PURPOSE:To prevent mold from propagating for a long period by mixing a mold-resist agent consisting of ether compounds or benzimidazole compounds to fiber material forming filter material. CONSTITUTION:An air filter 1 consists of a filter 2 made of polypropylene resin and a frame 3 made of acrylonitrile.butadinene.styrene resin. The mold- resist agent is mixed to the fiber of the filter 2 in the range of 0.2-2.0wt.% the whole weight of fiber. As for the mold-resist agent, benzimidazole compounds or ether compounds are used. As for benzimidazole compounds, for instance, 2.methoxycarbonylaminobenzimidazole is used, and as for the ether compounds, for instance. 2.4.4.trichlorohydroxyether is used. As for the mold-resist processing, for instance, the mold-resist agent may be mixed with the pigment used for coloring the resin material.
