There is a crucial rule when putting on a fabric mask or a face mask with wrinkles.
Are you wearing your mask the right way around?
Have you gotten a fabric mask or a face mask that has the typical folds for fanning out over the mouth and nose? When putting it on, for optimal protection it now depends on how you put the mask on.
Masks with wrinkles are worn so that the back of the folds face down. The WHO shows this in its graphic using a wire mask. It should always be over your nose. The folds then automatically point downwards. And also explains that, when the folds point downwards, “fewer dust particles, pollen, etc. accumulate in the” pleated valleys “.
