Since the CoronaVirus has a limited lifecycle outside of human body (up to 3 days on different surfaces) can the masks left unattended be reused?

If not, why? What are safe ways to disinfect face masks in household conditions?

Edit: Some have claimed that virus on the surfaces can stay infectious for longer than 3 days. I was unable to verify this claim, however. Please do your own research and don't believe what some guy on reddit said.

The newest CDC guidelines contain several reuse strategies, the easiest - if you still have supplies, that is - is to dispense 5 masks/respirators to staff. Have them number them and or the bags they go into, using one mask per day and then placing it into the paper bag (please be careful not to contaminate the inside of the mask). After the fifth day, you start over at mask #1. The research from UNMC suggests that after about 3 days they don't seal well and need to be tossed, but with the rotation that could get you several weeks of use.
