The way we were
Last reviewed: May 2011
No air purifier alone can relieve asthma and allergy symptoms. But our tests of the Sharper Image's Ionic Breeze (shown) found
that it could actually do more harm than good by emitting potentially harmful amounts of ozone. A class-action lawsuit was
eventually filed against Sharper Image, and in 2008 the company declared bankruptcy. But that hasn't stopped others from peddling
dubious air purifiers. Last year we tested the Andrea, a fan-equipped purifier that supposedly harnesses the filtering power
of a houseplant (not included in the $200 price) to "create clean air for your family." But our tests found that it was ineffective
at removing common contaminants such as dust, pollen, and smoke. The LightAir IonFlow 50F, which costs $280, was also ineffective.
