Medical masks

Medical masks are loose-fitting and disposable. They're meant to protect you from droplets and sprays, such as mucus from a sneeze. Also called surgical masks, they filter out large particles in the air when you breathe in. Medical masks come in a larger size typically used for adults and a smaller size that may be used for children.

To make medical masks more form-fitting, knot the ear loops where they attach to the mask. Then fold and tuck the loose material under the edges. Also, make sure to pinch the flexible nosepiece if the mask has one. This creates a snug fit over the bridge of your nose.
