From Consumer Reports: Quote:
Most people buy air purifiers to ease asthma or allergies. But despite product claims, there's little definitive medical evidence that air purifiers help relieve respiratory symptoms. Some may pose a threat even to healthy users.
....
Air purifiers that draw air through fabric filters are among those that do the best job of removing dust and smoke from the air without producing any ozone. Top-rated models such as the Whirlpool Whispure, $230, performed better at their lowest, quietest speeds than many others did at their higher, noisier settings. But simple steps such as those mentioned in Improving your air quality could improve air quality enough so that you don't need a purifier.
| And their quick recommendations: Quote:
Best room air purifiers:
Whirlpool Whispure AP45030S $230
Kenmore Progressive 83202 $270
Both combine fine performance with quieter operation, especially when set on low. The Hunter Permalife 30547 costs a bit less in annual costs but was noisier when run on high. Though the Friedrich C-90B and Kenmore (Sears) K6 85264 were better at dust removal on their high settings, they emitted moderate amounts of ozone in our tests, so we don't suggest you buy them.
