Do N95 respirators provide 95% protection level against airborne viruses

Background: Respiratory protection devices are used to protect the wearers from inhaling particles suspended in the air. Filtering face piece respirators are usually tested utilizing nonbiologic particles, whereas their use often aims at reducing exposure to biologic aerosols, including infectious agents such as viruses and bacteria.

Methods: The performance of 2 types of N95 half-mask, filtering face piece respirators and 2 types of surgical masks were determined. The collection efficiency of these respiratory protection devices was investigated using MS2 virus (a nonharmful simulant of several pathogens). The virions were detected in the particle size range of 10 to 80 nm.

Results: The results indicate that the penetration of virions through the National Institute for Occupational Safety and Health (NIOSH)-certified N95 respirators can exceed an expected level of 5%. As anticipated, the tested surgical masks showed a much higher particle penetration because they are known to be less efficient than the N95 respirators. The 2 surgical masks, which originated from the same manufacturer, showed tremendously different penetration levels of the MS2 virions: 20.5% and 84.5%, respectively, at an inhalation flow rate of 85 L/min.

Conclusion: The N95 filtering face piece respirators may not provide the expected protection level against small virions. Some surgical masks may let a significant fraction of airborne viruses penetrate through their filters, providing very low protection against aerosolized infectious agents in the size range of 10 to 80 nm. It should be noted that the surgical masks are primarily designed to protect the environment from the wearer, whereas the respirators are supposed to protect the wearer from the environment.

Nick Note: I really really really do not want to be in this fight……. really Really REALLY! But i am trapped. Its called the fucking N95 respirator because AT BEST it filters out 95% of water droplets. I did not make the SHIT, i did not name the shit and i sure as hell did not sell it. I did give a fortune of them away. And as our knowledge base expanded and the virus mutated to my horror i realized the shit does not work. So i researched a solution… based on science, reports in credible scientific journals, industry standards, lab testing mine and supplier and the conclusion i came to is a 95% effective coffee paper filter material mask that lets 5% AT LEAST of water droplets through and a hell of a lot more vapor and nanoparticles is not acceptable. So i put together a solution looked for suppliers and out of desperation i have spent another fortune sourcing and inventorying and testing and supplying what i regard is a potential life saving solution. ANd that means that our trades will do great because the Plague is out of control, government is lying to you and the solutions they offer are a sick joke. I REALLY REALLY REALLY DO NOT WANT TO FIGHT WITH THE POWERS THAT BE… BUT I HAVE NO CHOICE………… SO HERE WE GO AGAIN..

By the way what researcher is going to come out and publicly and say the N95 masks are a joke. They are and will as you are seeing sighting the research. Just like the bullshit vaccine that will never come in time, And the toilet paper N95 that you can wipe your ass with (it is a outrage that they are telling people they are reusable) Soaking the toilet paper N95 in alcohol  reduces the electrostatic filtering properties letting even more bacteria through…… the N95 does no work adequately to protect you in the best conditions and their is a lot of science, dead and sick health care professionals and a second wave of the virus that is out of control to prove it.
