What Is Exactly Meant by a Whole House Dehumidifier?
The whole house dehumidifier may be referred to as a dehumidification system that sustains the overall moisture level of your entire house at the optimal levels. It serves as a convenient way of keeping your whole house comfortable, healthy and most important free of moisture.
There are various kinds of whole house dehumidifier systems but two of them are more prominent in comparison to others. Some of the models are directly connected to a house’s HVAC system and perform the dehumidification phenomenon through the already installed air ducts. The second kind, on the other hand, comprises of portable house dehumidifiers that are powerful enough to carry out dehumidification of your home’s entire area. Both these types slightly vary from each other on the basis of costs and performance.
Who Are Whole House Dehumidifiers For?
Regardless of the fact that you own an air conditioning system or not, having a whole house dehumidifier may come in useful for your household. Every house has places like laundry rooms and basements where there are excessive amounts of moisture. These rooms sometimes tend to upset the moisture levels of the entire house, thus creating different types of issues, such as the growth of mildew and mold, occurrence of water spots and moisture stains, etc. Having an out of balance humidity level in your house may lead towards propagation of several respiratory and skin related ailments. So the best course of action in such a scenario is to get yourself a whole house dehumidifier. A few of the people who might benefit from buying a whole house dehumidifier are discussed below.
People who have to empty their dehumidifiers’ condensate tanks continuously
Small, portable dehumidifiers usually come with small water buckets for storage of the condensate. Since whole house dehumidifiers work on the dehumidification of the entire house, they are associated with high levels of drainage. That’s the reason why these devices offer continuous drainage feature.
People who are tired of allergies
If you have been affected by some sort of allergy, you would know that it does not go well with extensive moisture. As a matter of fact, humidity higher than a certain level causes different allergies to propagate notably. Having the best whole house dehumidifiers can certainly ease things up for you in such a scenario.
People interested in balanced humidity levels for their entire house
It is common knowledge that the air that is best suited for breathing contains an optimum amount of moisture. So if you are interested in having a perfectly balanced breathing environment in your entire house, buying a whole house dehumidifier would be a good fit.
Houses with mildew and mold growth
Extensive humidity serves as a hospitable environment for the growth of mildew and mold. Having a whole house dehumidifier puts a stop to the propagation of unwanted organic materials immediately.
How to Determine the Right Capacity of Dehumidifier You Should Buy?
When looking for the best whole house dehumidifiers, it is important to make sure your unit is powerful enough to dehumidify the entire house effectively. Consider the following factors to figure that out.
Moderately damp housing conditions
If your house is moderately damp, it is recommended to get a dehumidifier that might dehumidify 10 pints or 4.73 liters of moisture from a covered area of 500 square feet or 46.45 square meters. You may add about 4 pints or 1.89 liters to this amount for every extra 500 sq. ft. or 46.45 sq. m. For instance, if you have a room that covers an area of 1500 sq. ft. or 139.35 sq. m., get a whole house dehumidifier system capable of extracting 18 pints or 8.51 liters of moisture.
Extremely damp housing conditions
If you are living in a house that suffers extremely damp conditions, it is advisable to get a dehumidifier strong enough to dehumidify 12 pints or 5.67 liters of moisture per 500 sq. ft. or 46.45 sq. m. You may add up an amount of 5 pints or 2.36 liters for each 500 sq. ft. or 46.45 sq. m.
Wet housing conditions
In case your living space is suffering from wet conditions, it is advisable to buy a whole house dehumidifier with a moisture capacity of 14 pints or 7.57 liters per 500 sq. ft. or 46.45 sq. m. You may also add another 6 pints or 2.83 liters per every additional square footage of 500 sq. ft. or 46.45 sq. m.
Extremely wet housing conditions
For houses that suffer from extremely wet conditions, get a top-rated whole house dehumidifier with the capability to extract 16 pints or 7.57 liters of moisture for every 500 sq. ft. or 46.45 sq. m. 7 pints or 3.31 liters may be added for every other 500 sq. ft. or 46.45 sq. m.
