10 Best Ducted Dehumidifier Systems 2025 in the United States

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 E080 Pro 80-Pint Whole-House Dehumidifier is designed for robust performance in large spaces up to 4,400 square feet, making it ideal for basements, crawlspaces, and whole homes. With a capacity of 80 pints per day, it efficiently removes substantial moisture, helping to prevent mold, mildew, and structural damage.

Its airflow capacity, combined with smart sensing technology, ensures effective humidity control without constant manual intervention. Energy Star certification underscores its energy efficiency, meaning it will have a minimal impact on your energy bills and is environmentally friendly. The lack of a water tray to empty simplifies maintenance, as it supports continuous drainage via a hose or floor drain.

The unit is durable, constructed with corrosion-resistant aluminum coils, and comes with various accessories for easier installation, including duct collars and a washable filter. On the downside, it has a single-speed operation, which may limit flexibility in airflow control, and its weight (63 pounds) means it might be cumbersome to move. This dehumidifier is best suited for homeowners or commercial users needing reliable, energy-efficient moisture control in large spaces without frequent maintenance.

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.
