So many people in both national media and social media parroting the info that masks which are not perfect or not perfectly fitted are worthless, when in reality a smaller viral load (such as a partially blocked cough or a percentage of droplets being blocked) can actually lead to lower mortality.
I've been wearing a homemade mask when I go out to the grocery store. I think of it as a last line of defense if someone should cough in my direction. I know the virus is .02 microns but it's being carried in a droplet of liquid that's considerable larger and may get caught by the two layers of dish cloth with a sheet from an air filter between them. I sewed it to fit securely around my nose and mouth and it extends all the way around the sides of my face.
Actual paper comparing homemade masks said they were about 70-80% as effective as a commercial N95 mask. Both are equally effective at preventing you from touching your mouth and nose.
