Abstract
A three-dimensional, photocatalytic filter apparatus is constituted by (a) a flow path means through which a fluid stream containing pollutants passes; (b) a plurality of porous filter plates each carrying a photocatalyst for decomposing the pollutants; (c) a light source; and (d) at least one support member for arranging each porous filter plate in a path of the fluid stream in the flow path means, at such a three-dimensional position that each porous filter plate is inclined relative to both the fluid stream and the light source, to achieve sufficient contact with the pollutants and sufficient exposure to the light source.
