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. This treatment even has a clinical term: halotherapy, based on an ages-old respiratory treatment technique known as speleotherapy.

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. The app also tracks up to six key wildfire pollutants, such as PM2.5, CO2, and NO2, so that you have the best picture of your local air quality during a wildfire and can take action to help protect your health.

Environmental protections are weakening globally. See who pays the price and what comes next.

","Across some of the world's most developed democracies, the United States, the European Union, Australia, and New Zealand governments are rolling back the rules that were enacted to protect public health, stabilize economies, and preserve ecosystems. These are not isolated national stories. They are connected chapters in a global pattern, one in which industry lobbying, short-term economic pressure, and political expediency are chipping away at decades of environmental progress. And the consequences rarely stay within borders. Polluted air drifts across continents, weakened trade rules ripple through global supply chains, and the erosion of one country's protections can undercut the credibility of international agreements everywhere else. Where protections are rolling back In the United States, the Environmental Protection Agency has pursued what its own administrator called the \"single largest deregulatory action\" in the agency's history. In February 2026, the EPA finalized a rule eliminating the 2009 Endangerment Finding, the scientific determination that greenhouse gases threaten public health, effectively rescinding the legal foundation for federal emissions standards on cars, trucks, and power plants (1)(2). The agency has also granted coal-fired power plants exemptions from mercury and air toxics standards and repealed a 2024 rule that would have cut emissions of toxic air pollutants from petrochemical plants (3). The European Union has taken a subtler but no less consequential path. Since 2025, the European Commission has introduced ten \"omnibus\" packages, bundling changes that weaken corporate sustainability reporting, due diligence, and permitting requirements under the banner of \"simplification\" (4). Investigations by watchdog groups found that roughly 90% of meetings shaping these packages involved business interests, with heavy industry successfully pushing to delay the EU's carbon border tax, soften vehicle emissions rules, and fast-track permits for polluting infrastructure (5)(6). New Zealand, a nation long associated with strong conservation records, is also shifting course. New Zealand's coalition government has moved to weaken its National Policy Statement for Indigenous Biodiversity and freshwater protections, making it easier to approve mining and quarrying in ecologically sensitive areas (7). In Brazil, home to the majority of the Amazon rainforest, a new \"devastation bill\" took effect in February 2026, introducing a self-licensing system that lets developers sign off on their own environmental impact assessments for many projects (8). Each of these countries built its climate and conservation frameworks over generations. Undoing them, even partially, is proving to have cross-border consequences that fall hardest on the communities least equipped to withstand them. Weakened protections impact health Air pollution already contributes to more than 7 million premature deaths worldwide every year, according to the World Health Organization, making pollution the largest single environmental health risk on the planet (9). Weakened protections threaten to push that number higher, and the clearest evidence is emerging in the communities living closest to industrial pollution. In Louisiana's \"Cancer Alley,\" an 85-mile industrial corridor along the Mississippi River, researchers from Johns Hopkins University found in 2025 that cancer risks from airborne toxins were up to 11 times higher than official EPA estimates, largely because the agency's models rely on companies self-reporting their own emissions (10)(11). Just months earlier, the Trump administration had granted a dozen Louisiana petrochemical facilities two-year exemptions from a Biden-era rule designed to cut toxic emissions in these same communities (12). Life expectancy in parts of the Niger Delta, where decades of oil spills have contaminated environment, runs roughly a decade below Nigeria's national average, a pattern echoed in Cancer Alley, where residents already face elevated rates of respiratory illness, reproductive harm, and cancer (13). European cities are not immune. Warsaw, Poland, has made real progress, cutting fine particulate pollution by 46% since 2010 through coal-heating bans and clean transport zones (14). Yet the city still recorded \"unhealthy\" air quality spikes in early 2026, and eastern and southeastern Europe as a whole continue to bear the continent's heaviest burden of pollution-linked disease, with nearly all of the EU's urban population still exposed to fine particulate levels above WHO guidelines (15). Air pollution’s economic impact Governments rolling back environmental rules often frame the move as an economic win: fewer regulations, lower costs, more jobs. The reality is more complicated. A tracking project by the Institute for Policy Integrity estimates that just the rollbacks pursued by the current U.S. administration put more than $22 billion in annual health benefits at risk, benefits that would otherwise come from avoided hospital visits, missed workdays, and premature deaths (16). In Europe, a similar dynamic is unfolding. Corporate lobbying groups representing the automotive, chemical, and fossil fuel industries have spent tens of millions of euros pushing to delay the EU's carbon market reforms and weaken its carbon border tax, arguing that decarbonization rules threaten European competitiveness (17). Yet the same industries benefiting from looser rules are often the ones whose pollution imposes hidden costs on public health systems and the ecosystems their supply chains depend on. The palm oil industry illustrates the trade-off well. Despite over a decade of \"no deforestation\" pledges covering most of Indonesia and Malaysia's palm oil refining capacity, satellite monitoring found that more than 31,000 hectares of forest were still cleared for palm oil in Indonesia in 2025 alone, much of it entering supply chains that companies market as deforestation-free (18). Air pollution caused by land clearing for palm plantations impacts air quality in communities across the region each year, despite laws designed to cut emissions (19). The EU's own deforestation regulation, meant to close these loopholes, was delayed a year and then weakened further under industry pressure in late 2025 (20). Air pollution’s burden falls unevenly Weakened environmental protections rarely harm everyone equally. Time and again, it is marginalized communities who live closest to the pollution and farthest from the political power to stop it. In Europe, Roma communities across Hungary, Romania, Slovakia, Bulgaria, and North Macedonia continue to face what researchers call \"environmental racism,\" routinely relocated to or left in areas next to landfills, contaminated industrial sites, and mining waste, often without access to clean water or basic sanitation (21)(22). In one case in Kosovo, the United Nations found that a UN mission itself was responsible for relocating Roma families to a camp near a lead-contaminated industrial site, where residents suffered acute lead poisoning and miscarriages for years without compensation (23). Indigenous communities face similar patterns on a global scale. In Brazil, more than a third of the Amazon is designated Indigenous territory, and Indigenous-managed lands consistently show lower deforestation rates than surrounding areas (24). Yet Brazil's new self-licensing law and a legal doctrine limiting land claims to territory physically occupied as of 1988 threaten to strip protections from communities that were forcibly displaced decades earlier (25). In Nigeria's Niger Delta, Ogoni communities are still fighting for a promised cleanup of oil contamination that a 2011 UN assessment estimated could take up to 35 years, even as the Nigerian government pushes to resume drilling in the same region (26). In Canada and Australia, Indigenous groups similarly report being sidelined from decisions about mining, agriculture, and land development on or near traditional territories, often bearing the environmental costs of projects they had little say in approving. Ecosystems under mounting pressure The ecological toll of weakened protections is playing out across some of the planet's most iconic landscapes. In the Arctic, sea ice reached its lowest winter maximum extent in the 47-year satellite record in March 2025, a stark marker of a warming polar region even as summer melt patterns show some natural variability (27)(28). The long-term trend remains unambiguous: sea ice is thinner, younger, and less extensive than it was two decades ago, with cascading effects on global weather patterns and Indigenous communities whose ways of life are tied to the ice (29). New Zealand is confronting what one 2025 government report called a \"code red for nature.\" More than 4,000 native species are now threatened or at risk of extinction, including 76% of freshwater fish and 93% of frogs, driven largely by intensive dairy farming, habitat loss, and pollution of waterways (30)(31). Conservation groups warn that the government's recent move to weaken indigenous biodiversity and freshwater protections, making it easier to approve mining and quarrying, will accelerate a decline that is already among the worst in the world. What can be done The scale of these rollbacks can feel overwhelming, but the trend is not irreversible. Meaningful progress is still possible at every level. What governments can do Strengthen and enforce international environmental agreements rather than allowing them to be quietly weakened through delay and exemption. Invest in environmental monitoring systems that don't rely on industry self-reporting. Provide financial and technical support to developing nations working to build cleaner energy and industrial systems. Promote the transfer of green technology so that economic development and environmental protection are not treated as competing goals. What communities can do Build cross-border alliances with communities facing similar pollution and land-rights challenges. Support independent water and air quality monitoring organizations, particularly where government data relies on self-reporting from polluters. Educate community members about environmental risks and their legal rights to challenge harmful projects. Develop or support local air quality monitoring networks that can hold industry accountable with independent data. What individuals can do Reduce personal carbon footprint where possible, from waste, transportation choices to energy use. Support businesses and political leaders with genuine track records on environmental responsibility. Stay informed about local and national policy changes that affect environmental protections. The takeaway Weakening environmental protections is a human issue, which carries immediate consequences for human health and long-term consequences for ecosystem. When protections erode, the costs land hardest on communities with the least power to resist them. Reversing this trend will require sustained pressure from governments, communities, and individuals alike, at a moment when many of the institutions built to provide that pressure are themselves under strain. But the damage being done today can still be mitigated through dedicated, sustained activism in communities and nations around the world.","

