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

","content","In the slender West African nation of Gambia, Dr. Sunkaru Touray of Permian Health Lung Institute is leading an unprecedented initiative to illuminate the invisible dangers of air pollution through the strategic deployment of low-cost air quality monitors. A vision born from necessity Dr. Touray, a pulmonologist and critical care physician originally from Kartong, The Gambia, was profoundly affected by the respiratory issues he encountered while practicing in New Mexico. These issues, often linked to hydrocarbon exposure and environmental pollutants, spurred him to address similar problems in Gambia, where air quality data is scarce. \"There's a significant data gap in Africa when it comes to understanding our air,\" Dr. Touray noted. Recognizing the parallels between New Mexico and Gambia, Dr. Touray envisioned the Permian Health Clean Air Initiative. This initiative aims not only to collect data but to empower Gambians with knowledge, enabling them to make informed decisions about their health and advocate for cleaner air. “There’s a significant data gap in Africa when it comes to understanding our air.”–Dr. Sunkaru Touray, Founder, Permian Health The journey of Permian Health Permian Health's mission is clear: to democratize access to air quality data in Gambia by installing low-cost air quality monitors throughout the country. The team selected IQAir’s AirVisual outdoor monitors for this critical work. “These devices are proven to be reliable, user-friendly, and can operate on solar power,” Dr. Touray said. “They also have 4G LTE connectivity,” which make the monitors ideally suited for Gambia's diverse environments—from the bustling streets of Banjul to the rural countryside. \"The goal,\" Dr. Touray explained, \"is not just to collect data but to empower our communities with knowledge so they can make informed decisions about their health and advocate for cleaner air.\" Highlighting areas of concern: Brikama’s air quality Brikama stands as a poignant example of the challenges faced across Gambia. Known for its bustling markets and as a hub for both commerce and community life, the town also grapples with air quality issues that pose risks to its residents. By placing monitors in strategic locations, including the busy highway through Brikama, Permian Health is mapping pollution levels and raising awareness among the local population about the air they breathe daily—while simultaneously acting as a testament to the potential of grassroots air monitoring networks in challenging regions. Dr Touray said, \"As we look to the future, the lessons learned from Brikama will inform our expansion strategies to other regions facing similar challenges. Our success in achieving nationwide coverage, with Brikama as a keystone in our network, exemplifies the scalable model of Permian Health Clean Air Initiative.” “The goal is not to just collect the data but to empower our communities with knowledge so they can make informed decisions about their health.” Local feedback has been largely positive. According to Dr. Touray, real-time access to air quality monitor information has improved local understanding of the dangers of poor air quality, especially during the dry, dusty Harmattan season typically experienced from November to March. Permian Health has collaborated with local groups such as the Brikama Nema Diaspora Group (BRIND) and Karamie’s Health clinic to install sensors in key areas, allowing residents and medical professionals to access real-time air quality data. Pioneering work on the ground To date, the Permian Health air quality network has grown to 14 sensors, achieving nationwide coverage with an air quality sensor in all regions of The Gambia—proof of the project's rapid scalability and success. The project has successfully installed air quality monitors in various locations, including urban areas and industrial sites. These monitors provide real-time data on pollutants like PM2.5, which pose the greatest threat to human health, offering invaluable insights into the air pollution across different regions of Gambia. \"We have sensors in the most densely populated areas,” Dr. Touray said. \"Through the process of collecting PM 2.5 data in Gambia and identifying pollution hotspots, we educate the public about air quality and its impact on public health—and also communicate the importance of installing air quality sensors as a means to make a change.\" This foundational work sets the stage for enhanced accuracy and credibility in air quality monitoring, as underscored by a pivotal development in the project's journey. “The recent addition of a reference-grade monitor donated by MetOne marks a significant leap in our capacity for precision and validation of the data collected by our existing sensor network,” Dr. Touray said. However, maintaining and expanding the network can be impeded by dust accumulation on solar panels during the Harmattan season, unreliable power supplies, and other issues. ‘While we have made significant progress in addressing some of these challenges, connectivity and maintenance in remote areas remain ongoing hurdles in our efforts to maintain and expand the sensor network efficiently,’ Dr. Touray explained. Uniting minds and garnering accolades To raise awareness about their work, Permian Health has created a promotional video which serves as a powerful tool to inform and engage the public about their project. A key milestone for the project was the establishment of the first air quality conference in Gambia, bringing together stakeholders from the government, academia, and civil society to discuss the findings and implications of the collected data. \"This conference was a pivotal moment for us, marking the beginning of a national conversation on air quality,\" reflects Dr. Touray. 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. With the NEA, Permian Health was able to release their first air quality report based on initial installations. This sets the table for future updates from newly installed sensors. Additionally, the project's recent recognition by the Energy Policy Institute of the University of Chicago with an Air Quality Award highlights the global acknowledgment of their impactful work. This prestigious award will enable Permian Health to scale their network further. Currently, there are 22 low-cost sensors deployed, and Gambia will, for the first time ever, have a reference monitor to assist in enhancing air quality monitoring and assessment. Hopes for the Future Thanks to their recent Air Quality Award, Permian Health acquired an 10 sensors, bringing the total to 26 sensors across The Gambia. Six new sensors have been deployed to NEA headquarters, two major health centers with support from the Ministry of Health, and in housing developments in partnership with Gambia’s largest real estate company, TAF Africa Global. The remaining sensors will be deployed to the National Stadium, Gambia International Airport, the Seaport in Banjul, and a major intersection as soon as final government approvals are processed. Dr. Touray envisions a future where every Gambian has access to air quality information, enabling them to protect themselves and their families from air pollution. Furthermore, he hopes to leverage the data collected to advocate for stronger environmental policies and regulations in Gambia. “We’re not just collecting data for the sake of it. We want to drive change.” \"We're not just collecting data for the sake of it. We want to drive change,\" says Dr. Touray. \"Our ultimate goal is for Gambia to set national air quality standards, informed by the comprehensive data we've gathered.\" A key step toward this goal is the second Clean Air Conference, which Permian Health is organizing in partnership with the NEA. The event will bring together stakeholders, including officials from the ministries of Health, Environment, Transport, and Education, to develop a national air quality work plan. According to Dr. Touray, Permian Health is conducting an inventory assessment to determine the key sources of pollution, such as waste burning, reliance on charcoal and firewood for cooking, and transport-related emissions. \"Looking ahead, we aim to strengthen our collaboration with the NEA and the Ministry of Health, to expand and maintain our sensor network.\" \"We plan to enhance public awareness campaigns, especially during high-risk periods, to better inform the community about air quality concerns. We would also like to engage more with local TV stations for them to display air quality and weather information from our network. The takeaway Dr. Sunkaru Touray's work with Permian Health exemplifies innovative activism. The project not only addresses air quality data gaps but also empowers communities to tackle air pollution—an issue that transcends borders. Dr. Touray's mission goes beyond monitoring; it's about transforming the fabric of public health through the lens of air quality.","contentHtml","

Discover how Tedy Mwendwa's air quality monitoring project in Nairobi is bridging critical gaps in Africa's air quality data. Learn more.

","“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. These advancements are part of the NBO-CHEM Project (Nairobi Aerosol Chemistry and Monitoring Initiative), an effort funded by the U.S. National Science Foundation (NSF) and led by Prof. Daniel M. Westervelt, Dr. Godwin Opinde, and Tedy Mwendwa. By combining local expertise with state-of-the-art scientific resources, the project aims to transform how we understand air pollution in East Africa. The challenge of air quality monitoring in Africa The new additions to the project are heartening developments towards advancing air quality understanding in East Africa. Yet, despite the increasing efforts to monitor air quality globally, Africa remains one of the most underrepresented continents in terms of air quality data. According to the 2024 World Air Quality Report, there is only one monitoring station for every 3.7 million people. While coverage has expanded to include more African countries in recent years, there are still vast areas without sufficient data. For example, countries like Niger and Sudan remain without publicly available monitoring data.Air pollution is a major health threat, causing an estimated seven million premature deaths worldwide each year. Without accurate data, it is challenging to address the sources and impacts of air pollution effectively. Grassroots efforts like Mwendwa's are crucial in filling these data gaps, providing models for further projects and inspiring broader initiatives. Harnessing technology for a healthier tomorrow Utilizing an AirVisual Outdoor air quality monitor, Mwendwa’s station gathers critical real-time data. “The AirVisual sensor was easy to deploy and requires little maintenance, even in our somewhat extreme conditions with limited resources,” he said.The project, though small, is already making a difference in the community. “By sharing a link to the AirVisual Platform and using the app, we can easily get our data to students nationwide, enabling them to conduct their own research on pollution,” he said. The data has also been used to inform parents with small children of the effects of poor air quality. \"They need to understand that this data can help give them a better life,\" Mwendwa said.

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

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.

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.

Himalayan salt lamps DO NOT purify indoor air.

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

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

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

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

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

Why are Himalayan salt lamps bad for air quality?

Again, two words: negative ionization.

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

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

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

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

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

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

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

There are two main types of ozone:

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

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. And perhaps one of the starkest examples of ground-level ozone is one that millions of us know very well – the smog that forms in major cities during rush hour.

If you live near a freeway, dense urban center, or even at a high elevation where you can see the area around an urban area. A few hours or less after rush hour begins and the sun begins to rise, you’ll start to notice a visible layer of haze build up. This is ground-level ozone, and even though it’s a typical feature of modern life, extensive research shows that it causes a plethora of immediate symptoms, including:

Coughing
Wheezing
Trouble breathing
Stuffy nose
Dizziness
Tingling in arms and legs
Fever^3,4\n

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

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

So what’s so special about Himalayan salt?

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

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

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

Stable air temperature
Moderate to high humidity
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.⁶

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

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.

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.

