Abstract (en)
The present invention relates to a dust mask. The dust mask of the present invention comprises: a mask main body in a shape enclosing the nose and mouth areas; a ring-shaped eyepiece, the outer perimeter of which is bound to the periphery of the main body; and a shape retainer detachably provided on an inner surface of the main body. In particular, the shape retainer is a thin film which is not pervious to fluid and which has an intake hole and a discharge hole, an outer perimeter contacting a joining portion between the main body and the eyepiece, and a contactless passage connected from the end of the outer perimeter to the intake hole by means of a plurality of projecting guides radially formed on a surface thereof. The dust mask of the present invention does not exhibit loss of filtering ability of the mask main body caused by contact. Thus, the dust filtering efficiency of the dust mask is significantly improved over conventional masks.
