How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, YDY-32A. 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 YDY-32A 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: Fehom YDY-32A.

How much does the YDY-32A cost to run?

12.48 pints/day at an IEF of 1.89 L/kWh takes 3.12 kWh a day running nonstop at DOE's test conditions: about 57¢ a day, or $17.02 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.

Who makes the YDY-32A, and is it the same under every brand?

Who makes the KESNOS 1?
DOE's records don't say. The KESNOS 1 is filed under basic model YDY-32A along with 3 other brands. No brand files YDY-32A itself as a model number, and DOE's database has no manufacturer field.
Is the KESNOS 1 the same as the Fehom 1?
Yes, by DOE's records. Both are filed under basic model YDY-32A and list the same certified figures: 12.48 pints/day and IEF 1.89.
Which brand of YDY-32A is cheapest to run?
They tie: every brand files 12.48 pints/day and IEF 1.89, so each costs about 57¢ a day to run nonstop at DOE's test conditions.
