Our Filters

All StyleSEAL filters are independently tested at Nelson Labs, Salt Lake City, UT, USA in compliance with US-FDA regulations 21 CFR Parts 210, 211 and 280 at a particle size of 0.3 microns.

StyleSEAL filters are replaceable, which has many advantages:

  • Costs less in the long term
  • You can change filter strength
  • No risk of damaging the filters when you wash your mask
  • Easy to know when it’s time to change the filter
  • Environmentally friendly

Our Filter Levels

StyleSEAL offers filter levels that match your level of pollution. The filters have a ring colored to match the Air Quality Index (AQI).  The higher filter levels are thicker and more efficient, but also harder to breathe through.

Use filters that match your level of pollution. For example, if the AQI is orange, use orange filters in your mask.

Lower level filters still provide you with plenty of protection. The difference in protection between the filter levels is only 5%.

Active Carbon Filters

This method of filtering uses activated carbon to remove pollutants from the air. Carbon has a very large surface area, allowing it to absorb a high amount of pollutants. The 80+, 90+, 95+ and 99+ filters contain active carbon. The major gas pollutants include:

  • Sulfur dioxide (SO2)
  • Carbon monoxide (CO)
  • Nitrogen oxides (NOx)
  • Ozone (O3)
  • VOCs – Volatile Organic Compounds

The primary source of gases is the burning of fossil fuels in power plants, industrial processes, and motor vehicles. These pollutants, in their gas form, cause harm to our health and the environment. If you are near car exhaust or work with chemicals (e.g. nail/hairstylist) you should use carbon filters.

Nano-Silver Filters Can Kill Germs

Nano-silver can transform protein expression and generate reactive oxygen species (ROS). This damages the DNA of germs and kills them. Nano-silver can kill a wide range of germs. The 80S, 95S and 99S filters all include a medical grade nano-silver coating that helps eliminate airborne bacteria and viruses.

Easily Changeable

Our filters are easily installed by attaching the loop side of the filter to the hook side in the air mask, as shown below:

How do I find the Air Quality Index for my city?

On the World’s Air Pollution website, you can find the Air Quality Index (AQI) for every city in the world. Another tool we recommend is the AirVisual air quality app. You can install this app on our smartphone to keep track of the AQI readings in your area or city.
