The present invention relates to an air conditioning filter system, and more specifically, a main body, a front panel coupled to an open front side of the main body and provided with an intake port to allow air to flow into the interior of the main body, and the air introduced through the intake space to the indoor space. In the air conditioning filter system comprising an outlet for discharging to, a blower fan for forcibly circulating air inside the body, and an air purifying unit for purifying circulated air, wherein the air purifying unit is air from the air inlet to the air outlet. A photocatalyst filter provided in the passage； A filter support on which the photocatalytic filter is mounted on one side and supports the mounted filter； A plurality of UV lamps having different outputs irradiating UV light to the photocatalyst filter； An odor sensor detecting the degree of odor in the air passage； An ultraviolet lamp control device for operating the ultraviolet lamp based on an on / off operation time variable according to the detected odor level so that the plurality of ultraviolet lamps do not operate simultaneously； And a desorption dust chamber in which dust particles detached from the photocatalyst filter are dropped and deposited, and the filter support includes an outer frame disposed along an outer circumferential surface； A plurality of bands fixed to both ends of the outer frame and arranged in a mesh shape； And a piezoelectric body that generates ultrasonic waves arranged at the intersections of the bands, thereby continuously removing and deodorizing and deodorizing and attaching dust (particulate matter) attached to the filter, thereby increasing the life of the filter, thereby increasing the filter replacement cycle. It relates to an air conditioning filter system that can significantly improve the.본 발명은 공조필터시스템에 관한 것으로서, 보다 상세하게는 본체, 상기 본체의 개방된 전면에 결합되어 본체의 내부로 공기가 유입되도록 하기 위한 흡입구가 구비된 전면패널, 흡입구로 유입된 공기를 실내공간으로 배출하기 위한 배출구, 상기 본체의 내부에 공기를 강제순환하기 위한
