Stage #1 - Five Micron Sediment Filter (WP105311) traps sediment and other particulate matter like dirt, silt, and rust which affect the taste and appearance of your water. Note - Recommend changing every 6 months

Stage #2 - LVOC (Lead and Volatile Organic Compound) Carbon Block Filter (WP105371) reduces lead as well as harmful Volatile Organic Chemicals (see performance data sheet for complete list of VOC’s). It is estimated that VOC’s are present in ⅕ of the nation’s water supplies. These water contaminants can enter ground water from a variety of sources including localized use of herbicides and pesticides, gasoline or oil spills, leaking underground fuel tanks, septic system cleaners, and chemicals used in the dry-cleaning industry. Note - Recommend changing every 12 months.

Stage #3 - UF Membrane (UF Hollow Fiber Technology Membrane). (WP105321) Ultra filtration is a membrane filtration process which uses standard home water pressure to push water through its semi permeable membrane. Suspended particles and materials of high molecular weight are unable to pass through the 0.1 Micron (Nominal) UF membrane, allowing only fresher cleaner water and dissolved minerals to pass through. Historically this separation process has been used in large municipal water treatment plants and hospitals; however through advances in technology it is now available to you as a powerful under sink water filtration plant in your home. Note - Recommend changing every 12 months.

Annual Filter Kit - WP560039 This kit contains two Sediment Filters (WP105311), two LVOC Carbon Block Filters (WP105371), and one UF Membrane.
