1. A complex filter for water purification, comprising: a housing; an inlet formed at an upper side of the housing, wherein water to be purified is introduced through the inlet; an outlet formed at a lower side of the housing, wherein the water to be purified is purified and then discharged through the outlet; a first activated carbon layer and a second activated carbon layer located between the inlet and the outlet, wherein the first activated carbon layer is a distance apart from the second activated carbon layer; first second and third activated carbon fiber layers configured to prevent granular activated carbons of the first activated carbon layer and the second activated carbon layer from being mixed with other layers, wherein the first activated carbon fiber layer is disposed at an upper side of the first activated carbon layer, the second activated carbon fiber layer is disposed between the first activated carbon layer and the second activated carbon layer, and the third activated carbon fiber layer is disposed below the second activated carbon layer; and a hollow fiber membrane-disposed between the third activated carbon fiber layer and the outlet.
