The virus is something like .01 microns in size. N95 only filters down to .03 microns. How can a mask block something smaller than it's rated to block?

those little microns sit in water

The virus does not travel alone. It is carried by water droplets, who are much bigger and easily stopped by the mask.

I'm still waiting for a source on the air transfer part.

You just reddit 😂https://wwwnc.cdc.gov/eid/article/26/5/19-0994_article In case you need another source: this is the CDC - click on the link that leads to methods and results

Forgive the pun. The redditor in me still shines through every now and then

N95 masks are very effective for the smaller particles; 'attractive' properties of molecules result in their getting captured by the fibers. This is why you can't wash and re-use them, as it ruins these properties. The mask are also effective for larger molecules. It's the mid-sized molecules that are harder to effectively block and in fact the N95 moniker means that the mask blocks 95% of mid-sized molecules.

There are numerous vids on YT that explain it fully, if you're interested.
