Filtering the claims.(AIR PURIFIERS)
Most people buy air purifiers to ease asthma or allergies. But despite product claims, there's little definitive medical evidence that purifiers help relieve respiratory symptoms. Some may pose a threat even to healthy users.
Electrostatic precipitators are the most heavily promoted purifiers, accounting for about half of the models sold. Oreck and Sharper Image versions are best sellers, despite their lackluster air-cleaning performance in our tests. Electrostatic precipitators trap particles by applying an electrical charge to them as they pass through the unit and depositing them on plates or filters. The process creates some ozone as a byproduct.
