Blueair 402 Air Purifier Product Features

  • HEPASilent technology, exclusive to Blueair, combines mechanical filtration and electrostatic filtration for highly effective air cleaning that outperforms standard HEPA, capturing 99.97% of the tiniest particles at 0.1 micron. A layer of activated carbon adsorbs small particles and chemicals.

  • HEPASilent technology allows extremely quiet operation. The low-density filters clean large volumes of air more quietly than any other air purifier. On the lowest setting, Blueair air purifiers are about as quiet as the average desktop computer.

  • Exclusive SurroundAir technology draws dirty air in from all sides and gently diffuses air through an area six times greater than the average air cleaner.

  • EnergyStar rated low energy consumption saves you money on your power bill. In fact, it costs about the same to clean the air in your home as it does to power a single light bulb.

  • Optional Smokestop Filter has more activated carbon for enhanced removal of smoke, odors, and gases.

  • All Blueair products are environmentally aware and offer exceptional performance without polluting the environment. Blueair replaces standard filters (which can harm the environment) with safer, nontoxic polypropylene filters. In addition, Blueair air purifiers are coated with a special powder finish that produces no chemical off-gassing. The polypropylene filters also resist contamination from mold, bacteria, and viruses.

  • Unlike many electrostatic air cleaners, Blueair 402 air purifiers are safe for allergy and asthma patients because they release no ozone by-products.

  • Easy to Use & Maintain. Plug it in, select the speed setting, and forget it. To clean, simply wipe the steel exterior. When the filter needs to be replaced (every six months), just open the lid, lift the old filters out, and drop the new ones. No screws, no tools, and barely any time required.

  • The award-winning design is sleek and stylish, and the steel housing is durable and easy to clean.

  • Effective for room sizes up to 450 square feet.

  Fresh air at last!
Reviewed by: Pet lover with allergies from Broken Arrow, Oklahoma

I purchased this unit primarily for my allergies and to try to alleviate pet odor. I love my pups and getting rid of them was NOT an option. The unit is fantastic! It was put in our master bedroom as that's where most of the trouble lies. It is super quiet and, seriously, the pet odor is GONE! I can breathe! Another secret surprise: it gently blows out cool air which keeps our bedroom a nice temperature! What can I say? I love it!
  Very, Very quiet
Reviewed by: Cynthia from Williamsburg, VA

Love this air purifier! The first time my husband turned it on we were amazed at how quiet it is even at the highest setting. The filter is super simple to install and even though it is rather large it's has a very sleek and nice design to it, looks somewhat like a computer tower. Highly recommend.
  Quality and Style

After researching all th air purifiers, I bought a Blue Air. The first one I bought was a 501. I liked it so much I bought the 401 for the master bedroom. They are so quiet you can't even hear them run on lower speeds. I wish the 401 was on wheels like the 501.

Blueair 402:

I took the Blueair 402 home for a weekend test to put it through its paces and see how it operates in real-world conditions. My impressions of this unit are overall very positive. I put it in my living room adjacent to my kitchen where I have noticed some dust moving through the air when the sun shines through in the morning. I turned it on Friday night and ran it on high speed. After about an hour, I noticed that the air smelled fresher. The next morning, I turned the unit down to its second speed level while having breakfast, because it created a cool draft. After that, I repositioned the unit so that the supply was facing away from the kitchen and turned it back on high. In the warmer months, this unit will probably keep cool air circulating nicely throughout the room when left on high. After using it all weekend, I would recommend it to anyone who wants a solidly constructed unit that is easy to operate. The filter can be changed in seconds; you just open the side door like you would any cabinet in your house and the filter is right there. Another major plus is that a lot of air gets purified with minimal fan noise. On its slowest two speeds, you can't hear the fan. On its third speed, it's audible but not to the point where its bothersome. On high speed, you will hear it, but it's significantly quieter than comparable units.

What I like about the Blueair 402 Air Purifier:

  • Solid steel construction - this unit will last a long time and is backed by a 10 year warranty
  • Easy to operate with a large knob for changing speeds
  • Low noise
  • Easy to change filters
  • Ten year warranty

What I didn't like about the Blueair 402:

  • It weighs 34 pounds and needs to be on casters
  • Carbon (Smokestop) filter is optional
  • Requires filter changes every six months

In summary, I give the Blueair 402 five stars. Once you get it home and place it where you want it to go, it will work very well to purify the air in your home.
