How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, PR1 E220. 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 3 brands file PR1 E220 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: BAREN PR1 E220.

How much does the PR1 E220 cost to run?

DOE's record lists 190 kWh a year, the annual energy figure from DOE's test. That's about $34.50 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 PR1 E220, and is it the same under every brand?

Who makes the KOIOS PR1 E220?
DOE's records don't say. The KOIOS PR1 E220 is filed under basic model PR1 E220 along with 2 other brands. All of them file that same number as their model, and DOE's database has no manufacturer field.
Is the KOIOS PR1 E220 the same as the BAREN PR1 E220?
Yes, by DOE's records. Both are filed under basic model PR1 E220 and list the same certified figures: smoke CADR 121 cfm, PM2.5 CADR 127 cfm and a 188 sq ft room size.
Which brand of PR1 E220 is cheapest to run?
They tie: every brand files smoke CADR 121 cfm, PM2.5 CADR 127 cfm and a 188 sq ft room size, so each costs about $34.50 a year to run.
