“RCTs did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks.
There were no clear differences between the use of medical/surgical masks compared with N95/P2 respirators in healthcare workers, when used in routine care to reduce respiratory viral infection.
It takes a special kind of stupid to believe you are protected by an N95 mask against COVID-19 when you consider the smallest particle an N95 mask can filter measures 3 microns when the smallest COVID-19 particle measures .003 microns, which is over 300 times smaller than the smallest particle an N95 mask can filter.”
