The invention relates to a dust-proof cool-type mask which is composed of a mask body and fixing bands fixed at the two ends of the mask body. The mask body comprises an outer surface layer, an inner surface layer and a filter layer arranged between the outer surface layer and the inner surface layer; the outer surface layer is made of cotton fabric, the filter layer is composed of non-woven cloth and an activated carbon fiber filter screen clamped by the non-woven cloth, and the inner surface layer is made of blend fibers. The dust-proof cool-type mask is characterized by further comprising cool-keeping layers which are located between the outer surface layer and the filter layer or located between the inner surface layer and the filter layer; each cool-keeping layer is composed of a cool-keeping inner layer, a cool-keeping outer layer and cool-keeping agents which are packaged inside the cool-keeping inner layer and the cool-keeping outer layer through packaging materials, and the areas of the cool-keeping layers are smaller than the area of the outer surface layer, the area of the inner surface layer and the area of the filter layer. By means of the dust-proof cool-type mask, when the temperature is high in summer, the stuffiness feeling produced when a person wears a mask can be eliminated, and meanwhile good air permeability and a good filtering effect are achieved; a cool feeling can be brought for the person wearing the mask when the environment temperature is too high, and meanwhile the good air permeability and the good filtering effect on tiny particles are maintained.
