> I have a KN95. I can't get it to fit on the top. Always fogs my glasses. But when I breathe in, I can clearly see by the fabric's motion that air is substantially being pulled through the material rather than around it.
IIRC, KN95s were designed for flatter, asian noses. I think I read somewhere that one of the motivating factors for the design was that it's harder for asians to get a good fit with some types of N95, because they were designed for caucasian noses.
I have a big nose, so KN95s never work for me, unless I retrofit a really long and beefy metal strip for the nose.