","Where are the Indonesian wildfires burning? As of October 1, 2026, Indonesia is experiencing ongoing widespread forest and land fires, known nationally as karhutla. The event consists of surface and underground fires burning across the archipelago, with the heaviest activity concentrated in Kalimantan and Sumatra. Another major front is in South Papua. Many of the fires are burning in Kalimantan, the Indonesian portion of Borneo. West Kalimantan has recorded the largest cumulative burned area of any province, followed by Central Kalimantan and South Papua. There are additional fires burning in South Kalimantan and East Kalimantan. What distinguishes this event from a conventional forest fire is the fuel. Indonesia holds roughly 36 percent of the world's tropical peatlands, and when those waterlogged soils are dried by drought, fire moves below the surface and smolders through deep organic deposits, producing about three times more fine particulate matter, five times more sulfur dioxide, three times more organic carbon, and twice the methane and carbon monoxide of other tropical forest fires (1). Fire has also reached protection forests, conservation forests, and Key Biodiversity Areas, along with national parks and forest reserves stretching from the Gunung Kendeng forest area in Central Sulawesi to protected peat domes in Kalimantan. Research on past seasons has established that these fires are overwhelmingly human-ignited, with El Niño conditions and rural land-clearing practices together explaining most of the year-to-year variation in burning (2). Which cities or areas are affected by the wildfires? The cities and areas affected by the Indonesia wildfires include: Banjarmasin and surrounding areas in South Kalimantan Central Kalimantan East Kalimantan Jambi Ketapang Regency, West Kalimantan Merauke Regency, South Papua Riau South Sumatra West Kalimantan Smoke exposure extends well beyond the burn areas themselves. More than 12.5 million people across seven Indonesian provinces have been exposed to haze, and respiratory infections linked to the fires rose to 113,336 cases as of September 9, roughly double the 50,891 cases recorded on September 1 (3). Throughout September, Kuching, Kuala Lumpur, and Singapore have frequently ranked among the most polluted major cities in the world as wildfire haze affected the region. Air quality map of Southeast Asia, on October 1, 2026. Source: IQAir. What is the current containment status of the wildfires? As of October 1, 2026, firefighting progress varies across Indonesia. Some fires have been extinguished or entered the cooling stage, while active fires and peat hotspots remain in several regions. Indonesia's National Disaster Mitigation Agency (BNPB) reported that around 3,800 hectares of forest and land fires had been extinguished between September 24 and 30, 2026 (6). Weather remains the limiting factor. Indonesia's meteorological agency has confirmed that September is still a critical phase, with dry conditions dominant, rain cloud potential low across most of the country, and El Niño expected to persist into early 2027, meaning natural rainfall is unlikely to help extinguish the fires in the near term (7). Between September 1 and September 7, Indonesia released 19.7 million metric tons of fire emissions, the highest of any country in the world that week and more than a third of the global total (8). Why are Indonesia's 2026 wildfires so severe? Indonesian authorities describe this as the most intense wildfire season in 11 years. A strong El Niño, reinforced by a positive Indian Ocean Dipole, left about 90 percent of the country with little to no rain in early August, drying peat deposits that are normally too wet to burn underground. Forecasters expect El Niño to persist into early 2027, with low rain cloud potential across most of the archipelago, so the rainfall that usually ends the season may not arrive until late October or November (9). Peat smolders below the surface at low temperatures rather than burning through the canopy, which makes these fires both difficult to extinguish and exceptionally polluting. Drought creates the conditions, but ignition is almost entirely caused by human activity, and long-run analysis shows a one percentage point increase in village poverty corresponds to roughly a 20 percent increase in the probability of fire (10). The season escalated faster than suppression could scale, with burned area jumping from roughly 109,000 hectares in July to about 1.32 million hectares in August, and fire emissions running 273 percent above the seasonal average in early September. Even where flames are gone, embers survive below the surface, so wetting and cooling continue at sites already declared extinguished. Are there any evacuation orders or emergency alerts in place? Indonesian authorities have placed the worst-affected provinces under formal emergency alert status. Jambi has maintained a karhutla Emergency Alert status running from April 27 through November 30, 2026, with Tanjung Jabung Timur Regency under its own alert. Central Kalimantan's provincial Emergency Alert extends through October 31, 2026, and covers districts including East Kotawaringin, Kapuas, Sukamara, Seruyan, Palangka Raya, and West Kotawaringin. South Kalimantan declared an emergency alert for fire and drought from July 6 through October 31, 2026, while West Kalimantan has held provincial alert status since February 2 with an emergency response period layered on top of it (11). Rather than broad mandatory evacuations, authorities have focused on sheltering, mask distribution, and medical surge capacity. Nearly a million masks and hundreds of oxygen concentrator units have been distributed to affected residents, and thousands of medical workers have been deployed, with additional personnel dispatched as needs are identified. Schools across Borneo and Sumatra have shifted to remote learning, nine national parks have closed, and flights have been delayed because of heavy smoke (12). Disaster officials have proposed smoke-free, accessible shelters, evacuation routes, and visual or text alerts for vulnerable residents. Analysts have also called for a national disaster declaration and evacuation support for vulnerable groups, estimating that 17.3 million people across 12 provinces could be affected by acute respiratory infections (13). Residents should monitor air quality and official notices, limit outdoor activity during heavy haze, keep windows and doors closed, wear a well-fitted respirator outdoors, and report signs of fire immediately.

Dangerous heat is forecast across California, with Southern California facing an extended hot spell. Find out more about the California heatwave.

","Why is there a heatwave in the Southwest? The heatwave is driven by a strong ridge of high pressure over the eastern Pacific and the West Coast. High pressure causes air to sink and warm as it descends. The ridge is forecast to stay in place for an unusually long time, which is why the heat could last well into October. Light offshore winds are adding to the heat. These winds blow from the inland deserts toward the ocean, pushing hot, dry air all the way to the coast. They also limit the marine layer of clouds and fog that normally keeps coastal areas mild in autumn. Unusually warm ocean water is also playing a role. Sea surface temperatures along the Southern California and Baja California coastlines are near record highs. This weakens the cooling effect the ocean usually provides and keeps nighttime temperatures high. The heat also follows an exceptionally hot summer, with August 2026 ranking as the warmest on record in several Southern California counties (1). Which cities or areas are affected by the heatwave? The heatwave is affecting large parts of the Southwest, including the following cities and areas: Los Angeles Ventura Santa Barbara Orange County Inland Empire San Diego Central Coast San Joaquin Valley Sacramento Valley San Francisco Bay Area Triple-digit highs are expected to be widespread in the Inland Empire and inland valleys, while coastal areas will see highs in the upper 80s and low 90s. Beyond California, Las Vegas, Reno, and Phoenix will also see warmer-than-usual weather, and heat alerts could expand to Nevada and Arizona if temperatures continue to rise (2). How long will the heatwave last? The heatwave began on Friday, October 2, and is expected to last through at least the end of next week. The first peak is expected over the weekend of October 3 and 4, when highs could reach up to 102°F in parts of Southern California. The heat is not expected to ease after the weekend. According to the National Weather Service, offshore winds and persistent high pressure will continue through the week (3). Some relief may arrive late next week, with gradual cooling expected to begin around Friday, October 9. An upper-level trough bringing tropical moisture could lower temperatures further over the weekend of October 10 and 11. Are there any alerts in place? The National Weather Service has issued an extreme heat warning for the coast and valleys of Los Angeles, Ventura, Santa Barbara, Orange, San Diego, Riverside, and San Bernardino counties. The warning runs from 10 A.M. Friday, October 2, to 8 P.M. Thursday, October 8, and may be extended if the heat continues. Highs are expected to range from the mid 80s at the coast to 105°F inland, with overnight lows staying in the 70s. Shorter heat advisories are also in effect for the Central Coast, the San Joaquin Valley, and the San Francisco Bay Area from October 3 to 4, and for the Sacramento Valley from October 3 to 5. Gusty winds combined with low humidity raise the risk of wildfires, and smoke from any new fires could quickly worsen local air quality. Residents should find out where their local cooling centers are and be ready for possible power outages (4).","

Airborne pollutants can distract in-school learning and compromise student health. Learn about the far-reaching effects of poor air quality in classrooms internationally.

