PURPOSE:To obtain the title deodorizing filter wherein the deodorizing body can be easily handled by laminating respectively a fibrous member with deposited porous ceramic particles impregnated with a deodorant and a fibrous member with deposited activated carbon particles. CONSTITUTION:The first filter 2 is obtained, for example, by depositing porous ceramic particles 8 impregnated with a deodorant on the fiber 6 of an air- permeable member 5 of foamed urethane, unwoven fabric, etc. having three- dimensional fibrous structure with an adhesive 7. The second filter 3 is obtained by depositing activated carbon particles 9 on the fiber of an air-permeable member 5 having the same structure as the first filter. Since each particle 8 and 9 is deposited on the fiber 7, the air permeability of the air-permeable member is maintained. The first and the second filters 2 and 3 are bonded to each other with an adhesive, and encased freely detachable in a vessel 1 provided with many air holes 4. |
