ABSTRACT:
The invention provides a filter element exhibiting an excellent deodorizing and adsorbing function with low pressure drop, as well as to a method for its manufacture and a filter using the element. The filter element is manufactured by coating a base fabric with an adhesive and allowing the fabric to move in an electrostatic field formed by a high voltage generating device to allow pulverized adsorbent powder with a specific mean particle size and standard deviation to electrostatically adhere to the base fabric surface. The filter element can also be manufactured by dispersing a pulverized adsorbent powder on the surface of a base fabric comprising heat-fusible fibers, and then partially fusing the heat-fusible fibers by heating to attach them to the adsorbent powder and allow the adsorbent powder to adhere to the base fabric surface.
