The hoarded N 95 mask filters are useless against COVID-19
"Folks, let a surgeon of 30 years teach you about MASKS. COVID 19 virus particle size averages 125 nanometers (0.125microns); the range is 0.06 microns to .14 microns; one needs an electron microscope to see a COVID 19 virus particle. The hoarded N 95 mask filters down to 0.3 microns. So, N95 masks block few, if any, virions (virus particles).
This is a simple fact, so you just cannot argue against it. Other surgical masks, home-made masks and kerchiefs do the following:
They allow free passage both ways (in and out) of COVID 19 virions.
they become a warm, damp or moist reservoir of COVID 19 particles in asymptomatic "carriers" (estimated to be 85% of all people tested). For surgeons, years of training, intimidation, and humiliation teach us to touch NOTHING but our surgical field. Lay people constantly touch, re-arrange, and manipulate their "masks", wonderfully inoculating thousands of virus particles onto their bare or (even worse, gloved) hands.
So, these absurd masks ENCOURAGE the fomite transmission ("infected" articles-to-hand-to face transmission of the virus). So, go ahead and allow idiots to delude and mislead you to the false sense of security—and danger—of masks!"
—Doc Graham, MD
“The average healthy person does not need to have a mask, and they shouldn’t be wearing masks. There’s no evidence that wearing masks on healthy people will protect them. They wear them incorrectly, and they can increase the risk of infection because they’re touching their face more often.”
—Eli Perencevich, MD, professor of medicine and epidemiology at the University of Iowa’s College of Medicine
Here's why the vast majority of people should NOT be wearing face masks to combat COVID-19.
