Description of Blueair 402 Air Purification System
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 designFor 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
Tools and Hardware Reviews of Blueair 402 Air Purification System
Customer Review: One word - Quiet!
Summary: 5 Stars
After having had a typical inexpensive air cleaner you can buy at most department stores for years, I was concerned about having a filter that was noisy. Our old filter was too loud to leave on even on the lowest fan setting. In fact we would sometimes turn it on for the sole purpose of providing background noise when our kids were sleeping.
I picked the Blueair 402 because of the great reviews that it got for being quiet and for the great ratings on how well it cleans the air. It arrived yesterday and I have been impressed beyond what I expected. I may have had low expectations because of my old filter, but when I first turned it on I had to check to make sure that it was even running because I could not hear it at all! On the lowest two settings the sounds is not even noticeable. On the third setting you can hear it running, but the sound has a much better quality than other filters/fans. Even on the highest setting the noise it not that objectionable (quieter than my old filter on the lowest setting.) I wouldn't leave it at this setting for sleeping, but I wouldn't have any problem leaving it at this setting during the day, especially in a room I was not in.
We left it on setting three all night without a bother (I may consider using setting two after our initial "cleaning" period is over. My wife and I both felt a noticable difference when we woke up this morning. Part of the reason for getting this is that we have a dog and two cats and we were both waking up in the morning all stuffed up and/or sneezy. This morning was noticeably better.
The filter is very easy to replace also. The one downside is that the unit is rather large. As long as you know this going in, it shouldn't be a problem. Unless you have a very large area you are cleaning, you may want to opt against the 501 or 601 as I believe they are even bigger. I may consider getting a 201 for my kids' rooms since they are smaller bedrooms.
Overall I'm very pleased and also like the fact that the filters are environmentally friendly compared with some of the filters used in other units.
