From its compact design to its fantastic energy efficiency, this model is faultless from all points of view, and it is particularly suitable for large spaces and buildings where excess moisture is an issue.

The F412 is also super-efficient when it comes to moisture extraction, as it boasts a daily extraction rate of 80 pints, which makes it an ideal choice for a highly moist area.

One of the main advantages is the fact that this unit is capable of performing in extremely cold temperatures. Specifically put, it is capable of withstanding temperatures going from 33 to 100 degrees Fahrenheit. However, this dehumidifier comes with no wheels, which is really depressive considering its size. Consequently, movability can be a bit difficult, especially when you need to move it rapidly. Use a handtruck in case you need to transport it from one place to another. The dehumidifier’s design offers you to place one unit on another for even easier transportation.

Apart from that, it can also cover about 2,300 square feet, which is suitable for construction sites and office buildings.

The machine also comes with semi-pneumatic wheels so that you can easily and conveniently move it from one place to another. Besides, the smart design it sports will reduce shaking and shock triggered by the moving machine – making it ideal for uneven surfaces.

The next product on our list is the Active Air 100-Pint Commercial Dehumidifier. We have included this model specifically due to its higher humidity extraction capabilities and its extreme ruggedness. With its ability to extract up to 100 pints per day, its heavy-duty compressor, and the durable, heavy-duty powder-coated metal casing, none of our reasons for picking this model can be said to be unreasonable. However, considering it has a coverage area of only 861 square feet, this unit is probably the model with the smallest coverage area on our list.

What’s more, the appliance also comes with an automatic restart feature, which allows for use with humidistat controllers. The removable filter also allows for easy cleaning and maintenance.

Buying Guide

Commercial and home dehumidifiers work quite similarly, only that a lot more is demanded from commercial models since industrial spaces are usually larger and require a more intense and constant operation. The guide below will help you choose the right commercial unit for your needs.

Features to consider while choosing a commercial dehumidifier

As we have already mentioned earlier, there are many factors to think about when choosing the right commercial dehumidifier for your office or business. Below are some of the most vital features that you must consider.

Coverage area

The measure of space that can be covered by the dehumidifier has an enormous expanse. These machines can cover areas as large as 10000 cubic feet and above.

This is vital since the sum of energy needed to run your appliance will differ considerably based on the energy efficiency of the product and the amount of space it needs to cover. Keep in mind that this rating can significantly vary between various brands and even different models within the same brand.

A dehumidifier with one of the most impressive coverage areas on our list is the Dri-Eaz F413 Revolution LGR Dehumidifier which is suitable for spaces of up to 7,000 square feet.

Dehumidification performance

If your office or business is large in space, you will most likely require a model with a 70-pint daily dehumidification rate at least. It’s essential to know exactly what you need before making your purchase. With the 142 pints per day, the Perfect Aire 1PACD150 Damp2Dry Commercial Dehumidifier has the highest dehumidification rate on our list.

Pump

It’s important to buy a commercial unit with a built-in pump for increased convenience. A built-in pump pushes the collected water automatically through a hose attached to a sink or a drainage hole somewhere around. Since they’re automatic, the moisture can be vertically pumped out. Considering their usual large sizes and heavy weights, it’s practically unreasonable to buy a commercial dehumidifier that doesn’t have a built-in pump as you would have to be emptying the water container manually. Thankfully, each product on this list comes with an inbuilt pump.

Noise level

Nobody likes noisy appliances. Averagely, most models out there rate 50 decibels and more. At higher levels it can be rather disruptive and irritating, especially during meetings or at night. We recommend you to purchase a model that boasts two-speed fans, which will guarantee smooth and quiet operation regardless of the level of humidity. Quiet units are energy efficient as well.

Test the noise level of an appliance to verify its decibel spec before you buy it.

Handles and wheels

Best Commercial Dehumidifier
If you choose a bulky and heavy commercial dehumidifier, think about going for one that has caster wheels. Machines with caster wheels can be moved quickly from one room to the next whenever it’s needed. Additionally, look for units that have handles as they allow for improved portability. Models that boast both handles and wheels are XPOWER XD-125 Industrial Commercial Dehumidifier, Active Air Commercial Dehumidifier 100 Pint 2018 Model, BlueDri BD-76-RED Commercial Dehumidifier, and Dri-Eaz LGR 7000XLi Portable Refrigerant Dehumidifier.

Warranty

Buying an electronic appliance without a warranty is like jumping off a plane without a parachute. While both cases may not be evenly fatal, they are still somewhat comparable. When looking to buy the right commercial dehumidifier for your office or business, one of the first things you must consider is the warranty offered along with the product. That way, you will be able to sleep peacefully knowing that the company will be there to provide you with a solution should anything go wrong with your unit within the stipulated period of time.

Extra features

You might also have to consider some useful additional features such as a defrost system and inbuilt humidistat. The defrost system is particularly useful as it allows the machine to be used in extremely cold temperatures by automatically clearing any ice build-up on the coil. Also, check the quality of the housing and the material with which it is made, and consider if the package includes hoses and cords as you don’t want to be spending extra money on accessories.

