초록

Water purification is performed in a simplified manner within a vessel having at least the lower porton thereof filled with a filtration media such as activated carbon. A spout is provided near the upper end. A filter media placed in the spout. The top of the vessel is closed with a cap which is vented to permit the escape of matter which is vaporized during the heating phase. The vessel preferably has a handle to aid in the dispensing of the purified water. The vessel is preferably formed of a material which is safe for use in microwave heating devices....
