Function & Filter Replacement

The filter media of the mask is tested and certified for standards that are similar to the American N95 ( GB2626-2006, certification KN95), which means it can filter more than 95% of harmful particles as small as 0.3 microns, such as PM2.5, PM10, pollen, and bacteria.

There are many variables to establishing a precise filter life, such as the pollution in your area. Our filters can last up to 80 hours on average and we suggest changing the filter every second week or so.
