In 2020, a study linked COVID-19 and air pollution when rising concentrations of PM2.5 in a single day correlated with increases in COVID-19 cases reported for the following two weeks (3). Air filtration can help capture PM2.5 and airborne infectious viruses, an important part of an overall strategy for returning to work after COVID-19. Clean air is essential to maintaining a healthy indoor environment for both human health and work productivity. A 2019 study published in the American Economic Journal: Applied Economics found that textile workers in factories exposed to consistently high pollution levels produced significantly less work output after 30 days (4). An additional 2019 study in the same publication found that productivity dropped among workers in two call centers during days when their cities experienced higher levels of air pollution (5). In 2020, a systematic review inCurrent Opinion on Psychology of 178 published articles on psychological, economic, and social effects of air pollution noted that decreased worker productivity was a recurring finding among the numerous negative impacts listed such as increased self-harm and cognitive impairment (6). Indoor concentrations of some pollutants can be between two and five times higher than typical outdoor concentrations (7). In addition to indoor sources of air pollution like combustibles, cleaning supplies, and building material off-gassing, outdoor air pollutants can seep in through cracks, ventilation, doors, and windows and become trapped. Indoor concentrations of some pollutants can be between two and five times higher than typical outdoor concentrations.

If a facility is trying to meet sustainability goals by reducing overall environmental impacts and achieve exceptional facility air quality standards, a clean air plan with excellent air filtration provides several benefits. Quality air filtration reduces particle pollution, one of the greatest pollutant threats to human health. Breathing in airborne particles like PM2.5 or even more coarse PM10 can result in cardiovascular and respiratory illness (8). Even smaller particle pollutants, ultrafine particles, are so small that they can cause systemic damage to the human body by penetrating deep into the lung tissue and bodily organs (9).

IWBI WELL Building Standards

The IWBI launched the WELL Building Standard (TM) as a set of criteria for awarding building environmental, health, and wellness certification.

The International WELL Building Institute aligns with IQAir’s mission, establishing rigorous performance standards to create and certify spaces that advance human health and well-being.

The WELL Building Standard (TM) takes into consideration an array of environmental health factors impacted by building design, construction, and facilities management. WELL standards are:

evidence-based
verified as factual through a third party
tested and implemented in real-world settings
open to outside input from practitioners, subject matter experts, users, and other third parties

Buildings that meet WELL standards for certification must adhere to a rigorous set of specifications for occupant safety within ten key concept areas, including:

air quality
water quality
nourishment and nutritional transparency
lighting environments
movement and physical activity
thermal comfort
sound and acoustical comfort
chemical and building materials
cognitive and emotional well-being
community
innovation – strategies to improve environmental health not included in the other concepts

The WELL Air concept sets building standards for maintaining high levels of indoor air quality throughout a building (1). Some of the main features of the Air concept:

meeting specific indoor air quality thresholds for:\n
- particulate matter (PM2.5)
- \norganic and inorganic gases
- radon
- air quality monitoring
\n
reducing indoor and outdoor airborne pollutants through air filtration
smoke-free environment, both indoor and outdoor
adequate ventilation design
mitigating construction pollution
minimizing combustion

Because no amount of PM2.5 is safe, it is important to install high quality air filtration and monitor air quality.

Unborn and newborn babies face grave risks from high levels of exposure to dirty air, including underdeveloped organs, premature births, low birthweight, and even infant mortality (1).Threats to the developing brainThe most dangerous pollutants in the air are ultrafine particles (UFPs), those that are smaller than 0.1 microns and constitute about 90% all airborne pollutants. They pose the potential for great harm to a baby’s brain development because they can easily penetrate the blood-brain-barrier.Infants are especially vulnerable to air pollution because (2) (3): their lungs are still developing they have faster breathing rates than adults, so they absorb more pollutants they spend time close to the ground where certain pollutants concentrate they are very active But air pollution begins doing its damage even prior to birth.Prenatal Exposure to air pollutionStudies have shown that damage to a baby’s brain development from air pollution can begin in the womb. One Netherlands-based analysis linked greater exposure to air pollution during pregnancy to underdeveloped areas of the brain, including the nucleus accumbens, which helps guide motivational and emotional processes (4) (5).Researchers at the University of Washington showed that pregnant women who were exposed to higher level of nitrous dioxide (NO2) were more likely to give birth to babies that develop behavioral problems.A 2022 study led by researchers at the University of Washington showed that expectant mothers who were exposed to higher levels of nitrous dioxide (NO2) were more likely to give birth to babies that develop behavioral problems (6).Another study, this one published in 2015, found a similar correlation between prenatal exposure to air pollution and behavioral issues in children. (7).Higher the level of exposure in the womb to polycyclic aromatic hydrocarbons (PAHs - a group of chemicals that are the byproducts of burning coal, gasoline, trash, and other sources) the less white matter (nerve fibers that connect different brain regions) there was in the left hemisphere of a baby’s brain.Lower amounts of white matter in that region are linked to behavioral problems.When exposed in the womb to high levels of PAHs, children are more likely to suffer from a variety of mental health issues, including depression, attention difficulties and increased stress.A study at New York City’s Columbia University found that when exposed in the womb to high levels of PAHs, children are more likely to suffer from a variety of mental health issues, including depression, attention difficulties and increased stress, which has been identified as a precursor to other, more serious psychiatric disorders (8) (9).A link to cognitive decline in childrenIn addition to the neurological disorders already discussed, numerous studies have revealed air pollution’s alarming impact on children’s cognition.The children that had high levels of exposure to air pollution in the Netherlands study were also found to have underdeveloped hippocampi, which play a key function in learning and memory (10).Scientists discovered decreased white matter in the prefrontal cortex, the area of the brain tied to concentration, reasoning, judgment, and problem-solving ability.In the 2015 study on the exposure of expectant mothers to PAHs, the brains of the babies were scanned again at age 5.

Expectant mothers all wish for the same thing – healthy babies.

Unfortunately, air pollution is a hidden danger that can prevent those wishes from coming true. Unborn and newborn babies face grave risks from high levels of exposure to dirty air, including underdeveloped organs, premature births, low birthweight, and even infant mortality (1).

Threats to the developing brain

The most dangerous pollutants in the air are ultrafine particles (UFPs), those that are smaller than 0.1 microns and constitute about 90% all airborne pollutants. They pose the potential for great harm to a baby’s brain development because they can easily penetrate the blood-brain-barrier.

Infants are especially vulnerable to air pollution because (2) (3):

their lungs are still developing
they have faster breathing rates than adults, so they absorb more pollutants
they spend time close to the ground where certain pollutants concentrate
they are very active

But air pollution begins doing its damage even prior to birth.

Prenatal Exposure to air pollution

Studies have shown that damage to a baby’s brain development from air pollution can begin in the womb.
\n\nOne Netherlands-based analysis linked greater exposure to air pollution during pregnancy to underdeveloped areas of the brain, including the nucleus accumbens, which helps guide motivational and emotional processes (4) (5).

Researchers at the University of Washington showed that pregnant women who were exposed to higher level of nitrous dioxide (NO2) were more likely to give birth to babies that develop behavioral problems.

A 2022 study led by researchers at the University of Washington showed that expectant mothers who were exposed to higher levels of nitrous dioxide (NO2) were more likely to give birth to babies that develop behavioral problems (6).

Another study, this one published in 2015, found a similar correlation between prenatal exposure to air pollution and behavioral issues in children. (7).

Higher the level of exposure in the womb to polycyclic aromatic hydrocarbons (PAHs - a group of chemicals that are the byproducts of burning coal, gasoline, trash, and other sources) the less white matter (nerve fibers that connect different brain regions) there was in the left hemisphere of a baby’s brain.

Lower amounts of white matter in that region are linked to behavioral problems.

When exposed in the womb to high levels of PAHs, children are more likely to suffer from a variety of mental health issues, including depression, attention difficulties and increased stress.

A study at New York City’s Columbia University found that when exposed in the womb to high levels of PAHs, children are more likely to suffer from a variety of mental health issues, including depression, attention difficulties and increased stress, which has been identified as a precursor to other, more serious psychiatric disorders (8) (9).

A link to cognitive decline in children

In addition to the neurological disorders already discussed, numerous studies have revealed air pollution’s alarming impact on children’s cognition.

The children that had high levels of exposure to air pollution in the Netherlands study were also found to have underdeveloped hippocampi, which play a key function in learning and memory (10).

Scientists discovered decreased white matter in the prefrontal cortex, the area of the brain tied to concentration, reasoning, judgment, and problem-solving ability.

In the 2015 study on the exposure of expectant mothers to PAHs, the brains of the babies were scanned again at age 5. This time the scientists discovered decreased white matter in the prefrontal cortex, the area of the brain tied to concentration, reasoning, judgment, and problem-solving.

The University of Washington study found that children two to four years of age who were exposed to higher levels of PM2.5 (pollution particles that are 2.5 microns in diameter or smaller) than their peers had lower cognitive performances.

Decreasing the risks of stunted brain development

No matter where you live, there are steps you can take to lessen a baby’s exposure to harmful airborne particles, helping to ensure the baby’s brain development is not impeded.

Limit or eliminate indoor sources of pollutants. Be vigilant of outdoor air pollution seeping inside especially during morning and evening rush hours. Low-cost indoor air quality monitors are available to help you track the air quality inside your residence.

Monitor your local outdoor air quality and when pollution particle levels are high, close windows and doors and restrict outdoor activities.

Use a high-performance air purifier. This is particularly significant in a child’s nursery.

One of the most important steps you can take is to use a high-performance air purifier. This is particularly critical in a baby’s nursery. There are compact personal air purifiers available that direct clean air right to a baby’s breathing zone.

The takeaway

Exposure to poor air quality affects our brain functions from the womb and all the way into old age.

