<p>A filter element which satisfies the relationship that 0 ≤ A ≤ 1.1 m B + C, and m = 0.28 - 0.0005 D50, with the provis o that 0 < C ≤ 15, wherein D50 = 50 % particle diameter of an adsorbent, B = the amount adhered, A = a pressure loss of a filter as measured at room temperature and under an air flow rate of 1 m/sec, and C = a pressure loss of a base fabric having been coated with an adhesive and dried; a suitable method for manufacturing the filter element which comprises coating a base fabric with an adhesive, allowing the resultant fabric to move in an electric field formed by a high voltage generating device to allow an adsorbent powder to adhere electrically to the surface thereof, or comprises dispersing an adsorbent powder on the surface of a base fabric comprising heat-fusible fibers, and then fusing the fabric partly by heating, to allow the adsorbent powder to adhere; and a filter using the filter element. The filter has excellent deodorizing function and adsorbing performance capabilities, and also exhibits a reduced pressure loss.</p> |
