It says single layer cloth there, not double :)

What I did strange is that the cloth masks are mostly stuffier and harder to breathe than the surgical ones, which filter much better.

The FFP ones are of course the worst to use but also the best at filtering.

Either way I can't wait till we can safely get rid of all of them though... I wish there were powered ones with fans to pull in filtered but fresh air. But the only one I've seen is the Razer Hydra and it's always out of stock. It's also huge and looks like a WW2 gas mask so it's not really street smart.

The study included single and double layer; both were an increase vs no mask, but only single was statistically significant.
