Air pollution is a leading environmental risk to human health worldwide—but it is often invisible.

PM2.5, or fine particulate matter measuring 2.5 microns in diameter or smaller, is one of the clearest examples. Because these particles are so small, they can be inhaled deep into the lungs and enter the bloodstream. Research has linked PM2.5 exposure to asthma, cardiovascular disease, and other chronic health risks. A review of studies focused on children and adolescents noted that exposure to air pollution can lead to respiratory illness, neurodevelopmental impairment, and worsened chronic conditions (3). A study focused on older adults also found that exposure to PM2.5 and nitrogen dioxide may increase the risk of Alzheimer's disease and related dementias (4). How climate change and air pollution are connected Climate change and air pollution are also increasingly intertwined.

Where monitoring is sparse or absent, pollution becomes harder to track, health risks are harder to quantify, and communities have less evidence to support action. Some countries are routinely underrepresented in global air quality reporting not because pollution is absent, but because monitoring infrastructure is limited.

In some cities, expanding monitoring has helped connect pollution levels with public awareness and local action.

In Bogotá, Colombia, new “ZUMA” clean air zones prioritize the health of low-income communities by combining road paving, traffic restrictions, and urban greening.

Find out more about the Wellington flash floods impacting communities across New Zealand’s capital region.

","What is the location of the flooding? As of April 20, 2026, severe flash flooding is impacting Wellington, the capital of New Zealand, situated on the southern coast of the North Island. (1) The flooding has been driven by intense rainfall that has overwhelmed urban drainage systems and caused rivers and stormwater channels to overflow into surrounding neighborhoods. (2) The flooding is concentrated in low-lying urban areas, flood-prone suburbs, and regions near stormwater systems and coastal zones, with widespread impacts across the Wellington metropolitan area. Which cities or areas are affected by the flooding? The following cities and areas have been directly impacted by the flooding: Karori Kingston Lower Hutt Mornington Newtown Stokes Valley Wellington Whanganui District Floodwaters have impacted residential homes, roads, and infrastructure across these areas, with particularly severe impacts in southern and low-lying suburbs. (3) What is the current containment status of the flooding? As of April 20, 2026, the flooding is partially contained, with water levels receding in some areas while ongoing risks remain due to continued rainfall and saturated ground conditions. (4) Emergency crews are actively engaged in clean-up operations, debris removal, and response efforts. However, additional storms and heavy rain forecasts continue to pose a threat of further flooding. Are there any evacuation orders or alerts in place? Authorities have issued evacuation advisories for residents in low-lying and flood-prone areas, urging them to relocate to safer locations if conditions worsen and to avoid all non-essential travel. (5) Emergency shelters have been set up, including support services coordinated by the Wellington City Mission, to assist displaced residents. Officials have also warned the public not to walk or drive through floodwaters due to the risk of strong currents, hidden debris, and rapidly changing conditions. Emergency alerts remain in place as severe weather continues to pose risks, including further flooding and landslides. Emergency services have responded to a high number of incidents across the region, and residents are advised to stay informed through official updates and be prepared to act quickly if the situation escalates. How can I protect myself from mold after flooding? It’s important to take steps to prevent mold after a flood. Before entering a flooded area, make sure it is safe and free from electrical hazards or structural damage. Use protective gear: wear gloves, goggles, and a KN95/FFP2 mask to minimize exposure to mold spores. If there is still standing water, remove it as quickly as possible. Use pumps, wet-dry vacuums, or buckets to extract the water. Open windows and doors to facilitate air circulation and use fans, dehumidifiers, and HVAC systems to help dry the space. This step is crucial within the first 24-48 hours after flooding to prevent mold growth. Remove and discard any items that have been severely damaged by floodwater and cannot be thoroughly cleaned and dried. This includes carpets, upholstered furniture, mattresses, and any other porous materials. Thoroughly clean all hard surfaces with a detergent or cleaner suitable for mold remediation. Use a solution of 1.5 cups of bleach mixed with one gallon of water to disinfect nonporous surfaces. Never mix bleach with ammonia or other cleaning products, as the fumes are toxic. Maintain an indoor relative humidity (RH) of 35-50%. High humidity promotes mold growth, so consider using dehumidifiers in damp areas. Run a high-performance air purifier for mold, both during and after the mold removal work. If the flooding and mold damage are extensive, consider contacting professionals specializing in mold remediation to ensure proper cleanup and restoration. Remember, mold can pose health risks, so it's important to take these steps promptly and thoroughly. If you experience persistent mold-related health issues or have concerns about extensive mold growth, consult with a medical professional or a mold remediation specialist.","

Extensive flooding has caused most Michigan counties to enter a flood watch. Learn more about what is causing the Michigan floods.

