10 Best Garage Dehumidifiers 2025 in the United States

The MOUNTO 310 Pints LGR Commercial Dehumidifier is a robust and highly effective solution for managing moisture in large spaces, including garages, basements, and job sites. With a high capacity of up to 310 pints per day, it efficiently handles moisture removal in areas up to 5000 square feet. The built-in condensate pump with a 15-foot lift head facilitates continuous drainage, making it convenient for operation in below-grade spaces without the need for manual emptying. This feature, combined with automatic restart and memory function, ensures uninterrupted performance even after power outages, which is particularly useful in water damage restoration scenarios.

The advanced digital controls and real-time display of temperature and humidity allow for precise monitoring and adjustment, enhancing its usability in diverse environments. Energy efficiency is notable with a COP of 2.9 L/Kwh, although the power consumption is 1150 watts, which might be a consideration for energy-conscious users. Portability is enhanced by the durable roto-molded plastic housing and large wheels, despite its considerable weight of 125 pounds.

The built-in humidistat adds to its functionality by allowing automatic regulation of humidity levels. This dehumidifier is ideal for those needing a heavy-duty, reliable, and easy-to-maintain solution for large and challenging moisture control tasks.

The Waykar 150 Pint Energy Star Dehumidifier is a strong choice for anyone needing to dry large spaces such as garages, basements, or commercial areas up to 7,000 square feet. Its 150-pint daily moisture removal rate is quite powerful, making it suitable for very damp environments. It is energy efficient, certified as Energy Star Most Efficient 2024, which means it uses significantly less electricity than many other models and has a washable filter that helps reduce maintenance costs and supports eco-friendliness. The unit features a built-in humidistat with an auto comfort mode that keeps humidity at comfortable levels automatically, which is helpful if you want a set-and-forget experience. It offers three fan speeds and operates quietly—below 40 decibels on the lowest setting—so it won’t be disruptive in your garage or even in living spaces.

Portability is well addressed with wheels and handles, plus a neat cable wrap for storage. The 1.88-gallon tank has an auto shutoff to prevent overflow, and there’s an included drain hose option for continuous drainage, though you need to position the hose carefully to avoid issues. One downside is the relatively heavy weight (around 40 pounds), which might make moving it occasionally a bit cumbersome despite the wheels. Also, while it’s quiet at low speed, the higher fan settings may be noisier. This dehumidifier combines high capacity, energy savings, and useful features like auto defrost and overload protection, making it a reliable and smart solution for large, moisture-prone spaces like garages.

This 180-pint commercial dehumidifier is a strong choice for garages, large basements, and crawl spaces up to 8,000 square feet. Its high capacity means it can remove a lot of moisture daily, which is great for damp or humid environments. The built-in pump and included long drain hose make drainage easy and automatic, so you won’t need to empty a bucket manually. Energy efficiency is impressive here thanks to the modern R32 refrigerant system, helping keep electricity costs down while being more eco-friendly than older models.

The adjustable humidity control and clear LCD screen let you set your preferred moisture level easily, and features like auto defrost and automatic restart after power outages add convenience and reliability. Its compact size and handles make it fairly easy to move and fit into tight spots like crawl spaces or narrow garages. On the downside, it weighs 66 pounds, so it’s not the lightest unit around, and there’s no specific noise level mentioned, which might matter if you want a very quiet device.

This dehumidifier delivers strong performance and smart features, making it a reliable, heavy-duty solution for controlling moisture in large or hard-to-reach areas, though it may be more than needed for smaller home garages.
