dude ... 30 years in the medical field. M-95
Post# of 123686
30 years in the medical field. M-95 filter to .3 microns. C-19 is .125 microns. Simple math. Spray from breathing cough or sneeze with mask travel about 1-2 feet and hangs in the air up to 8 minutes. Then you have cross contamination.
I follow state guidelines. Most don't wear M-95 masks and most don't cover their nose either. Fedex mask was a absolute joke...just to adhere to the state mandate.
However...I will say you mask idiots are really nuts.
Yes I know you will follow well nurses and surgeon wear them. Well sweetheart Gems are .500 microns... so masks work....just not for viruses
