While many air purifiers do a good job at cleaning the air, it's not what they take out that should be of concern, but what some re-emit back into the air: ozone. Ozone is an air pollutant that the EPA says can cause chest pain, coughing, shortness of breath and throat irritation. Some air purifiers are so bad that the EPA has advised consumers against using them. The simplest tip is to avoid using these so-called "air purifiers" altogether and use common sense instead. On a breezy day, open the front and back windows of the house to cross-ventilate the air; the "wind" tunnel effect will flush the toxins out.
