<p>PURPOSE:To enable a room air to be simply and efficiently cleaned, by installing filters, in which an activated charcoal, a removal agent of NO2 consisting of the respectively specific composite, and an oxidation catalyzer of CO are used, to air passage of the ventilator to inside a room of the automobile. CONSTITUTION:In an air passage 11, arranged with a blower 7 provided and capable of raising a temperature by utilizing a unit of the engine, are arranged a filter 8, using an activated charcoal, a filter 9, using a removal agent of NO2, and a filter 10, using an oxidation catalyzer of CO. And the removal agent of NO2 is made by a mixture kneaded molding among alkaline and cement material and powdery activated charcoal, and the oxidation catalyzer of CO is made by a catalyzer where palladium and more than one kind selected from platinum, rhodium, ruthenium are simultaneously or palladium is singly supported to the carrier molded by mixture kneading alkaline and cement material and powdery activated charcoal. In this way, CO oxidation catalyzer can be raised a temperature by especially utilizing a hot air and its CO removal performance can be improved.</p> |
