I have a UV C sterilizer and it can help along with heat to make an N95 mask partially re-usable. I advised that the masks can provide input protection more than once if carefully treated between uses. Time is the best way to clear the mask, let the mask lie for several days. UV B and UV A can, on long enough exposure, help and temperatures at or near 160 degrees can also help. I have heard that some masks might be able to be sterilized in a microwave. The rules are pretty simple. Cloth or paper masks only. No metals of any kind in the mask. Nothing in the mask that can be destroyed by the microwave, such as a gel or other "liquid" component, and no plastic/rubber parts that might be destroyed. If the mask is simply cloth/paper only, then lay the mask in the microwave next to a mug of water, zap it for 3 minutes and then (in theory anyway) the mask is sterilized. The only variant of this that I have heard of is that (for cloth masks only) you can soak the mask in water first, then lay it on a paper plate before putting it in the microwave with the mug of water a zapping it. I don't know if it really works. EK!!!

I have a Lumin for sanitizing my CPAP equipment. It's been relegated to sanitizing keys, iPhones, glasses, credit cards, cash, and anything else that's portable and possibly contaminated. Any living organism (bacteria, virus, mold, etc.) that goes in pretty much isn't living when it comes out. However, as far as masks, it's an extra step but not necessarily 100% effective because the organism must be exposed to the UV, and the light may not completely or sufficiently penetrate a multiple layer cloth mask. Still, I run a couple of passes on them. It's like chicken soup; I couldn't hurt.
