Best Dehumidifier for a Garage or Workshop
A 2-car garage typically needs a 35-pint dehumidifier; larger or damper garages need 50 pints. The Frigidaire 35-Pint ($220) handles standard garages, while the Midea Cube 50 ($260) covers large workshops. Prioritize continuous drain since you will not want to empty a bucket in the garage.

Understanding Your Needs
Garages collect moisture from wet vehicles, concrete floors, poor insulation, and outdoor air infiltration. The result is rust on tools, mold on stored items, and a damp smell that seeps into the house. Noise is rarely a concern in a garage, so prioritize capacity and drainage convenience. A continuous drain setup (gravity hose to a floor drain or pump to a utility sink) means you never have to think about emptying a bucket. Durability also matters since garages see wider temperature swings and more dust than indoor spaces.
Why These Picks
The Frigidaire 35-Pint handles standard 2-car garages (250-500 sq ft) and features a well-designed, spill-resistant reservoir. For larger workshops or garages with significant moisture, the Midea Cube 50 provides the capacity with a 4.2-gallon tank. If your garage lacks a floor drain, the GE 50-Pint with Pump solves the drainage problem.

Sizing Note
Garages get a 1.2x sizing modifier because concrete floors and poor insulation increase moisture load compared to finished interior spaces.
