Don't use a mask, most are pretty pointless. Actually infection as such

The virus is heavier than air. With normal breathing it falls to the
ground within a few feet. If you cough or sneeze, it goes a lot further. A
mask by nature should help contain it.

I don't think you can really say that something a small as a virus is
"heavier than air". The droplets carrying it might be heavier than
air though.