","What is the location of the flooding? On April 15, 2026, intense rainfall on top of saturated snowy grounds has caused extensive flooding across northern and southwestern areas of Michigan. With an earlier onset of spring and warmer weather, previous snowfall melted at quick rates. On top of the rainy conditions, the excess water has caused small dam failures, an overflow of rivers and streams, as well as road closures (1). Counties across Michigan and neighboring states have received flood watch warnings including eastern Wisconsin, northern Indiana, northwestern Ohio, and northeastern Illinois (2). Which cities or areas are affected by the flooding? Most communities experiencing significant flooding are located near riverbanks or streams that have become overflown by flood water, including (3): River Oak, near Au Sable River Sherman, near Manistee River Evart, near Muskegon River Newaygo and Bridgeton, near Muskegon River Excess flooding usually collects and drains into larger bodies of water, creating massive overflow that has caused the damage and breakage of a few small, unregulated dams. What is the current containment status of the flooding? On April 15, 2026, the flood is ongoing as rainfall continues to feed into the overflow of water. Michigan has seen up to 2.5 inches of rainfall since Tuesday and is expected to receive an additional 3 inches over the next two days. County officials are preparing structures for impact, stacking sandbags along dams to reinforce the walls containing the excess water. Governor Gretchen Whitmer issued a statewide energy emergency, suspending some regulations to allow for faster response time (4). Are there any evacuation orders or alerts in place? County authorities across the state have issued individual warnings to various communities and begun evacuations for flood-prone areas. Almost the entire state has entered a flood watch warning or received evacuation notices. In Cheboygan, Michigan state troopers visited residents door-to-door to warn people and ensure everyone is aware of evacuation orders in place. Cheboygan County is located near Little Black River, which has caused a flooding for residents living in lower regions of the community (5). How can I protect myself from mold after flooding? It’s important to take steps to prevent mold after a flood. Before entering a flooded area, make sure it is safe and free from electrical hazards or structural damage. Use protective gear: wear gloves, goggles, and a KN95/FFP2 mask to minimize exposure to mold spores. If there is still standing water, remove it as quickly as possible. Use pumps, wet-dry vacuums, or buckets to extract the water. Open windows and doors to facilitate air circulation and use fans, dehumidifiers, and HVAC systems to help dry the space. This step is crucial within the first 24-48 hours after flooding to prevent mold growth. Remove and discard any items that have been severely damaged by floodwater and cannot be thoroughly cleaned and dried. This includes carpets, upholstered furniture, mattresses, and any other porous materials. Thoroughly clean all hard surfaces with a detergent or cleaner suitable for mold remediation. Use a solution of 1.5 cups of bleach mixed with one gallon of water to disinfect nonporous surfaces. Never mix bleach with ammonia or other cleaning products, as the fumes are toxic. Maintain an indoor relative humidity (RH) of 35-50%. High humidity promotes mold growth, so consider using dehumidifiers in damp areas. Run a high-performance air purifier for mold, both during and after the mold removal work. If the flooding and mold damage are extensive, consider contacting professionals specializing in mold remediation to ensure proper cleanup and restoration. Remember, mold can pose health risks, so it's important to take these steps promptly and thoroughly. If you experience persistent mold-related health issues or have concerns about extensive mold growth, consult with a medical professional or a mold remediation specialist.","

With an earlier onset of spring and warmer weather, previous snowfall melted at quick rates. On top of the rainy conditions, the excess water has caused small dam failures, an overflow of rivers and streams, as well as road closures (1).

Counties across Michigan and neighboring states have received flood watch warnings including eastern Wisconsin, northern Indiana, northwestern Ohio, and northeastern Illinois (2).

Which cities or areas are affected by the flooding?

Most communities experiencing significant flooding are located near riverbanks or streams that have become overflown by flood water, including (3):

River Oak, near Au Sable River
Sherman, near Manistee River
\nEvart, near Muskegon River
\nNewaygo and Bridgeton, near Muskegon River

Excess flooding usually collects and drains into larger bodies of water, creating massive overflow that has caused the damage and breakage of a few small, unregulated dams.

What is the current containment status of the flooding?

On April 15, 2026, the flood is ongoing as rainfall continues to feed into the overflow of water. Michigan has seen up to 2.5 inches of rainfall since Tuesday and is expected to receive an additional 3 inches over the next two days. County officials are preparing structures for impact, stacking sandbags along dams to reinforce the walls containing the excess water. Governor Gretchen Whitmer issued a statewide energy emergency, suspending some regulations to allow for faster response time (4).

Are there any evacuation orders or alerts in place?

County authorities across the state have issued individual warnings to various communities and begun evacuations for flood-prone areas. Almost the entire state has entered a flood watch warning or received evacuation notices. In Cheboygan, Michigan state troopers visited residents door-to-door to warn people and ensure everyone is aware of evacuation orders in place. Cheboygan County is located near Little Black River, which has caused a flooding for residents living in lower regions of the community (5).

How can I protect myself from mold after flooding?

It’s important to take steps to prevent mold after a flood.

Before entering a flooded area, make sure it is safe and free from electrical hazards or structural damage.
Use protective gear: wear gloves, goggles, and a KN95/FFP2 mask to minimize exposure to mold spores.
If there is still standing water, remove it as quickly as possible. Use pumps, wet-dry vacuums, or buckets to extract the water.
Open windows and doors to facilitate air circulation and use fans, dehumidifiers, and HVAC systems to help dry the space. This step is crucial within the first 24-48 hours after flooding to prevent mold growth.
Remove and discard any items that have been severely damaged by floodwater and cannot be thoroughly cleaned and dried. This includes carpets, upholstered furniture, mattresses, and any other porous materials.
Thoroughly clean all hard surfaces with a detergent or cleaner suitable for mold remediation. Use a solution of 1.5 cups of bleach mixed with one gallon of water to disinfect nonporous surfaces. Never mix bleach with ammonia or other cleaning products, as the fumes are toxic.
Maintain an indoor relative humidity (RH) of 35-50%. High humidity promotes mold growth, so consider using dehumidifiers in damp areas.
\nRun a high-performance air purifier for mold, both during and after the mold removal work.
If the flooding and mold damage are extensive, consider contacting professionals specializing in mold remediation to ensure proper cleanup and restoration.

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. That makes it especially relevant in situations where ultrafine pollution matters, such as wildfire smoke, traffic emissions, and other combustion-related indoor air concerns.

Airborne pollutants can cross continents and oceans, impacting lives far from their source; learn what we can do to control transboundary pollution.

