Review (2/5): n95 mask sterilization: this UV device is a bad idea
BIG PROBLEM !!! The UVC does some kind of damage to plastics resulting in some sulfa-containing byproducts. N95 masks have at least 4 layers and plastic (polypropylene derivative) is a component. At a minimum, the objects ( n95 mask ) stink. I don't know if breathing through the masks afterwards brings toxins to the lungs. On the good side, UV does not penetrate very deeply so it should (in theory) not damage the n95 mask I wish I could return this.
I rate is very high for (1) rapid shipping from china (2) works but low rating fro the purpose I wanted : to sterilize n95 masks.
