Surgical Masks

As its name counsel, surgical masks have been initially meant for use throughout a surgery. The use was to make sure that the room could be kept sterile, and that germs from a doctor or nurse’s mouth or nose wouldn’t contaminate the patient. Over the previous few years, it has seen commonplace use particularly in places like China.

These masks are sometimes also called three-ply masks as a consequence of their characteristic of having 3 layers of protection within the masks itself. The layers are sometimes a consistent type of material relying on the manufacturer, although frequent ones embody wool felt, fiberglass paper, or polypropylene. The multi-layered construction of the mask acts to filter out particles more successfully, similar to how using multiple sieves in succession is more effective than just using one sieve.