","Air pollution is often discussed as a local problem. However, our climate system is singular and interconnects the entire planet. The atmosphere operates without political borders, as these are a human construct. Every year, desert dust, wildfire smoke, crop burning haze, and industrial emissions travel hundreds or even thousands of miles from where they began. A pollution event in one region can shape air quality, health risks, and public warnings far away. That makes air pollution more than a domestic policy issue. It is a shared public-health challenge—one that requires collective action—better monitoring, better coordination, and a clearer understanding that the air over one country rarely belongs to that country alone. Air pollution is one of the clearest examples of how environmental risks can move across political boundaries (1). The science, monitoring tools, and policy models to respond already exist—but acting on them requires coordination that matches how the atmosphere actually works. Why air pollution becomes everyone’s problem Wind patterns, seasonal weather systems, and jet streams can carry pollution across regions, continents, and oceans. That means the health effects of a pollution source are not always felt only where emissions begin. This matters because air pollution is already a major global health risk. The World Health Organization estimates that air pollution contributes to around 7 million premature deaths each year, many linked to respiratory and cardiovascular disease (2). The 2025 World Air Quality Report estimated that only 14% of global cities met recommended annual air quality guideline levels. When pollution crosses borders, it can complicate public-health warnings, blur accountability, and expose communities far from the original source. The costs are not only medical. Poor air quality can strain healthcare systems, disrupt schools and travel, reduce productivity, and create major economic losses (3). Yet despite this shared reality, air pollution is still too often treated as a domestic issue rather than a regional or global one. When desert dust travels thousands of miles One of the clearest examples of transboundary pollution is Saharan dust. Each year, powerful dust storms lift vast amounts of particles from North Africa and carry them westward across the Atlantic. In June 2020, a record-breaking Saharan dust plume—widely referred to as the “Godzilla Dust Storm”—traveled more than 5,000 miles, affecting air quality across the Caribbean, parts of the United States, Central America, and northern South America. During events like this, PM2.5 and PM10 concentrations can rise sharply, increasing health risks for people with asthma, cardiovascular disease, and other respiratory vulnerabilities. (4). While Saharan dust can play ecological roles—such as fertilizing parts of the Amazon—its health impacts are also well documented. Studies have found that Saharan dust events can worsen respiratory conditions and are associated with increased respiratory health risks (5). Vulnerable populations, including children, older adults, pregnant people, and those with pre-existing lung disease, may face greater risk during major dust episodes. Saharan dust affects health not only across North Africa, but also in parts of Europe and the Americas. Similar long-range dust transport also affects East Asia, where desert dust can degrade air quality in China, Korea, and Japan. How seasonal haze spreads across borders Though it’s a global practice, crop burning is particularly acute in South Asia and Southeast Asia. In South Asia, annual crop residue burning primarily in India and Pakistan creates a toxic smog that blankets Nepal, Bangladesh, and beyond (6). This seasonal haze spikes PM2.5 levels, leading to school closures, flight cancellations, and thousands of hospitalizations for respiratory distress. The 2013 “Airpocalypse” in China, meanwhile, saw PM2.5 concentrations reach extreme levels and reportedly drove Beijing Children’s Hospital to treat about 7,000 patients a day (7). The smog didn’t stop at China’s borders; it drifted into South Korea and Japan and prompted calls for greater regional cooperation (8). Airborne pollutants from Chinese factories and power plants can contribute to air quality problems in East Asia and beyond. While China has made progress in reducing domestic pollution—sulfur dioxide emissions have dropped by 75% between 2013 and 2020—the transboundary nature of the issue demands broader solutions (9). Wildfire smoke travels farther than most people think Wildfire smoke is another reminder that air pollution does not stop at the border. During Canada’s record-setting 2023 wildfire season, releasing an estimated 647 teragrams of carbon. The smoke spread across North America and, at times, across the Atlantic into Europe (10)(11). That smoke degraded air quality far from the fires themselves, exposing millions to elevated PM2.5 levels and producing hazy skies in cities thousands of miles away (12). Australia’s 2019–2020 bushfires offered another striking example. Smoke from those fires circled much of the globe and was detected as far away as South America and Antarctica (13). Greater regional planning and cooperation for wildfire season and its accompanying smoke is needed. As the climate warms, many regions are seeing longer and more intense wildfire seasons. In some places, fires are burning hotter, spreading farther, and producing more smoke over longer periods of time. Rather than blaming neighbors, greater regional planning and cooperation for wildfire season and its accompanying smoke is needed. Why national policy alone is not enough National air quality laws remain essential. They help countries regulate emissions, set standards, and build enforcement systems. But they are not enough on their own when pollution regularly travels beyond the jurisdiction that produced it. That is the central mismatch in transboundary air pollution: the atmosphere moves freely, while policy usually stops at the border. Domestic laws such as the U.S. Clean Air Act remain essential for source control and enforceable standards, but they cannot fully address pollution that regularly moves across jurisdictions (14). The ASEAN Agreement on Transboundary Haze Pollution, signed in 2002, remains one of the few regional agreements focused specifically on cross-border air pollution (15). While it has fostered some cooperation—such as shared monitoring and emergency response protocols—its effectiveness is limited by national sovereignty concerns and uneven enforcement. Cross-border monitoring systems, regional directives, and international clean air initiatives offer stronger models for cooperation—especially when they combine shared data, common standards, and earlier public-health warnings (16)(17)(18). Without that kind of coordination, health warnings can come later, accountability can weaken, and communities downwind are left to manage risks they did not create. Collective action needed across borders Transboundary air pollution is a large-scale problem, but not an abstract one. The most effective responses combine earlier warnings, stronger regional coordination, and practical steps that reduce exposure while cutting pollution at the source. What governments can do Expanded cross-border data sharing, real-time air quality monitoring, and unified standards can improve public health responses. Strengthen legally binding treaties and agreements with clear accountability mechanisms to reduce emissions at the source. By investing in renewable energy and sustainable agriculture, governments can cut pollution before it crosses borders. Enforce existing legislation and treaties to curtail industrial pollution and crop burning practices. What individuals can do Urge leaders to prioritize global air quality in climate and health agendas. Citizen-led air quality monitoring initiatives can help communities spot poor air days sooner and make better-informed choices, such as staying indoors or closing windows. Downloading a free air quality app can provide alerts when pollution levels rise On high-pollution days, running an air purifier and wearing a mask while outdoors can provide essential personal protection. Conclusion Air pollution may begin locally, but it often does not stay local. Dust, smoke, and industrial emissions can travel far beyond their source, exposing communities that had no role in creating them. That is why transboundary pollution requires more than national action alone. It requires shared data, earlier warnings, stronger regional coordination, and policies that reflect how the atmosphere actually works. The air people breathe is shaped not only by what happens nearby, but also by what happens upwind, across borders, and sometimes across oceans. Cleaner air depends on treating that reality as a shared responsibility.","

\nCitizen-led air quality monitoring initiatives can help communities spot poor air days sooner and make better-informed choices, such as staying indoors or closing windows.
\nDownloading a free air quality app can provide alerts when pollution levels rise
On high-pollution days, running an air purifier and wearing a mask while outdoors can provide essential personal protection.

Conclusion

Air pollution may begin locally, but it often does not stay local. Dust, smoke, and industrial emissions can travel far beyond their source, exposing communities that had no role in creating them.

That is why transboundary pollution requires more than national action alone. It requires shared data, earlier warnings, stronger regional coordination, and policies that reflect how the atmosphere actually works.

