But then it raises the question: Which one should I buy? Rest assured. We have reviewed some of the whole house dehumidifiers and picked out the best ones available just for you!

Types of Whole House Dehumidifiers

Before jumping into our list of best whole-home dehumidifiers, let us differentiate between the two types of whole-home humidifiers that you pick from:

Big ducted whole-house dehumidifiers

Big ducted whole-house dehumidifiers have been built using an HVAC system, implying high dehumidification capacity. It guarantees to adjust the humidity in the house evenly. Although they tend to be in the upper limit of the prices – ranging around $1500 – they provide services that match it. A single dehumidifier can cover the entire house from the basement to the attics, so you don’t have to invest in multiple. 

Smaller portable dehumidifiers

These dehumidifiers are small and just knee-high in height; given their build, they are easily portable and can be taken to the required room. The entire house can be effectively dehumidified by taking various rooms, although the process will take quite a long time. They are super cheap, generally ranging from around $200 to $300. But to achieve the same level of efficiency as big ducted dehumidifiers, you need at least three to four working simultaneously.

How do you know if you need a whole-house dehumidifier?

You can spot the cues that your house needs a dehumidifier quite easily. If any of the following is evident, then it is time to invest in a whole-house dehumidifier. 

Bad smell in the air

One of the most obvious signs would be a musty and foul odor in the air. They usually emerge when mold or mildew starts growing on your walls, ceilings, or doors. They thrive in humid environments and leave almost permanent stains on places of growth. If this problem is there in several rooms, then it is advisable to go for a big ducted dehumidifier rather than several small ones. 

Condensation on the walls or glasses

If you start noticing condensation or fog on your walls or window glasses, then it means that your house has a high humidity level. If you leave the issue without rectifying asap, it can become the breeding ground for mold and mildews. 


Are your allergies suddenly acting up? This might be a sign to get a dehumidifier. Humidity houses a lot of health problems, and mold that grows, as a result, can be especially harmful. And if you don’t resolve this issue by buying a dehumidifier soon enough, it can lead to some fatal diseases. 

Appearance of mold

If you can already see mold growing across your house, then you need to buy the dehumidifier asap! The appearance of mold means that the problem has persisted for a long time and can mean the consequences can be harmful to your health and your house.


High humidity can be very uncomfortable. Your clothes would constantly wet, and your skin would be itchy. When it’s hot, you’ll have sweat to cool you when it dries eventually, but when the humidity is high, the perspiration never dries, which would leave your skin wet and sticky. It’s best to get rid of this problem using a dehumidifier!

Things to consider while choosing a whole-house dehumidifier

While buying a dehumidifier, there are certain things that you need to keep in mind. They are part of your investment, and it is best to pick one that suits you the best while also lasting long! Here are some considerations to buy the best whole-home dehumidifier:

Coverage Area

The first thing (and definitely the most important) is to consider how much area the dehumidifier would cover. If you want to cover the entire house, from top to bottom, then a big ducted dehumidifier would be the best choice. And if you require only a couple of rooms then go for the small portable dehumidifier.

Quality of build

As said, a dehumidifier is an investment that needs to last quite a while, there is absolutely no point in buying again and again. So, the build quality is the one thing you definitely need to consider. You need to be sure that the dehumidifier is of good quality and would last you years. Also, make sure to check the warranty period of the dehumidifier. 

Works at low temperatures

While buying the best whole-home dehumidifier you also need to keep in mind that on top of the dehumidifying house it also needs to raise the temp and make the house nice and warm. There is a desiccant dehumidifier that would work best under these conditions. Other dehumidifiers generally tend to stop working under certain temperatures but these continue to work until the desirable temp. 

Automatic restart

Getting up to start the dehumidifier, again and again, can be a real hassle. When you just want to stay in one place comfortably with a dehumidifier starting up on its own, it is best to go with one that comes with the system of auto restart (they are a little on the higher end but the features are worth it).

Automatic drainage

Be it whole house or portable they tend to generate quite an amount of drainage water in them. So be sure to get one that would automatically drain itself rather than a manual one as dehumidifiers stop working when the water level becomes high. It can be a chore to drain all the time so automatic draining dehumidifiers are the best option. 

Benefits of a whole-house dehumidifier

Besides dehumidifying the house dehumidifier also comes with various benefits:


The most obvious advantage of a whole-house dehumidifier over a portable dehumidifier would be the dehumidification of the entire house at the same time, without the need of taking the dehumidifier to every room. The whole house dehumidifier works with the HVAC system and takes the humid air and transfers dehumidified air through the vents to the entire house. This implies that a single dehumidifier would be able to give dry air to all the bedrooms, kitchen, attic, basement, and any other place that it has been attached to.  

Prevents the growth of mold

Another benefit that comes with whole-house dehumidifiers would be the prevention of mold. It only takes some amount of humidity for the mold to start growing. A slight change in the temperature and humidity is all it takes for mold to appear. What a dehumidifier would do is to keep the environment dry so that mold does not find favorable conditions to grow. 

Keeps the bugs away

Where there’s mold there are bugs. They attract certain types of bugs that multiply in the presence of mold. Besides being annoying, these bugs and insects can also cause health problems especially for people who have allergies. By employing a dehumidifier you can reduce the chances of mold growth and in turn keeping these bugs at bay.
