Replaceable PM2.5 & Carbon Filter Technology
All STYLESEAL filters are independently tested at Nelson Labs, and conforms to the ASTM F2100 standard at a particle size of 0.1 microns. See the filter test reports here.
They filter up to 99% of particulate matter (PM), depending on which filter strength you choose. See more below.
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
STYLESEAL filter comes in different strengths to match the level of pollution in your area. The filters have rings that are color-coded to match the Air Quality Index (AQI). Simply choose filters that match the pollution level in your area. For example, if the AQI is orange where you are, use orange filters in your mask.
Even the lower level filters still provide you with plenty of protection. All filters protect you against particulate matter (PM) air pollution. The higher filter levels are more efficient, but also harder to breathe through, so don’t use a higher level than necessary.
You can see the difference in protection between the filters in the table below.
Carbon Filters Absorb Gasses
In addition to filtering particulate matter (PM), our carbon filters use activated carbon to remove gas-based pollutants from the air. Carbon can absorb a very high amount of pollutants in gas form.
The STYLESEAL 80+, 90+, 95+ and 99+ filters all contain active carbon. If you are in heavy traffic or work with chemicals we recommend you use carbon filters.
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.
Nano-Silver Filters Can Kill Germs
STYLESEAL 80S, 90S, 95S and 99S filters all include a medical grade Nano-silver coating that eliminates bacteria and viruses. Nano-silver can transform protein expression and generate reactive oxygen species (ROS) that damages the DNA of germs and kills them.
Of course they also protect you from air pollution in the form of particulate matter (PM).
How can I know the Air Quality Index (AQI) in my area?
We recommend you use the AirVisual app to keep track of the air quality in your area. You can install this app on your smartphone to keep you updated on the AQI in your area or city. You can see the AQI levels below:
