How efficient is the Multistar MDHP5079USW?

Multistar MDHP5079USW files IEF 2.01 L/kWh. The median among the 296 models in its DOE class (portable dehumidifiers, 25 to 50 pints/day) is 1.91, so it's above the median: higher than 161 of the 296.

A higher IEF means more water removed per kWh.

Who makes Multistar dehumidifiers?

DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.

Its one basic model isn't filed by any other brand as of 2026-11-03, and the model number isn't another company's. DOE's records tie it to Multistar alone.

How much does a Multistar dehumidifier cost to run?

Multistar MDHP5079USW certifies 49.48 pints/day (23.41 liters) at an IEF of 2.01 L/kWh. That takes 11.65 kWh a day running nonstop at DOE's test conditions: about $2.12 a day, or $63.46 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.

Questions about Multistar

Is Multistar a good dehumidifier brand?
Its one dehumidifier basic model, Multistar MDHP5079USW, certifies 49.48 pints/day under the 2019 DOE test, and its IEF of 2.01 is higher than 161 of the 296 in its DOE class (portable dehumidifiers, 25 to 50 pints/day). We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
Does Multistar make a 50 pint dehumidifier?
No current DOE record shows one as of 2026-11-03. Its one model, Multistar MDHP5079USW, certifies 49.48 pints/day under the 2019 DOE test. Boxes that quote the older 80°F test read higher for the same unit. How the 2019 test changed pint ratings.
