US4-S Hi-flow Undersink Purifier with Sediment Filter & T-Style Faucet

H2O under counter water purifiers are neatly installed under the kitchen counter and attached to the cold water supply. Each Premier unit comes with a separate, chrome faucet that is fitted on top of the counter, next to your sink or prep-bowl.

The US4-S is a high capacity/high flow under counter water purifier that utilizes a 1 Micron Polypropylene pre-sediment filter and a special, replaceable US4 GAC/KDF/Riolyte water purifier cartridge. The US4-S is the top of the range that offers high capacity and high flow rate, and can therefore be connected directly to your existing tap or mixer. This purifier is suitable for large families, or light commercial applications.
