PROBLEM TO BE SOLVED: To provide a composite filter member which can remove malodor and harmful substances such as bacteria by the photocatalytic performance of a photoreactive semiconductor and by the adsorptivity of an adsorbent and which maintains excellent performance of removing harmful substances even under the condition of high humidity by the dehumidifying performance of at least one kind selected from a group of silica gel, allophane, sepiolite and zeolite. SOLUTION: The composite filter member is obtained by combining and integrating a deodorizing filter containing at least a photoreactive semiconductor and an adsorbent with a dehumidifying filter containing at least one kind selected from a group of silica gel, allophane, sepiolite and zeolite. |
