About the Filtration Process
For drinking water to become crystal clear, a polishing filter is used before the water is channeled past the Ultraviolet Light disinfecting process. First Water uses a 0.5-micron, Carbon Block Filtration Process as its polishing filter on all of its water purification systems. Because chemicals are adsorbed by the carbon, the filter needs to be changed every 6 months. This filter has the capabilities of reducing Giardia and Cryptosporidium Cysts, Herbicides, Pesticides, Trihalomethanes (THMs), certain Volatile Organic Chemicals (VOCs), Chlorine and Chlorine By-Products, Sediment, Bad Taste, Odors, Color, Smell, and many other Harmful Chemicals and Contaminants down to a 0.5 micron.
About the Ultraviolet Light Disinfecting Process
First Water's Ultraviolet Light disinfecting process makes the crystal clear water to be channeled around the UV light rays in a unique double-pass method. The Ultraviolet light rays pass through clear water much easier then through cloudy, sediment laden, dirty (turbid) water. When harmful microbes are exposed to the UV rays, their nucleic acid absorbs the light rays, which then scrambles the DNA structure and prohibits reproduction of the cell therefore rendering the cell sterile and no longer able to reproduce. The cell is now consider dead and is no longer a threat to water consumption. The UV bulb in all systems needs to be replaced every 12 months with normal usage. The UV process the ability to kill the Bacteria, Viruses, Typhoid Fever, Coliform, Dysentery, Cholera, Infectious Jaundice, Hepatitis and Influenza Virus, E-coli, Enteric Fever and many other unwanted microorganisms to a 99.999% purity.

COMMON USES
- purifies any contaminated fresh water (does not remove salt from salt water)
- in developing areas, utilize wells, ponds, lakes, streams, rivers, swamps, etc.
- very easy operations eliminate the need for persons with technical skills
- incredible portability and flexibility for any emergency management need
- in urban areas, utilize compromised water pipes, flooded streets, swimming pools, etc.
- in rural areas, utilize fire tankers, natural water sources, operations runoff, etc.
