Just my 2 cents here on masks. I spent the better part of 2021/2022 wearing KN95s. I wear glasses and it became very apparent to me that the KN95 was not providing good coverage. Sure, when you breath in it "sucks in" and seems like it is (I think there's a term for that), but based on how much my glasses were fogging, even with a nose piece, I was suspect. If I didn't wear glasses, I'd have no clue. When I flew out from east to west coast, I finally got off my cheap side and bought a 3M Aura N95 mask. To be honest, I do *not* like the head straps versus ear loops, but damn, that mask fits well and is way more comfortable that any brand of KN95s I had. My glasses *never* fog which tells me I have a good seal, and it's got great breathability.
If anyone is truly concerned about having to wear one a long time and be comfortable, I'd highly recommend these. Again the head straps, which are like wide rubber bands, aren't my favorite. There is a higher level model that has more comfortable head straps though.