The findings of a recent study hammered that point home when it showed a strong link between childhood air pollution exposure and the early development of Alzheimer’s disease symptoms (11).

The research reviewed the autopsies of children in Mexico City, one of the world’s most polluted metropolitan areas.

Compared with control subjects from areas with better air quality, the young people that had been living in Mexico City displayed numerous signs indicating accelerated progression of Alzheimer’s disease including an imbalance in certain genes, neurovascular damage, neuroinflammation, and brain lesions.

The researchers concluded that more attention must be paid to the devastating effects that air pollution creates on the brain development of babies and young people.

The study’s authors called for the prioritization of air pollution policies and regulations, and the targeting of neuroprotective interventions in the early years in a person’s life, especially those who are exposed to high levels of pollutants in the air they breathe.

Air pollution can be controlled. So can the devastating impacts air pollution has on brain development.

Here’s how to tell the difference between COVID-19 fact and fiction.","It’s impossible to read about the COVID-19 coronavirus (a serious, often fatal respiratory disease) without running into a few dangerous myths. But some of these myths can be deadly. So let’s explore three COVID-19 myths to learn about the most widely spread rumors. Myth: Asymptomatic people can’t spread the coronavirus The idea of the “silent spread” of SARS-CoV-2 – that asymptomatic people can spread the coronavirus – has spread like wildfire. After some confusion, the World Health Organization (WHO) clarified that most documented cases of “asymptomatic” spread actually turned out to be cases in which the person was presymptomatic and later developed mild or severe symptoms. Therefore, the WHO acknowledged that asymptomatic people can play a role in spreading tSARS-CoV-2 (which stands for severe acute respiratory syndrome coronavirus 2) responsible for COVID-19.1 It’s also important to acknowledge that the term “asymptomatic” as used in everyday conversations can actually have three different scientific meanings: When you’re asymptomatic, you are carrying the virus but show no symptoms. However, you are still able to infect others. When you’re presymptomatic, you have recently contracted the virus and have yet to show symptoms and are also asymptomatic. You are still able to infect others at this stage of infection and will begin to show mild or severe symptoms. When you are mildly symptomatic, you do not experience pneumonia associated with COVID-19, but rather mild coronavirus symptoms. You belong to the most infectious types of spreaders, as it is highly likely that you’re out and about. And several extensive studies suggest that cases of asymptomatic people that test positive for the presence of SARS-CoV-2 in their bodies often turn out to be presymptomatic.2,3,4 However, all of these “asymptomatic” types of spreaders should be taken seriously. According to the WHO, there are three primary ways that you can catch COVID-19: being coughed or sneezed on by someone with an active infection and symptoms5 touching a surface that carries infected respiratory droplets and then touching your face (eyes, nose, or mouth)6,7 being in enclosed spaces where infected airborne particles can build up You can transmit the virus with only one mild cough or sneeze containing infected droplets. It’s easy to forget about such a mild symptom and think you never had symptoms at all. But one cough or sneeze is enough to infect others. Research also suggests that, in confined spaces over prolonged periods of time, the SARS-CoV-2 coronavirus can be spread when you sing, yell, or even talk because infected droplets and aerosols from your mouth can hang in the air indefinitely, exposing people nearby to infection even when you’re asymptomatic, presymptomatic or mildly symptomatic.8 But you don’t have to get into the semantics of deciding if someone is asymptomatic, presymptomatic, or mildly symptomatic, as our obsession with semantics could have a deadly impact. But don’t place too much importance on those three terms. What is important is to follow prevention protocols, which can reduce your risk of contracting the COVID-19 disease to nearly zero: Maintain six feet of social distance at all times. Wear a protective face covering. Wash your hands for 20 seconds throughout the day. Don’t share any utensils. Following these easy steps will help keep us safe. Myth: Pets can’t spread the coronavirus The short explanation is that pet dogs and cats could get the SARS-CoV-2 coronavirus from humans and carry and spread the virus to other humans and animals.9 It’s worth noting that animals are thought to be the sources of all coronaviruses. Although it is rare, scientists suspect the source of COVID-19 was a coronavirus that spread from an animal to a human at a wet market. This was the case with both SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome). In fact, scientists have thought that bats and a type of anteater are the likely source of COVID-19.10 There’s not a lot of research showing exactly how your pets respond to when exposed to the coronavirus. But we do know that animals can get it from humans and spread it.11 Regarding COVID-19, it’s important to treat a pet like any other member of your family and take precautions to stop the SARS-CoV-2 coronavirus to flatten the curve.12 For example, if you have a COVID-19 infection, you can potentially infect your dog with the virus by coughing or sneezing on them. Then, your infected dog, while sitting on your father’s lap, can then cough or sneeze, thus infecting your father by spreading the virus through mucous membranes. So to be on the safe side, pet owners should socially distance their pets too. Don’t let strangers touch your pets while you’re outdoors. Infectious droplets could get into your pet’s mucous membranes or reach their face or paws from other pets. And if you see someone else’s dog or cat, don’t pet them. Cats may be especially problematic when it comes to COVID-19, since cats have cellular membranes that have a specific feature that is similar to one in humans onto which the coronavirus latches onto.13 This means that cats might be as likely as humans to become infected with the SARS-CoV-2 coronavirus from infected respiratory droplets or transmission through the eyes, nose, and mouth. So here’s what you should do to protect your pets and your household: Keep your pets away from infected family members and from other people or their animals outside your home. Don’t let your cats or dogs wander outside beyond your home. Put dogs on a leash at all times outside the house, keeping them 6 feet away from people and animals. Don’t take your pets to places where large groups gather, such as dog parks or indoor pet playgrounds. Myth: All masks provide equal protection from the coronavirus Different masks provide different levels of protection from the SARS-CoV-2 coronavirus. Most localities and public health organizations have recommended wearing a simple cloth face covering in public. This will help protect you from large, infectious respiratory droplets.14,15,16,17,18 Click here to see why particle size matters… But face coverings like cloth masks, bandanas, or gaiters provide limited protection from airborne aerosols in crowded places when social distancing is impossible.19,20,21,22 Although cloth masks offer limited protection to the wearer, cloths masks are an effective strategy as a collective public effort – as long as everyone wears them. The fewer people that wear them, the less likely it is that this collective public effort will be effective. There are higher quality masks that offer the wearer a higher level of protection. A certified N95, FFP2, or KN95 respirator mask is designed to protect the wearer.23 N95 is an American standard mask that filters at least 95% of 0.3 microgram-sized particles. The Chinese standard KN95 mask and the European standard FFP2 mask offer similar protection. In hospital settings, airborne aerosols that contain the coronavirus can build up to high concentrations in spaces where patients are in close quarters with medical staff.24 Worn properly, medical-grade respirator masks filter out most infectious aerosols and ensure that the air that the wearer breathes is virtually free of aerosolized viruses.25 Considering the higher effectiveness of N95, FFP2 or KN95 masks, it also makes sense that individuals, especially those who are at higher risk for severe illness, also benefit from higher-level personal protection. To learn more about face masks, see our piece Face masks 101: Infection control. The takeaway Ask your doctor or a medical professional for the most accurate prevention and treatment information – and pay close attention to trusted sources of health news and information who use rigorous research and science to back up their claims.","

It’s impossible to read about the COVID-19 coronavirus (a serious, often fatal respiratory disease) without running into a few dangerous myths.

But some of these myths can be deadly. So let’s explore three COVID-19 myths to learn about the most widely spread rumors.

Myth: Asymptomatic people can’t spread the coronavirus

Therefore, the WHO acknowledged that asymptomatic people can play a role in spreading tSARS-CoV-2 (which stands for severe acute respiratory syndrome coronavirus 2) responsible for COVID-19.¹

It’s also important to acknowledge that the term “asymptomatic” as used in everyday conversations can actually have three different scientific meanings:

When you’re asymptomatic, you are carrying the virus but show no symptoms. However, you are still able to infect others.
When you’re presymptomatic, you have recently contracted the virus and have yet to show symptoms and are also asymptomatic. You are still able to infect others at this stage of infection and will begin to show mild or severe symptoms.
When you are mildly symptomatic, you do not experience pneumonia associated with COVID-19, but rather mild coronavirus symptoms. You belong to the most infectious types of spreaders, as it is highly likely that you’re out and about.

And several extensive studies suggest that cases of asymptomatic people that test positive for the presence of SARS-CoV-2 in their bodies often turn out to be presymptomatic.^2,3,4 However, all of these “asymptomatic” types of spreaders should be taken seriously.

According to the WHO, there are three primary ways that you can catch COVID-19:

\nbeing coughed or sneezed on by someone with an active infection and symptoms⁵\n
\ntouching a surface that carries infected respiratory droplets and then touching your face (eyes, nose, or mouth)^6,7\n
\nbeing in enclosed spaces where infected airborne particles can build up

You can transmit the virus with only one mild cough or sneeze containing infected droplets. It’s easy to forget about such a mild symptom and think you never had symptoms at all. But one cough or sneeze is enough to infect others.

Research also suggests that, in confined spaces over prolonged periods of time, the SARS-CoV-2 coronavirus can be spread when you sing, yell, or even talk because infected droplets and aerosols from your mouth can hang in the air indefinitely, exposing people nearby to infection even when you’re asymptomatic, presymptomatic or mildly symptomatic.⁸

But you don’t have to get into the semantics of deciding if someone is asymptomatic, presymptomatic, or mildly symptomatic, as our obsession with semantics could have a deadly impact.

But don’t place too much importance on those three terms. What is important is to follow prevention protocols, which can reduce your risk of contracting the COVID-19 disease to nearly zero:

It’s worth noting that animals are thought to be the sources of all coronaviruses.

