Every OdorFree ozone generator comes with 1, 2, or 3 ceramic plates depending on the model. They are the heart of the unit and create the ozone. They easily slide out the back of the unit like a CD for cleaning every 3 to 4 months with regular use. Just wash with detergent or spray cleaner, rinse with hot water and dry completely. All ozone generators will require periodic cleaning of the ozone producing element. After 3 to 4 months of routine usage an invisible film can build up on the ceramic plates. This film will prevent the OdorFree from producing the maximum amount of ozone. Reduced ozone production indicates it is time to clean the plates. If treatments are not as effective as they initially were, or the smell of ozone is not detected after the treatment, the ozone output has probably diminished and the plates need to be cleaned.
