Running cost
Cheaper to run than most 29–44 pint models
It uses 39 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 $79 saved in the United States.

Who it suits
Rated 32 pints a day, the DR-HDH004S 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.

Wi-Fi app
You can check it from your phone
Of the 87 certified 29–44 pint models, only 8 have a Wi-Fi app, and the DR-HDH004S is one. In a basement or crawl space you rarely visit, you read the humidity without going down.
Crawl space dehumidifier guideAsk before you buy
Ask for the pump lift and the lowest working temperature
Neither figure is in our sources for the DR-HDH004S. 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.
Plan the drainFrom the data
Where it stands
- At 335 kWh a year, it sits 39 kWh below the middle of its class.
- Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
- Among the 87 certified 29–44 pint portables, 2 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 Dreo name. Next down is the DR-HDH003S, at 22 pints.That one uses 64 kWh a year less.
- On the market since March 2026, newer than 79% 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 Aeocky LEO-RCS32(Y)-N4-3(B) is the closest size from another brand, rated 32 pints and 336 kWh a year.In the United States, this one costs $1 a year less to run.

in the United States
Run for a whole day at its rating, the DR-HDH004S removes 31.71 pints, about 4 gallons, on roughly 7.5 kWh. In the United States, that’s $1.37.
Divide the EPA’s 335 kWh a year by one full day’s use, and you get roughly 45 days. Past that, each day at full output adds $1.37 to the bill.
The DOE test behind those 31.71 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the DR-HDH004S.
Without a hose or a pump, someone has to carry out 4 gallons a day. Our sources don’t say whether the DR-HDH004S has a bucket, or how much it holds.
