Air purifiers are becoming more and more common, thanks to people who suffer from allergies. They are also needed in cities that are very polluted. Recently, the US embassy in Beijing ran out of adjectives to describe the air quality, so they came up with crazybad. How bad is crazybad? Pretty bad! That's why these new energy-efficient air purifiers are nice to have around. On top of that, they are also pretty silent.
The 270E is the latest iteration of the energy efficient air purifiers from Blueair. With an estimated power consumption from 20 to 80 W, depending on the settings, it definitely consumes little power. It's designed to clean up the air in rooms up to 210 sqf. This air purifier comes with a remote control. It's also quiet, operating at 32 to 56 dB. It currently sells for $400 at Amazon.
The Swedish-developed Humanair air purifier is supposed to be the world's most energy efficient. The manufacturer says that it only consumes 22 W of power. The Blueair 270E can consume as little as 20 W, but it will all depend on the average power consumption, not just the claims of the manufacturers. The Humanair seems to have similar specs to the Blueair. It's going to be available in January 2011, but there's no word on pricing.
