10 Best Ducted Dehumidifier Systems 2026 in the United States

The AprilAire E100 is a high-capacity ducted dehumidifier designed for whole-house use in spaces up to 5,500 square feet, making it suitable for basements and crawl spaces in larger homes. It can remove up to 100 pints of moisture daily, which is powerful enough to protect your home from damp-related problems like mold, mildew, and wood damage. The unit is fairly energy efficient, holding the ENERGY STAR Most Efficient 2024 rating, helping to keep electricity costs reasonable despite its strong performance.

Airflow is rated at 280 CFM, which supports effective circulation and moisture removal through existing ductwork or installation with the included hanging kit. This hanging option also helps reduce noise and vibration, useful if floor space is limited or you want quieter operation. Speaking of noise, while not explicitly measured here, the design includes features that minimize disruption, especially when suspended. Drainage is well thought out with a built-in quiet condensate pump and included tubing, so you don’t have to worry about manual emptying or nearby drains. This is a big plus for installations in lower areas like basements. The digital control panel is user-friendly, allowing you to set a preferred humidity level that the unit maintains automatically, simplifying the operation.

Installation is DIY-friendly with detailed instructions and all necessary components included, such as duct collars, mounting hardware, and a washable air filter. Maintenance is straightforward, with the washable MERV 8 filter helping keep the air clean, though it needs to be cleaned annually. The unit’s power consumption at around 828 watts might be higher than smaller models, but this is expected for its capacity. Also, it operates at a single speed, so there’s less flexibility in airflow settings. The size and weight (64 pounds) mean it requires some effort to install. This makes the AprilAire E100 a reliable and efficient choice for homeowners needing a whole-house dehumidifier for large or moisture-prone spaces, delivering strong capacity, smart controls, and convenient features to protect your home’s air quality and structure.

The AprilAire E100 Pro is a solid choice if you need to control humidity in a large home or commercial space up to 5,500 square feet. It can remove up to 100 pints of moisture per day, which is excellent capacity for preventing dampness, mold, and mildew in basements or crawl spaces. Its Energy Star Most Efficient certification means it uses power wisely, helping to keep energy bills lower compared to less efficient models. The unit includes smart sensing technology that automatically turns the dehumidifier on and off based on the humidity level, so you can set it and mostly forget it.

Drainage is easy because it supports continuous draining through a hose, eliminating the need to empty water trays manually. Installation is fairly straightforward for a ducted system, with included duct collars and drain fittings, though you might need professional help if you’re not comfortable with airflow connections. The aluminum coils resist corrosion, which adds to the product’s durability over time.

One small downside is that it only has one fan speed, so you won’t have much flexibility to adjust airflow noise or performance levels. Featuring a washable MERV 8 filter, this is a reliable, energy-efficient whole-house dehumidifier that’s built to last and easy to maintain, making the AprilAire E100 Pro a strong option to consider.

The AprilAire E100W is a powerful ducted dehumidifier designed to handle large areas up to 5,500 square feet, making it a solid choice for whole-house or crawl space use. With a capacity of 100 pints per day and an airflow of 280 CFM, it efficiently removes moisture to help prevent mold, pests, and structural damage. It’s ENERGY STAR Most Efficient for 2024, which means it uses energy wisely compared to many other units in its class. The unit offers flexible drainage options including continuous draining, which reduces maintenance hassles.

Installation is versatile, supporting different duct configurations, and it comes with helpful accessories like duct collars and a washable filter. Its quiet operation is user-friendly, with automatic on/off control based on humidity levels and an automatic defrost feature to keep it running smoothly. A major plus is the built-in Wi-Fi with Bluetooth pairing, allowing you to monitor and control the dehumidifier remotely through the Healthy Air App, which is convenient for keeping your home’s humidity balanced without needing to interact directly with the device.

Weighing 64 pounds, installation may require some effort or professional help. It runs at 828 watts, so while it is energy efficient, it is not the lowest energy consumer available. Some users might find the noise level tolerable but not the quietest on the market. The AprilAire E100W is well suited for homeowners seeking reliable, whole-home dehumidification with smart controls and strong capacity, though size and power usage should be considered based on personal space and comfort preferences.
