  • Patent number: 6325930
    Abstract: A showerhead having a water filter element held therein. The water filter element is easily changeable by unscrewing two halves of a body forming the showerhead. The body halves are easily gripped and turned, so as to be opened or closed, and the showerhead preferably includes a massage-type head at the lower end thereof, which may be rotated to vary the streams of water exiting the showerhead. The water filter element cooperates with internal components of the halves of the body to direct the flow of water through the filter element, and then out of the massage head. The showerhead may be easily and quickly adapted to be held on any shower arm, and to replace any existing showerhead without taking up as much room as currently existing filter elements used with available showerheads.

  • Patent number: 6187187
    Abstract: A shower filter assembly, having a thin or low-profile design, including a recessed inlet, which leads into an internal chamber having a filter element mounted therein to deflect water flowing into the internal chamber substantially evenly through a filter media held within the filter element. Magnets are provided in the compact shower filter to act on the water flowing therethrough, so as to breakdown carbonates therein and prevent the formation of line and scale deposits.

  • Patent number: 6016977
    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.

  • Patent number: 5503742
    Abstract: A shower filter assembly having an in-line reversible filter, changeable by unscrewing two portions of the housing. The housing exterior includes a plurality of gripping means to allow easy opening and closing of the housing and to prevent slippage of the hands of a user gripping the two portions, even when wet. The shower filter assembly includes a separate internal filter element that may be easily inserted into or removed from the shower filter assembly to allow the internal filter element to be easily reversed for longer use.