Although it is rare, scientists suspect the source of COVID-19 was a coronavirus that spread from an animal to a human at a wet market. This was the case with both SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome). In fact, scientists have thought that bats and a type of anteater are the likely source of COVID-19.¹⁰

There’s not a lot of research showing exactly how your pets respond to when exposed to the coronavirus. But we do know that animals can get it from humans and spread it.¹¹ Regarding COVID-19, it’s important to treat a pet like any other member of your family and take precautions to stop the SARS-CoV-2 coronavirus to flatten the curve.¹²

For example, if you have a COVID-19 infection, you can potentially infect your dog with the virus by coughing or sneezing on them. Then, your infected dog, while sitting on your father’s lap, can then cough or sneeze, thus infecting your father by spreading the virus through mucous membranes.

So to be on the safe side, pet owners should socially distance their pets too. Don’t let strangers touch your pets while you’re outdoors. Infectious droplets could get into your pet’s mucous membranes or reach their face or paws from other pets.

And if you see someone else’s dog or cat, don’t pet them.

Cats may be especially problematic when it comes to COVID-19, since cats have cellular membranes that have a specific feature that is similar to one in humans onto which the coronavirus latches onto.¹³

This means that cats might be as likely as humans to become infected with the SARS-CoV-2 coronavirus from infected respiratory droplets or transmission through the eyes, nose, and mouth.

So here’s what you should do to protect your pets and your household:

\nKeep your pets away from infected family members and from other people or their animals outside your home.
\nDon’t let your cats or dogs wander outside beyond your home.
\nPut dogs on a leash at all times outside the house, keeping them 6 feet away from people and animals.
\nDon’t take your pets to places where large groups gather, such as dog parks or indoor pet playgrounds.

Myth: All masks provide equal protection from the coronavirus

Different masks provide different levels of protection from the SARS-CoV-2 coronavirus.

Most localities and public health organizations have recommended wearing a simple cloth face covering in public. This will help protect you from large, infectious respiratory droplets.^{14,15,16,17,18}

Click here to see why particle size matters…

But face coverings like cloth masks, bandanas, or gaiters provide limited protection from airborne aerosols in crowded places when social distancing is impossible.^19,20,21,22

Although cloth masks offer limited protection to the wearer, cloths masks are an effective strategy as a collective public effort – as long as everyone wears them. The fewer people that wear them, the less likely it is that this collective public effort will be effective.

There are higher quality masks that offer the wearer a higher level of protection. A certified N95, FFP2, or KN95 respirator mask is designed to protect the wearer.²³ N95 is an American standard mask that filters at least 95% of 0.3 microgram-sized particles. The Chinese standard KN95 mask and the European standard FFP2 mask offer similar protection.

In hospital settings, airborne aerosols that contain the coronavirus can build up to high concentrations in spaces where patients are in close quarters with medical staff.²⁴

Worn properly, medical-grade respirator masks filter out most infectious aerosols and ensure that the air that the wearer breathes is virtually free of aerosolized viruses.²⁵

Considering the higher effectiveness of N95, FFP2 or KN95 masks, it also makes sense that individuals, especially those who are at higher risk for severe illness, also benefit from higher-level personal protection.

Research on air pollution and viruses goes back many years. In 2003, scientists found that people exposed to high air pollution levels were twice as likely to die from severe acute respiratory syndrome (SARS), as those with less exposure – an 8.9% mortality rate for polluted areas versus 4.08% for less polluted areas.1 It's worth noting that SARS-CoV-1 (severe acute respiratory syndrome coronavirus 1) responsible for the 2003 SARS outbreak has been found to be 80% similar to SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) responsible for the COVID-19 outbreak that began in late 2019. This suggests that research on coronaviruses and air pollution may already have a deep well of research to draw from. The mortality rate of people infected with the SARS coronavirus living in heavily polluted areas was about 8.9%, while those infected who lived in less polluted areas faced a mortality rate of 4.08%. COVID-19 and air pollution Researchers have since dug deeper into why air pollution may increase the risk of death from COVID-19 and other coronavirus infections.A groundbreaking 2020 study looked at three cell receptors in the lungs that the virus uses as entryways into your lungs: the enzyme ACE2 and the proteins DC-SIGN and L-SIGN.2 These receptors keep your basic bodily functions working normally by turning amino acids and sugars into fuel for important processes as follows: ACE2 helps regulate blood pressure DC-SIGN and L-SIGN support immune system responses to disease. Researchers compared how the lungs of smokers and non-smokers responded to COVID-19 infections.They found that ACE2 receptors in smokers’ lungs were more vulnerable to SARS-CoV-2 coronavirus infections than non-smokers. ACE2 receptors in smokers’ lungs were more vulnerable to COVID-19 infections than non-smokers. Lung damage in smokers is very similar to lung damage in people who have breathed air pollution for long periods of time. A 2019 study in the Journal of the American Medical Association found that regular exposure to pollutants like ozone was like smoking a pack of cigarettes a day in terms of lung damage.3 Even areas with relatively low levels of long-term air pollution can be susceptible to higher risks of severe or deadly COVID-19 symptoms from poor air quality. A team of researchers from the Harvard T.H. Chan School of Public Health wanted to find out just how deep the relationship between air pollution and the coronavirus goes.4 So they looked at COVID-19 deaths and average particulate matter, or PM2.5 pollution in over 3,000 U.S. counties that represented 98% of the U.S. population. The researchers found that a PM2.5increase of 1 microgram per cubic meter (𝜇g/m3) increased the risk of severe or deadly COVID-19 symptoms by 8%.

Pollutants disrupt appetite-governance Fine particles, or PM2.5, and ultra fine particles, particles measuring, less than 0.1 microns in diameter, are believed to be the pollutants most responsible for disrupting metabolic function. When you breathe in, particle pollutants irritate the alveoli in your lungs that normally allow oxygen to pass into your blood stream. Consequently, the lining of your lungs releases hormones that make insulin less effective, diverting blood from insulin-sensitive muscle tissue and stopping your body from properly regulating its blood sugar levels. Additionally, particle pollution may cause your body to flood your blood with higher levels of inflammatory molecules called “cytokines”, which trigger immune cells to invade otherwise healthy tissue. According to a 2014 study published in Environmental Health, this response not only interferes with your tissue’s ability to respond to insulin, but the resulting inflammation may also disrupt the hormones and brain processing that govern your appetite.1 This can result in feeling hungry even when you’re totally full or satiated. The additional food you eat to feed your artificial appetite may result in weight gain over time. – The Berkeley researchers found,that air pollution exposure could lead to a 13.6% increase in body mass index (BMI), the most popular metric for a healthy weight.

The researchers periodically weighed the mice and performed tests to analyze their metabolic function. In just 10 weeks, the mice exposed to the polluted air displayed greater volumes of body fat, both around their midsections and around internal organs, and the fat cells were approximately 20% larger in the mice exposed to polluted air. The fatter mice also seemed to have become less sensitive to insulin — one of the first symptoms in the development of type 2 diabetes. Fat cells were approximately 20% larger in the mice exposed to polluted air. Several scientific studies show that humans are susceptible to the same alarming health consequences. Air pollution may lead to health problems A particularly noteworthy study examined the medical records of 62,000 people in Ontario, Canada over a 14-year period.4 The researchers discovered that the risk of developing diabetes increased by roughly 11% for every 10 micrograms of fine particles in a cubic meter of air — this is a disturbing figure considering that PM2.5 pollution in some cities and regions affected by wildfires have been recorded at 500 micrograms per cubic meter of air.5 Wildfire smoke is rarely limited to the immediate vicinity of fire. Smoke can travel over continents and cross oceans, traveling thousands of miles from its source. A 2015 study in PLOS One offered similar evidence of increased hypertension, insulin resistance, and waist circumference in a sample of almost 4,000 people living in a highly polluted area.6 In 2020, University of Colorado at Boulder researchers found that young adults in Southern California experienced a change in the composition of the gut microbiome in connection with their exposure to air pollutants.7 The findings, published in Environment International, determined that ozone had a greater impact on gut microbiome composition than gender, ethnicity, and diet. Young people with greater ozone exposure experienced reduced microbial diversity within the gut. The reduction in diversity included growth in Bacteroides caecimuris; at elevated levels, this bacterial species is associated with higher levels of obesity. Children arevulnerable Scientists are specifically concerned that air pollution may alter the metabolism of infants and young children, making them more likely to become obese as they age. A 2012 longitudinal study published in American Journal of Epidemiology addressed this question by examining the health of nearly 800 children growing up in the Bronx borough of New York City from 1998 to 2006.8 While pregnant, the children’s mothers wore a small backpack for the study that measured air quality during their day. Over the next seven years, the children’s health was monitored at regular intervals. Accounting for other factors like diet and income, children born in the most heavily polluted areas were nearly two and a halftimes likelier to be considered obese, compared to children living in neighborhoods with cleaner air quality. Further supporting these findings, a 2017 study in Pediatric Obesity demonstrated that even in the first six months, babies of mothers living in heavily-polluted areas appear to put on weight more rapidly than those in areas with cleaner air.9 It’s important to be cautious about giving too much weight to these findings. The studies only establish a link between exposure and outcome, but can’t prove that one factor causes another. But researchers continue to uncover key findings that fill those gaps. A 2016 study published in Hypertension tested a small group of subjects in Beijing for two years.10 The researchers discovered that whenever the big city’s notorious smog blanketed the sky, telltale indicators of developing issues like insulin resistance and hypertension peaked — solidifying more concrete evidence that the air quality may be directly linked to metabolic processes that lead to obesity. Air pollution is both global and issue While scientific research continues to uncover the link between air pollution exposure and obesity, what can you do to protect yourself from this potential threat to your health? The scientific community emphasizes that individual, short-term risk posed by poor air quality shouldn’t be understood as the basis for obesity by itself without considering other facets of your lifestyle, such as diet or physical activity. However, given the large numbers of people living in cities plagued with pollution — up to 68% of the world’s population by 2050, according to the United Nations — the long-term risk could be massive.11 When it comes to positively impacting your air quality as well as your weight, focus on the change you can make in your own world. The global air pollution crisis is obviously impossible for a single person to crack. On a global scale, some other measures that could help improve air quality include: monitor your air quality, especially levels of harmful PM2.5 restrict traffic in densely populated urban areas to reduce traffic pollution redesign streets to make them friendlier to pedestrians and cyclists increase investment in renewable energy sources Losing weight is challenging enough without having to worry about invisible pollutants wreaking havoc on your metabolism. You can’t take on the burden of solving the global air quality crisis alone, but you can take control of your indoor air quality and begin making positive changes in your life today. A healthy diet and regular exercise are still the most vital keys to success in your weight-management journey, but a little clean air might help boost your overall health and wellness.","

Slimming down is tough.

