Our read
Who it suits
On the ENERGY STAR table, the DH-70SI suits a damp space under 2,000 sq ft. For a very damp or wet one, the table asks for more. 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
Its power bill is close to the norm
A portable lasts 11 years on average, by the DOE’s count. In that time, this model costs $12 more to run in the United States than the median 19–28 pint model. The thriftiest 19–28 pint model, the Knka PD30MA-20, would save $121 over those years.
Its 290 kWh a year is 6 kWh more than the median for its size.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
No Wi-Fi app.Not listed as connected.
Tied for 117th of 155 certified 19–28 pint portables for low energy use.
Its efficiency, 1.79 liters per kWh, is 38% above the federal minimum for its capacity class.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.
Sold since June 2026. Among 19–28 pint models, 136 of 155 came out earlier.Certified in June 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 nearest size from another brand is the AlorAir Helios D35, rated 24 pints and 274 kWh a year.In the United States, this one costs $3 a year more to run.

in the United States
In 24 hours at full output, the DH-70SI pulls about 3 gallons of water from the air and uses about 6.3 kWh. That day costs $1.16 in the United States.
About 46 such days make up the EPA’s yearly estimate of 290 kWh. If yours runs at full output more often, every extra day adds $1.16.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the DH-70SI pulls out less than 24 pints a day.
Those 3 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 DH-70SI has.
