I don’t know which mask he’s wearing, but if it is an N95 or a N100 mask either of them aren’t going to help much.
Why?
The Ebola virus is 0.08 microns in diameter.
The N95 mask filters down to 0.3 microns and the N100 mask, 0.1 microns.
Where’s Ron Klain when Presidente 0bola really needs him? And his media suppression skills.
The N 95 should be more than adequate. It is not the individual virus that is airborne, but rather virii in a droplet of secretions. All droplets of secretions should be a good deal larger than 0.3 microns.
