PROBLEM TO BE SOLVED: To provide an aldehyde elimination filter that is thin, lightweight, and comparatively inexpensive, and has a great deodorization effect on aldehydes, low pressure loss, and excellent duration performance.SOLUTION: An aldehyde elimination filter is a filter where silica gel and a hydrazide compound are fixed to at least a part of a foaming base material having continuous pores, and pressure loss measured by JIS B9908 standard is 3-30 Pa per centimeter thickness of a filter under a condition that the passage wind speed of the filter is 1.0 m/s.COPYRIGHT: (C)2014,JPO&INPIT【課題】厚さが薄く、軽量、比較的安価で、アルデヒ類に大きな消臭効果があって、しかも圧力損失が低く、耐久性能の優れたアルデヒド除去フィルターを提供することを目的とする。【解決手段】連続気孔を有するフォーム基材の少なくとも一部にシリカゲルとヒドラジド化合物を固着させ、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であることに特徴のあるアルデヒド除去フィルター。【選択図】なし
