i did a whole thing once on masks and there ability to filter. the only thing that comes close to straight filtration for everyday person is a HEPA filter. Then you'll need a proper seal, its pretty sad to see someone wearing a mask with a beard. And anyone with glasses will tell you the seal is shit too.
and I guess the eyes, ears, under fingernails, and cuts... dont worry about that, just wash your hands dawg
ad to see someone wearing a mask with a beard
I have a full beard.... No mask ever fit well.
well, you cant have beards working in a refinery, a cop, firefighter, military because of it
Time for Hitler stash?
