PROBLEM TO BE SOLVED: To provide a tobacco odor removing filter which has a great deodorant effect against tobacco odor, is low in pressure loss, and exhibits a superior performance of durability.SOLUTION: This filter includes: an inorganic silicon compound carrying a polyamine compound, and a hydrazide compound, both of which are adhered to a nonwoven fabric through a binder resin, wherein the filter has a pressure loss of 3 to 30 Pa per cm of filter thickness under a condition of a wind velocity of 1.0 m/sec for passing through the filter, when measured according to the JIS B9908. It has been found that the tobacco odor removing filter thus obtained has a great deodorant effect against tobacco odor, is low in pressure loss, and exhibits a superior performance of durability.COPYRIGHT: (C)2013,JPO&INPIT【課題】タバコ臭に大きな消臭効果があって、しかも圧力損失が低く、耐久性能の優れたタバコ臭除去フィルターを提供する。【解決手段】不織布にポリアミン化合物を坦持した無機ケイ素化合物と、ヒドラジド化合物とをバインダー樹脂を介して固着させ、JIS B9908規格で測定した圧力損失が、フィルターの通過風速が1.0m/秒の条件下で、フィルターの厚さ1cm当たり3~30Paとすることで、タバコ臭に大きな消臭効果があって、しかも圧力損失が低く、耐久性能の優れたタバコ臭除去フィルターが得られることを見出した。【選択図】なし
