Well you didn't pop mine, but I will give you a failing grade for not posting up a . Pre number or the correct numbers.

The COVID-19 virus is 0.125 microns and N95 masks only filter down to 0.3 microns so how can N95, surgical or cloth masks be effective?
A: While the size of the virus itself is very small, the virus particles do not travel through the air alone. The virus needs to hitch a ride on the tiny droplets of saliva and water that are exhaled when someone coughs or sneezes, or even on dust particles. Shouting or singing can also disperse these droplets widely. If you are infected with COVID-19, you likely contracted the virus from inhaling viral-infected particles. It is also not true that N95 masks do not filter particles smaller than 0.3 microns, they can and do. There are multiple layers of fibers that carry an electrostatic charge that helps entrap these smaller particles.
While there have not been large-scale controlled trials,
recent research shared in the Journal of Aerosol Science shows that masks protect people surrounding the mask-wearer. This research indicates that masks are effective at trapping exhaled air and respiratory droplets in the mask and successfully limit the number and movement of viral particles on droplets in the air. We can also draw some
So important to not throw things at walls to see if it sticks.
