<p>PURPOSE:To provide an air filter with long life capable of removing odor and which is used for an air cleaner. CONSTITUTION:On the surface and back of an electrostatic filter material 12 a pair of electrodes 1, 2 having many ventilating holes are provided. A pair of the electrodes 1, 2 are fixed by a set of external frames 15, 16 and a pair of the electrodes 1, 2 or either of them is covered with a room temp. deodorizing material and DC voltage is applied to a pair of the electrodes 1, 2.