Even if you exercise regularly and eat well, you may still get different (and possibly disappointing) results than someone who follows the same regimen.

What causes this disparity? There are many possible answers, but one of the least visible causes may be going straight into your body without you knowing it – air pollution.

A 2015 study in PLOS One offered similar evidence of increased hypertension, insulin resistance, and waist circumference in a sample of almost 4,000 people living in a highly polluted area.⁶

In 2020, University of Colorado at Boulder researchers found that young adults in Southern California experienced a change in the composition of the gut microbiome in connection with their exposure to air pollutants.⁷ The findings, published in Environment International, determined that ozone had a greater impact on gut microbiome composition than gender, ethnicity, and diet.

Young people with greater ozone exposure experienced reduced microbial diversity within the gut. The reduction in diversity included growth in Bacteroides caecimuris; at elevated levels, this bacterial species is associated with higher levels of obesity.

Children arevulnerable

Scientists are specifically concerned that air pollution may alter the metabolism of infants and young children, making them more likely to become obese as they age.

A 2012 longitudinal study published in American Journal of Epidemiology addressed this question by examining the health of nearly 800 children growing up in the Bronx borough of New York City from 1998 to 2006.⁸

While pregnant, the children’s mothers wore a small backpack for the study that measured air quality during their day. Over the next seven years, the children’s health was monitored at regular intervals.

Accounting for other factors like diet and income, children born in the most heavily polluted areas were nearly two and a halftimes likelier to be considered obese, compared to children living in neighborhoods with cleaner air quality.

Further supporting these findings, a 2017 study in Pediatric Obesity demonstrated that even in the first six months, babies of mothers living in heavily-polluted areas appear to put on weight more rapidly than those in areas with cleaner air.⁹

It’s important to be cautious about giving too much weight to these findings. The studies only establish a link between exposure and outcome, but can’t prove that one factor causes another.

But researchers continue to uncover key findings that fill those gaps.

A 2016 study published in Hypertension tested a small group of subjects in Beijing for two years.¹⁰ The researchers discovered that whenever the big city’s notorious smog blanketed the sky, telltale indicators of developing issues like insulin resistance and hypertension peaked — solidifying more concrete evidence that the air quality may be directly linked to metabolic processes that lead to obesity.

Air pollution is both global and issue

While scientific research continues to uncover the link between air pollution exposure and obesity, what can you do to protect yourself from this potential threat to your health?

The scientific community emphasizes that individual, short-term risk posed by poor air quality shouldn’t be understood as the basis for obesity by itself without considering other facets of your lifestyle, such as diet or physical activity.

However, given the large numbers of people living in cities plagued with pollution — up to 68% of the world’s population by 2050, according to the United Nations — the long-term risk could be massive.¹¹

When it comes to positively impacting your air quality as well as your weight, focus on the change you can make in your own world.

The global air pollution crisis is obviously impossible for a single person to crack. On a global scale, some other measures that could help improve air quality include:

\nmonitor your air quality, especially levels of harmful PM2.5
restrict traffic in densely populated urban areas to reduce traffic pollution
redesign streets to make them friendlier to pedestrians and cyclists
increase investment in renewable energy sources

Losing weight is challenging enough without having to worry about invisible pollutants wreaking havoc on your metabolism.

You can’t take on the burden of solving the global air quality crisis alone, but you can take control of your indoor air quality and begin making positive changes in your life today.

A healthy diet and regular exercise are still the most vital keys to success in your weight-management journey, but a little clean air might help boost your overall health and wellness.

