How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, DH-JHK02. 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 DH-JHK02 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: PISCES HEALTHCARE 250MK026TR.

How much does the DH-JHK02 cost to run?

DOE's record lists 41 kWh a year, the annual energy figure from DOE's test. That's about $7.45 a year.

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 DH-JHK02, and is it the same under every brand?

Who makes the True 42 250MK026TR?
DOE's records don't say. The True 42 250MK026TR is filed under basic model DH-JHK02 along with the PISCES HEALTHCARE 250MK026TR. Neither brand files DH-JHK02 itself as a model number, and DOE's database has no manufacturer field.
Is the True 42 250MK026TR the same as the PISCES HEALTHCARE 250MK026TR?
Yes, by DOE's records. Both are filed under basic model DH-JHK02 and list the same certified figures: smoke CADR 25 cfm, PM2.5 CADR 26 cfm and a 39 sq ft room size.
Which brand of DH-JHK02 is cheapest to run?
They tie: every brand files smoke CADR 25 cfm, PM2.5 CADR 26 cfm and a 39 sq ft room size, so each costs about $7.45 a year to run.
