Medical Mask

Medical masks come in a few varieties and are less effective than N95s: Some filter as much as 60 to 80 percent of small particles under lab conditions. When worn properly, they can help prevent the spread of the coronavirus by catching droplets when you cough or sneeze.

Medical masks are often made out of layers of breathable, paperlike synthetic fabric that is cut into a rectangular shape and has pleats to help it expand and fit more snugly around your face. They are disposable and designed to be used just once.

While they can protect you from large droplets and splatter, their looser fit is partly what makes them less effective than N95s.
