DEODORIZING FILTER AND AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide an air conditioner capable of easily judging an replacement time of a deodorizing filter and an indoor odor concentration. SOLUTION: A deodorizing life of the deodorizing filter 1 is judged by the color change of the deodorizing filter itself by forming the deodorizing filter 1 with an adsorbent 4 for adsorbing the odor component in the air and a color- changing agent 5 which changes color by the reaction with the odorous component.
