Midea MDUDMB-50AEN8-BB0F dehumidifier: specs and cost to run

Our read

Who it suits

On the ENERGY STAR table, the MDUDMB-50AEN8-BB0F suits every space, wet ones over 2,000 sq ft included. Its running cost is close to the median, so drainage, noise, and price matter more.

Running cost

Its power bill is close to the norm

A portable lasts 11 years on average, by the DOE’s count. In that time, this model costs $10 less to run in the United States than the median 45–50 pint model. The thriftiest 45–50 pint model, the Aeocky LEO PRO-RCS50(Y)-N4-3(B)-25, would save $155 over those years.

The EPA doesn’t list the MDUDMB-50AEN8-BB0F as connected. Of the 156 certified 45–50 pint models, 14 are. In a crawl space you rarely open, a connected one saves the trip.

Ask before you buy

Ask for the pump lift and the lowest working temperature

Our sources don’t say whether the MDUDMB-50AEN8-BB0F has a pump, or how cold it can run. With no drain lower than the unit, the pump lift must reach your sink. Under 65°F, ENERGY STAR says the coils can frost.

From the data

Where it stands

Its 515 kWh a year is 5 kWh less than the median for its size.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Tied for 51st of 156 certified 45–50 pint portables for low energy use.
Its efficiency, 2.08 liters per kWh, is 30% above the federal minimum for its capacity class.The DOE sets 1.60 L/kWh for portables rated over 25 and up to 50 pints a day. Every unit made since June 13, 2019, must meet it.
The largest portable certified under the Midea name. Next down is the MDUDP-40AEN8-BB0, at 42 pints.That one uses 85 kWh a year less.
On the market since June 2025, newer than 13% of the 45–50 pint models on the list.
Not on the EPA’s Most Efficient list, which names 8 of the 45–50 pint models.
The company that files it also files the Pelonis models with the EPA.
The nearest size from another brand is the AUX ADT50V1, rated 50 pints and 504 kWh a year.In the United States, this one costs $2 a year more to run.

in the United States

A day of nonstop drying means 49.67 pints of water, about 6.2 gallons, for some 11.3 kWh. At the average home electricity price in the United States, the MDUDMB-50AEN8-BB0F costs $2.07 to run that day.

The EPA’s yearly estimate, 515 kWh, adds up to about 46 days like that. Each extra day at full output costs another $2.07.

Those 49.67 pints come from a DOE test at 65°F and 60% humidity. Cooler air at that humidity gives up less water, so expect fewer pints in a cold basement.

Every day at full output leaves 6.2 gallons to get rid of. Check how the MDUDMB-50AEN8-BB0F drains, since our sources don’t say.
