Paper coffee filter
2 small key rings
To reiterate what’s coming from the authorities: we should consider that we may be infected and not know it. Makeshift face coverings do help to contain infectious micro-droplets from flying all over the place when you exhale, but don’t do as much as far as filtering out airborne particles when you breathe in.
Many examples already exist for doing face coverings with at-hand materials. Mine uses one of those big wide wire-ties that come on coffee bags to create a stiff bendable ridge across the top of the mask to snug it up across the bridge of your nose. Bandana material does not do so well as a filter, so I added a paper coffee filter into the fold. Vaccuum cleaner bag material would be good as well.
