     	이를 위한 본 발명에 따른 멀티필터는 먼지 여과층과 탈취여과층으로 이루어진 얇은 슬라이스 구조를 갖는바, 먼지 여과층은 1차 PP 부직포, 2차 PP MELT BLOWN 부직포, 3차 PET 부직포로 구성되고, 탈취여과층은 나노실버 카본 코팅부직포로 구성됨을 특징으로 한다. 
     	또한 본 발명에 따른 융모형 집진구조는 공급롤러(7)로부터 권취롤러(5)로 권취되는 멀티필터(16)를 융모형(지그재그)으로 이동되도록 한 다수의 구동롤러(10)및 아이들 롤러(11)와; 구동롤러(10)를 동일한 방향으로 회전시켜 융모형(지그재그)으로 이동되는 롤형 멀티필터(16)가 공급롤러(7)로부터 풀려져서 권취롤러(5)에 감겨지도록 모터(12)의 구동력을 전달하는 체인(13)과 벨트(13a) 및 스프라켓(14)과 풀리(15)를 구비한 구동수단으로 구성됨을 특징으로 하며, 본 발명에 있어서, 멀티필터를 통해 정화된 공기가 흐르는 부위에 자외선 램프를 장착하는 것이 바람직하다. 
     	따라서 본 발명은 종래의 에어필터가 갖는 기본적인 여과기능 외에 낮은 압력손실에도 고효율을 낼 수 있는 탁월한 포집효율과 탈취여과층에서 발휘되는 살균, 항균, 탈취등의 복합적인 기능을 갖춘 멀티필터와 이를 융모형 집진구조로 설치함으로써 여과면적이 극대화되어 먼지 등을 효율적으로 포집할 수 있고, 종래에 사용되는 롤형 에어필터보다 얇아 많이 감길 수 있으므로 빈번한 교체에 따른 추가 구매비용과 인건비등을 절약할 수 있다. 
     그리고 광촉매에 의한 살균과정까지 이뤄져 보다 양질의 공기를 실내에 공급할 수 있다.
