How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, DH-JH11W. 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. No brand files DH-JH11W itself as a model number. It's the code DOE uses to tie their filings together.

Brands may still differ in color, controls, accessories, warranty and support. Full record and every model number: PISCES HEALTHCARE 2AP2011WTR.

How much does the DH-JH11W cost to run?

DOE's record lists 238 kWh a year, the annual energy figure from DOE's test. That's about $43.22 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 DH-JH11W, and is it the same under every brand?

Who makes the True 42 2AP2011WTR?
DOE's records don't say. The True 42 2AP2011WTR is filed under basic model DH-JH11W along with the PISCES HEALTHCARE 2AP2011WTR. Neither brand files DH-JH11W itself as a model number, and DOE's database has no manufacturer field.
Is the True 42 2AP2011WTR the same as the PISCES HEALTHCARE 2AP2011WTR?
Yes, by DOE's records. Both are filed under basic model DH-JH11W and list the same certified figures: smoke CADR 159 cfm, PM2.5 CADR 161 cfm and a 246 sq ft room size.
Which brand of DH-JH11W is cheapest to run?
They tie: every brand files smoke CADR 159 cfm, PM2.5 CADR 161 cfm and a 246 sq ft room size, so each costs about $43.22 a year to run.
