PURPOSE:To remove smell such as nitrogenous compound, etc., by using a paper containing zeolite as a carrier on which at least one kind selected out of aromatic amino acid, aromatic amino acid salt, a copper compound or an iron compound is carried. CONSTITUTION:A paper containing zeolite is used as an adsorption carrier, on which at least one kind selected out of aromatic amino acid or aromatic amino acid salt group (for example, o-, m- or p- amino beonzoate), a copper compound (for example, copper chloride) or an iron compound (for example, ferric chloride) is carried. Said porous deodorizing filter exhibits superior removing performance for major components of smells of nitrogenous compd. generated in the living environment such as ammonia, trimethylamine or the like, smell of sulfur compd. such as methyl mercaptan, hydrogen sulfide or the like, and smell of lower aldehyde group such as formaldehyde or acetoaldehyde. |
