Works well and quietly
By Jason Stevens
After reading reviews a number of places online, I decided to buy the Blueair products. In ended up sampling the 402, 501 and 601, and ultimately returned the 501 and 601 and replaced them with 402s.The 402 is truly quiet. This was an important consideration for me; the reason I returned the 501 and 601 was because they were noisy. The 402 has four fan speed settings. The fastest is unpleasantly noisy; I would not want to be in the room while the unit is in this mode. The next fastest, though, is *much* quieter. We usually leave the units in this mode. Sometimes we use the next-to-slowest mode, for example when I'm watching a movie and sitting in a chair right next to the 402. The middle two speeds are sufficiently quiet that I never feel like I need to use the slowest speed. (The 501s and 601s are unbearably noisy at any but the slowest setting - which is slower than the middle speeds of the 402. For 2/3 the price you can move more air, more quietly. Go figure.)The only downside to the unit is size. It is about the same size as a tower PC. It's tall enough not to easily fit under furniture, and it's airflow pattern (in one of the skinny vertical sides, out the opposite side) means that the best placement is with one of the long sides against a wall. If wall space is at a premium, it can be hard to find a place to put it.I haven't had the units long enough to replace the filters yet, but I have taken out the filters that came with them, and put them back in. It was very easy to do. After two months, only one filter is showing any visible dirt - but the house is *much* less dusty.

Quiet and Effective... Emphasis on Q-U-I-E-T!
By Marino Shauye
I did a ton of research before deciding on the BlueAir. You'll find that the Blueair, although maybe making a bigger dent in your pocketbook than other big-name air cleaners, is your best bet for a quiet room with clean air. I've tried many other brands who claimed to be "whisper-quiet" and the like, and so far, only the Blueair has lived up to its claim.If you put it on the HEPAsilent mode, you'll have to look twice to even see if it's on. And that's not an exaggeration! Even in this mode, you can see particles going into the intake, so it's still effectively cleaning the room. It also takes very little electricity, so it's no strain on your utility bill to leave it on all the time to maximize room air quality.The unit is rather large, as other reviewers have mentioned, but once you get it against a wall, or under a console table, you're good to go. The only other potential issue you may have is the blue LED which tells you the unit is on. I'm a light sleeper (hence requiring a very quiet air cleaner) and the LED was so bright that I had to cover it so I could sleep. A very minor issue which will only bother the most sensitive sleeper.The filters are very easy to change, and are also conveniently available on Amazon! They require a switch-out every 6 months, in addition to a quick vacuum of the ionizing brushes inside the machine. If you deal with odors, then try the SmokeStop filter. It's quite a bit more expensive, but it works wonders. My neighborhood had a methane gas leak, and the SmokeStop filter took all the odor and toxins out of the air. The room with the BlueAir was the only "safe" room I could be in. So I'm sure it handles cigarette smoke with ease.You won't go wrong if you invest in one of these. Oh, and a sidenote, I have 2 cats, and a cat allergy (as well as a myriad of other allergies), and the Blueair allows me to keep my kitties close, and get a good night's sleep!

By Penn Stater
I read a number of articles and opinions on air purifiers before choosing the Blueair 402. There are a number of quality machines on the market, but for the price and performance, this one seems to be the best. I have been satisfied with my purchase after 2 months.I don't have any miraculous stories about allergy relief, but do feel the the air quality has improved despite 2 cats and a dog.Fan noise: settings 1 and 2 are virtually silent. 3 produces a calming and constant whitenoise (I leave this setting on all the time, with no trouble going to sleep). 4 is a bit loud (best for maximum exchange, but while out of the room).Indicator light: basically a blue night light.Simple operation, just pick the speed setting. Only drawback is no change filter indicator.Well packaged and quick delivery from Amazon.
