I believe you are completely misinformed on the mask. There are very few masks out there that can protect anybody from an airborne virus, and the few that are have been sent to only health professionals.
These surgical masks and homemade masks are not effective against the teeny tiny little virus like CoVid 19 or any other Coronavirus or rhinovirus.
Someone posted a picture recently of a chan link fence, and explained that wearing these masks is like trying to keep mosquitoes getting through chain link fence. It’s impossible.
The “experts” tell us that wearing masks is to protect others from getting our germs, not the other way around. So if you feel a need to wear a mask, then it’s an indication that you think you might be sick, or a silent carrier.
You are misinformed. Virus is not shed as individual free-floating fomites. Viruses are expelled from the body attached to droplets of spittle and mucous. The droplets of spittle are large and are trapped by the mask. So in your analogy, the mosquitoes are trapped inside balloons, and the balloons are stopped by the chain link fence.
