摘要： A fluid cleaning filter is composed of a complex comprising a pleat-forming body (2) having polyurethane foam (2a) of three-dimensional reticular skeleton construction and molded in pleat form, and an activated carbon containing layer (3). The complex is molded in substantially cylindrical form. The surface of the polyurethane foam (2a) opposed to the activated carbon containing layer (3) is provided with a filter layer (2b) made of fiber. The fiber of the filter layer (2b) may be treated for electrification. The fluid cleaning filter has high dust-collecting efficiency and high deodorization efficiency even under high-speed wind conditions.

摘要： A fluid cleaning filter of the present invention consists of a composite matrix composed of a pleated substrate 2 configured into a pleated shape and an active. carbon-containing layer 3, wherein the pleated substrate 2 is made of polyurethane foam 2a having a three-dimensional network skeletal structure, and the composite matrix is configured into a cylindrical shape. A filtering medium layer 2b made of fibers is formed on the surface of the polyurethane foam 2a facing the active carbon-containing layer 3. The fibers of the filtering medium layer may be electrostatically charged. The fluid cleaning filter exhibits good efficiency of dust collecting and deodorization even when a fluid flows through the filter at high rate.
