How we know it's one unit
Every brand here filed its model numbers under the same DOE basic model, TDW80B. 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 TDW80B 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 TDW80E.
How much does the TDW80B cost to run?
24.66 pints/day at an IEF of 1.85 L/kWh takes 6.31 kWh a day running nonstop at DOE's test conditions: about $1.15 a day, or $34.36 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 TDW80B, and is it the same under every brand?
- Who makes the waykar TDW80E?
- DOE's records don't say. The waykar TDW80E is filed under basic model TDW80B along with 3 other brands. No brand files TDW80B itself as a model number, and DOE's database has no manufacturer field.
- Is the waykar TDW80E the same as the Fehom TDW80E?
- Yes, by DOE's records. Both are filed under basic model TDW80B and list the same certified figures: 24.66 pints/day and IEF 1.85.
- Which brand of TDW80B is cheapest to run?
- They tie: every brand files 24.66 pints/day and IEF 1.85, so each costs about $1.15 a day to run nonstop at DOE's test conditions.
