How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, K250F-C. 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. COOLTURE files K250F-C itself as one of its model numbers. The other 8 brands file under it with their own numbers.

Brands may still differ in color, controls, accessories, warranty and support. Full record and every model number: COOLTURE K250F-C.

How much does the K250F-C cost to run?

DOE's record lists 183 kWh a year, the annual energy figure from DOE's test. That's about $33.23 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 K250F-C, and is it the same under every brand?

Who makes the VOOPNU DH-JH023?
The VOOPNU DH-JH023 is filed with DOE under basic model K250F-C, which is COOLTURE's own model number. That makes COOLTURE the filer of record, though DOE's database has no manufacturer field to say who builds it.
Is the VOOPNU DH-JH023 the same as the COOLTURE K250F-C?
Yes, by DOE's records. Both are filed under basic model K250F-C and list the same certified figures: smoke CADR 121 cfm, PM2.5 CADR 127 cfm and a 188 sq ft room size.
Which brand of K250F-C is cheapest to run?
They tie: every brand files smoke CADR 121 cfm, PM2.5 CADR 127 cfm and a 188 sq ft room size, so each costs about $33.23 a year to run.
