Amazingly generous assortment of masks. My faves were the Respokare N95 (not pleated) and the 3M Auras. Unfortunately, I have allergies but usually not allergies to scent. The smell of the Auras was pleasant but stuffed my nose. They were very comfortable and I might have been able to make the straps work. (I have a problem with head straps. They slide off my head. I've tried the pony tail, but my hair is just a bit too short. I tried bobby pins and that helps a little but I still fiddle.) The hard shell N95s were a non-starter. It's not that they were just tight around my face but the molded body pressed on my nose and even my cheeks sp I couldn't breathe easily.I don't think I have THAT big a nose, since I'm 5'0 and 95 lbs. Probably just the shape of my head and face. The Dobu was just to short too. I didn't get the Moldex black N95 so I have on opinion. But I do like the shape in the photo. I can't be vaccinated, starting with my 1 and only polio shot in elementary school and proved twice with 2 flu shots, decades apart. The first flu laid me out for a year, I caught mono at a group home, and was left with chronic EBV which I managed to live pretty well with until stressors reactivated it. I was being treated for that by a holistic MD, working full time and driving 200 miles round trip every Tuesday to get treatments which were working. He had a special batch of flu vax during the winter of 2013 and his opinion was that I was allergic to the adjuvants and his was adjuvant free. Since he was doing so good with my EBV, I took the shot. Within 2 months I was unemployed and 90% housebound with Myaligic Encephalomyelitis/CFS. I agonized over the mRna but decided against it after seeing feedback from other ME/CFS patients who saw a decline in their baseline health, some going from housebound to bed bound. I'm telling you all this because I didn't even try on the K94s. I have to get the absolute best protection short of the 3M P100 halo with cartridges which I have but find very uncomfortable. I haven't been out in public in 3 years and I need this mask for cardiology workup. So it has to fit well, offer excellent protection, be comfortable and light weight. If I had to pick one, I'd have to choose the RespoKare and gerry rig it to my head somehow because other than the head bands, it fit all my criteria.
