Single-use long-life faucet mounted water
filtration devices are disclosed. A bathroom water
filtration device having two outlets for filtered water is disclosed. A rotatable fountain head adjustable in three axes is included for use in the bathroom water
filtration device. Press control of the water expelled from the fountain head is controlled by a valve arrangement which divides the flow between the two filtered water outlets. The water filtration device is of unibody construction formed by ultrasonically
welding certain parts thereof together. The filter housing end cap includes stops to insure that the filter
assembly does not rotate. Since the devices disclosed are disposable, no filter replacement or other maintenance is performed. A gate,
magnet(s), sensor and
electronics provide an indication of filter performance enabling disposal of the water filtration device and installation of a
new device. A kitchen water filtration device is larger than the bathroom device. Both the kitchen and bathroom water filtration devices are small and are mounted behind the faucet connection so as to facilitate full utilization of the sink or wash basin
