Japanese Patent JP3594043
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a deodorizing filter used for deodorizing the open air introduced into an air cleaning unit or a vehicle, ensuring a smaller pressure drop and having high deodorizing performance.
SOLUTION: Polyurethane foam having a three-dimensional network skeleton structure is used as the substrate of a filter and deodorant particles are fixed on the substrate with a binder to obtain the objective deodorizing filter having a rugged three-dimensional structure. When a sheetlike dust collecting filter is set on the rugged surface of the deodorizing filter, dust collecting function is imparted while suppressing the increase in pressure drop due to the combination.
