PROBLEM TO BE SOLVED: To improve deodorizing performance by combining an adsorption material having adsorption function with a deodorizing material having adsorption function and catalytic function and using both jointly. SOLUTION: This filter is formed by inserting a cushiony non-woven fabric 5 between non-woven fabrics 3, 4 to be the outer layers of the front and rear both surfaces and capturing a material prepared by mixing a granular activated carbon 6 with a similar granular two kinds of deodorizing materials 7, 8 on the cushiony non-woven fabric 5. One of the deodorizing materials 7, 8 is a metallic ferrocyanin compound deodorizing material and another is a graft polymerization deodorizing material. |
