. This is called apoptosis, or programmed cell death, which effectively destroys their ability to cause infections (21). But UV air purification isn’t all it’s cracked up to be. Here’s why(22) (23) (24) (25) (26): Bacteria and viruses need to be exposed to UV light for a certain amount of timebefore they’re rendered harmless: some strains need to be treated with UV for several hours in direct UV light before they’re destroyed.Home UV air purifiers don’t shine UV light on them long enough to be genuinely useful. Some bacteria can come back to life and become infectious again even after being disinfected by UV light. UV lights do nothing for pollutant particles.Air treated with UV light can still be full of harmful particulate matter, like PM10 and PM2.5. Many UV air purifiers produce ozone. UV light can burn your skin and damage your eyes. Sure, most UV purifiers block the light from shining out of the purifier, but even brief UV exposure can cause permanent skin and eye damage as well as cancer. Air treated with UV light can still be full of harmful particulate matter. Verdict Don’t buy a UV light air purifier. UV light somewhat disinfects but doesn’t purify air, and research shows that UV’s disinfection potential for air may be exaggerated. What do I do now? At this point, you should feel like you have a good sense of what’s fact and what’s fiction when it comes to a truly effective air purification system. So, what should you do now, armed with your knowledge of what makes a good air purifier? You have a multitude of options for maximizing your indoor air quality: Get a HyperHEPA air purifier.

But UV air purification isn’t all it’s cracked up to be. Here’s why(22) (23) (24) (25) (26):

\nBacteria and viruses need to be exposed to UV light for a certain amount of timebefore they’re rendered harmless: some strains need to be treated with UV for several hours in direct UV light before they’re destroyed.Home UV air purifiers don’t shine UV light on them long enough to be genuinely useful.
\nSome bacteria can come back to life and become infectious again even after being disinfected by UV light.
\nUV lights do nothing for pollutant particles.Air treated with UV light can still be full of harmful particulate matter, like PM10 and PM2.5.
Many UV air purifiers produce ozone.
\nUV light can burn your skin and damage your eyes. Sure, most UV purifiers block the light from shining out of the purifier, but even brief UV exposure can cause permanent skin and eye damage as well as cancer.

Air treated with UV light can still be full of harmful particulate matter.

Verdict

Don’t buy a UV light air purifier. UV light somewhat disinfects but doesn’t purify air, and research shows that UV’s disinfection potential for air may be exaggerated.

Himalayan salt lamps DO NOT purify indoor air.

These trendy little lamps consist of a light bulb placed inside a chunk of pink Himalayan salt. They’re easily recognized by their hand-carved, often stylized shapes and dim, pinkish glow they emit when light shines through them.

They’ve been gaining popularity for years, mostly because their distinct color and unique appearance make them attractive objects for interior decoration, and their glow can add a pleasing atmosphere to a room.

But their recent rise in popularity as “natural” air purifiers should trouble you.

A host of (often misleading) studies supporting the use of salt in treating respiratory conditions have escalated demand for these little pink things, especially within the well-primed alternative medicine market, full of people who may already be seeking home remedies for all sorts of health conditions and indoor environmental issues when modern medicine hasn’t seemed to help.

And you shouldn’t buy a Himalayan salt lamp to purify your air for one major reason: they’re negative ionizers, and negative ionization is one of the most absurd air purification myths ever devised.

Why are Himalayan salt lamps bad for air quality?

Again, two words: negative ionization.

If you ever hear the words “ionization” (in one form or another) and “air purification” in the same sentence, you should run in the opposite direction.

In the context of air purification, negative ionization happens when negatively charged particles attach themselves, or “charge,” pollutant particles in the air, effectively removing them from ambient air by causing them to stick to nearby surfaces.

This phenomenon also occurs in nature – know that distinct smell in the air after a thunderstorm? That’s the result of “atmospheric space charge” as air ions are generated by the electric fields of storms.¹ Many air purifiers and purification devices sold in stores, including Himalayan salt lamps and a variety of “air ionizers,” artificially produce high voltage to achieve this same effect.

