That's what is posted in our local media. I'm not sure if it comes from local gov agencies or WHO or something else.

FFP2 / N95 respirators - 90-something percent, medical "blue" masks - 80 percent, home-made piece-of-cloth style ~ 50%.

Wearing sunglasses is encouraged too. Both to stop the load if someone sneezes at you and discourage from touching your eyes.

N95 - 95% at least.

Medical mask - 96,4%.

Home made mask - 60-96% (depends on cloth and sewing).

Maybe you and I have different medical masks in mind? I was talking about masks like this:

The main problem with blue masks and home made is that they tend to get wet from breath and their effectiveness go down the drain.
