Exactly as described. These are not like the "cloth masks" that are everywhere now, or even the blue (surgical) masks. N95 masks are SERIOUS medical equipment. (I'm an RN, and several years ago we actually had to be fitted to determine what size we should use) These KN95 masks are made (usually) in China, not always to the standards the USA has for N95. But they seem to be good quality to me. Nope, they aren't very comfortable.... Aren't designed to be, they are designed to minimize expiration and inspiration (breathing out and in) of tiny particles like viruses. As of 12/22/2021, the CDC is advising that we should be wearing a cloth mask AND a high rated particulate mask (like an N95) over the top of that, to truly help allow down this murderous pandemic. N95 masks made in the USA are only available to front line health care workers (when they can get them). These are absolutely better than nothing, much better than cloth or blue masks, and in combination with one of those are a great option. (Arrived quickly, 2 packs of 5)
