didn't I tell someone to put N95 masks out in the sun to kill the virus between uses? Yes you did. I also found more detailed info on page 21 of this lengthy article (pdf): Alternate use among several masks. After using one, put it in its own bag to let virus decay for several days. This is best if you aren’t sharing your mask with anybody else to avoid unsavory bacteria. • For rapid decontamination: place in oven at 70oC = 160oF for 30-60min, or put in a steamer (not in boiling water, but the steam above it) for 10min, or expose both sides in a UV sterilizer (40W 2ft away). Mask efficacy is unaffected by these treatments (right). Alcohol and bleach are not recommended as they affect the electrostatic membrane that assists with virus filtration (right). 3/20 update: To protect against objections of rule-lovers, I’ll point out that UV sterilization and reuse of masks is now being done by hospitals (nyti.ms/3b8C1HQ). More recently I saw somewhere that covid requires much higher temperatures (90C) than recommended above. I've been leaving my mask in direct sunlight for about 1 hour, both outside and inside surfaces.
