The present invention relates to a filter support. More particularly, the present invention relates to a dry non-woven fabric thermally-bonded filter support having a structure capable of enhancing filter life by reducing the pressure loss of a filter due to enhanced environmental resistance in harsh environmental conditions. The filter support comprises: a first dry non-woven layer; and a second dry non-woven layer, wherein the first dry non-woven layer has better air permeability than the second dry non-woven layer.
본 발명은 필터지지체에 관한 것이며, 더욱 상세하게는 가혹한 환경조건에서의 내환경성 개선에 의한 필터의 압력손실을 개선시켜 필터수명을 증가시킬 수 있는 구조를 갖는 건식부직포 열융착 필터지지체에 관한 것이다.
