The formation of oxygen into ozone O3 occurs with the use of energy. This process is carried out by an electric discharge field as in the CD-type ozone generators (corona discharge simulation of lightning).

Ozone is a naturally occurring component of fresh air. It can be produced by the ultraviolet rays of the sun reacting with the Earth’s upper atmosphere (which creates a protective ozone layer), by lightning or it can be created artificially with an ozone generator.

The ozone molecule contains three oxygen atoms whereas the normal oxygen molecule contains only two. Ozone is a very reactive and unstable gas with a short half-life before it reverts back to oxygen. Ozone is the most powerful and rapid acting oxidizer man can produce, and will oxidize all bacteria, mold and yeast spores, organic material and viruses given sufficient exposure.
In the home, ozone is often combined with activated carbon filtration to achieve a more complete water treatment.


  • Ozone is primarily a disinfectant that effectively kills all biological contaminants.
  • Ozone also oxidizes and precipitates iron, sulfur, and manganese so they can be filtered out of solution.
  • Ozone will oxidize and break down many organic chemicals including many that cause odor
    and taste problems.
  • Ozonation produces no taste or odor in the water. Since ozone is made of oxygen and reverts to pure oxygen, it vanishes without a trace once it has been used.


  • Ozonation requires electricity to operate. In an emergency situation when the power is out, it will not work
  • Ozone is not effective at removing dissolved minerals and salts.
