Water Travels Through Multiple Stages of Filtration

SMART Cartridge

  • Water passes through coconut shell granulated activated carbon (Arsenic-Free GAC™). GAC is universally recognized and regularly used as an effective adsorbent for removing or reducing a wide variety of organic contaminants, bad taste, and odors from drinking water.
  • Water flows through the ion exchange resin, reducing heavy metals such as lead, copper, aluminum, and water hardness.
  • Water flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc (Eagle Redox Alloy® 6500 and Eagle Redox Alloy® 9500.)
  • Water flows through Ceramic and Tourmaline balls to enhance the water and maintain a more alkaline pH. 

Sediment Cartridge

  • Water flows through a premium sediment cartridge that removes sediment, silt, sand, and dirt.

Carbon Block Cartridge

  • Water flows through a premium, solid carbon filter cartridge for removing or reducing volatile organic compounds (VOCs), insecticides, pesticides, industrial solvents, and more.