The air people breathe is shaped not only by what happens nearby, but also by what happens upwind, across borders, and sometimes across oceans. Cleaner air depends on treating that reality as a shared responsibility.

Find out more about Super Typhoon Sinlaku and its impact on the Mariana Islands.

","What is the name and location of the typhoon? As of April 13, 2026, Super Typhoon Sinlaku is an active and rapidly intensifying system in the western North Pacific Ocean, located southeast of Guam and moving toward the Northern Mariana Islands (1). Which cities or areas are affected by the typhoon? The typhoon is expected to significantly impact multiple areas across the Mariana Islands region, including: Northern Mariana Islands including Saipan, Tinian, and Rota Guam, a U.S. territory in the western Pacific (2) These regions are at risk of destructive winds, storm surge, flooding, and infrastructure damage as the typhoon approaches (3). What is the projected path and intensity of the typhoon? Super Typhoon Sinlaku is moving northwest and is expected to pass between Saipan and Tinian, tracking close to Guam, although a direct landfall is not certain (4). The typhoon has reached Category 5 strength and poses a serious threat. It has maximum sustained winds of up to 287 km/h or higher, with sustained wind speeds around 185 mph and gusts exceeding 220 mph. In addition to strong winds, the system may bring heavy rainfall exceeding 300 mm, along with dangerous storm surges. Sinlaku developed from thunderstorms in Micronesia and rapidly intensified due to warm ocean waters and low wind shear (5). Are there any evacuation orders or alerts in place? Authorities have issued multiple warnings and taken preparedness measures across affected regions to protect residents from the approaching typhoon. Typhoon warnings are in place for Saipan, Tinian, and Rota, where the most severe conditions are expected. Tropical storm warnings have been issued for Guam, where outer rainbands and strong winds are already beginning to impact the area. Officials have also declared a state of emergency in the Northern Mariana Islands to enable faster response and resource deployment. Emergency shelters have been opened in public buildings such as schools and community centers to accommodate residents, particularly those living in vulnerable or non-concrete housing. In total, seven shelters have been established as precautionary measures to ensure public safety. Residents are strongly advised to complete all necessary preparations, secure their homes, and follow instructions from local authorities, as life-threatening conditions including destructive winds, flooding, and storm surge are expected (6). How can I protect myself from mold after flooding? It’s important to take steps to prevent mold after a flood. Before entering a flooded area, make sure it is safe and free from electrical hazards or structural damage. Use protective gear: wear gloves, goggles, and a KN95/FFP2 mask to minimize exposure to mold spores. If there is still standing water, remove it as quickly as possible. Use pumps, wet-dry vacuums, or buckets to extract the water. Open windows and doors to facilitate air circulation and use fans, dehumidifiers, and HVAC systems to help dry the space. This step is crucial within the first 24-48 hours after flooding to prevent mold growth. Remove and discard any items that have been severely damaged by floodwater and cannot be thoroughly cleaned and dried. This includes carpets, upholstered furniture, mattresses, and any other porous materials. Thoroughly clean all hard surfaces with a detergent or cleaner suitable for mold remediation. Use a solution of 1.5 cups of bleach mixed with one gallon of water to disinfect nonporous surfaces. Never mix bleach with ammonia or other cleaning products, as the fumes are toxic. Maintain an indoor relative humidity (RH) of 35-50%. High humidity promotes mold growth, so consider using dehumidifiers in damp areas. Run a high-performance air purifier for mold, both during and after the mold removal work. If the flooding and mold damage are extensive, consider contacting professionals specializing in mold remediation to ensure proper cleanup and restoration. Remember, mold can pose health risks, so it's important to take these steps promptly and thoroughly. If you experience persistent mold-related health issues or have concerns about extensive mold growth, consult with a medical professional or a mold remediation specialist.","

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.

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.

Find out more about the ongoing Mayon Volcano eruption in Albay Province, including affected communities, evacuation measures, and volcanic activity updates.

","What is the name and location of the volcano? As of May 15, 2026, Mayon Volcano is actively erupting in Albay Province in the Bicol Region of southern Luzon, Philippines. Located approximately 330 kilometers southeast of Manila in the province of Albay, Mayon Volcano is part of the Pacific Ring of Fire, a region known for frequent volcanic eruptions and seismic activity. The volcano rises prominently near the municipalities of Camalig and Guinobatan, and the city of Ligao. It is internationally recognized for its remarkably symmetrical cone shape, making it one of the Philippines’ most iconic natural landmarks. Authorities continue to closely monitor volcanic activity and potential hazards within the six-kilometer Permanent Danger Zone surrounding the crater. (1) Which cities or areas are affected by the volcano? The following areas have been affected by ongoing volcanic activity from Mayon Volcano: Albay Province Basud Bonga Camalig Cagsawa Guinobatan Legazpi Ligao City Mi-isi Gully Misi At least 124 barangays across Albay Province have been affected by ashfall, lava flows, pyroclastic density currents, and volcanic activity. What is the current containment status of the volcano? As of May 15, 2026, Mayon Volcano remains under Alert Level 3 as volcanic unrest continues across the region. PHIVOLCS reported that the volcano has been undergoing an effusive eruption for 131 consecutive days, producing continuous lava flows, collapse-fed pyroclastic density currents, rockfalls, volcanic earthquakes, and minor strombolian activity at the summit crater. Lava flows have extended up to 3.8 kilometers along Basud Gully, 3.2 kilometers along Bonga Gully, and 1.6 kilometers along Mi-isi Gully (2). Monitoring data also recorded 71 volcanic earthquakes, 421 rockfall events, sulfur dioxide emissions averaging 889 tonnes per day, and ongoing ground deformation around the volcano. Authorities continue enforcing restrictions within the six-kilometer Permanent Danger Zone because hazardous eruptions, pyroclastic flows, and sudden explosive activity remain possible (3). Are there any evacuation orders or alerts in place? Authorities continue to enforce Alert Level 3 at Mayon Volcano and prohibit entry into the six-kilometer Permanent Danger Zone surrounding the crater.

What is the name and location of the volcano?

As of May 15, 2026, Mayon Volcano is actively erupting in Albay Province in the Bicol Region of southern Luzon, Philippines.

