While the graphic may be accurate with sizes, the issue is that the virus particles don’t float through the air, they are attached to larger water droplets but still capable of going through a mask.
If the water droplets are floating through the air, how large are they?
Unless a person is wearing an N-95 mask that has been fit tested, he will be breathing in particles that are 0.3 microns or smaller. Dust masks that most people were wearing, that do not provide an airtight seal, are not even very good at screening for dust.

Droplets don't matter when a virus is aerosolized-even if droplets are stopped, virus is still airborne and travels right on through
