How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, DFH1-50EPD(04). 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(04) 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: waykar CTH150B.

How much does the DFH1-50EPD(04) cost to run?

49.43 pints/day at an IEF of 2.2 L/kWh takes 10.63 kWh a day running nonstop at DOE's test conditions: about $1.93 a day, or $57.92 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 DFH1-50EPD(04), and is it the same under every brand?

Who makes the Megalight PD-HPC750-WT?
DOE's records don't say. The Megalight PD-HPC750-WT is filed under basic model DFH1-50EPD(04) along with the waykar CTH150B. Neither brand files DFH1-50EPD(04) itself as a model number, and DOE's database has no manufacturer field.
Is the Megalight PD-HPC750-WT the same as the waykar CTH150B?
Yes, by DOE's records. Both are filed under basic model DFH1-50EPD(04) and list the same certified figures: 49.43 pints/day and IEF 2.2.
Which brand of DFH1-50EPD(04) is cheapest to run?
They tie: every brand files 49.43 pints/day and IEF 2.2, so each costs about $1.93 a day to run nonstop at DOE's test conditions.
