Our read
Who it suits
Rated 49 pints a day, the AMND501PBW is sized for a wet space under 2,000 sq ft, or a very 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
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 doesn’t list the AMND501PBW as connected. Of the 156 certified 45–50 pint models, 14 are. In a crawl space you rarely open, a connected one saves the trip.
Ask for the pump lift and the lowest working temperature
Neither figure is in our sources for the AMND501PBW. 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.
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.
Sold since August 2026. Among 45–50 pint models, 147 of 156 came out earlier.Certified in August 2026, one of the 97 models certified in the last six months.
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 Keystone and Whirlpool models with the EPA.
The Waykar CTH150B is the closest size from another brand, rated 49 pints and 471 kWh a year.In the United States, this one costs $9 a year more to run.

In 24 hours at full output, the AMND501PBW pulls about 6.2 gallons of water from the air and uses about 11.6 kWh. That day costs $2.13 in the United States.
About 45 such days make up the EPA’s yearly estimate of 520 kWh. If yours runs at full output more often, every extra day adds $2.13.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the AMND501PBW pulls out less than 49.43 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 AMND501PBW has.
