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

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 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.


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.

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.
