How we know it's one unit
Every brand here filed its model numbers under the same DOE basic model, APH2500P. 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 APH2500P 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: FMUKL APH2500P.
How much does the APH2500P cost to run?
DOE's record lists 137 kWh a year, the annual energy figure from DOE's test. That's about $24.88 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 APH2500P, and is it the same under every brand?
- Who makes the KNKA AP250P?
- DOE's records don't say. The KNKA AP250P is filed under basic model APH2500P along with the FMUKL AP250P. Both brands file that same number as their model, and DOE's database has no manufacturer field.
- Is the KNKA AP250P the same as the FMUKL AP250P?
- Yes, by DOE's records. Both are filed under basic model APH2500P and list the same certified figures: smoke CADR 119 cfm, PM2.5 CADR 121 cfm and a 184 sq ft room size.
- Which brand of APH2500P is cheapest to run?
- They tie: every brand files smoke CADR 119 cfm, PM2.5 CADR 121 cfm and a 184 sq ft room size, so each costs about $24.88 a year to run.