Now that you know what is the right pint capacity of the dehumidifier you are going to purchase, you can consider having a look at our reviews of other dehumidifiers depending on your requirements. In this article, we will be only reviewing top 5 whole house dehumidifiers:
What is My Recommended ACH & CFM?
ACH:
ACH stands for air changes per hour, which may be referred to as the no. of times the air passes through a dehumidification system every hour. This helps in figuring out the required airflow for dehumidifying the entire area properly. Some of the recommendations made on the basis of humidity levels are given in the paragraphs ahead.
Extremely wet conditions:
In case of extremely wet air conditions, humidity levels are usually somewhere in between 90% and 100% where standing water or puddles are often seen. So the optimum ACH in such a scenario is 6.
Wet conditions:
In case of wet climatic conditions, humidity levels lie somewhere around 80% or 90%. Wet spots, visible stains or mildew condition may also be experienced. So the optimum ACH should be 5.
Very damp conditions:
Humidity levels for such a scenario sustain in between 70% and 80%. Visible moisture sitting on your walls or the flooring may be seen along with a certain mildew smell. The recommended ACH is 4.
Damp conditions:
For rooms sustaining damp conditions, humidity levels are around 60% or 70%. The area produces a musty smell and feels pretty damp especially in the humid weather. Crawlspaces, as well as basements, usually experience such type of conditions. The optimum ACH for such a scenario should be 3.
CFM:
To calculate the optimal CFM (Cubic Feet Per Minute) and locate your best-suited dehumidification system, multiply the space’s cubic square footage (LxWxH) by the ACH level and then divide the result by 60 mins. If you cannot identify a dehumidification system having the right CFM level for your needs, you may buy two individual units.
Would I Be Better off with a “Whole House” Unit or a Couple of Smaller Models?
Numerous whole house dehumidifiers are currently available on the market. They claim to properly dehumidify massive spaces but their performance depends upon the airflow going on around the area of operation. In case the air present in your house finds it hard to conveniently flow from one part of your house to another, the performance of a whole house dehumidifier would reduce notably.
In such a scenario, the flow of air may be enhanced by making using of small portable fans or ceiling fans since it directs from different parts of the house to the dehumidifier easily. The other option would be purchasing two smaller dehumidification units and placing them in separate parts of the house.
What Makes a Good Whole House Dehumidifier?
When you are looking to purchase a whole house dehumidifier for your house, there are certain things that must be kept under consideration for making the best choice and enjoying the optimum benefits. The following factors can help you choose the right unit from numerous options where all claim to be the best whole house dehumidifiers.
Coverage capacity:
Coverage capacity is one of the most important considerations while buying a top-rated whole house dehumidifier. It is critical to make sure your potential purchase is strong enough to dehumidify your entire house properly. To learn about the appropriate coverage capacity as per your needs, you may refer to the recommendations made in the above section on How to Choose the Right Capacity for Your Dehumidifier.
Build quality:
Build quality is another important consideration while you are buying a whole house dehumidifier system. Some of these products are installed in your existing HVAC system while others are portable and may be moved around the house. You need to figure out which one of the two best suits your requirements and make the purchase.
Low temperature operations:
Having one of the best whole house dehumidifiers come in handy when you are interested in warming up the house in addition to dehumidifying it. Desiccant dehumidifiers deliver better performance while dealing with low temperatures. Compressor-based models, on the other hand, are not likely to operate below a certain temperature limit. So if your house experiences low temperatures, getting a desiccant dehumidifier might be a better choice.
Pint capacity:
Since you are looking for a whole house dehumidifier system, it is important to make sure it has a pint capacity large enough to dehumidify the whole space. Prefer a product with a pint capacity of 70 or more pints.
Auto restart:
Auto restart is a highly desirable feature when it comes to whole house dehumidifiers. In the events of power cut or other similar actions causing your dehumidifier to shut off, it should be capable of restarting itself on its own. So prefer a system that comes with auto restart feature.
