How to know that my Ionic Pro air Purifier needs to clean?

The indicator light is green under normal operation and flashes red when the Collector Cell requires cleaning.

The red “WASH CELL” light will flash or illuminate when it is time to clean your Collector Cell. Your Air Purifier is still filtering the air when the red light illuminates.

It is not necessary to wait for the red “WASH CELL” light before cleaning the Collector Cell. Even if the “WASH CELL” light is not red, Oreck recommends cleaning the Collector Cell every 4 to 8 weeks, or more often if snapping becomes frequent.

Cleaning your Oreck Air Purifier is a snap too… and a must for efficient operation.
