Surgical Masks
As its name recommend, surgical masks were originally 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 health care provider or nurse’s mouth or nose would not contaminate the patient. Over the previous few years, it has seen commonplace use particularly in places like China.
These masks are often additionally called 3-ply masks due to their attribute of having 3 layers of protection within the masks itself. The layers are often a consistent type of material depending on the manufacturer, though widespread ones include 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.
By a one-time use, the layers will start changing into soiled or clogged as they block out particles from each outside in and inside out. As there are no solution to safely clean out these layers at home, it is highly recommended that these masks be disposed on the end of its use.

These respirators have key parts that makes it completely different from a surgical masks:
The primary is the shell, which has three key layers, typically more. The outer layer is a protective cloth which acts as a barrier between you and the environment.

The final layer focuses on filtration and in guaranteeing that the air moving into from the atmosphere is filtered. Some types of masks have an added special particulate air filters that will help you breathe easier.
