I purchased the Ionic Breeze Quadra air purifier with Ozone guard from e-bay. Happy as a clam because I got a good deal, I didn't ask about the User Manual. The seller either didn't have one or didn't send it with item. I really think the product is doing a wonderful job, but I'm not sure how to maintain it properly. A user manaul is gold and I wont be purchasing anymore items like this on e-bay if the seller doesn't have the manual. Any help with getting a copy of the manual will be greatly appreciated.
