you can't get real 3M of course, there's just lots of sketchy sellers claiming their KN95 on on the FDA "acceptable" list which is BS
this is the only 5-ply I've seen that enough people say is not totally fake, the 3-ply aren't serious enough, more layers = more surface area
plus they are not some store that opened last month, I'd only buy from someone who existed before last year
adding: same 5-ply 5-pack mask on amazon for $17
5-layer
just for comparison here is another known seller but their kn95 are only 3-ply

don't buy those IMHO