","As autumn approaches and schools are preparing to begin sessions, air quality can be a hidden deterrent, impacting student learning and engagement globally. Depending on school location and regional environment, airborne pollutants could be produced at elevated levels and invade indoor classroom air. Protecting student health through clean indoor air secures productive learning spaces. By understanding the different types of classroom pollutants, associated health implications, and joint parent-educator clean air efforts, students can breathe healthier air with no learning disruptions. What airborne pollutants can be found in classrooms? School location and the surrounding outside air quality environment can have a great impact on various levels of airborne pollutants. For instance, daycares located in populous urban cities may experience heightened levels of traffic emissions, while schools neighboring rural areas could see increased wildfire risk and allergen activity. These air quality events can harbor a wide range of unhealthy pollutant particles, such as: Smoke Pollen Pet dander Gases Odors Volatile organic compounds (VOCs) PM2.5, particulate matter down to 2.5 microns in size PM10, particulate matter down to 10 microns in size With multiple students per class and multiple classrooms within schools, airborne pollutants can be easily knocked into the air throughout the day and transferred from one individual to the next. According to Harvard University, synthetic carpets and dyes schools commonly use have been known to release airborne chemicals, impacting student health (1). CO2, an odorless invisible gas, can also be released through vehicle exhausts in neighboring streets, wildfire smoke, and indoor building vents. Air quality can be infectious as well. Bacterial and viral particles can pass between individuals and cause elevated risks for illness within larger crowds. Airborne viruses, such as SARS- CoV-2 and influenza, can spread through close-contact exposure, especially in stale indoor environments. SARS- CoV-2 is the virus that leads to the COVID-19 disease. How does air pollution impact learning? Air pollution impacts critical areas of student learning, including attendance levels, cognitive function, and test scores. In a survey of studies mostly drawn from urban schools in countries including the U.S., the UK, Sweden, and Brazil, it was found that long-term exposure and higher peaks in pollution could impact school performance and outcomes. This was especially true in schools affected by socioeconomic factors (2). A paper published in 2025 found that a 10 µg/m3 increase in PM2.5 exposure in an urban California school district caused a 5.7% increase in full-day student absences and a 28% increase in office referrals over a three-day window (3). The same rise in pollution levels also increased teacher absences due to illness by 13.1%. A study published in the European Journal of Pediatrics reviewed cognitive function in school age children at schools affected by traffic-related pollutants (4). Analysis found that exposure to these pollutants resulted in lower verbal comprehension in girls, while boys experienced a reduced working memory. Between 2001 and 2018, researchers tracked 2.8 million public school students in North Carolina. This large representation of students spanning the student’s entire time in public schools confirmed that exposure to PM2.5 played a negative role in standardized test scoring (5). Can airborne pollutants impact adolescent health? Yes. Aside from bacterial and viral illnesses, airborne pollutants have been linked to elevated health risks and symptoms that disrupt personal learning and productivity. A 2019 study found that even short-term exposure to airborne pollutants increased the risk for adolescent youth to be hospitalized for mental health concerns, such as intense stress, sadness, anxiety, and harmful thoughts or behaviors (6). Air pollution has a demonstrated, strong impact on children’s lung development. Children living London were found to have much smaller lungs than those of their peers living in Luton, England due to exposure to traffic-sourced air pollution. However, a 2026 study found a decline in childhood lung impairment following the establishment of London’s Ultra Low Emission Zone (ULEZ). Children ages 6-9 years old in London were found to have seen accelerated lung growth compared to the control group in Luton. The London children also experienced an improvement in clinically impaired lung function, dropping from 14% to 9%. Poor air quality can have prolonged effects on developing children and sensitive groups, exacerbating pre-existing symptoms and conditions. Another 2019 research study discovered a link between school absences and asthma, specifically noting urban locations and pollution (7). In the U.S. alone, almost 8,000 public schools are within 500 feet of highways, truck routes, and other traffic-heavy roads, elevating PM2.5 levels within the region of these learning spaces (8). School staff health is also impacted by airborne pollutants. Teachers and staff may experience short- and long-term health problems from poor indoor air quality, ranging from coughing, sneezing, and headaches to more serious health outcomes, like respiratory tract infection and disease and asthma (9). Air pollution affects schools internationally Air pollution is a global issue and schools can experience exacerbated pollutants levels by environmental factors unique to the location. In Delhi, India, some schools reported a shift to hybrid learning systems due to elevated unhealthy pollutant levels from ongoing traffic emissions and urbanization (10). On the days kids are in-person for school, bus transportation could be barred completely, and outdoor recess time can be limited (11). City-wide pollution depends on systematic change and community action for air quality improvements. In Beijing, China, persistent urban air pollution concerns from parents pushed several schools to adopt air cleaning technology. The Beijing Municipal Education Commission came to the decision in 2017 to implement air purifiers across the school district, as several private schools within the city already had integrated clean air systems built (12). In Ontario, Canada, modern federal government aid has supported the reformation of ventilation systems in 72 school boards within the province, as a response from COVID-19 resilience programs (13). According to a 2011 research study, about 16% of primary public schools across Canada’s 10 most populous cities were located near major highways (14). In Melbourne, Australia, in-school programs and new government support opportunities are driving air quality changes within local communities (15)(16). According to a 2024 climate report, one in six Australian schools and childcare centers were located in close proximity to busy roadways, increasing premature health risks and respiratory symptoms (17). How to reduce unhealthy pollutants Air cleaning tools provide optimized support in minimizing airborne pollutant exposure and contagious spread of viral particles. HyperHEPA air purifiers contain maximized filtration, capturing 99.5% of ultrafine pollutants down to 0.003 microns in size, such as smoke, pollen, and particulate matter. Extended runtimes and automated air cleaning devices can be effective for learning spaces as airborne pollutants can disrupt teaching at any time. Schools can join the Clean Air Schools program to help foster safer, healthier learning environments for students. In California, home to the largest number of Clean Air Schools in the country, some students are already benefitting from cleaner air. A pilot study by the South Coast Air Quality Management District (SCAQMD) demonstrated that low-cost, high efficiency HVAC filters removed up to 90% of ultrafine particles and diesel particulate matter from indoor air in three schools near refineries, freeways, and industrial facilities. Cleaner indoor air means reduced absenteeism as well. Through a combination of source control, proper ventilation, and effective air filtration, schools can increase classroom attendance. This can mean increased school funding where funds are linked to lowered absenteeism and better Average Daily Attendance (ADA) (18). Socio-economic disadvantaged and pollution impacted schools can also apply for grant funding, through the Clean Air for Kids initiative from the Foundation for Clean Air. What can schools doSchool staff and district officials can make an impactful difference in student health between every classroom with the proper integrated air cleaning technology and awareness. Implementing advanced school-wide filtration alongside air quality event awareness can help protect student and staff well-being, such as: Join the Schools4Earth program Become a Clean Air School Apply for Clean Air for Kids funding if applicable Open school-wide windows and doors for maximized ventilation when the air is clean Host district meetings or open inquiry drop boxes to collect student health questions and air quality concerns Routinely sanitize commonly used surfaces Avoid scented chemical cleaning aerosols Open classroom windows for maximized airflow ventilation, when the outdoor air is clean Incorporate air quality monitoring and pollutant effects into educational lessons plans What can educators do Teachers and educators have the power to enact positive air quality changes within classrooms and learning spaces. By utilizing air quality innovations and daily clean air methods, students can feel inspired and learn more about environmental awareness, such as: Apply for Clean Air for Kids funding Equip indoor air quality monitors with real-time visual maps Utilize HyperHEPA air cleaning devices for maximized pollutant filtration Routinely sanitize commonly used surfaces Avoid scented chemical cleaning aerosols Open classroom windows for maximized air flow ventilation Incorporate air quality monitoring and pollutant effects into educational lessons plans What can parents doParents, relatives, and community members can take initiatives and plan ahead for students to transition smoothly and safely into new indoor environments. Practicing air-conscious lifestyle choices alongside at-home filtration ensures students feel prepared and aware of air quality conditions, including: Ensure schools are equipped with indoor and outdoor air quality monitors to spread awareness Keep KN95 masks on hand during wildfire smoke events Donate air purification devices to classrooms in public schools Routinely sanitize school backpacks and clothes that can track in pollutants Discuss specific air quality or health needs with educators to ensure proper childcare Drive an electric vehicle or utilize school bus drop-offs to limit traffic emissions Attend school district meetings to contribute to air quality improvements Clean air preparation and lifestyle choices for students can help build environmental awareness and secure healthy breathing conditions both in school and at home. Conclusion Schools should feel like safe, productive learning spaces no matter the location or city it resides in. Securing clean air quality and practicing air-conscious choices can be impactful steps to creating a healthy environment for students this upcoming school year. With the Clean Air School certification with monitoring tools, air quality can be implemented within daily schedules or even educational lesson plans. By leveraging air quality data, technology, and filtration, student health protection can be maximized and fit seamlessly into environmental education.","

In the U.S. alone, almost 8,000 public schools are within 500 feet of highways, truck routes, and other traffic-heavy roads, elevating PM2.5 levels within the region of these learning spaces (8).

School staff health is also impacted by airborne pollutants. Teachers and staff may experience short- and long-term health problems from poor indoor air quality, ranging from coughing, sneezing, and headaches to more serious health outcomes, like respiratory tract infection and disease and asthma (9).

Air pollution affects schools internationally

Air pollution is a global issue and schools can experience exacerbated pollutants levels by environmental factors unique to the location.

In Delhi, India, some schools reported a shift to hybrid learning systems due to elevated unhealthy pollutant levels from ongoing traffic emissions and urbanization (10). On the days kids are in-person for school, bus transportation could be barred completely, and outdoor recess time can be limited (11). City-wide pollution depends on systematic change and community action for air quality improvements.

In Beijing, China, persistent urban air pollution concerns from parents pushed several schools to adopt air cleaning technology. The Beijing Municipal Education Commission came to the decision in 2017 to implement air purifiers across the school district, as several private schools within the city already had integrated clean air systems built (12).

In Ontario, Canada, modern federal government aid has supported the reformation of ventilation systems in 72 school boards within the province, as a response from COVID-19 resilience programs (13). According to a 2011 research study, about 16% of primary public schools across Canada’s 10 most populous cities were located near major highways (14).

In Melbourne, Australia, in-school programs and new government support opportunities are driving air quality changes within local communities (15)(16). According to a 2024 climate report, one in six Australian schools and childcare centers were located in close proximity to busy roadways, increasing premature health risks and respiratory symptoms (17).

How to reduce unhealthy pollutants

Air cleaning tools provide optimized support in minimizing airborne pollutant exposure and contagious spread of viral particles. HyperHEPA air purifiers contain maximized filtration, capturing 99.5% of ultrafine pollutants down to 0.003 microns in size, such as smoke, pollen, and particulate matter. Extended runtimes and automated air cleaning devices can be effective for learning spaces as airborne pollutants can disrupt teaching at any time.

Schools can join the Clean Air Schools program to help foster safer, healthier learning environments for students. In California, home to the largest number of Clean Air Schools in the country, some students are already benefitting from cleaner air. A pilot study by the South Coast Air Quality Management District (SCAQMD) demonstrated that low-cost, high efficiency HVAC filters removed up to 90% of ultrafine particles and diesel particulate matter from indoor air in three schools near refineries, freeways, and industrial facilities.

Cleaner indoor air means reduced absenteeism as well. Through a combination of source control, proper ventilation, and effective air filtration, schools can increase classroom attendance. This can mean increased school funding where funds are linked to lowered absenteeism and better Average Daily Attendance (ADA) (18).

Socio-economic disadvantaged and pollution impacted schools can also apply for grant funding, through the Clean Air for Kids initiative from the Foundation for Clean Air.

