Someone once told me that the box in which masks came in says “doesn’t protect from viruses”, as if it was hidden-in-plain-sight proof that masks don’t work.
Yeah, they don’t protect the user from viruses, they protect other people. The box is technically correct, Patricia, there is no conspiracy here.

They will, but you have to follow some protocols, like not having beard where the masks is supposed to seal around your face, not using it more than ~3 times (iirc), not trying to clean it (just let it rest for some days on a clean surface) and etc.
Basically always seal testing.
Also, iirc the N stands for not oil resistant, so any oil staining ruins it. I’d guess that includes sneezing on it.
