Masks do protect the wearer! And you do not need an N95 mask to do this. Even a simple homemade mask offers some degree of protection. This[0] was a good explanation of both of these ideas.
tldr: There is reason to believe that large droplets, not the tiny droplets that N95s are designed to filter, are the primary threat, and any sort of physical barrier between those and your mouth/nose will help.

- ejolto 7y agoThanks, figure 5 is especially interesting since it implies it gives the wearer of surgical masks some protection.

- rv-de 7y agoI think the idea that larger droplets are required for an infection is congruent with an R0 of about 3. If super small droplets would be sufficient then a single person would easily infect pretty much everybody taking a bus with her/him together. R0 would be much larger.
