This model is ENERGY STAR certified, so it balances good energy efficiency for a unit of its size, helping keep electricity costs reasonable despite its high performance.

One standout feature is its smart Wi-Fi connectivity, allowing remote control and monitoring through a mobile app—convenient for busy households or second homes. It also includes a quiet condensate pump with all necessary installation parts, making draining flexible even if traditional drain access is difficult. The adjustable humidistat and automatic operation let you set your preferred humidity level without manual intervention, adding ease of use. The unit weighs 63 pounds and is relatively large, so it’s not very portable and might require professional installation or some effort to set up.

Although the unit is energy efficient for its category, the power draw is still notable at 612 watts, making it best suited for those needing strong dehumidification rather than casual use. The AprilAire E080W offers robust, smart, and reliable performance for large basement or whole-house applications, but keep in mind the size and power usage when planning installation.

The AprilAire E100 is a powerful dehumidifier designed for large basements or crawl spaces up to 5,500 square feet, removing up to 100 pints of moisture daily.

This bucketless design means no manual emptying, adding convenience.

Size-wise, it’s a bit heavy at 64 pounds and measures 26" wide by 15" high and 14" deep, so it’s not very portable but meant for fixed installation. The washable MERV 8 filter helps keep the air cleaner and can be reused after washing, saving replacement costs. It runs on a single fan speed and uses 828 watts, which is on the higher side, so it could use more power than smaller units. Installation might be somewhat complex since it includes multiple components like duct collars and a hanging kit, but detailed manuals provide guidance.