Built-in humidistat:
Before making a buying decision for your new dehumidifier, you need to understand that the optimum humidity level for summers is in between 40% and 50% and in between 30% and 40% for winters. Sometimes you might want to switch above or below this optimum range for certain requirements, such as drying up your laundry. It is recommended to buy a whole house dehumidifier that features a built-in humidistat and allows you to adjust the humidity at required levels.
Automated drainage:
Since a whole house dehumidifier is supposed to dehumidify your entire house, it would be associated with the generation of lots of drain water. So get a system that comes with automated drainage that continues uninterrupted operation all the time.
Noise level:
Dehumidifiers can be associated with extensive noise levels especially when they are located somewhere near or inside your bedroom. Models with 2-speed fans not only operate at low noise but are energy efficient as well. So before making a purchase, it is recommended to test it for noise levels.
Air filters:
Some home dehumidifiers feature detachable air filters that come in handy while protecting the internal coils from dust and dirt. So it is recommended to get removable and washable filters that might be cleaned off easily.
Should You Upgrade Your Dehumidifier?
Both portable as well as whole house dehumidifiers are available on the market. If you are currently using a portable dehumidifier, switching it to a whole house dehumidifier would be a great choice. Unlike portable dehumidifiers, whole house dehumidification systems are associated with powerful operations and are capable of removing extensive moisture from your entire house.
The majority of the whole house dehumidifiers are installed into the existing HVAC system of your house. So they help you enjoy a noise-free dehumidification experience in comparison to that offered by portable ones. Last but not the least, having a portable dehumidifier with a small condensate bucket that remains full all the time might also be a sign for upgrading to a whole house dehumidifier.
How We Picked and Tested
Before writing this guide, we carried out tens of hours of research work to come up with legitimate information on different operational aspects of the mentioned products. The process of selection involved in the research comprised of practical tests performed by several volunteers.
For the 4 years that we have been running this website, we have researched on a number of whole house dehumidifiers. Better yet, we have tested their majority by ourselves. It would be wrong to say that the tested products are perfect and free of any possible refinements but they may undoubtedly be listed among the best choices out there.
About 2 months were spent by our team on testing these products under different circumstances to figure out the legitimacy of their performance. The products were tested both with and without their operation guides.
The performance of the tested products was measured by analyzing various features such as coverage capacity, pint capacity, usability, manufacturers, weight and size, appearance, drainage, noise levels, air filtration, automated shutoff, automated restart, low temperature operations and other similar factors that impact their performance the most.
Our Top Five Product List:
Our team carefully analyzed the products below for the features that matter most in a whole-house dehumidifier: real coverage area, moisture-removal capacity, drainage options, low-temperature performance, and — since this is the category where it matters most — how the manufacturer actually treats you when a unit fails a year or two in. Every product here is currently listed and buyable on Amazon; we verified ratings, review counts, and pricing before publishing.
Our Pick: AprilAire E080 Pro Whole-House Dehumidifier
Runner-Up: Waykar 150 Pint Whole-House Dehumidifier
Budget Pick: AEOCKY 6000 Sq. Ft. Whole-House Dehumidifier
Best Rated: AEOCKY 5500 Sq. Ft. Whole-House Dehumidifier
Also Worth a Look: Ivation 50 Pint Whole-House Dehumidifier
Our Pick: AprilAire E080 Pro Whole-House Dehumidifier
The Install-It-Once Option
AprilAire E080 Pro Whole-House Dehumidifier
Energy Star Certified and rated for whole homes up to 4,400 sq. ft., this is the only dehumidifier on this list actually branded 'whole-house' by its manufacturer. Priced above $1,500.
