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.Our 80S, 90S, 95S & 99S filters include an anti-bacterial Nano-silver coating that kills germs. All our filter protect against particulate matter (PM).
Use the Air Quality Index (AQI) to choose filters:
- Use the AirVisual app or the WAQI website to find the air pollution (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 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 independently tested at Nelson Labs, USA and conforms to the ASTM F2100 standard at a particle size of 0.1 microns.
I haven’t received them yet!
They are high quality as expected.
Having tried many other masks I still find StyleSeal's fit and contour the best fitting and the very best at doing what it should; filtering the pollutants!
Great product to protect you and your family.
