Abstract
A hand held shower head and filter assembly for attachment to a waterline to remove chlorine and other substances from water. This assembly includes a reversible and reusable filter assembly for use with hot water passing through a two stage bed of ceramic-type calcium sulfite beads and a copper/zinc material. The device includes an elongated, hollow handle which holds the filter element therein in such a manner that the filter media reacts with or removes chlorine and other substances more efficiently from shower water, thereby allowing a greater volume of water to be treated, as well as the treatment of water at elevated temperatures, in a more versatile and useful device.
