Abstract: The present invention relates to a non-electrical demisting method, including a mirror and a mirror frame covering on an outer periphery of the mirror frame, wherein the mirror is fixed to inner periphery of the mirror frame. On the outer periphery of the mirror frame is fixed with a heat-conducting element that serves to conduct heat to the mirror, so as to increase temperature of the mirror surface, and thus moistures on the mirror surface can be demisted.