Located approximately 330 kilometers southeast of Manila in the province of Albay, Mayon Volcano is part of the Pacific Ring of Fire, a region known for frequent volcanic eruptions and seismic activity.

The volcano rises prominently near the municipalities of Camalig and Guinobatan, and the city of Ligao. It is internationally recognized for its remarkably symmetrical cone shape, making it one of the Philippines’ most iconic natural landmarks.

Authorities continue to closely monitor volcanic activity and potential hazards within the six-kilometer Permanent Danger Zone surrounding the crater. (1)

Which cities or areas are affected by the volcano?

The following areas have been affected by ongoing volcanic activity from Mayon Volcano:

Albay Province
Basud
Bonga
Camalig
Cagsawa
Guinobatan
Legazpi
Ligao City
Mi-isi Gully
Misi

At least 124 barangays across Albay Province have been affected by ashfall, lava flows, pyroclastic density currents, and volcanic activity.

What is the current containment status of the volcano?

As of May 15, 2026, Mayon Volcano remains under Alert Level 3 as volcanic unrest continues across the region.

PHIVOLCS reported that the volcano has been undergoing an effusive eruption for 131 consecutive days, producing continuous lava flows, collapse-fed pyroclastic density currents, rockfalls, volcanic earthquakes, and minor strombolian activity at the summit crater.

Lava flows have extended up to 3.8 kilometers along Basud Gully, 3.2 kilometers along Bonga Gully, and 1.6 kilometers along Mi-isi Gully (2).

Monitoring data also recorded 71 volcanic earthquakes, 421 rockfall events, sulfur dioxide emissions averaging 889 tonnes per day, and ongoing ground deformation around the volcano.

Authorities continue enforcing restrictions within the six-kilometer Permanent Danger Zone because hazardous eruptions, pyroclastic flows, and sudden explosive activity remain possible (3).

Are there any evacuation orders or alerts in place?

Authorities continue to enforce Alert Level 3 at Mayon Volcano and prohibit entry into the six-kilometer Permanent Danger Zone surrounding the crater.

PHIVOLCS has warned residents and visitors to remain outside restricted zones because lava flows, pyroclastic density currents, rockfalls, ashfall, and sudden explosive eruptions may occur without warning.

More than 287,000 people across the Philippines remain displaced or are sheltering due to the prolonged eruption.

Evacuation centers across Albay Province continue housing thousands of families as emergency response teams coordinate relief operations, distribute protective supplies, and monitor conditions in affected communities.

Authorities are also preparing for additional risks associated with the approaching rainy season, including lahars and flooding in communities surrounding the volcano.

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. Residents are advised to stay in air-conditioned spaces, avoid direct sun exposure, drink fluids, and check on elderly individuals. Outdoor workers should reschedule activities to cooler hours.","

","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.

Air quality map of Santiago, Chile, as of May 14, 2026, at 1:30 AM (local time). Source: IQAir. When will the air quality improve in Santiago? Every winter, Santiago's topography combined with an inverse temperature layer, little rain, and minimal airstream results in a low dispersion rate, insufficient to cope with progressively higher concentrations of pollutants emitted. May marks the beginning of this seasonal deterioration in the Southern Hemisphere. Pollution peaks during colder months, when firewood consumption increases and valley topography limits atmospheric dispersion. Short-term relief depends on favorable weather to break up the inversion layer. Lasting improvement over the coming months will require consistent enforcement of restrictions on wood burning and vehicle emissions during alert episodes (1). Hourly air quality forecast for Santiago, Chile, as of May 14, 2026, at 1:30 AM (local time). Source: IQAir. What is causing poor air quality in Santiago? Santiago is located in a basin bounded by the coastal ranges to its west, the Andean Cordillera to its east, and transversal ranges to its north and south, all of which function as natural barriers against the dispersion of air pollutants. This unfavorable geography is compounded by temperature inversions that restrict vertical mixing in the basin, especially during winter nights when inversion layers range between 200 and 400 m (2). Firewood burning for heating during colder months is a significant driver of PM2.5, and can account for up to 94% of fine particulate matter emissions in some Chilean cities according to the Chilean Ministry of Environment (3). Vehicle exhaust, fossil-fuel-powered energy generation, and construction dust compound the problem year-round, while weak winds and stagnant conditions during autumn and winter prevent pollutants from dispersing, causing rapid accumulation across the metropolitan area (4).

Poor air quality in São Paulo is being driven by a combination of wildfire smoke, biomass burning, and vehicle emissions. Research published in 2025 found that smoke from fires across Brazil and neighboring regions significantly increased PM2.5 pollution in São Paulo State during dry seasons, especially during periods of drought and extreme heat (1). Vehicle emissions are also a major contributor to pollution in the São Paulo Metropolitan Area. A 2025 emissions study found that older gasoline and diesel vehicles produced disproportionately high levels of nitrogen oxides and particulate pollution (2). Researchers have also warned that climate change may increase the frequency and severity of pollution episodes in São Paulo due to prolonged droughts and more intense fire seasons (3).

What is causing poor air quality in São Paulo?

Poor air quality in São Paulo is being driven by a combination of wildfire smoke, biomass burning, and vehicle emissions.

Research published in 2025 found that smoke from fires across Brazil and neighboring regions significantly increased PM2.5 pollution in São Paulo State during dry seasons, especially during periods of drought and extreme heat (1).

Vehicle emissions are also a major contributor to pollution in the São Paulo Metropolitan Area. A 2025 emissions study found that older gasoline and diesel vehicles produced disproportionately high levels of nitrogen oxides and particulate pollution (2).

Researchers have also warned that climate change may increase the frequency and severity of pollution episodes in São Paulo due to prolonged droughts and more intense fire seasons (3).

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.

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?

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.

$\"Air$

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:

\nHyperHEPA media for particle filtration
\nNo system leakage due to sealed filter and purifier housing
\nActivated 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):

\nIonizer 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.
\nIonizer 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. \n

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):

\nOzone can take years to fully clear even a small room of gases.
\nOzone 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.
\nIndoor 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):

\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.

Studies show that these particles can penetrate deep into your respiratory system and cause both heart and lung conditions.2The 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.

