As the coronavirus pandemic spreads, N95 filtration masks are in short supply worldwide. It remains unclear whether wearing a mask as a prophylactic is necessary, but that isn’t stopping people from strapping them on when they venture outside their homes. And if you are infected with the COVID-19 virus, or you are working closely with infected people, then you probably do want a mask.
Can these masks be reused? New guidance from Stanford Medicine says yes, you can sterilize N95 masks — by “baking” them in a low-temperature oven. However, you should definitely not do this at home.
