The filings

DOE lists 4 individual model numbers under basic model KJ450F-A1, filed under 6 brand names. Every filing lists the same figures: smoke CADR 219 cfm, PM2.5 CADR 226 cfm and a 339 sq ft room size.

How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, KJ450F-A1. 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. All 6 brands file KJ450F-A1 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: Aeitto KJ450F-A1.

How much does the KJ450F-A1 cost to run?

DOE's record lists 314 kWh a year, the annual energy figure from DOE's test. That's about $57.02 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.

Among 140 air purifiers, PM2.5 CADR 150+ cfm

Who makes the KJ450F-A1, and is it the same under every brand?

Who makes the ECOSELF HAP10?

DOE's records don't say. The ECOSELF HAP10 is filed under basic model KJ450F-A1 along with 5 other brands. All of them file that same number as their model, and DOE's database has no manufacturer field.

Is the ECOSELF HAP10 the same as the Aeitto HAP10?

Yes, by DOE's records. Both are filed under basic model KJ450F-A1 and list the same certified figures: smoke CADR 219 cfm, PM2.5 CADR 226 cfm and a 339 sq ft room size.

Which brand of KJ450F-A1 is cheapest to run?

They tie: every brand files smoke CADR 219 cfm, PM2.5 CADR 226 cfm and a 339 sq ft room size, so each costs about $57.02 a year to run.
