Disclosed is a high efficiency photocatalyst filter. The high efficiency photocatalyst filter comprises: a housing including a flow channel formed inside, wherein a fluid passes through the flow channel a screw rotating body arranged in the flow channel to be rotatable a photocatalyst layer formed on the surface of the screw rotating body and a light source module emitting light to the photocatalyst layer. The high efficiency photocatalyst filter has improved sterilization and deodorization effects by actively inducing photocatalytic reactions.COPYRIGHT KIPO 2016고효율 광촉매 필터에 대한 발명이 개시된다. 개시된 발명은: 유체가 통과하는 유로가 내부에 형성되는 하우징과 유로에 회전 가능하게 구비되는 스크류회전체와 스크류회전체의 표면에 형성되는 광촉매층 및 광촉매층에 광을 조사하는 광원모듈을 포함한다.