Support businesses and political leaders with genuine track records on environmental responsibility.
Stay informed about local and national policy changes that affect environmental protections.

The takeaway

Weakening environmental protections is a human issue, which carries immediate consequences for human health and long-term consequences for ecosystem. When protections erode, the costs land hardest on communities with the least power to resist them.

Reversing this trend will require sustained pressure from governments, communities, and individuals alike, at a moment when many of the institutions built to provide that pressure are themselves under strain. But the damage being done today can still be mitigated through dedicated, sustained activism in communities and nations around the world.

Discover which pollutants specific filters are designed to remove from the air.

","From the outside, air purifiers may seem alike, but internally, filtration technology and power can be vastly different between every air system and filter. HEPA filtration is designed to eliminate particulate matter and airborne allergens, while activated carbon filters target gaseous pollutants. For comprehensive air quality protection, it is important to understand the differences between filter types, the various pollutants they target, and optimal locations for each filtration system. What are HEPA and HyperHEPA filters? To address particulate matter and airborne allergens, HEPA filtration systems are the way to go. HEPA filters are made of densely packed fibers that are 99.7% effective in capturing pollutants with a diameter of 0.3 microns or larger. PM2.5 is particulate matter measuring 2.5 microns or less and PM10 includes particles 10 microns or less. These particles can range from airborne allergens to indoor irritants. Within the HEPA filtration family, HyperHEPA air purifiers provide the maximum amount of protection against the smallest of pollutants. HyperHEPA filters specifically target ultrafine particles, eliminating 99.5% of airborne pollutants that are as small as 0.003 microns in size. Ultrafine particles and allergens can easily sneak indoors without one realizing through open doors, cracked windows, and clothing transfers. through open doors, cracked windows, and clothing transfers. What particles do HEPA filters remove? Through their dense fiber filtration design, HEPA and HyperHEPA filters specifically target fine particulate matter, ultrafine particles, and airborne allergens commonly found indoors, including: Dust Pet dander Pollen Wildfire smoke Mold Microorganisms Long-term exposure to these pollutant particles and allergens can increase health risks, such as nasal irritation, elevated allergies, lung cancer, and respiratory complications. HEPA and HyperHEPA filters are key to circulating and filtering indoor air pollutants, but they do not address all pollutants. What are activated carbon filters and how do they work? Activated carbon filters are designed to have biodegradable porous surfaces—commonly made of coconut shells, charcoal, or wood—that capture gas-phase pollutants. Carbon filters made from activated bituminous charcoal are the most effective in eliminating higher concentrations of pollutants (1). According to a study published in 2022, activated carbon filters were found to have captured and filtered 87.4% of NO2 particles within vehicles and areas of high pollutant concentration (2)(3). Through its porous structure, activated carbon filters target gases, vapors, odors, and volatile organic compounds (VOCs), including: Formaldehyde Benzene Nitrogen oxide Tobacco smoke and odor Cooking smoke and odor Chemical fumes Chemical and pollutant gas exposure can occur regularly indoors through cleaning products, paint, air fresheners, and carpets. Activated carbon filters are extremely effective in addressing airborne chemical exposure, but the air system has limitations and does not capture particulate matter. How do activated carbon filters compare to HEPA filtration? Activated carbon filters target different forms of airborne pollutants compared to HEPA and HyperHEPA filters. Activated carbon filters are made up of tiny holes that specifically designed to capture chemicals, gases, and odors—pollutants often invisible to the naked eye. 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.","

From the outside, air purifiers may seem alike, but internally, filtration technology and power can be vastly different between every air system and filter. HEPA filtration is designed to eliminate particulate matter and airborne allergens, while activated carbon filters target gaseous pollutants.

