  That's not surprising considering the link I posted. My question is whether the mask protects the wearer, and if not, why would the filtration only work in one direction?

    Are you really wearing a mask which is tight enough that _all_ of your respiration is going in and out through the material? If not, your argument/question about filtration isn't very relevant.

    Thinking about it some more, I suspect the disconnect between us is that you think the primary way of getting sick is breathing the airborne virus. Whereas I think the primary way of getting sick is touching your eyes (or picking your nose). So you want the filtering to be good, but I just don't want infected snot droplets to be blown everywhere. Now, I'm sure someone will throw an obnoxious "citation needed" reply...
