Example of how the purpose of masks for ordinary people is still not understood. The ones with exhalation valves, including N95s, should not be worn around people, period.

There are two purposes of masks: protect the wearer from infection AND/OR protect others from wearer's potential transmission. For medical workers, both are important. For regular people in most settings, it's about the latter. Cotton mask will do that; an N95 with valve WON'T.

There is a weighting, for input versus output for normal folks, but I'd still argue that it's both. "You can wash your hands, but you can't wash your lungs"
