う問題があった。In the conventional air purifier shown in FIG. 3 as described above, a deodorizing filter using only powdered activated carbon as shown in FIG. 4 or only granular activated carbon as shown in FIG. 5 is used. Had used a deodorizing filter. At this time, if a deodorizing filter using only powdered activated carbon is used, there is an advantage that the adsorption speed is fast because the activated carbon has a small particle size and a large surface area. There is a problem that is easily released again. In addition, when a deodorizing filter using only granular activated carbon is used, there is an advantage that the amount that can be adsorbed is large.However, since the activated carbon has a particle diameter of about 1 mm or more and the surface area cannot be increased dramatically, the adsorption speed is reduced. There was a problem that a large amount of activated carbon had to be used to increase the speed.

Although the two deodorizing filters are used, the deodorizing filter using only the powdered activated carbon as shown in FIGS. 4 and 7 has an advantage that the adsorption speed is high as described above. However, there is a problem that the amount that can be adsorbed is small and the odor is quickly saturated and the odor is easily released again. In addition, in order to insert two deodorizing filters, it is necessary to provide individual storage sections or mounting sections. Furthermore, the foamed gas-permeable activated carbon filter in which powdered activated carbon is bonded to the foamed gas-permeable sheet has a problem in strength that it is easily broken.

う問題があった。In the conventional air purifier shown in FIG. 3 as described above, a deodorizing filter using only powdered activated carbon as shown in FIG. 4 or only granular activated carbon as shown in FIG. 5 is used. Had used a deodorizing filter. At this time, if a deodorizing filter using only powdered activated carbon is used, there is an advantage that the adsorption speed is fast because the activated carbon has a small particle size and a large surface area. There is a problem that is easily released again. In addition, when a deodorizing filter using only granular activated carbon is used, there is an advantage that the amount that can be adsorbed is large.However, since the activated carbon has a particle diameter of about 1 mm or more and the surface area cannot be increased dramatically, the adsorption speed is reduced. There was a problem that a large amount of activated carbon had to be used to increase the speed.

Although the two deodorizing filters are used, the deodorizing filter using only the powdered activated carbon as shown in FIGS. 4 and 7 has an advantage that the adsorption speed is high as described above. However, there is a problem that the amount that can be adsorbed is small and the odor is quickly saturated and the odor is easily released again. In addition, in order to insert two deodorizing filters, it is necessary to provide individual storage sections or mounting sections. Furthermore, the foamed gas-permeable activated carbon filter in which powdered activated carbon is bonded to the foamed gas-permeable sheet has a problem in strength that it is easily broken.
