This is a great unit but it larger than I expected. If you have a small bedroom or office, it may look a bit imposing.
It runs very quiet at the two lowest settings and even at the third setting, I found the sound soothing enough to sleep with!
On the negative side, it has no electronic timer, remote or digital display like some of the other units have. It's also quite cumbersome and heavy to move and includes no caster wheels to make that easier.
On the plus side, it works very well and is more efficient and quiet than smaller units. The design is also more proven.
I bought the 402 with the Smokestop filter as I smoke about 3 cigars a week in my apt in the wintertime. This model is good enough for my purposes, but if you smoke more than that I'd suggest the 501 instead.
As others have noted, the 402 is silent on settings 1 and 2 and produces about the same amount of noise as a tower PC fan on setting 3. Setting 4 is noisy so I switch to that setting just before I leave for work if I've smoked the night before. When I return at the end of the day there us usually little or no smoke smell.
I'd estimate the Smokestop filter to contain about 3 pounds of activated charcoal. Much more than the thin layer found in most filters.
The unit itself is very well constructed and for an air filter it looks stylish. Access to the inside for the occasional vacuuming and filter change is extremely easy (large hinged side door).
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.
I was initially very disappointed after purchasing a factory refurbished 402 unit. It was very noisy which surprised me after what I had read online. Then I was in a local store with same unit on display and found it was much quieter. So I returned the "refurbished" unit and got a new 402 to replace it. Wow, what a difference. I literally can not hear the new unit on setting 1 (hepa-silent) and setting 2 is barely audible and does not disturb this very sensitive sleeper. In contrast my "refurb" unit was as loud on hepa-silent as the new unit on setting 3. So beware of getting a refurb unit as the quality control in their refurb department appears lousy. Additionally the refurb unit I received came with a torn filter. I will say however that the company was easy to deal with regarding problems. My only concern now is how well these units hold up. If my new unit becomes as noisy as that bad refurb unit over time I will not be happy.
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!
