Average Reviews:
(More customer reviews)First off I am amazed at how quiet it is. It is only loud on the highest setting, and even that is bearable, it is similar to running a box fan on high. However, as soon as you switch to the next setting down, it is much quieter, about the sound of a low fan or in some cases the sound AC makes when running - I think this is a great setting still good air flow but much too quiet to disturb anyone. The next two settings down, I literally CANNOT HEAR AT ALL! Specifically the next one down, I can only hear if I put my ear up close to it, and the lowest setting, "HEPA silent" I had to feel the airflow to be sure it was running. This is great, compared to my other air purifier (Honeywell 50250N) it is much quieter - it's second highest speed setting is as or more quiet than the lowest setting on my Honeywell, and it is also designed to cover a larger area and has a special filter option for filtering smoke.
I've only just bought it and ran it one day, so I can't say yet for sure how well it will filter the air, but so far it seems to be doing a good job, the air smells fresher and I haven't noticed the occasional smoke order - I'll be able to tell better when it gets colder and the people in the apartment below me and around me smoke more indoors. The reason I got it was particularly to deal with the chain-smoking idiots who live below and around me - whenever it gets cold they pretty much smoke constantly inside their apartment, and all the smoke seems to get filtered by the apartment building design into my apartment. I may update this review after I've used the purifier for a few months.

Providing five air changes per hour in rooms up to 580 square feet, this sleek-looking air purifier effectively delivers healthier indoor air--ideal for people living with allergies, asthma, or other respiratory conditions, or for anyone who wants cleaner, more breathable air. Its HEPASilent technology uses electrostatic and mechanical filtration to quickly and quietly capture 99.97-percent of particles down to 0.1 micron in size, including allergens such as pollen grains, dust mites, mold spores, and pet-dander particles (CADR rating of 375 for smoke, dust, and pollen). Even more, its three-stage progressive filter traps up to six times more dirt than competitive models. The unit also reduces annoying drafts thanks to its SurroundAir system, which draws in dirty air from the sides and bottom, moves it through the filter, and then gently diffuses clean, filtered air from the sides and top. Choose from three speed settings: HEPASilent for nighttime use, moderate fan speed for daytime use, or maximum fan speed for fast initial cleaning or very polluted air. Each setting offers quiet operation, which makes the air purifier ideal for in a bedroom or office.
Other highlights include galvanized steel construction, a blue "power on" light, a digital filter-replacement indicator, and easy maintenance--just open the lid, lift out used filters, and drop in replacements at least once every six months. Made of nontoxic polypropylene, the 100-percent-recyclable filter media produces only carbon dioxide and water as it decomposes, plus it's waterproof, which makes it naturally resistant to bacteria, viruses, and mold, without chemical additives or washes. Best of all, the appliance has earned an Energy Star rating, which means it meets strict energy-efficiency guidelines set by the EPA and U.S. Department of Energy. Energy Star products can help save up to a third on energy bills, as well as greatly reduce greenhouse gas emissions, all of which means more comfortable indoor air without excess costs or impact on the environment. The air purifier measures 13 by 20 by 26 inches and carries a five-year limited warranty.
