PURPOSE:To provide a filter having different functions which is composed of a gas-moisture permeable sheet and has a honeycomb structure with plural cylindrical holes. CONSTITUTION:A filter has a sheet 4a in which active carbon is deposited, a sheet 4b which is impregnated with sodium hypochlorite, a sheet 4c in which ferrous sulfate is deposited, and a sheet 4d which has a two-layered structure in which the coarse side sucks fluid in flow (arrow) and the dense side discharges fluid. These sheets are set in a frame, with the face parallel to the three rows of cells (a face in the B direction) arranged as a filtration surface. |
