Midea MAD50PS1AWT-S dehumidifier: specs and cost to run

Our read

Who it suits

On the ENERGY STAR table, the MAD50PS1AWT-S suits every space, wet ones over 2,000 sq ft included. Its yearly energy use sits near the median, so weigh drainage, noise, and price.

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

Running cost

Its power bill is close to the norm

It uses 520 kWh a year, the median for 45–50 pint models. The thriftiest of its size, the Aeocky LEO PRO-RCS50(Y)-N4-3(B)-25, would save $165 in the United States over 11 years. That’s the DOE’s average life for a portable.

Wi-Fi app

You’ll check it in person

Like 141 other 45–50 pint models out of 156, the MAD50PS1AWT-S 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

Our sources don’t say whether the MAD50PS1AWT-S 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

Uses 520 kWh a year, the median of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Among the 156 certified 45–50 pint portables, 77 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 90 kWh a year less.
Sold since April 2026. Among 45–50 pint models, 132 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 Insignia NS-DH50WH7 is the closest size from another brand, rated 50 pints and 512 kWh a year.In the United States, this one costs $1 a year more to run.

in the United States

Run for a whole day at its rating, the MAD50PS1AWT-S removes 49.95 pints, about 6.2 gallons, on roughly 11.8 kWh. In the United States, that’s $2.15.

Divide the EPA’s 520 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 49.95 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the MAD50PS1AWT-S.

Without a hose or a pump, someone has to carry out 6.2 gallons a day. Our sources don’t say whether the MAD50PS1AWT-S has a bucket, or how much it holds.
