Thank you for looking into this necessary subject. You don't mention any application to the domestic scene. I have a few N95 masks, left over from the last time the air quality here in BC necessitated wearing one. After use now for Covid -19 prevention, can I re-use these masks by putting them in the kitchen oven at 70 C degrees for an hour and at ambient humidity?
