Midea MAD35S1QWT-A dehumidifier: specs and cost to run

Our read

Who it suits

Rated 36 pints a day, the MAD35S1QWT-A is sized for a wet space under 2,000 sq ft, or a damp one over. 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 $8 more to run in the United States than the median 29–44 pint model. The thriftiest 29–44 pint model, the Deciuu LIBRA-RCS32(Y)-N4-3(B), would save $91 over those years.

The EPA doesn’t list the MAD35S1QWT-A as connected. Of the 87 certified 29–44 pint models, 8 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 MAD35S1QWT-A. 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

Its 378 kWh a year is 4 kWh more than the median for its size.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Of the 87 certified 29–44 pint portables, 51 use less energy, and 6 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.
In the Midea lineup, the next size down is the MDUDA-25AEN8-BB0F, at 27 pints. The next size up is the MAD35C1AWS-A, at 37 pints.The bigger one uses 10 kWh a year more.
On the market since October 2025, newer than 51% of the 29–44 pint models on the list.
Not on the EPA’s Most Efficient list, which names 1 of the 29–44 pint models.
The company that files it also files the Pelonis models with the EPA.
Another brand near this size: the Frigidaire FHDD3534Y1, at 36 pints and 379 kWh a year.Both cost the same to run in the United States.

in the United States

Run for a whole day at its rating, the MAD35S1QWT-A removes 35.82 pints, about 4.5 gallons, on roughly 8.4 kWh. In the United States, that’s $1.54.

Divide the EPA’s 378 kWh a year by one full day’s use, and you get roughly 45 days. Past that, each day at full output adds $1.54 to the bill.

The DOE test behind those 35.82 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the MAD35S1QWT-A.

Without a hose or a pump, someone has to carry out 4.5 gallons a day. Our sources don’t say whether the MAD35S1QWT-A has a bucket, or how much it holds.