UV light as used in a UV air cleaner is designed to disinfect potentially infectious living, organic bacteria and inorganic viral material from the air flowing through the purifier. UV light’s secret weapon against bacteria and viruses? DNA damage – just like UV rays from the sun can damage your skin cells and cause skin cancer, UV light can damage and sometimes destroy the DNA that makes up bacterial and viral matter (2). Just like UV rays from the sun can damage your skin cells, UV light can damage and sometimes destroy the DNA that makes up bacterial and viral matter. There are two main ways that UV light accomplishes this. First, bacteria are living organisms, and UV light damages their DNA. When bacterial DNA is damaged, bacteria can’t complete two key reproductive processes known as transcription and replication that allows them to make more bacteria (3).This keeps them from growing, reproducing, and forming enormous colonies throughout your body that are the source of many infectious diseases. By contrast, viruses aren’t really living – they’re made up of DNA and RNA (ribonucleic acid, a molecule similar to DNA)material that viruses use to invade the DNA strands of living cells, infecting them with their own contaminated viral DNA and making them reproduce that infected DNA in huge quantities. This is how viral conditions like colds, flu, and measles spread and become so infectious so fast (4).With sufficient contact time, UV light inactivates this DNA and RNA material, stopping them from ever assaulting organic cells. But do UV air filters actually work? UV light alone can inactivate infectious biocontaminants like bacteria and viruses to a certain degree – so it should work in an air purifier, right? But the specific mechanisms of UV air cleaners aren’t as effective as they might sound. Here’s why (5) (6) (7) (8) (9) (10): Bacteria and viruses need extended periods of UV light exposure before they’re disinfected, often up to several hours.Air often flows through UV air purifiers too fast for the UV rays to make any difference. Some bacteria can regenerate and infect you again even after being disinfected by UV light. UV light does nothing for particles. UV light doesn’t destroy particulate matter like PM2.5 and ultrafine particles (UFPs), so most of these dangerous pollutants will still come right through into your air if the particle filtration mechanism isn’t good enough. Many UV air purifiers are also ozone generators. Just like ozone in the earth’s atmosphere reacts with UV rays from the sun, the light and heat in some UV air purifiers can also generate heat that turns free-floating molecules of oxygen (O and O2) and water (H2O) into dangerous ground-level ozone (O3). UV light can burn your skin and damage your eyes. Even brief UV exposure can cause permanent skin and eye damage as well as cancer. And it’s worth noting that ozone particles used in some of these UV air cleaners to charge pollutant particles and take them out of the air produce ground-level ozone. This type of ozone can be extremely toxic – even short-term exposure can cause a cascade of respiratory symptoms, and long-term exposure has been linked to numerous deadly health conditions (11) (12). Find your perfect air quality solution SHOP NOW The ABC’s of UV light Not all UV light is created equal – only certain types are utilized in UV air filters. Here’s what you need to know: UV light comes in three distinct forms, distinguished by their wavelengths, that each have different effects on organic matter. UV-A UV-A rays are about 315–400 nanometers (nm), the longest wavelength of the three UV ray types with photons (or light particles) that vibrate just a little faster than those in visible light. This type of UV light isn’t typically used in any air purifiers or similar technology. But over 95% of the rays from sunlight that make it to the surface of the earth fall into this category (13).UV-A rays are the most likely to penetrate through your skin to cause skin damage and cancer with long-term exposure (14). UV-B UV-B rays are a little shorter than UV-A rays at about 280–315 nm. Their photons vibrate even faster than those in UV-A rays, giving them more energy to damage DNA. But because of their shorter wavelengths, most of them don’t pass through the upper layers of the atmosphere. The small percentage of UV-B rays that do pass through the atmosphere, however, are the ones most directly linked to skin cancer (15). UV-C UV-C light wavelengths measure between 100 and 280 nm. UV-C is the kind of UV light that’s used in most, if not all, UV air purifiers. These UV rays have the shortest wavelengths and transmit the most energy, giving them a lot of potential to damage and kill tiny microbes and cells – that’s why they’re used in UV air cleaners to kill bacteria and viruses, especially in a form called ultraviolet germicidal irradiation (UVGI) (16). But UV-C light is also the most dangerous of the three. Because of its high energy and intensity, even short-term exposure to UV-C light from a UVC air purifier (or UV-C air purifier) can cause damage to your eyes and skin – and the longer you’re exposed, the more severe the damage can be. UV technology requires significant contact time to “kill” biocontaminants There’s another major consideration to keep in mind when you think about using UV light for killing viruses and bacteria – it takes a long time for UV light to kill or inactivate even small amounts of airborne pathogens or surface contaminants. The amount of energy and time it takes UV light to destroy viruses and bacteria is measured in millijoules per square centimeter (mJ/cm2), where one joule (1000 millijoules) equals about one second. And different contaminants require different durations of UV light exposure to be completely eradicated – here’s what the research says about how long it takes UV light to effectively destroy just one square centimeter of some common viruses and bacteria(17) (18) (19): Influenza virus: about 6.6 seconds E. Coli: about 6.6 seconds Staphylococcus aureus: about 6.6 seconds Aspergillus mold spores: 8.8 to 33 seconds SARS-CoV: around 60 seconds or more SARS-CoV-2 (COVID-19 coronavirus): up to 60 seconds That may not seem like a long time, but when you cough or sneeze, you produce anywhere from 900 to over 300,000 of these kinds of infected particles at a time, potentially filling hundreds of square centimeters of area in the air of a room(20) (21). And a UVC air purifier needs from 6 seconds up to 1 minute or more just to kill infected particles in just one of these square centimeters. Given that air often passes through an air purifier quickly (spending less than half a second in the air purifier itself), infected particles can fly past UV light largely unscathed and still infectious. And that’s assuming that your UV air cleaner uses the right wavelength of UV light at a high enough intensity to effectively inactive airborne biocontaminants – but most UV air purifiers that are sold as safe for use at home only generate low doses of UV light, and they may take even longer to kill even smaller amounts of biocontaminants (22). This means that a UV air filter can take several hours or more to kill or inactivate infected airborne contaminants from the air in a room (assuming that someone doesn’t cough, sneeze, or breathe again and add even more infected particles to the air). When you cough or sneeze, you produce anywhere from 900 to over 300,000 infected particles, filling hundreds of square centimeters of air in a room – and a UV air purifier needs from 6 seconds to a minute or more to kill just one square centimeter’s worth of infected particles. In short, a UVC air purifier may be able to capture and kill or inactive some thousands of these infected particles, but hundreds or thousands of particles can remain in your air for hours before being killed, able to be breathed in and cause infections. If biocontaminants are “killed” by UV, can they still harm me? The short answer here is yes. Unlike typical air purifiers, UV air purifiers don’t actually remove biocontaminants like viruses and bacteria from your air – they inactivate them as they pass under concentrated UV beams, dismantling the molecular bonds that comprise the DNA of these organisms and sending the inactivated DNA back into the air. But biocontaminants are typically only partially inactivated by UV light, with the potential of coming back to life – a state called viable but nonculturable (VBNC). In a VBNC state, biocontaminants go dormant after UV exposure, but can “wake up” to regenerate again after some time, even at high doses of UV light up to 300 mJ/cm2 (23). This means that plenty of infectious biocontaminant particles go right back into the air after passing through the UV light – some are inactivated and harmless, but many are still actively infectious or can become infectious again. And the level of biocontaminants “killed” by UV light depends largely upon several critical factors in the design of the UV mechanism used in the UVC air cleaner itself. In general, it’s believed that 40 mJ/cm2 of UV light at a wavelength of 0.254 microns (commonly used in UV air purifiers) can kill up to 99.99% of almost any airborne biocontaminant (24). But viruses in particular have been shown to need a much wider spectrum ranging from 0.2 to 0.315 microns for effective inactivation—different wavelengths are effective for different types of viruses due to the specific interactions of UV light with various viral DNA proteins—in addition to requiring several seconds of exposure for any level of inactivation. Most UV air purifiers use 40 mJ/cm2 of UV light at a wavelength of 0.254 microns to inactivate viruses. But viruses need a much wider spectrum from 0.2 to 0.315 microns for effective inactivation due to the specific interactions of UV light with various viral DNA proteins. So even in theory, a UVC air purifier needs a specific wavelength and a specific amount of exposure time to even partially inactivate airborne biocontaminants – it’s not one size fits all. And in practice, most UV air filters don’t meet the proper wavelength and exposure requirements to sufficiently protect you from the most dangerous viruses and bacteria. You’d need a perfect storm of the right UV wavelength, sufficient exposure time, and the use of other air filtration technologies for UV air purification to truly remove biocontaminants from the air. Should I get a UV air purifier? Short answer: No. Don’t buy a UV light air purifier or any air purifiers that use UV light as a key part of their purification mechanism. It’s dangerous and doesn’t work that well, especially without the use of other proven air filtration methods. Long answer: UV disinfection simply doesn’t work at the velocity that air needs to be pulled through a purifier to filter pollutants. Bacterial and viral matter need to be exposed to UV light for a certain amount of time, sometimes as long as several hours at a time, so a few seconds or less under a UV light, no matter how strong, won’t do much to remove microbial pollutants. UV light somewhat disinfects but doesn’t purify air, and research shows that UV’s disinfection potential for air may be exaggerated. What should I do to clean my air? Here are some time-tested and proven tips for improving indoor air quality that don’t rely on ineffective technologies. Use a high-efficiency room air purifier For typical rooms that are several hundred square feet or so, a room air purifier like the HealthPro Plus can remove up to 99.5% of pollutants down to 0.003 microns (10 times smaller than the average bacterium or virus) several times an hour, far outperforming UV or standard HEPA air purifiers. A room air purifier is recommended for spaces like bedrooms, home offices, kitchens, home gyms, and other spaces where you spend a lot of time and need the purest air possible for restful sleep, unhindered cognitive function, or peak physical performance. Use a whole-house air purifier Concerned about air quality throughout your household? A UV light air purifier for heating, ventilation, and air conditioning (HVAC)systems isn’t the solution – a high-performance whole-house air filtration system is much more effective. The Perfect 16 whole-house air purifier fits into your home’s existing HVAC units to draw in air, purify it of up to 96.7% of particulate pollutants down to 0.3 microns and up to 85% of particles down to 0.003 microns with over 170 square feet of filter media, and recirculate the air through your home’s supply ductwork at up to 2,000 cfm so that every room in your home has fresh, clean, medical-grade air. A whole-house air purifier takes up no space, adds no noise to your HVAC operation, and reduces your electricity bill through patented Advanced Microfiber (AMF) technology that maximizes filter surface area for pollutant removal while reducing air resistance so that purification is easy on your HVAC fan motor. Use a personal air purifier Need high-efficiency air purification on the go? The Atem 5-in-1 personal air purifier directs clean air into your breathing zone for instant clean air wherever you need it. Air quality can be unpredictable, and typical portable “air purifiers” often use dangerous ionization or UV technology that does little to clean the air in your workspace, your car interior, or next to your bed. The Atem uses HyperHEPA filtration technology to remove up to 99% of particles down to 0.003 microns from the air you’re breathing right now, virtually eliminating pollutant particles without creating harmful byproducts like ozone. An optional HyperHEPA Plus filter uses an additional layer of activated carbon to remove over 250 types of gases from ambient indoor and outdoor air, including chemicals and compounds like formaldehyde that originate from off-gassing of building materials and upholstery. The takeaway UV light can help provide an additional layer of defense against viruses, bacteria, and microbes in the air and on surfaces. But due to the length of exposure and intensity required to effectively kill airborne biocontaminants, UV light is generally ineffective in air purifiers available for homes and works best in controlled medical environments. According to the Centers for Disease Control and Prevention (CDC), UV air purifiers, whether they’re called ultraviolet air purifiers, UVC air purifiers, or UV-C air purifiers (or filters or cleaners), can be used as part of an air purification strategy, but shouldn’t be relied on as a sole measure of airborne biocontaminant control (25). High-efficiency air purification with dense filtration material that can capture the tiniest airborne biocontaminants and pathogens, such as viruses and bacteria, is much safer, more effective, and more reliable than UV air purifiers.

No. Don’t buy a UV light air purifier or any air purifiers that use UV light as a key part of their purification mechanism. It’s dangerous and doesn’t work that well, especially without the use of other proven air filtration methods.

Long answer:

UV disinfection simply doesn’t work at the velocity that air needs to be pulled through a purifier to filter pollutants. Bacterial and viral matter need to be exposed to UV light for a certain amount of time, sometimes as long as several hours at a time, so a few seconds or less under a UV light, no matter how strong, won’t do much to remove microbial pollutants.

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

What should I do to clean my air?

Here are some time-tested and proven tips for improving indoor air quality that don’t rely on ineffective technologies.

Use a high-efficiency room air purifier

For typical rooms that are several hundred square feet or so, a room air purifier like the HealthPro Plus can remove up to 99.5% of pollutants down to 0.003 microns (10 times smaller than the average bacterium or virus) several times an hour, far outperforming UV or standard HEPA air purifiers.

$\"airflow$

A room air purifier is recommended for spaces like bedrooms, home offices, kitchens, home gyms, and other spaces where you spend a lot of time and need the purest air possible for restful sleep, unhindered cognitive function, or peak physical performance.

Use a whole-house air purifier

Concerned about air quality throughout your household? A UV light air purifier for heating, ventilation, and air conditioning (HVAC)systems isn’t the solution – a high-performance whole-house air filtration system is much more effective.

The Perfect 16 whole-house air purifier fits into your home’s existing HVAC units to draw in air, purify it of up to 96.7% of particulate pollutants down to 0.3 microns and up to 85% of particles down to 0.003 microns with over 170 square feet of filter media, and recirculate the air through your home’s supply ductwork at up to 2,000 cfm so that every room in your home has fresh, clean, medical-grade air.

A whole-house air purifier takes up no space, adds no noise to your HVAC operation, and reduces your electricity bill through patented Advanced Microfiber (AMF) technology that maximizes filter surface area for pollutant removal while reducing air resistance so that purification is easy on your HVAC fan motor.

Use a personal air purifier

Need high-efficiency air purification on the go? The Atem 5-in-1 personal air purifier directs clean air into your breathing zone for instant clean air wherever you need it.

Air quality can be unpredictable, and typical portable “air purifiers” often use dangerous ionization or UV technology that does little to clean the air in your workspace, your car interior, or next to your bed.

The Atem uses HyperHEPA filtration technology to remove up to 99% of particles down to 0.003 microns from the air you’re breathing right now, virtually eliminating pollutant particles without creating harmful byproducts like ozone.

An optional HyperHEPA Plus filter uses an additional layer of activated carbon to remove over 250 types of gases from ambient indoor and outdoor air, including chemicals and compounds like formaldehyde that originate from off-gassing of building materials and upholstery.

The takeaway

UV light can help provide an additional layer of defense against viruses, bacteria, and microbes in the air and on surfaces.

