Performance Data for Under-Sink Filtration System

  • Under Sink, Plumbed-In

  • 2000 Gallons (7500 L)

Testing of this filter system was performed by QFT, a lab now operating as IAPMO New Jersey, a division of IAPMO, an independent ISO 17025 certified laboratory that is capable of testing following NSF/ANSI protocols. All testing occurred under controlled laboratory conditions. Sample contaminants were prepared, measured and run through the filter. The filter results presented are the maximum removal percentage. Not all contaminants that were tested had established NSF/ANSI protocols at the time testing was performed. Actual performance may vary based on local water conditions. Not all contaminants may be present in users drinking water. System is designed for use with municipally treated tap water. Filter is not designed for use with water that is microbiologically unsafe or of unknown quality. Individuals with unknown water quality should follow the advice of local health authorities with regards to water treatment.

  • Chemical Disinfectants
    Chevron Down

    Chemical disinfectants are used to reduce the risk of water-borne diseases. The disinfection process can form disinfection by-products (DBP) that have been linked to cancer, reproductive issues, and damage to the liver, kidneys, and central nervous systems.

  • Fluoride
    Chevron Down

    Fluoride is a chemical compound added to 75% of tap water supplies in the U.S. on the pretext of promoting dental health. However, fluoride has been shown to do more damage to general health compared to its proclaimed benefits for dental health. In fact, water fluoridation may actually have no impact on dental health at all.

    Semi-volatile organic compounds (SVOC) are a subgroup of volatile organic compounds (VOC). Unlike most VOCs, SVOCs are odorless and harder to detect. Some examples of products that include SVOCs are many pesticides, oil-based products, and fire retardants. Most SVOCs can lead to cancer, reproductive disorders, nervous system damage, and immune system disruption.

  • Volatile Organic Compounds (VOCs)
    Chevron Down

    Volatile organic compounds (VOC) are organic chemicals released by a broad range of industrial, agricultural, and household products, including paint thinners, solvents, fertilizers, and gasoline that are quick to convert to a gas or vapor form. Long-term exposure to VOCs may lead to cancer or damage to the liver, kidney and central nervous system.
