The Bi-Polar 2400 does not produce ozone. Instead it incorporates Bi-Polar ionization, also known as Cold-Plasma technology. Bi-Polar ionization uses low-voltage electricity and water vapors to create both positive and negative ions. These ions travel throughout your space and attach themselves to contaminants such as mold spores, allergens, bacteria, and viruses. Once attached to the contaminant, they then deactivate and kill off the particulate. Once the contaminants have been deactivated, they then fall to the surface leaving your air clean and free of harmful irritants.