But due to the length of exposure and intensity required to effectively kill airborne biocontaminants, UV light is generally ineffective in air purifiers available for homes and works best in controlled medical environments.

According to the Centers for Disease Control and Prevention (CDC), UV air purifiers, whether they’re called ultraviolet air purifiers, UVC air purifiers, or UV-C air purifiers (or filters or cleaners), can be used as part of an air purification strategy, but shouldn’t be relied on as a sole measure of airborne biocontaminant control (25).

High-efficiency air purification with dense filtration material that can capture the tiniest airborne biocontaminants and pathogens, such as viruses and bacteria, is much safer, more effective, and more reliable than UV air purifiers.

Do you ever wonder what gives smog its grotesque brown hue?

The answer: nitrogen oxides.

Nitrogen oxides, collectively called NOx, are a family of poisonous, highly reactive gases. Three of the most notorious nitrogen oxides are:1

nitric oxide (NO)
nitrogen dioxide (NO₂)
nitrous oxide (N₂0)

NOx is a powerful oxidizing agent. It plays a significant role in the atmospheric reactions with volatile organic compounds (VOCs) that produce smog on hot summer days.²

NOx is also a major part of acid rain and contributes considerably to global climate change.

Health effects of NOx pollution

NOx pollution isn’t just offensive to look at — it’s also toxic to breathe. Short-term exposure to nitrogen oxides can cause a variety of serious health effects, including:³

irritation of the respiratory system, eyes, and skin
aggravation of respiratory diseases, especially asthma\n
coughing and choking
nausea
headache
abdominal pain
difficulty breathing

Long-term exposure to low levels of NOx can cause asthma and respiratory infections. The health effects from very high concentrations of nitrogen oxides can include:

death
genetic mutations
harm to a developing fetus
decreased female fertility
spasms
swelling of the throat

Significant sources of NOx pollution

Volcanoes, oceans, and lightning strikes naturally produce nitrogen oxides. But the prominent presence of this noxious pollutant is largely attributed to man-made sources like vehicle exhaust gases and emissions from electrical power plants.⁴

Most governments concentrate most of their NOx-reducing initiatives on regulating vehicle and industrial emissions because these are traditionally the most significant sources of NOx pollution.

But there’s been a flurry of recent research that reveals another huge source of NOx emissions that’s been underreported — agriculture.

Agriculture’s role in NOx

Big Agriculture (a term for the corporatization of agriculture) regularly gets blowback for employing farming practices that undermine the environment, but its excessive use of fertilizer plays the biggest role in increasing NOx pollution.

How does excessive fertilizer use add to NOx pollution?

Farmers add fertilizer to their crops (basically a load of nitrates) because plants use nitrogen to produce chlorophyll, which is essential for growth. Microbes in the soil feed on nitrate-rich organic matter in the soil not consumed by plants. These microbes produce NOx during their feeding frenzy that contaminates the air.⁵

This may not seem like a big deal since microbes are microscopic – how much NOx could these tiny soil dwellers possibly produce? Well, multiply the thousands of microbes in the soil by millions of acres of farmland, and the amount of NOx released into the air reaches astounding levels.

California’s Central Valley: A breeding ground for NOx

Nowhere else is this link between NOx pollution and widespread fertilizer application more clear than in California, home to one of the most prosperous agricultural regions in the world.

Researchers from the University of California, Davis found that California could have 20% to 51% more NOx pollution than previously thought, thanks to its farmland. That would mean that NOx pollution from farming could result in up to 40% of the total NOx pollution in the Golden State.⁶

This represents a dramatic departure from the California Air Resources Board’s (CARB) estimate that only 3.8% of the state’s total NOx pollution derives from farmland soil.⁷

To obtain these figures, the UC Davis research team, funded by the National Science Foundation, took soil samples and flew over cropland on a plane equipped with a gas-sampling tool to take measurements of NOx emissions.

The study found that six of the worst air quality districts in the US were found in the area of California covered by the study.⁸

The smog that has such a stranglehold in these areas may help explain why children in the Central Valley suffer the highest rates of asthma in California — and the San Joaquin Valley region within the Central Valley, where one in six children have asthma, has the highest rate in the entire country.⁹

The Central Valley is home to a significant number of underserved communities, which are more acutely impacted by air pollution due to greater levels of exposure than are other communities. Additionally, these communities are also more vulnerable to the health effects of air pollution exposure than other groups at the same levels of exposure.¹⁰

Excessive fertilizer use is a global air quality issue

Irresponsible large-scale fertilizer use doesn’t just affect the air quality in California — approximately 30-40% of all NOx pollution worldwide is a result of excess fertilizer in farm fields.¹¹

A study conducted by researchers from the University of California, Berkeley used nitrogen isotope data to find the unmistakable fingerprint of fertilizer use in archived air samples from Antarctica and Tasmania.

The air samples showed a long-term trend in isotopic composition that confirms that nitrogen-based fertilizer is mainly responsible for a 20% increase in atmospheric NOx since the Industrial Revolution.¹²

Using fertilizer responsibly

Since NOx is produced mostly from excess available nitrogen in soils, one way to reduce NOx emissions is to apply fertilizer sensibly — adding just enough at the right place and time to meet crop demands but avoiding excess amount left over. This measure not only decreases fertilizer costs to producers but also reduces the amount of nitrogen that’s lost through excess fertilizer application.

Fertilizer can be used more efficiently by:¹⁴

adjusting fertilizer rates to coincide with plant needs
placing fertilizer near plant roots (but not too deep in the soil)
applying fertilizers to certain plants, such as turfgrass, twice or more a year, rather than only once¹⁵\n
using slow-release forms

Other farming practices that can sometimes reduce NOx emissions on farms include:

using manure efficiently (less NOx is released from manure)
using cover crops (sown between successive crops) to remove excess available nitrogen
adjusting tillage intensity (occasionally, no-till practices can reduce emissions)

Fertilizer isn’t inherently bad for the environment – it’s been used for thousands of years without leaving lasting impacts on the planet.

But using it wisely and taking measures to reduce the impact of NOx pollution from fertilizer is key to making sure that fertilizer can continue to support global agricultural efforts without harming our health.

And if you’re concerned that local agricultural practices are affecting your community’s air quality, go to local city council meetings and make your voice heard.

Individual city governments are often close collaborators with big agricultural companies whose farming practices affect local air pollution, so going straight to the source of your local government’s decision-making can often be the beginning of a huge, positive change.

How does one measure pollution? Here’s how to reduce your air pollution exposure and how it can improve your quality of life.","You probably don’t always notice when air pollution affects your health. But the effects of air pollution can add up over a lifetime. And despite what many say, there is no safe level of air pollution. As air quality around the world worsens from industrial pollution, wildfires, and climate change, millions of us are taking notice. Monitoring the air quality is not just smart – some say it might be critical to your personal health. Many people monitor their air quality with websites and/or mobile apps. Even if you haven’t personally used air quality data, you’ve probably been affected by it. In fact, in the United States, many schools keep kids from playing outdoors when poor air quality is recorded by the Air Quality Index (AQI).1 Additionally, in China, extreme levels of airborne pollutants regularly make headlines.2 But getting trustworthy air quality data can be difficult. Different countries use different standards, and the data shown at any given time may not be up to date or accurately reflect the levels of air pollution you’re exposed at the time. So does it matter where you get your air quality data from? The short answer is a resounding yes – getting accurate data on a daily (or even hourly) basis can make a huge difference in your health. That’s why it’s crucial to have the most accurate air quality data possible, so that you can protect yourself and your family from real-time air pollution exposure. So here is what you need to reduce your personal air pollution exposure: real-time, hyperlocal data that shows you exactly what’s in the air you’re breathing. How do I understand and interpret air quality data? The World Health Organization (WHO) regularly establishes a set of air pollution standards that it calls “Guidelines” for different types of air pollution in different environments.3 To do this, the WHO sets a guideline value called a mean (or average) that establishes a ceiling for reasonable levels of exposure to a specific air pollutant for a defined period, such as for a 24-hour period or during an entire year. The WHO considers anything above the annual mean value of 10 micrograms per cubic meter (μg/m3) for exposure to particulate matter smaller than 2.5 microns (also known as PM2.5) unsafe and unacceptable and may take specific policy actions against areas with air pollution that goes beyond the guideline values. In fact, PM2.5 is proven to be dangerous to your health, even in small amounts. Research has shown the impact that PM2.5 has on human health – a review in Particle and Fibre Toxicology of 27 important studies on particulate matter published between 2005 and 2017 found that even the short-term inflammation caused by exposure to PM2.5 can significantly increase the risk of DNA damage, cancer, and the symptoms of many heart and respiratory conditions, including asthma and pneumonia.4 This means that even exposure to PM well under the WHO guidelines can still have a long-term impact on your health. As already mentioned, there’s no safe level of air pollution. But this yearly 10 μg/m3 mean is the absolute maximum acceptable level of PM2.5 by WHO standards. Anything beyond that is considered a dangerous level of PM2.5 exposure. So how do I reduce my daily air pollution exposure? It’s important that you reduce your current air pollution exposure every chance you get – and this becomes a lot easier when you have access to hyperlocal data in your immediate area that can inform how you reduce your exposure on a real-time basis.5 Here are some ways that you can take action right now to reduce your daily air pollution exposure. Wake up and check your air quality Use the AirVisual air quality app to access real-time air quality data and prevent yourself from being exposed to air pollution in the first place, such as by shutting windows to keep outdoor pollutants from getting into your home. The AirVisual app shows you exactly how much air pollution you’re exposed to at home, at work, and outdoors (based on locations that you set in the app) so that you can see you’re your regular exposure looks like as well as when it improves.

You probably don’t always notice when air pollution affects your health.

