10 Best Aprilaire Dehumidifiers 2026 in the United States

The Aprilaire E100 Pro is a strong choice if you need a reliable dehumidifier for a large area, such as a basement, crawlspace, or an entire home up to 5,500 square feet. It has a high moisture removal capacity—100 pints per day—which means it can handle very damp spaces effectively. It’s Energy Star Most Efficient certified, so it uses less power compared to many other models, which helps keep your electricity bills lower. The unit is designed to run automatically, turning on when humidity goes above your set level, so you don’t have to constantly adjust it.

One helpful feature is its built-in humidistat and smart sensing technology, which maintain your target humidity without fuss. Drainage is convenient since it avoids messy water trays; you simply connect a hose or position it over a floor drain for continuous draining, reducing maintenance. The unit is made from corrosion-resistant materials, promising durability especially in damp environments.

The Aprilaire E100 Pro is quite heavy at 64 pounds and not very portable, so it’s best suited for permanent installation rather than moving between rooms. It also produces some noise during operation, which may be noticeable in quiet spaces. The single fan speed limits customization for noise or airflow preferences. While it covers large areas well, smaller rooms might find it oversized and less efficient. This dehumidifier is ideal for homeowners or businesses looking for a powerful, energy-efficient solution to control humidity in large or hard-to-treat spaces. Its automatic features and durable build make it a practical investment for those needing whole-house moisture control, especially in basements or crawlspaces.

The AprilAire E100W Smart Wi-Fi Dehumidifier is designed to handle large spaces, removing up to 100 pints of moisture daily and covering areas up to 5,500 square feet. This makes it a strong choice for basements, crawl spaces, or whole-house use where controlling humidity is important to prevent mold and damage. Its built-in Wi-Fi and app connectivity offer handy remote control and monitoring, which is great if you want to adjust settings without being near the unit.

The included condensate pump and drainage kit make installation flexible, even in tricky spots where drains are higher than the unit. It also comes with a MERV 11 filter, improving air quality by reducing allergens such as mold and dust. On the energy side, it carries the ENERGY STAR label, meaning it is designed to be efficient, helping keep electricity costs down while running. Although exact decibel levels are not specified, the pump is described as quiet, suggesting it is suitable for home environments without causing much disturbance.

One downside is its weight—64 pounds—making it less portable and more suited to permanent installation rather than moving it around frequently. While the smart features are a plus, they might be unnecessary for users who prefer a simpler, manual unit. This model fits well for homeowners needing a powerful, whole-home or large-area dehumidifier with smart controls and flexible drainage options, especially if air quality improvement is also a priority.

The AprilAire E070 Dehumidifier is designed specifically for crawl spaces and basements up to 2,200 square feet, removing up to 70 pints of moisture daily. This high capacity makes it well-suited for larger, moisture-prone areas, protecting your home’s foundation and wood from damage caused by mold, mildew, and rot. It features a built-in digital humidistat that allows you to set a desired humidity level, and the unit automatically adjusts to maintain it, helping to save energy by reducing strain on your air conditioner.

One of the standout features is its drainage system. The included quiet condensate pump makes it easy to remove water, even when the unit is installed below the drain level, which is common in basements and crawl spaces. The ability to hang the unit using the provided kit can reduce noise and vibration and save floor space. While it weighs 56 pounds, this setup is manageable for most DIY installations. The unit uses R32 refrigerant, which is better for the environment than older refrigerants, and comes with a washable MERV 8 filter that helps clean the air. It is not compatible with smart home systems, so remote control is not available.

The dehumidifier operates at 696 watts, which is typical for this capacity but might add noticeable electricity usage if run continuously. Hanging the unit reduces vibration noise, which is helpful in living areas nearby. The AprilAire E070 delivers strong moisture removal with flexible installation options and features like the pump and hanging kit. It is a solid choice for those needing a reliable, heavy-duty dehumidifier for basements or crawl spaces, though it requires a dedicated drain or use of the pump and does not offer smart controls.
