PLANNING ESTIMATE

Garage dehumidifier-size calculator

Estimate a broad nominal pints-per-day range. Low-temperature performance, drainage, air leakage, and water entry can change the actual requirement substantially.

Use the result as a starting range

Capacity labels are based on standardized test conditions. A cold garage may collect far less water than the label suggests. Continuous drainage, door-open time, and correcting liquid-water entry can matter more than choosing the next size up.
