PURPOSE: An air sterilizing apparatus is provided to reduce time for creating purification ions by decomposing ozone using an ozone lamp.CONSTITUTION: A pre-filter(20) filters dust included in air-flow in an indoor space. An inhalation fan is rotated for forcibly discharging and inpouring the air. A far infrared lamp(50) purifies the inhaled air. A photo catalysis filter(70) is formed between an elvan filter(60) and an outlet port(13). An inlet port(12) is formed in one end of a body(11). The outlet port is formed in other end of the body. An ultra violet ray lamp radiates the ultra violet ray of 253.7nm.COPYRIGHT KIPO 2013실내의 오염된 공기를 살균 정화하는 장치
