Tools and Hardware Reviews of Blueair 402 Air Purification System
Customer Review: so far work well....
Summary: 5 Stars
I bought this air purifier last year from Amazon. This year, this air purifier decreases my allergy symptom significantly. This year I did not take any medicine so far. Comparing other brands, Blueair is the quietest one I have ever had except Sharper Image that has a problem with excessive Ozone creating. If you have an allergy problem, it is worth to use it. One problem was a setting location because the air direction is somehow odd. Air direction has left 45 which have a hard time to be located. Otherwise, it works for me!Customer Review: Works well and quietly
Summary: 4 Stars
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.
Customer Review: Great unit but larger than I expected
Summary: 4 Stars
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 compared it with a smaller unit (the 250E) and the 400 series works a lot better for a number of reasons (better filter, it charges the particles so that they stick to the filter, larger, etc.) Also, because of the design, you can put things like books on top of it if you want to since it takes in and output air from the sides. You can also place it against a wall, something you cannot really do with the smaller 250E as it has the filter on the back.
All in all, this is a great unit as it performs very well is very quiet and well made.
Customer Review: Ok for Light Smoking
Summary: 4 Stars
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).
Customer Review: 1st time Air Purifier Buyer
Summary: 4 Stars
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.
