“The mask is not an adequate defense against the COVID-19 virus, gang. The virus checks in at somewhere between 0.06 and 0.14 microns, meaning it’s too small for any commercially available mask to effectively filter it out. The pores on an N95 mask, which are the best masks you’re reasonably going to find, and the vast, vast majority of you are not going to have N95 masks but rather cloth masks which perform far less well, are 0.3 microns.”
Wrong. Why?? Because we are not talking about the need to filter “virus particles”. Bare virus particles simply don’t exist in the particulate emissions from sneezes, coughts, speech, or breathing. Those emissions are basically water drops with various concentrations of salt and other chemicals from the human system, and far larger than the quoted 0.14 micron size quoted.

The author is also wrong because he fails to account for "Brownian motion." In short, Brownian motion is the erratic, random motion of particles smaller than .3 microns that occurs when they collide with molecules while suspended in a fluid or gas. In other words, while the Wuhan flu virus would pass through an N95 mask if the virus were to travel in a straight line, because of Brownian motion, the virus snags itself in the mesh rather than passing through.
