 Great quiet air purifierJun 08, 2009
By Mediahound
Some of the online specs are misleading. The Blueair 403 unit (at least the one I received) actually has 4 speeds, just like the Blueair 402! Even the manufacturer's own website as of this review lists it as having only 3 speeds. The only difference between the 402 and 403 is that the 403 comes with a small electronic timer that is magnetic (you can put it on your refrigerator or on the Blueair unit itself) which shows you when 6 months are up and it's time to replace the filter. This is handy, but not really needed. So, if you can still find a 402 (now discontinued) for a good price, I'd recommend you grab it!
This is a great unit but it is a bit 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. In fact, the first night I had it, I put it on the 3 speed setting and found the sound quiet nice and relaxing.
It works very well and is more efficient and quieter than smaller units. The design is also more proven; I compared it with a smaller unit (the 250E) and the 403 works a lot better for a number of reasons (better filter, it pre-charges the particles so that they stick to the filter, and has a larger, thicker filter). The 403 also has a deeper, more soothing and relaxing sound than the smaller unit. Because of the design, you can put things like books on top of it if you want to since it takes in and outputs air from the sides. You can also place it against a wall, something you cannot really do with the smaller 250E unit as it has the filter on the back and outputs air out the top. Also, larger units like the 500 series output air out the top (and sides) so you would not be able to put something on top of those either. I'm not saying I would use my Blueair 403 as a bookshelf or anything, just that it can be convenient to place a magazine or book or two on the top surface at times.
I will now buy a second 403 unit for my living room because I am so impressed. Having two or more of the same series in different rooms throughout the house seems a benefit as you only have one type of filter to buy for them all. However, if your living room is on the large side, you may need a larger unit (such as the 500 series so check your square footage). Note that the 500 series is *much* louder though.
All in all, this is a great unit as it performs very well is *very* quiet and well made. I feel I sleep much better with this unit on and also have much less allergy symptoms including less red and itchy eyes. Even if you don't suffer from allergies, you can still benefit from having nice fresh air all the time. My guess is that you will sleep better and feel more rested when you wake up. As for myself, the Blueair has practically been a lifesaver-I feel a lot more healthy and my allergy symptoms are virtually gone!

Quiet Enery Efficient and it Works!Apr 08, 2010
By P.W.

I should start with the fact that everyone in our household has allergies, even the dog I think, but that had not been confirmed. Currently we have the Blueair units in all the bedrooms and family room. The best thing about Blueair units is they work! We really feel a difference. Before getting Blueair my wife was not able to sleep thru the night. She would get congested and her throat would get dry so she kept waking up to drink water. Whatever was giving her trouble is now gone from the air and she is finally able to get a good nights sleep.
Outside the fact that this unit cleans the air, I do also like that it is steel construction ( I did a lot of research and that is hard to find), its quiet!!!, and its energy efficient. As for warranty, the warranty card says mail in for free 5 year warranty.

Every morning I woke up with my eyes swollen almost shut due to allergies since I got the Blueair 403 HepaSilent air purification system, my eyes are no longer swollen. My sinus problems have greatly improved. I am very please with how quiet it is- I can sleep with it on the 2nd level. I would buy this product again.

Solid construction, energy efficient, and truly quietOct 30, 2011
By David
When my allergist advised I put an air purifier in the bedroom, I wondered how I could find something quiet enough to fall asleep with. He recommended the Honeywells for their air quality, but reviews indicated these were pretty loud.
So, I first purchased the Whirlpool Whispure Air Purifier (AP51030K) based on Consumer Reports and Amazon reviews. From the moment I turned it on, I knew there was no way could I fall asleep with that in the room. Even on the lowest setting, it is quite loud: I could hear it just fine from 30 feet away in another room, through two open doors. In addition, it uses a lot of electricity - about 60 watts on the lowest setting. Finally, construction is a bit cheap: plastic and styrofoam.
Further research pointed to the Blueair series as quiet and energy efficient. Of these, the Blueair 403 is ranked the quietest. I ordered it and am very happy. It is extremely quiet on its lowest setting - just barely audible from 8 feet away in bed - and uses only 20 watts on the lowest setting. It's solidly constructed of metal, and well worth the higher price vs. the Whirlpool.
Regarding the Blueair 503, which I haven't tried: The 503 seems to be a better deal (just a little more expensive, rated for 50% more space, and - surprisingly - cheaper filter replacements). But the 403 is rated much quieter (27db vs 35db on lowest setting). I am considering getting the 503 for the living areas, which are larger and where noise is less of an issue.
Bottom Line: I love the Blueair 403 in my bedroom. The unit is quite large (11d x 20w x 23h), but well worth the space and price - given its silence, energy efficiency and stylish construction.

Solid, simple, quiet, effectiveApr 23, 2010
By Gary D. Heinz
The title pretty much sums it up... I took it out of the box, plugged it in, switched it on and don't really think about it anymore.
I live on a busy street and the air inside the house was very dusty.
With this thing running it is substantially cleaner ....
even when sunlight streams in I cannot see any dust in the air.
At highest setting it is audible but not objectionable. I keep it at max minus one and don't hear it at all.
It showed up with a small dent in the side, which I should have complained about but didn't.
The shipping package could have been better.