The problem with negative ionization, though, is that it doesn’t actually remove pollutants from your indoor air – it just causes the particles to adhere themselves to nearby surfaces, where they’re easily stirred up by indoor activities like dusting, vacuuming, and ventilation.

Charged particles can also stick to your respiratory tract, where charged particles can settle in your windpipe and lungs and cause even more harm that if they’d just remained in the air. Studies show that these particles can penetrate deep into your respiratory system and cause both heart and lung conditions.²

The average, nightstand-sized Himalayan salt lamp generates only a small number of negative ions into the air, so you may not notice any tangible change in your air quality or health, at least immediately. But these lamps can be huge: you can buy salt lamps that weight up to 300 pounds for thousands of dollars, and their ionization effects may have a more noticeable effect on your air, especially if you live in an airtight, energy-efficient home in which indoor pollutants have a much harder time getting out.

And negative ionizers have another dark secret: they can also create indoor ozone (O₃).

There are two main types of ozone:

\nStratospheric ozone: Alayer of ozone occurs naturally several miles up in the atmosphere, where it protects the surface of the earth (and people’s skin) from ultraviolet (UV) radiation from the sun.
\nTropospheric ozone: Also called ground-level ozone or smog, ground-level ozone tends to develop when heat from sunlight reacts with chemicals near the ground, many of which are produced by emissions from vehicle exhaust and factory smoke.

Further research suggests that ozone is also responsible for long-term health problems, such as asthma, heart disease, and lung disease. Emerging studies on rats also suggest that ozone could cause seizures and blindness.

So even though you may not get rush-hour levels of ozone in your home from a salt lamp, indoor ozone buildup can indeed cause some disruptive health effects if you don’t follow best practices for good Indoor Air Quality.

So what’s so special about Himalayan salt?

So how did someone come up with the idea that Himalayan salt lamps have any health effects at all?

The story stretches back millennia. Truly authentic Himalayan salt comes from the Khewra salt reserves in the Punjab region of Pakistan. Salt mined here is thought to be millions of years old and contain numerous minerals.

Salt lamps have been proposed for use in treatments for conditions like chronic obstructive pulmonary disease (COPD) because of their purported therapeutic effects on your respiratory system.

Stable air temperature
Moderate to high humidity

Lack of airborne pollutants

Halotherapy takes the notion that salt cave environments are good for respiratory health by having people inhale small amounts of salt particles that are released into the ambient air of a controlled room to “reproduce” a salt cave’s microclimate.

Are scented candles bad for you?

Burning a scented candle is a popular way to create a pleasant ambiance at home. Scents such aslavender, jasmine, and sandalwood can be relaxing and invigorating. During the holidays, many people find the warm glow and aroma of pine, gingerbread, or cinnamon makes a room feel more festive.

Unfortunately, most mass-produced scented candles can have a negative impact on indoor air quality. From the wax to the wick to the fragrance itself, the average scented candle can release harmful chemicals into the air — even when unlit.

From the wax to the wick to the fragrance itself, the average scented candle can release harmful chemicals into the air — even when unlit.

So while you and your family may enjoy the fragrance of scented candles in your home, they may be harmful to your health. Read on to learn why some candles are bad for you.

Paraffin wax

Are paraffin wax candles safe? In what way can wax be harmful?

According to a 2017 study in the International Journal of Tropical Disease and Health, paraffin candles emit pollutants that can threaten human health and shouldn’t be burned in enclosed areas (1).

Most candles are made from paraffin, a petroleum byproduct. To create paraffin wax candles, petroleum waste is chemically bleached, deodorized, and made into wax. When burned, paraffin wax can release toxicvolatile organic compounds (VOCs) into the air, including known carcinogens like:

alkenes
acetone
benzene
toluene

These are the same chemicals found in diesel fuel emissions and are known to cause allergies, asthma attacks, and skin problems.

