I have one major critique of this video. He did not test an actual NIOSH certified N95 mask. I would have liked to see that. It is a fact that N95 masks, when properly fitted (we all have to have fit testing done) and worn by medical personnel, and properly removed and disposed of when no longer needed, work to prevent viral transmission via respiratory droplets. The first mask is not an N95 mask, although it resembles one from the outside. It is also a fact that moisture will degrade the mask significantly over time. This is precisely why mass masking the population does not work, and studies show this. This is also why it was always recommended against in previous pandemics. There is a possibility that the masks become vectors of disease transmission as well. Surgical masks, cloth masks, bandanas, etc, don't do jack. The masks are just a part of the whole fear campaign to weaponize the virus.
It is my understanding that the particle size is the Covid virus is so small it passed through even N95 masks. They do very little to prevent the spread of this virus.
