42.5% non-woven fabric, 29% meltblown fabric, and 28.5% hot air cotton.
Comfortable fit, can feel the filtration/seal when breathing in, significantly reduces the ability to smell scents when on.
I did the 5 recommended tests to determine if it is counterfeit or not. The tests were the blow test, water leak test, water resistance test, 5 layer test, and burn test. It failed the water leak test which had me worried but I checked the specifications of KN95 and water leak is not a requirement to pass KN95 certification so it's not a foolproof way to tell if it's fake. When I cut the mask open, there were 5 layers and the inside layers melted instead of burned so I'm relatively confident these are acceptable masks.
For those who don't know, the N95 and KN95 masks filters 95% of medium sized particulates based on static electricity, and no at-home test can really determine its effectiveness unfortunately. The sophisticated tools needed to test that stuff is just not available to the average person. While the water leak test failed immediately, the reality of it is that it doesn't test static electricity, it tests if water leaks and there's really no correlation between the two. In fact, these are listed as "non-medical", which I assume would mean that they would fail the water leak test. The surgical versions of KN95 should have additional liquid tolerances for stuff like blood splatters and other fluids.
In short, I believe these are accurate in their "ingredients list" of 42.5% non-woven fabric, 29% meltblown fabric, and 28.5% hot air cotton. Whether that's effective enough for you is for you to decide.
