The Texas EPA states that because of Texas' prominent position in petrochemical refining that the State of Texas is the state with the highest ground-level ozone levels and are undertaking steps to control ozone generation at ground level because of its health hazards even at parts per billion.  Similarly, California created the CARB agency to reduce ground level ozone now has a ban on all ozone generators (source: L.A. Times).   Many states are beginning the legislation to ban the ozone generators.  Below are only a few of the pertinent web sites from several states.  Illinois, New Jersey, New York and Ohio are also looking at this issue.  The State of Connecticut, The Federal EPA, and California EPA have scientific testing that show the ozone generators control odor, by "deadening the sense of smell," which has been confirmed in testing.  However, a week later the odors came back (concurrent when the residual ozone left the cars.)   I hope the information is helpful.

http://www.dshs.state.tx.us/iaq/SchoolsGuide.shtm#Ozonegenerating
see item letter: (m) Ozone-generating devices. Ozone-generating devices should not be used in occupied spaces. Ozone is a lung irritant.
(the city of San Antonio has banned ozone generators in all new buildings)

#2) OSHA (US GOVERNMENT)
http://www.osha.gov/dts/osta/otm/otm_iii/otm_iii_2.html
II.B.6:  "Sources of Ozone: Copy machines, electrostatic air cleaners, electrical arcing, smog.      Acute health effects:  Eye, respiratory tract, mucous membrane irritation; aggravation of chronic respiratory diseases."

#3)  FLORIDA DEPARTMENT OF HEALTH:  
http://www.doh.state.fl.us/WildfireSmokeFAQ.doc (MS Word)
Some devices, known as ozone generators, personal ozone devices, “energized oxygen”, “triatomic oxygen”, “activated oxygen” and “pure air” generators are sold as air cleaners, but they are not recommended for use in occupied buildings. Ozone does not remove particles from the air, and would not be effective during smoke events. Ozone itself is toxic and a regulated outside air pollutant. We advise the public to avoid exposure to ozone indoors by not using air cleaners that produce ozone.

#4)  US NUCLEAR REGULATORY COMMISSION 
http://www.policyalmanac.org/environment/archive/ozone.shtml
"Even when ozone is present in low levels, inhaling it triggers a variety of health problems including chest pains, coughing, nausea, throat irritation, and congestion. It also can worsen bronchitis, heart disease, emphysema, and asthma, and reduce lung capacity"

#5)  EPA
http://www.epa.gov/iaq/pubs/ozonegen.html
"Contrary to the claims of some vendors, no agency of the federal government has approved these devices for use in occupied spaces. In fact, when ozone is inhaled, it can damage the lungs. Relatively low amounts can cause chest pain, coughing, nausea, throat irritation, and congestion. It may also worsen bronchitis, heart disease, emphysema, and asthma, and can compromise the ability of the body to fight respiratory infections. Although manufacturers and vendors of ozone generators may describe ozone as "energized oxygen" or "pure air," ozone is a toxic gas with different properties from oxygen. In fact, several federal agencies have established health standards or recommendations to limit human exposure to ozone. Scientific studies have shown that when ozone concentrations do not exceed these public health standards, ozone has little potential to remove indoor air contaminants. Particles such as dust and pollen that cause allergies are not removed by ozone. Ozone is also not effective at removing many odor-causing chemicals, nor does it remove viruses, bacteria, mold, or other biological pollutants. The public is advised to use proven methods of controlling indoor air pollution"

#6)  AMERICAN LUNG ASSOCIATION  
http://www.epa.gov/iaq/pubs/ozonegen.html
"It can have damaging health effects, especially for persons with asthma and other lung diseases, children and the elderly. It is produced directly by ozone generators and indirectly by ion generators and some other electronic air cleaners. The American Lung Association suggests that ozone generators not be used."

#7) NATIONAL INSTITUTE FOR ENVIRONMENTAL HEALTH 
http://www.niehs.nih.gov/health/topics/agents/ozone/
"No federal agency approves, much less recommends, ozone generators for use in occupied spaces."

