"I wonder how long the virus persists on a mask. If they could be left unused for a period of time then reused, that could help, especially for the layman."

For days.

For homemade masks only:

After replacing each mask on the face, touch only the strings or bands to take the old mask off, and put it in a bag. Seal the bag as well as possible.

When home, drop the masks (and your clothing) directly from the bag into a tub of hot water and plenty of laundry detergent outside. Put a lid on the tub. Leave the shoes outside if possible, or someplace outside of your indoor living spaces. Go directly to the shower.

Make sure that the masks are very thoroughly, repeatedly rinsed with warm water after washing in order to avoid allergic reactions to the laundry detergent. Dry the masks thoroughly (preferably in a dryer or by hanging in the sun).

The material for the homemade masks should be boiled before sewing the masks, by the way, to make sure that the completed masks will fit snugly to the face all around after washing later on.