What can schools do
School staff and district officials can make an impactful difference in student health between every classroom with the proper integrated air cleaning technology and awareness. Implementing advanced school-wide filtration alongside air quality event awareness can help protect student and staff well-being, such as:

Join the Schools4Earth program
Become a Clean Air School\n
Apply for Clean Air for Kids funding if applicable
Open school-wide windows and doors for maximized ventilation when the air is clean
Host district meetings or open inquiry drop boxes to collect student health questions and air quality concerns
Routinely sanitize commonly used surfaces
Avoid scented chemical cleaning aerosols
Open classroom windows for maximized airflow ventilation, when the outdoor air is clean
Incorporate air quality monitoring and pollutant effects into educational lessons plans
\n

What can educators do
Teachers and educators have the power to enact positive air quality changes within classrooms and learning spaces. By utilizing air quality innovations and daily clean air methods, students can feel inspired and learn more about environmental awareness, such as:

Apply for Clean Air for Kids funding
Equip indoor air quality monitors with real-time visual maps
Utilize HyperHEPA air cleaning devices for maximized pollutant filtration
Routinely sanitize commonly used surfaces
Avoid scented chemical cleaning aerosols
Open classroom windows for maximized air flow ventilation
Incorporate air quality monitoring and pollutant effects into educational lessons plans

What can parents do
Parents, relatives, and community members can take initiatives and plan ahead for students to transition smoothly and safely into new indoor environments. Practicing air-conscious lifestyle choices alongside at-home filtration ensures students feel prepared and aware of air quality conditions, including:

Ensure schools are equipped with indoor and outdoor air quality monitors to spread awareness
Keep KN95 masks on hand during wildfire smoke events
Donate air purification devices to classrooms in public schools
Routinely sanitize school backpacks and clothes that can track in pollutants
Discuss specific air quality or health needs with educators to ensure proper childcare
Drive an electric vehicle or utilize school bus drop-offs to limit traffic emissions
Attend school district meetings to contribute to air quality improvements

Clean air preparation and lifestyle choices for students can help build environmental awareness and secure healthy breathing conditions both in school and at home.

Conclusion

Schools should feel like safe, productive learning spaces no matter the location or city it resides in. Securing clean air quality and practicing air-conscious choices can be impactful steps to creating a healthy environment for students this upcoming school year. With the Clean Air School certification with monitoring tools, air quality can be implemented within daily schedules or even educational lesson plans.

By leveraging air quality data, technology, and filtration, student health protection can be maximized and fit seamlessly into environmental education.

Not sure where your air purifier should go in the living room? The answer depends less on the spot and more on whether it's properly sized for the space. Here's how to get both right.

","Where you put an air purifier in a living room matters, but not as much as whether the unit is properly sized and running at an adequate fan speed for the room. Get sizing right, and placement has real flexibility. Get it wrong, and where you put the purifier becomes the deciding factor in whether you're breathing cleaner air at all, because an undersized or under-powered unit can't rely on general circulation to reach the whole room.

Discover the most effective place to put your air purifier in the bedroom.

","The best place to put an air purifier in a bedroom is close enough to improve the air you breathe while sleeping, but positioned so clean air can circulate freely throughout the room (1). Because people spend long, uninterrupted hours in bedrooms, air purifier placement can influence how effectively airborne particles and allergens are removed from the sleeping environment. Clean air and the sleeping environment Bedrooms are where people typically spend the longest uninterrupted periods indoors, making them critical spaces for clean air—especially for those with allergies, asthma, or sensitivities to dust, pet dander, or outdoor pollutants. Because people spend extended periods breathing the same indoor air while sleeping, air purifier placement can influence how effectively these particles are removed from the sleeping environment overnight. Reducing indoor pollution sources, improving airflow and ventilation by opening windows when outdoor air quality allows, and using high-efficiency filtration can all influence how particles accumulate indoors. For example, reducing the use of heavily scented products, improving ventilation when outdoor air quality is good, and limiting indoor smoke or dust sources can help reduce the amount of airborne particles circulating through a bedroom. Why airflow matters in a bedroom Air purifiers work by pulling polluted air through a filtration system and recirculating cleaned air back into the room. When airflow is blocked by walls, furniture, or bedding, particles can remain concentrated in parts of the room instead of circulating toward the purifier. Because airflow influences how particles move through a bedroom, purifier placement can affect how efficiently airborne particles are removed from the sleeping environment. Common mistakes to avoid in bedroom purifier placement Many people unknowingly reduce their air purifier’s effectiveness by making these placement errors: In a corner or behind furniture: This blocks airflow and limits the purifier’s reach. Keep it in an open area where air can circulate freely. Too close to electronics or heat sources: Avoid placing it near TVs, lamps, or heating vents, as heat can affect performance or pose a safety risk. Near open windows during high-pollution times: While ventilation is good, outdoor allergens or smog can enter and overwhelm the purifier. Close windows during allergy season, wildfires, or peak traffic hours. Ignoring filter maintenance: A clogged filter reduces airflow and efficiency. Check and replace filters as recommended, especially in high-dust environments. If your bedroom is large or irregularly shaped, consider a purifier with strong airflow or use a second unit to ensure even coverage. For children’s rooms, place the purifier out of reach but where it can still circulate air effectively. Frequently Asked Questions Should I run my air purifier all night in the bedroom? Yes. Running it continuously on a low or night mode ensures clean air throughout your sleep, which is especially beneficial for allergy or asthma sufferers. Most modern purifiers are quiet enough not to disrupt rest. Can I place the air purifier on the floor next to my bed? Yes. Placing an air purifier on the floor near the bed can be effective, provided airflow is not blocked by furniture or bedding. Keep enough space around the purifier for air to circulate freely. How far from the bed should the air purifier be? Aim for 3–6 feet away, positioned so clean air flows toward your breathing zone without blowing directly on you. This balances effectiveness and comfort. Does the air purifier need to be centered in the room? Not necessarily. Prioritize placing it near your bed but with unobstructed airflow. For larger bedrooms, a central location can help, but proximity to your sleeping area is most important. Can I use an air purifier in a small bedroom? Yes. Choose a model sized for your room and place it where airflow isn’t blocked. Even in smaller bedrooms, compact air purifiers can help improve air quality when positioned with unobstructed airflow. Conclusion Air purifier placement can influence how effectively fine particles and allergens are removed from the air you breathe while sleeping. Positioning the purifier where airflow remains unobstructed helps improve circulation and reduce indoor particle buildup over time. Indoor air quality is often managed through a combination of source control, ventilation, and filtration. Combined with regular cleaning and reduced indoor pollution sources, proper air purifier placement can help create a cleaner sleeping environment and improve the air circulating through your breathing zone overnight.","

Many people unknowingly reduce their air purifier’s effectiveness by making these placement errors:

In a corner or behind furniture: This blocks airflow and limits the purifier’s reach. Keep it in an open area where air can circulate freely.
Too close to electronics or heat sources: Avoid placing it near TVs, lamps, or heating vents, as heat can affect performance or pose a safety risk.
Near open windows during high-pollution times: While ventilation is good, outdoor allergens or smog can enter and overwhelm the purifier. Close windows during allergy season, wildfires, or peak traffic hours.
Ignoring filter maintenance: A clogged filter reduces airflow and efficiency. Check and replace filters as recommended, especially in high-dust environments.
\n

If your bedroom is large or irregularly shaped, consider a purifier with strong airflow or use a second unit to ensure even coverage. For children’s rooms, place the purifier out of reach but where it can still circulate air effectively.

Frequently Asked Questions

Should I run my air purifier all night in the bedroom?

Yes. Running it continuously on a low or night mode ensures clean air throughout your sleep, which is especially beneficial for allergy or asthma sufferers. Most modern purifiers are quiet enough not to disrupt rest.

Can I place the air purifier on the floor next to my bed?

Yes. Placing an air purifier on the floor near the bed can be effective, provided airflow is not blocked by furniture or bedding. Keep enough space around the purifier for air to circulate freely.

How far from the bed should the air purifier be?

Aim for 3–6 feet away, positioned so clean air flows toward your breathing zone without blowing directly on you. This balances effectiveness and comfort.

Does the air purifier need to be centered in the room?

Not necessarily. Prioritize placing it near your bed but with unobstructed airflow. For larger bedrooms, a central location can help, but proximity to your sleeping area is most important.

Can I use an air purifier in a small bedroom?

Yes. Choose a model sized for your room and place it where airflow isn’t blocked. Even in smaller bedrooms, compact air purifiers can help improve air quality when positioned with unobstructed airflow.

Conclusion

Air purifier placement can influence how effectively fine particles and allergens are removed from the air you breathe while sleeping. Positioning the purifier where airflow remains unobstructed helps improve circulation and reduce indoor particle buildup over time.

Indoor air quality is often managed through a combination of source control, ventilation, and filtration. Combined with regular cleaning and reduced indoor pollution sources, proper air purifier placement can help create a cleaner sleeping environment and improve the air circulating through your breathing zone overnight.

Air purifiers can combat secondhand smoke with the right specifications and filters. Learn what types of air purifiers can properly filtrate smoke.

