Our read
Who it suits
On the ENERGY STAR table, the ACDOSOP-NG100 suits a damp space under 2,000 sq ft. For a very damp or wet one, the table asks for more. Aeroid lists four models with the same EPA figures, so compare prices.
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 $2 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 $111 over those years.
The company that files it with the EPA lists four models under other brands with the same capacity, energy use, and efficiency. Among them are the Aeroid TDP070-G100, TDP070-G200, and TDP070-W100. Compare their prices and warranties before you choose.

Ask how loud it is
No source we use gives a dB(A) figure for the ACDOSOP-NG100. For a bedroom or an office, ask the seller for one, and for the distance it was measured from.

Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.

Among the 155 certified 19–28 pint portables, 78 use less energy.
The federal floor for its class is 1.30 liters per kWh. It reaches 1.75, or 35% 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 Airzentti name. Next up is the ACD155P-PG100, at 50 pints.That one uses 245 kWh a year more.
On the market since April 2026, newer than 71% of the 19–28 pint models on the list.Certified in August 2026, one of the 97 models certified in the last six months.

In 24 hours at full output, the ACDOSOP-NG100 pulls about 3 gallons of water from the air and uses about 6.5 kWh. That day costs $1.19 in the United States.
About 44 such days make up the EPA’s yearly estimate of 285 kWh. If yours runs at full output more often, every extra day adds $1.19.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the ACDOSOP-NG100 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 ACDOSOP-NG100 has.
