Abstract
Abstract A shower water filter assembly which includes an elongated housing containing a cartridge of filter media, and which is connected to the water outlet in a shower. In order to permit the elongated housing to have sufficient length to efficiently perform a filtering function, a flexible hose is coupled to the bottom of the housing and extends through a tubular wand to the shower head. The wand and shower head are supported, for example, on the side of the cylindrical housing so as to provide sufficient elevation for the shower head for normal shower use. Alternatively, the wand and shower head may be removed from the supporting bracket and used manually for the shower.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
136 words
A shower filter assembly including: a housing having an elongated cylindrical configuration; a cylindrical cartridge containing filter media removably mounted in said housing in coaxial relationship therewith; a coupling member mounted at one end of the housing for attaching the housing to a water outlet; a flexible hose member having a first end connected to the other end of said housing for receiving filtered water from said housing; a tubular elongated wand connected to the other end of said flexible hose member; a shower head connected to the distal end of said wand; and bracket means mounted on the housing for removably supporting said tubular elongated wand and said shower head during the operation of the filter assembly with said wand extending upwardly from the lower end of the housing and inclined outwardly from the housing.
Claim 2
Dependent Claim
136 words
A shower filter assembly including: a housing having an elongated cylindrical configuration; a cylindrical cartridge containing filter media removably mounted in said housing in coaxial relationship therewith; a coupling member mounted at one end of the housing for attaching the housing to a water outlet; a flexible hose member having a first end connected to the other end of said housing for receiving filtered water from said housing; a tubular elongated wand connected to the other end of said flexible hose member; a shower head connected to the distal end of said wand; and bracket means mounted on the housing for removably supporting said tubular elongated wand and said shower head during the operation of the filter assembly with said wand extending upwardly from the lower end of the housing and inclined outwardly from the housing.
Claim 3
Dependent Claim
43 words
The shower filter assembly defined in claim 1, in which said bracket means is secured to one side of said housing, and which includes an arm mounted on said wand for removably supporting said wand and said shower head on said bracket means.
Claim 4
Dependent Claim
15 words
The shower filter assembly defined in claim 2, in which said arm is angularly adjustable.
Claim 5
Dependent Claim
