The Ultimate Whole House Dehumidifier Buying Guide

whole house dehumidifier

Excess moisture levels can be very problematic. Not only can high indoor humidity levels create the perfect conditions for indoor mold growth, they can also damage your wooden furniture. A whole house dehumidifier effectively lessens the impact of excessive humidity in your entire house all at once.

While portable dehumidifiers and conventional window air conditioners do a decent job of removing several gallons of water per day from your space, their day dehumidification capacity measures pale in comparison to what you get with a good whole house dehumidifier.

However, to use whole house dehumidifiers to the best effect, you need to know where to look.

Here are some of the best brands worth giving a try right now!

1. ALORAIR 55-Pint Crawl Space Commercial Dehumidifier for Homes

This energy-efficient powerhouse dehumidifier works fast — it’ll rid your home of musty odors and improve indoor air quality in almost half the time it takes portable whole house dehumidifiers.

We should warn you though that this #1 best whole home dehumidifier doesn’t come at the most affordable price. However, it more than makes up for this as it has a wider coverage space and comes with more features compared to the average cheap whole house dehumidifier.

It has become the go-to choice for experienced homeowners who value comfort largely because of its automatic defrosting, high-quality internal corrosion protection, efficient dehumidification process that saves on energy costs, and optional remote monitoring capabilities.

Their 100-pint commercial dehumidifier is a powerful unit capable of sucking out 12 gallons of water per day (or 96 pints per day) from a 5,000+ square feet home!

The advanced engineering that this unit boasts makes it remarkably efficient at helping you achieve the dry room temperature air you desire with minimal effort. As it has intelligent humidity control, you only need to set it once, and it’ll help you achieve the ideal conditions you want in your entire house consistently.

3. Abestorm 120-Pints Commercial Dehumidifier for Home With Drain Hose

If you want to achieve a healthy climate in the shortest amount of time possible in a small house, one of the most reliable units for moisture removal you can count on is this 120-pint commercial dehumidifier.

We’ll start by saying that just because it has a small day dehumidification capacity doesn’t mean it’s a cheap whole home dehumidifier. That being said, it’ll give you more value for your money than many single-room dehumidification units out there at the moment.

Capable of removing up to 7 gallons of water per day (or 56 pints per day), it has the ideal dehumidification capacity to rid your home of liters of moisture if it’s under 1,300 square feet.

Our favorite thing about this small coverage area dehumidifier is that it’s one of the more portable units you’re likely to find.

These commercial dehumidifiers have a small and safe continuous drain mode design that comes in handy if you have to move it from upstairs to downstairs or vice versa.

It’s built to last too, as it features the latest developments in corrosion-resistant technology.

We did notice an increased dB of noise output from the unit after a long period of operation, but it wasn’t at all unbearable.

Overall, from mold spores to water damage, this commercial dehumidifier will help you eliminate all moisture-related problems

These 386 cubic feet per minute or CFM dehumidifiers with enhanced dehumidification speed will make your entire home truly comfortable to live in again. They destroy the perfect conditions for mold growth thanks to a commendable water removal capacity that’s uncommon in many energy-efficient central dehumidifiers.

One of the many things that set the dehumidification process of this unit apart from the rest is the advanced engineering of its powerful condensate pump and drain hose.

The way the continuous drain hose is connected means that you can run the unit’s active dehumidification mode for as long as you want without worry!

This dehumidifier is also adapted for use in various locations, and you can use its continuous drain hose for crawl spaces, basements, and even marine environments.

Not only is it a great dehumidifier for crawl spaces, but you can also use it in a lot of other spots to prevent indoor mold growth as well!

Arguably, the biggest perk of these day dehumidifiers is that they have a simple plug-and-play feature that negates the need to incur any installation costs. You won’t have to buy any other materials either, as its drain hose is sufficiently long and it comes with a quality pump.

This air handler also makes maintaining an adequate humidity percentage easy because of how effective its intelligent humidity control is. Plus, in the event of a power failure, its memory kicks in and automatically restores your last settings when the power’s restored!

Other features that we love about this unit include its automatic drain and auto defrost function.

Other Whole House Units We Considered: 

Types of Dehumidifiers

Whole house dehumidifiers come in different types. Choosing the right dehumidifier type for your space can make all the difference.

The three main types of dehumidifiers, according to how they work, are:

Ventilation Dehumidifying Units

These types of units use a sensor controller that, once configured, will automatically turn on the exhaust fan when humidity levels rise above your preferred range.

However, they aren’t considered the best whole home dehumidifiers as their dehumidification operation tends to pull in some of the humidity outdoors. Also, their action can depressurize the room, something that’s potentially dangerous if they’re positioned in basements with gas furnaces.

Condensate Dehumidifying Units

These are the simplest dehumidifier types and work like your typical air conditioner.

These whole house dehumidifiers use extremely cold coils to turn the air moisture in your space into a liquid, which is then collected in their water reservoirs or allowed to drain away.

Desiccant Dehumidifying Unit

This last type of unit has a more than ideal dehumidification capacity.

They’re designed to use a drying agent such as silicone gel to enhance their water removal capacity and regulate too-high humidity levels. While they excel at enhancing indoor air quality, they’re not the most energy-efficient central dehumidifiers.

Reasons to Invest in a Whole Home Unit Over Portable Dehumidifiers

As we mentioned earlier, using portable dehumidifiers for single-room dehumidification isn’t a bad idea. But there are several reasons why you’re better off reducing humidity levels with a whole house unit.

Some of these are:

1. Whole House Dehumidifiers Are More Cost-Effective

The low initial cost of getting and installing portable dehumidifiers may make them appear like the more cost-effective option at first.

However, with increased use, you’ll quickly discover that the larger dehumidifiers give you more value for your money as they last longer and the average cost of running one is much cheaper.

2. Whole House Dehumidifiers Are More Efficient

If you only need day dehumidification capacity measures in one or two rooms, portable dehumidifiers work great.

However, if you’re looking to say goodbye to indoor humidity issues like mold growth and water damage in various parts of your home, only a whole house unit will do.

These larger moisture removal units will especially serve you well if you intend to stay in your current home for a long period of time. 

3. Commercial Dehumidifiers Don’t Require Intensive Maintenance

With portable dehumidifiers, constant maintenance is key if you don’t want your unit to start spreading the same microorganisms you’re trying to prevent.

While you do have to service whole house systems as well, you don’t have to do so as frequently, nor does it require as much effort.


1. Is a Whole House Dehumidifier the Same as an AC Unit?

No, it isn’t.

While they may have a similar operation process, the difference arises in the function they serve in the home. Your dehumidifier helps you lower moisture levels while your AC helps you keep the home cool.

An AC unit may do some dehumidification for you, but you’ll need a dedicated dehumidifier to do most of the heavy lifting.

2. How Much Does it Cost to Get a Whole Home Dehumidifier?

This depends on the type of unit you want to get, whether you’ll need professional installation services, and if you’ll buy any materials for the installation process.

3.       Can Whole House Commercial Dehumidifiers Improve My Health?

Yes, they can.

This is because they help reduce mold spores and eliminate harmful microorganisms like dust mites and other airborne pathogens.

Bottom Line

A whole house dehumidifier can make a great addition to your home. You don’t have to worry about the condensate water tank size with these units as you can just eject the excessive moisture collected through the floor drain.

While the best ones may require considerable financial investments at first, they usually pay for themselves as time goes on.