Tropospheric 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. Negative ionization can generate tropospheric ozone indoors. While stratospheric ozone has no interaction with us in the lower atmosphere, ground-level ozone is far more harmful when it builds up to high levels.

First used in Eastern Europe, speleotherapy consists of spending time in a salt cave, where four environmental conditions are thought to help reduce symptoms of respiratory illness:5 Stable air temperature Moderate to high humidity Presence of aerosol elements, such as sodium, potassium, and magnesium 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. But there’s no conclusive evidence that either speleotherapy or halotherapy actually relieve respiratory symptoms.6Take the claims with a grain of...well, saltSo here’s the takeaway: We’re not saying you shouldn’t get a Himalayan salt lamp. Their dim glow can be quite soothing at night when you’re trying to fall asleep.But they don’t purify air. And “air purifiers” that emits ions and ozone may make your indoor air quality worse, introduce new health problems, and exacerbate existing ones.You can take many precautions to monitorand keep your indoor air clean, but buying a salt lamp isn’t one of them.

The AirVisual Series consists of portable air quality monitors that use cutting-edge laser technology to give you real-time measurements of key pollutants, including particulate matter. AirVisual Series also provides 72-hour historical and forecast data so that you can know exactly when and why your indoor air quality changes. Control sources of poor indoor air quality. If you’re thinking about buying a salt lamp to purify your air, chances are that you do have air quality issues that you may be able to do something about. The first step to improving your indoor indoor air quality is source control.This means eliminating individual sources of pollution or reducing their emissions. Regularly clean your HVAC system ducts. Install a whole-house air purifier into your HVAC system to reduce indoor pollutants by up to 95%. Replace water-damaged areas of your home to prevent mold and dust mites. Keep paints, solvents, and other chemicals in well-ventilated areas. Ventilate your home. Let in fresh air regularly to lower the concentrations of indoor air pollutants. This is especially important if you live in an airtight, energy-efficient home in which indoor pollutants have nowhere to go and thus build up to dangerous levels. Open doors and windows when outdoor air quality is good. Use a range hood for your stove to capture gases and volatile organic compounds (VOCs) from cooking. Use an air purifier with HyperHEPA technology.

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.

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.

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. But there’s no conclusive evidence that either speleotherapy or halotherapy actually relieve respiratory symptoms.⁶

Take the claims with a grain of...well, salt

So here’s the takeaway: We’re not saying you shouldn’t get a Himalayan salt lamp. Their dim glow can be quite soothing at night when you’re trying to fall asleep.

But they don’t purify air. And “air purifiers” that emits ions and ozone may make your indoor air quality worse, introduce new health problems, and exacerbate existing ones.

You can take many precautions to monitorand keep your indoor air clean, but buying a salt lamp isn’t one of them. Try these proven methods instead:

\nBe aware of your indoor air quality. The AirVisual Series consists of portable air quality monitors that use cutting-edge laser technology to give you real-time measurements of key pollutants, including particulate matter. AirVisual Series also provides 72-hour historical and forecast data so that you can know exactly when and why your indoor air quality changes.
\nControl sources of poor indoor air quality. If you’re thinking about buying a salt lamp to purify your air, chances are that you do have air quality issues that you may be able to do something about. The first step to improving your indoor indoor air quality is source control.This means eliminating individual sources of pollution or reducing their emissions.\n\n\t
- Regularly clean your HVAC system ducts. Install a whole-house air purifier into your HVAC system to reduce indoor pollutants by up to 95%.
- Replace water-damaged areas of your home to prevent mold and dust mites.
- Keep paints, solvents, and other chemicals in well-ventilated areas.
\n\n\t
\nVentilate your home. Let in fresh air regularly to lower the concentrations of indoor air pollutants. This is especially important if you live in an airtight, energy-efficient home in which indoor pollutants have nowhere to go and thus build up to dangerous levels.\n\n\t
- Open doors and windows when outdoor air quality is good.
- Use a range hood for your stove to capture gases and volatile organic compounds (VOCs) from cooking.
\n\n\t
\nUse an air purifier with HyperHEPA technology. The IQAir HealthPro Plusis the best air purifier for even the smallest pollutant particles, removing up to 99.5% of particulates down to 0.003 microns, like viruses and ultrafine particles from vehicle exhaust. The Atempersonal air purifier can also provide pure, pollutant-free air directly into your personal breathing zone.

Sure, a salt lamp can be a nice accessory and bring some calm into your home. But there’s plenty you can do to actually keep your indoor air clean and bring yourself some peace of mind knowing that your home is a clean air sanctuary.

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.

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.

","“Every day, I witness the severe impact of poor air quality on my community,” Tedy Mwendwa explained. “Using my expertise in electrical engineering, I felt compelled to create change.” In the heart of Africa, amidst bustling cities and vibrant rural landscapes, Mwendwa is pioneering a movement for cleaner air in Kenya. 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. The TOF-ACSM will help identify pollution sources—from mineral dust kicked up by unpaved roads and construction to organic aerosols tied to biomass burning and traffic emissions. It will also track seasonal and daily shifts in air quality, influenced by weather patterns and human activity. The initiative is expanding further with the deployment of GRIMM EDM 180 reference monitors across Nairobi, replacing older equipment to deliver faster, more accurate readings with minimal maintenance. In collaboration with the Kenya National Highways Authority (KENHA), these monitors will be placed along major highways and construction zones, ensuring data reflects the realities of urban life.

WWF Pakistan is tackling air pollution with IQAir. Learn how real-time data is driving change across the country.

