As its name recommend, surgical masks had been initially meant for use during a surgery. The use was to ensure that the room could be saved sterile, and that germs from a health care provider or nurse’s mouth or nostril wouldn’t contaminate the patient. Over the previous few years, it has seen commonplace use particularly in places like China.
These masks are often also called three-ply masks due to their attribute of having three layers of protection within the mask itself. The layers are sometimes a consistent type of fabric relying on the producer, although widespread ones include wool felt, fiberglass paper, or polypropylene. The multi-layered structure of the masks acts to filter out particles more effectively, just like how utilizing multiple sieves in succession is more efficient than just utilizing one sieve.
