The logic of wearing a facemask is very simple. When you sneeze the mask then prevents the sneeze particles from hitting other people. That's important because if you have COVID-19, then those sneeze particles could easily get someone else sick. It's a concept so basic that it falls in-line with principles you could teach a preschooler like why poop goes in the toilet and not all over the nap corner. So why is it that actual adults are purchasing these:
Those are mesh facemasks, and they're about as effective at stopping a sneeze as a mesh diaper is at stopping runny diarrhea from splattering against the floor and getting all over your classmates. It seems the people purchasing these masks realize this fact because when you look at the comments section, you'll see someone mentions donning them for "compliance." They know the masks are ineffective, but they're wearing them, so they don't get turned away from Trader Joes.
Why, if they're going to go through the trouble of putting on a mesh mask, can't they just put on a regular mask? Maybe it's because they feel that inconvenienced from breathing in their own breathe. Maybe it's because they want to be able to smell the Trader Joes Cookie Butter in its entirety. I'd be fine with whatever reason, presuming the risk they took on by wearing a fishing net strapped to their face was to themselves. The problem is the risk is to us.
As you can see from this chart from the CDC, surgical masks (and most masks worn by everyday people) aren't designed to protect the wearer from airborne particles. It says, "Does NOT provide the wearer with a reliable level of protection from inhaling smaller airborne particles and is not considered respiratory protection." Our respiratory protection only happens when the people around us wear a mask. You could call this using proper hygiene. Some of you might say to this, "well, you can't control the people around you; you can only control yourself." That is true. But I'd also argue that if we're able to convince a majority of the population not to shit where they stand for the betterment of society, then this is something that we should start teaching as well.
