If you want a 'mask' to work, you need a respirator, the type you see body shop painters using. There is a definite seal around the mouth and nose. Air passes through a filter that captures any virus.

This. Paper masks, cloth masks and similar can block droplets. They are essentially invisible to aerosols. The predominant mode of transmission of Sars-cov2 is aerosols. There is some droplet transmission, but if you aren't around people sneezing in your mouth, that one is easily avoidable.
Back in 2009, I was painting our house in NJ with an airless sprayer. I bought some of those blue masks, figuring it'd do something. It didn't do anything. My beard under the mask was just as covered as what was outside of the mask.
I used to infrequently paint cars in the late 80s, so I grabbed one of those old smelly full faced ones, put a new filter in it and finished the job.
