Our read
Who it suits
At 50 pints a day, the MAD50PS1BWT-C fits every space in the ENERGY STAR table, 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.

A middle-of-the-pack power bill
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.
The EPA lists the MAD50PS1BWT-C as connected, like 13 other 45–50 pint models out of 156. From your phone, you can check a crawl space or basement without going down.
Pump and cold are the two blanks for the MAD50PS1BWT-C in our sources. A pump matters when water can’t run down to a floor drain. Cold matters because below 65°F, ENERGY STAR says frost can form on the coils.
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.
The largest portable certified under the Midea name. Next down is the MDUDP-40AEN8-BB0, at 42 pints.That one uses 90 kWh a year less.
On the market since October 2025, newer than 40% of the 45–50 pint models on the list.
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 24 hours at full output, the MAD50PS1BWT-C pulls about 6.2 gallons of water from the air and uses about 11.8 kWh. That day costs $2.15 in the United States.
About 44 such days make up the EPA’s yearly estimate of 520 kWh. If yours runs at full output more often, every extra day adds $2.15.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the MAD50PS1BWT-C pulls out less than 49.95 pints a day.
Those 6.2 gallons need a way out: a hose to a drain, a pump, or a bucket you empty. Our sources don’t say which ones the MAD50PS1BWT-C has.
