Manufacturers and vendors of ozone devices often use misleading terms to describe ozone and its effectiveness in odor removal inside a home or auto.
Terms such as “energized oxygen” or “pure air” suggest that ozone is a healthy kind of oxygen.
Ozone is a toxic gas with vastly different chemical and toxicological properties from oxygen. Several federal agencies have established health standards or recommendations to limit human exposure to ozone
Even at high concentrations, ozone may have no effect on biological contaminants embedded in porous material such as duct lining or ceiling tiles (Foarde et al, 1997). In other words, ozone produced by ozone generators may inhibit the growth of some biological agents while it is present, but it is unlikely to fully decontaminate the air unless concentrations are high enough to be a health concern if people are present. Even with high levels of ozone, contaminants embedded in porous material may not be affected at all.Conclusions
Whether in its pure form or mixed with other chemicals, ozone can be harmful to health.
When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and, throat irritation. It may also worsen chronic respiratory diseases such as asthma as well as compromise the ability of the body to fight respiratory infections.
Some studies show that ozone concentrations produced by ozone generators can exceed health standards even when one follows manufacturer’s instructions.
Many factors affect ozone concentrations including the amount of ozone produced by the machine(s), the size of the indoor space, the amount of material in the room with which ozone reacts, the outdoor ozone concentration, and the amount of ventilation. These factors make it difficult to control the ozone concentration in all circumstances.
Available scientific evidence shows that, at concentrations that do not exceed public health standards, ozone is generally ineffective in controlling indoor air pollution.
The concentration of ozone would have to greatly exceed health standards to be effective in removing most indoor air contaminants. In the process of reacting with chemicals indoors, ozone can produce other chemicals that themselves can be irritating, corrosive and leave an unwanted and lingering odor of its own.
There is no “safe” level of ozone. For many people, even at the 50 parts per billion of ozone allowed by the EPA, exposure far exceeds the tolerance level. The US Food and Drug Administration also addresses the Code of Federal Regulations, Title 21, Volume 8, Part 801 (www.fda.gov) it states:
“A number of devices currently on the market generate ozone by design or as a byproduct. Since exposure to ozone above a certain concentration can be injurious to health, any such device will be considered adulterated and/or misbranded.
Jury awards Marriott guest $120,000
Stephanie Tolson was a paying guest in a Marriott hotel in Arlington, Virginia on the evening of January 26, 1998. She complained of the smell of cigarettes in her room but was advised that there were no other rooms available and that an ozone machine would be employed to clean her room the next day. She was also informed that, for health reasons, she could not be present while the machine was running. Later that evening, Tolson was transported to the emergency room where she was diagnosed with acute pulmonary chemical irritation. Her family doctor examined her the following weekend and referred her for diagnostic testing, which revealed that Tolson was suffering from asthma and thickened vocal cords. Tolson was then referred to a board-certified occupational disease physician, Dr. Laura Welch, for an examination.
Tolson subsequently filed a lawsuit against Marriott for negligence.
Marriot denied any improper use of the machine.
The jury returned a verdict in favor of Tolson for $ 120,000.
Marriot appealed to the United States Court Of Appeals For The Fourth Circuit which upheld the jury verdict.

Conclusions: Whether in its pure form or mixed with other chemicals, ozone can be harmful to health. A business can be sued for a Non-Disclosure Health lawsuit for not informing a driver or guest that ozone was used. Ozone use in autos can instantly void the Manufacture’s Warranty. When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and lung irritation. Animal studies suggest that long term exposure to ozone may lead to permanent scarring of lung tissue, loss of lung function and reduced lung elasticity. It may also worsen chronic respiratory diseases such as asthma and COPD. Machines that generate ozone should never be used around the ill, infirm, young or elderly.
