This type of mask is perhaps one of the more common masks worn by the public. It serves as a disposable barrier between the nose and mouth of the wearer and the contaminants surrounding them.
This type of mask is usually saved for and worn by medical personnel because it fits tightly around the nose and mouth, being even more secure in the spread of disease/sickness.
Cloth masks are the other more commonly worn face masks, as they provide around the same amount of protection as the surgical ones. However, unlike the surgical masks, these are washable and can be worn many times.
