Commercial Dehumidifiers

Commercial or industrial models are built to serve the same purposes as any other residential dehumidifiers, only that they are capable of covering a much larger area. These machines are the perfect choice for larger rooms, warehouses, industrial plants, high schools and so on, and they are used to prevent any possible damages caused by excessive moisture. Although they are more expensive than the residential models, they offer great results when it comes to capturing moisture and providing a healthy work environment. Now let’s see which are the products worth investing in.

  • Direct draining of moisture through the included hose ensures a mess-free environment.
MERV 8 Filter

To further enhance indoor air quality and to upkeep the operation of the device in a perfect shape, it features a washable MERV 8 filter. The good news is that it doesn’t need a lot of tending to, requiring your attention only once per year. There will come a point when you have to replace it, but a few years will pass until this expense is needed. As it stops the dust and impurities from the air that enters the machine from affecting internal parts, it prolongs its lifespan, so this is a part that you must pay attention to and take care of properly as it protects your acquisition, as well as your health.

In case the drain is not connected, it will automatically turn off when the tank is full to avoid overheating or spilling the water. A 1-year warranty covers its components except for the circuit board. To protect it, you must install a surge protection and a dedicated power circuit that will guard it in the case of a power failure.

What We Like What We Dislike
  • Digital display allows you to conveniently monitor temperature and humidity levels
  • Heavy duty compressor ensures a lengthy, problem-free operation
  • Designed to withstand operating in low temperatures
⇒Not the best price-quality ratio possible

Not the best looking model out there, but certainly one of the best when it comes to its performance, the Ideal-Airis the purchase you must make as it can withstand intense use for many years. Thus, your money are well spent on it.


Things to Know

Dehumidifiers designed for industrial use are stronger and more durable than other dehumidification devices are and therefore tend to be more expensive. These models are mainly made of steel or heavy-duty plastic, so they will certainly last for years. High humidity and mold often come from lack of central air system. However, using an industrial device can help eliminate high relative humidity levels, saving time, money and energy cost at the same time. Furthermore, it will help you maintain a healthy work environment for employees. Plus, they are very popular due to their ability to eliminate musty smells and reduce condensation and mold. However, industrial models were specially designed for large residential places in humid climates, like crawlspaces, garages, basements and pool areas. They are able to remove up to 160 pints and reach an array of square footage. As such, you need to take into account both the square foot coverage and pint capacity when purchasing the device.

Overall score


Industrial or Residential – Which one to Pick?

As the name itself suggests, it is designed for large spaces like office buildings, workshops, large market houses, and even factories where the air humidity could reach alarming levels. The residential type is designed for home use because it is smaller, less energy consuming and more appropriate for small-scale use.

  • Choosing between industrial and residential devices is related to your dehumidifying needs. Before picking a model, you must analyze some aspects to see which one would best fit the area where you will place it. Firstly, you should measure the room and decide how big it must be in order to handle all the humidity. For very large rooms like working spaces, market houses, large basements or garages, you will need an industrial model that is more powerful than a residential one.
  • However, not every large room needs one because there are also bigger residential models that can handle the space. You need to take into account the energy consumption as well when choosing between the two models. Getting a large model in a room too small will lead to energy waste while picking a model that is too small for the room means it will work around the clock in order to handle all the humidity.
  • You also need to keep in mind the operating time. Industrial models are powerful enough to handle heavy-duty use without showing any sign of overburdening. Therefore, if you won’t be able to supervise the machine and perform regular maintenance, you are better off with an industrial model with auto shut-off, automatic pump-out, and a built-in thermostat.


Pros and Cons

As with any other purchase you make for your house, buying an industrial humidity reducing device has its good and bad sides. An educated purchase implies knowing both so here are the main advantages and disadvantages of these large size devices.


  • The large absorption capacity

    By far, the biggest pro of owning one is the extended absorption capacity that makes it great for use in unlived rooms. Thanks to the large water tank and the ability to evacuate the water, you won’t have to constantly empty the bucket and it will also manage to absorb great amounts of moisture from the air.

  • Can cover large areas

    Being bigger and more powerful means that it is suitable for large areas like basements, garages, workshops, or stores. The high capacity enables it to circulate more air and cover a larger space than normal size models so you will only need one device for a large room.

  • Great for intense humidity

    If you are dealing with excessive humidity, a small humidity reducing device would not be powerful enough to draw all the moisture from the air. Therefore, the industrial type is the most appropriate for use in houses with severe humidity issues.


  • A higher price

    Industrial-grade models cost a few hundreds of dollars so the investment is not to be overlooked. Compared to smaller size models that can be used in different rooms of your house, these ones can cost up to 10 times more, which is why many prefer to use multiple smaller models.

  • More space required

    The size is another drawback especially if you need to place it in a crowded basement or in a garage. The housing can reach even 40 inches and they also weigh a lot so moving it or carrying it is not the simplest thing to do. As such, if space is not too generous, you might have trouble fitting a bulky dehumidifier.

  • More energy-consuming

    A large power also means a higher energy consumption, which leads us to the biggest downside many customers complain about. Aside from the initial cost, you will also notice an increase in the electricity bill, especially if you will have it turned on almost the entire day.