For comprehensive air quality protection, it is important to understand the differences between filter types, the various pollutants they target, and optimal locations for each filtration system.

What are HEPA and HyperHEPA filters?

To address particulate matter and airborne allergens, HEPA filtration systems are the way to go. HEPA filters are made of densely packed fibers that are 99.7% effective in capturing pollutants with a diameter of 0.3 microns or larger. PM2.5 is particulate matter measuring 2.5 microns or less and PM10 includes particles 10 microns or less. These particles can range from airborne allergens to indoor irritants.

Within the HEPA filtration family, HyperHEPA air purifiers provide the maximum amount of protection against the smallest of pollutants. HyperHEPA filters specifically target ultrafine particles, eliminating 99.5% of airborne pollutants that are as small as 0.003 microns in size. Ultrafine particles and allergens can easily sneak indoors without one realizing through open doors, cracked windows, and clothing transfers. through open doors, cracked windows, and clothing transfers.

With summer in full swing, air quality is becoming an increasing concern for outdoor community events. Learn the importance of planning ahead to protect yourself and fellow attendees.

","As North America hosts some of the largest sporting events, concerts, festivals, races, and outdoor gatherings in its history, organizers are spending significant time planning for weather, security, transportation, and crowd safety. One critical factor often receives far less attention: air quality. A recent study published in Science found that increasing wildfire emissions are reversing decades of progress in reducing ozone pollution across the United States. Researchers found that ozone concentrations declined between 2003 and 2015, but many of those gains were lost between 2015 and 2024 as wildfire activity increased. The findings suggest that air quality conditions may become increasingly variable during the same seasons when many outdoor events take place. The study adds to a growing body of evidence showing that air quality is becoming more difficult to predict and more important to monitor. For organizations responsible for outdoor events, that trend carries practical implications. Millions of people spend time outdoors participating in events every year. At the same time, wildfire smoke has become a recurring challenge across large parts of North America. Communities located far from active fires are increasingly experiencing elevated levels of particulate pollution and ozone. Air quality is becoming another operational variable that event organizers need to manage. The Air Quality Blind Spot Most organizations already have established protocols for weather. Lightning can delay a game. Extreme heat can trigger cooling measures. Severe storms can postpone or cancel an event altogether. These systems exist because organizers understand that environmental conditions directly impact safety. Air quality often remains the exception. Many organizations still lack clear thresholds for action, communication protocols, or contingency plans when pollution levels become unhealthy. Yet air pollution can affect respiratory function, cardiovascular health, athletic performance, and overall well-being. Sensitive populations, including children, older adults, and people with asthma or other respiratory conditions, may face elevated risks during pollution events. Unlike severe weather, poor air quality is not always obvious. Ozone is invisible, and high PM2.5 levels may not be immediately apparent. Without monitoring, organizers may not know conditions have changed until participants begin reporting symptoms. From an Environmental Issue to an Operational Issue For years, air quality was viewed primarily as an environmental concern. Increasingly, it is becoming an operational concern, as well. Organizations cannot effectively manage risks they cannot see. As environmental conditions become less predictable, access to reliable air quality information becomes an important part of planning, communication, and public safety decision-making. Just as organizations have learned to adapt to extreme heat and severe weather, they can incorporate air quality into broader risk management strategies. That starts with access to reliable, real-time information. Event organizers should understand local air quality conditions before an event begins and have systems in place to monitor changing conditions throughout the day. It also requires clear decision-making frameworks. What air quality thresholds trigger public health advisories? How will participants and spectators be notified? What accommodations are available for sensitive individuals? How will organizers respond if conditions deteriorate unexpectedly? These are questions that can be addressed before an event begins rather than during a crisis. A New Era of Event Planning The Science study reflects a broader shift in the way event organizers need to think about air quality. Wildfires and extreme heat are affecting more communities, while many major metropolitan areas already contend with pollution from traffic, energy production, and other urban sources.

