The oreck air purifer works great at cleaning the air you breath but when it comes to cleaning the collection grid and panels you can either do a poor job and have to clean more often or try and clean throughly and run the risk of bending or breaking very delicate wires the run accross the ion panels. I had trouble and had to replace the ion panels due to that fact that if bent the wires that run across the panelsĀ causeing them to arc on them selfs and this doesn't allow the machine to work. Now I am forced to clean repeatitly becuae I am affriad to damge the machine again.
