Indoor air purifiers or ozone generators may pose a serious health risk to people who may be affected by ozone. A study revealed that running the air purifier at the top setting produced an ozone presence in the room that was the same as a stage one smog alert which means that people are advised to avoid the outdoors. Even a medium setting on the purifier produce ozone levels above the California state standard. Of bigger concern is that air purifiers are particularly targeted at people with asthma and other respiratory problems but the ozone generated can make symptoms worse by damaging cell linings in nasal passages and lungs. High ozone levels can cause symptoms such as pain when breathing deeply, coughing and chest tightness. The purifiers claims to remove bacteria, mold and chemical contaminants and thus may benefit asthmatics are misleading.
