I bought the Honeywell HEPAClean Tower Air Purifier HHT-080 mainly to use in the spring/summer/fall because in the winter I use a humidifier that filters the air. So being I have two dogs, I thought that especially having a HEPA type air purifier would really help the air quality of my home. It does a pretty good job but note that it will not keep up with all rooms. I suggest having several if you really want to see a difference in the air quality. Also, not sure why, but it left a dark mark on my carpeting where it blows the air out so beware of that. All in all I have been please with the air purifier and even bought a second one for the bedroom area of my home.
