| Zusammenfassung: | Disclosed is an air purification filter: having a plurality of first protrusion parts arranged on a film part, which is made from a polymer synthetic resin, in the direction orthogonal to the flow direction of air, and a plurality of second protrusion parts arranged in the direction parallel to the flow direction of air, wherein the first and second protrusion parts are regularly formed; having a ventilation path formed by winding the film part; and formed such that the flow direction of the air is formed along the longitudinal direction of the film part, thereby reducing pressure loss and improving dust collection efficiency. |
