I’m totally stealing the description below from a completed auction because the guy did a terrific job explaining this item. My father-in-law used this religiously for years before upgrading. I’ve tested the item and it powers on with no apparent issues. Back filter can be touchy, in the lower right hand corner the plastic piece needs to latch on to the machine. It took me a few tries to get it to latch correctly. Includes two ozone plates. Want additional pictures? Feel free to shoot me your e-mail address with what you would like to see. Have any additional questions, feel free to ask!
