re: Corona Mask

Small update. One of the household items that tested extremely well was a vacuum cleaner bag. I put one to my face and tried to breath through it but it didn’t work, so I discarded the idea. HOWEVER – a friend of mine used a vacuum bag for the filter medium. I guess most vacuum bags are actually 2 bags in one. The inside is a liner and the outside more durable. The liner is what you want. I just cut one open and the liner from one bag looks to be good for about 20 masks (20 uses since its the disposable part).
