    Lead Water Filter Cartridge

    Water travels through a 1/2 micron Lead & Cyst removal Carbon Block Filter. Capacity: 6,000 gallons, depending on the detected level & ppb of influent water.

    SMART Water Filter Cartridge

    Water flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc (ERA-6500, ERA-9500). ERA-6500 and ERA-9500 are major advancements in water treatment technology that works on the electrochemical and spontaneous-oxidation-reduction (Eagle Redox Alloy®) principles. Chlorine is instantaneously and almost inexhaustibly oxidized.

    Water flows through ion exchange resins, reducing heavy metals such as lead, copper, aluminum, and water hardness.

    Water flows through granulated activated carbon (GAC). GAC is universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants, such as chlorine, chemicals linked to cancer (THM's, benzene) pesticides, herbicides, insecticides, volatile organic compounds (VOC's), PCB's, MTBE's and hundreds of other chemical contaminants that may be present in water causing bad taste and odors in your drinking water.

    All Crystal Quest® GAC is a mixed blend of coconut shell and catalytic GAC to address both chlorine, chloramines and these byproducts. 

    Carbon Block Water Filter Cartridge

    Water travels through a 5-micron solid carbon cartridge for removing volatile organic carbon compounds (VOC's), insecticides, pesticides and industrial solvents and traps particles larger than 5 microns including sediment, silt, sand, and dirt.
