Abstract
Disclosed is a filter assembly capable of adjusting elimination of solid materials using a flow-variable bypass flow path. The filter assembly includes a filter portion (100) which includes a cover portion (110) formed on top to have a shape in which a bypass flow pipe (112) and a water discharge pipe (113) sequentially surrounds a perimeter of a vertically protruding original water inflow pipe (111) in a stepped structure and accommodates a filter body therein and a filter cartridge header (200) in which the cover portion (110) of the filter portion (100) is accommodated therebelow and which includes a bypass flow rate control unit (300) capable of adjusting an inflow amount of original water flowing into the bypass flow pipe (112).
