A fold is formed by bending the bent portion outward and upward again, and at the time of use, the central portion of the leading edge of the bent portion is expanded so that it can adhere from the nose to the cheek. (2) The lower part of the mask body is bent, the tip reaches the upper part of the mask, and the left and right sides thereof are sewn to form a filter storage pocket capable of storing a filter therein. It is a hygiene mask that is a feature.

[0011] The second aspect of the present invention is a sanitary mask made of a knitted fabric or a nonwoven fabric. (1) The form of the upper part of the sanitary mask main body is such that the upper part of the mask main body is once bent inwardly downward and then re-formed. A fold is formed by bending the bent portion outward and upward, and at the time of use, the central portion of the distal end edge of the bent portion is expanded to be able to adhere from the nose to the cheek. A) A sanitary mask characterized in that another knitted or non-woven fabric is superimposed on the mask body and a lower portion and left and right sides are sewn to form a filter storage pocket in which a filter can be stored.

A third aspect of the present invention is a sanitary mask in which a filter made of a knitted or woven fabric, a nonwoven fabric, or a breathable sheet impregnated with water and various chemicals is further inserted into the bag portion of the sanitary mask.
