Working of ozone plate :-

Ozone plates produce ozone and clean the air in a large space, deodorizing, disinfecting and generally removing dangerous or irritating particles.

In the Ozone Blaster 14g and Ozone Blaster 2, ozone is created by applying high voltage to a metallic grid that’s placed between two dielectrics. These plates are referred to as ozone plates. So, for your ozone blaster to be working properly, its plates must be properly maintained.
