As it is elastic, I'm not sure it is a good COVID-19 face mask, right?
It has ups and downs. Single layer elastic scarf will have lowest filtration, but still better than
nothing and better than an ill fitting stiff mask. Elasticity improves fit and wide coverage down
to the neck makes that side fit perfectly. FIltration can be improved by having the scarf have
two separate layers, it also makes it better as an actual scarf for autumn/winter use. Need to
make sure that the material can be ironed as that is the easiest way to keep it disinfected
In the end it may not be as effective as a properly worn surgical or N95 mask, but it can be
on a similar efficiency level as a cotton mask (especially for source control of droplets) and
is easier to wear and easier to carry around while not actively wearing it.
It is also quite on-brand for Debian, I seem to remember quite a few people wearing such
scarfs in past Debconfs for various uses.
