How far does the air project from the user after it goes through that filter? And why the fuck do cartoonists have to ask these questions?https://twitter.com/MayoClinicHS/status/1259241740269170689 …

Wow - I was wrong I guess. These masks are actually like 1 way mirrors. Filtered air comes in the mask but those same entry holes don’t allow air back through BUT there’s different holes that only allow exhaled (non filtered) through. It really is a 1 way mask! Crazy.

You just discovered what "valve" means in an N95 mask. Yes, the N95 mask is a one-way filter by design. You have not cleverly discovered an incongruity.

that's what I've seen, that faux masks are ostensibly to serve as a liquid barrier to prevent liquid from the wearer's mouth and nose from reaching another person's face or mask. The small size of the passages in an exhalation valve should in theory prevent free flow of liquid.
