Each of our masks comes with filters for the end-user. After research and testing, we've now started to make them out of sterilization fabric, a material used in the sterilization of surgical instruments. Made out of a type of polypropylene, this fabric is affordable, readily available, and has an impressive ability to block virus particles.
When you receive a Masks of Love mask, insert the filter into the pocket between the layers, center it, and open it up flat. You can reuse the sterilization fabric filter by first disinfecting it with heat: remove it from the mask; put the filter only in a low temperature oven, at 165 degrees; and let it "cook" for 30 minutes. Lay it flat while cooling.
Sewers do not need to provide filters for the masks they make. We add filters to orders when we ship. For now, filters are not available separately in our online mask store. We have supply bundles a Masks of Love HQ if you need them: Flora, 428 Haywood Road; Mondays, Wednesdays, Fridays, 12 p.m. to 2 p.m.
