Our read

Who it suits

Rated 35 pints a day, the DT351BWR0 is sized for a wet space under 2,000 sq ft, or a damp one over. Its yearly energy use sits near the median, so weigh drainage, noise, and price.

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 374 kWh a year, the median for 29–44 pint models. The thriftiest of its size, the Deciuu LIBRA-RCS32(Y)-N4-3(B), would save $83 in the United States over 11 years. That’s the DOE’s average life for a portable.

Wi-Fi app

You’ll check it in person

Like 78 other 29–44 pint models out of 87, the DT351BWR0 has no Wi-Fi app on the EPA list. In a basement you rarely visit, plan to check it in person.

Ask before you buy

Ask about the pump, and about the cold

Neither figure is in our sources for the DT351BWR0. 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.

From the data

Where it stands

  • Uses 374 kWh a year, the median of its class.
  • Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
  • Tied for 40th of 87 certified 29–44 pint portables for low energy use.
  • Its efficiency, 2.01 liters per kWh, is 26% above the federal minimum for its capacity class.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.
  • LG also makes it smaller, the DT251BWR0 at 25 pints, and bigger, the DT501BKR0 at 50 pints.The bigger one uses 150 kWh a year more.
  • Sold since September 2026. Among 29–44 pint models, 86 of 87 came out earlier.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 1 of the 29–44 pint models.
  • The nearest size from another brand is the Hisense DH3526K1W, rated 35 pints and 363 kWh a year.In the United States, this one costs $2 a year more to run.

in the United States

A day of nonstop drying means 35.3 pints of water, about 4.4 gallons, for some 8.3 kWh. At the average home electricity price in the United States, the DT351BWR0 costs $1.52 to run that day.

The EPA’s yearly estimate, 374 kWh, adds up to about 45 days like that. Each extra day at full output costs another $1.52.

Those 35.3 pints come from a DOE test at 65°F and 60% humidity. Cooler air at that humidity gives up less water, so expect fewer pints in a cold basement.

Every day at full output leaves 4.4 gallons to get rid of. Check how the DT351BWR0 drains, since our sources don’t say.
