Not much use at all as a preventative measure as once they are damp, they don’t work and because of respiration they become damp fairly quickly and any virus would just seep in or out.
Even if you only wear them for a short while, if it has been contaminated, you could still infect yourself by handling the mask as you take it off and dispose of it.
