I work at chicken processing place it is always cold, lots of kn95 mask are not water proof at work but this mask have/ has not been retained water at all inside mask.Feel very comfort & clean because inside mask is dry after wearing 10 hours.Just order another box.
These masks are excellent quality for KN95 Masks.I am immune compromised and feel a lot more confident wearing these to the doctor versus a cloth mask (one step above useless) or wearing 2 disposable masks. If you are looking for a reasonably priced KN95 mask, this is a great option.As you read the reviews and filter through the good and bad, I want to point out a couple different things. N95 and KN95 masks are different, so don't buy these and expect to get a N95 mask. These masks specifically say they aren't medical masks. I think it's unfair to give this product a lower review due to either of these facts. The product description is very clear.
