Bests & Worsts Reviews from Amazon

I got this product just as everyone else, concerned about the new coronavirus. I had previously bought some kn95 masks that a friend who's a doctor recommended me and he explained to me that proper kn95 masks have 5 layers of protection, the outside layer, the inside that is in contact with your nose and mouth, and three other layers that kinda look like dryer sheets in between. So I received this and from grabbing the first one I could feel how thick and fluffy it felt, so before giving it any outside use I decided to cut the inside and take a look and what's in there. I came to find out that there is only 4 layers. The outside, inside, a layer that feels like some kind of paper and a cotton bed. So from that I can tell this are not proper kn95 masks. Also the ear elastics are not even so you gonna have one side right and the other a bit loosen, the mask feels small and really easy to breath with. Finally the outside and inside layer seem to be of a less finer material than the ones I previously bought. I wouldn't recommend this to anyone for wear in outside crowds. I don't want to throw them away so I guess I'm gonna use them to clean around the house. But by no means gonna take one of this out with me to a grocery shop or other places, unless it is the last resource. I hope you can see some of the details I previously mentioned on the pictures attached (compared this to the ones I already had, unfortunately I wasn't gonna cut the inside of my other masks) and make a decision for yourself. In my personal opinion this are not worth 30 bucks for the 10 pack, maybe 20 as much and that's even a bit high.
