The replaceable gas cartridges  38  are made from PVC plastic and are equipped with easily connected and disconnected fittings. The disposable purifying chamber  20  contains a particulate filter and an activated charcoal filter to remove odors and microorganisms from the input water. The mixing chamber  18  is made from PVC plastic for long life and resistance to chemical action from concentrated materials used with the system.  
         [0036]    Soap, detergent, fragrance or disinfectant is stored in small stainless steel or PVC plastic canisters and a measured amount is introduced into the mixing chamber via small push button stainless steel or PVC plastic injection valves. The mixed solution is transferred from the mixing chamber via a length of flexible PVC tubing to a hand held PVC plastic nozzle fitted with a metering valve.  
         [0037]    The instant invention is used as follows. The personal hygiene device  10  is connected to a source of pressurized water using the saddle valve or quick connect fittings  36  and  34  or  35 . The input water is turned on to provide flow. The desired amount of concentrated additive is injected into the mixing chamber  18  using the push button valves. The push button valve  31  on the dispensing nozzle  29  is temporarily opened to allow flow of input water into the mixing chamber  18 . The mixed solution is dispensed in the quantity needed using the desired nozzle head  30 . The by-pass valve is actuated when purified water only is desired. After use the input valve is turned off, the dispensing control valve  31  actuated to remove excess pressure and the dispensing assembly stored in the cabinet for future use. Replacement canisters  46  of concentrated additive are exchanged as necessary.  
         [0038]    The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment.
