How large is a virus the mask is supposed to defend against? How large are the openings between the fibers of the material used to make the mash? the mask would help keep a guy from sticking a finger up his nose, but stop a virus?
I get a kick out of the idiots and morons on tv that talk about anti-bacterials when they are talking about dealing with a virus. A bacterium is very small but any virus is way way smaller.
