How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, NPL***-06C/X1E. 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. Both brands file NPL***-06C/X1E itself as their model number, so the number alone doesn't say which of them builds it.

Brands may still differ in color, controls, accessories, warranty and support. Full record and every model number: NEPO NPL***-06C/X1E.

How much does the NPL***-06C/X1E cost to run?

6,000 BTU/h SACC divided by a CEER of 6.6 is about 909 W while cooling. That's about 17¢ an hour, or $39.62 for 30 days at 8 hours 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 NPL***-06C/X1E, and is it the same under every brand?

Who makes the NINGPU NPL***-06C/X1E?
DOE's records don't say. The NINGPU NPL***-06C/X1E is filed under basic model NPL***-06C/X1E along with the NEPO NPL***-06C/X1E. Both brands file that same number as their model, and DOE's database has no manufacturer field.
Is the NINGPU NPL***-06C/X1E the same as the NEPO NPL***-06C/X1E?
Yes, by DOE's records. Both are filed under basic model NPL***-06C/X1E and list the same certified figures: 6,000 BTU/h SACC, CEER 6.6 and single hose.
Which brand of NPL***-06C/X1E is cheapest to run?
They tie: every brand files 6,000 BTU/h SACC, CEER 6.6 and single hose, so each costs about 17¢ an hour to run while cooling.
