What Is a Commercial Dehumidifier?

It is also important to explain what exactly qualifies as a commercial dehumidifier. An industrial dehumidifier is one that is designed to remove large amounts of water and moisture out of the air. What separates this kind of humidifier from residential grade options is that it is specifically designed to give you an appliance that can handle large spaces and heavy amounts of moisture.

Even if you have a small office complex, the likelihood is that you could build up a large amount of moisture in the air, especially if you live and human environments. Finding a heavy duty dehumidifier can really help to improve the quality of the air and your business, making it significantly more comfortable for your employees and customers.

Who Are Commercial Dehumidifiers For?

You may be looking at this commercial dehumidifier review and asking yourself if this is for you? That is a good question. If you already know what to consider to buy a dehumidifier, then you won’t have any problem in making up your mind. But the truth is that this can be a great choice for any business or other commercial settings as well as for many homes. You might need this if…

  • New to the business world – if you are starting your own business for the first time, you want to make sure you’re getting off on the right foot. Having a commercial dehumidifier can help to make sure that your business and its products are not endangered from the effects of excess moisture.
  • A Company selling products stored in your warehouse – if you have your goods and products stored in a warehouse, especially in a climate where humidity is an issue, you will want to make sure you are protecting those goods so that they do not become damaged.
  • A company that has in-house employees (Almost all the companies that don’t operate online) – if you have people working in your business you will want to protect their health as much as protect the integrity of your products. Mold and mildew build up from excess moisture can cause serious respiratory problems for your staff, and so having a dehumidifier can help to improve their health and remove the potential for an illness that can lead to sick days or other issues.

How to Determine the Right Capacity of Dehumidifier You Should Buy?


In all the commercial dehumidifier reviews we examined, one of the essential aspects that any person making a purchase like this needed to consider was the amount of moisture that would be removed within their business or office during a 24 hour time period. This is about the capacity of the dehumidifier, which is one of the essential things for you to consider.

When making your decision, here are four things about the industrial dehumidifier that are related to the conditions of the building as well as the amount of capacity you need your commercial dehumidifier to handle:

Moderately Damp Conditions:

If the conditions of the business are such that there is a moderate amount of dampness, then you should look for a dehumidifier that can extract 10 pints of water within a 500 square-foot area. What this means is that for every 500 square-feet (approximately 46.45 square meters), 10 pints of water can be removed. A good formula is that for every additional 500 square feet you will need to add 4 pints of capacity. For a 1500 square feet commercial space, the dehumidifier will need to extract at least 18 pints of water.

Extremely Damp Conditions:

In extremely damp surroundings, the dehumidifier will need to handle at least 12 pints of water per 500 square feet. In this case, each additional 500 square feet will need to add five additional pints of capacity.

Wet Conditions:

In a space that has wet conditions, you will need to be able to collect 14 pints of water per 500 square feet. Each additional 500 square feet requires adding 6 pints of additional capacity.

Extremely Wet Humidity Conditions:

For these conditions, you will need to extract exactly 16 pints of water per 500 square feet. Add 7 pints of additional capacity per 500 square feet.
Since you can now determine the right pint capacity of your desired dehumidifier, you can go through our reviews of some other dehumidifiers as per your requirements. We will review the top 10 commercial dehumidifiers here:

What is My Recommended CFM & ACH?

To help you to determine what kind of dehumidifier you need, a little explanation of some terms will assist you in being able to make the proper kind of decision for yourself.


ACH, abbreviated as air changes per hour, tells you about how many times the air is pushed through the dehumidifier each hour. This will help you to determine the amount of airflow that is needed to dehumidify your space. Depending on the humidity levels of your space, here are the recommendations for the ACH rating you need:

Extremely Wet: – at this level, humidity levels might be from 90% to 100%, and you are likely to see large puddles or standing water. In this case, the recommended ACH is 6.

Wet: – humidity levels are between 80% and 90%, with visible stains, wet spots, and mold and mildew present. The ACH should be 5.

Very Damp: – where the humidity level is 70% to 80% and there is visible moisture on the walls and floors of your structure, as well as the smell of mildew. The recommended ACH is 4.

Damp: – the humidity levels at this rating are from 60% to 70%. You will feel dampness on the walls or even in the air, and a very musty smell within the complex. Humidity buildup is usually most common in basements or in crawlspaces. The preferred ACH is 3.


CFM is determined by the cubic footage of your structure and the ACH level. Multiply these two numbers together and divide the number found by 60 minutes. This will give you the recommended CFM you need for your commercial space. Even if you have the best appliance, you may find that this will lead you to purchase more than one commercial dehumidifier.

What to Look for in a Good Commercial Dehumidifier?

As Mentioned above, there are several factors to consider in determining what is the best commercial dehumidifier for your business or office. In creating this review, here are a few of the essential characteristics that you need to consider.

Coverage Capacity

The amount of space that the dehumidifier covers has a large expanse, covering from such spaces as 10,000 cubic feet and beyond. This is important because of the amount of energy that is needed to be able to run your dehumidifier will vary greatly depending upon the product’s energy efficiency and the amount of space that it has to cover. Be aware that this rating can vary greatly between different brands and even different models within that brand.

Build Quality

Most industrial dehumidifiers that you will find are built out of steel or heavy-duty plastic, while residential dehumidifiers are made with a lightweight form of plastic. This makes the commercial brand much more durable, even the commercial portable dehumidifier options. Because of the materials that are used, you will find that they are more likely to survive and thrive for a much longer period of time that residential options.

