Comfortable fit, you can feel the filter/gasket when inhaling, reduces the ability to smell when on. I did 5 recommended tests to determine if it is fake or not. The tests included impact test, water leakage test, waterproof test, 5-ply test and fire test. It failed the water leak test, which bothered me, but I checked the KN95 specs and water leaks are not a requirement to pass KN95 certification, so it's not a reliable way to tell if it's one counterfeit. When the mask was cut, there were 5 layers, and the inner layers melted rather than burned, so I'm reasonably sure these are acceptable masks. For those who don't know, N95 and KN95 masks filter 95% of medium-sized particles. is based on static electricity, and unfortunately no home test can determine its effectiveness. The sophisticated tools needed to test this material are simply not available to the average person. While the water leak test failed utterly, the reality is that it doesn't test for static electricity, it tests for water leakage, and there's really no connection between the two. In fact, they are listed as "non-medical", which I believe means they fail the water leak test. Surgical versions of the KN95 must have additional fluid approvals for things like blood spatter and other fluids. In short, I believe they are spot on on their "ingredient list": 42.5% nonwoven, 29% meltblown, and 28.5% hot melt. air cotton. How effective it is for you is up to you.
