Midea MDUDP-50AEN8-BB0 dehumidifier: specs and cost to run

Our read

Who it suits

At 50 pints a day, the MDUDP-50AEN8-BB0 fits every space in the ENERGY STAR table, wet ones over 2,000 sq ft included. Pelonis lists a model with the same EPA figures, so compare prices.

Running cost

A middle-of-the-pack power bill

Next to the median 45–50 pint model, this one costs $10 more to run in the United States over 11 years. That’s how long the DOE expects a portable to last. The thriftiest 45–50 pint model, the Aeocky LEO PRO-RCS50(Y)-N4-3(B)-25, would save $175 over those years.

Same figures, other brand

A Pelonis model with the same EPA figures

The company that files it with the EPA lists the Pelonis PAD50P1ABLS with the same capacity, energy use, and efficiency. Check both prices, and both warranties, before you buy.

Wi-Fi app

You’ll check it in person

Like 141 other 45–50 pint models out of 156, the MDUDP-50AEN8-BB0 has no Wi-Fi app on the EPA list. In a basement you rarely visit, plan to check it in person.

Ask before you buy

Ask about the pump, and about the cold

Pump and cold are the two blanks for the MDUDP-50AEN8-BB0 in our sources. A pump matters when water can’t run down to a floor drain. Cold matters because below 65°F, ENERGY STAR says frost can form on the coils.

From the data

Where it stands

At 525 kWh a year, it sits 5 kWh above the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Among the 156 certified 45–50 pint portables, 102 use less energy.
The federal floor for its class is 1.60 liters per kWh. It reaches 2.01, or 26% more.That floor covers portables rated over 25 and up to 50 pints a day, for units made since June 13, 2019.
Midea’s next size down is the MDUDP-40AEN8-BB0, rated 42 pints.That one uses 95 kWh a year less.
Sold since June 2025. Among 45–50 pint models, 10 of 156 came out earlier.
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 Amazon Basics B0GR2TN8YX is the closest size from another brand, rated 50 pints and 525 kWh a year.Both cost the same to run in the United States.

in the United States

In 24 hours at full output, the MDUDP-50AEN8-BB0 pulls about 6.2 gallons of water from the air and uses about 11.7 kWh. That day costs $2.14 in the United States.

About 45 such days make up the EPA’s yearly estimate of 525 kWh. If yours runs at full output more often, every extra day adds $2.14.

Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the MDUDP-50AEN8-BB0 pulls out less than 49.74 pints a day.

Those 6.2 gallons need a way out: a hose to a drain, a pump, or a bucket you empty. Our sources don’t say which ones the MDUDP-50AEN8-BB0 has.
