The l 2 O 3 molar ratio is in the range of 1.0 to 2.0 and the diameter is 35
It is an aggregate of hollow spherical fine particles of about 50 Å. Allophane's spherical wall has defects that allow water molecules to enter and exit, and, like silica gel, has a small amount of moisture absorption under low humidity conditions, but has an extremely large amount of moisture absorption under high humidity conditions.

Bornite, shabazite, clinoptilolite, erionite, ferrierite, mordenite, dacuffite, spicy stone are typical natural zeolites, and among these, the amount is large and those commonly used are , Fluorite, clinoptilolite, mordenite. On the other hand, examples of the synthetic zeolite include A-type zeolite, X-type zeolite, and Y-type zeolite. There is no particular limitation on the pore diameter of the zeolite, but considering that the diameter of the water molecule is 2.8 angstroms, the zeolite having a pore diameter of about 3 to 4 angstroms is not affected by the coexisting gas. It is particularly preferable in that only moisture in the air can be selectively adsorbed and removed.

る。Zeolite takes in moisture into pores in the molecule and absorbs moisture, so that it quickly absorbs and desorbs moisture and has a large amount of moisture absorption even under low humidity conditions. However,
In the case of zeolite, the amount of moisture absorption reaches a peak at a relatively low relative humidity, and thus the silica gel, allophane, and sepiolite are superior in the amount of moisture absorption under high humidity conditions.

In addition, as a base for the dehumidifying filter and a means for attaching and fixing silica gel, allophane, sepiolite, and zeolite to the base, the bases and means described in the section of the deodorizing filter can be used in the same manner.
【0037】上記の脱臭フィルタと除湿フィルタを複合

う課題があった。By using an appropriate combination of a photoreactive semiconductor and an adsorbent, excellent harmful substance removal performance can be obtained. Many members having such a configuration have been devised. Under conditions of extremely high concentrations and high humidity, the adsorption of odors and harmful chemicals, which are usually present at low concentrations, to photoreactive semiconductors and adsorbents is impeded by water vapor, resulting in insufficient harmful substance removal performance. There were challenges.

Sufficient harmful substance removal performance can be exhibited.

行し易くなることなどが考えられる。It was further surprisingly found that the combined use of the dehumidifying filter has an unexpected effect of improving the life of the harmful substance removing performance of the composite filter member of the present invention. The mechanism by which this effect has occurred is not clear,
When the dehumidifying filter is not combined, the deodorizing filter expands and contracts by being continuously exposed to various conditions from low humidity conditions to high humidity conditions. In the composite state of the deodorizing filter and the adsorbent, a slight change such as loosening of the contact point between the photoreactive semiconductor and the adsorbent may occur, and the adsorption / decomposition performance of the deodorizing filter may easily deteriorate with time.

Can be used alone or in combination as appropriate. Further, after the sheet-like deodorizing filter and the dehumidifying filter are integrated by lamination or lamination, a pleated structure or a corrugated structure may be used.

By using the pleated structure, the area of the filter medium can be increased with respect to a certain ventilation area, so that the deodorizing performance and the dehumidifying performance can be improved. In addition, there is an advantage that pressure loss is reduced and air permeability is improved.

It can be made of a filter medium (here, a sheet-like deodorizing filter or dehumidifying filter) in accordance with JIS Z 1516-1995 “Corrugated cardboard for exterior”. The corrugated structure is not only extremely breathable due to its perforated structure, but also improves the deodorizing performance and dehumidifying performance because the area of the filter medium can be increased for a constant ventilation area like the pleated structure described above. Can be achieved.

どが考えられる。Although the mechanism of the expression is not clear, it was also found that the combined use of a dehumidifying filter has an unexpected effect that the life of the harmful substance removing performance of the composite filter member of the present invention is improved. Possibly, if the dehumidification filter is not combined, the deodorization filter expands and contracts due to continuous exposure under various conditions from low humidity conditions to high humidity conditions, and due to this expansion and contraction, it adsorbs to the photoreactive semiconductor In the composite state with the agent, it is conceivable that subtle changes such as loosening of the contact point between the photoreactive semiconductor and the adsorbent occur, and that the adsorption / decomposition performance of the deodorizing filter easily deteriorates with time.