","Yes, air purifiers can help reduce secondhand smoke indoors—but not every air purifier is designed to handle smoke effectively. Smoke contains both fine particles and smoke-related gases, which is why some filtration systems are better suited for smoke exposure than others. Secondhand smoke particles can remain suspended in indoor air long after smoking stops, while smoke residue can continue settling onto walls, fabrics, and other surfaces over time. Reducing exposure depends on a combination of source control and ventilation. Filtration is most effective when paired with efforts to limit the amount of smoke entering or remaining in the indoor environment. How secondhand smoke spreads indoors Secondhand smoke comes from two main sources: smoke exhaled by a smoker and smoke released from a burning cigarette or cigar. Smoke released directly from a burning cigarette, often called sidestream smoke, is considered especially hazardous because it contains high concentrations of toxic chemicals. Between 2015 and 2018, more than 1 in 5 U.S. adults were exposed to secondhand smoke (1). Exposure can continue in different ways depending on how smoke moves through the environment: Firsthand/Mainstream smoke: Smoke inhaled directly by a smoker (2). Secondhand/Sidestream smoke: Smoke inhaled by nearby non-smokers, often lingering indoors long after smoking occurs. Thirdhand smoke: Smoke residue that settles onto surfaces, fabrics, walls, and clothing over time. Firsthand, secondhand, and thirdhand smoke all contain PM2.5 and PM10 particles. PM2.5 refers to particles measuring 2.5 microns or smaller, while PM10 includes larger particles up to 10 microns in diameter. These particles can remain suspended in the air and may affect human health when inhaled over time. Why lingering smoke remains a health risk Secondhand smoke exposure is not limited to the moment someone is actively smoking. Smoke particles and chemical residue can remain indoors, increasing the likelihood of repeated exposure over time. On average, 300,000 children under 18 months of age are diagnosed with lower respiratory tract infections every year in the U.S. as a direct result of secondhand smoke exposure (3). Secondhand smoke has also been linked to childhood leukemia and sudden infant death syndrome. For adults, long-term secondhand smoke exposure can lead to stroke, nasal irritation, asthma, and reproductive effects in women (4). Secondhand smoke particles contain over 7,000 toxic chemicals and 70 carcinogens contributing to these health effects (5), including: Arsenic Formaldehyde Lead Nickel Benzene Secondhand smoke exposure is dangerous and can cause serious health risks, especially for children and sensitive groups. Smoking indoors can significantly worsen these conditions. How secondhand smoke affects indoor air quality Secondhand smoke particles tend to linger, causing unhealthy air quality in both indoor and outdoor spaces if there is a lack of proper filtration, ventilation, or routine cleaning. Smoke particles can continue circulating indoors long after smoking occurs, especially in spaces with limited airflow or ventilation. Outdoor Lit cigarettes and secondhand smoke can affect shared outdoor spaces by leaving behind smoke residue and increasing nearby exposure. In shared patios or balconies, secondhand smoke produces tobacco particles that stick to furniture and surfaces, leaving behind odors and increasing exposure risk. Smoking in outdoor dining spaces or restaurants can cause secondhand smoke exposure for staff, customers, and those walking by. Indoor When tobacco smoke is exhaled indoors, smoke residue and toxins can stick to surfaces, such as furniture, clothing, tabletops, walls, and fabrics. Without regular cleaning, these harmful smoke biproducts can continue accumulating over time. How filtration helps reduce secondhand smoke Reducing secondhand smoke exposure often depends on combining filtration with broader indoor air quality practices. Air purifiers equipped with HyperHEPA filtration are engineered to capture particles as small as 0.003 microns with 99.5% efficiency, capable of filtering firsthand and secondhand smoke from indoor air.Along with HyperHEPA technology, some air purifiers utilize additional gas phase filtration systems to further capture gases and odors associated with tobacco smoke. Some systems, like IQAir’s GC MultiGas XE Air Purifier, are designed to address smoke-related particulates, gases, and odors together. Proper filtration can help reduce secondhand smoke exposure, but achieving a truly smoke-free environment also depends on daily practices and improved ventilation. How to create a smoke-free environment Creating a smoke-free environment depends on more than filtration alone. Source control, ventilation, regular cleaning, and air filtration all play a role in reducing lingering smoke particles indoors. Source control: Avoiding smoking entirely is the most effective way to reduce secondhand smoke exposure. Additional steps can include establishing smoke-free policies, creating designated outdoor smoking areas, and routinely cleaning surfaces. Ventilation: Open windows if smoking occurs indoors, install fans in outdoor smoking areas, and be cautious of smoke from neighbors by closing windows when needed. Air Filtration: Utilize air purifiers for commonly used spaces and use air quality monitors to track changes in indoor air quality. Frequently Asked Questions Do air purifiers help with firsthand, secondhand, and thirdhand smoke? Yes, air purifiers can help remove firsthand, secondhand, and thirdhand smoke. Air purifiers primarily address airborne particles, such as firsthand and secondhand smoke. Reducing thirdhand smoke exposure often requires regular cleaning of surfaces and fabrics where smoke residue accumulates. How often should I change a HyperHEPA filter? Filters should be replaced typically every 3-4 years for air purifiers accommodating large rooms. For personal or desk air purifiers, filters may need to be changed more frequently. What causes secondhand smoke exposure? Secondhand smoke exposure is most commonly a direct result of being near someone actively smoking. If you were next to an individual who lit a cigarette and exhaled smoke, you are likely to inhale secondhand smoke particles. The smoke particles that may cling to clothing or nearby surfaces would be considered thirdhand smoke. How do I know if I have been exposed to secondhand smoke? Common immediate symptoms of secondhand smoke exposure include eye or nasal irritation, coughing, nausea, and headaches. Various visual or scent clues could be present as well, ranging from lingering smoke in the air to burnt or unpleasant smells. Conclusion Secondhand smoke can continue affecting indoor air quality long after smoking occurs, especially in enclosed spaces with limited ventilation. Smoke particles and residue can remain suspended in the air or settle onto surfaces over time, increasing the likelihood of repeated exposure. Reducing exposure often depends on a combination of source control, ventilation, filtration, and regular cleaning.

Whether you run your air purifier all day and night or just during certain times, find the optimal length for air purifier use.

","Most air purifiers are designed for continuous operation and are generally more effective at maintaining cleaner indoor air when left running consistently. Since airborne pollutants can continuously re-enter indoor spaces, steady air cleaning helps maintain more stable indoor conditions over longer periods. How does room size impact air purifier runtimes? Room size and daily activity levels both affect how quickly airborne particles can accumulate indoors. Larger rooms and busier spaces may require longer operation in order to maintain cleaner indoor air (1). Suggested runtimes for maintaining cleaner indoor air include (2): Small room/Low activity: 6-8 hours Medium room: 8-12 hours Large room/High activity: 24 hours Air purifier placement can also affect how efficiently air moves and circulates throughout a room. Positioning an air purifier in an open area and minimizing outdoor pollutant exposure can help keep indoor air cleaner more consistently. How long should an air purifier run during periods of high pollution? Continuous air cleaning is recommended when outdoor pollution levels are elevated, particularly during wildfire events, dust storms, or heavy pollen seasons. During these events, airborne particles can enter indoor spaces in higher concentrations. Indoor particle levels may rise quickly, especially in spaces with frequent outdoor air exchange or high daily activity. Keeping windows closed during pollution events can help limit the amount of outdoor pollution entering indoor spaces. Continuous operation at lower fan speeds can also help keep indoor air cleaner more consistently over longer periods (3). What makes an air purifier suitable for continuous use? Most air purifiers use mechanical filtration, which relies on a fan to pull air through a particle filter. Mechanical filtration is one of the most common approaches for long-term indoor air cleaning. However, not all air purifiers are designed for continuous operation. Some air cleaning technologies, such as ozone generators and certain ionizing systems, may introduce ozone or other byproducts into indoor spaces and are generally not recommended for long-term continuous use. Certain features can make an air purifier well-suited for continuous operation, including: High-efficiency filter: HyperHEPA filtration can help capture ultrafine airborne particles over long periods of operation. Activated carbon filtration: Carbon-based filters can help reduce smoke-related gases, VOCs, and household odors. Safety certifications: Choose an air purifier with a STAR, ETL, or UL safety certification to ensure the product meets electrical and operating standards. Automated controls and fan speeds: Lower fan speeds can help maintain quieter, more energy-efficient long-term operation. Room size recommendations: Pay attention to recommended room sizes on air purifier packaging to ensure optimal air cleaning. Long-term performance also depends on regular cleaning and routine filter maintenance. How long do air purifier filters last? Air purifier filters are designed to capture airborne particles continuously over long periods of operation. As particles accumulate on the filter surface, filtration efficiency can remain stable or even improve in some cases through a process sometimes referred to as “caking,” where trapped particles help capture additional pollutants. Over time, however, excessive particle buildup can begin restricting airflow and force the system to work harder to move air through the filter. Routine filter replacement helps maintain balanced airflow, long-term performance, and energy efficiency during continuous operation. IQAir filtration systems use multiple filter stages with replacement intervals that vary depending on the filter type and operating conditions, including: HyperHEPA Particle Filter ~ 3-4 years V5-Cell Gas & Odor Filter ~ 1-2 years GC HyperHEPA Pre-Filter ~ 1 year GC Gas & Odor Cartridge Filter ~ 2-3 years Filtration performance over time can also be evaluated using Cumulative Clean Mass (CCM), which measures how much particulate matter a filter can capture while maintaining effective long-term operation. Some systems are also evaluated using Clean Air Delivery Rate (CADR), which measures how quickly airborne particles are removed from a space. However, CADR alone does not fully describe long-term filtration stability, airflow performance, or energy efficiency. Does long-term air purifier usage raise electrical bills? To conserve energy while maintaining long-term operation, automated air purifier features are key when operating on a daily schedule. For air purifiers such as Atem Earth, smart self-adjustable fan and filter monitor features help ensure electrical waste is reduced automatically. Smart controls and adaptive fan settings can help reduce unnecessary energy use during long-term operation. For the Atem X air purifier, the Bluetooth controls and built-in air quality sensors help manage energy use while adjusting operation based on indoor conditions. FAQs Should I run an air purifier overnight? Yes. Airborne particles continue circulating indoors overnight, particularly in enclosed spaces with limited ventilation, so air filtration throughout the night can help maintain good indoor air quality. Is it bad to run an air purifier 24 hours a day? No. Longer operation allows air purifiers to capture airborne pollutants more consistently over time. Continuous operation may slightly increase electricity use, particularly at higher fan speeds. What size air purifier is right for my space? Look for manufacturer room size recommendations, as most air purifier packaging details the recommended room dimensions the system can accommodate. Generally, personal air purifiers are best for smaller spaces or desks, while larger floor-based air purifiers are suitable for shared spaces and larger rooms. Conclusion Indoor air quality changes throughout the day, even when rooms appear clean or unoccupied. Because airborne particles continuously circulate through indoor environments, consistent air cleaning is often more effective than short periods of intermittent use. For many homes and shared spaces, continuous operation at lower fan speeds provides the most stable long-term reduction of airborne particles while maintaining energy efficiency and filter performance.","

Air purifiers may not function properly if placed in an improper space. Discover the ideal air purifier for your space, tailored to meet your needs.

