KN FLAX [40Packs] KF94 - Face Protective Mask for Adult (Black) [Made in Korea] [40 Individually Packaged] Premium KF94 Certified Face Safety Black Dust Mask for Adult [English Packing]

Amazing masks. They're light and breathable. Very good quality. Masks are very comfortable, they're perfectly fitting the face and I'm very confident that they'll provide the best protection against viruses and bacteria. I'm happy that I found them. Thank you!

I am not sure if these masks are approved by the U.S. regulators pass as acceptable but I sense that they are good masks. Do Your Own Research. I like these masks because they fit, they stay on and in place, they do not gap at the side of your face and last they are breathable and comfortable. (Note: I do have trouble with glasses fogging but I do with all masks.) These are more breathable than the masks I have personally made with three layer cotton (one layer 675 TC). If we went back to very high risk situation, I would use these and double with one of my home made masks.

I recently fell in love with these types of masks. The %1 difference is perfectly fine, since I'm vaccinated and a shut-in. Lol This brand of mask is great; highly recommend. I would be wary of the sizes though. I was wearing some that fit great and didn't fog my glasses, but these feel a bit small and fog my glasses almost as bad as the surgical masks. I am convinced it's the fit, so maybe I went a size too small, which was "large". My head isn't even that big, so now I have a complex. Anyway, even though I may have the wrong size, the masks are super comfortable. The straps don't hurt even after wearing them for 8 hours at work. All in all, pretty good masks. 👍 The only reason I gave 4 stars is that the sizes seem off and it doesn't do anything for the fog, when other less-expensive brands seem to do that pretty well.

This is my fourth purchase of this mask. We use it when we travel, especially on airplanes during flu season. Works well for our intended use.

These masks are excellent. They feel sturdy and well-made, with a snug fit that stays in place without feeling too tight. The ear loops are comfortable for longer wear, and the KF94 shape gives good coverage while still making it easy to breathe. I also like the black color for a clean, professional look. Great value for a 40-pack and I will definitely repurchase.
