The air pollution mask should sufficiently cover the mouth and nose. It is essential that the mask correctly fits your face, in order to prevent polluted air from leaking into the mask.

Make sure you have the right size, either by trying on the mask at a local dealer or looking at the size chart before you order. Adjust the ear straps and nose piece so that the mask seals snugly around your mouth and nose.

Below you can see our founder (on the left) demonstrate the correct mask fit to a customer.

To select the right filters, simply look at the Air Quality Index (AQI) in your area and choose filters with the same color. For example, if the AQI is red, you need the red filters. An easy way to keep track of the air quality is to use an app like AirVisual.

Be aware that higher filter levels are a bit harder to breathe through. If the air quality is unhealthy (AQI is red) you can choose the higher filters. But, if the air quality is moderate (AQI is yellow), you can choose a lower filter to improve breathability and comfort.

The yellow and orange filters also comes in a version with active carbon. We recommend you use carbon filters if you live in the city. While they do filter a little less particles, the extra carbon protect you from toxic gasses, such as traffic exhaust fumes and ozone.

  • After 20 hours of use.
  • If the filters look very gray or dirty.
  • If the filters become wet.
  • If breathing becomes difficult.
  • When the filters are more than 2 weeks old.

As the filters get clogged with pollution they become harder to breathe through and should be changed. You can usually see this, as the filters become increasingly grey. Fresh filters are easier to breathe through and provide higher protection.

Even though a filter may look clean, water can condense in the filter and can result in the growth of bacteria or mold. Thicker filters last longer so keep that in mind when choosing your filter.

The cost of our filters is very affordable and we recommend changing them frequently.

Changing filters in your StyleSEAL Air Mask is very simple and takes only a few seconds. Take a look at the video below to see how easy it is!

All StyleSEAL filters are independently tested and verified at Nelson Labs, Salt Lake City, USA in compliance with US-FDA regulations 21 CFR Parts 210, 211 and 280 at a particle size down to 0.3 microns. Tests show up to 99% filtration of PM2.5.

See our lab test results here.

Activated carbon is carbon that has been treated with oxygen; this causes millions of tiny pores to open up on the carbon’s surface. Once carbon has been activated, it can absorb and remove many chemicals from the air, including the main gas-based pollutants:

  • Ozone (O3)
  • Carbon monoxide (CO)
  • Sulfur dioxide (SO2)
  • Nitrogen dioxide (NO2)

Ordinary particle filters without carbon cannot absorb gasses. On the other hand, carbon cannot filter particle pollution (PM2.5). This is why a combination of particle and carbon filters work best, such as the StyleSEAL 80+CARBON and 90+CARBON filters.

Carbon filters are especially useful in city environments, where there are a lot of traffic exhaust, and other chemical fumes. Carbon filters also help remove smells and odors which can make breathing more pleasant.

  • More Affordable. You only need to replace the filters, not the entire mask. Our replaceable filters also use less material than surgical masks and respirators, which are made entirely from the filter material.
  • Higher Quality Materials. Since our masks are reusable we can use higher quality materials than disposable masks that are thrown away after use.
  • Multiple Filter Levels. You can quickly and easily change filters to match the current pollution level.
  • Easier To Clean. Our masks can be cleaned without worry that the filters will be damaged by the water. Washing filters will reduce their effectiveness and should be avoided.
  • Easily Know When Filters Needs Changing. Since our filters are visible it is easy to know how dirty they are and if they need to be changed.
  • Eco-friendly. Surgical masks and respirators must be thrown away after use, which creates unnecessary waste. Our masks can be reused, and you only have to dispose of the small filter material.
  1. Remove the old filters
  2. Hand wash the mask in soap water
  3. Rinse thoroughly
  4. Hang to dry
  5. Replace with new filters

The Air Quality Index (AQI) in an index used for reporting air quality. It tells you how polluted the air is on a scale from 0-500.

The index is divided into 6 levels, color-coded green to maroon. The higher the pollution level, the more damaging it is to your health.

You can find the real-time AQI for your city or area here, or by using a smartphone app such as AirVisual.

Particle pollution, also called particulate matter or PM, is a mixture of solids and liquid droplets floating in the air. Some particles are released directly from a specific source, while others form in complicated chemical reactions in the atmosphere.

Coarse dust particles (PM10) are 2.5 to 10 micrometers in diameter. Sources include crushing or grinding operations and dust stirred up by vehicles on roads. Particles less than 10 micrometers in diameter are so small that they can get into the lungs, potentially causing serious health problems. Ten micrometers is less than the width of a single human hair.

Fine particles (PM2.5) are 2.5 micrometers in diameter or smaller, and can only be seen with an electron microscope. Fine particles are produced from all types of combustion, including motor vehicles, power plants, residential wood burning, forest fires, agricultural burning, and some industrial processes.

PM2.5 particles are by far the most harmful, as they are small enough to get into the bloodstream, the organs and even the brain, where they cause serious damage. Children are especially vulnerable to the damage caused by air pollution, as their bodies and brains are still developing.

There are many sources of air pollution, but the main ones are: 1) vehicle emissions, 2) power plants, 3) industry and agriculture, 4) chemical manufacturing, 5) heating and cooking with wood or coal, 6) natural sources such as dust, volcanoes and wildfires.

An estimated 92 percent of the world’s population live in areas with dangerous levels of air pollution and, even at seemingly imperceptible levels, air pollution can increase one’s risk of cardiovascular and premature death.

