1. The dirty air first passes through a pre-filter. Large particles of oil are filtered.
2. The air then passes into the high voltage ionise section where the particulates are charged to a positive potential. And then the air passes into low voltage collector cell
section where the particulates are charged to a negative potential. So the particulates are attracted to the collector plates effectively.
3. The particulates remain on the plates or drain down in to the sump.
4 UVC-ultraviolet light produces OZONE and undergoes chemical processes such as Photolysis and Ozonolysis that breaks down grease and odour containing compounds
produced during cooking.
5. The cleaned air exits through the cabinet.
