Ozone: The Dangerous Affects From Using Ozone Machines To Remove Odors From Vehicles. Including Photos.

Can Ozone be Used in Unoccupied Spaces?
Ozone has been extensively used for water purification, but ozone chemistry in water is not the same as ozone chemistry in air. High concentrations of ozone in air, when people are not present, are sometimes used to help decontaminate an unoccupied space from certain chemical or biological contaminants or odors (e.g., fire restoration). However, little is known about the chemical by-products left behind by these processes (Dunston and Spivak, 1997). While high concentrations of ozone in air may sometimes be appropriate in these circumstances, conditions should be sufficiently controlled to insure that no person or pet becomes exposed. Ozone can adversely affect indoor plants, and damage materials such as rubber, electrical wire coatings, and fabrics and art work containing susceptible dyes and pigments (U.S. EPA, 1996a).

The Fact is:
Ozone will damage and destroy an automotive interior in a very short time this is why we do not recommend the use of Ozone or ionizing machines inside any vehicle or motor home because its like exposing the interior to the sun for 10 years. There are to many liabilities.
Ozone Damage on a 1 year old vehicle it destroyed the rear shelf and rotted the plastic.
Ozone Damage on a 1 Year Old Vehicle the plastic shelf is crumbling.
Ozone damaged auto interior it destroyed the seat belt guide.

Ozone-Generating Air Cleaners and Indoor Air ChemistryOzone-generating air cleaners are marketed to homeowners as well as business establishments ostensibly to remove odors and other contaminants from indoor air. IEMB has characterized ozone and oxides of nitrogen (NOx) emissions from these devices in full-scale environmental chamber tests and characterized performance in a research test house. To date, findings demonstrate that, for those models tested, ozone generation rates are generally within the ranges stated by the manufacturers and some models have the capacity to generate ozone concentrations of 200 parts per billion (ppb) in the test house, well above EPA’s 8-hour ambient ozone standard of 80 ppb. Additionally, ozone and nitrogen dioxide emission rates increase with decreasing relative humidity, and the relationship between ozone emission rate and NOx generation rate varies between different models of different manufacturers. Ozone-generating air cleaners equipped with an ozone sensor/controller designed to prevent activation of the ozone generator at concentrations above 50 ppb performed erratically in full-scale chamber tests but appeared to perform as designed in limited short-term (24 h) tests in a research test house. We conclude that more extensive testing is needed to characterize the sensor/controller. However, tests in the research test house clearly demonstrate that these devices are capable of producing ozone concentrations well above those of accepted health guidelines. IEMB is currently investigating the impact of ozone generators on concentrations of volatile organic compounds (VOCs) in indoor environments. These experiments investigate the chemical reactions that take place when an ozone-generating air cleaner is operated in the presence of emissions from a typical source of VOCs, such as an air freshener or cleaning product. Results demonstrate that the ozone-generating air cleaners have little impact on airborne concentrations of solvents used in consumer products, but do impact concentrations of many of the fragrance compounds emitted by this type of product. Reaction products include formaldehyde and other oxygenated organics. The interaction between ozone and some of the product emissions, such as terpenes, triggers formation of ultrafine particles. IEMB is currently refining analytical approaches to better characterize the “soup” of particles and gases that results from operation of these devices in the presence of VOCs.
