He then argues that masks don’t work because viruses are small enough to pass through them. The problem with this reasoning is viruses do not travel as individual viral particles- they are inside the aerosols and droplets. That’s what the masks block.
"Aerosol droplet lands on mask, dries, virus gets inhaled"
sounds plausible to me
His source for mask efficacy has multiple sources which conclude single digit % reductions. And the only one with a blind test concluded "no effect".
If we take the vx vs palcebo study I linked then maximally reduces the transmission chance from 4% to 3.6%.

It's all so tiresome
The effectiveness of masks is vastly overstated in the mass media in order to get people to wear them. I'll take a couple of percentage points.
Also, I think the idea is reduce the spread from the wearer.
