<p>An air filter (1) capable of improving a combustion efficiency of the engine of a vehicle. A functional film (5) comprising a dispersion of particles of a silicon mineral and yttrium, barium and cerium in a film forming resin laminated on a metallic substrate (4) and the resultant laminated transit member (3, 7, 8, 9) is punched to form a multiple through-holes. The so formed laminated member constitutes a transit member (3, 7, 8, 9). The transit member (3, 7, 8, 9) is incorporated into a known filter body (2) to thereby manufacture the air filter (1). Since the conventional filter body (2) is combined with the transit member (3, 7, 8, 9), dirt or contaminants in the air are removed by the filter body (2). Since on passage through the transmit member (3, 7, 8, 9), air is activated by the action of a wave-generating sintered product contained in the functional film (5) in the form of particles. The air which has been cleaned and activated is fed into the engine. This eventually leads to an improvements of the combustion efficiency of the engine. <IMAGE></p> |
