Our three stage WaterSentinel® WS-UF3LCV system is designed to provide clean, clear, crisp drinking water for your whole family. Its compact under-counter design allows for simple installation where space is limited, while holding all the necessary power to deliver fresh, great-tasting water straight to you for your enjoyment.

Unlike other systems, the WS-UF3LCV requires no electricity or separate water holding tank, making it easy to install and use. The WS-UF3LCV includes three stages of ultra water filtration beginning with a high capacity 5 Micron Sediment Filter which removes sand, silt, sediment rust and other suspended particles. Stage two is a 0.02 micron UF Membrane, followed by our stage three LCV Carbon Block for the reduction of lead, Cryptosporidium, Toxoplasma, Giardia, Entamoeba, as well as a long list of Volatile Organic Chemicals including herbicides, insecticides, pesticides, disinfection by products and more (see performance data sheet for complete list of VOC's). This system also reduces chlorine taste and odor from your drinking water to ensure a crisp, clean product for you and the family.

The WaterSentinel® 3 Stage System includes our unique clear housing around the sediment filter which makes it a breeze to know when to replace the filter. The WaterSentinel® 3 Stage Ultra Filtration System includes all hardware necessary for standard installation, including the System Module, filter elements, a High-Quality Lead Free Chrome Faucet, Adapt-A-Valve and tubing for an all-in-one, ready to use system. Simple to install and maintain, the WaterSentinel® 3 Stage Ultra Filtration System will deliver fresh, great-tasting water for drinking and cooking to you and your family.