The Air Quality Blind Spot

Most organizations already have established protocols for weather. Lightning can delay a game. Extreme heat can trigger cooling measures. Severe storms can postpone or cancel an event altogether. These systems exist because organizers understand that environmental conditions directly impact safety.

Air quality often remains the exception.

Many organizations still lack clear thresholds for action, communication protocols, or contingency plans when pollution levels become unhealthy.

Air quality is becoming an increasing issue globally, but local communities are fighting back against pollution. See how these 5 Asian cities have taken steps to improve their air quality.

","The 2025 World Air Quality Report indicates signs of progress despite the ongoing global struggle with air pollution. Some of Asia’s biggest cities reduced their PM2.5 concentrations in 2025 when compared to 2024. However, those improvements are still far from sufficient. Three of the five cities on this list continue to consistently experience air quality levels classified as very unhealthy to hazardous. Millions of residents in these major cities still face elevated health risks from long-term exposure to airborne pollutants like PM2.5 – tiny particulate matter measuring less than 2.5 microns in diameter. Vulnerable populations, such as children, the elderly, and those with pre-existing conditions like asthma or heart disease, bear the brunt of this burden. Though there is much more progress to be made, any improvement in air quality is a step in the right direction towards achieving safe and breathable air for all. 5. Ulaanbaatar, Mongolia Ulaanbaatar reduced its average annual PM2.5 concentration from 25.7 µg/m³ in 2024 to 17.9 µg/m³ in 2025, an improvement of 7.8 µg/m³. The decreased PM2.5 levels is a step in the right direction towards healthy breathing, but Ulaanbaatar’s air quality still does not reach the World Health Organization’s safe concentration level guideline of 5 µg/m³ (1). Diesel fuels and coal burning are common resources for resident heating and vehicle operations in Ulaanbaatar, creating an abundance of airborne pollutants. Especially in the colder winter months, added coal burning and temperature inversions trap large amounts of pollutants close to the ground, elevating PM2.5 concentrations. Air quality in Ulaanbaatar, Mongolia on June 25, 2026. Source: IQAir. In 2019, the Mongolian Government enacted a ban against raw coal utilization for domestic heating (2). Long-term clean air solutions depend on resources that provide sustainable fuel and healthy utilization with low respiratory risks. 4. Chiang Mai, Thailand Chiang Mai saw its average annual PM2.5 concentration drop from 26.4 µg/m³ in 2024 to 18.2 µg/m³ in 2025, marking an 8.2 µg/m³ improvement. The shift in PM2.5 levels is a notable improvement for the northern Thai city, inching closer to safe air quality levels for all. However, Chiang Mai maintains a moderate air quality index, which may depend on clean fuel and agricultural resources to reach low-risk PM2.5 concentrations. Air quality in Chiang Mai, Thailand on June 25, 2026. Source: IQAir. Chiang Mai experiences fluctuating air quality conditions and seasonal pollutants bursts, particularly during the dry season. Cultural crop burnings are the most prevalent in Chiang Mai, causing mass production of volatile organic compounds (VOCs) and particulate matter across the city within the warmer months. Communities and residents in Thailand have pushed for systemic change within the air quality landscape, introducing a Clean Air Bill and non-profit initiatives (3). 3. Delhi, India Delhi, one of the world’s most polluted cities, was able to lower its average annual PM2.5 concentration from 108.3 µg/m³ in 2024 to 99.6 µg/m³ in 2025, an improvement of 8.7 µg/m³. While the reduced PM2.5 levels are an impactful step towards safe breathing conditions, Delhi’s air quality index remains in the unhealthy range, and airborne pollutants could still invade indoor spaces. Air quality in Delhi, India on June 25, 2026. Source: IQAir. Delhi, a populous urban city, experiences a complex mix of airborne pollutants and harmful particulate matter year-round, including construction dust, cultural crop burnings, and industrial emissions. Traffic pollution and gases are among the most prevalent pollutants in India, contributing to about 11% of air pollutant-related deaths in the country (4). In 2026, Delhi reformed traffic policies and promoted incentives for residents to switch to electric-powered vehicles (5)(6). However, long-term systemic shifts in fuel utilization and energy sources hold the potential to extend air quality improvements. 