10 Best Ducted Dehumidifier Systems 2026 in the United States

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 E070 is a high-capacity dehumidifier designed for homes up to 2,200 sq. ft., making it a solid choice for crawl spaces and basements that suffer from excess moisture. It can remove up to 70 pints of water daily, which is quite effective for controlling humidity to protect your home’s structure and reduce mold and mildew risks. The unit offers a decent airflow of 200 CFM and includes a quiet condensate pump, which is especially useful if a nearby drain is not available or if the unit is installed below the drainage point. Its energy use sits around 696 watts, so while it’s not the most energy-efficient model on the market, using the digital humidity control helps optimize operation and possibly reduces your cooling costs.

Installation is flexible thanks to included duct collars and a hanging kit, which also helps cut down noise and vibrations. The washable MERV 8 filter is an added bonus that cleans air without frequent replacements, though it needs yearly washing to maintain performance. Controls are straightforward with a digital interface and automatic on/off based on your set humidity, which keeps operation simple. The unit uses R32 refrigerant, which is environmentally friendlier than older options.

One limitation is that it has only one fan speed, so airflow adjustment is limited, and at 56 pounds, it might be a bit bulky for some DIY installations without help. The hanging kit’s vibration reduction suggests the unit can produce noticeable noise if floor-mounted. This model suits homeowners looking for a reliable, robust dehumidifier with versatile installation options and built-in pump features, but those prioritizing ultra-quiet or highly energy-efficient operation might want to explore other models.

The AprilAire E130 Pro 130-Pint Whole-House Dehumidifier is designed to meet the needs of both commercial and residential spaces up to 7,200 sq. ft., making it a robust choice for large areas like basements and crawl spaces. One of its standout features is its high capacity of removing up to 130 pints of moisture per day, which is ideal for very humid environments. Additionally, it boasts an Energy Star Most Efficient certification, ensuring it operates effectively while minimizing energy consumption, which is great for keeping electricity bills in check.

The smart sensing technology is a convenient feature, automatically starting dehumidification when needed, so you don't need to constantly monitor the humidity levels yourself. Its continuous drainage option also removes the hassle of emptying a water tray, as you can set it up to drain directly into a hose or floor drain. Built with durability in mind, it features corrosion-resistant aluminum coils and is manufactured in the USA, reflecting its high-quality construction.

On the downside, the unit is quite heavy, weighing in at 113 pounds, which might make installation and maintenance a bit cumbersome. It also has only one speed setting, which limits its flexibility in adjusting airflow. However, the user-friendly design, including its digital display and adjustable humidity control, makes it easy to operate. Prospective buyers looking for a powerful and efficient dehumidifier for large areas will find the AprilAire E130 Pro to be a strong candidate, especially if they prioritize energy efficiency and reliability.