","Air purifiers are powerful air cleaning tools that remove airborne pollutants and harmful chemicals from indoor spaces through multilayer filtration. However, not every air purifier is fit for any sized space. Room dimensions and the environment air purifiers are housed in can greatly impact the performance and filtration efficiency of the device. Understanding optimal air purifier sizes, environments, and locations helps ensure air cleaning systems function properly and are filtrating invisible pollutants with maximum efficiency. What is the best air purifier for my room size? Air cleaning systems are designed to cater to specific types of environments and room sizes to ensure airborne pollutants are properly filtrated and cleaned. Following suggested room air purifier pairing maximizes filtration efficiency and helps secure comprehensively clean air quality. Optimal room size and air purifier type pairings include: Portable air purifiers: Best fitted for small rooms or spaces that are temporarily occupied, such as hotel rooms, personal vehicles, and public bathrooms. Tabletop air purifiers: Best fitted for personal spaces or small rooms with low activity, such as desks, workspaces, or bedrooms. Floor-standing air purifiers: Best fitted for large rooms with high activity or pollutant emissions, such as living rooms, kitchens, and game rooms. HVAC air cleaning systems: Best fitted for whole-house utilization, capturing pollutants through various airducts and vents in a home. Check for suggested dimensions or types of rooms on the air cleaning device’s packaging or instruction manual. Mismatched or unsuitable room and air purifier pairings can lead to compromised air quality conditions, causing elevated health risks and pollutant particle exposure. How does room size impact air purifiers? Improper air purifier and room pairings could greatly reduce performance results, leaving particles untreated and personal health potentially compromised. If a room is too large or has too high of daily activity for an air purifier, the system may take longer to filtrate all pollutant particles effectively, resulting in an unstable air quality conditions and more airborne particulate matter. If a space is too small for a large air purifier, excess electrical utilization and higher utility bills could occur when smaller energy-efficient systems can provide sufficient filtration power. The key to securing maximum protection is understanding environment dynamics and the presence of airborne pollutants, as insufficient air purifier and room pairings can lead to unaddressed air quality concerns. What types of particles do air purifiers filter? If placed in an optimal environment, air purifiers can remove various harmful chemicals and airborne pollutant particles such as PM2.5, PM10, and volatile organic compounds (VOCs) – all linked to respiratory symptoms and elevated health risks. PM2.5 is particulate matter up to 2.5 microns in size and PM10 includes particles up to 10 microns. These particle types include various allergens and indoor pollutants including pollen, pet dander, dust, and smoke. To ensure proper air purifier utilization and maximum filtration efficiency, air metrics and measurements are key in quantifying performance results and ensuring optimal room pairings. How to find the most efficient air purifier for a space Air filtration and ventilation metrics allows for air purifiers to be tested for optimal utilization and ensures air cleaning systems are functioning properly and up to industry standards within the indoor space they are housed in (1). By calculating the Clean Air Delivery Rate (CADR), Air Changes per Hour (ACH), and Cumulative Clean Mass (CCM), an air purifier’s performance efficiency can be quantified and measured. The Clean Air Delivery Rate (CADR) measures how quickly an air cleaning tool can remove pollutants and produce clean air quality. CADR is a metric tool for calculating an air purifier’s initial performance power, but does not determine overall system efficiency and should be used in conjunction with other air metrics. Optimal CADR value should be 2/3 of the total room dimensions, often listed on the outside of product packaging. Air Changes per Hour (ACH) measures how many times air particles are replaced in an indoor space within a 60-minute time period. The Centers for Disease Control and Prevention suggests an ACH value of seven or higher as the “best” ventilation efficiency, labeling an ACH value of four as “good” and a six as “better.” Cumulative Clean Mass (CCM) measures how much pollutants and particulate matter can be captured and filtrated before the air cleaning device loses filtration efficiency. CCM is an optimal metric in determining long-term air purifier performance as it measures efficiency duration. Check the outside product packing and look for higher CCM values such as P4 or F4 – the higher the CCM value, the greater the long-term performance of an air cleaning system.

By understanding optimal room pairings and clean air practices, comprehensively clean air quality can be achieved with ease, such as: Pollutant source control: Avoid spraying scented or chemical cleaning products, place air purifiers in high activity rooms, and close windows during harmful outdoor air quality events. Room ventilation: Open windows during high indoor activity, install air quality monitors to know when ventilation is safe, and utilize fans to increase airflow and circulation. Efficient filtration: Check air purifier packaging for high CCM or ACH values, place air cleaning devices away from furniture to avoid blockages, and run air systems on a daily schedule to ensure maximum filtration. Analyzing optimal room and air purifier pairings while employing clean air practices provides a pathway to maximum pollutant protection and efficient filtration power. Frequently Asked Questions (FAQs) What air purifier is best for large spaces and low activity? Floor-standing air purifiers are an excellent choice for large spaces with low activity. Large rooms house an abundance of airborne particles that require sufficient filtration to achieve comprehensively clean air quality. If the space has low activity levels, all-day utilization may not be necessary and just a few hours of runtime could be effective enough to filtrate pollutant particles. What air purifier is best for small spaces and high activity? Table-top or floor-standing air purifiers are both effective choices for small spaces with high activity. Compact, personal spaces can be sufficiently cleaned with extended, daily utilization of smaller air purifier units. The key to address heightened levels of pollutant activity is longer runtimes for air cleaning systems – ideally a 24-hour utilization period would provide maximum protection against harmful particles. How long do air purifier filters last? Air purifier filters can last anywhere between 1-4 years, depending on size, model, and daily utilization. How do I know if an air purifier is right for my space?To verify an air purifier is performing at an optimal efficiency within an indoor space, utilize air metrics such as Cumulative Clean Mass (CCM) and Air Changes per Hour (ACH). CCM measures how many pollutant particles can be captured before an air cleaning system loses efficiency, analyzing long-term performance and longevity. Aim to select systems with a CCM value of P4 or F4 – the higher the P and F values, the greater the filtration power of an air purifier. ACH measures how often air particles within an indoor space can be replaced or cleaned in a 60-minute time period. High ACH values have been linked to respiratory and allergen symptom relief, with a ranking of seven or higher labeled as “best” according to the CDC. Conclusion Air purifiers are effective air cleaning tools that remove airborne pollutants, particulate matter, and pollutants from indoor air, but only when paired properly with an optimal room to house the system.

Air quality could be compromised if air cleaning systems suddenly stop functioning. Learn why your air purifier might not be working and easy fixable solutions to troubleshoot.

","Air purifiers are important indoor tools that remove airborne pollutants and provide clean air quality for large spaces and buildings. In the event an air purifier stops working, air quality may be compromised and pollutant particles could invade homes almost immediately. Air purifier problems may feel sudden—but most of the time the troubles are temporary and can be solved through easy changes to the device or system placement. Here are six common reasons air purifiers may stop working and how to troubleshoot each scenario. Reason 1: Air purifier filter is dirty, clogged, or doesn’t properly fit One of the most common scenarios at-home users run into is that the filters within their air purifiers are dirty or clogged due to prolonged utilization (1). Air purifier filters have lifespans printed on product packaging, detailing to users when the filter should be changed to a new one. Air purifier filters should never be reused and lifespans of the filters could degrade much quicker based on daily utilization. Another reason why air purifiers don’t work is because the filter doesn’t properly fit. This can be because replacement instructions are not followed or most likely because it’s the wrong filter. Be sure to check the filter model is the correct fit for the air purifier device. Also ensure and that all plastic packaging is removed. Incorrect filter models and wrapped product packaging could lead to an improper fit, causing an air purifier to not filter the air properly. Reason 2: Air purifier is not fit for the room dimensions An air purifier could be functioning properly, but the room size the device is placed in impacts an air purifier’s ability to perform. If a small air purifier is placed in a large room, the device may be ineffective in removing all airborne pollutants and wouldn’t be able to filtrate the entire indoor air space. To ensure maximum pollutant protection and proper filtration, check the suggested room size for your air purifier on the product’s packaging. Generally, small tabletop air purifiers should be placed in desk areas or smaller rooms, while floor-standing air purifiers are best fit for larger family-style rooms. Measure room dimensions to ensure air purifiers are a proper fit for the spaces they are housed in. Reason 3: Fan speed is too low While low fan speeds save electrical energy, some spaces may require higher fan settings to effectively remove the maximum number of airborne pollutants. Large spaces or rooms with high activity can produce greater amounts of pollutant particles that low fan speeds may not be equipped to handle. If an air purifier doesn’t improve a room’s air quality, employ medium-to-high power fan settings to increase filtration speed and suction. Set the air purifier to a continuous fan mode to maximize airflow intake throughout the day. Reason 4: Power-saving modes or timers could be inefficient Energy-efficient modes and timers are beneficial in reducing electrical usage, but the settings could impact air purifier performance and suction power. Airborne pollutants never stop invading homes, even at night. Constant usage of sleep mode timers and energy-efficient settings prohibits air purifiers from running consistent filtration cycles. If air quality doesn’t seem to improve with an air purifier, try running the device on high-powered filtration settings throughout the day and night. Allowing an air purifier system to run for longer at higher fan settings may help improve air quality levels and reduce particulate matter. Reason 5: Air purifier placement is blocking airflow The placement of an air purifier is important—if placed incorrectly, airflow could be blocked and the air purifier wouldn’t be able to properly filtrate airborne pollutants (2). Place air purifiers away from walls, furniture, and open windows that could obstruct or interfere with direct airflow. Routinely cleaning an air purifier and brushing through filter holes can help prevent airflow blockages as well. Large particle matter, such as dust clumps and hair, can easily get stuck between filter holes, blocking airflow and other pollutants from getting filtered. Reason 6: Electrical connectivity is poor The source of the issue may not have to come from the air purifier itself, but rather the electrical outlets and cords the device is connected to. Try plugging the air purifier into various different outlets or power cord extensions to see if it could be an electrical plug issue. Check to ensure the air purifier has an appropriate voltage and doesn’t overload the electrical outlets. If multiple outlets are not working, try examining the air purifier to see if there may be any loose wiring or snapped cords that are causing the issue. Make sure the air purifier device is switched on when plugged into an electrical outlet. Methods for proper air purifier utilization Air purifier troubles can be frustrating, especially when problems arise unannounced. However, daily practices and routine cleaning can help reduce any risks of your air purifier running into an issue. From a ventilation and filtration practices to a troubleshoot checklist, helpful air purifier questions and maintenance tasks include: Routine practices: Daily cleaning: Clean air purifier filter holes from large debris, routinely change out filters, and upkeep electrical cords to ensure proper connectivity. Positioned ventilation: Be aware of blockages to the air purifier filter holes, avoid placing devices near open windows, and double check room dimensions are fit for the air purifier. Air filtration settings: Install an air quality monitor to examine clean air results, employ high powered fan speeds, and run air cleaning devices for prolonged periods of time. Troubleshooting checklist: Is the filter clean and properly installed? Is the purifier sized correctly for the room? Is it positioned away from walls and obstructions? Is the fan speed set appropriately for current conditions? Is the power connection secure? Have you tried unplugging and resetting the unit? To avoid compromised indoor air quality, routine practices and running through a troubleshoot checklist are key in isolating air purifier issues and obstacles. Frequently Asked Questions (FAQs) I tried everything, what do I do if my air purifier is still not working?If you have tried multiple troubleshooting methods and the air purifier is still not functioning properly, the issue could be internal and may require in-depth assistance or device replacement. For IQAir air purifier assistance, please submit an online inquiry or schedule a call with an IQAir expert through the “Contact Us” section on our website. How long do air purifier filters last? Air purifier filters can last from 1-4 years, depending on filter model, daily utilization, and environment. Where should I put an air purifier? The most optimal spaces for an air purifier are environments with abundant particulate matter, high daily activity levels, and various exposures to allergens. To avoid performance difficulties, place the air purifier away from walls, furniture, and obstructive household items that could block airflow intake. Open windows directly next to air purifiers may also interfere with the system’s ability to effectively filtrate indoor pollutants. How do I know my air purifier is working?Air purifiers are quiet, yet effective tools in removing particulate matter and airborne pollutants indoors. To verify if an air purifier is working properly, place your hand near the system’s filtration holes and feel to see if the device is suctioning air. Compare and contrast personal allergen symptoms before employing an air purifier and after. To scientifically verify clean air production, employ an air quality monitor and examine if Air Quality Index (AQI) levels improve when using an air purifier. Conclusion Faulty air purifier setup and placement can’t stop clean air quality to be achieved within indoor spaces. To prohibit or solve common connectivity issues for air purifiers, utilize troubleshooting methods to quickly address the problem and continue clean air filtration.

