How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, DFH1-50EPD. 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 DFH1-50EPD 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: Honeywell TPFIT50WK.

How much does the DFH1-50EPD cost to run?

49.66 pints/day at an IEF of 2.01 L/kWh takes 11.69 kWh a day running nonstop at DOE's test conditions: about $2.12 a day, or $63.69 for 30 days. Real use cycles on and off with the humidity, so that's the upper figure for a day of nonstop running. The filings differ, so the cost does too: lowest for 3 brands ($2.12 a day), highest for TCL ($2.14 a day).

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 DFH1-50EPD, and is it the same under every brand?

Who makes the waykar CTH150A?
DOE's records don't say. The waykar CTH150A is filed under basic model DFH1-50EPD along with 3 other brands. No brand files DFH1-50EPD itself as a model number, and DOE's database has no manufacturer field.
Is the waykar CTH150A the same as the Honeywell TPFIT50APWK?
Yes, by DOE's records. Both are filed under basic model DFH1-50EPD and list the same certified figures: 49.66 pints/day and IEF 2.01.
Which brand of DFH1-50EPD is cheapest to run?
On the filed figures, the 3 brands that file 49.66 pints/day and IEF 2.01, at about $2.12 a day. The highest is TCL at about $2.14 a day.
