All corona treaters emit ozone as a by-product. Ozone, chemically speaking, is O3. O3 is heavier than O2 and is extremely corrosive. Discharging ozone to the environment is damaging to the local environment as well as the larger environmental concern of the ozone layer!

OZO-NO! is a multi-stage catalytic ozone destruction system which effectively reduces O3 to O2 in accordance with EC rule 92-72.
