<p>The present invention relates to an air cleansing filter. More specifically, in the air-cleaning filter, a first and a second vibration piece are partly connected to the surface of a first and a second film which are attached each other and the other parts of the first and the second vibration piece are cut and stacked in the separation thereof, thereby forming slanting-static electricity wings. The air-cleaning filter captures fine dust among air by static electricity caused by the vibration of the first and the second vibration piece wherein air supplied and discharged between the first and the second vibration piece is allowed to vibrate the first and the second vibration piece, thereby making static electricity in a cylindrical-shaped static electricity wings which are arranged. Moreover, in the static electricity wings, the first and the second vibration piece shake according to air flow, thereby generating vibrations; and accordingly, the generation range and contact area of static electricity widen, thus improving efficiency of capturing dust.</p> |
