[Lex Computer & Tech Group/LCTG] ReN95 Respirator Cleaning and Reuse Methods Proposed by the Inventor of the N95 Mask Material Pascal S.C. Juang, MD and Peter Tsai, PhD

[Robert Primak]

 Actually, it's more like three days max. That's because of accumulated dirt, germs, moisture, etc. N95 masks cannot be cleaned safely and should never be washed and reused. They also fail to protect when they've gotten wet, outside or inside. 
Washing and reuse may have contributed to health care workers getting sick with COVID-19 when the masks were in short supply. Omicron COVID makes safe mask use even more important.  With good N95 masks being available at home improvement stores for about $2.00 per mask, packs of 10, limit two packs per visit, I see no reason to push the limits of safe reuse. N95 masks are a consumable personal hygiene commodity. Not a re-wearable clothing accessory. 
I place my limit at three days, regardless of how many hours I've used the mask. After that time, they get pretty gross on the inside. This includes about 90 mins per day of significant exercise, or physical volunteer work for about two to three hours per day. Only about a day in summertime hot, humid weather, or if rain or snow have gotten onto the outside of the mask. Dusty environments can use up an N95 mask even quicker. 
All of this said, N95 masks are about the only protection we can have against the unmasked people who put the "gross" into grocery shopping. I for one am not "done with COVID" yet.

 I was advised by a State health official, who works in the Baker administration, that you can use your N95 mask for 40 hours and then you should toss it away. Never wash it.Derek

Found in a Comment on a Washington Post article (link below).  I haven’t had time to think about the practicality of the method, but am passing this along FYI.
