Earlier in the pandemic there was a publication from India in which they examined the pore sizes of cloth masks. The pore size was typically around 500nm. The virus is 100nm in diameter. So obviously they do not work.

So, why can’t someone manufacture a face mask with a pore size much smaller than the coronavirus’ diameter?

Oh, they work.

But not as masks.

They’re muzzles.

That can’t he true. I always wear the facemask when walking between the front door and the bar and I have never got covid

Like having a screen door on a submarine.
