Water travels through 9 stages of filtration:
In stage 1, water passes through a granulated activated carbon (GAC) cartridge. 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 (VOCs), PCB's, MTBE's and hundreds of other chemical contaminants that may be present in water, which cause bad tastes and odors.

In stage 2,Water passes through a reverse osmosis membrane, which removes substantial amounts of most inorganic chemicals (such as salts, metals, minerals) most microorganisms including cryptosporidium and giardia, and most inorganic contaminant.

In stage 3, Water travels through an Ultrafiltration (UF) membrane. Ultrafiltration (UF) is an important purification technology used for the production of high-purity water. UF is effective for the removal of colloids, proteins, bacteria, viruses, parasites protozoa and pyrogens, (e.g., gram-negative bacterial endotoxins), and other organic molecules larger than 0.2 Micron size and most other water contaminations known today. Also removes pesticides and herbicides, as well as the hardness in water and salts.

In stage 4, water flows through one-micron filter pads (1 micron equals 1/25,000th of an inch), which remove suspended particles such as silt, sediment, cysts (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.
In stages 5 and 6, water flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc (KDF). KDF is a major advancement in water treatment technology that works on the electro-chemical and spontaneous-oxidation-reduction (KDF) principles. Chlorine is instantaneously and almost inexhaustibly oxidized.

In stage 7, water flows through ceramic balls, which remove harmful bacteria such as E. Coli, Fecal coli form, Salmonella, Streptococcus, cysts (Cryptosporidium, Giardia), and sediment.
In stage 8, water travels through another bed of granulated activated carbon (GAC).
In stage 9, water flows through another one-micron filtration pad for further reduction of undesirable particles. The end result is a great reduction or the total elimination of a wide variety of contaminants.
