Alkalizing Water Filter Cartridge

Water travels through an Alkalizing cartridge with our Ionizer media, containing magnesium & calcium to increase oxygenation & drive the pH higher.

SMART Water Filter Cartridge

Our special house blend of 2 types of coconut-shell GAC (including Catalytic) with 2 types of Eagle Redox Alloys® (9500 & 6500) & anion exchange resin. This blend effectively reduces & removes heavy metals, chlorine & chloramine, pesticides & herbicides, pharmaceutical by-products & other inorganic substances such as petroleum byproducts. Ceramic and Tourmaline balls to enhance the water and maintain a more alkaline pH. To read about how GAC's work, click here. To read about the ERA® Oxidation/Reduction Process, click here.

Water flows through our SMART special house blend of 2 types of coconut-shell GAC (including Catalytic) with 2 types of Eagle Redox Alloys® (9500 & 6500) & anion exchange resin.

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 or reducing volatile organic carbon compounds (VOC's), insecticides, pesticides and industrial solvents and traps particles larger than 5 microns including sediment, silt, sand, and dirt.