Why We Chose It as Our Top Pick
Every other product on this list is a plug-in, roll-it-into-place portable unit. This one is different. AprilAire is a long-established HVAC accessory brand — the kind of name your HVAC contractor already knows — and the E080 Pro is designed to be installed as a semi-permanent fixture, often tied into ductwork, for true whole-home humidity control rather than moved from room to room. If you want a single, install-once answer for your whole house rather than a fleet of portables, this is it.
DETAILED REVIEW
Capacity and Coverage
Rated to pull up to 80 pints a day across spaces as large as 4,400 sq. ft. — enough for a full basement plus main floor in most homes, or a large single-level layout.
Build Quality
It’s currently an Amazon’s Choice pick and Energy Star Most Efficient certified, with a 4.6-star average across a few hundred ratings — the strongest review average of any true whole-house-branded unit we found still sold on Amazon.
Ease of Use
This is not a plug-and-play unit the way the rest of this list is. It’s built for a proper install, which typically means running it past an HVAC technician or a handy DIYer comfortable with ducted systems, rather than rolling it into a basement corner and plugging it in.
Drainage System
Designed for continuous gravity or pumped drainage as part of a permanent installation, so there’s no bucket to empty once it’s set up.
Bottom line: if you want a permanent, whole-house solution from a brand your HVAC contractor will actually recognize — and the budget allows for it — this is the pick on this list built for that job specifically.
Get it on Amazon!
PROS:
Established HVAC brand, not a generic import
Energy Star Most Efficient certified
4,400 sq. ft. coverage, genuine whole-house design
Strongest review average of any whole-house-branded unit on this list
CONS:
Significantly more expensive than portable alternatives
Best suited to a proper install, not a plug-and-go setup
Runner-Up: Waykar 150 Pint Whole-House Dehumidifier
Runner-Up
Waykar 150 Pint Whole-House Dehumidifier
The Largest Portable Coverage Here
Waykar 150 Pint Whole-House Dehumidifier
Rated for 7,000 sq. ft. with a built-in pump for uphill drainage, this is the largest portable unit on this list and carries a strong track record backed by tens of thousands of ratings. Priced under $330.
Why We Chose It as Our Runner-Up
If you’d rather not deal with a ducted install but still need genuine whole-house coverage, this is the strongest plug-in option we found. It’s built for exactly this job — daylight basements, multi-level homes, or a main floor plus basement running as one zone — and its review base is the largest of anything on this entire list by a wide margin.
DETAILED REVIEW
Capacity and Coverage
Rated for 150 pints a day at saturation across up to 7,000 sq. ft. One owner running this in a half-finished daylight basement with vents open to the floor above reported keeping the lower level near 30% humidity and the upstairs in the mid-30s consistently through a full humid season — close to “set it and forget it” performance.
Drainage System
The built-in pump plus continuous gravity drain both work well according to owners, giving you flexibility whether you’re draining into a nearby sink or pumping up and out a window.
Build Quality
The honest pattern across Waykar’s lineup: strong performance for a long stretch, then for some owners a gradual decline in moisture-removal power after roughly a year and a half of near-daily use. The upside is Waykar’s support team has a documented habit of approving free replacements after a few diagnostic questions and photos — even after the standard warranty window has technically passed.
Bottom line: for genuinely large or multi-level whole-house jobs where a ducted install isn’t in the budget, this is the strongest plug-in option here — just register your warranty and stay on top of filter cleaning.
Buy It On Amazon!
PROS:
7,000 sq. ft. coverage, whole-house capable
Built-in pump for uphill/long-distance drainage
Largest review base of anything on this list
Warranty support extends goodwill beyond the standard window
CONS:
Performance can gradually decline with heavy long-term use
Needs regular filter cleaning to avoid internal dust buildup
Budget Pick: AEOCKY 6000 Sq. Ft. Whole-House Dehumidifier
Budget Pick
AEOCKY 6000 Sq. Ft. Whole-House Dehumidifier
Energy Star Most Efficient at a Fraction of the Price
AEOCKY 6000 Sq. Ft. Whole-House Dehumidifier
105 pints a day across 6,000 sq. ft. with genuine Energy Star Most Efficient 2024 certification, backed by thousands of strong ratings. Priced under $300.
