MYTH: MASKS ARE INNEFECTIVE
An N95 mask is effective for a virus the size of the CoronaVirus even if airborne and not in droplets.

MYTH: MASKS CANNOT BE REUSED
You can probably sterilise a used face mask ub an oven for an hour at 60ºC. Compare it with 67ºC for SARS-CoV-1 which also is inactivated at 75ºC for half an hour, so my guess is that should be plenty for SARS-CoV-2. There is also a similar method for E.Coli.
