Basically yes, I’m making fun of the idiots who do not know what mask or how to wear one. I have been properly trained in the application and usage of various types of PPE for respiratory protection since the late 70’s/early 80’s. I wear respiratory protection nearly everyday at work also. I have worn full face
sealed respiratory protection (a SCBA unit) years back as a fireman. While no expert but I do know almost everyone I see is not wearing a mask that will do much and in fact there are people wearing masks that will send germs even farther ...

the N95 mask above actually has an
unfiltered exhalation valve which sends the wearers germs out tighter stream pattern and farther than the N95 below with out the e-valve like below ... both are N95 masks (but truthfully only the one below helps
prevent spread) ... E-valve type masks are designed to protect the wearer from particulates in the air when wearing and not to filter the wear’s breath.

As to surgical masks and such they they allow 60%
plus of particulates to escape out the sides over cheeks. Also half and full face canister respirators have a very similar e-valve type setup that spreads contaminates the same way. Homemade cloth masks actually catch germs and hold them for the wearer to breath them in at some point or even worse hold for a future wearing if the wear does not clean and disinfect the mask between wearing.
To put a twist on an old gun saying to apply to masks ...
just because you have a mask don’t mean you know how to use and wear it to protect yourself (
and others).
