High humidity can cause an array of problems in any residential or commercial space. If you work in an office, warehouse, basement, garage, or a construction site, you might be facing greater dangers from humidity. Poor ventilation in the workspace may lead to excess moisture and a highly humid environment is susceptible to mold growth. At best, it can cause discomfort to both employees and customers in a commercial space. In the worst case scenario, prolonged exposure to high humidity can compromise your health and cause irreparable damage to your merchandise, electrical equipment, and other materials.
Commercial dehumidifiers are specifically designed to address these problems. These heavy-duty dehumidifiers operate in extreme temperatures and weather conditions to reduce moisture from commercial and industrial areas and maintain a healthy level of humidity. Choosing the best unit for you can be a daunting task. Luckily, I’ve scoured the web to come up with a comprehensive guide to help you. Start with the summary below.
Key Features of Commercial Grade Dehumidifiers
Dehumidifiers work by drawing in moist air, then releasing dry air back into the atmosphere according to the desired level of relative humidity that the device has been set to. You’ll need to choose between three different types of dehumidifiers: residential, commercial, or industrial. Industrial dehumidifiers are manufactured and tailored to large spaces like warehouses and factories. For more detail, check out our more detailed explanation here: Industrial vs. Commercial Dehumidifiers
Residential dehumidifiers are typically used in homes, however, they are usually made with lightweight materials and don’t have as much capacity as commercial dehumidifiers.
Many consumers also choose to invest in commercial dehumidifiers for their homes and offices because they tend to be built with more durable materials, can hold more water thus requiring less maintenance, and can manage larger spaces effectively. Let’s take a look at some of the differences between residential and industrial dehumidifier models:

When Do You Need a Commercial Dehumidifier
- Dehumidifiers remove moisture from the air and decrease humidity levels. They are particularly useful in areas where humidity collects like damp basements, garages, and storage spaces. It is absolutely essential to maintain optimum humidity levels within controlled environments in various industrial facilities such as factories, warehouses, and laboratories. Excess humidity in commercial areas results in corrosion, mold growth, and condensation. Structure maintenance and repairs can incur huge costs if humidity problems are not addressed quickly and efficiently.
- Working in a highly humid workspace can feel stuffy and uncomfortable. Mold growth and musty odors also come with excess moisture. Indoor amenities such as gyms, sports halls, restaurants, shops, and pools are prone to moisture problems. This kind of environment is not only unpleasant but also dangerous for employees. It may also scare away customers. You need a combination of the right temperature and humidity for a more comfortable experience.
- A commercial dehumidifier preserves structures, goods, and equipment. Merchandise of any kind may suffer damage if exposed to heavy amounts of moisture. High humidity may also cause electrical equipment to overheat and malfunction. Absorb excess water from the air to prevent the wallpaper from falling, protect electronic equipment, save important documents, and eliminate unwanted smells from sofas, chairs, and curtains.
- Unforeseen incidents like heavy rainfall and floods may cause destruction to structures. After experiencing water damage, it is important that you dry out the area affected within 48 hours. For restoration and repairs, a heavy duty dehumidifier is what you need. If your business is located in a place experiencing extreme weather conditions year round, it is a must to invest in a good commercial dehumidifier.
How To Choose the Best Commercial Dehumidifier
Commercial dehumidifiers are commonly used for drying applications in the cleaning, building maintenance, and restoration industries, and to control the humidity levels in offices. They vary greatly in terms of capacity and coverage. Some of the best commercial dehumidifiers have the capacity to absorb up to 160 pints of moisture at saturation or 90-100% relative humidity. This amount of power may consume energy as high as 1000 watts or more.
High-capacity dehumidifiers, as you may have already guessed, take a lot of space and tend to be noisy. Although some models may be used in different settings for different purposes, such as dehumidifying a huge garage or basement or even the whole house, keep in mind that most of these dehumidifiers are most useful in highly humid commercial spaces instead of residential houses.
