Product Description

Product Description

Blueair is the system for people living with alergies, asthma or other respiratory conditions, or for anyone who wants cleaner, more breathable air. A revolutionairy combination of advanced filter media and an encapsulated ion particle charging chamber makes it possible for the Blueaur air purification system to achieve better results than either technology alone. Our patented HEPASilent filter technology is proven effective at capturing 99.97% of the tiniest 0.1 micron particles. The quietest unit in the industry, Blueair's low-density filter clean larger volumes of air more quietly than any other unit in the industry. Hence the name HEPASilent(r) a Blueair Exclusive. Bacteria-resistant filters, Blueair's filters are made of bacteria-resistant polypropylene. Because polypropylene is waterproof, the filters naturally reist contamination from bacteria, viruses and mold without chemical additives or washes. And the filters only need replacement every six months, a process that takes under 30 seconds. The Blueair 501 is for room sizes up to 365 square feet.10 year limted warranty, Award-winning Swedish design

For rooms up to 365 square feet, this air purification system features two-stage HEPASilent technology that captures 99.97-percent of 0.1 micron particles, including allergy-provoking pollen grains, dust mites, mold spores, and pet dander particles. Particles that a HEPA filter alone might miss are captured with an electrostatic charge. HEPASilent technology moves particles through an enclosed ion chamber, which attaches a charge to the particle itself. Charged particles cling more easily to the filter media, resulting in higher filter efficiency overall. Because most electrostatic air cleaners charge the filter media itself, the charge dissipates over time and renders the filter less efficient. By constantly charging incoming particles, instead of the filter, HEPASilent technology keeps on working effectively.

The air purifier's nontoxic polypropylene filter contains millions of ultra-thin fibers that trap tiny particles as they pass through the pleats. One of the least harmful plastics for human health and the environment, polypropylene works without outgassing or shedding irritating microscopic fibers into the air. Because polypropylene is waterproof, the filter resists contamination from bacteria, viruses, and mold naturally, without chemical additives. And as used filters are discarded and decompose, the filter media converts into harmless carbon dioxide and water.

Not only does the unit clean air with filters, it’s HEPASilent filter technology also allows for extremely quiet operation. On the lowest setting, the unit emits no more sound than a desktop computer. With its HEPASilent filter technology, particles are trapped with both mechanical and electrostatic filters so that in combination, the two filters create a filter system through which air flows freely and the fan doesn't have to work so hard. The unit's design is also geared towards quiet operation with its noise-muffling steel housing. Not only quiet, but the air purifier is energy efficient as well, using less power than a 20-watt light bulb, or 80 watts on high.

The air purification system operates efficiently, quietly, as well as inoffensively. Instead of discharging a windy stream of filtered air, the unit diffuses air gently through an area six times greater than the average air cleaner. Its SurroundAir system achieves peak performance without annoying drafts by drawing in dirty air from the sides and bottom, moving it through a less dense filter media, and releasing clean, filtered air from the sides and top. Operating on its lowest setting, the system produces virtually no noticeable draft, while still providing an exceptional air exchange rate.

The air purifier features a sleek, contemporary, Swedish design and is easy to use and maintain. Simply plug it in, select the speed setting, and it is ready to go, with a bright blue power "on" light to show that it's working. The grilles and powder-coated steel exterior are easy to wipe clean, and when the filter needs to be replaced (twice yearly), just open the side, slide out the old filters, and drop the new ones in. This quiet, efficient, easy-to-use air purifier measures 23 by 20 by 11 inches and carries a 10-year warranty. --Catie Unger

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.

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!

Verified Purchase
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.
