Abstract

A filter for a water-purification device includes a filter housing having a water inlet and a water outlet defined therein, and a filter member disposed in the filter housing to purify water introduced through the inlet and supply the purified water to the outlet. The filter member includes a carbon block produced by mixing 40 to 50% by weight of titanium oxide, 30 to 40% by weight of activated carbon, and 18 to 23% by weight of binder with each other.
