Masks always provided some benefit both ways, but the benefit is maximized if everyone is wearing them. N95s and similar have started to become more common, and those have substantial benefit to the wearer, even in a crowded room of unmasked people. If I am wearing an N95 and you are not wearing a mask, I am more protected than if both you and I are wearing surgical masks. |