Rating Our Selections

Needless to say, there are certain parameters you must follow when comparing products in this niche, parameters that we will talk about in the following. Stats like dehumidification capacity, area coverage, and convenience enhancing features, among others, are what make a moisture removal system of a better or lesser quality.

Rating Criteria How Product Quality Is Influenced Product to Receive the Best Score
Moisture extraction capacity This spec indicates the amount of moisture the dehumidification device is able to remove from the air over the course of an entire day. It is the best indicator of its performance efficiency as it shows how fast the system is in lowering humidity levels indoors, which is the precise reason why you bought it to begin with. The higher the capacity the better, obviously, as even in highly humid spaces, it will effectively and rapidly normalize environmental conditions. Dri-Eaz LGR 7000XLi
Area coverage When you buy the system, you intend to use it in a specific area with high humidity issues. What is important is for you to know the size of that specific area before you browse for your ideal system to avoid buying an over or under performing product. All devices have the area they cover listen in their spec sheets, and you can compare the area coverage you need it to provide to the stat which appears on the sheet to make sure you are making a proper purchase. What we recommend is for you to go a bit higher than you actually need as an over performing system is never a bad acquisition – you never know when you will need to use it somewhere else, and it’s best to be covered in any situation. Dri-Eaz F413 Revolution LGR
Automatic defrost A good functioning of the system in all environmental conditions is what you need, but this cannot be provided without the presence of the automatic defrost feature. The role it plays is to ensure ice won’t build up on the coils and other internal parts of the device when it is placed in a low temperature space. Thus, this is a lifespan prolonging feature that you cannot afford to overlook if you want to make a quality, lasting acquisition. Aprilaire 1850F, Dri-Eaz LGR 7000XLi, PerfectAire 1PACD150 Damp2Dry, Maxxair DH 065 BLU, Ideal-Air 700836
Timer This is a power consumption reducing feature that is preferable for the system to come with as, in addition to lowering costs as it allows you to limit the device’s operation, it enables you to truly fully customize its operation. Basically, you will be able to set the device to run for as long as you consider it to be necessary without actually turning it off yourself as it will do so on its own after the period of time you have set passes. PerfectAire 1PACD150 Damp2Dry
Air filter The presence of an air filtration media enhances the system’s operational effectiveness as it ensures that, in addition to lowering indoor humidity, it will clean the air of impurities and airborne particles. Thus, you will breathe in air that is truly clean and safe for your health.

As it can effortlessly handle removing excess moisture in an area of up to 7000 square feet, the Dri-Eaz F413 Revolution LGR is perfectly suited for industrial, heavy-duty dehumidifying purposes. Sure, it does cost a pretty penny, but considering the advantages it brings to the table, like its 80-pint moisture removal capacity per day, or the lifetime warranty provided for the housing, we can confidently state that it is worth every cent.

However, as great as the aforementioned model might be, for those battling with extreme excess humidity, the right pick is definitely the Dri-Eaz F203-A 1200 18-Gallon that can remove up to 145 pints of moisture over a 24-hour time period. Furthermore, it can handle operating in extremely low-temperature conditions of 33 degrees Fahrenheit, so you can rely on it in basically any environment, as harsh as it may be.

What humidity level should be maintained in a building?

For the protection of the building’s structure as well as for the well-being of its inhabitants, a relative humidity of 45 to 50 percent should be kept. Alas, modern buildings are constructed to prevent the cold from entering, this sealed design making the environment inside them a lot damper. Thus, without the addition of a dehumidifying appliance like the ones shown in this article, commercial models which can take on humidity issues in extremely large spaces, there will never be normal a normal humidity level inside the building.

What is the ideal placement for the dehumidifying appliance?

Seeing how it is supposed to control a vast area – a greenhouse or an entire building – it should be left in a position where it has the most exposure. For example, if you put it in a building, place the appliance in a hall which connects multiple rooms to each other. This way, it will equally work on lowering indoor humidity inside the entire building instead of focusing on a sole area more than on the rest.

Is it a necessity in a greenhouse?

Yes, seeing how plants of all kinds are very pretentious when it comes to the environment they are placed in, it is mandatory to preserve a normal humidity level inside the greenhouse. Otherwise, all of your efforts to grow and breed the plants will be in vain as they will wilt, humidity, temperature, and light being the three elements that affect the well-being of plants the most.

Are commercial units louder than residential ones?

When compared to residential units, commercial dehumidification appliances do indeed tend to be louder in their performance. However, this is not to say that all commercial dehumidifiers are bothersome when it comes to their noise output. As you can see, the DRI-EAZ F203-A 1200 produces a decent 34 dB noise output – thus, it is extremely quiet when it operates, not presenting a distraction regardless of where you store it.

Does it cost a lot to run this appliance?

As opposed to a residential unit, yes, a commercial dehumidifying appliance does cost more to run. This is a result of its superior moisture extraction capability, being designed for heavy-duty tasks, not the normal extraction of excess humidity in a small area like the room of a house. However, you can find energy efficient dehumidifying devices even amongst the commercial category. Just compare energy consumption between different models and find the one that suits your needs best.

    I have the Aprilaire 1850F in my 4000 sq.ft. basement that includes a gym, a laundry room, and a storage room separated by walls and it works great. We were skeptical at first about spending so much on a dehumidifier but we are now very pleased with how it deals with constant humidity issues. Would gladly recommend it.
