It’s interesting in that the report found that disinfection did not reduce the filtration performance of the mask but caused issues with the fit.
So while 3M rightfully cannot recommend doing it it does seem possible. My method of alcohol dip seems not to cause any adverse effects physically. The mask dries out quite quickly and the straps and seal still fit tight.
Again I would not advocate this method under normal circumstances but I have no other way to protect myself right now.
Any mask is better than no mask just like any gun is better than no gun.
If you have the luxury of multiple masks you can always use them in rotation because the virus only lives for a period of time (three days on plastic, etc.). For example if you had seven masks and wore one each day then you would not wear the first one again until it had sat for seven days which is probably long enough to kill any virus.
BTW if it helps CDC found potentially viable coronavirus in cruise cabins 17 days after those cabins were vacated and prior to disinfection on the diamond princess cruise ship. Unknown if any of it WAS viable mind you. But absolutely under the right conditions it can be.
What destroys it is desiccation or denaturing with chlorine/alcohol/heat/UV. The lower the temperature and the higher the humidity, the longer it takes to desiccate. So in a moist cool area, it can last a long time.
Freezing will preserve it mind you. So anything going in a freezer or fridge really should be sprayed down with a bleach and water mix because the virus can survive days to years in those conditions.
This wasn't quite true about the viable coronavirus lasting 17 days. It was a Japanese scientist, not anyone from the cdc, and I believe all he claimed was that he detected it, not that it was viable.
There was a link to the report in the wuhan thread.
I discovered this article today. 2016 Study by Duke University Using Vaporized Hydrogen Peroxide to sterilize N95 Masks and is now beginning to use the procedure at all three of it's hospitals to help combat the shortages of masks.
This looks promising and backed by a repitable medical organization. Here is the Link to the Article

I don't see the testing to ensure that they have not changed the filter media. And that it still performs to the N95 level.
Medical people are NOT experts on respiratory protection.
The Laws of Physics must cease to exist in your world. Is that "magic steam"?
Steam can be hotter than 100C. When it gets above that temp, it's known as superheated steam.
Ok I agree I couldn’t find any documented test reporting either. This situation just sucks. I’m trying hard to keep my guys safe but there are no good solutions. We just cannot get masks. I’ve been wearing the same one for 7 days as of today.
Do you have ANY ideas?
There is some stuff coming out about hydrogen peroxide vapor disinfection without affecting the filtering.
Duke University did some testing of disinfection and then tested the affect on the filtering to meet N95 standards.
That’s the link I posted above were you able to find evidence of testing the effectiveness yet?
This was some work out of Duke University. And they presented in a professional association webinar. They did the testing to N95 standards after treatment.
The problem is, large size hydrogen peroxide generators are not common. Very small ones are available in many hospitals, but this is a not a quick technique.
Also, this would ONLY apply to the specific respirators that they tested.
