PURPOSE:To obtain a filter with high deodorizing efficiency by forming lots of punched pores in block-like objects formed by stacking corrugated fiberboards and making microbes and enzymes which have deodorizing functions adhere to them. CONSTITUTION:A filter 1 is comprised of lots of corrugating medium paperboards 3 and liner paperboards 4 of corrugate fiberboards 2 laminated so as to arrange all small through holes 2a in lines in one direction. Lots of punched pores 5 are made in the corrugating medium paperboards 3 and liner paperboards 4 of corrugated fiberboards 2 in which small through holes 2a are formed. A solution containing microbes or enzymes having deodorizing function is adhered to or impregnated in this filter 1 made of the corrugated fiberboards. The filter 1 is placed in an unpleasant air passage while the small through holes 2 are set in the direction of the air flow and an unpleasant odor air is introduced. The filter may be formed by laminating the corrugated fiberboards in a voluted shape. |
