PURPOSE:To hold a wide deodorizing spectrum and to minimize the influence of humidity to adsorptivity by containing at least one type of a zeolite type aluminosilicate of a prescribed chemical composition and its hydrogen ion exchanger. CONSTITUTION:At least one type of the zeolite type aluminosilicate of chemical composition expressed by a general formula I on the basis of oxide and its ion exchanger. The zeolite type aluminosilicate and the hydrogen ion exchanger have the characteristic that the mole ratio of SiO2/AL2O3 is 20 or above and significantly larger than usual zeolite, for example, A type, X type and Y type ones. |
