The invention belongs to the field of air purification, and particularly relates to a dustproof filtering air filter for an automobile. The dustproof filtering air filter for the automobile comprises an air suction structure, a filtering structure and an induction structure, wherein an air inlet is formed in the inner wall of the filter; a first fixing support frame is fixedly connected onto the inner wall of the filter; the first fixing support frame is connected with a first air suction fan through a first rotating shaft; a pipeline air inlet is formed in the front end of the filtering structure; a filtering element is fixed in the filtering structure; a spiral filtering pipeline is connected to the outer side of the filtering element; a first U-shaped pipe is connected to the lower end of the filtering structure; filtering oil is contained in the first U-shaped pipe; a second U-shaped pipe is connected to the other side of the first U-shaped pipe; an air outlet is connected to the other side of the second U-shaped pipe; a second air suction fan is arranged on the inner wall of the air outlet; a second fixing support frame is fixedly connected to the inner wall of the air outlet; an inductor is arranged on the second fixing support frame; the second fixing support is rotationally connected with the second air suction fan through a second rotating shaft; and an opening and closing opening is formed in a valve. The dustproof filtering air filter for the automobile solves the problems of big size and poor filtering effect of a conventional filter.
