The filings

DOE lists one individual model number, PD30MA-20, under basic model PD30MA-20, filed under 2 brand names. Every filing lists the same figures: 18.5 pints/day and IEF 1.7.

How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, PD30MA-20. 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 PD30MA-20 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: KNKA PD30MA-20.

How much does the PD30MA-20 cost to run?

18.5 pints/day at an IEF of 1.7 L/kWh takes 5.15 kWh a day running nonstop at DOE's test conditions: about 94¢ a day, or $28.05 for 30 days. Real use cycles on and off with the humidity, so that's the upper figure for a day of nonstop running.

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 253 portable dehumidifiers up to 25 pints/day

Not counting 1 flagged filing far outside the class.

Who makes the PD30MA-20, and is it the same under every brand?

Who makes the KNKA PRO PD30MA-20?

DOE's records don't say. The KNKA PRO PD30MA-20 is filed under basic model PD30MA-20 along with the KNKA PD30MA-20. Both brands file that same number as their model, and DOE's database has no manufacturer field.

Is the KNKA PRO PD30MA-20 the same as the KNKA PD30MA-20?

Yes, by DOE's records. Both are filed under basic model PD30MA-20 and list the same certified figures: 18.5 pints/day and IEF 1.7.

Which brand of PD30MA-20 is cheapest to run?

They tie: every brand files 18.5 pints/day and IEF 1.7, so each costs about 94¢ a day to run nonstop at DOE's test conditions.
