<p>PROBLEM TO BE SOLVED: To provide a deodorizing and dust collecting filter free from the re-diffusion of odor even when a power switch is turned off and a photocatalyst does not operate, and cause the filter to effectively and stably display a deodorizing and dust collecting function. SOLUTION: Regarding dust and odor from an air intake 7, the odor is removed with a deodorizing net 8 carrying phthalocyanine (chelate compound of transition metal), and dirt or dust passing through the net 8 is removed with a (hepa) filter 6 having high efficiency for particle removal. Also, residual odor is removed with a photocatalyst filter 3 (honeycomb filter carrying titanium oxide and porous adsorbing material) exposed to irradiation from an ultraviolet lamp 4. In this case, an odor molecule before decomposition is further removed with a honeycomb filter 2 carrying phthalocyanine.</p> |
