Products with this configuration have drawbacks such as the filling rate changing due to transportation and vibration, the generation of fine powder and contamination, and the flow path of the processing fluid changing, making it impossible to achieve the initial purification performance.

増やすと圧損が増加するなどの欠点を有していた。In order to compensate for these drawbacks, various filter processing methods have been proposed in recent years. In the filter shown in FIG. 8, particles of an adsorbent 32 are directly sprinkled on a nonwoven fabric 31 made of thermoplastic resin, and the filter is bonded by thermocompression. In addition, the one shown in FIG. 9 has a structure in which an adsorbent 32 is bonded to a non-woven fabric, a three-dimensional mesh elastic sheet 33, etc. using a rubber-based or vinyl-based adhesive. Of these, the former has drawbacks such as a weak bonding force between the adsorbent 32 and the nonwoven fabric 3, and the components attached to the adsorbent deteriorate due to heat during heating. Also, the air pressure drop was high. In the latter case, since adhesives are used, solvents and solutes have a considerable effect on the adsorption capacity of the adsorbent, resulting in a decrease in adsorption capacity, uneven distribution of the adsorbent, and an increase in the amount of adsorbent used. Increasing the pressure loss has the disadvantage of increasing pressure loss.

There was a drawback that the fiber basis weight of the nonwoven fabric 13 had to be increased, resulting in an increase in pressure loss. Furthermore, although the pressure drop is relatively low against laminar air flows, there is also the problem that the pressure drop increases due to lateral flows and turbulent flows that occur in actual use, colliding with the walls of the honeycomb.
