One pack contains 5 pairs of 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.
Carbon filters provide protection against chemical gasses and car exhaust. We recommend you use carbon filters in areas with heavy traffic.
The 95S-RED and 99S-PURPLE filters include a medical grade nano-silver coating that help eliminate bacteria and viruses.
Use the Air Quality Index (AQI) to choose filters:
- Use the AirVisual app or the WAQI website to check the air pollution (AQI) in your area or city
- Choose a filter that matches the color of the AQI. For example, if the AQI is orange, choose the 90-ORANGE or 90+CARBON filters
- Higher filters are harder to breathe through and also more expensive, so don't choose a higher level than you need
All filters are tested at Nelson Labs, USA in compliance with US-FDA regulations 21 CFR Parts 210, 211 and 280 at a particle size of 0.3 microns. Blocks up to 99% small airborne pollution (PM2.5).
