Frequently Asked Questions.

What Is Ozone?

Ozone, (O3), sometimes called "activated oxygen", contains three atoms of oxygen rather than the two atoms we normally breathe. Ozone is the second most powerful sterilant in the world and can be used to destroy bacteria, viruses and odors. Interestingly ozone occurs quite readily in nature, most often as a result of lightning strikes that occur during thunderstorms. In fact the "fresh, clean, spring rain" smell that we notice after a storm most often results from nature’s creation of ozone. However, we are probably most familiar with ozone from reading about the "ozone layer" that circles the planet above the earth’s atmosphere. Here ozone is created by the sun's ultra-violet rays. This serves to protect us from the ultra-violet radiation.

How Does Ozone Work?

The third oxygen atom of ozone makes it extremely reactive. This atom readily attaches itself to other odor molecules. When contaminants such as odors, bacteria or viruses make contact with ozone, their chemical structure is changed to less odorous compounds. As more ozone attacks the remaining compounds, the odor is eventually destroyed. This process is called oxidation. Ozone essentially reverts back to oxygen after it is used. This makes it a very environmentally friendly oxidant.

How Is Ozone Produced?

There are basically two methods of producing ozone...ultra-violet and corona discharge. Corona discharge creates ozone by applying high voltage to a metallic grid sandwiched between two dielectrics. The high voltage passes through the dielectric to a grounded screen/plate and in the process, creates ozone from oxygen present in the chamber. Ultra-violet (UV) light creates ozone when a wavelength at 254 nm (nanometers) hits an oxygen atom. Both processes split oxygen molecules into single oxygen atoms (O). These atoms combine with another oxygen molecule (O2) to form ozone (O3).

How Long Does The Ozone Last?

As soon as ozone is formed in the generator and dispersed in a room, it will start to revert back to oxygen. This step occurs by several processes including the following: Oxidation reactions with an organic material such as odors or smoke. Reactions with bacteria etc., which again consumes ozone by oxidation reactions. Additionally ozone breaks down thermally. Higher temperatures destroy ozone quicker than lower temperatures. The ozone that remains is referred to as Residual ozone.

"Residual" ozone created will return to oxygen usually within 30 minutes, in amounts equal to half its level. What this means is that after each subsequent 30 minute period there would be half as much residual ozone left at the end of the period as was present at the beginning of the period. This is similar to a geometric progression of 16;8;4;2;1. In practice the half life is usually less than 30 minutes due to temperature, dust, and other contaminants in the air. Therefore, ozone, while very powerful, doesn't last long. It does its job and then disappears back into safe oxygen.

Will The Odor Come Back?

No. If ozone is applied properly it destroys the source of the odor. Treatment times may vary depending on the strength of the odor but 98% of ozone treatments are successful. In the case of mildew the odor will return if you are unable to get rid of the moisture that is the source of the mildew.

What Is The Right Level Of Ozone?

The right level is when all the generated ozone is being consumed. This only applies to continuous ozone use in occupied environments – not for shock treating. However, this is difficult to attain because it becomes a balancing act. Initially the machine's output is set high to get rid of the problem odor as quickly as possible. As this is being accomplished less ozone is required for the diminishing odor etc., thereby leaving some residual ozone in the air. If the machine output is not turned down, then more residual ozone will remain. If a strong smell of ozone is noticed, then there is more ozone present than is required. Simply decrease the rheostat (output level control). With ozone, MORE IS NOT CONSIDERED BETTER! One must be careful when using ozone in a occupied environment.

NOTE: It is not necessary that ozone be detected by humans for it to be effective. Ozone can work even when humans are not able to smell it.

Is Ozone Harmful And What If Any Are The Long Term Effects?

Ozone has been known for almost a century, so a great deal is known about it. Several regulatory agencies, including the Occupational Safety and Health Administration (OSHA), have stipulated that the safe allowable level of residual is 0.10-ppm (parts per million). Note that this permissible level is for continuous exposure throughout an entire 8 hour day. The temporary affects of such a low exposure would range from headaches, to sore throats, irritation in the eyes, and nose. No long term effects have ever been documented from ozone exposure. Ask Ozone Solutions for MSDS sheets if desired.

Ozone Applications

Indoor air pollution is recognized as one of the major health concerns facing the nation today.

This condition has been created by the search for more energy efficient homes, buildings, and work places. Ozone generators can dramatically improve indoor air quality, creating a much safer atmosphere indoors.

Ozone is also great for mold and odor removal, as well as providing relief to people with dog, cat, and other pet allergies.

Ozone is ideal for removing smell in automobiles, limousines, buses, airplanes, recreational vehicles, rental cars, vans, boats, homes, basements, rest rooms, locker rooms, fitness facilities restaurants, kitchens, food services, walk-in coolers, grocery stores, butcher shops, office buildings, warehouses, motels, hotels, resorts, designated smoking areas, trash compactors, dumpsters, and more!

Pet area odors especially those from cat urine are very difficult to control. In residential homes, veterinary offices and kennels, ozone generators can treat odor-holding surfaces so well that it makes the presence of animals hardly noticeable. The use of high ozone "shock treatments" while the pets are out of the room helps remove stubborn pet odors and signifiantly improve air quality. Disinfecting pet areas of molds and bacteria is beneficial for pets and their owners alike.

When people are sick and confined to their bedrooms for extended periods of time, germs and bacteria build up in the room. A good shock treatment with Ozone while the room is unoccupied can be very beneficial in destroying these harmful contaminants, and even urine odor, if present.

, ozone generators are used by carpet cleaners, car washes, auto detailing, car dealers, apartment managers, fire departments, and professional cleaning services for smoke and flood restoration. Dry cleaners are using ozone generators to deodorize smoke damaged apparel and hocky equipment cleaning.

Ozone is great for recreating a smoke free room in hotels, motels or guest rooms. The ozone generators are great choices to get rid of the odors from beer, perfume, vomit, and the other odors left behind.

They also destroys odors from hair sprays, nail polish, and chemicals used for hair coloring and perms in hair salons.

Ozone gives added life to fresh fruit and vegetables reduces early losses in meat, poultry and fish. Florists use ozone generators in their coolers to extend flower life. Ozone is used in cold cellars to extend potato life.

The Food and Drug Administration has just amended its food additive regulations to permit ozone use as an anti microbial agent. The amendment, published in the Federal Register on June 28, 2001 allows for ozone use in gaseous and aqueous uses, and for safe and effective anti microbial treatment of meat, poultry, and other food products.

The ozone generator is used on the farm to reduce livestock odors, combat airborne and surface pathogens, and infection causing bacteria, viruses and spores in breeding areas, particularly in the poultry and swine industries
