Grasp the handle of each ozone plate from the back of the Living Air purifier and pull them one at a time out of the unit.
Wipe each metal plate with a damp cloth to remove surface dirt.
Scrub each metal plate and its ceramic tile with an old toothbrush dipped in hot water or about 1 ounce of ammonia diluted in a sink full of hot water. This removes any further dirt deposits.
Rinse the metal plate and ceramic tile in hot water.
Let the plates and tiles dry completely before reinserting them in the Living Air ozone air purifier. You can speed the drying process by wiping them down with a dry cloth immediately after rinsing.
