Here is a honest question:
surgical masks block particles that are as small as .2 microns
covid 19 particles are .1 microns or smaller.
How effective can surgical masks or homemade masks, really be against this? If this is true, then why are medical people pushing this? Is it a new opiate for the masses?
I think that the covid particles might be .1 micron in singular form but when they clump together with spit, mucous and other yucky stuff they are much larger and that is how masks can filter them.
As far as everyone claiming masks don't work. Well no shit they don't work if they don't seal around your face. But if you use a proper fitting mask made from effective filtering materials then they do work. Those N95 masks are a joke. Look at the gaps between them and the face. I mean duh. Big surprise those don't work.
