High-risk people should wear N95 masks. Everyone else should wear cloth masks. High-risk means over 65 or anyone with one or more cormorbidities, save that, if hyper-tension is the only one, it’s not high and they’re under 40, cloth masks are okay.
I order two N99 dusk mask in January that are washable with 38 extra filters. It has the same rating as the N95 just not certified like the medical N95 mask. We were those when we have to go into a grocery store.
N99 and N100 should work great for us who are just walking through a grocery store.
