Moshi Nanohedron Filter Replacement - Large/Medium

Moshi's Nanohedron filters are specially designed for Moshi OmniGuard reuseable face masks. Blocking out particles down to PM 0.075 (75 nanometers), these filters protect against bacteria, viruses, pollen, dust, smoke, pollution, and more. Featuring Moshi's proprietary five-layer design, Nanohedron filters have been tested to 99.9% Bacterial Filtration Efficiency (BFE) and Virus Filtration Efficiency (VFE), offering 99.9% protection against the most commonly-found airborne contaminants. With a lifespan of up to six weeks (depending on environmental conditions), the filters can be sanitized using a 70-75% alcohol spray without affecting performance.
