There's plenty of mask studies. The fact that you don't know about them, despite the 1.5 years of mask discussion, is because of your bubble. Not mine.
I've generally seen 60% efficacy from 2-ply cotton designs. The textile study from acs further broke that down into different cottons: tight 600 tpi cotton was more effective than 80tpi loose cotton.
> In comparison, the 100% cotton t-shirt had a 69% mean filtration efficiency for the 1 μm particles and 51% for the 23 nm particles.
And the big one is the NIH study, conducted relatively early when the mask debate was raging. By May 2020, they already finished their study.
T-Shirt cotton was over 60% effective.

Look, its very difficult for me to believe you're arguing in good faith. We're well over a year into this pandemic and you're bringing up talking points I haven't heard in over a year. Your talking points have been completely disproven a year ago.
