The filtration device (1) switches between a water purification mode, a first backwashing mode, and a second backwashing mode in accordance with the pivot position of a valve element (6). During the first backwashing mode, a source water inlet (51) is in communication with a second source water through-port (53), and first and second purified water through-ports (54, 55) are blocked from communication with a purified water outlet (56), whereby purified water from a second filter (3) is backwashed through the first filter (2) and the drain water is discharged from a drain water outlet (57). During the second backwashing mode, the source water inlet (51) is in communication with a first source water through-port (52), and first and second purified water through-ports (53, 54) are blocked from communication with the purified water outlet (56), whereby purified was from the first filter (2) is backwashed through the second filter (3), and the drain water is discharged from the drain water outlet (57).</p>
