According to a report published by Consumer Reports and backed by the American Lung Association, researchers found a direct link between ionic air purifiers and lung damage. According to the report, not only are ionic air filtration systems ineffective at cleaning the air, but the ozone emitted into the air while they operate can irritate the lungs, leading to shortness of breath, a worsening of allergies and, in extreme cases, ongoing respiratory problems and permanent scarring.
According to another article published by Healthy Living Answers, an online health information and consumer advocacy source, an increase in pain, burning and discomfort in the chest was also experienced by users of ionic air cleaners. Much like the symptoms of lung irritation, pains in the chest were reported by some individuals even at low levels of exposure. These side effects were backed by the Environmental Protection Agency in its report relating to the health effects of ozone in the general population.
Another common side effect reported by users of ionic air cleaners is burning and irritation of the throat. These side effects can range from mild levels of irritation to chronic pain. In addition to throat pain, users of ionic air cleaners reported extended periods of coughing and cold and flulike symptoms that were not responsive to traditional cold and flu medications. Another related side effect commonly reported was a chronic inflammation of airways connecting to the throat, which contributed to and worsened cases of asthma.
Another significant concern regarding the effects of ozone emitted by ionic air cleaners is its effect on cells. The Environmental Protection Agency's report on the the effects of ozone determined that a marked level of cellular damage was observed after only four to five days of exposure. According to reports published by Spiritual Endeavors, an online health advocacy and information resource, ozone has been shown to stimulate the body's production of Tumor Necrosis Factor (TNF), which can cause cancerous tumors to develop from seemingly healthy body tissue.
