NOTICE: DO NOT MICROWAVE YOUR MASK!
The metal in the nose bridge will catch fire. Instead - gently hand-wash with laundry detergent and water, and hang to dry.

We believe our hand-made masks (when properly used with filters) to be 90-95% effective at protecting against the inhalation of viral bacteria. Here's why:
FACE MASKS: The double-layered cotton or cotton-blend face masks are by themselves around 70% effective (even without a filter inside) at filtering out micron-1 particles (like this SARS virion which causes coronavirus - source).
DISPOSABLE FILTERS: Our disposable filters (sized & carefully hand-cut in highly-disinfected home environments - Made from Blue Shop Towels - and are by themselves 87% effective at filtering out viral particles (source).
Based on the latest research of the most effective "found" materials for filtering out viral particles (see our source here).

Combine the two together (handmade mask and disposable filter inside) - and effectiveness of this 4-layer combination over your mouth and nose likely provides a combined 90-95% protection at filtering out the viral bacteria in the air... and is still nicely "breathable."
Compare this to surgical masks, which are shown to be 97% effective. So handmade masks & filters like ours, when used properly, are an excellent combination of protection - and all using locally found non-medical materials!