","In Pakistan, where vast horizons stretch beneath seemingly clear skies, severe air pollution silently impacts public health and well-being nationwide. Yet, due to a dire lack of data and awareness, the scale of the threat remains largely unseen. Recognizing the urgency of this crisis, WWF-Pakistan has taken significant steps to address air pollution using IQAir’s air quality monitoring technology. WWF-Pakistan has successfully deployed 15 stations across Pakistan and published data to IQAir’s AirVisual platform, establishing the country’s largest air quality monitoring network. With this initiative, WWF-Pakistan is transforming how the country understands and confronts this invisible threat. \"We have successfully reached the goal of installing AirVisual Outdoor sensors in 15 of our offices across Pakistan,\" said WWF-Pakistan’s Research Officer, Muhammad Huzaifa who led this initiative in Pakistan. As of now, WWF-Pakistan has air monitoring stations located in key regions like Karachi, Lahore, Quetta, Multan, and Peshawar. They provide real-time data that is accessible to both policymakers and the public. \"We are excited to say that we’ve published the data from these stations to IQAir’s platform, where communities can see their local air quality in real-time.” Pakistan's Air Quality Challenge Pakistan's urban centers, such as Lahore, Peshawar and Karachi, frequently grapple with thick layers of smog. While this is a visible reminder of air pollution, the more dangerous pollutants often remain unseen and unmonitored. One of the greatest challenges in Pakistan has been the need for more reliable, public air quality data. \"Our air quality network provides crucial air quality data in some of Pakistan’s most polluted regions, and are often ranked among the top 10 most polluted cities in the world\" Huzaifa explained. WWF-Pakistan, the nation’s largest environmental organization, has been addressing critical environmental issues since 1970. Originally focused on protecting wildlife and ecosystems, the organization’s scope has broadened to include tackling climate change, protecting vulnerable habitats, and securing vital resources like freshwater. Now, through their air quality monitoring initiative, they are addressing one of the most pressing health and environmental crises facing Pakistan. “Unfortunately, there is little public air quality data available,” Huzaifa noted. “This information vacuum has left policymakers and citizens unprepared to tackle the pollution crisis.” WWF-Pakistan’s initiative helps fill this gap, ensuring the public has access to real-time, localized air quality data. With real-time data now available, citizens, governments, and policymakers can work together to implement solutions, reduce pollution and improve health outcomes across the country. Rolling Out Pakistan’s Air Quality Network WWF-Pakistan’s initiative, which involves installing a total of air quality sensors in 15 key cities across the country, marks a critical step in Pakistan’s battle against air pollution. All 15 stations are currently up and running. Partnering with IQAir adds both credibility and precision to the project. \"IQAir's AirVisual air quality monitors are globally recognized for their accuracy and ability to track even the smallest fluctuations in air quality,\" said Huzaifa. \"IQAir's technology is built to withstand all sorts of weather and having it in place ensures that people will trust the data.\" This transparency is essential for mobilizing both community efforts and policy interventions, as reliable information is crucial to driving meaningful change. Air Quality Data in Action With the sensors online and data flowing into the IQAir platform, WWF-Pakistan's live contributor profile showcases the impact of their work, allowing anyone to monitor air quality in real-time.

In Pakistan, where vast horizons stretch beneath seemingly clear skies, severe air pollution silently impacts public health and well-being nationwide. Yet, due to a dire lack of data and awareness, the scale of the threat remains largely unseen.

Recognizing the urgency of this crisis, WWF-Pakistan has taken significant steps to address air pollution using IQAir’s air quality monitoring technology. WWF-Pakistan has successfully deployed 15 stations across Pakistan and published data to IQAir’s AirVisual platform, establishing the country’s largest air quality monitoring network. With this initiative, WWF-Pakistan is transforming how the country understands and confronts this invisible threat.

\"We have successfully reached the goal of installing AirVisual Outdoor sensors in 15 of our offices across Pakistan,\" said WWF-Pakistan’s Research Officer, Muhammad Huzaifa who led this initiative in Pakistan.

As of now, WWF-Pakistan has air monitoring stations located in key regions like Karachi, Lahore, Quetta, Multan, and Peshawar. They provide real-time data that is accessible to both policymakers and the public. \"We are excited to say that we’ve published the data from these stations to IQAir’s platform, where communities can see their local air quality in real-time.”

Pakistan's Air Quality Challenge

Pakistan's urban centers, such as Lahore, Peshawar and Karachi, frequently grapple with thick layers of smog. While this is a visible reminder of air pollution, the more dangerous pollutants often remain unseen and unmonitored. One of the greatest challenges in Pakistan has been the need for more reliable, public air quality data.

\"Our air quality network provides crucial air quality data in some of Pakistan’s most polluted regions, and are often ranked among the top 10 most polluted cities in the world\" Huzaifa explained.

WWF-Pakistan, the nation’s largest environmental organization, has been addressing critical environmental issues since 1970. Originally focused on protecting wildlife and ecosystems, the organization’s scope has broadened to include tackling climate change, protecting vulnerable habitats, and securing vital resources like freshwater. Now, through their air quality monitoring initiative, they are addressing one of the most pressing health and environmental crises facing Pakistan.

“Unfortunately, there is little public air quality data available,” Huzaifa noted. “This information vacuum has left policymakers and citizens unprepared to tackle the pollution crisis.” WWF-Pakistan’s initiative helps fill this gap, ensuring the public has access to real-time, localized air quality data.

With real-time data now available, citizens, governments, and policymakers can work together to implement solutions, reduce pollution and improve health outcomes across the country.

Rolling Out Pakistan’s Air Quality Network

WWF-Pakistan’s initiative, which involves installing a total of air quality sensors in 15 key cities across the country, marks a critical step in Pakistan’s battle against air pollution. All 15 stations are currently up and running.

Partnering with IQAir adds both credibility and precision to the project. \"IQAir's AirVisual air quality monitors are globally recognized for their accuracy and ability to track even the smallest fluctuations in air quality,\" said Huzaifa. \"IQAir's technology is built to withstand all sorts of weather and having it in place ensures that people will trust the data.\" This transparency is essential for mobilizing both community efforts and policy interventions, as reliable information is crucial to driving meaningful change.

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. This national conversation is already making a policy impact. The Ministry of Health has issued public health advisories several times since the air quality sensors were deployed, raising air quality awareness in communities around the country. Dr. Touray emphasizes the importance of partnering with the Gambian government to leverage their data for national air quality standards and planning. \"Working closely with governmental bodies is crucial for our success,\" Dr. Touray notes, highlighting his strong connections within the National Environment Agency, which have been supportive of their endeavors.

A kitten rescue in Ontario needed a powerful clean air solution fast – and found it. Learn more about the essential role of clean air in shelters.

