Question re:K/N95 re-use. We need official/authoritative guidance. Use it carefully and let it sit for a few days in a paper bag or a non-airtight box disinfect (don't wash or heat) and keep using it is my unofficial guidance based on this paper. Anyone? https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7724761/ …https://twitter.com/cwarzel/status/1352299319617982465 …

Yeah I think the challenge is that bc the masks aren’t really tested for intermittent use in a non-healthcare setting that can be a grey area. I always lean into - am I still getting a good seal? Is it soiled? Am I touching the front a lot?

That’s pretty much what I’ve been telling people. My experience is that recommending all the other methods have high potential for more damage than good. One remaining question is the effect of losing electrostatic charge. I’d love for official guidance on number of uses/time.
