You do realize the mask has zero protection from viruses.
Still better than any other mask, especially when people are flinging spit when they talk. Other people have flimsy cloth masks, or improper fits with their nose exposed. We bought expensive N95 double-insulated with tight fits that pretty much stop air from moving around the edges. Got a large box of them, and discard the masks regularly. Of course, I'm aware of the tiny size of viruses, but I want to limit the spit flingers easy access to my nose. BTW, a grandchild wears a cloth mask which is pretty much useless against any incoming disease - but that's the case with most people who are mandated to wear masks (still a requirement here for entering businesses).
