Update:
I just did some online reading of a recent journal article that has measured the SARS-CoV-2 virus. They reported a diameter of ~ 60 - 140 nm, or 0.06 - 0.14 microns. So again, this is significantly smaller than what an N95 mask is going to filter out (0.3 microns). However, assuming it is suspended in a droplet of secretions (mucus, saliva, etc.) it may be slightly larger. It seems reasonable, therefore, that an N95 MAY filter SOME of the infected droplets, but the personal protection still seems minimal to me. A better approach is simply maintain a 6 feet separation distance, and don't let someone cough or sneeze directly on you. But, if you think you may be sick and absolutely HAVE to go out, then wearing one will protect others.
