So, it does have to be a mask that will actually protect you.
If you didn’t pay, a pretty steep price at the time, for the right mask (like something that will protectv you from paint fumes) then you were wasting your time.
Source: When I mask up I use N95’s. I use best judgement, haven’t gotten covid. Not too late to protect yourself. I don’t think I’ll be able to keep it up forever, but I’m banking on new vaccines kicking covids ass.
