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).
Use the Air Quality Index (AQI) to find the filter level you need:
- Use the AirVisual app or the WAQI website to find the air pollution level (AQI) in your area.
- 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.
- Higher filter levels are harder to breathe through and also more expensive, so don’t choose a higher level than you need.
All filters are independently tested at Nelson Labs, USA and conforms to the ASTM F2100 standard at a particle size of 0.1 microns.
