How we know it's one unit
Every brand here filed its model numbers under the same DOE basic model, MR2588. 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 4 brands file MR2588 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: CHIVALZ MR2588.
How much does the MR2588 cost to run?
DOE's record lists 34 kWh a year, the annual energy figure from DOE's test. That's about $6.17 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 MR2588, and is it the same under every brand?
- Who makes the Evalit ET2588?
- DOE's records don't say. The Evalit ET2588 is filed under basic model MR2588 along with 3 other brands. All of them file that same number as their model, and DOE's database has no manufacturer field.
- Is the Evalit ET2588 the same as the CHIVALZ ET2588?
- Yes, by DOE's records. Both are filed under basic model MR2588 and list the same certified figures: smoke CADR 19 cfm, PM2.5 CADR 22 cfm and a 29 sq ft room size.
- Which brand of MR2588 is cheapest to run?
- They tie: every brand files smoke CADR 19 cfm, PM2.5 CADR 22 cfm and a 29 sq ft room size, so each costs about $6.17 a year to run.
