|Ozone machines for cleaning indoor air|
Ozone machines create O3 which is also known as activated oxygen or trivalent oxygen. Ozone is a natural component of the air we breathe each and every day.
In nature, ozone is generated when oxygen (O2) molecules are split into two separate atoms by ultraviolet radiation from the sun, lightning and electric arcs. The freed atoms recombine in three-atom groups to form cousins of oxygen - or ozone (O3). Ozone machines typically use electric arcs or ultra violet light to create ozone.
Ozone, one of the most powerful oxidizing agents occurring naturally in our clean outdoor environment, has the capacity to break down many of the organic chemicals that foul our indoor environment. Highly reactive ozone combines with pollutants and neutralizes them by breaking them down into water, carbon dioxide, nitrogen, sulfur and oxygen.
Ozone is, however, missing from our indoor environment. Ozone, because of its reactivity, must be continually renewed. Ozone concentrations reduce quickly ¡ª with ozone initially at a concentration of .03 parts-per-million (ppm) outside, totally reverting to oxygen in a period of 20 to 50 minutes ¡ª depending on a variety of conditions. Unless efforts are made to continuously restore this level in a modern building, the ozone level will normally be zero.
Ozone (activated oxygen) doesn't merely mask odors and harmful substances, it seeks out and eliminates them at their molecular source.
Ozone machines create the ozone necessary to react with the sources of unpleasant or hazardous indoor odors and chemicals. Chemical pollutants (cigarette smoke as an example, with its 3,600 plus chemicals) are broken down into their basic molecular components, thereby neutralizing them. Having given up its unpaired third oxygen atom in the process, the ozone molecule itself becomes plain oxygen again.
For example: formaldehyde - found in plywood, cabinets, furniture, tobacco smoke, office dividers, new carpets, new drapes, wallpaper, paneling and particle board.
Formaldehyde + Ozone ==> Carbon Dioxide + Water + Oxygen
HCHO + 2O3 ==> CO2 + H2O + 2O2
Bacteria, viruses, molds and fungi (mildew), which can cause unpleasant odors, allergic reactions and sometimes disease, are killed when they react with ozone. As with chemical pollutants, the outer membranes or shells of these microorganisms contain receptors that can absorb ozone, which proceeds to break them down. Without its protective membrane or shell, the bacterium, mold or fungus dies.
For people who suffer from allergies and environmental sensitivities, or those who just want to freshen up musty, smelly basements, "ground level" ozone can be a powerful ally.
Average outdoor ozone levels in unpolluted areas are between .03 and .05 parts-per-million. The highest naturally-occurring levels are found at seashore, forest and mountain locales - places people go to vacation and feel refreshed. The fresh, invigorating air after a spring electrical thunderstorm is ozone. So is the smell of air-dried laundry on a clothes line.
The Food and Drug Administration (FDA) declares .05 ppm as the safe level for 24-hour-a-day inhalation. This is a conservative standard, since natural levels of ozone often reach .065 ppm -- 25 percent higher than the FDA's "safety" limit.

Ionization Test Results
Our whole home air purifiers are designed to produce .02 to .04 ppm of ozone when set for 24 hour a day use. The air purifier can also be set at higher levels to sanitize an unoccupied area quickly. The ionic air purifiers copy the same methods Mother Nature is using to keep the air clean outdoors.
Ozone machines producing low levels of ozone, for use as air and water purification, have many benefits to offer.
