Query: Great value - works well

Originally I purchased an IFD air purifier. They simply don't work.To replace the IFD air purifier I purchase the Honeywell 17000. The unit works really well at removing dust and other airborn particles. The unit is not as "whisper quiet" as the model name would suggest - but I do not have trouble sleeping while it is on. It sounds like a small box fan on a low setting - which is not too bad at all really.For the price - I would highly recommend this unit over others.
