This water filter combines two filtration technologies to provide cleaner, healthier water for you and your family. Once the system is installed, water passes through a five-micron sediment filter that reduces sand, silt, sediment and rust from the drinking water. The water then passes through a heavy-duty, one-micron coconut shell carbon block filter that reduces lead, parasitic cysts, and chemicals. This specially-formulated filtration process is capable of reducing cryptosporidia, giardia, entamoeba, and toxoplasma, as well as a long list of chemicals--from herbicides and pesticides to disinfection byproducts and gas additives. It is estimated that VOCs (volatile organic chemicals) are present in one-fifth of the nation's water supplies. These contaminants can enter ground water from a variety of sources, including herbicide and pesticide runoff, gasoline or oil spills, leaking underground fuel tanks, disinfection byproducts, septic system cleaners, and chemicals used in the dry cleaning industry. This premier, two-stage water filtration system keeps you safe from these and other chemicals with its two-stage filtration, so you can turn on the tap with the assurance that you're getting cleaner, healthier drinking water.
