Query: Don't bother!!!

It's expensive and the ad on TV look impressive but don't be fooled. The unit will work reasonably well for awhile, but it is GIGANTIC PAIN TO CLEAN. There isn't really an more delicate way to put it. Truly, dealing with these units SUCKS HUGE You have to soak the cleaning cell for hours and hours, buy a ridiculously expensive cleaning agent and, and waste vast amounts of water to get this thing anywhere near clean. Then the Oreck people themselves recommend waiting up to 24 hours for the cell to dry. You can do all of this and then the damn thing starts popping (indicating that the filter should be cleaned again) just days or even hours later. It is maddening and I will NEVER buy another Oreck air cleaner. I won't even go into the amount of ozone they produce which is a very bad thing for folks like me that are asthma sufferers. There has to be a better item out there to keep you air fresh. Do your research and stay away from the ORECK.
