Fun Fact: You can't see a virus with a normal optical microscope, no matter how powerful it is. You must use an electron scanning microscope to see a virus.
So if you can see the gaps between the threads of a mask with your naked eyes, how can you believe a mask can stop something that you need an electron microscope to see.
Isn't that like throwing sand at a cyclone fence and hoping the sand won't get through?
Thanks for showing me that I'm not alone. They taught this in 7th grade biology in the late 70's. We've known this since the 1940's.
