Has anyone seen anything on whether it is possible to disinfect a N95 mask and re-use it?

Yes. 65C for 15 minutes. The masks can be reused, however will become harder to breath out of due to particulate clogging. The temperature and time is based on MERs studies.

If you have an electric oven you can set it to that temperature. A spa sterilizer can do the same. The prices have gone up.

I'm not comfortable with strictly UVC sterilizers because of depth of treatment.

Best.

Noted & thanks. Good info.

We have an Oster electronic control toaster oven with a convection setting (tends to even out the temperatures inside). And I can monitor with a temperature gun on the first tries.

My Mom’s oven I’ll avoid. It chars the side of the pizza in the back of the oven before the front is done.

Noted on the clogging. I kinda figured that. Since we have only 5 of the N95’s, I may try “prefiltering” with something over the N95 mask to take out dust & such. A bandana should do it. Hopefully WalMart doesn’t think I’m a bank robber gone lower-end-intended-target.

Mom’s place is fairly “low dust”, but even so, it is always interesting to shine a tight beam high intensity light in the dark, almost anywhere, and see all the “stuff” floating around.
