Disclosed herein is an oven range with a filter member improving the purification efficiency of toxic gas in a cavity. The filter member includes a plurality of sections inclined upward or downward with respect to one another and interconnected, with curves irregularly formed along the sections. Accordingly, since the toxic gas being discharged through the filter member is dispersed, entangled and mixed by the irregular curves of the filter member, a reaction time between the toxic gas and a catalyst coating the filter member is increased, thereby improving the purification efficiency.
