@Awakened Masks were invented to keep dust out of the lungs of construction workers. Dr.'s and nurses only wear them to prevent them from contaminating the patient being operated on. No one has any proof that they block viruses, but we do have solid proof on the threads distance on the N95 masks is 80 microns, and a virus is only one micron. Wearing a mask does not block any viruses at all. It is like using a chain link fence to block mosquitoes.
