  • Heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, other dissolved metals and water hardness
  • Organic contaminants, such as 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

3Post tank UF cartridge

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. This cartridge is placed between the holding tank and the faucet. 

4UV Sterilizer

The UV Sterilizer kills bacteria including coliform and E.coli, as well as viruses, yeasts, mold spores, and oocysts such as cryptosporidium or giardia that may have escaped through the RO membrane. The UV Water Sterilizer system is the most economical way of treating water (99.99% reduction in bacteria and viruses). Furthermore, this process is accomplished without adding any potentially harmful chemicals to your drinking water.
