@lookitmychicken oh no! A lot of people have that same misconception, though. Although it sometimes makes sense for them to be single use in, say, a hospital or industrial setting, my understanding is that for everyday usage you can pretty much wear them til there’s not a good fit anymore, or til they get gross.

I wish I remember the source rn, but I recently read that part of the n95 standard is that they are supposed to maintain effectiveness for up to 200 hours of use. Anyone else know more than me? #covidIsNotOver
