Whole-house dehumidifiers remove humidity from indoor air, reducing uncomfortable stickiness and mitigating the likelihood of mold growth that may trigger certain illness and cause damage to a home. If you live in a naturally humid region or are simply a fan of extra-long steamy showers, you may benefit from a dehumidifier.
The nice thing about whole-house dehumidifiers—also called “ducted” or “inline” dehumidifiers—is that they connect to the home’s HVAC system to remove moisture throughout every room in the house, not just one. They’re pricier than other types of dehumidifiers, and in many communities, local codes will require professional installation. But they’re usually pretty quiet and can help reduce cooling costs in warm weather seasons.
According to the EPA, optimal indoor humidity levels are between 30 and 50 percent. Ahead, learn what to look for when shopping for a ducted dehumidifier and find out why the following models are among the best whole-house dehumidifiers for today’s homeowners.

How We Chose the Best Whole-House Dehumidifiers
We researched over 20 models of whole-house dehumidifiers, assessing quality, operating capacity, and cost-effectiveness. While we took brand reputation into account, particularly for industry leaders such as AprilAire and Honeywell, we also explored newer brands that offered competitive pricing and strong buyer reviews. We were looking for models that were quiet, energy efficient, and required minimal maintenance.
For many, whole house dehumidifier cost is a pricey prospect—homeowners can expect to pay between $900 and $2,000 just for the unit alone. Professional installation can bring the final tally to an average of $1,300 to $2,800. The models in our lineup are well suited for several excess-humidity situations. Still, it’s always a good idea to consult with an HVAC specialist before purchasing one to ensure it’s correctly sized for a specific heating and cooling system.
Our Top Picks
For those looking to reduce the humidity level in their entire home, odds are that one of the whole-house dehumidifiers on this lineup will fit the bill. While the following models vary in price and the amount of living space they will effectively treat, each one is designed to reduce moisture in the air so the home’s occupants are more comfortable. We detail all the whole-house dehumidifier pros and cons in each individual review.
AprilAire E100C Pro 100-Pint Whole-Home Dehumidifier

What to Consider When Choosing a Whole-House Dehumidifier
As a pricey investment, a whole-house humidifier shouldn’t be an off-the-cuff purchase. Below, learn about the factors and features to keep in mind while shopping for a unit. Whole house dehumidifier pros and cons run the gamut–some relate to the type of unit while others are associated with the initial investment or operating costs. Still, the benefits of whole-house humidifier systems are substantial.
There are two main categories of dehumidifiers: portable and ducted. Whole-house systems fall into the ducted category and connect to a home’s HVAC ducting. When the furnace or central air conditioner is running, moist air from the house is pulled through the return air vents and then through the connected dehumidifier, where the moisture is removed and the dry air is heated or cooled and dispersed throughout the house via vents.
In addition to the different types, there are two main methods of dehumidification: refrigerant and desiccant. In general (although there are exceptions), the desiccant method is used for portable room models, and the refrigeration method is used in whole-house dehumidifiers.
- Refrigerant dehumidifiers work by cycling hot, humid air over a cold surface, usually coils filled with liquid refrigerant. When the hot air passes through the coils, it forms condensation and drips into the collection tank or out of the drainage tube into a floor drain. This is the preferred type of moisture removal found in a whole-house dehumidifier system.
- Desiccant dehumidifiers use chemicals that absorb moisture to pull water from the air as it cycles through the system. The water is collected in a tank or directed to a drain via a hose.
Dehumidification capacity indicates how much moisture a dehumidifier can remove from the air daily. It is measured by the number of pints of water removed per day. The capacity can vary—even for the same model—depending on existing humidity, desired humidity level, space size, and temperature. Some manufacturers provide a capacity metric for their dehumidifiers. The Department of Energy provides guidelines and regulates the process of capacity testing for manufacturers seeking certification.
While single-room dehumidifiers usually fall within the range of 25 to 40 pints of moisture removed daily, installed and ducted whole-house systems usually remove between 70 and 120 pints daily. It’s possible to use several room dehumidifiers and achieve the same dehumidification capacity as an installed whole-house dehumidifier. Going this route may make the most sense for renters or those planning to move soon.
Before purchasing a new whole-house dehumidifier, shoppers will want to take stock of the size of the space they want to dehumidify. Matching the size of the space to the capacity and coverage area of the dehumidifier is known as “sizing.” Accurate sizing is critical to achieving maximum energy efficiency and dehumidification effectiveness.
