PROBLEM TO BE SOLVED: To provide a water cleaning cylinder packed with active carbon, in which cleaning performance is improved by uniformly filtering water. SOLUTION: The water cleaning cylinder 10 is provided with: an inflow port 1 for untreated water on one edge part; an outflow port 2 for treated water on the other edge part; and an active carbon layer 3 packed with active carbon at the inside, and the water cleaning cylinder 10 cleans water by causing water flowing from the inflow port 1 to pass through the active carbon layer 3, thereafter causing the water to flow out of the outflow port 2, wherein the space between the inflow port 1 and the active carbon layer 3 is provided with a separation chamber 4 packed with granular bodies 5 larger than the active carbon.
