Our read
Who it suits
At 22 pints a day, the VADA22A4HWT fits a damp space under 2,000 sq ft. It’s too small for a very damp or wet one. Its running cost is close to the median, so drainage, noise, and price matter more.
Capacity suggested for each case, read Oct 5, 2026. ENERGY STAR adds that it’s better to oversize than undersize.
Running cost
A middle-of-the-pack power bill
Next to the median 19–28 pint model, this one costs $16 less to run in the United States over 11 years. That’s how long the DOE expects a portable to last. The thriftiest 19–28 pint model, the Knka PD30MA-20, would save $93 over those years.
Our sources publish no noise level for the VADA22A4HWT. If it runs where you sleep or work, ask for a figure in dB(A), with the distance it was measured from.
Its 276 kWh a year is 8 kWh less than the median for its size.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.

Tied for 24th of 155 certified 19–28 pint portables for low energy use.
Its efficiency, 1.70 liters per kWh, is 31% 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.
Vissani’s next size up is the VAD25S1AWTS, rated 27 pints.That one uses 7 kWh a year more.
Sold since September 2025. Among 19–28 pint models, 38 of 155 came out earlier.
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 Frigidaire FHDD2233Y1, rated 22 pints and 276 kWh a year.Both cost the same to run in the United States.

in the United States
In 24 hours at full output, the VADA22A4HWT pulls about 2.8 gallons of water from the air and uses about 6.2 kWh. That day costs $1.13 in the United States.
About 45 such days make up the EPA’s yearly estimate of 276 kWh. If yours runs at full output more often, every extra day adds $1.13.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the VADA22A4HWT pulls out less than 22.27 pints a day.
Those 2.8 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 VADA22A4HWT has.
