The Keystone 50 Pint Portable Dehumidifier is a compressor-based unit rated to pull 50 pints of moisture a day from rooms up to about 4,500 square feet. It has a 1.8-gallon tank, automatic shutoff when the tank fills, and casters for moving between rooms. It suits damp basements, crawl spaces and whole-floor humidity control. Against rivals it is a plain, budget-minded machine: fewer smart features and no pump, but the capacity and coverage match larger-name units. Owners say it dries a damp space well but runs loud and fills the tank quickly in very wet air.

Owners find the Keystone 50 Pint effective at drying basements and large rooms, and like the tank size and auto shutoff. The common complaints are noise and how often the tank needs emptying in very damp conditions.
