Each mask comes with a pocket and one of these inserts made of activated carbon & non-woven melt-blown filter cloth providing a 5-layered filter protection system. This helps keep away air pollution and a range of airborne contaminants.
Test reports are available upon request.
Our masks are washable up to 40 times. You can just take the inserts out and put them in the wash. We recommend you change the inserts every 3-4 uses.
