Rated 4 out of 5★ by LegitReview Good overall PRO's:slowest speed is quietMedium speed is just a moderate background noiseTall skinny design may work well for certain space requirementsSignals when filter needs cleaning (how it determines this I don't know)reasonably pricedCON's:High speed is noisy and the base of the unit will vibrate/teeter a bit making more noise.Tall design means greater tipping over danger, which happened to me and seriously cracked the hard plastic of the case.OVERALLI can't say I noticed a huge difference from allergens because I don't suffer that badly.met my needs.I really wanted prof-source material showing that this HEPA filter removes fine particulate 2.5 PM and smaller from the air. I've read online that HEPA filters do, but I'm dubious because the filter on the unit doesn't look like much. 01/29/2013
Rated 5 out of 5★ by Richard3309 Thermapure - TPP240 I like the many flexible feature; especially the UV light you can turn on to kill germs and viruses, and the filter you can clean and reuse. It has a small footprint (takes less space at base) compared to many. I like that it is energy efficient. Speed 1&2 are quiet and 3 is more powerful. I like that you can turn the Ionizer on or off. I keep it on all the time. Great value compared to many. 09/17/2013
Rated 4 out of 5★ by amsric i really like it; but i really like it; but thought it covered more than 200 sq feet, not sure what kind of damage it will do to electric bill yet but I believe it's helping us breath better. 04/09/2013
Rated 5 out of 5★ by Highregard Great air purifier all around. I had originally bought this item at another store. I was online and spotted this at Walmart for $47.00 less. Since I had already used the other one for a short period of time and was very happy with it, I ordered 2 from Walmart, got a Discover card from them and am getting a $25 gift card from them. I think the product is great. It has three speeds and I like that the highest one is just loud enough that it helps me sleep. The product is greatly priced, not too big, and has all the features that I'm looking for. 12/12/2013
