PURPOSE: A deodorizing filter for removing odor from a food waste disposal system is provided to offer good deodorization efficiency with durability under environment in which moisture is contained, and to process a support with chemicals. CONSTITUTION: A deodorizing filter(100) includes a first layer(101) and a second layer(102). The first layer consists of a mineral support in which at least one or more oxidized metal materials are impregnated, which is selected from potassium dichromate, sodium permanganate, potassium dichromate, and sodium bichromate. The second layer is laminated on the top of the first layer. An inorganic porous support is activated charcoal or charcoal. The mineral support is alumina oxide, oxidation silica, zeolite, bentonite, limestone, sepiolite and pearlite.
