Abstract
A composite filter and a water purifier including the same, in which the discharging of washing water and the input of raw water and the output of purified water are possible, and filter members are integrated to form a composite filter. A head member of a housing part is provided with first and second partition walls to form independent flow paths in which the raw water, the purified water and the washing water do not mix. Passages through which the raw water, the purified water and the washing water flow are concentrated on the upper side of the composite filter. A second filter member is disposed in a filtering unit so as to surround a first filter member by first, second and third upper cap members, and thus, the composite filter can be manufactured by utilizing a pre-manufactured first filter member such that manufacturability is enhanced.
