A connector for a water purification filter is provided to lower costs, and to prevent leakage of residual water remained in the connector body when separating the water purification filter from a connector body by reducing the number of components including a flow path conversion valve and a plunger and simplifying structure of the connector. A water purification filter connector with which a water purification filter is removably combined comprises: a connector body(4) in which a raw water inlet(1), an outlet(2), a purified water moving passage(8), and a raw water moving passage(5) are formed; a flow path conversion valve plunger(6) discharging raw water flown in through the raw water inlet to the outside through the raw water moving passage and outlet when separating the water purification filter from the connector body; a first elastic member(7) pressurizing the flow path conversion valve plunger; a check valve plunger(9) opening or closing the purified water moving passage according to attachment or detachment of the water purification filter relative to the connector body; a second elastic member(10) pressurizing the check valve plunger; a valve seat(12) closing an upper end of the raw water moving passage when the water purification filter is combined with the connector body and opening the upper end of the raw water moving passage when the water purification filter is separated from the connector body; and a lower projection(6b) supporting a second O-ring(14) and preventing coming-off of the flow path conversion valve plunger due to a cross-sectional area difference between the lower projection and an upper projection(6a) caused by raw water flown in the raw water moving passage.
