How we know it's one unit
Every brand here filed its model numbers under the same DOE basic model, AP304. 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 AP304 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: AIRFIRE AP201.
How much does the AP304 cost to run?
DOE's record lists 258 kWh a year, the annual energy figure from DOE's test. That's about $46.85 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 AP304, and is it the same under every brand?
- Who makes the DAYETTE AP201?
- DOE's records don't say. The DAYETTE AP201 is filed under basic model AP304 along with 3 other brands. No brand files AP304 itself as a model number, and DOE's database has no manufacturer field.
- Is the DAYETTE AP201 the same as the AIRFIRE AP201?
- Yes, by DOE's records. Both are filed under basic model AP304 and list the same certified figures: smoke CADR 151 cfm, PM2.5 CADR 154 cfm and a 234 sq ft room size.
- Which brand of AP304 is cheapest to run?
- They tie: every brand files smoke CADR 151 cfm, PM2.5 CADR 154 cfm and a 234 sq ft room size, so each costs about $46.85 a year to run.
