I am not a great fan or booster of the masks, particularly the herd mentality that has sheeple wearing them at useless and meaningless times, just to satisfy rules that are unable to put anything into context.
However, as to:
“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 authors assumptions are wrong, because they focus on the wrong facts.
1. It is not the size of the virus that matters, because the virus does not exit the body, in a cough, sneeze or the breath in a form where it is all by itself, just floating in the air.
2. The virus when it is expelled by the respiratory system in any manner is one of a number of things that can be part of a “droplet”. Droplets from all respiratory sources by all means of being expelled can range from 0.01 and 1000 microns, but the median size is from .7 to 1 micron.
3. While a virus no bigger than between .06 microns and .14 microns may be contained with a droplet that is between .7 microns and 1 micron, it does not then fly out of the droplet on its own. If the mask stops the droplet, the mask blocks any virus in the droplet. N95 masks are efficient against 95% of droplets between .3 microns and larger. Surgical masks are not terribly less efficient but do permit more incoming airflow around the boundaries of the mask, compared to the more closely fitting N95 type. While nothing is perfect, and some small portion of droplets may be larger than .3 microns, masks also have to allow for sufficient air to breath.
4. As to home made fabric masks, their makeup is so diverse in composition there is no telling how efficient they are.
