What is the comparative size of those bacteria and CV 19?

Did they test the total amount discharged around the leaks where the mask is not sealed or only that going directly forward?

E. Coli, the most commonly used bacteria in Micro classes is over 200x larger than Covid. It would therefore take a mask more than 200x more dense to stop an equal amount of virus particles from getting through and that doesn’t even consider all the leaks where the mask is not sealed around the edges.

Even aerosolized, very tiny droplets, can travel six feet and the larger droplets at least 21’.
