The disclosed ventilating air cleaner comprises: a housing having an indoor-side intake/discharge hole and an outdoor-side intake/discharge hole; an air cleaning filter provided inside the housing, and capable of cleaning air when air that flows in a circulating direction passes therethrough and reclaiming air when air that flows in a reverse direction passes therethrough; and a ventilating portion provided inside the housing, and generating a flow of air that passes through the air cleaning filter. The ventilating portion generates a flow of air such that air passes through the air cleaning filter in the circulating direction during indoor ventilation and air passes through the air cleaning filter in the reverse direction during filter reclaiming.
