Surgical Masks
As its name recommend, surgical masks were initially meant for use during a surgery. The use was to ensure that the room might be saved sterile, and that germs from a health care provider or nurse’s mouth or nose wouldn’t contaminate the patient. Over the previous few years, it has seen commonplace use especially in places like China.

The ultimate layer focuses on filtration and in ensuring that the air stepping into from the setting is filtered. Some types of masks have an added special particulate air filters to help you breathe easier.
