Total of 15 Sources
For an explanation of how we rank reviews, see our ratings criteria page.
by Editors of ConsumerReports.org
Our AssessmentConsumerReports.org conducts the most unbiased scientific tests of air purifiers. Editors test 32 air purifiers, ranking them from best to worst and identifying recommended models. Testers rate each model for dust, pollen and smoke removal (testing room filters on both low and high speeds) and noise at low and high speeds. Editors also estimate the annual cost of ownership for each model, based on energy and filter costs. Six air purifiers earn recommendations.
by Editors of AllergyBuyersClub.com
Our AssessmentAllergyBuyersClub.com is a retail website specializing in products that make life easier for allergy sufferers. Editors perform particle-removal testing in an unsealed office environment, and subjective criteria such as mechanical efficiency, noise level, ease of use, cost of ownership, filter access and customer feedback are factored into the ratings. Air purifiers are available in a variety of categories, from pet air purifiers to whole-house air purifiers. Models from IQAir are consistent winners across several categories.
Furnace Filters and Air Conditioning Filters
by Editors of AllergyBuyersClub.com
Our AssessmentRetailer AllergyBuyersClub.com also reviews furnace filters.

Disposable Filtrete filters -- which get the highest ratings elsewhere -- earn middling scores, while editors award EnviroSept Electronic and AC Furnace Filters with a perfect 5-star rating.

Best Product: IQAir HealthPro Plus
by Gregory Han
Our AssessmentEditor Gregory Han tests the IQAir HealthPro Plus in his Los Angeles apartment alongside less expensive purifiers from Holmes and Honeywell. He measures particulates using a $2,000 laser gauge, also on loan from the IQAir company. The IQAir purifier drastically reduces particulates, far beyond the capabilities of the cheaper units. The review is detailed and easy to read.

Our AssessmentPrevention magazine editor Amanda MacMillan says ionic and other ozone-generating air purifiers can be harmful to health and that desktop air purifiers of any type are too small to make much difference.
