Adsorption filter

The present invention relates to an adsorption filter comprising an activated carbon and a fibrillated fibrous binder, the activated carbon having a volume-based cumulative particle size distribution of 0% particle size (D0) of 10 [mu] m or more and a volume-based cumulative particle size distribution of 90-200 [mu] m, the volume-based cumulative particle size distribution of 50% particle size (D50), the fibrillated fibrous binder having a CSF value of 10-150 mL, the fibrillated fibrous binder is contained in an amount of 4-8 parts by mass per 100 parts by mass of the activated carbon. 本发明涉及一种吸附过滤器，其包含活性炭和原纤化纤维状粘合剂，所述活性炭的体积基准的累积粒度分布中的0％粒径亦即D0为10μm以上，且体积基准的累积粒度分布中的50％粒径亦即D50为90～200μm，所述原纤化纤维状粘合剂的CSF值为10～150mL，相对于100质量份所述活性炭，包含4～8质量份所述原纤化纤维状粘合剂。
