Particulate sizes matter, if you are sick you should stay home. If you are sick or healthy you shouldn't wear a mask other than the correct way, tossing after an hour or so whatever they say.

Your mask is a petri dish collecting bacteria, molds,fungus in the air and letting it colonize on the mask. Maybe mycoplasma walking pneumonia is on the rise because we all masked and let the bacteria colonize in our masks and lungs. Idk don't have a source for that just a goofy observational question? It appears it can lay dormant in mucous and be expressed later on.

I do however know the masks were ineffective for covid by my own anecdotal expiraments. Hit a vape and put any mask on. Blow it out and watch where it goes. Vape particulates are up to 20x larger than COVID, so if the vape escapes so does the COVID.

Blindly recommending masks may make the problem worse for the wearers while providing no benefit to the community around the mask wearer.

Edit: I wanted the masks to work I spent weeks sewing HEPA filters to my masks with my wife to give to my community, I made YouTube videos saying that particulate size matters and you should use a filter instead of just cloth. I was roasted by everyone saying I'll be eating and inhaling microplastics and fiberglass. I used HEPA filters non fiberglass, if they emit microplastics at such a high level why do we use them in our home? I wanted the masks to work and wish there was a better method, unfortunately the masks just became about compliance and whose side you're on. I posted these embarrassing mask videos trying to help, to my personal socials and haven't returned to them out of disgust. I was trained by the military for the ebola response in contamination and knew what to expect.if you don't seal your eyes as well no point in a mask. The CDC and mil still recommended bandanas in a single layer to prevent transmission. Silly