Why We Chose It as Our Budget Pick
This is the best combination of coverage, certification, and price we found. It covers more square footage than our runner-up at a lower price, and it carries the same top-tier Energy Star Most Efficient certification you’d expect to pay a premium for.
DETAILED REVIEW
Capacity and Coverage
Rated at 105 pints a day in humid mid-summer conditions and 83 pints a day in a cooler, damp basement, covering up to 6,000 sq. ft. Reviewers running it in whole-home setups report pulling multiple gallons a day during peak humidity months.
Build Quality
Owners consistently praise the quiet compressor and solid build — one reviewer specifically noted the unit was insulated and sound-dampened well beyond what they expected at this price. The honest downside: a number of owners report the unit losing its ability to pull moisture somewhere between 9 and 12 months in, almost always traced to a refrigerant issue. The consistent silver lining is that AEOCKY’s customer service has a strong track record of replacing failed units quickly, sometimes overnight-shipping a replacement and extending the warranty as an apology, without asking for the old unit back.
Auto-Defrost
Equipped with an auto-defrost system built for cooler basements and crawl spaces below 65°F, so it keeps working through the conditions where cheaper units frost up and quit.
Bottom line: if you want AprilAire-level coverage and efficiency without the AprilAire price tag, and you’re comfortable registering your warranty in case you hit the same issue some owners did, this is the strongest value on this whole list.

PROS:
Genuine Energy Star Most Efficient 2024 certification
6,000 sq. ft. coverage at a fraction of AprilAire’s price
Quiet, well-insulated build
Responsive warranty replacement process

Some units lose moisture-removal power after 9-12 months
Smaller water tank than you’d expect for the capacity

The Newest Entry With the Best Average So Far
AEOCKY 5500 Sq. Ft. Whole-House Dehumidifier
105 pints a day across 5,500 sq. ft. with the highest star average of anything on this list, though on a smaller, newer batch of ratings. Priced under $300.
Why We Chose It
This is a newer entry from the same AEOCKY lineup as our budget pick, built on the same flagship platform, and so far it’s earning the highest star average of any product on this list. The review count is still modest compared to our other picks simply because it’s newer to the market, but the early feedback is consistently strong.
DETAILED REVIEW
Capacity and Coverage
Rated at 105 pints a day in peak summer humidity and 72 pints a day in a cooler basement, covering up to 5,500 sq. ft. One reviewer running it in a four-car garage said it was pulling enough water that they bought a second, smaller unit for their RV after seeing how well this one performed.
Build Quality
Shares the same 7mm copper tubing and “3+3” evaporator/condenser layout as our budget pick, just tuned for a slightly smaller footprint. Multiple owners specifically called out how quiet it runs even on high fan speed, describing it as barely noticeable in an occupied room. The one recurring complaint is the water tank running smaller than expected for the capacity, similar to its sibling model.
Ease of Use
Reviewers consistently describe setup as fast and simple, with one owner in a high-humidity climate reporting they raised their thermostat two degrees and still felt just as comfortable after installing it.
Bottom line: if you want the newest, best-reviewed unit in this capacity class and don’t mind a smaller sample size backing that rating, this is worth a serious look.
Check Price On Amazon!
PROS:
Highest star average of any product on this list
5,500 sq. ft. coverage, Energy Star Version 6.0 certified
Notably quiet even at high fan speed
Same proven core components as our budget pick
CONS:
Smaller review sample than our other picks, being a newer release
Water tank runs smaller than the capacity suggests
Also Worth a Look: Ivation 50 Pint Whole-House Dehumidifier
Also Worth a Look
Ivation 50 Pint Whole-House Dehumidifier
A Long-Running Name-Brand Option
Ivation 50 Pint Whole-House Dehumidifier
A built-in pump and 4,500 sq. ft. coverage from an established dehumidifier brand, backed by over a thousand ratings collected across several years on the market. Priced under $250.
