Midea MDA50C4AWWCM dehumidifier: specs and cost to run

Our read

Who it suits

At 50 pints a day, the MDA50C4AWWCM fits every space in the ENERGY STAR table, wet ones over 2,000 sq ft included. Its yearly energy use sits near the median, so weigh drainage, noise, and price.

Running cost

A middle-of-the-pack power bill

Next to the median 45–50 pint model, this one costs $16 less 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 $149 over those years.

Wi-Fi app

You’ll check it in person

Like 141 other 45–50 pint models out of 156, the MDA50C4AWWCM 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 MDA50C4AWWCM 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

Its 512 kWh a year is 8 kWh less than the median for its size.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Of the 156 certified 45–50 pint portables, 42 use less energy, and 7 use exactly as much.
At 2.01 liters per kWh, it clears the federal minimum for its class by 26%.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.
Midea’s next size down is the MDUDP-40AEN8-BB0, rated 42 pints.That one uses 82 kWh a year less.
Sold since December 2025. Among 45–50 pint models, 100 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.
Another brand near this size: the Insignia NS-DH50WH7, at 50 pints and 512 kWh a year.Both cost the same to run in the United States.

in the United States

A day of nonstop drying means 49.95 pints of water, about 6.2 gallons, for some 11.8 kWh. At the average home electricity price in the United States, the MDA50C4AWWCM costs $2.15 to run that day.

The EPA’s yearly estimate, 512 kWh, adds up to about 44 days like that. Each extra day at full output costs another $2.15.

Those 49.95 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 MDA50C4AWWCM drains, since our sources don’t say.
