How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, EAH-B1. 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 EAH-B1 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: EZDONE EAH-B1.

How much does the EAH-B1 cost to run?

DOE's record lists 81 kWh a year, the annual energy figure from DOE's test. That's about $14.71 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 EAH-B1, and is it the same under every brand?

Who makes the YADU EAH-B1?
DOE's records don't say. The YADU EAH-B1 is filed under basic model EAH-B1 along with the EZDONE EAH-B1. Both brands file that same number as their model, and DOE's database has no manufacturer field.
Is the YADU EAH-B1 the same as the EZDONE EAH-B1?
Yes, by DOE's records. Both are filed under basic model EAH-B1 and list the same certified figures: smoke CADR 44 cfm, PM2.5 CADR 47 cfm and a 68 sq ft room size.
Which brand of EAH-B1 is cheapest to run?
They tie: every brand files smoke CADR 44 cfm, PM2.5 CADR 47 cfm and a 68 sq ft room size, so each costs about $14.71 a year to run.
