Running cost
Cheaper to run than most 29–44 pint models
It uses 31 kWh a year less than the median 29–44 pint model. Over 11 years, the DOE’s average life for a portable, that’s about $62 saved in the United States.

Who it suits
Rated 32 pints a day, the WHAD321AW is sized for a wet space under 2,000 sq ft, or a damp one over. It’s one of the cheaper models of its size to run.

The EPA doesn’t list the WHAD321AW 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
Neither figure is in our sources for the WHAD321AW. 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.

Where it stands
- Uses 343 kWh a year, 31 kWh under the median of its class.
- Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
- Of the 87 certified 29–44 pint portables, 16 use less energy, and 11 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 Whirlpool lineup, the next size down is the WHAD251AW, at 25 pints. The next size up is the WHHD501AW, at 50 pints.The bigger one uses 187 kWh a year more.
- On the market since September 2025, newer than 40% 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 Amana and Keystone models with the EPA.
- Another brand near this size: the hOmeLabs HME0089, at 32 pints and 343 kWh a year.Both cost the same to run in the United States.

in the United States
In 24 hours at full output, the WHAD321AW pulls about 4.1 gallons of water from the air and uses about 7.6 kWh. That day costs $1.40 in the United States.
About 45 such days make up the EPA’s yearly estimate of 343 kWh. If yours runs at full output more often, every extra day adds $1.40.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the WHAD321AW pulls out less than 32.46 pints a day.
Those 4.1 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 WHAD321AW has.
