A method for controlling the purified water passage of a refrigerator with a water purifying filter is disclosed. The refrigerator has a first valve for controlling water supply to the water purifying filter and a second valve for controlling water supply to a dispenser and an ice-making unit. The method comprises the following steps. A first step is determining whether the dispenser and the ice-making unit are operated. A second step is opening the first and second valves if the dispenser and the ice-making unit are operated. A third step is determining whether a refrigerator compartment door and a freezer compartment door are closed if one of the dispenser and the ice-making unit is operated. A fourth step is closing the first and second valves if at least one of the refrigerator compartment door and the freezer compartment door is opened. A fifth step is closing the first and second valves if the dispenser and the ice-making unit are not operated.
