Usually, the nasal area and mouth is covered with the medical face masks. There are many types of stylish face masks available in the market. The cloth mouth mask and the disposable ones deserve special mention because these are mostly used by common people all over the world. • If you are using a protective cloth mouth mask, it is important to wash it and sterilize it properly after every use. In that way, the germs residing on the external portion will be eliminated. • It is a bit different with disposable ones. Just like the name suggests, disposable masks need to be disposed of and replaced with a brand-new clean one after using for a certain amount of time.