","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. They wouldn’t let up,” Mellissa shared. “Something told me to just do it myself—start my own rescue.” Mellissa provides a safe space for kittens to grow and thrive until they find their carefully screened forever homes. Today, the rescue operates solely on donations and community support. “It’s such an incredible community. People do come through to support what I’m doing, so it’s incredible.” But running a rescue isn’t without its challenges, and one significant one she uncovered was air quality. 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. Components of pet dander can also act as an allergen, triggering similar reactions. Determined to find a solution to her dust problem, she began her search for an air purifier that could meet the rescue’s unique needs. Life changing air cleaning solution Determined to tackle the persistent dust and allergens, Mellissa sought an air purifier that could truly meet the unique demands of her rescue. After years of frustration with a previous model, she knew she needed a solution that could handle constant activity, fine dust particles, and odors effectively. Mellissa recalled, “The dust was still spreading throughout the house, and I thought, ‘this is just not enough.’” That’s when Mellissa’s father suggested looking into IQAir’s HealthPro Plus XE. Intrigued by its reputation for advanced filtration capabilities, Mellissa decided to give it a try—and the results were immediate and noticeable. The HealthPro Plus XE is equipped with HyperHEPA filtration, capable of capturing particles as small as 0.003 microns—100 times smaller than most air purifiers can filter. This efficiency, proven to remove particles far smaller than bacteria or viruses, combined with gas-phase filtration to eliminate odors, made it an ideal solution for the rescue’s air quality challenges. “The kittens aren’t sneezing anymore. The air purifier has had a huge impact,” Mellissa shared. The HealthPro Plus XE at work next to Leia the cat. Not only did she see a dramatic improvement in the air quality for the kittens, but visitors also noticed the difference. The previously lingering food and litter odors were gone. “I definitely don’t smell that anymore,” Mellissa said. “I’m really impressed.” “The kittens aren’t sneezing anymore. The air purifier has had a huge impact.” When it comes to daily use, Mellissa has found a setup that works perfectly for the rescue’s needs. During cleaning, she runs the fan at its highest setting, ensuring dust and particles are quickly filtered out. For everyday operation, she adjusts the fan to levels 2 or 3, which run quietly enough not to disturb the kittens at night. Looking ahead For Mellissa, clean air ensures a brighter future for Tiny but Mighty Kitten Rescue. She intends to continue providing even more kittens with a safe haven before transitioning to loving homes. The cleaner air and lack of odor in the rescue has already improved adoption visits, a critical step in finding forever homes for the kittens. Mellissa emphasizes her desire to address the root cause of ownerless kittens—unspayed and neutered animals in the population. She hopes to get the word out to more pet owners about the crucial role of spaying and neutering their animals. As she warns, “the cat overpopulation is so crazy here. Spay and neuter your cats, spay and neuter your dogs to help lower those populations.” Conclusion Tiny but Mighty Kitten Rescue’s story underscores the profound difference clean air technology can make in transforming lives—both human and animal. For Mellissa, investing in air purification wasn’t just about solving a nuisance; it was about creating a healthier, more inviting space where kittens could thrive and visitors could feel comfortable. By addressing the often-overlooked issue of air quality, she has set a powerful example for other rescues, shelters, and even individual pet owners facing similar challenges.","

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. They wouldn’t let up,” Mellissa shared. “Something told me to just do it myself—start my own rescue.”

Mellissa provides a safe space for kittens to grow and thrive until they find their carefully screened forever homes. Today, the rescue operates solely on donations and community support. “It’s such an incredible community. People do come through to support what I’m doing, so it’s incredible.”

But running a rescue isn’t without its challenges, and one significant one she uncovered was air quality.

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.

Components of pet dander can also act as an allergen, triggering similar reactions.

Determined to find a solution to her dust problem, she began her search for an air purifier that could meet the rescue’s unique needs.

Life changing air cleaning solution

Determined to tackle the persistent dust and allergens, Mellissa sought an air purifier that could truly meet the unique demands of her rescue. After years of frustration with a previous model, she knew she needed a solution that could handle constant activity, fine dust particles, and odors effectively.

Mellissa recalled, “The dust was still spreading throughout the house, and I thought, ‘this is just not enough.’”

That’s when Mellissa’s father suggested looking into IQAir’s HealthPro Plus XE. Intrigued by its reputation for advanced filtration capabilities, Mellissa decided to give it a try—and the results were immediate and noticeable.

The HealthPro Plus XE is equipped with HyperHEPA filtration, capable of capturing particles as small as 0.003 microns—100 times smaller than most air purifiers can filter. This efficiency, proven to remove particles far smaller than bacteria or viruses, combined with gas-phase filtration to eliminate odors, made it an ideal solution for the rescue’s air quality challenges.

“The kittens aren’t sneezing anymore. The air purifier has had a huge impact,” Mellissa shared.

Not only did she see a dramatic improvement in the air quality for the kittens, but visitors also noticed the difference. The previously lingering food and litter odors were gone. “I definitely don’t smell that anymore,” Mellissa said. “I’m really impressed.”

“The kittens aren’t sneezing anymore. The air purifier has had a huge impact.”

When it comes to daily use, Mellissa has found a setup that works perfectly for the rescue’s needs. During cleaning, she runs the fan at its highest setting, ensuring dust and particles are quickly filtered out. For everyday operation, she adjusts the fan to levels 2 or 3, which run quietly enough not to disturb the kittens at night.

Looking ahead

For Mellissa, clean air ensures a brighter future for Tiny but Mighty Kitten Rescue. She intends to continue providing even more kittens with a safe haven before transitioning to loving homes.

The cleaner air and lack of odor in the rescue has already improved adoption visits, a critical step in finding forever homes for the kittens.

Mellissa emphasizes her desire to address the root cause of ownerless kittens—unspayed and neutered animals in the population. She hopes to get the word out to more pet owners about the crucial role of spaying and neutering their animals. As she warns, “the cat overpopulation is so crazy here. Spay and neuter your cats, spay and neuter your dogs to help lower those populations.”

Conclusion

Tiny but Mighty Kitten Rescue’s story underscores the profound difference clean air technology can make in transforming lives—both human and animal.

For Mellissa, investing in air purification wasn’t just about solving a nuisance; it was about creating a healthier, more inviting space where kittens could thrive and visitors could feel comfortable. By addressing the often-overlooked issue of air quality, she has set a powerful example for other rescues, shelters, and even individual pet owners facing similar challenges.
