10 Best Whole House Dehumidifiers 2025 in the United States

The AprilAire E130 Pro is a powerful whole-house dehumidifier designed for large spaces up to 7,200 square feet, making it a strong choice for basements, crawlspaces, or entire homes. With a high moisture removal capacity of 130 pints per day, it effectively controls humidity levels, helping prevent mold, mildew, and structural damage from dampness. One of its notable strengths is its energy efficiency; it’s Energy Star Most Efficient Certified, meaning it uses less electricity compared to many other models, which helps keep running costs down.

It features smart sensing technology that automatically turns the unit on and off depending on humidity levels, so you don't have to constantly adjust settings. The unit also offers convenient drainage options by allowing you to attach a hose or place it over a floor drain, eliminating the hassle of emptying water trays. Maintenance is straightforward with a washable MERV 8 filter included, which helps keep the air clean and the unit running smoothly. The build quality is robust, with corrosion-resistant aluminum coils made in the USA, ensuring long-term durability.

However, it is quite heavy at 98 pounds and fairly large in size, which might be a consideration if space or mobility is limited. The unit operates at a single speed, so it lacks variable fan speeds that some users might want for noise or energy savings. Commercial-grade units tend to be louder than smaller home models. This dehumidifier is particularly well-suited for those needing reliable, high-capacity humidity control in large areas who value energy efficiency and hassle-free drainage, though it may exceed the needs of smaller homes or rooms.

The AprilAire E100 Pro dehumidifier is a solid choice for those looking to manage humidity in larger spaces, such as basements or entire homes up to 5,500 square feet. One of its standout strengths is its capacity, as it can remove up to 100 pints of moisture daily, making it a powerful option for combating dampness. Being Energy Star certified, it operates efficiently, which can help save on energy bills over time - a significant advantage for environmentally-conscious users.

The unit features smart sensing technology, which automatically activates dehumidification when humidity exceeds preset levels, allowing for a 'set and forget' operation. This feature is particularly appealing for busy households or commercial settings where constant monitoring may not be feasible. Additionally, the continuous drainage option eliminates the hassle of emptying a water tray, making maintenance easier.

The E100 Pro does have some drawbacks. Its size and installation requirements may be more complex compared to smaller, portable dehumidifiers, which could deter some users. While it comes with installation manuals and various components for setup, those unfamiliar with home improvement tasks might find it challenging to set up without professional help. Also, while the noise level is relatively low for a unit of its size, it may still be noticeable in quiet environments.

In terms of maintenance, it features a washable MERV 8 filter, which is beneficial for prolonging the lifespan of the unit and ensuring cleaner air. However, regular cleaning is necessary to maintain its efficiency, which might be an additional task for some users. The AprilAire E100 Pro is a robust solution for those needing to manage humidity effectively in larger areas, but it may require more commitment in terms of installation and maintenance than smaller units.

The Santa Fe Ultra70 Compact Ventilating Dehumidifier is a versatile and efficient option for small homes, condos, or apartments. It stands out with its ability to remove up to 70 pints of moisture per day, making it suitable for areas up to 1800 square feet. This capacity ensures it can handle moderate humidity levels effectively. One of its major strengths is its compact design, which allows it to fit in tight, low-clearance spaces like basements, crawl spaces, and garages.

The flexible airflow configurations, with options for vertical or horizontal discharge, further enhance its adaptability to different installation scenarios. Additionally, it includes a MERV-13 air filter, which improves indoor air quality by capturing fine particles, making it beneficial for those with allergies or respiratory issues. The unit operates continuously and meets Department of Energy standards for efficiency, which can help keep energy costs reasonable.

Despite having a few limitations such as operating at only one speed and the need for regular filter maintenance, the Santa Fe Ultra70 is a strong contender for those looking to manage humidity in compact living spaces with the added benefit of enhanced air quality.
