Dealing with sticky, uncomfortable air, musty odors, or signs of mold in your home? High humidity is more than just an inconvenience; it can damage your property, exacerbate allergies, and make your living space feel warmer than it is. A whole house dehumidifier offers a comprehensive solution, integrating seamlessly with your home’s HVAC system to maintain optimal humidity levels throughout every room. If you’re considering this essential home upgrade, Home Depot provides a wide array of options and resources to help you find the perfect system.
A whole house dehumidifier is a game-changer for maintaining a comfortable and healthy indoor environment. Unlike portable units that only tackle individual rooms, these powerful systems target your entire home, preventing moisture-related issues like mold growth, mildew, dust mites, and structural damage. By reducing the overall humidity, your home feels cooler and more comfortable, often allowing you to set your thermostat a few degrees higher and save on energy bills.
Understanding Different Types of Whole House Dehumidifiers
When exploring whole house dehumidifiers, you’ll primarily encounter models using a refrigeration-based system.
- Refrigerant Dehumidifiers: These units draw in humid air, pass it over cold coils filled with liquid refrigerant, causing moisture to condense and drip into a drain. The now-dry air is then reheated and circulated back into your home. This is the most common and efficient method for whole-house systems, effectively tackling large volumes of air. Their primary advantage is high efficiency in typical household temperatures.
- Desiccant Dehumidifiers: Less common for whole-house applications, these units use a moisture-absorbing material (desiccant) to pull water from the air. While effective in very low temperatures where refrigerant coils might freeze, they are generally not the go-to for average whole-house needs.

Choosing the Right Whole House Dehumidifier for Your Home
Selecting the ideal whole house dehumidifier involves more than just picking a brand. You need to consider several factors to ensure it effectively meets your home’s unique needs.
- Determining Your Home’s Needs: Start by assessing your home’s size, current humidity levels, and any specific problem areas like basements or crawl spaces. This will help you gauge the required capacity.
- Dehumidification Capacity (Pints/Day): This metric indicates how much moisture the unit can remove daily. Whole house systems typically range from 65 to 120 pints per day (PPD) or more. For homes up to 2,200 square feet, a 70 PPD unit like the AprilAire E070 might suffice. Larger homes up to 5,500 square feet could require units with 100 PPD or higher, such as the AprilAire E100. Matching the capacity to your home’s square footage and existing humidity is crucial for efficiency.
- Airflow (CFM): Cubic Feet per Minute (CFM) measures how much air the dehumidifier can process. Whole house units generally have ratings from 100 to 300 CFM. Consulting an HVAC professional can help ensure you select a unit with adequate airflow for efficient operation without over-drying your home.
- Energy Efficiency: Look for models with Energy Star certification. These units are designed to operate more efficiently, saving you money on electricity bills in the long run. The AprilAire E100 series, for instance, has earned the “Most Efficient” Energy Star designation.
- Drainage Options: Whole house dehumidifiers do not have internal collection tanks like portable models. They require a drainage solution.
- Gravity Drain: Water is routed through a hose to a nearby floor drain, sump pump, or utility sink. This is a low-tech, reliable option, as seen with the AprilAire E070.
- Built-in Condensate Pump: Essential if no suitable drain is nearby or if water needs to be pumped uphill or over a distance. Models like the AlorAir HDi90 feature a built-in pump for convenient water removal.
- Noise Level: While whole house units are generally quieter than multiple portable dehumidifiers, noise can still be a factor, especially if installed near living areas. Modern units are designed for relatively quiet operation, often comparable to a refrigerator.
- Key Features: Consider features that enhance convenience and performance:
- Adjustable Humidistat: Allows you to set your desired humidity level, and the unit automatically maintains it.
- Automatic Shutoff: A standard safety feature.
- Automatic Defrost Control: Prevents coils from freezing in cooler temperatures, crucial for basement or crawl space installations.
- Digital Display & Wi-Fi Connectivity: For easy monitoring and control.
- Filter Sensor: Alerts you when it’s time to clean or replace the air filter.
- Fresh-Air Intake: Some advanced models, like the Santa Fe Ultra98, can incorporate outdoor air to improve overall indoor air quality.

- Optimal Location: Most whole house dehumidifiers are installed near your existing HVAC system in areas like utility rooms, basements, or crawl spaces. This allows for efficient integration with your home’s ductwork, ensuring dry air is distributed throughout. If space is limited, professionals can often run dedicated ducting from a nearby location.
Maintenance Tips for Your Whole House Dehumidifier
Regular maintenance is key to extending the lifespan and ensuring the efficient operation of your whole house dehumidifier.
- Filter Replacement/Cleaning: Most units have washable or replaceable air filters. Check and clean or replace these filters every few months, or as recommended by the manufacturer, to maintain optimal airflow and prevent dust buildup.
- Coil Cleaning: Periodically inspect the dehumidifier’s coils for dust or debris. Gentle cleaning with a soft brush or vacuum can prevent buildup that reduces efficiency.
- Drain Line Inspection: Ensure the drain line is free of clogs and properly routed to prevent water backup and potential leaks. If you have a condensate pump, verify its function periodically.