Low Temperature Operation

What makes the commercial dehumidifiers the best, is that they are made to help reduce humidity at much lower temperatures. If you think about it, the likelihood of the temperature being much lower in your warehouse is common in comparison to in your home. However, the industrial options are made to operate fully in these lower temperatures, reducing the humidity level below 35% even in temperatures reaching 32°.

Pint Capacity

If your business has a large space, you will likely need a capacity of at least 70 pints that can be contained in a 24 hour period of time. Anything below 50 pints is still regarded as a commercial dehumidifier as long is it is made of heavy-duty materials. Knowing what to consider before buying a 70-pint dehumidifier will be helpful for you.

Auto Restart

There may be instances where you have a power failure or some other kind of interruption, which can cause the dehumidifier to shut off. An auto restart function returns the dehumidifier to operation once power is restored.

Built-in Humidistat

Many of the best dehumidifiers come with built-in humidistats, which allow you to be able to control the amount of humidity within your structure. These respond to the amount of humidity or the temperature, regulating both of these factors through the appliance.

Automatic Drainage

While the capacity of the dehumidifier may be one of the important considerations, if there is an automatic drainage system included than this can remove the capacity concern. An automatic drainage system allows you to keep the dehumidifier running without having to worry about whether the storage basin is full.

Noise Level

In comparison to residential dehumidifiers, commercial options can be quite noisy. Even the very best appliance will be significantly louder than the residential option.

Low Maintenance

Whether you have purchased a crawl space dehumidifier or commercial dehumidifiers for basements, there are concerns related to maintaining your dehumidifier for optimal efficiency. If you find that it is difficult for you to be able to reach and have serviced, this means you need a dehumidifier that requires as little maintenance as possible, including one that is an automatic drainage system. For the portable options, this is not a concern, but you will need to consider this for many of the best commercial dehumidifiers.

How We Picked and Tested

Besides searching on the web to find reviews about the different commercial dehumidifiers on the market, we also had volunteers test the appliances and provide feedback and data.

How can you enhance the performance of your commercial dehumidifier?

While getting a commercial dehumidifier is a great option for you, you want to get the absolute best performance out of it. To make sure that this occurs, it is important that you regularly service and provide maintenance for your dehumidifier. This means that you should do such things as clean ducts, oil rotating parts, remove any debris, and make sure that all crawl spaces and air ducts are maintained and cleaned as well.

You need to understand that failure to properly maintain and clean these parts of your dehumidifier can lead to contamination and poor performance. It is quite common the rotating parts will wear down over time, so ensuring that you properly maintain and oil them will extend the life of your dehumidifier.

Additional Information

How much energy does a commercial dehumidifier consume?

According to the Department of Energy, the average dehumidifier uses 785 W of electricity. For you to be able to determine what amount of energy your dehumidifier may use, simply multiply the wattage by the number of hours and days that it has been in operation and divide this by a thousand. Then take the cost charged by your electric company in kilowatt hours, something that should be on your bill, and you will have your cost.

Does a dehumidifier produce disturbing noise?

The truth is that a commercial dehumidifier can make a great deal of noise. While there are some options out there that produce a significantly lower amount of noise, count on the fact that you are going to have some noise as the dehumidifier is in operation. It is quite comparable to that of an air conditioner.

How does a dehumidifier work?

The way that a dehumidifier works is actually quite simple. Warm air is brought in through the grill of the appliance in one side of the machine. An electric fan actually draws that air in, and as the warm air passes over the cold pipes that are contained inside the dehumidifier, condensation from the air builds up on these coils, thus removing humidity out of the air. The air that has been treated is pushed out the other side of the dehumidifier as new air is drawn in to continue the process. One last step is that the treated air where humidity has been removed is then heated to the temperature that you set by a heating element before it is returned to the environment around the dehumidifier.


ACH – stands for air changes per hour, which tells you how many times in an hour that air is drawn into the dehumidifier to be treated.

CFM – stands for cubic feet per minute, and is a measurement tool for the amount of moisture that can be extracted from an area during a minutes period of time.

COP – stands for the coefficient of performance, and is the ratio that measures the energy efficiency of the dehumidifier.

AHAM – stands for the Association of Home Appliance Manufacturers, and is used as a standard to determine a rating for dehumidifiers in a degree Fahrenheit temperatures with 60% humidity.

Hot Gas Defrosting

Humidistat – this is an instrument that indicates or controls the amount of relative humidity in the air.

HVAC – stands for heating, ventilation, and air conditioning, and is a term that will also include dehumidifiers.

Wrapping It Up

This is a lot of information for you to learn about commercial dehumidifiers, but now you have a real sense of not only how these machines work, what are key features of them, but also what would be good options for your home or business.

Before getting your own commercial dehumidifier, keep in mind that there are a few final things to consider. These include:

  • Cost
  • Performance
  • Need

Make sure that the dehumidifier you are purchasing is something that works for you, fits your needs, and comes in at a cost that is affordable. If you are finding that your current dehumidifier is not doing the job for you, then it may be time to upgrade. However, always consider that adding an expenditure that is not necessary or getting a commercial dehumidifier that will not deliver the kind of performance that you need is really counterproductive. Be smart in your decision-making process, and get one of these industrial appliances that really works for you and your budget. Also, you should know how to maintain a dehumidifier to get optimum service from your unit for years.
