Description of the Related Art A deodorizing filter in which paper is processed into a honeycomb shape and an adsorbent such as activated carbon is attached to the surface thereof, or a deodorizing filter formed in a honeycomb shape after adhering or supporting activated carbon on the surface or inside of the paper in advance. Is known. Since these deodorizing filters are inexpensive and lightweight, they are used in air purifiers and the like, but they have a drawback that the adsorbent weight per unit volume is small and the period of use is short. Further, when the gas to be removed contains gases such as ammonia, acetaldehyde, hydrogen sulfide, acetic acid, etc., there is also known a method of improving the removal ability by supporting various chemicals on an adsorbent such as activated carbon. . However, although carrying the chemical improves the removal ability for the gas to be removed, there is a problem in that the removal performance for other gases deteriorates. For example, activated carbon loaded with an inorganic acid has a higher ability to remove ammonia, but lowers the ability to remove organic substances such as acetic acid and valeric acid. Further, when a plurality of chemicals are attached to one adsorbent, the removal performance tends to be lower than when a single chemical is attached.

性能が得られることが明らかとなった。As is apparent from [Table 1], Comparative Example 2 in which three kinds of chemicals, phosphoric acid, morpholine and potassium iodide, were carried on a honeycomb structure having a deodorizing ability, was prepared. Although the number of acetaldehyde durables increased compared to the impregnated comparative example 1, the number of durable ammonias and the number of durable acetic acids decreased. On the other hand, in Example 1 in which different chemicals were loaded on the honeycomb structure and the activated carbon, the number of durability was increased for all the components. Further, in Comparative Example 3 in which the honeycomb structure having no deodorizing ability was filled with activated carbon, the number of durable tires was reduced as compared with Example 1. From this, it became clear that by using the deodorizing filter having the structure of the present invention, higher removal performance than that of the conventional one can be obtained.

Further, by using different kinds of adsorbents in the honeycomb structure and the absorbent filled in the cells, or by carrying different kinds of chemicals,
It is possible to deal with various types of gas to be removed. Further, since the paper is used as a material and has resistance to impact, it is not damaged or collapsed even when installed in a place where vibration is severe, for example, in an automobile.
