Funny pics, coming out of Asia....of folks improvising.
I’ve wondered about using something like a dehydrator to ‘clean’ masks and other stuff. mine has temp settings every 5deg from 120F to 150F. This virus probably hates those temps.
I saw an informative post the other day. Take a Kleenex tissue, repeatedly fold it like an accordion, alternating the folds every half inch or so. Then wrap a rubber band on each end. Tie another pair of rubber bands to use as loops over your ears. Expand the accordion shape over your mouth and ears - instant face mask.
