Unique design allows the use of disposable, KN95 multi-layer filters to deliver a permanent Virus protection solution. Equipped with dual valves, one on each side… inhaling and exhaling provide a natural, uninhibited breathing experience not found in other competing products. Designed for ultimate protection from airborne viruses and microparticles, our respirators provide a complete frontal and side coverage that effectively blocks microparticles from entering your body from your nose or mouth. Even if you have a tendency to touch your face on occasion, our maxi-facial coverage design prevents your fingers from reaching most areas that could potentially provide an entry point for harmful viruses and impurities.
