urge the people that think it’s too risky to attend to wear a respirator, instead of requiring everyone to wear one.
Yes, that is the policy I recommend at the end of the post.
doesn’t take into account the current covid variants that are far more contagious than the early-to-mid 2020 strains
I don’t think that affects the argument in the post, which is about relative risk? Unless you’re saying that the new variance are better at getting past cloth/surgical masks but not at getting past P100s?
No one should buy that thing. It’s a (not NIOSH-approved) knockoff of the 3M 6000 series.
The filters claim to be NIOSH approved; are you claiming they’re counterfeit, or that the solid portion is uncertified?
You’re right; I missed your end-of-post recommendation.
Yes, I’m saying that the newer variants can easily get past cloth and surgical masks but are highly unlikely (but not impossible due to faceseal leaks) to defeat elastomeric respirators equipped with P100 filters. This is due to the fact that P100 filters filter out nearly all particles, so the contagiousness of a virus doesn’t matter that much. Here’s another way to think about it: during a poison gas attack, what would you choose, a water-soaked handkerchief or a gas mask?
The whole thing (facepiece and filters) is a knockoff, and as far as I can tell, it’s not NIOSH-approved. Again, you can check for yourself.
