>Also N95s have to be fit tested to be effective. So randos buying N95s and wearing them will frequently not work. I don't think this is true. No box of 3M N95 masks I've ever bought has said anywhere "failure to fit test this mask renders it ineffective." 3M Aura masks have an instruction video on how to maximize the fit, but thats just a bit on how best to adjust the little metal bit that clamps around the nose. An ill-fit N95 that might not be perfectly adjusted to conform is still way better than a cloth mask which isn't intended to seal at all. |

Some masks are just incompatible with some faces, it’s greaT that Aura’s have an instruction video, that doesn’t mean it will work for all people.

I think you’re probably right. But I don’t know of a study that tests this because N95s are measured as conforming to spec, not when they are worn improperly without a seal at the nose and chin. I hope we get some info on this.
The Dirextors (and Fauci’s) comments weren’t about this though, they mentioned how N95s are uncomfortable and thus hard to wear consistently. Try wearing an N95 for 6 hours of school. Especially without training. I think the recommendation for cloth masks is because of the ability for people to wear them.
So the recommendation is not based around optimal standards of use, but around likely use.
This doesn’t mean that N95s don’t protect people. I wear them in public. I’m just trying to correct GP’s criticism that someone the CDC director’s comments are incorrect or illogical.