A 2005 study published by the University of South Florida showed that candles made of paraffin wax emit low levels of benzene even when they are not lit (2).

Is burning candles bad for you?

In addition to releasing toxic chemicals, burning paraffin wax produces soot composed of particulate matter such as, PM2.5 and ultrafine particles that can remain suspended in the air for hours. According to the University of South Florida study, ultrafine soot particles are similar to diesel exhaust in both their size and composition. They penetrate deeply into the lungs and are absorbed into the blood stream (3).

A 2000 study conducted by the U.S. Environmental Protection Agency showed that soot emissions from candles are significantly higher after wax breakthrough occurs and when a candle is smoldering (4).

Ultrafine particles are associated with severe health issues, including:

allergies
asthma
COPD (5)
respiratory tract infections
heart attacks
strokes
cancer

So, are candles bad for your health? Not all candles produce the same amount of air pollutants. A 2002 study published in theJournal of the American Oil Chemists’ Society found that soywax, much like beeswax candles, burned at a significantly lower rate and resulted in less soot than paraffin candles (6).

Chemical fragrances

Another problem with scented candles is that the chemicals they use to create a pleasing aroma are generally far from wholesome.

Most scented candles use synthetic fragrances and dyes that give off dangerous VOCs even at room temperature.

Most scented candles use synthetic fragrances and dyes that give off dangerous VOCs even at room temperature. Commonly emitted VOCs related to the scent in candles include (7):

formaldehyde
petroleum distillates
limonene
alcohol
esters

These harmful chemicals can cause health problems, such as:

headaches
dizziness
allergy symptoms
asthma attacks
respiratory tract infections
cancer
\n\n\t

Cored wicks

Many candles have cored wicks made from cotton that are wrapped around a metal support. The design helps keep the wick from falling over into the wax. This is especially useful for scented candles because the fragrance oils soften the wax and allow non-cored wicks to go limp.

Are candles toxic? If they have lead in them, possibly. Lead was once commonly used in cored candlewicks — especially in candles imported from overseas. However, after determining that these wicks could present a lead poisoning hazard to young children, the U.S. Consumer Product Safety Commission banned the manufacture and sale of all candles with lead-core wicks in 2003 (8). Zinc and tin have been used as a substitute since the ban.

All metal-core wicks release trace amounts of heavy metals into the air when they are burned.

However, all metal-core wicks release trace amounts of heavy metals into the air when they are burned. Wicks with zinc and tin cores can still release small amounts of lead particles (9,10).

Safer alternatives

To limit soot stains and poor air quality in your home, you should avoid or restrict the use of candles (11).

If you still crave the pleasant ambiance and aroma of scented candles, here are safer ways to scent the air:

\nUse essential oils for fragrance.Essential oils can be placed in a diffuser or in bathwater to create a desired aroma.
\nSimmer spices.Place spices such as cinnamon sticks, cloves, and nutmeg in a pot of water and let it simmer on the stove.
\nCreate potpourri.Dried items such as flowers, berries, fruit rinds, wood chips, and spices can be placed in bowls or fabric bags and placed around your home.

The takeaway

Lighting scented candles may seem like a relaxing way to enjoy your home. But burning scented candles releases VOC pollutants and worsens your home’s indoor air quality. Although fragrances from safer alternatives like essential oils can be pleasant, trulyclean air smells like nothing at all.

