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

Our read

Who it suits

Rated 50 pints a day, the MDUDT-50AEN8-BB0F is sized for every space in the ENERGY STAR table, wet ones over 2,000 sq ft included. Its running cost is close to the median, so drainage, noise, and price matter more.

Capacity suggested for each case, read Oct 5, 2026. ENERGY STAR adds that it’s better to oversize than undersize.

Running cost

Running cost won’t decide it

The DOE puts a portable’s average life at 11 years. Over that time, this model costs $6 more 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 $171 over those years.

The EPA doesn’t list the MDUDT-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

Neither figure is in our sources for the MDUDT-50AEN8-BB0F. Without a floor drain below it, a pump has to lift the water to a sink. Basements run cool, and below 65°F, ENERGY STAR says frost can form on the coils.

From the data

Where it stands

At 523 kWh a year, it sits 3 kWh above the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Ranks 101st of 156 certified 45–50 pint portables for low energy use.
Its efficiency, 2.01 liters per kWh, is 26% 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.
Midea’s next size down is the MDUDP-40AEN8-BB0, rated 42 pints.That one uses 93 kWh a year less.
Sold since September 2026. Among 45–50 pint models, 154 of 156 came out earlier.Certified in September 2026, one of the 97 models certified in the last six months.
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 Insignia NS-DH50WH7, rated 50 pints and 512 kWh a year.In the United States, this one costs $2 a year more to run.

in the United States

Run for a whole day at its rating, the MDUDT-50AEN8-BB0F removes 49.96 pints, about 6.2 gallons, on roughly 11.8 kWh. In the United States, that’s $2.15.

Divide the EPA’s 523 kWh a year by one full day’s use, and you get roughly 44 days. Past that, each day at full output adds $2.15 to the bill.

The DOE test behind those 49.96 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the MDUDT-50AEN8-BB0F.

Without a hose or a pump, someone has to carry out 6.2 gallons a day. Our sources don’t say whether the MDUDT-50AEN8-BB0F has a bucket, or how much it holds.
