Water Travels Through 10 Stages of Filtration:

  • STAGE 1:  Water flows through a pre one-micron filter pads (1 micron equals 1/25,000th of an inch), which remove suspended particles such as silt, sediment, Giardia, Cryptosporidium, sand, rust, dirt, and other undissolved matter. 
  • STAGE 2:  Water passes 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 (99.9%), 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, bad taste, and odors from your drinking water.

  • STAGE 3:  Water flows through another one-micron filtration pad for further reduction of undesirable particles and a wide variety of contaminants.
  • STAGE 4:  Water passes through a Crystal Quest® Reverse Osmosis (RO) membrane, which removes and filters particles as small as 1/10,000 of a micron as most inorganic chemicals (such as salts, metals, minerals) most microorganisms including Cryptosporidium and Giardia, and most inorganic contaminants.

  • STAGE 5:  Water flows through another one-micron filter pads (1 micron equals 1/25,000th of an inch), which remove suspended particles such as silt, sediment, Giardia, Cryptosporidium, sand, rust, dirt, and other undissolved matter.
  • STAGE 6 & 7:  Water flows through 2 beds of Eagle Redox Alloy® (Oxidation/reduction process) media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc. Representing a new and unique way of water processing medium which by its natural process of electrochemical oxidation/reduction and adsorption action reduces and/or removes many unwanted contaminants from water. It is a major advancement in water treatment technology that works on the electro-chemical and spontaneous-oxidation-reduction (Eagle Redox Alloy®) principles. Chlorine is instantaneously and almost inexhaustibly oxidized. Iron and hydrogen sulfide are oxidized into insoluble matter and attach to the surface of the media. Heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals are removed from the water by the natural process of electrochemical process. They are attracted to the surface of the media, much like a magnet. The media inhibits bacterial growth throughout the entire unit. Read more about Redox (oxidation/reduction) process HERE
  • STAGE 8:  Water flows through the ion exchange resin, reducing heavy metals such as lead, copper, aluminum, and water hardness.
  • STAGE 9:  Water passes again through granulated activated carbon (GAC). 
  • STAGE 10:  Water flows through a post one-micron filtration pad for further reduction of undesirable particles. The end result is a great reduction or elimination of a wide variety of contaminants.

Excellent product

I have been using them from last 10 years. The water tastes like premium mineral water whether in Ohio or in South ( tap water is distasteful here). Customer service/sales agent was very professional and courteous and helped correcting a mistake I made during ordering. The price is totally worth it and a money saver on long run.
