How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, OL35-D076DDN3B1/E. 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. No brand files OL35-D076DDN3B1/E itself as a model number. It's the code DOE uses to tie their filings together.

Brands may still differ in color, controls, accessories, warranty and support. Full record and every model number: Auseo D4280-WHITE.

How much does the OL35-D076DDN3B1/E cost to run?

35.85 pints/day at an IEF of 1.98 L/kWh takes 8.57 kWh a day running nonstop at DOE's test conditions: about $1.56 a day, or $46.67 for 30 days. Real use cycles on and off with the humidity, so that's the upper figure for a day of nonstop running.

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.
