In the studies I thought they were mainly quoting for that, I thought they usually showed there was similar reductions in both directions, but a greater reduction for source masking. That message somehow then got turned into there being no filtering for inhaling and that a masks only purpose is to protect others All that being strongly dependent on picking a mask that has decent filtration though, since many don’t and only some do. |

Like I said, masks rated for the job will do the job (of filtering the air you are breathing into your lungs).
