Surgical Masks
As its name suggest, surgical masks have been initially meant to be used during a surgery. The use was to make sure that the room might be stored sterile, and that germs from a physician or nurse’s mouth or nose would not contaminate the patient. Over the previous few years, it has seen commonplace use especially in places like China.
These masks are often also called three-ply masks due to their attribute of getting 3 layers of protection within the mask itself. The layers are sometimes a constant type of fabric depending on the manufacturer, although common ones embrace wool felt, fiberglass paper, or polypropylene. The multi-layered structure of the mask acts to filter out particles more successfully, similar to how using multiple sieves in succession is more efficient than just using one sieve.

Some types of masks have an added special particulate air filters that can assist you breathe easier.
