摘要
The present invention relates to a filter that exhibits an adsorption behavior that compensates for the rapid reduction of the adsorption rate of activated carbon fibers by an adsorption powder having a lower adsorption rate than activated carbon fibers while leading the initial adsorption of harmful gases by activated carbon fibers, and to a method for manufacturing the same. . The method of manufacturing a filter includes a first step of laminating activated carbon fibers (b) and fibrous binders (c) on a lower surface web (a) in order; A second step of forming a bulky fibrous layer (c-1) from a fibrous binder (c) while needle punching the laminate (1) of the first step to bond; A third step of dispersing and filling the adsorption powder (d) on the bulky layer (c-1); And a fourth step of optionally laminating the top web (e).