Scientist warn that air pollution is now a bigger threat to health than smoking, and according to the latest estimate, 8.8 million people die every year from exposure to air pollution.

Exposure to high levels of air pollution during pregnancy has been linked to miscarriages as well as premature birth, autism spectrum disorder and asthma in children.

Air pollution may damage children’s brain development, and pneumonia, which kills almost 1 million children under the age of 5 every year, is associated with air pollution. Children who breathe in higher levels of pollutants also face a greater risk of short-term respiratory infections and lung damage.

Other conditions associated with high levels of air pollution include emphysema and chronic bronchitis, as well as lung cancer.

Pollutants can affect cardiovascular health by hardening the arteries and increase the risk of heart attack and strokes, and there is even emerging evidence that air pollution may be linked to mental health conditions and degenerative brain diseases such as Alzheimer’s disease, Parkinson’s disease and schizophrenia.

Yes, according to the WHO, air pollution causes cancer. Scientists have known for years that air pollution can lead to lung cancer, but new evidence shows it can also cause other cancers, including breast, liver and pancreatic cancer. A new study found that air pollution even increases the risk of getting mouth cancer.

One study revealed that every time the concentration of PM2.5 rises 10 microgram per cubic meter (µg/m3), the risk of dying from cancer increases by 22%.

But exactly how does air pollution cause cancer? Pollution may cause flaws in the function of DNA repair, changes in the immune response of the body, or inflammation that causes angiogenesis, the development of fresh blood vessels that allow tumors to spread.

Yes, they are. At least three scientific studies have looked at the effectiveness of face masks for protecting against air pollution. One study found that face masks filter between 14% and 96% of PM2.5, depending on the brand and type of mask. The average filtering capability of all the masks was 48%.

Another study revealed that most face masks are effective at filtering pollution, but vary significantly in how much they leak. The leak inside the masks varied between 3% and 68%, again depending on brand and model. The researchers concluded that the most important factor for mask effectiveness is how well the mask fit the face and is able to seal off pollution

A third study compared regular particle filtering masks with masks that included active carbon layers. Results showed that face masks with active carbon are more effective than regular masks at filtering toxic gasses, such as nitrogen and sulfur dioxide.

We might be biased, but here is our list of features to look for when choosing an air pollution mask:

  • Seal. You can have the most effective filter in the world, but it won’t help you if the air goes around the filter. To ensure the best seal, choose an air mask that comes in multiple sizes and includes adjustable nose piece and ear straps. This way you can adjust the mask to fit your unique face shape.
  • Filter. Make sure the filter used in the air mask is effective. There are different standards and certifications, but any filter you choose should filter at least 95% of PM2.5. Look for lab tests on the manufacturer’s website. If you are exposed to gasses or chemicals such as traffic exhaust, choose a filter with active carbon for extra protection.
  • Comfort. A heavy mask that is rough on the face and hard to breathe through won’t be comfortable to wear. When your mask is uncomfortable, you will tend to take it off more often, losing protection. This is even more true when dealing with children, who are often very active. Look for masks that are lightweight, easy to breathe through and includes an exhalation valve that reduces heat buildup.
  • Cost. Single use disposable masks are expensive in the long run. Even reusable masks can turn out to be expensive, if the filters can’t be replaced. For optimal protection, you need clean filters. Washing the filters are not a solution, as the water causes them to lose effectiveness. Instead, spend a little more money on a mask with replaceable filters. While the investment up front is a little more, replacement filters are cheap and affordable in the long run.
  • Design. You’re dressed up and ready to go to work or go out with friends. You don’t want to match your nice clothes with an industrial-looking respirator or medical mask that makes you look like you are ill. Choose a mask that matches your mood or wardrobe. Think of it as an accessory, like a tie. A nice looking mask also makes you look more approachable to strangers.
  • Eco-friendliness. We only get one life and one planet. Throw-away disposable masks are a huge and unnecessary burden on the environment. Think of the planet when you choose a mask. Choose a product that lasts a long time, and with the minimal amount of waste. The best masks can be reused, with only the small filter material being replaced.

StyleSEAL Air Masks has all of these features. Perhaps now you see why we think StyleSEAL is the best air pollution mask on the market!

The filters used in modern air pollution masks are “fibrous” in nature—constructed from flat, nonwoven mats of fine fibers. Fiber diameter, porosity (the ratio of open space to fibers) and filter thickness all play a role in how well a filter collects particles.

resp filtration

In all fibrous filters, three “mechanical” collection mechanisms operate to capture particles: inertial impaction, interception, and diffusion. Inertial impaction and interception are the mechanisms responsible for collecting larger particles, while diffusion is the mechanism responsible for collecting smaller particles.

StyleSEAL filters are constructed from charged fibers, and include an additional mechanism called electrostatic attraction. This mechanism aids in the collection of both larger and smaller particle sizes. It is very important because it enhances particle collection without increasing breathing resistance.

The WHO has published air quality guideline values, which are recommendations for pollution levels that everyone should try to stay below, in order to minimize the risk of disease. The values for particulate matter are listed here. For other pollutants, such as ozone, nitrogen dioxide and sulfur dioxide, please refer to the WHO website.

The guideline values are:

Fine Particulate Matter (PM2.5)

10 μg/m3 annual mean

25 μg/m3 24-hour mean

Coarse Particulate Matter (PM10)

20 μg/m3 annual mean

50 μg/m3 24-hour mean
