How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, AP4416-UL. 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 AP4416-UL 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: COWSAR AP4416-UL.

How much does the AP4416-UL cost to run?

DOE's record lists 255 kWh a year, the annual energy figure from DOE's test. That's about $46.31 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 AP4416-UL, and is it the same under every brand?

Who makes the KISSAIR AP4416-UL?
DOE's records don't say. The KISSAIR AP4416-UL is filed under basic model AP4416-UL along with the COWSAR AP4416-UL. Both brands file that same number as their model, and DOE's database has no manufacturer field.
Is the KISSAIR AP4416-UL the same as the COWSAR AP4416-UL?
Yes, by DOE's records. Both are filed under basic model AP4416-UL and list the same certified figures: smoke CADR 297 cfm, PM2.5 CADR 303 cfm and a 460 sq ft room size.
Which brand of AP4416-UL is cheapest to run?
They tie: every brand files smoke CADR 297 cfm, PM2.5 CADR 303 cfm and a 460 sq ft room size, so each costs about $46.31 a year to run.
