See my post Temperature sterilization.

I am doubtful of penetration by ozone and UVC. I could be wrong. I would want to inactivate the virus in all layers of the mask without causing damage. Heat treatment at 65C is probably best. Cooler than a car in Phoenix during summer. IMHO.

The nCONVID19 (I put n in front on purpose) is novel. We will know more in days and weeks to come. I am going with literature on SARS and MERS. I am confident this is the best we have to go with.

Thanks. My oven has a warm. setting, I’ll have to see if I can find the booklet to see what that is. I know it has to be above 140 F. I was afraid that heat would destroy the mask.

I also have a small UV light that I bought and use in a box for my hairbrush and combs. I don’t suppose that would work either.

We probably won’t even need the masks we have, but I’m one who likes to know what to do in case push comes to shove.

Thanks again.
