Title:
DEODORIZING FILTER
Document Type and Number:
Japanese Patent JP2000079318
Kind Code:
A
Abstract:
To provide a long-life, low-priced deodorizing filter which has a high deodorizing speed, effectively produces a deodorizing effect even in the environmental condition that air flows or is dry, and does not reemit the removed odor molecules.
A deodorizing filter is constituted by holding an odor molecule adsorbing material such as activated carbon and a catalyst consisting of a transition metal chelate compound decomposing and adsorbing the odor molecules, on urethane foam. The odor molecule adsorbing material produced by applying an emulsion adhesive (a water-soluble acrylic adhesive), in which the metal chelate compound is melted, to the surface of the adsorbing material to be thermally cured, is used.