Choosing the best dehumidifier for your workspace relies on many factors. Before you make a decision, you must first consider what you need a dehumidifier for. Different needs call for different types of dehumidifier. For commercial purposes, it is especially important to consider the cost of the initial purchase, the corresponding cost of your energy consumption, and other expenses you may incur in maintenance.
Features to Consider When Buying a Commercial Dehumidifier
Dehumidification Performance
The capacity or the amount of moisture the dehumidifier is able to pump out per day is the first thing you might want to consider. We included the maximum and AHAM capacities of each model to show you their full capabilities. You may notice that the maximum capacity has a bigger value. It indicates the largest amount of moisture the dehumidifier can extract from the air per day at ideal conditions of 90°F and 90% RH. The AHAM capacity is the amount of moisture collected at the average condition of 80°F and 60% RH, as recommended by the Association of Home Appliance Manufacturers.
To my knowledge, a standard 50- to 70-pint dehumidifier works well in most residential areas, but commercial spaces need a much higher capacity than that. It depends primarily on the size of the area and how wet the environment is, but for reference, an 85 PPD AHAM capacity should be around average performance for a commercial dehumidifier. For extremely wet conditions, I’d recommend you start at around 90 PPD for spaces above 2,500 square feet.
Coverage Area
You want a dehumidifier that can cover as much space as you can. This is important because the wattage you need in order to run your dehumidifier depends on the product’s energy efficiency and the amount of space that it has to cover. The airflow, measured in cubic feet per minute (CFM), is the rate in which it processes the air. A higher airflow rate typically means a larger coverage area, but this isn’t always the case. It can vary greatly between different brands and even different models within that brand. For good measure, a standard commercial dehumidifier can cover anywhere from 2500 to 8000 square feet. Some can go up to 10,000 square feet.
Built-in Pump
You want a dehumidifier that is as hassle-free as you can get. Most dehumidifiers give you the option to continuously drain water from the tank via gravity. However, you need to make sure the unit is positioned above a drain to prevent spills or leakage. With built-in pumps, you can operate your dehumidifier anywhere as long as the drain hose can reach the sink, drain, or window where you want to release the water. Just observe the height limit indicated if you need to position the hose vertically.
Low Temperature Operation
Basements and large spaces like warehouses can get extremely cold during the winter season. Even the best dehumidifiers may have some trouble working at low temperatures. Make sure you look for models that can handle temperatures that fall to 36°F or below.
Noise Level
Commercial dehumidifiers are big machines that can produce really loud noises. As a general rule, higher airflow rate comes with higher noise levels. For industry-specific purposes, this may not be a big deal. But if you work in an office or a commercial space that frequently takes in guests, customers, or clients, a noisy machine can be distracting and annoying for anyone. Always check the noise levels before your purchase. A model producing noise near 50 decibels or lower is recommended.
Built-in Humidistat
It is important to know the exact values of humidity in an industrial area. For storage facilities or laboratories, a little discrepancy can be a great deal of difference. A built-in humidistat keeps track of the humidity levels in your space, making it easy to adjust to your needs.
Portability
Given that commercial dehumidifiers are generally big, heavy devices, portability is an added bonus. If you’re in the water damage restoration business or working in construction sites, you want a dehumidifier you can easily stack, store, and transport from one location to another. For ease of movement within a large space, there are models designed with large wheels, handles, or casters.
If portability is a key factor for your application, check out our detailed evaluation of the Best Portable Commercial Dehumidifiers. There has been a lot of innovation recently in the portable HVAC space, and today you can even find Commercial Portable Air Conditioners to help maintain a comfortable space when and where you need it.
Warranty
Choose a model which offers reliable warranty and service should the need for repairs or other issues arise. A longer warranty period means the manufacturer is confident in the quality and durability of their product.
Build Quality
Commercial dehumidifiers are mostly built with steel or heavy-duty plastic, instead of the lightweight form of plastic present in standard home units. This makes the commercial models much more durable and more likely to survive tough handling even in extreme weather conditions.
