10 Best Whole House Dehumidifiers 2025 in the United States

The ALORAIR Basement/Crawlspace Dehumidifier is a robust option for those needing effective moisture control in large spaces like basements, crawlspaces, storage areas, and even commercial settings. With a high dehumidification capacity of 198 pints at saturation and 90 pints per day under AHAM conditions, it is well-suited for areas up to 2,600 square feet. This makes it a powerful tool for maintaining a comfortable and dry environment in sizable areas.

One of its standout features is the heavy-duty condensate pump that ensures smooth operation by continuously draining the collected water, eliminating the need for frequent manual intervention. The automatic defrost function is another plus, as it helps prevent frost buildup and keeps the unit functioning efficiently, especially in colder conditions. Energy efficiency is a strong point, with its Energy Star certification promising significant energy savings, potentially up to $250 annually. This could be a beneficial investment over time, especially for those looking to balance performance with energy consumption. The unit also offers remote control capability, adding convenience for users who need to operate it from a distance.

However, it's important to note that the dehumidifier is relatively heavy at 70.5 pounds, which might make installation and relocation a bit challenging. Additionally, while it is designed for quieter operation in insulated spaces, noise levels could still be a consideration for some users. The ALORAIR dehumidifier also comes with a five-year limited warranty, providing some peace of mind regarding durability and support. This product is an excellent choice for those needing high capacity and efficient dehumidification for large and potentially challenging spaces, though its weight and potential noise should be considered.

The AprilAire E080 is a powerful whole-house dehumidifier designed to handle spaces up to 4,400 square feet, making it suitable for large homes or commercial areas like basements and crawl spaces. Its 80-pint daily capacity effectively reduces high moisture levels, helping protect your home from mold, mildew, and damage to wood structures. One of its standout features is the ENERGY STAR Most Efficient 2024 rating, which ensures it runs efficiently and can help reduce energy costs, especially by easing the load on your air conditioner.

This model offers flexible drainage options, including a built-in condensate pump that quietly moves water away when a nearby drain isn’t available—very handy if your dehumidifier is placed below drain level. The hanging kit is a thoughtful addition for installation in tight spaces or flood-prone areas, reducing noise and vibration by suspending the unit instead of floor placement. Controls are user-friendly with a digital interface to set your desired humidity, and the unit automatically maintains that level. The washable MERV 8 air filter improves air quality by capturing particles, and maintenance is simple, requiring just an annual wash. Using the eco-friendly R32 refrigerant shows a positive environmental consideration.

The unit weighs 63 pounds, which might make installation a bit challenging for some, though the included hardware and instructions aim to simplify this. It operates at a single speed, which may limit flexibility in airflow control compared to multi-speed models. While exact noise levels aren’t specified, the hanging kit helps reduce vibration noise. The AprilAire E080 is well-suited for those needing strong, efficient moisture control over large spaces, with thoughtful features around installation and maintenance. It is a reliable, energy-conscious system that also helps improve indoor air quality, especially in moisture-prone areas.

The AprilAire E100 Pro Dehumidifier Bundle is a robust solution designed to manage humidity in large spaces up to 5,500 square feet, making it suitable for whole homes, crawl spaces, basements, and even commercial areas. With a capacity to remove up to 100 pints of moisture per day, it is well-suited for significant humidity control tasks. The bundle includes all necessary accessories, such as a drain hose and filters, which enhances its value proposition by eliminating the need for additional purchases.

Users will appreciate the 'set and forget' feature, which utilizes smart sensing technology for automatic operation, and the convenience of continuous drainage, negating the need for manual water tray emptying. This dehumidifier is energy efficient, certified by ENERGY STAR, and aims to minimize energy consumption while being effective in moisture removal. Constructed with corrosion-resistant aluminum coils, it promises durability, backed by a 5-year warranty.

However, its weight of 90 pounds implies it is not very portable. It offers a digital display and various automatic features like defrost and shutoff, and the maintenance involves managing washable filters. Given its impressive specifications and features, the AprilAire E100 Pro is a dependable choice for those needing extensive dehumidification, especially in larger or multi-room spaces.
