Abstract

A kit for purifying water comprises a first container for receiving untreated water, and a second container for receiving purified water and having a dispensing spigot. A water purification composition, when mixed with water in the first container, produces partially purified water having solid matter. A first filter held in a filter holder at an upper end of the second container removes the solid matter when the partially purified water is poured from the first container. A second filter in the second container comprises carbon.
