Top 3 Whole-House Dehumidifiers Reviewed
#1 AprilAire E080 Pro Dehumidifier: Best Overall
Why We Picked It
AprilAire’s E080 is an ENERGY STAR Most Efficient whole-house dehumidifier that removes up to 80 PPD and controls humidity in homes up to 4,400 sq ft.
The E080 can sit in a basement or crawl space and treat the whole home, or connect to ductwork for a ducted installation. Smart sensing starts dehumidification automatically when humidity rises above your target, so it runs only when needed. It is ENERGY STAR Most Efficient certified, removes up to 80 PPD and covers up to 4,400 sq ft. There is no water tray; a hose or floor drain handles condensate. Corrosion-resistant aluminum coils and US manufacturing round it out.
Key Specifications
- Capacity: Up to 80 PPD
- Coverage: Up to 4,400 sq ft
- Certification: ENERGY STAR Most Efficient
- Control: Smart sensing auto start
- Drainage: Hose or floor drain
- Weight: 63 pounds

#2 Santa Fe Ultra V100 Ventilating Dehumidifier: Best with Ventilation
Why We Picked It
Santa Fe’s Ultra V100 removes up to 100 pints a day and adds an 8-inch fresh-air port and MERV-13 filtration, so it dries, filters and ventilates the whole home.
Tight, modern houses often need both dehumidification and fresh air. The V100 handles both: it removes up to 100 pints of moisture daily at 80 degrees F and 60% humidity, and an 8-inch port mixes in outdoor air to help meet ventilation standards without extra equipment. MERV-13 filtration cleans the air, and a 385 CFM blower pushes it through long 8-inch duct runs or multiple registers. Auto defrost keeps it working down to 34 degrees F, and Santa Fe lists 6.4 pints per kilowatt-hour.
Key Specifications
- Capacity: Up to 100 pints per day (80 degrees F, 60% RH)
- Ventilation: 8-inch fresh-air port
- Filter: MERV-13
- Airflow: 385 CFM
- Low Temperature: Down to 34 degrees F
- Efficiency: 6.4 pints per kWh
| Pros | Cons |

Things to Consider
It is a ducted system; plan for an HVAC contractor.
Best For
This dehumidifier is best for tight, energy-efficient homes.

#3 AprilAire E130 Pro Dehumidifier: Best for Large Homes
Why We Picked It
AprilAire’s E130 is the brand’s largest whole-house dehumidifier, removing up to 130 PPD in homes up to 7,200 sq ft with ENERGY STAR Most Efficient certification.
The E130 is for large homes and very damp basements. It removes up to 130 PPD and controls humidity across up to 7,200 sq ft, and like the rest of the Pro line it uses smart sensing to start automatically when humidity climbs above the target. It is ENERGY STAR Most Efficient certified, drains through a hose or over a floor drain, and has corrosion-resistant aluminum coils. At 98 pounds it is a permanent installation rather than a unit you move around.
Key Specifications
- Capacity: Up to 130 PPD
- Coverage: Up to 7,200 sq ft
- Certification: ENERGY STAR Most Efficient
- Control: Smart sensing auto start
- Drainage: Hose or floor drain

What to Expect from Whole-House Dehumidifiers
Crawl space and whole-house dehumidifiers are built to run for months without attention. There is no bucket: water leaves through a gravity hose or a built-in pump, the coils are protected against corrosion, and auto defrost keeps them working in cool, damp spaces where a household unit would ice up and stop.
For more options, see our guides to AprilAire dehumidifiers and Santa Fe dehumidifiers. For single rooms, our portable compressor dehumidifiers guide covers bucket models. The product cards show the current price for each dehumidifier.
How to Choose Whole-House Dehumidifiers
Ducted or Stand-Alone
Whole-house units can sit in a basement or crawl space and dry it directly, or connect to ductwork to treat the whole home. Ducted installs need a contractor, a duct kit and sometimes a fresh-air connection, so budget for installation.
Size for the Space and the Moisture Load
Coverage claims assume a sealed space. An encapsulated crawl space with a vapor barrier needs far less capacity than a vented, wet one. If you have standing water, efflorescence on walls or a musty smell throughout the house, size up.
Look for ENERGY STAR
A crawl space unit may run thousands of hours a year, so efficiency matters more than purchase price over its life. ENERGY STAR models remove the same water with noticeably less power.
Check the Warranty
These units are an investment, and warranties vary from one to six years or more. A long warranty from a brand with US support is worth paying for when the unit will live where you rarely see it.
How We Evaluate Whole-House Dehumidifiers
We rank dehumidifiers on manufacturer specifications and listing details: rated capacity and the conditions behind it, coverage, drainage, efficiency, build and warranty. We kept only new, in-stock units and left out renewed listings and bucket-style household models. For whole-house units we weighed rated capacity, coverage and efficiency first, then filtration, ventilation and warranty.
Frequently Asked Questions
Is a whole-house dehumidifier worth it?
In humid climates, often yes. It controls humidity in every room, runs quietly out of sight and avoids several portable units with buckets.
Can a whole-house dehumidifier connect to my HVAC?
Yes, most can be ducted into the return or supply, or run with their own ducts. A contractor should design the install.
What humidity should a crawl space be?
Most experts aim for 45% to 60%. Below that wastes energy; above it invites mold and wood rot.
How much does a crawl space dehumidifier cost to run?
It depends on capacity, efficiency and how often it cycles. ENERGY STAR units and a sealed crawl space both cut running time.
Final Verdict
The AprilAire E080 Pro Dehumidifier is the best whole-house dehumidifier for most homes, ENERGY STAR Most Efficient with automatic control. For fresh-air ventilation and MERV-13 filtration, choose the Santa Fe Ultra V100 Ventilating Dehumidifier, and for very large homes, the AprilAire E130 Pro Dehumidifier.
