As of 2015, the Frigidaire 70-Pint Dehumidifier and the GE 70-Pint Dehumidifier are two popular large-capacity dehumidifiers. Both of these products average over four stars in user ratings and consistently garner large numbers of reviews on Amazon.com and Home Depot.
While dehumidifiers are not usually sold specifically for use in garages, Home Depot indicates that a large-capacity dehumidifier is appropriate for large, damp and musty rooms such as basements or garages. These dehumidifiers have capacities of 60 to 70 pints or above.
Dehumidifiers come with different features and varying water removal methods. Some feature pumps that allow for uninterrupted use while others require manual emptying of the water collection chamber.
