10 Best Commercial Dehumidifiers 2026 in the United States

The AprilAire E100 Pro 100-Pint Whole-House Dehumidifier is a high-capacity, commercial-grade unit ideal for large spaces up to 5,500 sq. ft. Its significant 100-pint moisture removal capacity makes it suitable for basements, crawlspaces, or entire homes, effectively reducing humidity to prevent mold, mildew, and associated odors.

This model stands out with its energy-efficient operation, earning an Energy Star Most Efficient certification, meaning it uses less power, which is beneficial for both your energy bill and the environment. The absence of a water tray simplifies maintenance, as you can set it up for continuous drainage via a hose or place it over a floor drain. Smart sensing technology ensures the unit operates only when needed, maintaining desired humidity levels effortlessly.

Built in the USA, it boasts robust construction with corrosion-resistant aluminum coils, promising durability and longevity. At 64 pounds, it might be less portable compared to smaller models, and while it includes various control features like adjustable humidity control, automatic defrost, and a digital display, the noise level is not explicitly mentioned, which could be a potential drawback for noise-sensitive areas. The AprilAire E100 Pro is well-suited for commercial and residential use, ensuring effective humidity control in larger spaces, with easy maintenance and energy efficiency as significant advantages, though its weight may affect portability.

The Waykar 150 Pint Dehumidifier is designed for large areas up to 7,000 sq. ft, making it suitable for commercial, industrial, and residential use such as basements, warehouses, or offices. It boasts a strong moisture removal capacity of 150 pints per day, which is ample for controlling humidity in big spaces. Thanks to its ENERGY STAR Most Efficient rating, it delivers this performance while keeping energy consumption relatively low, helping to reduce electricity costs.

One of its standout features is the built-in pump, allowing flexible drainage options including upward drainage up to 5 meters. This is particularly helpful for spaces where gravity drainage isn't convenient. It also offers a sizable 7-liter water tank with a visible water level indicator, so you don’t have to remove the tank frequently. Control-wise, the unit is user-friendly with adjustable humidity settings (30%-80%), three fan speeds, a timer, and safety lock features. The automatic defrost and cleaning reminders add convenience and help maintain efficiency.

Portability is decent for a commercial unit at 39.5 pounds, with 360-degree rolling wheels that make moving it easier. The 500-watt power usage is reasonable for its size and capacity, though it may still impact your electric bill if used continuously. The design is modern and practical, but at nearly 40 pounds, it might be less convenient for frequent transport compared to smaller models. This dehumidifier fits well for users needing powerful, energy-efficient moisture control in large spaces, especially where flexible drainage is important. It combines strong capacity, smart controls, and portability with some trade-offs in weight.

The MOUNTO 310 Pints LGR Commercial Dehumidifier is designed for heavy-duty moisture removal, making it ideal for large spaces like basements and job sites. With a high capacity of up to 310 pints per day, it efficiently handles substantial moisture, suitable for water damage restoration and other demanding tasks. Its built-in condensate pump with a 15-foot lift head allows for continuous drainage, which is a big plus for users who want to avoid manual emptying.

Furthermore, the dehumidifier's automatic restart and memory function ensure it resumes operation after power outages, which is crucial for continual moisture control in restoration jobs. Advanced digital controls add to the convenience by providing precise humidity management and real-time monitoring of conditions. However, its energy consumption of 10.5A, while expected for such a high-capacity unit, might be something to consider for long-term use.

Additionally, the unit's weight of 125 pounds, despite being portable with wheels, may still pose some challenges during transportation. This dehumidifier operates efficiently with a COP of 2.9 L/Kwh, balancing performance with energy use. It’s best suited for professionals needing reliable dehumidification in large, high-moisture environments, but might be overkill for smaller, less intensive applications. If you need robust, continuous dehumidification with advanced features in large spaces, this MOUNTO model is a solid choice.
