<P>PROBLEM TO BE SOLVED: To enable an efficient decomposition of air with an even air stream passing through a photocatalyst filter unit by acquiring the optimum velocity attributed to substances to be decomposed securing an effective area of a filter with a photocatalyst carrier without increase in size of the apparatus relating to a cleaner which takes in a large amount of air using a photocatalyst to be discharged outside a chamber immediately being lowered down below an exhaust reference value. <P>SOLUTION: In an air cleaner with a photocatalyst filter unit 10 which is disposed with a plurality of long and provided with photocatalyst carrier filters in parallel with each other so as to hold the ultraviolet ray sources 12 therein, the photocatalyst filter unit 10 is provided inclined to the air flow 7 flowing in and the long and thin ultraviolet ray sources 12 are made orthogonal to the air flow 9 along its length orthogonal to the inclination of the photocatalyst filter unit 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
