| description | Provided is a filter medium. A filter medium according to an embodiment of the present invention comprises: a first porous support body which has been electrostatically treated; and a nanofiber web which is disposed on one surface of the first support body and formed by accumulating nanofibers. Accordingly, excellent air filtering efficiency is obtained even for fine dust of PM 2.5 or below, and furthermore, deterioration in air filtering efficiency may be prevented or minimized even when usage is extended for a long period time. Therefore, the filter medium and the composite filter according to the embodiment of the present invention can be widely utilized as media of filters for various air filtering devices.
필터여재가 제공된다. 본 발명의 일 실시예에 따른 필터여재는 정전 처리된 다공성의 제1지지체 및, 상기 제1지지체의 일면 상에 배치되고, 나노섬유가 축적되어 형성된 나노섬유웹을 포함하여 구현된다. 이에 의하면, PM 2.5 이하의 미세먼지에도 매우 우수한 공기 여과효율을 가지며, 이에 나아가 사용시간이 장시간 연장되는 경우에도 공기여과 성능의 저하가 방지 또는 최소화될 수 있다. 따라서, 본 발명의 일실시예에 따른 필터여재 및 복합필터는 각종 공기여과 장치용 필터류의 여재로써 널리 응용될 수 있다. |