While capacity and coverage are related, they are not synonymous. Just because a dehumidifier has a high ppd rating doesn’t mean it’s automatically well suited to a larger home. Things such as the size of the unit and the amount of air it circulates factor into the coverage area as well, so check both ratings when comparing dehumidifiers.
Keep in mind that there is no such thing as a portable whole-house dehumidifier, because these units are designed to install on the return-air ducting of the home’s HVAC system. They are permanent fixtures.
Many manufacturers list their dehumidifier’s airflow rate in cubic feet per minute (CFM), but if it doesn’t appear on the product’s listing, don’t be surprised—it’s not a requirement. Generally, whole-house dehumidifiers come with 100 to 300 CFM ratings, with the larger and more powerful models at the upper end.
This is where the advice of an HVAC professional can come in handy because the goal is to have sufficient airflow to process the air in the home quickly and efficiently. On the other hand, if the airflow exceeds what is needed, the unit can remove too much moisture, resulting in dry, itchy skin and higher-than-necessary utility bills from operating an oversize unit.
Keep in mind that units with high airflow ratings may be noisier than those with lower ratings, so the goal is to balance coverage, capacity, and airflow.
The easiest way to ensure getting an energy-efficient unit is by choosing one with Energy Star certification. Another thing to keep in mind is the size of the unit. Something that’s too large for the space in question will cause energy waste, while something too small will cause the system to overwork itself, which lessens its longevity.
Lastly, some dehumidifiers come with smart sensors. Buyers can place the sensors in different areas of the home, and the dehumidifier will run only as needed to maintain the desired humidity level in those areas. In terms of long-term efficiency, modern, fully installed ducted dehumidifiers are more energy efficient than portable-room dehumidifiers, but they come with higher upfront costs.
Portable room dehumidifiers come with internal collection tanks—whole-house dehumidifiers do not. Still, all dehumidifiers remove water from the air, and that water has to have a place to go. Ducted whole-house dehumidifiers are designed with drainage ports, which can be used in two ways. The user can position the drain port directly over a floor drain, which is standard practice, or attach a drain hose and drop the end of the hose in a nearby floor drain.
That works well if the dehumidifier is installed in a basement or utility room next to the HVAC unit because the HVAC unit also produces condensed water that requires a drain. It doesn’t work as well when there’s no space to locate the dehumidifier next to the HVAC unit.
When that happens, the dehumidifier is often located in an adjacent room or below the HVAC unit in a crawlspace, and there may be no drain nearby. In those cases, the user must also install a separate condensate pump and run a drain hose from the dehumidifier to the pump, which then pumps the water to a remote drain or to the yard’s surface, where it can run off.
Helpful extras such as digital displays, remote-control ability, Wi-Fi connectivity, and internal filter-change warning systems make the dehumidifier more enjoyable to use. Wi-Fi connectivity or app controllability is a nice feature as it allows users to monitor the unit as it operates and turn the desired humidity level up or down as they choose.
A few whole-house dehumidifiers offer added features, such as a high-efficiency filter that removes airborne particles while removing humidity. Others may offer the option of attaching a fresh-air intake hose that brings outdoor air inside to help reduce stuffiness.
Purchasing a whole-house dehumidifier can be quite an investment, and shoppers might have some additional queries. Check out the most commonly asked questions and their answers below to help you make your decision.
Q. Do whole-house dehumidifiers use a lot of electricity?
Like most whole-house appliances, dehumidifiers can be energy intensive. Still, the ultimate cost depends on the ppm rating, the wattage of the unit, and the local cost of electricity. Those trying to get a good idea of the energy usage of a dehumidifier can use an online calculator to help predict the monthly fee. And keep an eye out for a dehumidifier with Energy Star certifications.
Q. Where is the best place to put a whole-house dehumidifier?
The best spot is close to the existing HVAC system because the dehumidifier must be tied into the ducting. In many homes, this means in a utility room or a basement. If there’s not enough available space right next to the HVAC system, a professional will install the dehumidifier nearby, sometimes in a crawl space, and run the ducting through the walls or floor to reach the HVAC system.
Q. How much does a whole-house dehumidifier installation cost?
A whole-house dehumidifier install usually costs between $1,300 and $2,800, including the price of the dehumidifier. Extra-large or powerful units can run higher.
Q. How does a whole-house dehumidifier work?
These units draw in humid indoor air, remove the moisture, and then expel drier air into the home via the home’s vent system.
