Commercial Dehumidifiers

Commercial or industrial dehumidifiers 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 dehumidifiers, they offer great results when it comes to capturing moisture and providing a healthy work environment. Now let’s see which are the commercial dehumidifiers worth investing in.

Ideal-Air 700836

A commercial grade dehumidifier must be a heavy-duty model made to last and to operate in hard conditions. The 700836 is one of those dehumidifiers that can run around the clock and still provide the highest performance. It is encased in a metal housing coated in powder to prevent rust and to ensure durability in humid areas. On top of it, you will find a digital control panel with a display that shows readings of the humidity and temperature levels.

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

Not the best looking dehumidifier out there, but certainly one of the best when it comes to its performance, this Ideal-Air unit is 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

The dehumidifiers designed for commercial use are stronger and more durable than other dehumidifiers 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 a commercial device can help eliminate high relative humidity levels, saving time, money and energy cost at the same time. Furthermore, this type of dehumidifier 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, the commercial units 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 size when purchasing the device.

Commercial or Residential Dehumidifier – Which one to Pick?

As the name itself suggests, this type of dehumidifier is designed for commercial 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 the commercial and the residential dehumidifiers 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 a commercial model that is more powerful than a residential one.
  • However, not every large room needs a commercial model because there are also bigger residential dehumidifiers 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 dehumidifiers 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 a commercial model with auto shut-off, automatic pump-out, and a built-in thermostat.


Major Pros and Cons

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


  • The large absorption capacity
  • By far, the biggest pro of owning a commercial dehumidifier 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 industrial dehumidifier for a large room.

  • Great for intense humidity
  • If you are dealing with excessive humidity, a small dehumidifier 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
  • Commercial-grade models cost a few hundreds of dollars so the investment is not to be overlooked. Compared to smaller size dehumidifiers 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 than buying a large commercial model.

  • 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.


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 dehumidifier 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. Another entry noteworthy at the final of this article is the Ideal-Air 700836 that, despite the unimpressive warranty, manages to make up with its performance – it removes up to 100 pints of moisture per day, and it provides an optimal operation in large areas.



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 the dehumidifier 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 dehumidifiers?

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.

      This is, indeed, a more expensive model, but its performance makes up for the investment. Plus, it prevents further damage in the construction of your house, so you will be saving even more money.
