The Bi-Polar creates cold plasma discharge which consists of positive & negative ions from water vapor in the air. Positive & negative ions attach to particles & allergens such as dust, smoke, pollen & dander. Particles cluster together to create larger particles. Larger heavy particles drop out of the air and are easily trapped in filters. When the ions land on the outer shell of a mold, bacteria, or virus, the hydrogen is removed, the DNA is damaged and the pathogen cannot reproduce. Positive and negative ions attack odors and harmful VOCs on a molecular level converting them into harmless atmospheric gases, such as oxygen, carbon dioxide and water vapor. The balance of positive and negative ions neutralize static electricity.
