The only thing the mask helps with is being sneezed on, coughed on or otherwise spit on. Then you have to remove the mask and replace it immediately.
Far more important is what you touch.
Saw a funny one last night, a drive-through graduation ceremony. The principal, wearing a mask and surgical gloves, was handing diplomas to the kids as they drove by. And he shook hands with each one of them, never once changing gloves!

Placed under the microscope, even the dullest grain of sand develops a personality. So it goes with farts. (Or “flatulence,” as they say in the scientific literature.) Farts may seem largely interchangeable, but each one is special. Even just your own farts are a circus sideshow of intestinal gas: big ones, little ones, stinky ones, oddly fresh ones. There is not enough scientific evidence to say that no two farts are alike — but you can rest assured that they are a riot of diversity.
As a result, it’s impossible to say exactly how much space a generic fart takes up in the body. I can, however, tell you about the range of specific farts, as captured in scientific experiments. For instance, a 1997 study of 16 Americans found a volume-per-fart range of 17 milliliters to 375 milliliters.1 Imagine a bottle of nail polish — that’s a rough analogy for the volume of the daintiest of poots. Now imagine a can of soda. That’s the volume of a really big stinker. Your body is a wonderland.
But there are another couple of questions floating around this data. First, obviously, “How does one collect a fart?” And I’ll get to that in a bit. But second, and perhaps more important, is this: “Why study the gas volume of farts?” That’s a really interesting question if for no other reason than the fact that Dr. Michael Levitt, a researcher at Minneapolis Veterans Affairs and the grande sieur of fart research, doesn’t think there’s much value to the data. “It’s just physiological fact,” he told me. It’s interesting to know the volume of a fart, but it doesn’t have a lot of deeper meaning.
If masks alone worked well against viruses, then why are all the CDC and researchers wearing full HAZMAT suits? I'm pretty sure that my homemade bandana mask is fine.
I was waiting in line at the post office in my town the other day. In my county, you are required to wear a mask in public indoor spaces. The woman in front of me was wearing hers, but periodically would pull it down to wipe her nose, then pull it back up again. This after using her hand to open to door to enter the post office, and then again to open the inner door to the counter area. She had no concern about what her hands were contacting, and no concern about contacting her nose with those hands. I bet she catches every cold and flu that's going around.
Hard to say. They go through underwear and bluejeans quite well, but coveralls seem to funnel them up to your nose.
Chest waders are the absolute worst.
The disposable paper coveralls I used to keep the grease and crap of my clothes while cleaning equipment did a fairly good job of funneling too.