2. Dhaka, Bangladesh Dhaka reduced its average annual PM2.5 concentration from 78 µg/m³ in 2024 to 68 µg/m³ in 2025, achieving a 10 µg/m³ improvement. Dhaka has maintained unhealthy AQI levels since the first World Air Quality Report in 2017, but the city has reached its most improved PM2.5 concentrations in 2025. Despite the improved air quality conditions and decreased PM2.5 exposure, the city’s air remains at an unhealthy AQI level, creating a harmful breathing environment for sensitive populations. Dhaka faces numerous air pollution concerns derived from busy highways and high-production factories, including abundant traffic emissions, particulate matter from construction sites, and industrial smoke. As a country, Bangladesh established a National Air Quality Management Plan for 2024-2030, focused on reducing PM2.5 concentrations and decreasing pollutant production nationwide. For long-term air quality improvement, limiting brick kilns and harmful cooking sources is key, as these pollutants have been linked to elevated respiratory health risks and the production of over 200 volatile organic compounds (7). Air quality in Dhaka, Bangladesh on June 25, 2026. Source: IQAir. 1. Lahore, Pakistan Lahore achieved the most significant improvement among the top five major cities. The city reduced its average annual PM2.5 concentration from 102.1 µg/m³ in 2024 to 88.9 µg/m³ in 2025, a 13.2 µg/m³ drop. Air quality in Lahore, Pakistan on June 25, 2026. Source: IQAir. While a positive development, this progress needs to be weighed in context with another fact: Lahore’s air quality has been in the hazardous range since the first World Air Quality Report in 2017, and it was ranked the second most polluted major city in the world in 2025. The city’s pollution is driven by a combination of factors, including vehicular emissions from an aging fleet, industrial activity, dust from construction, and seasonal crop burning in Punjab Province. While the Pakistani government has introduced measures such as smog alerts, temporary school closures, and restrictions on certain industrial activities during high-pollution periods, seasonal air quality issues persist. The health impact is clear: 68% of Pakistanis reported smog-related health issues in a survey conducted in 2024. 84% of respondents living in Lahore noted they had experienced respiratory illnesses (8). Pathways to cleaner air While the improvements in these cities are a step in the right direction, mitigating persistent poor air quality requires sustained action. Here’s how progress can be accelerated: What governments can do Strengthen and enforce air quality standards to hold industries and vehicles accountable for their emissions. Invest in renewable energy and public transportation to reduce reliance on fossil fuels and private vehicles. Expand air quality monitoring networks to provide real-time data and inform targeted interventions. Promote regional cooperation to address transboundary pollution, such as crop burning and industrial emissions that cross borders. What communities can do Support and participate in local initiatives to raise awareness about air pollution and its health impacts. Advocate for stronger policies and better enforcement to protect vulnerable populations. What individuals can do Choose sustainable transportation options, such as walking, cycling, or using public transit, to reduce personal contributions to air pollution. Use air purifiers and wear high-quality masks on high-pollution days to limit exposure. Stay informed about real-time air quality data to make healthier daily decisions. Conclusion Air quality improvement in these five Asian cities offers hope in the ongoing fight for clean air. However, the fact that three of these cities—Delhi, Dhaka, and Lahore—still have air quality levels classified as unhealthy to hazardous underscores the long journey towards clean air quality. It’s true that millions of people in these cities and around the world continue to breathe air that is far from safe. Yet progress shown in 2025 can serve as a foundation for bolder, more ambitious action to ensure that clean air becomes a reality for all.","

