idMASK protects you the way other masks don’t. The velvety soft silicone facial seal creates an airtight seal between your face and the sides of the mask, sealing out dangerous micro-particles so you breathe only clean filtered air.Electrostatic filters capture tiny micro-particles such as viruses, bacteria, smog, etc. As air passes through the filter media, an electrostatic charge is created to attract and capture these tiny particles to the weave of the filter. For pollution, it’s recommended to replace the filter after 7 consecutive days. For viruses, change the filter out daily, letting the used filter sit for a few days, then rotating them back in. To clean, wash the silicone seal, polycarbonate frames, and strap with hot soapy water. Never wash the filter—they must be disposed.idMasks are also Buy One, Donate One, so your purchase protects two. In response to the virus, idMASK will be donating disposable masks for medical workers in developing nations.