Ever wonder what the varying HEPA filter types do and how they’re different? You’ll find out when you read our new guide to HEPA filtration.

","All air purifiers work to remove airborne pollutants and harmful chemicals through high-efficiency, densely packed filters. However, the filters within air purifiers are comprised of different materials, filtration efficiency, and pollutant removal qualities. Understanding the differences between HEPA filtration systems and the efficiency power they produce allows for educated decision making in selecting a filter with the maximum pollutant protection. What are True HEPA filters? True HEPA filters are standard HEPA filters with a 99.97% removal rate of pollutants up to 0.3 microns in size. True HEPA filters suction harmful pollutant particles from the air through a dense fiber filter, producing clean air and lowering risks for health complications, such as lung cancer, respiratory issues, and heightened allergies.

HEPA and HyperHEPA filters have a dense fiber design that target fine and ultrafine particles, dust, and airborne allergens.

Another key difference is the materials each filter is comprised of—activated carbon filters utilize biodegradable coconut shells or bituminous charcoal, while HEPA filtration systems use fiberglass or synthetic polymers for filtration strength. Despite their vast differences, employing both activated carbon and HEPA filters in homes ensures comprehensive air quality protection.

Choosing the right air filtration system

Safe indoor air quality relies on the removal of all airborne pollutants to ensure maximum protection. Opening windows and monitoring outdoor air quality are key to maintaining healthy air quality, but are not enough on their own. For comprehensive air quality protection, utilizing both activated carbon and HEPA filters between various indoor spaces can help target direct sources of pollution, including:

For activated carbon air purifiers: Place in bathrooms, kitchens, and garages where chemical products and gaseous emissions are more abundant.
For HEPA and HyperHEPA air purifiers: Place in bedrooms, living rooms, and communal spaces where dust and bacteria can thrive.

Since they target different particles, it is key to utilize both activated carbon filters and HEPA or HyperHEPA filters in conjunction to eliminate all airborne pollutants present.

Frequently Asked Questions (FAQs)

How long do HEPA and HyperHEPA filters last?
HEPA and HyperHEPA filters can last 3 months to 4 years, depending on size, model, and daily usage.

How long do activated carbon filters last?
Activated carbon filters can last 6 months to 3 years, depending on size, model, and daily usage.

What is the difference between HyperHEPA and activated carbon filters?
The main difference between the two filters are the comprised materials and types of pollutant particles they remove.

HyperHEPA filters utilize densely packed fibers to remove airborne allergens and ultrafine particles such as dust, pollen, and smoke. Activated carbon filters utilize porous structures made of coconut shells or bituminous charcoal to filtrate gaseous odors and chemicals such as nitrogen oxide, benzene, and tobacco smoke and odor.

Does air purifier filter type matter?
Yes, air filter type does matter when dealing with different airborne pollutants. Some filter types are ineffective in removing certain particles, so it is important to select the right filter for the right job.

If a space has abundant pollen, dust, or mold, HEPA or HyperHEPA filters will be the best option to remove the particles. If a space is dealing with odor, chemical sprays, or gaseous emissions, activated carbon filters would be the best choice to eliminate the pollutants.

Conclusion

HEPA filtration and activated carbon filters target separate types of airborne pollutants, yet both are essential in providing comprehensively safe air quality. HEPA and HyperHEPA filters ensure airborne allergens and dust are filtrated, while activated carbon filters eliminate gaseous emissions and odors.

Without either HEPA filtration or activated carbon filters, gaps in air quality protection could arise, and hidden pollutants can continue to disrupt indoor air quality.

Household items are thrown away daily, contributing to overflowing landfills and 62 million tons of e-waste annually. Learn how to determine if technology is built for sustainability.

","Sustainability has become one of the defining promises of modern consumer technology. Companies highlight recycled materials, carbon-neutral operations, renewable energy, and environmentally friendly packaging. These initiatives matter, but they also raise a fundamental question: If a product is designed to be replaced after just a few years, can it truly be called sustainable? Too often, sustainability is measured by how products are made while overlooking what happens after they leave the factory. We celebrate manufacturing improvements yet accept an industry model that encourages consumers to replace perfectly functional devices long before they've reached the end of their useful life. I believe this is one of the biggest blind spots in sustainability today. The world generated a record 62 million metric tons of electronic waste in 2022, according to the United Nations [1]. That's enough to fill more than 1.5 million garbage trucks. Yet only about 22% of that waste was formally collected and recycled. Much of it wasn't discarded because products stopped working or became obsolete. It was discarded because they stopped being supported. Across consumer technology, software updates end, batteries become difficult to replace, repair options disappear, new models make older ones feel outdated, and older models intentionally work slower. Phone manufacturers, in particular, have normalized profit-driven product cycles that force replacement every three or five years, even when existing devices remain capable of meeting consumers' everyday needs. The result is what we call profit-driven waste: the unnecessary disposal of functional products because manufacturers and shareholders favors forced-replacement over longevity. The environmental cost extends far beyond landfills. Modern electronics depend on finite resources such as lithium, cobalt, nickel, copper, gold, and rare earth elements. Every unnecessary replacement drives additional mining, manufacturing, transportation, and disposal. Research from the European Environmental Bureau estimates that extending the average smartphone's lifespan by just one year across the European Union would reduce carbon emissions by approximately 2.1 million metric tons annually, roughly equivalent to removing nearly one million cars from the road [2]. That statistic points to an important truth: one of the most effective sustainability strategies isn't just producing more \"green\" products, it's also favoring longevity over forced replacement. At IQAir, this philosophy has fundamentally shaped how we approach product design. When we developed our Atem Earth and Atem Eco air purifiers, our goal wasn't simply to reduce the environmental impact of manufacturing. We wanted to reduce the environmental impact of ownership over decades. That meant asking different questions. How can we reduce plastic without compromising durability? How can we minimize energy consumption throughout a product's lifetime? How can we make products repairable instead of disposable? And perhaps most importantly, how can we build products customers won't need, or want, to replace after only a few years? The answers influenced every stage of development. Atem Earth uses 30% less plastic than conventional air purifiers through a more efficient design and sustainably sourced beech wood housing. Its frameless filter design reduces filter waste by up to 80%. The purifier operates using as little as 4 watts of electricity at low speed and only 50 watts at maximum performance, significantly reducing energy consumption over years of continuous operation. Perhaps most importantly, both Atem Earth and Atem Eco are designed with a 25-year repairability guarantee. Rather than assuming products will eventually become disposable, we engineered them to remain serviceable and operational for decades. To us, that is what sustainability looks like. This philosophy isn't limited to air purifiers. It represents an opportunity for the entire consumer technology industry. Imagine if more companies measured success not by how frequently customers upgraded, but by how long their products remained useful. Imagine if repairability became as important as processing power. Imagine if software support reflected the physical lifespan of the hardware instead of marketing cycles. Imagine if a product’s useful life became one of the industry's primary environmental goals. Consumers are already moving in this direction. Around the world, they're placing greater value on durability, repairability, and long-term reliability. Policymakers are responding with Right to Repair legislation and eco-design requirements that encourage longer product lifespans and easier maintenance. The future of sustainable technology won't be defined solely by recycled materials or carbon accounting. Those efforts matter, but they address only part of the equation. The next generation of sustainable products will be those designed to stay in homes longer, consume less energy over their lifetime, use fewer raw materials, remain repairable, and reduce the need for replacement altogether. In other words, sustainability should no longer be measured only by how products are made. It should be measured by how long they last. As an industry, we have become very good at greenwashing and talking about sustainability. The harder challenge is designing products that genuinely reduce consumption over decades instead of a handful of years. At IQAir, we believe that's the standard consumers should expect from every technology company. Because the greenest product isn't necessarily the newest one. It's the one that's still doing its job 25 years later.","

Find out how to get the most out of your air purifier by placing it where it’ll make the most difference.

