Review on HIWUP KN95 Face Mask - 50Pcs White Individually 💯 Packaged Disposable Masks, 5-Ply with ≥95% Filter Efficiency for PM2 Protection by Timothy Weems

I thought they were great. NO! The strap broke on the first use. He punched a hole where it came out, threaded a rubber band through the hole, and tied a knot in the rescue mask. Then it broke on the other side. The same thing happened with the second mask and my wife's mask did the same. I then used the mask in a dusty environment which exposed any mask leaks. It was a lot dirtier on the inside than the outside, especially around the nose because I couldn't adjust the built in strip to the bridge of my nose because it kept bouncing. I have never experienced this problem when using masks with food strips. Very disappointing! If this mask cannot protect me from dust, how will it filter out droplets and aerosols with viruses? This is indeed a set of Maginot masks.
