Our read
Who it suits
At 22 pints a day, the DR-HDH003S fits a damp space under 2,000 sq ft. It’s too small for a very damp or wet one. 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
A middle-of-the-pack power bill
Next to the median 19–28 pint model, this one costs $26 less to run in the United States over 11 years. That’s how long the DOE expects a portable to last. The thriftiest 19–28 pint model, the Knka PD30MA-20, would save $83 over those years.
Of the 155 certified 19–28 pint models, only 10 have a Wi-Fi app, the DR-HDH003S among them. You can change the setting from another room.

Ask for a noise figure
Our sources publish no noise level for the DR-HDH003S. If it runs where you sleep or work, ask for a figure in dB(A), with the distance it was measured from.
Uses 271 kWh a year, 13 kWh under the median of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Of the 155 certified 19–28 pint portables, 19 use less energy.
At 1.75 liters per kWh, it clears the federal minimum for its class by 35%.The DOE sets 1.30 L/kWh for portables rated 25 pints a day or less. Every unit made since June 13, 2019, must meet it.
Dreo’s next size up is the DR-HDH004S, rated 32 pints.That one uses 64 kWh a year more.
Sold since March 2026. Among 19–28 pint models, 95 of 155 came out earlier.
Not on the EPA’s Most Efficient list, which names 31 of the 19–28 pint models.
Another brand near this size: the Bufanli OL22-D076FFN3B1/FE, at 22 pints and 267 kWh a year.In the United States, this one costs $1 a year more to run.

in the United States
In 24 hours at full output, the DR-HDH003S pulls about 2.8 gallons of water from the air and uses about 6.0 kWh. That day costs $1.09 in the United States.
About 45 such days make up the EPA’s yearly estimate of 271 kWh. If yours runs at full output more often, every extra day adds $1.09.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the DR-HDH003S pulls out less than 22.09 pints a day.
Those 2.8 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 DR-HDH003S has.