Some of Asia’s biggest cities reduced their PM2.5 concentrations in 2025 when compared to 2024. However, those improvements are still far from sufficient. Three of the five cities on this list continue to consistently experience air quality levels classified as very unhealthy to hazardous.

Millions of residents in these major cities still face elevated health risks from long-term exposure to airborne pollutants like PM2.5 – tiny particulate matter measuring less than 2.5 microns in diameter. Vulnerable populations, such as children, the elderly, and those with pre-existing conditions like asthma or heart disease, bear the brunt of this burden. Though there is much more progress to be made, any improvement in air quality is a step in the right direction towards achieving safe and breathable air for all.

5. Ulaanbaatar, Mongolia

$\"\"$

Ulaanbaatar reduced its average annual PM2.5 concentration from 25.7 µg/m³ in 2024 to 17.9 µg/m³ in 2025, an improvement of 7.8 µg/m³.

The decreased PM2.5 levels is a step in the right direction towards healthy breathing, but Ulaanbaatar’s air quality still does not reach the World Health Organization’s safe concentration level guideline of 5 µg/m³ (1).

Diesel fuels and coal burning are common resources for resident heating and vehicle operations in Ulaanbaatar, creating an abundance of airborne pollutants. Especially in the colder winter months, added coal burning and temperature inversions trap large amounts of pollutants close to the ground, elevating PM2.5 concentrations.

In 2019, the Mongolian Government enacted a ban against raw coal utilization for domestic heating (2). Long-term clean air solutions depend on resources that provide sustainable fuel and healthy utilization with low respiratory risks.

4. Chiang Mai, Thailand

$\"\"$

Chiang Mai saw its average annual PM2.5 concentration drop from 26.4 µg/m³ in 2024 to 18.2 µg/m³ in 2025, marking an 8.2 µg/m³ improvement.

The shift in PM2.5 levels is a notable improvement for the northern Thai city, inching closer to safe air quality levels for all. However, Chiang Mai maintains a moderate air quality index, which may depend on clean fuel and agricultural resources to reach low-risk PM2.5 concentrations.

Chiang Mai experiences fluctuating air quality conditions and seasonal pollutants bursts, particularly during the dry season. Cultural crop burnings are the most prevalent in Chiang Mai, causing mass production of volatile organic compounds (VOCs) and particulate matter across the city within the warmer months.

Communities and residents in Thailand have pushed for systemic change within the air quality landscape, introducing a Clean Air Bill and non-profit initiatives (3).

3. Delhi, India

$\"\"$

Delhi, one of the world’s most polluted cities, was able to lower its average annual PM2.5 concentration from 108.3 µg/m³ in 2024 to 99.6 µg/m³ in 2025, an improvement of 8.7 µg/m³.

While the reduced PM2.5 levels are an impactful step towards safe breathing conditions, Delhi’s air quality index remains in the unhealthy range, and airborne pollutants could still invade indoor spaces.

$\"\"$

Delhi, a populous urban city, experiences a complex mix of airborne pollutants and harmful particulate matter year-round, including construction dust, cultural crop burnings, and industrial emissions. Traffic pollution and gases are among the most prevalent pollutants in India, contributing to about 11% of air pollutant-related deaths in the country (4).

In 2026, Delhi reformed traffic policies and promoted incentives for residents to switch to electric-powered vehicles (5)(6). However, long-term systemic shifts in fuel utilization and energy sources hold the potential to extend air quality improvements.

2. Dhaka, Bangladesh

$\"\"$

Dhaka reduced its average annual PM2.5 concentration from 78 µg/m³ in 2024 to 68 µg/m³ in 2025, achieving a 10 µg/m³ improvement.

Dhaka has maintained unhealthy AQI levels since the first World Air Quality Report in 2017, but the city has reached its most improved PM2.5 concentrations in 2025. Despite the improved air quality conditions and decreased PM2.5 exposure, the city’s air remains at an unhealthy AQI level, creating a harmful breathing environment for sensitive populations.

Dhaka faces numerous air pollution concerns derived from busy highways and high-production factories, including abundant traffic emissions, particulate matter from construction sites, and industrial smoke. As a country, Bangladesh established a National Air Quality Management Plan for 2024-2030, focused on reducing PM2.5 concentrations and decreasing pollutant production nationwide. For long-term air quality improvement, limiting brick kilns and harmful cooking sources is key, as these pollutants have been linked to elevated respiratory health risks and the production of over 200 volatile organic compounds (7).

1. Lahore, Pakistan

$\"\"$

Lahore achieved the most significant improvement among the top five major cities. The city reduced its average annual PM2.5 concentration from 102.1 µg/m³ in 2024 to 88.9 µg/m³ in 2025, a 13.2 µg/m³ drop.

$\"\"$

While a positive development, this progress needs to be weighed in context with another fact: Lahore’s air quality has been in the hazardous range since the first World Air Quality Report in 2017, and it was ranked the second most polluted major city in the world in 2025.

