Watts Volatile Organic Chemicals (VOC) Carbon Block Filter Cartridges 7100450

Volatile Organic Chemicals (VOC) Carbon Block Filter Cartridges are capable of reducing harmful VOC's such as MTBE's, lindane, atrazine, benzene, 2, 4-D, and others from your drinking water (See performance data sheet for a complete list of VOCs). It is estimated that VOC's are present in one-fifth 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. The faucet has a self-contained timer that uses a flashing light to indicate when it's time to change filters.
