Viruses are 1/8 micron, but the masks are for droplets, 1 micron and larger. At scale the mask fibers are electrostatic and very roughly about 75% of droplets stick to the fibers. The mosquitoes would similarly stick to the fence if you scaled the electrostatic fields to those larger sizes. But you are correct that mosquitoes would fly around the fence. That's a correct analogy.
MAybe next time you can talk about the vaccine. I'm not against vaccines and will get J&J at some point in the future. But the vaccine passport or anything like it is an abomination As the leftist Naomi Wolf pointed out on Bannon's show, it is the Chinese communist social credit system imported to America in the blink of an eye.
I have studied the masks and stand by what I say.
