I've noticed that in all threads about masks where mask function is function is discussed, lefties use the n95 as the benchmark when they want to show benefits of wearing masks. The problem though, is that the n95 is not what people are wearing. Forget for a moment that the exhalation valve let's 100% of droplets out unfiltered, just look at the availability of the n95. Why would lefties use the n95 as a reference if it is not being used? Why not look at the simple surgeon masks or cloth masks that people are actually using? Using n95 specs to justify wearing simple cloth masks or surgical masks is a scam. Using n95 filtration specs to do this while also claiming that masks protect others is a scam as well, since the exhalation valve allows unfiltered exhaust. Lefties can't help scamming.
