Just like our homes, commercial spaces are prone to mold problems. This often occurs when trapped moisture is left unchecked – from leaking pipes, faulty air conditioners, rainwater leaks, and more. If your business space is dealing with this problem, the best commercial dehumidifiers will be a big help.
Of course, it’s important to note that diagnosis comes first before the solution. Dehumidifiers will only do their job once you find the source of excess moisture. This way, you can also perform additional measures that will prevent excessive moisture from wreaking havoc in your commercial space.
Unlike residential or portable types, commercial dehumidifiers have a bigger capacity. This allows for fast and efficient dehumidification. Below, I reviewed 8 of the trusted dehumidifiers in the market.

Value For Money
Aside from that, this unit uses a desiccant method. There’s no need to empty water tanks and you don’t have to worry about the risk of overflowing. Even though it’s not a refrigerant type, this dehumidifier packs optimal airflow. It’s also reasonably quiet for just 58 dB. The only downside I see here is that desiccant types need an outdoor vent to funnel the moisture away from your building. This may not always come in handy for all commercial spaces.

The good thing here is that your entire commercial space will have controlled humidity levels all year long. For many, this is much better than using multiple portable types.
BlueDri BD-130P 225PD Commercial Dehumidifier
If you’re looking for another portable dehumidifier, you should consider the BlueDri BD-130P. This unit can remove up to 225 pints of moisture from the air per day.

Overall, this is a great pick, but I hope they can make the wheels sturdier. This way, it won’t be prone to bending.
How to choose the best commercial dehumidifiers
If you’re in the market for a commercial dehumidifier, it’s important to consider the following aspects first:
✔️Portable vs. integrated
When getting a commercial dehumidifier, the first thing you should consider is whether you need a portable or integrated model. This will impact the unit’s ease of use, coverage, and installation requirements. Here are the differences between the two:
- Portable dehumidifiers. Portable doesn’t always mean small in terms of capacity. Many portable dehumidifiers can cover as much as 5,000 sq. ft. The good thing here is that portable dehumidifiers don’t need special installation and can be moved around your commercial space anytime. However, it requires regular draining and has capacity limitations.
- Integrated dehumidifiers. This type of dehumidifier is also called duct-able because it’s installed right into the HVAC system of the property. It offers a whole-house function since it extracts moisture with the help of the other air system components. While integrated dehumidifiers require professional installation and maintenance, it’s more convenient for very large spaces prone to moisture.
Another thing you should consider is the drying method of the dehumidifier. The most common options in the market are heat, refrigeration, and desiccant methods. Below is the rundown of these types:
- Heat. Dehumidifiers that use heat to dry the moisture in the air are often used in an industrial setting. Basically, it increases the air temperature to evaporate the moisture. This is effective, but the commercial space must be unoccupied, and the excess heat may damage appliances and similar items.
- Refrigeration. Dehumidifiers that use refrigeration are the most common option in the market. It works like air conditioners, which utilize refrigerants to extract moisture from the air. This allows users to run the dehumidifier even with people inside the building.
- Desiccant. This method propels the humid air into an absorbent material. Through this, the moisture will be collected. This can be used in large spaces as an alternative to refrigerant types.
The coverage area of the dehumidifier is the most crucial feature you should check. This will dictate how efficient the unit will be in removing excess moisture from your commercial space.
For efficient functions, the dehumidifier should be sized based on the floor area of the place where it’s going to be used.
The good thing is that manufacturers always indicate a maximum floor area coverage on the dehumidifiers they produce. This makes it easy for buyers to identify how many dehumidifiers they need for a specific room.
However, if your commercial space is extremely damp, you should consider getting a much bigger dehumidifier than the standard recommended capacity. This way, the unit can keep up with the very high humidity levels.
Concerning the coverage area, you should also consider the tank capacity of the dehumidifier you will get.
Commercial dehumidifiers are often available in at least 10-pint models. One of the biggest units I’ve seen can remove up to 200 pints of moisture from the air.
However, it’s important to understand that commercial dehumidifiers are often in a continuous drain setting. If we are to consider the tank size alone, it would be around 10 to 20 pints, so multiple draining is necessary.
Also, many commercial dehumidifiers don’t use tanks. Instead, they are equipped with pumps, so the collected water is drained right away to your sink or somewhere else.
Speaking of draining, commercial dehumidifiers can either be using a built-in water reservoir/tank or a continuous drain. Most of the time, it would be the latter.
Continuous draining allows you to run the unit for long hours. Also, you no longer have to worry about overflowing since the water isn’t collected inside the machine.
However, the good thing is that many dehumidifiers have dual drain options. You can use them in a continuous drain or utilize the tank inside.
Take note that each dehumidifier has an ideal operating temperature range. This means that the unit will only be efficient when used within a specific temperature.
It’s typically equipped with an auto-defrost feature to avoid icicles from forming. For example, most dehumidifiers in the market won’t run when used in temperatures lower than 60F. Meanwhile, there are models explicitly made for low-temperature conditions.
The dehumidifier of your choice must have a built-in humidistat. This is a non-negotiable feature to ensure that the unit isn’t drying the air too much.
Aside from that, it will allow you to set a specific humidity target. Once it’s achieved, the dehumidifier will shut down or engage automatically.
This will also serve as a safety feature so that the dehumidifier won’t overheat or overflow.
Take note that commercial dehumidifiers will be noisier than compact types. This is due to the higher capacity, larger motor, and higher airflow. It’s a trade-off if you want efficient dehumidification.
If noise is an issue, you’re better off using an integrated dehumidifier. This model is tucked away from the usable space of your building.
