HOLMES HAP223-UC2 ODOR GRABBER WITH HEPA-TYPE FILTER

Comment: I picked up one of these for cheap and have been happy with it. It's best in a small room, like the specs say, and it does make a fair amount of noise on the higher setting. But it's pretty quiet on low and does really freshen the air. People changing the filter every month haven't read the instructions. There's a guide showing you only need to change it when it's black, it will still work when it's a little dirty. Plus I've stretched the filter life by vacuuming the filter and washing the sponge-like pre-filter. The filters are pricey to replace, but you should be able to go a year between replacements based on my experience -- and that's using it in a room with birds, where there's a fair amount of dust to clean.

Comment: If you have to replace the filter so often , can we ssume that is because the filter is dirty? Doesn't that mean it is removing some stuff from the air --which is what you want it to do???

Comment: I bought this product for a fan sound when I sleep since I like that sound for sleeping. If you expect it to really clean anything, guess again. It is a small noise maker only and does not do what it is supposed to do, but in all fairness, virtually no aircleaners at any price really clean the air of dust, etc. I got in on an Amazon.com special about a year ago and since the price was so low, it has been an excellent investment for my purposes.

Comment: Bought this on clearance and it was only worth the clearance price, in my opinion. Within 2 months, I had spent more on filters than I had on the actual purifier. No, it didn't clean the air well and it was very loud. I stopped using it after 2 months because it wasn't worth all the trouble of finding and buying the filters anymore.

Comment: For me this product works good but it needs a new filter every 1 1/2 months.
