Abstract: A water-filtration device filtrates water, has a main-filtration path and a bypassing-filtration path, and comprises a filter head, a water filter, a guiding assembly and an adjusting valve movably mounted at the filter head. The guiding assembly is mounted at the filter head and connected to the water filter. An O-ring of the adjusting valve can block an end of a bypassing portion of the guiding assembly. In the main-filtration path, water entering from a water inlet of the filter head does not pass through the bypassing portion, thereby completely passing through filter materials in a first filtrating room and a second filtrating room of the water filter. Water in the bypassing-filtration path passes through the bypassing portion and the filter material in the first filtrating room. The O-ring does not reach into the bypassing portion, thereby reducing wear and damage to the O-ring, and avoiding water leakage.
