Query: Don't buy this model. Honeywell screwed up!

I bought this air cleaner in March of 03 and was pleased with the thing until it just stopped working in January 04. There was no indication that anything was amiss, I was changing the pre-filters on the recommended schedule and then one morning nothing; no lights, no sound, no activity. Am sending it back to Honeywell (on my nickel according to their warranty policy). We will see how long the replacement lasts. I have read several reviews here that don't give me much hope. Amazon was nice, said I needed to contact Honeywell directly but suggested I post a review.
