I really like having this and feeling like it's doing something.  I currently have one in our very open family room (center of house) and it's a pretty large area, but I have dusted it off a little.  I'm going to try moving it to the kitchen even though it's open too, just to see. I saw where a lot of people asked about a filter and I was confused to since it shows one to purchase with it, but it doesn't have a filter because I opened mine.  I found this on the purchase page where it actually says no filter.
