10 Best Whole House Dehumidifiers 2025 in the United States

The AprilAire E080 Pro 80-Pint Whole-House Dehumidifier stands out with its impressive capacity to remove up to 80 pints of moisture per day, making it suitable for large homes up to 4,400 square feet. This high capacity is essential for preventing issues like mold, mildew, and wood rot, thus preserving both health and home integrity. Its ENERGY STAR Most Efficient certification highlights its energy efficiency, which means it can help you save on energy bills while also being environmentally friendly.

One of the convenient features is the 'set it and forget it' functionality, allowing you to set your desired humidity level and let the device automatically manage the dehumidification process without constant supervision. The lack of a water tray that needs manual emptying adds to the convenience, as it comes with continuous drainage options that simplify maintenance. The included Model 76 Wall Mount Dehumidifier Control offers remote management, essential for homes with crawl spaces, basements, or attics. This remote control feature adds flexibility, making it easier to adjust settings from different parts of the house.

Built to last, the device boasts corrosion-resistant aluminum coils, which enhance durability. Another plus is the washable MERV 8 filter, which is not only efficient but also reduces the need for frequent replacements. The unit weighs 63 pounds, which might make installation and relocation a bit challenging for some. Additionally, it offers only one speed setting, which might limit customization for specific needs. Despite these minor drawbacks, it comes with a reassuring 5-year warranty and is assembled in the USA, underscoring its quality and reliability.

The ALORAIR Basement/Crawlspace Dehumidifier is a robust option for those needing effective moisture control in large spaces like basements, crawlspaces, storage areas, and even commercial settings. With a high dehumidification capacity of 198 pints at saturation and 90 pints per day under AHAM conditions, it is well-suited for areas up to 2,600 square feet. This makes it a powerful tool for maintaining a comfortable and dry environment in sizable areas.

One of its standout features is the heavy-duty condensate pump that ensures smooth operation by continuously draining the collected water, eliminating the need for frequent manual intervention. The automatic defrost function is another plus, as it helps prevent frost buildup and keeps the unit functioning efficiently, especially in colder conditions. Energy efficiency is a strong point, with its Energy Star certification promising significant energy savings, potentially up to $250 annually. This could be a beneficial investment over time, especially for those looking to balance performance with energy consumption. The unit also offers remote control capability, adding convenience for users who need to operate it from a distance.

However, it's important to note that the dehumidifier is relatively heavy at 70.5 pounds, which might make installation and relocation a bit challenging. Additionally, while it is designed for quieter operation in insulated spaces, noise levels could still be a consideration for some users. The ALORAIR dehumidifier also comes with a five-year limited warranty, providing some peace of mind regarding durability and support. This product is an excellent choice for those needing high capacity and efficient dehumidification for large and potentially challenging spaces, though its weight and potential noise should be considered.

The ALORAIR LGR Commercial Dehumidifier is a robust option ideal for large spaces, particularly suited for industrial purposes such as flood repair and basement drying. With a substantial capacity of up to 180 pints per day at saturation, it can cover areas up to 2,300 square feet, making it efficient for significant dehumidification needs.

Its compact design is a plus, as it can fit into crawl spaces and other confined areas, facilitated by two carrying handles for easy positioning. The built-in pump and 19.6 ft drain hose enhance the convenience of automatic drainage, reducing manual intervention. Users will appreciate the plug-and-go operation, with features like AUTO ON/OFF, memory starting, auto-restart on power failure, and auto defrost that allow for minimal supervision.

Energy efficiency is marked by its continuous operation mode and 646.3 watts power consumption, although some users might find the noise level higher due to its industrial nature. The 5-year limited warranty and professional customer support add a layer of reliability. However, being a commercial model, it may be overpowered for smaller residential needs, and its 64.3-pound weight can be a drawback for some users when moving it around.
