PM2.5 Air Mask Filters:

80S-YELLOW (moderate pollution)
90S-ORANGE (high pollution)
95S-RED (severe pollution)
99S-PURPLE (hazardous pollution)

PM2.5+ Carbon Air Mask Filters:


One pack contains 5 pairs of air mask filters. We recommend you change filters every 2 weeks. Also change them if they get wet, look very dirty or are hard to breathe through.

The active carbon filters (80+, 90+, 95+, 99+) offer protection against chemicals, gasses and car exhaust. We recommend you use carbon filters in areas with heavy traffic.

Our 80S, 90S, 95S and 99S filters include a medical-grade nano-silver coating that kills bacteria and viruses. All our filters protect you against particulate matter (PM).

styleseal air mask filter levels

Use the Air Quality Index (AQI) to find the filter level you need:

  1. Use the AirVisual app or the WAQI website to find the air pollution level (AQI) in your area.
  2. Choose a filter that matches the color of the AQI. For example, if the AQI is orange, choose the 90S-ORANGE or 90+CARBON filters.
  3. Higher filter levels are harder to breathe through and also more expensive, so don’t choose a higher level than you need.

EPA air quality index aqi

All filters are independently tested at Nelson Labs, USA and conform to the ASTM F2100 standard at a particle size of 0.1 microns.