#8)  CALIFORNIA HEALTH DEPARTMENT
http://www.arb.ca.gov/research/indoor/o3g-list.htm
The State of California has approved a ban on ozone air purifiers (9/28/07).
"People should avoid using indoor air cleaning devices that produce ozone, sometimes referred to by marketers as activated oxygen," said Jim Stratton, M.D., M.P.H., State Health Officer."
"Although ozone generating machines are promoted as air cleaners, independent studies have shown that the machines do not effectively destroy microbes, remove odor sources or reduce indoor pollutants sufficiently to provide any health benefits. The Federal Trade Commission has recently taken action against some manufacturers of ozone generating machines for making unsupported claims about the ability of the machines to clean air."

#9)   MINNESOTA HEALTH DEPARTMENT  
http://www.health.state.mn.us/divs/eh/indoorair/mold/
"Some air cleaners are designed to produce ozone which is a strong oxidizing agent and a known irritant of the lungs and respiratory system. Studies have shown that ozone, even at high concentrations, is not effective at killing airborne mold or surface mold contamination. Health experts, including the Minnesota Department of Health, do not recommend the use of ozone to address mold or any other indoor air problems."

#10)   NORTH CAROLINA HEALTH DEPARTMENT  
http://www.epi.state.nc.us/epi/oee/ozone/ozonewhitepaper.pdf
"Ozone air pollution has been reported to be associated with an increase in hospital visits related to asthma, pneumonia, and otherrespiratory diseases. This was reported for several areas in the United States, Canada, and Mexico ."

#11)   NATIONAL NETWORK FOR HEALTH
"Ozone is a molecule composed of three oxygen atoms. It is a highly reactive chemical that is sometimes used to clear pollution in unoccupied buildings. It is also a strong lung irritant. People with asthma can be especially sensitive to ozone, and it can bring on attacks"

#12)  VERMONT DEPARTMENT OF HEALTH  
http://healthvermont.gov/enviro/indoor_air/Ozone.aspx#four
"Although some manufacturers of air cleaning equipment have claimed that ozone generators can decrease volatile organic compounds (VOCs) in the air, research has shown that such devices may, in fact, increase some types of VOCS. If an air cleaning device produces ozone at a level that is effective in killing molds and viruses, then it is also at a level that can be harmful to human beings and pets.
Inhaling fairly low amounts of ozone can result in signs and symptoms such as coughing, congestion, wheezing, shortness of breath, and chest pain in otherwise healthy people. People with already existing asthma, bronchitis, heart disease, and emphysema may find their conditions worsen while inhaling ozone. Breathing ozone may also increase the risk of getting certain lung diseases."

#13)  WISCONSIN HEALTH DEPARTMENT  
http://www.dhs.wisconsin.gov/eh/Air/fs/AirCleaner.htm
(see last page of doc)  "Air cleaners employing electrostatic precipitation or ion generation may produce ozone, a gas that can irritate the lungs. Production of ozone may be particularly high if the air cleaning system has been improperly installed or maintained. The Department of Health and Family Services (DHFS) does not recommend using air cleaning machines that operate by producing ozone."


#14)  MISSISSIPPI HEALTH DEPARTMENT 
http://www.msdh.state.ms.us/msdhsite/index.cfm/43,323,283,331,html
(see last page of doc)  "Some air cleaners are designed to produce ozone. Ozone is a strong oxidizing agent used as a disinfectant in water and sometimes to eliminate odors. However, ozone is a known lung irritant. Symptoms associated with exposure include cough, chest pain, and eye, nose, and throat irritation. Ozone generators have been shown to generate indoor levels above the safe limit. Furthermore, it has been demonstrated that ozone is not effective in controlling molds and fungi, even at high concentrations far above safe health levels. Also, ozone may damage materials in the home. For these reasons, the Mississippi Department of Health strongly recommends that you do not use an ozone air cleaner in any occupied residential space."

#15)   ARIZONA HEALTH DEPARTMENT
http://www.azdhs.gov/phs/oeh/invsurv/air_qual/moldcleanup.htm
"ozone is not effective in controlling molds and fungi, even at high concentrations far above safe health levels. Also, ozone may damage materials in the home. For these reasons, the Arizona Department of Health Services strongly recommends that you do not use an ozone air cleaner in any occupied residential space."
