A composite filter-cartridge (100), a composite filter-cartridge assembly for a water purifier and a water purifier are provided. The composite filter-cartridge (100) includes a pretreatment filter-cartridge (110), a fine filtration filter-cartridge (120) and an activated carbon filter-cartridge (130) arranged sequentially from outside to inside. The fine filtration filter-cartridge (120) includes a first water collecting pipe (121) and a fine filtration membrane (122). The activated carbon filter-cartridge (130) includes: a second water collecting pipe (131), an outer circumferential wall of the second water collecting pipe (131) except a lower end thereof and an inner circumferential wall of the first water collecting pipe (121) being spaced apart from each other; and a activated carbon (132), lower ends of the activated carbon (132) and the second water collecting pipe (131) being in sealed connection, a water outlet hole (132a) being formed in the activated carbon (132) and penetrating the activated carbon (132) axially, and an upper end of the water outlet hole (132a) being closed.
