And discard them every few hours, if you don't want your "mask" being a dust collector with optional coronavirus inside. Reusable mask is more like element of style, a fashion item, not protection. I don't think that most people really clean it properly as required.

Anyway, it is pretty easy to make somewhat reliable single-use mask from any cloth. Take common nonwoven fabric that is sold for cleaning, take few layers, fold, cut - and mask is done.
