Air Purifiers
by Editors of ConsumerReports.org
Our AssessmentConsumerReports.org conducts hands-on tests of room air purifiers and furnace filters. Each is ranked from best to worst and some are recommended models; a few also get a Best Buy nod. 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.
The AHAM Verification Program for Portable Electric Room Air Cleaners
by Editors of the Association of Home Appliance Manufacturers
Our AssessmentThe Association of Home Appliance Manufacturers (AHAM) uses an outside lab to verify clean air delivery rates (CADRs) quoted by manufacturers for dust, tobacco smoke and pollen. Manufacturer participation is voluntary, and tested samples are taken randomly from factories, warehouses and dealer showrooms. Air purifiers that are certified to meet Energy Star standards and UL safety standards for ozone emissions are also identified, but that certification is not independently tested.
