Ionic air purifiers negatively charge the air around your room. these negative charges attach themselves to contaminants causing them to drop rapidly from the atmosphere in the room which increases the quality of the air greatly. Negative Ions technology has also been proven to help reduce stress and enhance alertness. High amounts of these ions are found in certain natural setting such as forests and near waterfalls. Negative ions contribute to the feeling of well being and they are getting more attention all over the world.
Very few human activities add small ions to the air while many of them lead to ion loss. Industrial pollutants, traffic-engendered smog, and the ducts of ventilation systems all strip negative ions from the air.
