I RO at a training range that has shoot houses and a CS chamber that local law enforcement use for qualification to use tear gas. I offered anyone who said their non medical cloth masks do something to come and try it out in the CS chamber and the CS gas molecules are much larger than viruses.

Nobody would take me up on the offer.
