Exactly what I meant by "mask compliance". It's tough to measure and can only be done through self-reporting.

Respirator wearing is the only thing that works. Masks not at all for aerosol size particles.

Some percentage of particles are going get stuck in the mask fibers, thereby lowering the viral dose you get. There is no way it doesn’t help at least some, the question might just be how much.

Masks can't be sealed and all the studies that say they are somewhat effective use mannequins with perfect seals. Real world data from Florida shows schools with and without mandates had the same rates of infection which mirrored the general communities.

Stephen Petty, one of the top industrial hygienist in the world does an excellent job of covering all aspects of this: https://rumble.com/c/PettyPodcasts

That's not true. Here is a lit review that shows you multiple avenues of evidence that show masks are effective: http://files.fast.ai/papers/masks_lit_review.pdf

Again, mask wearing is effective. Mask mandates may not be. There is a difference, and the difference is compliance. If people don't actually wear masks, that's not evidence that masks don't work.
