Use of Masks ‘Looney Tunes’ says Dr. Scott Jensen
– When it comes to masks, this much is about a meter.
This much is about a millimeter.
When we talk about masks, we have to talk about microns.
And typically, if you look at an N95 mask,
what that does, is it filters out 95% of particulate matter
larger than .3 microns.
Well, the question then is how big is a COVID particle?
And a COVID particle is about .1 micron.
So we know that even an N95 mask
has tremendous limitations.
Yes, it does help some, because COVID particles will,
if you’ll will, coalesce and coagulate
almost as they come into the magnetized
or electrified field of the N95 mask.
But the bottom line is a surgical mask or a cloth mask
are really designed only for particulate matter
greater than five microns.
Typical bacteria are one to 20 microns.
So when we wear surgical masks in surgery,
we’re simply trying to make sure that if we sneeze,
cough, or something, we’re not spraying
a lot of bacteria into the place we’re doing surgery.
But this idea of people thinking
that they’re doing something particularly useful
with a cotton mask or a handkerchief
or a homemade mask or a surgical mask
is just looney tunes.
