> Are they better than no masks?

This is the important question. Well are they? I’ve seen a lot of people wearing N95s and almost every one of them are wearing them incorrectly. Is this better than a cloth mask? I don’t know. But having huge gaps on the bridge of one’s nose where air flows is really bad to reduce risk. And my favorite is seeing them work with beards that prevent a seal.

I can’t find any tests of cloth mask vs bad n95. Saying “common sense” as the reason is not a compelling reason to try to get 300M people doing something.
