Our read
Who it suits
On the ENERGY STAR table, the MAD35S1BWWT suits a wet space under 2,000 sq ft, or a damp one over. Pelonis lists a model with the same EPA figures, so compare prices.
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
A portable lasts 11 years on average, by the DOE’s count. In that time, this model costs $18 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 $101 over those years.
The company that files it with the EPA lists the Pelonis PAD35C1DWTS with the same capacity, energy use, and efficiency. Compare their prices and warranties before you choose.
Wi-Fi app
No app to watch it from upstairs
The EPA doesn’t list the MAD35S1BWWT 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 for the pump lift and the lowest working temperature
Our sources don’t say whether the MAD35S1BWWT 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.
Its 383 kWh a year is 9 kWh more than the median for its size.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Tied for 72nd of 87 certified 29–44 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.
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 5 kWh a year more.
On the market since October 2025, newer than 53% 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.
The nearest size from another brand is the BLACK+DECKER BDM36WCDA, rated 36 pints and 383 kWh a year.Both cost the same to run in the United States.

A day of nonstop drying means 36.39 pints of water, about 4.5 gallons, for some 8.6 kWh. At the average home electricity price in the United States, the MAD35S1BWWT costs $1.57 to run that day.
The EPA’s yearly estimate, 383 kWh, adds up to about 45 days like that. Each extra day at full output costs another $1.57.
Those 36.39 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 4.5 gallons to get rid of. Check how the MAD35S1BWWT drains, since our sources don’t say.
