Description
All StyleSEAL filters are tested at Nelson Labs, Salt Lake City, USA in compliance with US-FDA regulations 21 CFR Parts 210, 211 and 280 at a particle size down to 0.3 microns. Filters up to 99% PM2.5.
We recommend you change filters every 2 weeks. Also change them if they get wet, look very dirty or are hard to breathe through.
Use the Air Quality Index (AQI) to choose your filter
- Use the AirVisual app or the WAQI website to check the 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 90-ORANGE or 90+CARBON filter.
