The filings

DOE lists one individual model number, NPN-08H/X1E, under basic model NPN-08H/X1E, filed under 2 brand names. Every filing lists the same figures: 8,000 BTU/h SACC, CEER 7.2 and single hose.

Each brand's DOE filing under basic model NPN-08H/X1E, DOE data as of 2026-11-03. Identical columns are the evidence.

How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, NPN-08H/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 NPN-08H/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 NPN-08H/X1E.

How much does the NPN-08H/X1E cost to run?

8,000 BTU/h SACC divided by a CEER of 7.2 is about 1,111 W while cooling. That's about 20¢ an hour, or $48.43 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 NPN-08H/X1E, and is it the same under every brand?

Who makes the NINGPU NPN-08H/X1E?
DOE's records don't say. The NINGPU NPN-08H/X1E is filed under basic model NPN-08H/X1E along with the NEPO NPN-08H/X1E. Both brands file that same number as their model, and DOE's database has no manufacturer field.
Is the NINGPU NPN-08H/X1E the same as the NEPO NPN-08H/X1E?
Yes, by DOE's records. Both are filed under basic model NPN-08H/X1E and list the same certified figures: 8,000 BTU/h SACC, CEER 7.2 and single hose.
Which brand of NPN-08H/X1E is cheapest to run?
They tie: every brand files 8,000 BTU/h SACC, CEER 7.2 and single hose, so each costs about 20¢ an hour to run while cooling.
