Midea MAD22S1AWWT dehumidifier: specs and cost to run

Our read

Who it suits

On the ENERGY STAR table, the MAD22S1AWWT suits a damp space under 2,000 sq ft. It’s too small for a very damp or wet one. Pelonis lists two models with the same EPA figures, so compare prices.

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 $16 less to run in the United States than the median 19–28 pint model. The thriftiest 19–28 pint model, the Knka PD30MA-20, would save $93 over those years.

Same EPA figures as the Pelonis PAD22C1DWT

The company that files it with the EPA lists the Pelonis PAD22C1DWT and PAD22C1DWTS with the same capacity, energy use, and efficiency. Compare their prices and warranties before you choose.

Ask before you buy

Ask for a noise figure

Our sources publish no noise level for the MAD22S1AWWT. If it runs where you sleep or work, ask for a figure in dB(A), with the distance it was measured from.

At 276 kWh a year, it sits 8 kWh below the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
No Wi-Fi app.Not listed as connected.
Among the 155 certified 19–28 pint portables, 23 use less energy.
The federal floor for its class is 1.30 liters per kWh. It reaches 1.70, or 31% more.That floor covers portables rated 25 pints a day or less, for units made since June 13, 2019.
Midea also makes it smaller, the MAD20S1QWT at 20 pints, and bigger, the MDUDA-25AEN8-BB0F at 27 pints.The bigger one uses 7 kWh a year more.

in the United States

A day of nonstop drying means 22.27 pints of water, about 2.8 gallons, for some 6.2 kWh. At the average home electricity price in the United States, the MAD22S1AWWT costs $1.13 to run that day.

The EPA’s yearly estimate, 276 kWh, adds up to about 45 days like that. Each extra day at full output costs another $1.13.

Those 22.27 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 2.8 gallons to get rid of. Check how the MAD22S1AWWT drains, since our sources don’t say.
