Filter Packs

PM2.5 Filters:

PM2.5+ Carbon Filters*:

*CARBON FILTERS DO NOT SHIP INTERNATIONALLY DUE TO EXPORT BAN!

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 (80+, 90+, 95+, 99+) provide 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 filter protect against particulate matter (PM).

Use the Air Quality Index (AQI) to choose filters:

1. Use the AirVisual app or the WAQI website to find the air pollution (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 filters 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.
