Abstract
A deodorizer includes: a body case having an inlet and an outlet opening outward and having an air duct that provides communication between the inlet and the outlet; a blowing fan included in the body case, for introducing indoor air into the air duct extending from the inlet to the outlet; deodorizing means provided in a middle of the air duct, through which the introduced air can pass; heating means placed to face at least a partial region of the deodorizing means, for heating the deodorizing means at 200° C. or less; and a controller for controlling operations of the blowing fan and the heating means. The deodorizing means includes, on a carrier, an adsorbent that does not oxidatively decompose an adsorbed material, a catalyst component that oxidatively decomposes the adsorbed material, and a rate of conversion of alcohol into acetic acid by the catalyst component is 15% or less on average across the entire deodorizing means.
