Our read
Who it suits
Rated 27 pints a day, the VAD25S1AWTS is sized for a very damp space under 2,000 sq ft. For a 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
Running cost won’t decide it
The DOE puts a portable’s average life at 11 years. Over that time, this model costs $2 less 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 $107 over those years.
No source we use gives a dB(A) figure for the VAD25S1AWTS. For a bedroom or an office, ask the seller for one, and for the distance it was measured from.
At 283 kWh a year, it sits 1 kWh below the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.

Among the 155 certified 19–28 pint portables, 68 use less energy.
The federal floor for its class is 1.60 liters per kWh. It reaches 2.01, or 26% more.That floor covers portables rated over 25 and up to 50 pints a day, for units made since June 13, 2019.
In the Vissani lineup, the next size down is the VADA22A4HWT, at 22 pints. The next size up is the VAD35S1AWTS, at 36 pints.The bigger one uses 100 kWh a year more.
On the market since August 2025, newer than 19% of the 19–28 pint models on the list.
Not on the EPA’s Most Efficient list, which names 31 of the 19–28 pint models.
The Midea MDUDA-25AEN8-BB0F is the closest size from another brand, rated 27 pints and 283 kWh a year.Both cost the same to run in the United States.

In 24 hours at full output, the VAD25S1AWTS pulls about 3.4 gallons of water from the air and uses about 6.3 kWh. That day costs $1.16 in the United States.
About 45 such days make up the EPA’s yearly estimate of 283 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 VAD25S1AWTS pulls out less than 26.87 pints a day.
Those 3.4 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 VAD25S1AWTS has.
