PROBLEM TO BE SOLVED: To provide a deodorizing filter effectively exerting stable deodorizing performance to phenols, pyridines, and an aldehyde-based gas such as acetaldehyde having a large contribution as an odor component, contained in various odor components, especially much in an odor component of a tobacco smoke smell.SOLUTION: This deodorizing filter contains components (A) and (B), and has a mass ratio between a hydroxyamine compound represented by formula (1) carried in the component (A) and the component (B) of (0.065-7.4):1. The component (A): particles carried with the hydroxyamine compound represented by formula (1) wherein, R1 is H, a C1-5 alkyl group, or a C1-5 hydroxyalkyl group R2 is H, a C1-6 alkyl group, or a C1-5 hydroxyalkyl group and R3 and R4 are each a C1-5 alkanediyl group. The component (B): porus polymer particles obtained by copolymerizing monomer components containing (B1) a crosslinkable vinyl monomer and (B2) a vinyl monomer having a nitrogen-containing aromatic ring.COPYRIGHT: (C)2012,JPO&INPIT【課題】種々の臭気成分、特にタバコ臭の臭気成分の中に特に多く含まれ、臭い成分として寄与の大きいアセトアルデヒド等のアルデヒド系ガス、ピリジン類、フェノール類に対して効果的に安定した消臭性能を発揮する消臭フィルターの提供。【解決手段】成分(A)及び(B)を含有し、成分(A)中に担持される式(1)で表されるヒドロキシアミン化合物と成分(B)との質量比率が(0.065~7.4):1である消臭フィルター。成分(A):式(1)で表されるヒドロキシアミン化合物を担持させた粒子〔R1はH、C1-5アルキル基又はC1-5ヒドロキシアルキル基。R2はH、C1-6アルキル基又はC1-5ヒドロキシアルキル基。R3及びR4はC1-5アルカンジイル基。〕成分(B):(B1)架橋性ビニルモノマー及び(B2)含窒素芳香環を有するビニルモノマーを含むモノマー成分を共重合して得られる多孔質ポリマー粒子【選択図】なし
