Our read
At 25 pints a day, the TDW80B fits a very damp space under 2,000 sq ft. It’s too small for a 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
Next to the median 19–28 pint model, this one costs $6 more 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 $115 over those years.

Our sources publish no noise level for the TDW80B. If it runs where you sleep or work, ask for a figure in dB(A), with the distance it was measured from.

in the United States
In 24 hours at full output, the TDW80B pulls about 3.1 gallons of water from the air and uses about 6.3 kWh. That day costs $1.15 in the United States.
About 46 such days make up the EPA’s yearly estimate of 287 kWh. If yours runs at full output more often, every extra day adds $1.15.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the TDW80B pulls out less than 24.66 pints a day.
Those 3.1 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 TDW80B has.
