Holmes Harmony Air Purifier, Extra-Large Room

I have owned this purifier for 9 months with no problems whatsoever. I find it very powerful and very effective in trapping dust in a large room but I actually use two of them in my living/diningroom of my apartment. I also use it in my bedroom where the area is smaller. I find it is quiet on every setting except the highest which isn't needed when sleeping. The larger the room, expect to change the filter more often. When having only one located in the livingroom, I was changing the carbon filter 3-4 times a year and the Hepa filter about 3 times a year. My advice would be that if you have rugs, vacuum often-this will prolong the use of the filter and control for dust. Update: August 24th 2009. I continue to own three of these machines and all are still going strong. Filters are expensive, but I am still sticking with them because they work so well. Using the purifiers only when home and turning them off when not will obviously also help to save on overuse of filters as well...Read more

This is a great unit, but I found it elsewhere for much less money. If you're buying online - compare prices.

This was rated one of the top air purifier and it didn't disappointed me at all. I would recommend this if you are looking to spend around 200 or below. I am planning on buying another one for my parents.