","The best place to place an air purifier is where you spend the most time and where air circulation is unobstructed. For most people, this means placing the purifier in the bedroom (especially near the bed but not directly beside it), living room, or home office. Position the unit at least a few feet away from walls, furniture, or curtains to allow airflow in and out of the purifier. If your goal is to address specific concerns like allergies, pet dander, or outdoor pollution, place the purifier near the source of pollutants (e.g., near a pet’s favorite spot, windows, or entryways). Effective whole-home air purifiers are on the market, removing any placement concerns. Alternatively, consider using multiple purifiers in high-traffic areas or investing in a model with strong airflow capable of covering larger spaces (1). Why placement matters for air purification Where you place your air purifier directly impacts its effectiveness. Purifiers work by drawing in polluted air, filtering it, and releasing clean air back into the room. If the unit is tucked into a corner, blocked by furniture, or placed too close to a wall, airflow is restricted, reducing its ability to circulate and clean the air efficiently. Ideally, the purifier should be centered in the room or positioned where air can move freely around it. Avoid placing an air purifier behind curtains, under tables, or in closets, as these locations limit airflow and reduce performance. For certain rooms: In a bedroom: Place your air purifier 3–6 feet from the bed, away from direct drafts (like vents or open windows), to ensure clean air reaches your breathing zone while you sleep. In living areas: Position it near seating but not in a high-traffic pathway where it could be bumped or obstructed. For homes with multiple floors or large open spaces: Using one purifier per floor or zone can ensure even coverage. Special considerations for different rooms and needs If you live in an area with high outdoor pollution (e.g., near busy roads or wildfire-prone regions), place the purifier near windows or entryways—but close windows and doors during pollution spikes to prevent contaminants from entering. Certain rooms and spaces may require additional planning. Bedrooms Prioritize placement near the bed but avoid direct airflow onto your face while sleeping. A nightstand or dresser a few feet away is ideal for a desktop air purifier. Running the purifier on a quiet night mode ensures undisturbed sleep while maintaining air quality. Kitchens Position the purifier away from grease or steam (which can clog filters) but close enough to capture cooking odors and smoke. Avoid placing it directly above or beside the stove. Nurseries or children’s rooms Place the purifier out of reach but where it can circulate air effectively. Avoid placing it near cribs or play areas where cords or buttons could pose a hazard. Basements or garages These areas often have higher humidity or dust levels. Use a purifier with a pre-filter to handle larger particles and consider a dehumidifier if moisture is an issue. Offices or study spaces Position the air purifier near your workspace but not in a way that blows air directly onto papers or electronics, which could scatter dust. For help with placing and planning air purification for offices and schools, check out the Clean Air Facility Program and Clean Air Schools Program. Frequently Asked Questions Should I put my air purifier on the floor? Yes, you can place your air purifier on the floor. If you are placing a desktop air purifier, it’s better to elevate it on a table, nightstand, or shelf. Can I move my air purifier from room to room? Yes, but for best results, keep it in the room where you spend the most time (e.g., bedroom at night, living room during the day). How close should an air purifier be to my bed? Aim for 3–6 feet away from your bed, positioning desktop air purifiers so that clean air flows toward your breathing zone without blowing directly on you. Avoid placing it on the floor near the bed, where dust accumulation is higher. Do I need an air purifier in every room? Not necessarily. Start with the room where you spend the most time or where pollutants are most concentrated (e.g., bedrooms, living rooms). For whole-home coverage, consider a whole home air purification system or multiple units for larger homes. Can I place my air purifier near a window? You can. Close the window during high-pollution events (e.g., wildfires, smog, or allergy season) to prevent outdoor contaminants from entering. Otherwise, natural ventilation can complement the purifier’s work. Conclusion The best placement for your air purifier balances airflow, proximity to pollution sources, and accessibility. Position it in high-traffic areas where you spend the most time, elevate it slightly off the floor, and ensure it’s not obstructed by furniture or curtains. For targeted concerns like allergies or cooking fumes, place the purifier near the source but avoid direct exposure to steam, grease, or large debris. By strategically placing your air purifier and maintaining unobstructed airflow, you’ll maximize its ability to clean the air efficiently, reduce pollutants, and create a healthier indoor environment.

Why placement matters for air purification

Where you place your air purifier directly impacts its effectiveness.

Purifiers work by drawing in polluted air, filtering it, and releasing clean air back into the room. If the unit is tucked into a corner, blocked by furniture, or placed too close to a wall, airflow is restricted, reducing its ability to circulate and clean the air efficiently. Ideally, the purifier should be centered in the room or positioned where air can move freely around it.

Avoid placing an air purifier behind curtains, under tables, or in closets, as these locations limit airflow and reduce performance.

Allergens and ultrafine pollutants can invade indoor spaces, affecting respiratory health. Discover air cleaning research and clinically tested filtration for respiratory relief.

","Allergy season often brings elevated allergic reactions and asthmatic symptoms, limiting outdoor activities and open-air ventilation. Airborne allergens and pollutants can easily stick to clothing and sneak into indoor spaces undetected, impacting home air quality. The University of California, Davis in partnership with the California Air Resources Board (CARB) conducted the largest double-blind, placebo-controlled clinical trial to determine the most optimal air cleaning technology to properly eliminate allergen and pollutant particles. UC Davis and the CARB tested air purification tools against central filtration vents to measure each device’s particle reduction and asthmatic symptom improvement. Clean air testing environment Conducted by UC Davis researchers and funded by the CARB, the two-year study explored different filtration methods and their effects on pollutant particle removal within 172 various households in California (1). The study also measured air cleaning technology’s improvement of respiratory symptoms, surveying 191 asthmatic children ages 6-12. As a double-blind, placebo-controlled study, researchers aimed to minimize errors while producing comparative data. The study determined the filtration efficiency power and pollutant removal rates between personal single-room air purifiers and central filtration systems. Allergy and pollutant purification research UC Davis researchers examined the removal rates of air cleaning devices and central filtration systems on various airborne pollutants, including PM0.2, PM2.5, and PM10. PM0.2 is all particulate matter that is 0.2 microns in diameter or less, while PM2.5 includes particles 2.5 microns or less in size and PM10 is equivalent to 10 microns or less. During each household trial, either central air filtration or two stand-alone air purifiers were tested for pollutant removal rates compared to if there were no purification methods used. Table 1.

Out of the two high-efficiency devices tested, personal air purifiers removed the greatest percentage of ultrafine pollutants at 52%. Without proper treatment, airborne pollutants and ultrafine particles could elevate health risks through long-term exposure, such as asthmatic symptoms, respiratory complications, and irritable allergies. Optimal allergy filtration and asthma prevention High-efficiency, ultrafine particle control helps secure clean air quality and minimize airborne pollutants by utilizing air cleaning with advanced filters. HyperHEPA air purifiers are specifically designed to capture ultrafine pollutants, removing 99.5% of harmful particles up to 0.003 microns in size. HyperHEPA filters target common indoor pollutants that can cause allergic reactions or asthmatic flare-ups, such as: Pollen Pet dander Wildfire smoke Dust Bacteria Viruses PM2.5 PM10 For comprehensive air quality protection, multilayered filtration systems with Activated Carbon filters remove lingering odors, gaseous emissions, and volatile organic compounds. Air quality awareness is also just as important as the air cleaning technology itself. Indoor and outdoor air quality monitors can help plan daily schedules accordingly and determine when ventilation is safe. Clinical improvement through air cleaning technology According to UC Davis researchers, participants in the study reported about 20% less clinic visits and a slight reduction in healthcare utilization overall, especially for those with severe asthmatic conditions (2). A larger reduction of pollutants was observed when participants kept windows closed and ran air cleaning systems for the full duration of the study. Participants with air cleaning devices reported waking up fewer times during the night from asthmatic symptoms if bedroom doors were also closed (2). Extended air purifier runtimes combined with closed windows and doors can help air purifiers run more efficiently, providing effective filtration and maximized health protection. Conclusion High-efficiency filtration can remove airborne pollutants and ultrafine particles, providing relief for allergic reactions and asthmatic symptoms. Out of the two high-efficiency filtration devices tested, standalone air purifiers captured the greatest percentage of pollutants, eliminating even the smallest of particles with HyperHEPA technology. IQAir stand-alone air cleaners used in the study led to a 20% reduction in the sum of clinic visits, ER visits, and hospitalizations and a reduction in waking due to asthma when bedroom doors were kept closed. The most significant improvement was seen among severe asthmatics. Allergies and asthma can be difficult obstacles when going about your daily schedule, but with high-efficiency filtration, airborne pollutants can be easily captured and respiratory concerns swiftly alleviated.","

According to UC Davis researchers, participants in the study reported about 20% less clinic visits and a slight reduction in healthcare utilization overall, especially for those with severe asthmatic conditions (2). A larger reduction of pollutants was observed when participants kept windows closed and ran air cleaning systems for the full duration of the study.

Participants with air cleaning devices reported waking up fewer times during the night from asthmatic symptoms if bedroom doors were also closed (2). Extended air purifier runtimes combined with closed windows and doors can help air purifiers run more efficiently, providing effective filtration and maximized health protection.

Conclusion

High-efficiency filtration can remove airborne pollutants and ultrafine particles, providing relief for allergic reactions and asthmatic symptoms. Out of the two high-efficiency filtration devices tested, standalone air purifiers captured the greatest percentage of pollutants, eliminating even the smallest of particles with HyperHEPA technology.

IQAir stand-alone air cleaners used in the study led to a 20% reduction in the sum of clinic visits, ER visits, and hospitalizations and a reduction in waking due to asthma when bedroom doors were kept closed. The most significant improvement was seen among severe asthmatics.

Allergies and asthma can be difficult obstacles when going about your daily schedule, but with high-efficiency filtration, airborne pollutants can be easily captured and respiratory concerns swiftly alleviated.
