> Almost nobody doing industrial work with comparable PPE doesn't spend at least 1-2 hours of a typical workday out of the PPE.
Which leaves many thousands of hours in PPE, for many thousands of people. If the N95 masks caused health issues, we'd know. If someone can demonstrate a) a mechanism and b) any evidence for such an effect, I'm all ears.
It does, and I think that's a reasonable argument & comparison, but it isn't the same as the one you were making initially, which is all I'm pointing out.
