10 Best Ducted Dehumidifier Systems 2025 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 E080 is a high-capacity whole-house dehumidifier designed for large spaces up to 4,400 sq. ft., making it a strong choice for basements and crawl spaces prone to excess moisture. It removes up to 80 pints of water per day, which is ample for commercial or larger residential use. Airflow at 185 CFM helps circulate dry air effectively through ductwork, supporting whole-home moisture control. Energy-wise, it is ENERGY STAR Most Efficient for 2024, so it should keep operating costs reasonable compared to other models in this capacity range.

The built-in digital controls allow you to set your preferred humidity level easily, and the unit runs automatically to maintain it, which is convenient for set-and-forget use. Noise levels are not explicitly stated, but hanging installation via the included kit can reduce vibration and sound, which is beneficial for quiet operation. Drainage is well handled with a quiet condensate pump included, allowing for flexible installation even where drains aren’t nearby, and it uses a bucketless design with direct drain options.

Installation is DIY-friendly, supported by detailed instructions and a hanging kit, while maintenance is simplified by a washable MERV 8 air filter, recommended to clean annually. The use of R32 refrigerant is a plus for environmental impact. Although the unit is on the heavier side at 63 pounds and uses a single-speed fan, it offers automatic defrost and restart features for reliability in cooler or varying conditions. This system suits homeowners or small businesses looking for a durable, efficient, and relatively easy-to-install solution to manage whole-home humidity and protect building structures from moisture damage.

The AprilAire E070 Pro is designed to remove up to 70 pints of moisture daily, making it suitable for homes or crawl spaces up to 2,200 square feet. Its compact size allows it to fit through tight crawl space doors and between joists easily, which is a big plus for spaces that are hard to access. The unit uses corrosion-resistant coils, helping it last longer even in damp environments.

It offers a smart, set-it-and-forget-it experience with a digital wall control (Model 76) that can be placed remotely, so you can monitor and adjust humidity levels from another part of your home. Continuous drainage eliminates the hassle of emptying water trays, which is convenient for long-term use. The washable MERV 8 air filter adds a level of air cleanliness, which benefits overall home air quality. Installation comes with helpful accessories like duct collars, tubing, and mounting hardware, but professional installation might be needed if you’re not comfortable with ductwork and drainage setup.

This dehumidifier is aimed at commercial and residential use and has one speed setting, so it may not adapt as finely to changing humidity levels compared to variable-speed models. The unit includes automatic defrost and overheat protection features to support safe and uninterrupted operation. This AprilAire model is a strong choice if you want a durable, easy-to-control dehumidifier for crawl spaces or basements that prioritizes effective moisture removal and simple maintenance. If quiet operation or advanced speed control is critical for you, there might be other options to consider.
