Bests & Worsts Reviews from Amazon

These are very comfortable and secure fitting, and don't put unpleasant pressure on the bridge of my nose like my previous rigid 3M (#8511) N95 mask did. The foam nose band runs all across the inside top and provides a comfortable, moldable, snug seal that does a better job of keeping my glasses from fogging than my previous mask, except if I exhale with a big sigh through my mouth or nose, but even then, the fogging is slight and dissipates quickly. I wasn’t able to wear my glasses in the correct position with my rigid mask, but don’t have that problem with this mask. Breathing in this one is a little warmer than my previous KN95 and valved #8511, and on warm days I can feel the beginnings of a little bit of sweat above and below my lip , but it's worth it for me to have the full, all-around close fit protection an N95 mask provides that KN95's don't. I like that they fold flat for carrying around. In case this is helpful, I have an average sized head and full face with a square-ish jaw. The mask sits higher on the bridge of my nose than on the guy in the picture--about half inch above the inside corner of my eyes, is 8" (accounting for the “duck bill” expansion) from the top to the bottom of the chin tab and about 6” side to side on the widest part of the chin tab area. A reviewer said the mask smelled like pickle or salt and vinegar chips and I agree, they do smell a bit like that (it’s the foam nose band and not the mask itself), but it didn’t bother me and like the same reviewer said, you don’t notice it after a while. It did NOT smell like burnt rubber mentioned in another review. The middle part is stiff like the rigid N95s, but the top and bottom part are a soft, flexible (kind of reminds me of slightly worn jeans) and what appears to be more breathable fabric. The straps look like long wide, flat rubber bands and appear to be securely stapled--I pulled pretty hard on them at the ends and they didn’t move from under the staples. Since they’re smooth, they slide down my hair if I don’t put them high enough on my head, but they’ re comfortable in that position and I hardly notice them at all. I was looking for something to replace my rigid, valved N95s and I'm happy with these.
