How we know it's one unit
Every brand here filed its model numbers under the same DOE basic model, HAP611WF. DOE's definition of a basic model (10 CFR 430.2) covers "all units of a given type of covered product (or class thereof) manufactured by one manufacturer" with "the same primary energy source" and nearly identical "electrical, physical, and functional (or hydraulic) characteristics that affect energy consumption, energy efficiency, water consumption, or water efficiency." So one set of DOE figures covers every name on the list. BAREN files HAP611WF itself as one of its model numbers. The other brand files under it with its own numbers.
Brands may still differ in color, controls, accessories, warranty and support. Full record and every model number: BAREN HAP611WF.
How much does the HAP611WF cost to run?
DOE's record lists 247 kWh a year, the annual energy figure from DOE's test. That's about $44.86 a year.
At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.
