Learn about the negative effects of ozone in air purifiers
Shown below are excerpts from a variety of reports about ozone dangers.
From the State of Florida Dept of Health:
Do air-purifying machines help remove smoke particles inside buildings?
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.
From the US Nuclear Regulatory Commission: How Does "Bad" Ozone Affect Human Health and the Environment?
Repeated exposure to ozone pollution may cause permanent damage to the lungs. 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.
From the State of California Health Department:
"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. "These devices can quickly produce enough ozone in a confined space to exceed the California Stage 2 and 3 smog alert levels as well as worker health and safety standards."
Ozone is the primary chemical that makes up smog and can produce a variety of health problems. Long term exposure to high levels of ozone may result in permanent lung damage. Ozone can also cause eye, throat and nose irritation and increased sensitivity to airborne irritants.
From the Mississippi State Department of Health:
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 State Department of Health strongly recommends that you do not use an ozone air cleaner in any occupied residential space.
From the Arizona Dept of Health Services:
