I was hoping this covered how to sanitize them (I had a couple N95s in storage that I've been reusing when out shopping. I live in Redmond/Kirkland, the initial epicenter). I've heard some hospitals are lightly bleaching, and I'm curious if my Everclear sprays would degrade the barriers.
What a crazy time to be living.
- malandrew 7y agoSince alcohol helps, I suspect soaking them in 70% ethyl or isopropyl alcohol and letting them dry should work for coronavirus at least. I reckon alcohol will also do less damage to the mask than bleach. If you want to try both alcohol and bleach just don't mix alcohol and bleach at the same time as that will create chloroform. https://www.ncbi.nlm.nih.gov/books/NBK214356/ https://www.ncbi.nlm.nih.gov/books/NBK214356/ edit: ignore the idea of using alcohol as it will destroy the electrostatic absorption of an N95 mask.
- malandrew 7y agoHere's a better resource: http://www.imcclinics.com/english/index.php/news/view?id=83 http://www.imcclinics.com/english/index.php/news/view?id=83 Key excerpt: "The new coronavirus is sensitive to heat. It can effectively inactivate the new coronavirus by heating for 30 minutes at 56 degrees Celsius. Therefore, the single dry heat sterilization (70 degrees Celsius heating for 30 minutes) can effectively inactivate the virus without affecting the protective function of the mask."
- Darkphibre 7y agoThank you so much!! Alcohol can cause crazing or stiffening in some plastics, so I worried about potential foams in the filters. In fact, that was covered by your article: 2. The disinfection method of spraying alcohol on the mask will destroy the electrostatic absorption of the mask, causing filtering efficiency of the mask lowering below 95%.
