That video you posted is a joke. Did you ask yourself why that guy didn’t put on an N95 mask?
N95 masks are not relevant in society because that's not what people wear. That's not what medical staff wear in medical facilities for day to day business. Lefties like to bring n95 masks up in mask discussions, since the actual filtration potential of them is remarkable, even though n95 masks don't stop covid either. As good as the filtration potential looks on paper though, contaminated air will still flow effortlessly around the mask upon exhalation. The extra filtration potential of n95 creates outward pressure upon exhalation, so the contaminated air pushes outward on the mask to create a path of least resistance. The contaminated air goes every which way until it fills a room, house, or building, just like cigarette smoke does. Just because a cigarette smoker exhales against a barrier to divert his smoke, doesn't mean that cigarette smoke won't fill an entire house within a minute or two.
Bringing up the n95 mask that we don't even see people wearing is grasping for straws. It is not required in any business that requires face coverings or masks, which is why we rarely see n95 in public. What it means when lefties bring up n95 masks, is that they already KNOW that all masks that are less than n95 don't work for covid. Lefties are relying on a mask that isn't being used in public or outside of environments where nosh approved n95 is required for specific hazmat. They are relying on the filtration potential of this to justify having society wear cheap cloth masks. What makes this even more pathetic is that the n95 STILL let's contaminated air, viruses, and droplets fill a room, airplane, car, or building.