Why We Chose It
Ivation has been selling dehumidifiers on Amazon longer than most of the newer brands on this list, and this model has accumulated a large, multi-year review history as a result — which gives you a more complete picture of long-term reliability than a newer product can offer.
DETAILED REVIEW
Capacity and Coverage
Rated to remove 50 pints a day (measured under the newer, stricter DOE standard, which the manufacturer notes is equivalent to the old 70-pint 2019 rating) across up to 4,500 sq. ft. One long-time owner in a 700 sq. ft. basement said it filled its bucket in about 10 hours flat and completely outperformed the 35-pint unit it replaced.
Drainage System
The built-in 16-watt pump can push water up to roughly 16 feet vertically, which is genuinely useful for basements without a nearby floor drain. This is also where the biggest complaint shows up: several long-term owners report the pump specifically failing after a year or two of use, even when the rest of the unit keeps working fine off the internal reservoir.
Ease of Use
Reviewers consistently mention the LCD display and caster wheels make it easy to monitor and reposition, and the auto-restart feature reliably resumes operation after a power outage without needing to be reset by hand.
Bottom line: a solid, long-proven whole-house option if you want a big brand name with years of reviews behind it — just keep an eye on the pump specifically if you’re relying on it for unattended, continuous drainage.

PROS:
Long multi-year track record with over a thousand ratings
Built-in pump handles up to 16 feet of vertical lift
Easy-to-read LCD display and caster wheels for portability
Reliable auto-restart after power outages
CONS:
Pump reliability is the most common long-term complaint
Noticeably raises room temperature while running, same as other compressor units
Maintaining Your Dehumidifier
To enjoy a long living and optimally performing dehumidifier, it is important to carry out the required maintenance on a regular basis. Some essential maintenance tips to increase your dehumidifier’s efficiency are given below.
Dehumidifier Placement:
While placing your dehumidifier in a room, it is important to make sure that it is at least 6 inches away from any walls or other obstacles so that the exhaust and air intakes might not get blocked. The room where you are willing to operate the device must sustain a temperature of 65 degrees F or more, unless you own a low temperature dehumidifier. Otherwise, the working mechanism of the dehumidifier might sustain different kinds of damages.
Humidistat adjustment:
The humidistat enables you to control the levels of humidity present in your room. It is recommended to keep the humidistat in between 40% and 50% which is known as the ideal level.
Protect your compressor:
The compressor installed in a dehumidifier may overheat in case of abrupt turning off and restarting of the device. It is recommended to wait for 8 to 10 minutes before turning it back on so that the pressure might be equalized properly.
Filter replacement:
Filters are installed in dehumidifiers to keep their internal mechanisms free of any allergens or dust particles. Therefore, it is recommended to replace the filter every once in a while so as to save your dehumidifier from any damages.
Glossary:
ACH
ACH stands for Air Changes per Hour. It refers to the times that the air passes through a dehumidifier in one hour.
CFM
CFM stands for Cubic Ft. per Min. It suggests the speed of air passing in or out of the dehumidifier.
AHAM
AHAM stands for the Association of Home Appliance Manufacturers
Humidistat
Humidistat is a controller that lets you control the level of humidity on your dehumidifier.
HVAC
HVAC stands for heating ventilating and air conditioning. It deals with the environmental comfort for homes and vehicles.
Wrapping It Up:
Whole house dehumidifiers serve as the best solution to issues associated with high levels of humidity. Making use of such a dehumidification comes in handy when you or one of your family members is suffering from some sort of allergies, skin issues, heart complaints or breathing issues. All you need to do is to get a whole house dehumidifier for your space, plug it in and enjoy the fresh air free of any unwanted, hazardous impurities or excessive moisture amounts. In simpler words, buying a whole house dehumidifier is one of the best investments you could ever make to improve your home environment and health.
