Alright, I'm not sure the model at this moment, I know it's a "Plasma Aire" model with all the Hepa filters, color screen, remote with LCD display and everything... I paid $450 for it 3 years ago, used it TWICE, and when I say twice I only mean twice... It's been sitting around since I moved out of that apartment and don't wanna move it again... I'm asking $180 for it OBO!! It still has a warranty til Sept of '06 so it's set to go... I have all books and everything for it except the receipt... Bought it brand new at Sears in Brookfield square!!