The city’s pollution is driven by a combination of factors, including vehicular emissions from an aging fleet, industrial activity, dust from construction, and seasonal crop burning in Punjab Province. While the Pakistani government has introduced measures such as smog alerts, temporary school closures, and restrictions on certain industrial activities during high-pollution periods, seasonal air quality issues persist. The health impact is clear: 68% of Pakistanis reported smog-related health issues in a survey conducted in 2024. 84% of respondents living in Lahore noted they had experienced respiratory illnesses (8).

Pathways to cleaner air

While the improvements in these cities are a step in the right direction, mitigating persistent poor air quality requires sustained action. Here’s how progress can be accelerated:

What governments can do

Strengthen and enforce air quality standards to hold industries and vehicles accountable for their emissions.
Invest in renewable energy and public transportation to reduce reliance on fossil fuels and private vehicles.
Expand air quality monitoring networks to provide real-time data and inform targeted interventions.
Promote regional cooperation to address transboundary pollution, such as crop burning and industrial emissions that cross borders.

What communities can do

Support and participate in local initiatives to raise awareness about air pollution and its health impacts.
\nAdvocate for stronger policies and better enforcement to protect vulnerable populations.

What individuals can do

Choose sustainable transportation options, such as walking, cycling, or using public transit, to reduce personal contributions to air pollution.
\nUse air purifiers and wear high-quality masks on high-pollution days to limit exposure.
Stay informed about real-time air quality data to make healthier daily decisions.
\n

Conclusion

Air quality improvement in these five Asian cities offers hope in the ongoing fight for clean air. However, the fact that three of these cities—Delhi, Dhaka, and Lahore—still have air quality levels classified as unhealthy to hazardous underscores the long journey towards clean air quality.

It’s true that millions of people in these cities and around the world continue to breathe air that is far from safe. Yet progress shown in 2025 can serve as a foundation for bolder, more ambitious action to ensure that clean air becomes a reality for all.

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. Air purifiers with True HEPA filtration capture various airborne particles such as PM2.5, PM10, and some volatile organic compounds (VOCs). PM2.5 is particulate matter measuring up to 2.5 microns and PM10 includes particles up to 10 microns in size. True HEPA filters also target various indoor pollutants and irritants, such as: Pollen Pet Dander Dust Fibers Allergens True HEPA filtration and standard HEPA filters remove the same types of pollutant particles at the same efficiency rate of 99.97% (1). Although the HEPA filter system family has powerful efficiency rates, some air purifier filters could be mislabeled or appear as standardized HEPA when they are not. What are HEPA-type filters? HEPA-type filters are comprised of the same structure and appearance as HEPA filters, but do not have the same efficiency, industry qualifications, or certifications as standard HEPA filters. Without standardized testing, these filters could have similar efficiency values as HEPA filters or be vastly different and have very low filtration power. HEPA-type filters could be suitable for low dust maintenance; however, with no standard removal rate or particle targeting technology, the collection of specific pollutant types can vary. When selecting an air purifier, looking for HEPA filter certifications, high-efficiency removal rates, and accommodations for small particle size is key to securing maximum filtration power and certified HEPA technology.

Humidifiers run on a tank of water that should be routinely checked and swapped out daily to avoid mold growth and build-up.

What is better, an air purifier or a humidifier?
Each air quality system performs their own unique tasks and is equally important in providing comprehensively safe and comfortable indoor air.

However, humidifiers may have more limitations on utilization schedule, as outdoor weather could impact humidifier usage and elevate mold risks.

Should I get an air purifier or humidifier for flu prevention?
To protect against the flu, air purifiers provide the most optimal support by filtering and removing bacteria and airborne viruses. Humidifiers may help with flu symptoms such as dry throat and nasal irritation; however, they do not actively remove or filtrate virus particles like air purifiers do.

Conclusion

Air purifiers focus on removing and filtering out airborne pollutants and viruses, while humidifiers add moisture into the air by expelling water vapor particles. Both devices are important air quality improvement tools with significant health benefits when used together, but only within the right environmental conditions.

For a comprehensively safe and comfortable indoor air quality, employ both air purifiers and humidifiers to address individualized room needs.
