PURPOSE: A filter constitution of air filter is provided, which can improve the efficiency of deodorizing a filter (3) by enlarging the contact area of air by attaching activated carbon (AC) directly to the non-woven fibers instead of mixing the AC with a bonding agent, so that the filter also can improve efficiency of air purifier. CONSTITUTION: The system comprises the followings: (i) a main body that has an inlet hole at side center and outlet hole at the top, and is partitioned by a separation wall; (ii) a motor and a fan installed at the discharge side of the partition wall; (iii) a filter (3) that is installed in a fixing flange at the suction side of the partition wall and is wrapped by a non-woven fiber case (3c) and a case (3d); (iv) a dust collecting filter (3a) set in the case at the suction side; and (v) an activated carbon (31b) set in the filter case at the discharge side for deodorizing bad-smelling gas.
