Abstract: A filter for a water purifier includes a filter housing that defines an inlet and an outlet, and a filter module disposed inside the filter housing and configured to purify water received through the inlet and supply purified water to the outlet. The filter module includes a carbon block that includes a mixture of: activated carbon having a weight corresponding to 40 to 50% of a weight of the mixture, a binder having a weight corresponding to 5 to 15% of the weight of the mixture, iron hydroxide having a weight corresponding to 10 to 20% of the weight of the mixture, and titanium oxide having a weight corresponding to 30 to 40% of the weight of the mixture.

Abstract: A method is described for treating activated carbon configured to be included in a carbon block of a filter for a water purifier. The method includes: inserting the activated carbon into a chamber; injecting ozone generated from an ozone generator into the chamber, and applying pressure to the chamber; and modifying a surface of the activated carbon inserted into the chamber based on applying the pressure to the chamber that holds the ozone and the activated carbon.

Abstract: Disclosed is a filter for a water-purification device, the filter including 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, wherein 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. Further, a water-purification device including the filter is disclosed.
