(57) [Summary] (Modified) [Objective] To provide an adsorbent having a simple structure and exhibiting good adsorption performance for both malodorous components of aldehyde and ammonia. Further, the present invention provides an air cleaning filter unit which is excellent in aldehyde and ammonia adsorption performance, has a small pressure loss, and has a low manufacturing cost. [Configuration] 1. Ammonia and aldehyde adsorbents, characterized in that 3 to 50% of aminobenzenesulfonic acid is impregnated on an activated carbon material having a pore volume of 0.25 to 1.1 cc / g with a pore diameter of 10 to 100 angstrom. . 2. The volume of pores having a pore diameter of 10 to 100 angstroms is 0.25 to 1.1 cc / g, and activated carbon fibers impregnated with 3 to 50% by weight of aminobenzenesulfonic acid are electro-planted on a porous substrate. Air purification filter unit. |
