Viruses are 90 nanometers in diameter. This is very much smaller than the aperture of masks. Masks won’t stop the virus — but that’s not the correct measurement.

Because viruses pretty much never exist isolated in nature. They are always attached to some moisture molecule — and those are larger than the aperture. That’s why masks have value.

You just posted such stupidity, that you made my buddy Alberta doctor’s jaw drop.

I’d explain it to you, but I fear it would be a waste.

It says right on the box of masks they won’t work

Double masking stops aperture breaches.

They are always attached to some moisture molecule — and those are larger than the aperture.

A virus is huge compared to a molecule.

Really?

How long does the “moisture molecule” to which a virus is “always attached”, take to evaporate? A “moisture molecule” in the Texas summer? A “moisture molecule” in bone-dry winter air in Minnesota?

And they’re “larger than the aperture”, eh? Must be some hefty molecules.