But the effects of air pollution can add up over a lifetime. And despite what many say, there is no safe level of air pollution.

As air quality around the world worsens from industrial pollution, wildfires, and climate change, millions of us are taking notice. Monitoring the air quality is not just smart – some say it might be critical to your personal health. Many people monitor their air quality with websites and/or mobile apps.

Even if you haven’t personally used air quality data, you’ve probably been affected by it. In fact, in the United States, many schools keep kids from playing outdoors when poor air quality is recorded by the Air Quality Index (AQI).¹ Additionally, in China, extreme levels of airborne pollutants regularly make headlines.²

$\"Air$

But getting trustworthy air quality data can be difficult. Different countries use different standards, and the data shown at any given time may not be up to date or accurately reflect the levels of air pollution you’re exposed at the time.

So does it matter where you get your air quality data from? The short answer is a resounding yes – getting accurate data on a daily (or even hourly) basis can make a huge difference in your health.

That’s why it’s crucial to have the most accurate air quality data possible, so that you can protect yourself and your family from real-time air pollution exposure.

So here is what you need to reduce your personal air pollution exposure: real-time, hyperlocal data that shows you exactly what’s in the air you’re breathing.

How do I understand and interpret air quality data?

The World Health Organization (WHO) regularly establishes a set of air pollution standards that it calls “Guidelines” for different types of air pollution in different environments.³

To do this, the WHO sets a guideline value called a mean (or average) that establishes a ceiling for reasonable levels of exposure to a specific air pollutant for a defined period, such as for a 24-hour period or during an entire year.

The WHO considers anything above the annual mean value of 10 micrograms per cubic meter (μg/m3) for exposure to particulate matter smaller than 2.5 microns (also known as PM2.5) unsafe and unacceptable and may take specific policy actions against areas with air pollution that goes beyond the guideline values.

In fact, PM2.5 is proven to be dangerous to your health, even in small amounts.

Research has shown the impact that PM2.5 has on human health – a review in Particle and Fibre Toxicology of 27 important studies on particulate matter published between 2005 and 2017 found that even the short-term inflammation caused by exposure to PM2.5 can significantly increase the risk of DNA damage, cancer, and the symptoms of many heart and respiratory conditions, including asthma and pneumonia.⁴

This means that even exposure to PM well under the WHO guidelines can still have a long-term impact on your health.

As already mentioned, there’s no safe level of air pollution. But this yearly 10 μg/m³ mean is the absolute maximum acceptable level of PM2.5 by WHO standards. Anything beyond that is considered a dangerous level of PM2.5 exposure.

So how do I reduce my daily air pollution exposure?

It’s important that you reduce your current air pollution exposure every chance you get – and this becomes a lot easier when you have access to hyperlocal data in your immediate area that can inform how you reduce your exposure on a real-time basis.⁵

Here are some ways that you can take action right now to reduce your daily air pollution exposure.

Wake up and check your air quality

Use the AirVisual air quality app to access real-time air quality data and prevent yourself from being exposed to air pollution in the first place, such as by shutting windows to keep outdoor pollutants from getting into your home.

The AirVisual app shows you exactly how much air pollution you’re exposed to at home, at work, and outdoors (based on locations that you set in the app) so that you can see you’re your regular exposure looks like as well as when it improves.

The AirVisual app also gives you a 72-hour air quality history and forecast so that you know what to expect and can plan accordingly.

You can also help your family monitor their air quality at home by setting up an air quality monitor like the AirVisual Series outdoors and indoors.

AirVisual Series air quality monitors use hyperlocal sensor to assess air quality in your immediate environment, such as inside your house or in an outdoor area like your backyard. Then, they provides specific recommendations for reducing your air pollution exposure based on your real-time air quality data.

This air quality monitor also displays hyperlocal data alongside live, outdoor air pollution data from validated air quality sources, including other public AirVisual Series monitors. It allows you to put your data into context with larger air pollution patterns.

Indoor and outdoor air quality can vary significantly, so being able to compare your indoor data to what awaits you outdoors can help you better plan ahead to reduce your air pollution exposure.

If you have health insurance coverage, it’s likely that not all your medical expenses are covered by your plan.

However, a flexible spending account, or FSA, can save you considerable cash on eligible medical-related expenditures, procedures, and services that you would typically have to pay for out of pocket — including your IQAir air purifier.

Here are the things you need to know to get your air purifier covered by your FSA.

What is a flexible spending account (FSA)?

There are a few types of flexible spending accounts, but the most common is the medical expense FSA, also known as the healthcare FSA.

The medical expense FSA is a pre-tax medical benefits account offered by many employers that lets you set aside money to pay for eligible medical expenses that aren’t covered by your insurance plan. The money is deducted from your paycheck before taxes are assessed, and you then use funds in your FSA to cover the cost of medical expenses, including:

medical co-pays
deductibles
approved medical devices and equipment like air purifiers

Some companies may also contribute to your FSA, but they are not required to. Your HR department or insurance provider should be able to provide more information on the company’s policy.

It’s also important to note that the Internal Revenue Service (IRS) establishes a limit on the amount of money that you can deposit into an FSA account every year.¹

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

","When choosing an air purifier, one of the first numbers people encounter is CADR—but it is also one of the most misunderstood. CADR, or Clean Air Delivery Rate, measures how quickly an air purifier can clean the air in a space. It is often used to compare different models, but on its own it does not reflect how an air purifier performs in real-world conditions over time. CADR focuses on short-term performance—how quickly clean air is delivered under specific conditions—rather than how long that performance can be maintained. Understanding how CADR works—and how it differs from other metrics like CCM—can make it easier to choose a system that matches both the size of a space and how performance will hold over time. What CADR actually measures CADR reflects how quickly an air purifier removes particles from the air. It combines airflow and filter efficiency to estimate how fast clean air is delivered within a given space. In practical terms, this means CADR indicates how quickly airborne particles can be cleared—but not how consistently that performance will hold over time. CADR measures the removal rate of airborne particles as small as 0.09 microns to as large as 11 microns (1)(2). It reflects how filter efficiency and airflow interact within a given space, but is limited to measuring performance speed rather than long-term usage. CADR is often presented alongside CCM, but the two metrics reflect very different aspects of performance. CADR focuses on how quickly clean air is delivered, while CCM indicates how much pollution a system can handle before its performance begins to decline. The limitation of CADR: Speed vs long-term performance While CADR is commonly used to compare how quickly an air purifier works, it does not indicate how performance will hold over time. As filters load with particles and gases, airflow and efficiency can change—something CADR does not capture.

What CADR actually measures

CADR reflects how quickly an air purifier removes particles from the air. It combines airflow and filter efficiency to estimate how fast clean air is delivered within a given space.

In practical terms, this means CADR indicates how quickly airborne particles can be cleared—but not how consistently that performance will hold over time.

CADR measures the removal rate of airborne particles as small as 0.09 microns to as large as 11 microns (1)(2). It reflects how filter efficiency and airflow interact within a given space, but is limited to measuring performance speed rather than long-term usage.

CADR is often presented alongside CCM, but the two metrics reflect very different aspects of performance. CADR focuses on how quickly clean air is delivered, while CCM indicates how much pollution a system can handle before its performance begins to decline.

The limitation of CADR: Speed vs long-term performance

While CADR is commonly used to compare how quickly an air purifier works, it does not indicate how performance will hold over time.

As filters load with particles and gases, airflow and efficiency can change—something CADR does not capture. Many air purifiers perform well when new but lose effectiveness as filters become saturated.

As a result, CADR alone gives an incomplete—or even misleading—picture of how an air purifier will perform outside of controlled test conditions.

CADR vs CCM: Speed vs endurance

While CADR measures speed, CCM focuses on endurance. It tracks how much pollution an air purifier can remove over time before its performance begins to decline.

CCM ratings are grouped into standardized tiers for particulate matter (P) and formaldehyde (F), which indicate how much pollution an air purifier can handle before its performance begins to decline. Higher tiers represent greater long-term filtration capacity and more stable performance over time.

Learning that starts with context

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

The program moves between history, science, and present-day air quality.

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

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

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

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

How wildfire smoke behaves Many factors affect wildfire smoke behavior, such as: weather geographical terrain the stage of the fire wind Use the live, interactive air quality map below to see how weather, wind, and location can impact the behavior of wildfire smoke near you. Windy conditions generally cause smoke to mix with larger volumes of air to lower smoke concentrations. However, strong winds also can spread fires more quickly, causing larger fires with greater impact. Regional weather can be the dominant determinant in how a fire behaves as well as how smoke affects surrounding areas. However, regional weather systems can spread fires quickly and result in larger fires with more smoke generated, creating the potential for even greater impacts. Strong regional weather systems can also dominate a fire’s behavior for days and be the determining factor of where and how smoke will affect an area. Smoke can travel for miles beyond its source.

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

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.

The home air purifier market has undergone many shifts and starts in its decades-long history as an affordable solution for indoor air quality. Along with those shifts have been seemingly ground breaking advancements in filtration technologies that may seem like the next revolution in air purification.

But not all air purifiers safely clean the air.

Not all air purifiers safely clean the air.

Let's take an evidence-based approach to the industry and separate the fact from the fiction.

What should I look for in an air purifier?

Before we examine the various air purifiers on the market with a critical eye, it’s essential to have a solid understanding of what does make a good air purifier.

$\"Air$

1. HEPA filters are the standard for the industry.

What is a HEPA filter?

High-efficiency particulate air (HEPA) filters capture airborne particles from moving air using a dense, random arrangement of fibers. HEPA filters use the physics of particles moving through air to yank them out of the air flow. Their operation is simple but extremely effective, and HEPA filters are now standard issue for almost every air purifier on the market.

But it wasn’t always that way.

