Our read
Who it suits
Rated 25 pints a day, the DT251BWR0 is sized for a very damp space under 2,000 sq ft. For a wet one, the table asks for more. It uses more power than most models its size.
Capacity suggested for each case, read Oct 5, 2026. ENERGY STAR adds that it’s better to oversize than undersize.
Running cost
Costs more to run than most 19–28 pint models
It uses 24 kWh a year more than the median 19–28 pint model. Over 11 years, the DOE’s average life for a portable, that’s about $48 extra in the United States. The thriftiest 19–28 pint model, the Knka PD30MA-20, would cost $157 less.
No source we use gives a dB(A) figure for the DT251BWR0. For a bedroom or an office, ask the seller for one, and for the distance it was measured from.
Uses 308 kWh a year, 24 kWh over the median of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
No Wi-Fi app.Not listed as connected.
Among the 155 certified 19–28 pint portables, 151 use less energy.
The federal floor for its class is 1.30 liters per kWh. It reaches 1.71, or 32% more.That floor covers portables rated 25 pints a day or less, for units made since June 13, 2019.
The smallest portable certified under the LG name. Next up is the DT351BWR0, at 35 pints.That one uses 66 kWh a year more.
On the market since September 2026, newer than 99% of the 19–28 pint models on the list.Certified in September 2026, one of the 97 models certified in the last six months.
Not on the EPA’s Most Efficient list, which names 31 of the 19–28 pint models.
The Deye DYD-P30 is the closest size from another brand, rated 25 pints and 256 kWh a year.In the United States, this one costs $9 a year more to run.

in the United States
In 24 hours at full output, the DT251BWR0 pulls about 3.1 gallons of water from the air and uses about 6.9 kWh. That day costs $1.27 in the United States.
About 45 such days make up the EPA’s yearly estimate of 308 kWh. If yours runs at full output more often, every extra day adds $1.27.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the DT251BWR0 pulls out less than 24.99 pints a day.
Those 3.1 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 DT251BWR0 has.