With a professional foundation in electrical engineering and a passion for environmental stewardship, Mwendwa's deployment of a low-cost air quality sensor in Kenya’s capital city, Nairobi, marks a pivotal step in revealing and addressing pollution and bridging critical gaps in Africa’s air quality data. Nairobi's leap towards cleaner air In late 2021, Mwendwa established an air quality station. Set up along one of Nairobi’s busy thoroughfares, the station gathers data on pollutants from sources like vehicular exhaust and biomass burning. \"It's about leveraging technology to unveil the hidden dangers of pollution.” “It's about leveraging technology to unveil the hidden dangers of pollution,” Mwendwa said. “Empowering our community with this data is crucial for driving action and advocating for sustainable solutions. Without data, we remain in the dark.” Local expertise, global resources drive innovation Building on the foundation of community-driven air monitoring, the project has taken a step forward. It now hosts East Africa’s first Monster Aerosol System (a platform that houses advanced aerosol analyzers), featuring a Time-of-Flight Aerosol Chemical Speciation Monitor (TOF-ACSM). This technology provides real-time, high-resolution data on airborne particles—including nitrates, ammonium, and chlorides—uncovering the chemical fingerprints of pollution with unprecedented precision. Paired with a black carbon monitor, the system offers a comprehensive view of airborne composition and sources. These reference-grade instruments build on the project’s original IQAir AirVisual Outdoor monitor—pairing community-level, real-time data with laboratory-grade chemical insight.

Learn about Permian Health's innovative approach to improving air quality in Gambia, using cutting-edge technology to reveal invisible pollutants and safeguard public health.

","In the slender West African nation of Gambia, Dr. Sunkaru Touray of Permian Health Lung Institute is leading an unprecedented initiative to illuminate the invisible dangers of air pollution through the strategic deployment of low-cost air quality monitors. A vision born from necessity Dr. Touray, a pulmonologist and critical care physician originally from Kartong, The Gambia, was profoundly affected by the respiratory issues he encountered while practicing in New Mexico. These issues, often linked to hydrocarbon exposure and environmental pollutants, spurred him to address similar problems in Gambia, where air quality data is scarce. \"There's a significant data gap in Africa when it comes to understanding our air,\" Dr. Touray noted. Recognizing the parallels between New Mexico and Gambia, Dr. Touray envisioned the Permian Health Clean Air Initiative. This initiative aims not only to collect data but to empower Gambians with knowledge, enabling them to make informed decisions about their health and advocate for cleaner air. “There’s a significant data gap in Africa when it comes to understanding our air.”–Dr. Sunkaru Touray, Founder, Permian Health The journey of Permian Health Permian Health's mission is clear: to democratize access to air quality data in Gambia by installing low-cost air quality monitors throughout the country. The team selected IQAir’s AirVisual outdoor monitors for this critical work. “These devices are proven to be reliable, user-friendly, and can operate on solar power,” Dr. Touray said. “They also have 4G LTE connectivity,” which make the monitors ideally suited for Gambia's diverse environments—from the bustling streets of Banjul to the rural countryside. \"The goal,\" Dr. Touray explained, \"is not just to collect data but to empower our communities with knowledge so they can make informed decisions about their health and advocate for cleaner air.\" Highlighting areas of concern: Brikama’s air quality Brikama stands as a poignant example of the challenges faced across Gambia. Known for its bustling markets and as a hub for both commerce and community life, the town also grapples with air quality issues that pose risks to its residents. By placing monitors in strategic locations, including the busy highway through Brikama, Permian Health is mapping pollution levels and raising awareness among the local population about the air they breathe daily—while simultaneously acting as a testament to the potential of grassroots air monitoring networks in challenging regions. Dr Touray said, \"As we look to the future, the lessons learned from Brikama will inform our expansion strategies to other regions facing similar challenges. Our success in achieving nationwide coverage, with Brikama as a keystone in our network, exemplifies the scalable model of Permian Health Clean Air Initiative.” “The goal is not to just collect the data but to empower our communities with knowledge so they can make informed decisions about their health.” Local feedback has been largely positive. According to Dr. Touray, real-time access to air quality monitor information has improved local understanding of the dangers of poor air quality, especially during the dry, dusty Harmattan season typically experienced from November to March. Permian Health has collaborated with local groups such as the Brikama Nema Diaspora Group (BRIND) and Karamie’s Health clinic to install sensors in key areas, allowing residents and medical professionals to access real-time air quality data. Pioneering work on the ground To date, the Permian Health air quality network has grown to 14 sensors, achieving nationwide coverage with an air quality sensor in all regions of The Gambia—proof of the project's rapid scalability and success. The project has successfully installed air quality monitors in various locations, including urban areas and industrial sites. These monitors provide real-time data on pollutants like PM2.5, which pose the greatest threat to human health, offering invaluable insights into the air pollution across different regions of Gambia. \"We have sensors in the most densely populated areas,” Dr. Touray said. \"Through the process of collecting PM 2.5 data in Gambia and identifying pollution hotspots, we educate the public about air quality and its impact on public health—and also communicate the importance of installing air quality sensors as a means to make a change.\" This foundational work sets the stage for enhanced accuracy and credibility in air quality monitoring, as underscored by a pivotal development in the project's journey. “The recent addition of a reference-grade monitor donated by MetOne marks a significant leap in our capacity for precision and validation of the data collected by our existing sensor network,” Dr. Touray said. However, maintaining and expanding the network can be impeded by dust accumulation on solar panels during the Harmattan season, unreliable power supplies, and other issues. ‘While we have made significant progress in addressing some of these challenges, connectivity and maintenance in remote areas remain ongoing hurdles in our efforts to maintain and expand the sensor network efficiently,’ Dr. Touray explained. Uniting minds and garnering accolades To raise awareness about their work, Permian Health has created a promotional video which serves as a powerful tool to inform and engage the public about their project. A key milestone for the project was the establishment of the first air quality conference in Gambia, bringing together stakeholders from the government, academia, and civil society to discuss the findings and implications of the collected data. \"This conference was a pivotal moment for us, marking the beginning of a national conversation on air quality,\" reflects Dr. Touray.