Air purifiers have been around for well over a century. The first air purification systems appeared in the 1850s in charcoal-based masks used by coal miners. They were designed to keep toxic dust out of their lungs. The technology was so successful that, less than twenty years later, respirators were added to these types of masks to protect firefighters from breathing in smoke chemicals and pollutants (1).

Beginning in the 1940s, the United States Atomic Energy Commission started experimenting with high-efficiency particulate arrestance, better known now as HEPA, as a method of shielding soldiers from atomic radiation on World War II battlefields (2).

HEPA filters did nothing to filter radiation particles, but researchers quickly learned that HEPA filters could filter out many harmful pollutants.

In 1963, Manfred and Klaus Hammes, the founders of IQAir, introduced the world’s first residential air filter based on HEPA technology, helping reduce indoor pollution as well as chronic asthma symptoms. Not long after, HEPA became so widespread that the U.S. Department of Energy (DOE) required that all filters sold under the name “HEPA” must filter at least 99.97% of airborne particles down to 0.3 microns (3).

Since then, HEPA air purification has become the standard for the air purification industry. HEPA is now thrown around as a generic term for air filters, but HEPA filters continue to filter 99.97% of particles down to 0.3 microns.

The HyperHEPA filter builds upon the HEPA model to create even more efficient filtration systems.

Many manufacturers, including IQAir, have built upon the HEPA model to create even more efficient filtration systems. IQAir’s patented HyperHEPAfilter is one such filter. HyperHEPA filters remove 99.5% of particles down to 0.003 microns, which are 100 times smaller than the DOE’s required 0.3-micron particle size.

2. Not all air purifier designs are created equal.

All air purifier manufacturers know that their filters need to live up to this HEPA standard. But long-standing, strict guidelines around air filters can provide a false sense of security in HEPA.

To advertise an air purifier as HEPA, it only needs to contain HEPA paper, the paper used to construct a HEPA filter. Whether the air purifier’s Total System Efficiency meets HEPA requirements is another story. In fact, most HEPA air purifiers are not tested for total efficiency (4).

The hidden factor at work here is leakage. Despite the high efficiency of many HEPA filters, the housing designs of many air purifiers are not airtight. This means that dirty, unfiltered air passes around the HEPA filter through tiny openings, cracks, and space around the frame of the HEPA filter itself or between the frame and the purifier housing (5).

So even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, they’re only telling part of the story. In some cases, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less (6).

Even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less.

Some air purifier manufacturers have resolved this issue with designs that are built to minimize or eliminate leakage. IQAir uses patented 3D UltraSeal knife-edge-in-groove sealing between the filter frame and the purifier housing to guarantee the full efficiency of our HyperHEPA filtration media.

3. Concerned about gas and odors? Go beyond HEPA.

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).

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.

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.

Learn more.","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.2The average, nightstand-sized Himalayan salt lamp generates only a small number of negative ions into the air, so you may not notice any tangible change in your air quality or health, at least immediately. 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: Stratospheric 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. Tropospheric ozone: Also called ground-level ozone or smog, ground-level ozone tends to develop when heat from sunlight reacts with chemicals near the ground, many of which are produced by emissions from vehicle exhaust and factory smoke. Negative ionization can generate tropospheric ozone indoors. While stratospheric ozone has no interaction with us in the lower atmosphere, ground-level ozone is far more harmful when it builds up to high levels. 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 Fever3,4 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. First used in Eastern Europe, speleotherapy consists of spending time in a salt cave, where four environmental conditions are thought to help reduce symptoms of respiratory illness:5 Stable air temperature Moderate to high humidity Presence of aerosol elements, such as sodium, potassium, and magnesium Lack of airborne pollutants Halotherapy takes the notion that salt cave environments are good for respiratory health by having people inhale small amounts of salt particles that are released into the ambient air of a controlled room to “reproduce” a salt cave’s microclimate. But there’s no conclusive evidence that either speleotherapy or halotherapy actually relieve respiratory symptoms.6Take the claims with a grain of...well, saltSo here’s the takeaway: We’re not saying you shouldn’t get a Himalayan salt lamp. Their dim glow can be quite soothing at night when you’re trying to fall asleep.But they don’t purify air. And “air purifiers” that emits ions and ozone may make your indoor air quality worse, introduce new health problems, and exacerbate existing ones.You can take many precautions to monitorand keep your indoor air clean, but buying a salt lamp isn’t one of them. Try these proven methods instead: Be aware of your indoor air quality. The AirVisual Series consists of portable air quality monitors that use cutting-edge laser technology to give you real-time measurements of key pollutants, including particulate matter. AirVisual Series also provides 72-hour historical and forecast data so that you can know exactly when and why your indoor air quality changes. Control sources of poor indoor air quality. If you’re thinking about buying a salt lamp to purify your air, chances are that you do have air quality issues that you may be able to do something about. The first step to improving your indoor indoor air quality is source control.This means eliminating individual sources of pollution or reducing their emissions. Regularly clean your HVAC system ducts. Install a whole-house air purifier into your HVAC system to reduce indoor pollutants by up to 95%. Replace water-damaged areas of your home to prevent mold and dust mites. Keep paints, solvents, and other chemicals in well-ventilated areas. Ventilate your home. Let in fresh air regularly to lower the concentrations of indoor air pollutants. This is especially important if you live in an airtight, energy-efficient home in which indoor pollutants have nowhere to go and thus build up to dangerous levels. Open doors and windows when outdoor air quality is good. Use a range hood for your stove to capture gases and volatile organic compounds (VOCs) from cooking. Use an air purifier with HyperHEPA technology.

Himalayan salt lamps DO NOT purify indoor air.

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

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. First used in Eastern Europe, speleotherapy consists of spending time in a salt cave, where four environmental conditions are thought to help reduce symptoms of respiratory illness:⁵

Stable air temperature
Moderate to high humidity
Presence of aerosol elements, such as sodium, potassium, and magnesium
Lack of airborne pollutants

Halotherapy takes the notion that salt cave environments are good for respiratory health by having people inhale small amounts of salt particles that are released into the ambient air of a controlled room to “reproduce” a salt cave’s microclimate. But there’s no conclusive evidence that either speleotherapy or halotherapy actually relieve respiratory symptoms.⁶

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

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

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

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

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

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

esters

These harmful chemicals can cause health problems, such as:

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

Cored wicks

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

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.

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

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

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

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

Mission built on compassion Mellissa’s journey to creating Tiny but Mighty began with heartbreak. As a volunteer at her local animal shelter, she learned of the euthanasia of kittens deemed too young to care for. Unwilling to accept this outcome, she founded her own kitten-focused rescue in 2017. “I had so many dreams about saving these kittens. Something told me to just do it myself—start my own rescue.” “I had so many dreams about saving these kittens.

Despite her meticulous cleaning habits, Mellissa found air quality to be a problem. “The dust is crazy. The kittens will go in their litter box and sneeze.” There would still be dust, odors, and allergens in the space “even though I use 99% dust-free litter.” Mellissa explained. “It’s great compared to some I’ve tried, but the dust is crazy. The kittens will go in their litter box and make little sneezes.” This poor air quality not only affected visitors but also had potential health implications for the kittens and Mellissa herself. Dust mites, microscopic creatures that feed on animal’s dead skin, can cause year-round allergic reactions in both cats and humans, including sneezing, runny and itchy noses, watery eyes, and even rashes. Components of pet dander can also act as an allergen, triggering similar reactions. Determined to find a solution to her dust problem, she began her search for an air purifier that could meet the rescue’s unique needs. Life changing air cleaning solution Determined to tackle the persistent dust and allergens, Mellissa sought an air purifier that could truly meet the unique demands of her rescue. After years of frustration with a previous model, she knew she needed a solution that could handle constant activity, fine dust particles, and odors effectively. Mellissa recalled, “The dust was still spreading throughout the house, and I thought, ‘this is just not enough.’” That’s when Mellissa’s father suggested looking into IQAir’s HealthPro Plus XE. Intrigued by its reputation for advanced filtration capabilities, Mellissa decided to give it a try—and the results were immediate and noticeable. The HealthPro Plus XE is equipped with HyperHEPA filtration, capable of capturing particles as small as 0.003 microns—100 times smaller than most air purifiers can filter. This efficiency, proven to remove particles far smaller than bacteria or viruses, combined with gas-phase filtration to eliminate odors, made it an ideal solution for the rescue’s air quality challenges. “The kittens aren’t sneezing anymore. The air purifier has had a huge impact,” Mellissa shared. The HealthPro Plus XE at work next to Leia the cat.

The air purifier has had a huge impact.” When it comes to daily use, Mellissa has found a setup that works perfectly for the rescue’s needs. During cleaning, she runs the fan at its highest setting, ensuring dust and particles are quickly filtered out. For everyday operation, she adjusts the fan to levels 2 or 3, which run quietly enough not to disturb the kittens at night. Looking ahead For Mellissa, clean air ensures a brighter future for Tiny but Mighty Kitten Rescue. She intends to continue providing even more kittens with a safe haven before transitioning to loving homes. The cleaner air and lack of odor in the rescue has already improved adoption visits, a critical step in finding forever homes for the kittens. Mellissa emphasizes her desire to address the root cause of ownerless kittens—unspayed and neutered animals in the population. She hopes to get the word out to more pet owners about the crucial role of spaying and neutering their animals. As she warns, “the cat overpopulation is so crazy here. Spay and neuter your cats, spay and neuter your dogs to help lower those populations.” Conclusion Tiny but Mighty Kitten Rescue’s story underscores the profound difference clean air technology can make in transforming lives—both human and animal. For Mellissa, investing in air purification wasn’t just about solving a nuisance; it was about creating a healthier, more inviting space where kittens could thrive and visitors could feel comfortable.
