Do not wear your face mask like the gentleman front and center in the photo! Not covering your nose has become the source of many memes but it still widespread. Simply having the fabric on your face does not grant you a protective aura.

The primary purpose of everyone wearing masks is so that people who are asymptomatic or pre-symptomatic minimize the spread of their droplets to everyone else. If the mask also protects you from sick people, that is an added benefit but secondary. Only N95 masks worn properly can guarantee protection for the wearer.

That means covering the mouth is most important because even breathing releases droplets. And the nose should be covered too, but only covering the mouth does help.

"Guaranteed protection" does not matter at all.

Masks that only offer 99% protection are well worth wearing. As are 40% masks.

Only when worn properly, a 20% mask that you take off with your hands from the front and then don't watch your hands or any other uncareful behavior when using it is going to make more harm than good and for those it would have been better to not wear anything at all.

I can see how touching the mask can lower the protection.

To categorically say it always makes more harm that good seems entirely wrong!