Tips on how to get a commercial dehumidifier work for many years to come

Place your dehumidifier strategically

Best Commercial DehumidifierPlacing your unit in a region where there will be an efficient air circulation is one of the secrets to maintaining a commercial dehumidifier. Keep the unit at least six inches away from the wall so that nothing will block its air intake and exhaust. These machines are most efficient with a room temperature of 65°F at least; the motor can be burnt or frozen by extreme temperatures except it’s a unit specifically designed for an extremely low or high temperature.

Adjust your room’s humidity level

Apart from the temperature of the room, another factor that determines the lifespan and efficiency of a dehumidifying machine is the room’s humidity level. These machines are most effective when used in 40 to 50 % humidity range. The humidity level can be controlled by making adjustments on the humidistat, which is a machine that helps monitor and maintain a preferred level of humidity in a room. Some models like the Dri-Eaz F413 come with an inbuilt humidistat.

Clean or replace the filter

Dehumidifiers typically come with a filter that helps to remove dust, allergens, and other unsafe particles from the atmosphere. The filter serves as a protection to the unit and its components from unwelcome elements and also helps create a cleaner, healthier, and more comfortable indoor air. Every model comes with a guide that says a recommended period after which its filter will have to be changed. Some filters can be regularly cleaned instead. Adhere to the recommendations consistently so you will enjoy your unit for many years to come.

Clean the coils of the dehumidifier

The coils of these machines have a tendency of causing freezes whenever a lot of dust is stuck in them. In fact, this may consequently damage your unit if adequate care is not taken. In order to prevent this from happening, you must clean and vacuum the coils of your dehumidifying appliance on a regular basis.

Check the coils for frost

Best Commercial DehumidifierSometimes, ice may build up in your dehumidifier if it has been running in a very cool temperature. Consequently, the daily efficiency of the machine may be affected by this, and may even cause permanent damage to the appliance. If you have a feeling that ice is accumulating in the unit’s coils, try to check the coils for frost as soon as you’ve turned it off. In some units, checking the internal coils is not possible, so you will have to contact the manufacturer to get the coils checked.

Follow the instructions and troubleshooting tips provided in the manual. Some models such as the AlorAir Commercial Water Damage Restoration Dehumidifier and the Active Air 100-Pint Commercial Dehumidifier feature automatic defrost system. The unit automatically detects frosts and turns its compressor off while allowing the fan to run so that the built-up ice can melt. Within a very short time, the appliance is back running normally.

Regularly clean the water container

Only emptying your machine’s container or utilizing soap doesn’t guarantee a clean water container. In fact, employing a disinfectant in cleaning the water tank can cause a layer of yeast and germ deposit at the base of the container. As a consequence, the accumulated debris could end up infecting the indoor atmosphere and lead to a host of respiratory issues. To prevent a potential health hazard like that, monitor the container regularly to make sure it is always free of germ. Again, adhere to the recommendations provided in the manual to perfectly understand the most effective techniques to use in cleaning the tank of a particular model.

Never turn on the machine instantly after turning it off

Just like all electronic appliances, wait for ten minutes at least to turn the unit on again after turning it off. It’s vital to maintain this time gap as it allows the machine some time to even out the pressure that was manufactured when the machine was operating. Apart from allowing the appliance lesser time to eliminate humidity effectively, turning the unit on instantly after turning it off can also cause damage to its compressor. Due to this reason, in particular, some models have a delayed-start feature that protects the appliance by preventing the occurrence of short-cycling.

FAQ

Since you have to be maintaining it on a regular basis, then commercial dehumidifiers are not “install-and-forget-it” units. Let’s not forget that most of them are either battery-operated or power-operated, which means you must be either connecting them to a power source or replacing their batteries consistently. Besides, you also need to be cleaning and replacing their filters as at when needed.

Since most hotels, supermarkets, and nightclubs focus on dehumidification and not temperature control only, the optimal humidity level that should be maintained in those places is between 40 and 45 percent.

Ice can build up on the evaporator coils of a refrigeration dehumidifier under some humidity and temperature conditions. The ice accumulation can hinder air circulation and eventually create a block covering the coils. The accumulation prevents the machine from running effectively and optimally, and can even end up causing damage to the unit. In severe cases, the accumulated ice can distort or deform mechanical elements, thereby permanently damaging the machine.

High-quality dehumidifiers usually come with a defrost system. This system will turn the machine off and enable the ice-covered evaporator coils to defrost. As soon as the coils have been defrosted, the unit will restart automatically.

Our Verdict

Owing to its super large coverage area and a host of advanced features incorporated into it, the Dri-Eaz F413 Revolution Dehumidifier is our clear winner of this round. Apart from being useful for commercial places, people with large homes can also employ the service of this powerful machine, thanks to its versatility.

Our second choice is the AlorAir Commercial Water Damage Restoration Dehumidifier, which is a machine in which we have found almost no flaw whatsoever. Covering a relatively large area and being sold at a reasonable price, coupled with the hot gas defrosting system built into it, it’s very hard to fault this machine.

Our third pick and our choice for the model with the easiest operation is the Perfect Aire 1PACD150 Damp2Dry Commercial Dehumidifier. With the included semi-pneumatic wheels and digital control pad, this machine is indeed effortless and convenient to use.
