  • ENERGY STAR Most Efficient 2023
    Room Air Cleaners
    THE YEAR'S BEST OF ENERGY STAR FOR EFFICIENCY & INNOVATION

    Products that make the ENERGY STAR Most Efficient list for 2023 deliver cutting edge energy efficiency along with the latest in technological innovation. They represent the year’s very best for energy savings and environmental protection.
Clean Air Delivery Rate (CADR) is a measure of the amount of contaminant-free air delivered by the room air cleaner. The ENERGY STAR specification requires that manufacturers measure CADR according to AHAM/ANSI AC-1-2002, a test procedure developed by the Association of Home Appliance Manufacturers (AHAM), and recognized by the American National Standards Institute (ANSI). For more information about CADR please visit : www.cadr.org

When considering the purchase of an ENERGY STAR qualified room air cleaner, the comparison should not solely be based on CADR. The CADR of a specific air cleaner model is affected by a number of factors included the size of the model; larger units often have higher CADRs. For more information on the appropriate sized room air cleaner for your application please refer to individual manufacturers' web sites or ask your retailer.
