I have an Austin Air Purifier in my office, because I have no window, and I do find it removes odors of perfumes, photocopying and such. Its also great in the heat, because it creates a 35 m/p/h breeze on the "high" setting. It cost about $700 Canadian when I bought it 5 years ago. The filters should be replaced every 5 yrs or so, but I don't have mine on constantly. I can't remember how much the filters are. Anyway, I do find it works in my stuffy office, and I can maintain a thought a whole lot longer and also keep a decent energy level happening. Might want to check them out - I don't know if there is a web-site, but I'm sure someone in your area must have a connection.
