Image Number 3 for United States Patent #5151179.
A faucet mounted water filtration unit having two tubular hollow legs depending from a base member with a coupler for attaching the unit to a faucet spout, with the spout straddled by the legs and the unit positioned about the faucet. One leg brings unfiltered water from the faucet spout attachment into the filter housing containing a replaceable cartridge. The other tubular leg brings filtered water from the filter unit to an outlet port. A diverter valve on the base allows one to bypass the filter unit to receive unfiltered water.
