Sorry, late to this party, but thank you for validating what I have been saying since all this idiocy started. As a multi-certified indoor environmental inspector, consultant and contractor, certified in selection, fitment testing and instructing others on respirators, the claim that a 95% efficiency down to 300 nm IF properly worn, fitted and frequently replaced mask can stop a 6-12 nm virus (even up to 100 nm as this article stretches to) is like saying you should replace all the screens in your house with chain-link fence to stop mosquitos. Then evil anthony tells people to wear 2 or even 3 "chain link fences" for more protection. The droplet argument is also flawed beyond measure and ACTUALLY describes the danger of detaining the virus until the vapor evaporates ushering a straight path to your lungs for the virus instead of leaving it in the air without the mask.
