problem is that we can’t create masks that will filter out particles less than .3 nano something or other (nanoparticles? I dunno0 but it was .3)- if we got material to do that it would be hard to breath and uncomfortable ot wear-
However, i do feel that some, maybe most, will get stuck on the fabric, and not make it to the face- bit i dunno- maybe they all just slip right through-
If so- then even sick folks wearing them won’t do any good to prevent other from getting it i woudl htink-
