A properly fitted mask shouldn't leak around the sides. The PFF2 (my country's equivalent of N95) mask I use doesn't leak anywhere when properly adjusted. (Like the sibling comment, it's a 3M, either the 9320+BR or the 9360H; see https://www.3m.com.br/3M/pt_BR/p/d/v000465595/ for its page complete with usage instructions.)

> A properly fitted mask

This is exactly why masking isn't as effective as it should be _in aggregate_. N95s aren't foolproof to use even for people who are trying to use them properly, then you have to add in the folks who pull their mask down to cough or to talk.

My favorite was the chin diaper. Particularly because the state I live in (idaho) never really had strict masking requirements so it really never made any sense.

I still occasionally see adults out in public wearing the chin diaper, or with the mask partially or mostly covering the mouth but not the nose at all.

I just don't get it. Why bother? Public outdoor masking rates even here (San Francisco) are anecdotally well under 10%. Why waste the time and effort (and in some places, social consequences) to do something like that completely ineffectively, when nearly no one else is bothering at all?
