Update on N95 respirator use/decon. just posted on another thread, but thought the folks who come here for useful info, might find this, well, useful. First off, if I had a public-facing job, I'd do whatever I could to find and wear an N95 respirator, which actually filters out most virus droplets/particles, as opposed to surgical masks which do little of that (they'll protect against larger droplets only). I still think all employees that are exposed to the public should have N95 respirators (we're using them for high contact essential jobs where I work).
With regard to decon/reuse, if one had 3 or 4, they could be rotated each day, such that every time one is used it would have sat for >72 hours (beyond which virus viability has not been seen to date), which should be safe. Alternatively, heating in an oven at 140F (70C) for 30 minutes will destroy any viruses, with what appears to be minimal impact to the filtration capability, although that hasn't been evaluated beyond a few cycles. Vapor phase H2O2 (hydrogen peroxide) works best, but not many people have that at home, lol. And UV can work, but it's very technique dependent, as every surface needs to be irradiated for it to work. Don't use ethanol though.
