Indeed, though you can reuse them for a while if you just go out for groceries and you wear it for like 20 minutes at a time. I just wash my hands with 70% iso before and after putting it on / removing it (or touching it at all); and any mask that has been used recently has a 48 hours cooldown period before it's used again.
I'm sure, and moisture is a big no-no (I throw them away if there's significant moisture on them, like if I went out and it rains), but all in all a mask made to be worn 8 hours will still work fine if you use it in small increments of time. Also found those recommendations by the CDC that suggest rotating as I described above - and that's for hospital use, apparently. Though they do suggest a 72 hours downtime instead of my 48 hours suggestion.
Replacing N95's frequently is strongly recommended

I believe the N95s also possess a static cling quality that helps prevent particles from passing through that is lost over frequent uses
