I don't see an advantage in doing that if you have a few masks to rotate. Put each of then in a separate, labeled paper bag. If you have 5 masks, use one a day and repeat mask #1 in day 6, and no SARS-CoV-2 will be active and infectious on the surface of the mask 5 days later.

Please take COVID-19 seriously; don't panic but don't deny it; practice social distancing (stay 6ft from people); wash your hands a lot, don't touch your face, don't gather with too many people, so that you help us contain it.