In the slender West African nation of Gambia, Dr. Sunkaru Touray of Permian Health Lung Institute is leading an unprecedented initiative to illuminate the invisible dangers of air pollution through the strategic deployment of low-cost air quality monitors.

A vision born from necessity

Dr. Touray, a pulmonologist and critical care physician originally from Kartong, The Gambia, was profoundly affected by the respiratory issues he encountered while practicing in New Mexico. These issues, often linked to hydrocarbon exposure and environmental pollutants, spurred him to address similar problems in Gambia, where air quality data is scarce. \"There's a significant data gap in Africa when it comes to understanding our air,\" Dr. Touray noted.

Recognizing the parallels between New Mexico and Gambia, Dr. Touray envisioned the Permian Health Clean Air Initiative. This initiative aims not only to collect data but to empower Gambians with knowledge, enabling them to make informed decisions about their health and advocate for cleaner air.

“There’s a significant data gap in Africa when it comes to understanding our air.”

–Dr. Sunkaru Touray, Founder, Permian Health

The journey of Permian Health

Permian Health's mission is clear: to democratize access to air quality data in Gambia by installing low-cost air quality monitors throughout the country. The team selected IQAir’s AirVisual outdoor monitors for this critical work. “These devices are proven to be reliable, user-friendly, and can operate on solar power,” Dr. Touray said. “They also have 4G LTE connectivity,” which make the monitors ideally suited for Gambia's diverse environments—from the bustling streets of Banjul to the rural countryside.

\"The goal,\" Dr. Touray explained, \"is not just to collect data but to empower our communities with knowledge so they can make informed decisions about their health and advocate for cleaner air.\"

\nHighlighting areas of concern: Brikama’s air quality\n

Brikama stands as a poignant example of the challenges faced across Gambia. Known for its bustling markets and as a hub for both commerce and community life, the town also grapples with air quality issues that pose risks to its residents. By placing monitors in strategic locations, including the busy highway through Brikama, Permian Health is mapping pollution levels and raising awareness among the local population about the air they breathe daily—while simultaneously acting as a testament to the potential of grassroots air monitoring networks in challenging regions.

$\"\"$

Dr Touray said, \"As we look to the future, the lessons learned from Brikama will inform our expansion strategies to other regions facing similar challenges. Our success in achieving nationwide coverage, with Brikama as a keystone in our network, exemplifies the scalable model of Permian Health Clean Air Initiative.”

