AprilAire E070W Smart Wi-Fi Crawl Space Dehumidifier, 70-Pint Commercial Whole-House Dehumidifier for Basement, Crawlspace & Home up to 2,200 Sq. Ft. with Pump, Drain Hose, Hanging Kit, MERV 11 Filter
The AprilAire E070W is a powerful crawl space dehumidifier that removes up to 70 pints of moisture daily, making it suitable for spaces up to 2,200 square feet like basements and crawl spaces. Its capacity is well matched for larger or whole-house applications, helping prevent mold, odors, and wood damage effectively. The built-in Wi-Fi connectivity is a standout feature, allowing you to monitor and adjust humidity levels remotely via an app, which adds convenience especially for busy households or second homes.
It comes with a quiet condensate pump, which is helpful if gravity drainage isn't possible, and includes all installation accessories like a hanging kit and MERV 11 filter. This makes setup easier without extra trips to the hardware store. The unit’s automatic features, such as moisture control, defrost, and shutoff, help maintain optimal performance without constant attention.
The unit is relatively heavy (56 pounds) and its size (12.5" x 25" x 12.5") might limit portability or placement flexibility in very tight crawl spaces. Energy use at 696 watts is moderate but not the most efficient available, so electricity costs could add up if run continuously. The inclusion of a quiet pump suggests moderate sound that may be noticeable in very quiet areas.
This dehumidifier is a solid choice for those needing strong moisture control over a large area with smart features and convenient installation options. It suits homeowners looking to protect their crawl spaces or basements while enjoying remote control capabilities, though it may be less ideal for small, cramped spaces or those highly concerned about energy consumption.

AprilAire E080 Pro 80-Pint Whole-House Dehumidifier, Energy Star Certified, Commercial-Grade for Basement, Crawlspace or Whole House up to 4,400 sq. ft.
Most important from
243 reviews
The AprilAire E080 Pro is a solid choice for anyone looking to manage humidity in crawl spaces, basements, or even whole homes. With an impressive capacity of 80 pints per day, it can effectively handle spaces up to 4,400 square feet, making it a strong contender for larger areas. One of its major strengths is its energy efficiency, being Energy Star certified, which not only helps lower energy bills but also benefits the environment. Users will appreciate the smart sensing technology that automatically activates dehumidification when humidity exceeds the set target, allowing for a 'set and forget' approach.
The drainage options are convenient, as it eliminates the need for manual emptying by allowing continuous drainage through a hose or floor drain. This feature is especially beneficial in maintaining low humidity levels without extra hassle.
However, potential buyers should note that it is somewhat bulky, weighing 63 pounds and measuring 14 x 26 x 15 inches. While it is designed for durability with corrosion-resistant coils, its size may present portability challenges, especially for those who might want to move it around. Additionally, it operates with a single-speed setting, which could be limiting for users looking for customizable airflow options. The digital display and built-in humidistat add to its functionality, though the setup process may be complex for some based on their experience level with home appliances. The AprilAire E080 Pro excels in capacity, efficiency, and automated features, making it an excellent choice for larger living spaces, though its size and setup may require consideration.
