<p>PROBLEM TO BE SOLVED: To purify air by forming a filter used for an air purifying by putting a chemical for removing aldehydes on it as a carrier to efficiently remove them. SOLUTION: In the filter used by being incorporated in the air purifier, the chemical for removing the aldehyde is carried on the carrier. In such a case, as the chemical for removing the aldehyde, one selected from ammonium sulfate, polyaryl amine hydrochloric salt, EDTA.2Na, triethanol amine, pyridine, amide sulfuric acid, dimethyl hydantoin, casein, urea, thiourea, sodium caseinate, amino guanidine sulfate, hexamethylene tetramine, guanidine nitrate is used. And as the carrier, one selected from activated carbon, calcion silicate, zeolite, cellulose, an ion exchange resin and an alkaline pH adjuster is carried with the chemical for removing aldehyde.</p> |
