Harmful Effects of Air Purifiers

time2011/11/03

   Indoor air purifiers are devices made to clean the air of common indoor and outdoor pollutants such as ozone, mold, pollen, dust and pet dander. The HEPA air purifier is considered the best on the market and is 99.97 percent effective according to Happy Living. Other air purifier systems may lack in effectiveness for various reasons; nitrogen purifier that use ozone instead of HEPA filters have been found to cause harmful effects on people's health.
Air Contaminants  
   Certain air purifier companies claim to remove toxic indoor pollutants. Ozone is a common indoor and outdoor highly reactive gas composed of three oxygen atoms. Exposure to ozone is dangerous. This ground-level ozone is harmful when it reacts between two major classes of air pollutants: volatile organic compounds and nitrogen oxides---mostly emitted from man-made pollutants (gasoline, chemical plants and other industrial product). According to MSNBC Consumer Reports, nitrogen purifiers are supposed to remove certain toxic levels of troposphere ozone from an indoor environment. However, the Consumer's Union in 2005 found certain air purifiers are ineffective in removing airborne ozone pollutants.

   When the third atom on the ozone detaches itself from the other two atoms, it reattaches itself to the molecules of other nitrogen purifier substances, changing their chemical composition. The air purifier system is not capable of reconfiguring the chemical composition of the ozone molecule. Therefore, any claims that an air purifier removes or filters out ozone pollution is debatable.
