How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, KD3-W. 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 KD3-W 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: HASHONE KD3-W.

How much does the KD3-W cost to run?

DOE's record lists 188 kWh a year, the annual energy figure from DOE's test. That's about $34.14 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 KD3-W, and is it the same under every brand?

Who makes the TER AIR KD3?
DOE's records don't say. The TER AIR KD3 is filed under basic model KD3-W along with the HASHONE KD3. Both brands file that same number as their model, and DOE's database has no manufacturer field.
Is the TER AIR KD3 the same as the HASHONE KD3?
Yes, by DOE's records. Both are filed under basic model KD3-W and list the same certified figures: smoke CADR 103 cfm, PM2.5 CADR 107 cfm and a 160 sq ft room size.
Which brand of KD3-W is cheapest to run?
They tie: every brand files smoke CADR 103 cfm, PM2.5 CADR 107 cfm and a 160 sq ft room size, so each costs about $34.14 a year to run.
