For decades, the boxes in which masks are distributed come with a disclaimer that
surgery grade masks are not apt for defense against biological agents and diseases.

A lot of items in the market have warnings that are to protect the
vendor from people that will not be careful and will treat their
product as though it can perform voodoo-magic. Masks help, but
they are not 100% - nothing is. Not even a vaccine, but it too helps
immensely.

Also, I'm really into home recording. Have you ever seen a pop filter? It's a (usually circular) screen that sits between a vocalist and a microphone. Its purpose is to disperse energy from plosives, vocal
sounds that involve projecting a puff of air (t, k, p, d, g, and b).

Does it protect against disease? No, but it's not intended to. What it does do is disrupt airflow to limit the range that a puff of air can travel, thereby preventing loud, distorted pops in the recorded
material. It also does a pretty fair job of keeping drops of spittle
out of the microphone.

If you need one but don't have one, you could make one out of a kitchen splatter screen and some pantyhose. There's nothing particularly
space-age about them.

And that's what masks do. Combined with social distancing, they can be pretty effective.

Jeff, Excellent real-world example of how masks help.
