じないことが要求される。[0003] However, in the case of the adsorption filter in which the container is filled with the adsorbent as described above, the adsorbent must be discharged from the container when the adsorbent is replaced, and the container must be filled with a new adsorbent. Replacement work is troublesome. Furthermore, when the adsorbent is exchanged, there is a problem that fine powder of the adsorbent is scattered and the environment is impaired. Particularly, in a clean room in a semiconductor manufacturing plant, the generation of fine powder is strictly prohibited because the function of the clean room is impaired, and it is required that the generation of fine powder does not occur when the adsorbent is replaced.

来の吸着性能が発揮されなくなるという問題がある。As a method for preventing the generation of fine powder at the time of replacing the adsorbent, a filter molded article in which a powder binder is mixed with the adsorbent and heated to bond the adsorbents by welding of the powder binder is placed in a container. It has been proposed to contain. However, according to this method, since the surface of the adsorbent is covered with the powder binder, there is a problem that the original adsorption performance of the adsorbent cannot be exhibited.

Furthermore, depending on the field of use of the filter, there is a need to have an adsorbent property for an alkaline gas such as ammonia or an acidic gas such as hydrogen sulfide. In addition, a neutralizing agent made of an alkaline chemical such as potassium carbonate is impregnated, and an alkaline gas or an acidic gas is adsorbed and removed by a neutralization reaction of the neutralizing agent. However, in such a case, the binding strength of the powder binder may be reduced due to the presence of the neutralizing agent, and the filter molded product may be easily broken.