Extra Features
Some extra features like the auto restart and shutoff can be really convenient. In the event of a power interruption, the dehumidifier will stop working. An auto restart function returns the dehumidifier to operation at your desired settings once power is restored. Some dehumidifiers like the AlorAir units also have an optional remote control function if you purchase the separate remote.
Types of Dehumidifiers
There are two main types of dehumidifiers that use different methods of collecting moisture from the air: refrigerant and desiccant. A refrigerant dehumidifier draws humid air and pumps out moisture. A commercial desiccant dehumidifier uses absorbent materials to collect moisture from the air until the maximum capacity is reached. For commercial purposes, refrigerant types are more commonly used.
Refrigerant Dehumidifiers
A refrigerant dehumidifier works with the same principle as your refrigerator, hence the name. It uses the refrigeration cycle to reduce humidity levels. A fan constantly draws the humid air and passes it through the cool metal plate. As more air is pulled in, the moisture condenses into water. This water is collected into a tank or pushed out through a drain or pump.
Since this type of dehumidifier uses refrigeration to extract water from the air, their performance declines dramatically in lower temperatures. This happens when ice forms on the refrigerant coils. Freezing can occur at temperatures about 65°F/18°C or below. Some refrigerant dehumidifiers, especially ones designed for commercial use, can still operate effectively at lower temperatures.
Under the refrigerant type, there are two kinds of commercial dehumidifiers, conventional and LGR.
Conventional Dehumidifiers
Conventional dehumidifiers can tackle most water damage restoration tasks. They can easily be transported and loaded into vehicles. They draw humid air from the room and pass it over through refrigerant coils until water condenses, while a heat pipe prevents frost from forming. The dry air is reheated and exhausted to the room to collect more moisture.
LGR Dehumidifiers
LGR stands for low-grain refrigerant. These dehumidifiers provide maximum power in removing moisture from the air. They feature a double cooling system that lowers the temperature of the air collected. This leads to more condensation, which in turn leads to more moisture pumped out and less moisture in the air that is returned to the room. For extremely wet environments, an LGR commercial dehumidifier is what you need.
Proper Usage, Maintenance and Storage of Commercial Dehumidifiers
When using a dehumidifier, it’s important to find the best location. Place it in a region where there will be an efficient air circulation. Keep it a few inches away from the wall or any blockage. Most of these machines work best at room temperature of 65°F. The motor can be burnt or frozen by extreme temperatures unless it’s specifically designed for this purpose.
Almost any dehumidifier comes with a filter to protect the machine and its components from dust, bacteria, and other allergens present in the air. This ensures that the unit only processes clean and healthy air. For every model there is a recommended period after which the filter must be cleaned or changed. Read the manual and follow the instructions carefully so that your unit can last long.
At freezing or nearly freezing temperatures, always check the coils for frost. Operating your dehumidifier in cool conditions may sometimes cause ice to build up inside the machine. This can compromise the unit’s performance and even cause permanent damage. Some models automatically defrost once ice is detected on the coils.
Before cleaning the unit, always turn off and unplug. Even with a built-in pump, you must wash the water container as it can still get dirty. You may use a vacuum to clean the insides to ensure that dust or debris don’t accumulate on the coils. Consult your manual for more specific guidelines and instructions.
Never turn on the machine instantly after turning it off. Wait for at least ten minutes to turn it on again. This time gap allows the machine some time to even out the pressure that was manufactured when the machine was operating. Apart from allowing the appliance less time to eliminate humidity effectively, turning the unit on instantly after turning it off can also cause damage to its compressor.
When your dehumidifier is not in use, place it in a designated storage until it is needed. First, turn it off and allow it to dry completely. Ensure that the power cord and drain hose are wrapped neatly. Store the unit in a clean dry space. When transporting from one location to another, make sure each unit is stacked properly.
