SFPE-SEPS I have an old 3M FFP2 mask that I used at the time for work in my house. May I still use it (grocery shopping, for example)?  Could I leave it 3 days in a closed bag to kill the virus and then being able to re-use it?

No.

Mask efficiency against COVID-19 is not guaranteed with repeated use.[:]