“The goal is not to just collect the data but to empower our communities with knowledge so they can make informed decisions about their health.”

Local feedback has been largely positive. According to Dr. Touray, real-time access to air quality monitor information has improved local understanding of the dangers of poor air quality, especially during the dry, dusty Harmattan season typically experienced from November to March.

Permian Health has collaborated with local groups such as the Brikama Nema Diaspora Group (BRIND) and Karamie’s Health clinic to install sensors in key areas, allowing residents and medical professionals to access real-time air quality data.

Pioneering work on the ground

To date, the Permian Health air quality network has grown to 14 sensors, achieving nationwide coverage with an air quality sensor in all regions of The Gambia—proof of the project's rapid scalability and success. The project has successfully installed air quality monitors in various locations, including urban areas and industrial sites. These monitors provide real-time data on pollutants like PM2.5, which pose the greatest threat to human health, offering invaluable insights into the air pollution across different regions of Gambia.

\"We have sensors in the most densely populated areas,” Dr. Touray said. \"Through the process of collecting PM 2.5 data in Gambia and identifying pollution hotspots, we educate the public about air quality and its impact on public health—and also communicate the importance of installing air quality sensors as a means to make a change.\"

This foundational work sets the stage for enhanced accuracy and credibility in air quality monitoring, as underscored by a pivotal development in the project's journey. “The recent addition of a reference-grade monitor donated by MetOne marks a significant leap in our capacity for precision and validation of the data collected by our existing sensor network,” Dr. Touray said.

However, maintaining and expanding the network can be impeded by dust accumulation on solar panels during the Harmattan season, unreliable power supplies, and other issues.

‘While we have made significant progress in addressing some of these challenges, connectivity and maintenance in remote areas remain ongoing hurdles in our efforts to maintain and expand the sensor network efficiently,’ Dr. Touray explained.

Uniting minds and garnering accolades

To raise awareness about their work, Permian Health has created a promotional video which serves as a powerful tool to inform and engage the public about their project.

A key milestone for the project was the establishment of the first air quality conference in Gambia, bringing together stakeholders from the government, academia, and civil society to discuss the findings and implications of the collected data.

\"This conference was a pivotal moment for us, marking the beginning of a national conversation on air quality,\" reflects Dr. Touray.

","Nestled in a small town near Cornwall, Canada, Tiny but Mighty Kitten Rescue serves as a lifeline for abandoned and vulnerable kittens (1). For nearly eight years, rescue founder Mellissa has worked tirelessly to save and nurture the most fragile feline lives in the region. Yet despite Mellissa’s dedication to maintaining a clean environment for those in her care, animal rescues must always contend with a formidable health challenge. Poor air quality impacts both kittens and the humans who care for them. Thanks to advanced air purification technology, the rescue now breathes easier—literally and figuratively. Mission built on compassion Mellissa’s journey to creating Tiny but Mighty began with heartbreak. As a volunteer at her local animal shelter, she learned of the euthanasia of kittens deemed too young to care for. Unwilling to accept this outcome, she founded her own kitten-focused rescue in 2017. “I had so many dreams about saving these kittens. Something told me to just do it myself—start my own rescue.” “I had so many dreams about saving these kittens.

Nova the kitten enjoying toys at the Tiny but Mighty Kitten Rescue. Good air quality: Essential in animal rescues Caring for kittens in any enclosed environment presents unique challenges. Despite her meticulous cleaning habits, Mellissa found air quality to be a problem. “The dust is crazy. The kittens will go in their litter box and sneeze.” There would still be dust, odors, and allergens in the space “even though I use 99% dust-free litter.” Mellissa explained. “It’s great compared to some I’ve tried, but the dust is crazy. The kittens will go in their litter box and make little sneezes.” This poor air quality not only affected visitors but also had potential health implications for the kittens and Mellissa herself. Dust mites, microscopic creatures that feed on animal’s dead skin, can cause year-round allergic reactions in both cats and humans, including sneezing, runny and itchy noses, watery eyes, and even rashes.
