Controversial Rankings
Air cleaner reviews from Consumer Reports date back to the early 1990's, but it is their more recent air purifiers articles that have stirred controversy and invited criticism. In 2003 and again in early 2005, CR took aim at a group of ionizing air cleaners which included best seller Sharper Image Ionic Breeze and runner-up Oreck. In their traditional groundbreaking style, the magazine gave considerable space to the ozone issue, and exposed questionable practices of two allergy foundations granting "seals of approval" to Breeze and Oreck air cleaners.
By October, 2005, a series of ill-advised legal attacks had left Ionic Breeze "stuck to the Tar Baby", as a Federal Court sided with CR after reviewing technical merits of both claims. Oreck, with no shareholder groups to clamor for action, wisely ignored the bait.
In the October 2005 issue, an article titled "Air Cleaners: Some Do Little Cleaning" ranked 30 air purifiers and renewed criticism of testing methods.
Few qualified air purifiers reviewers would take issue with ranking the Oreck xl, Sharper Image Ionic Breeze, Ionic Pro, and Surround Air xj-2000 at the bottom.
But credulity in the air purifier community was strained when Consumer Reports ranked purifier industry quality leaders IQ-Air and Austin Air poorly. IQ-Air purifiers are ranked number 19, just below the 112 CADR, $70 at Wal-Mart, 3-stars at Amazon.com, Holmes Harmony HAP-422-U!
And as pigs grew wings, thousands of "consumers" took these rankings as gospel, racing to buy the top pick, the powerful, but ozone emitting, Friedrich C90A electrostatic precipitator air purifiers.
Critics howled "foul."
The controversy centers around selection methods, testing procedures, and reporting style.
