How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, XT-C05. 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. All 3 brands file XT-C05 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: HEAPETS XT-C05.

How much does the XT-C05 cost to run?

DOE's record lists 347 kWh a year, the annual energy figure from DOE's test. That's about $63.02 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 XT-C05, and is it the same under every brand?

Who makes the SUMASHI P339?
DOE's records don't say. The SUMASHI P339 is filed under basic model XT-C05 along with 2 other brands. All of them file that same number as their model, and DOE's database has no manufacturer field.
Is the SUMASHI P339 the same as the HEAPETS P339?
Yes, by DOE's records. Both are filed under basic model XT-C05 and list the same certified figures: smoke CADR 193 cfm, PM2.5 CADR 205 cfm and a 299 sq ft room size.
Which brand of XT-C05 is cheapest to run?
They tie: every brand files smoke CADR 193 cfm, PM2.5 CADR 205 cfm and a 299 sq ft room size, so each costs about $63.02 a year to run.
