Best overall air purifier

Blueair Pure 411

CNET TAKE: The Blueair Pure 411 is a simple, straightforward purifier with smart design and solid bang for your buck. You get particle and carbon filtration (which removes odors and gaseous pollutants) that will work well in a 160-square-foot room, all for $120. Some devices, like Sharp's Air Purifier, don't even offer that much cleaning power at nearly twice the price.


The Blueair has different colored prefilter sleeves for the outside of the device, so it will fit into almost any color palette, and its single-button interface is as intuitive as it gets. The device is also light, with middle-of-the-road noise production. Besides the noise, the only real downside is the lack of extra goodies, like timer buttons.
