How Do Commercial Dehumidifiers Compare to Other Models?

As the name states, commercial dehumidifiers are meant for commercial use. You can see them operating in offices, shops, warehouses, spas, etc. Compared to dehumidifiers intended for homes, commercial units are generally more powerful and even bulkier in size.

This list we have created showcases a number of commercial dehumidifiers. You will get to see how they differ from other (household) models in terms of size and the amount of moisture they eliminate.  

AlorAir Dehumidifier 85 Pint

Commercial dehumidifiers also typically offer more area coverage compared to household units. Furthermore, commercial units can lower humidity levels to below 30%, especially when it comes to models meant for quickly dealing with water damage due to heavy rainfall or floods.

They also tend to have a Hot Gas Bypass System which enables them to continue operating in lower temperatures. Such a feature is very useful when a dehumidifier is being used in spaces with lower temperatures, like warehouses, for example.

Aspects to Consider Before Buying

Before you go ahead and buy the first commercial dehumidifier you see in the market, you need to do your research. Not all dehumidifiers will be able to cater to your needs. So, here are some aspects to consider before buying a commercial dehumidifier.

Area of Coverage

You need a dehumidifier that is perfect for the amount of space you have. That is why it is vital you check the area of coverage being offered by a commercial dehumidifier before you purchase it. Some models are able to cover spaces up to 10000 cubic feet. Some can go even higher. Buying a unit that isn't able to handle the commercial space you have won't do anyone any good. So, measure the space you have and then compare it to what a dehumidifier can offer.

Built-In Pump

We recommended that you opt for a unit with a built-in pump. Such a model will increase the overall convenience. A built-in pump can automatically expel collected water (via a hose). Such a pump does away with the need for you to manually drain the water container when full.

Noise Level

Noisy machines can quickly grow annoying. You don’t want a noisy dehumidifier distracting you during businesses meetings, right? Always check the noise level of a unit before buying one. A model producing noise near 50 decibels or lower is recommended.


Buying a portable dehumidifier is a bonus. There are models with handles and wheels, allowing you to place them anywhere you want with ease.

XPOWER XD-125 has wheels for easy transport from one place to another.


Go for a unit which offers a reliable warranty. With a warranty, you know the company that created the dehumidifier has your back if an issue arises.

Auto Restart

A dehumidifier with an auto restart feature is great if your business is in an area that faces power failures. Such a unit will restart on its own when the power comes back.

Built-In Humidistat

Having a built-in humidistat means the unit will provide you real-time humidity and temperature readings.

Low-Temperature Operation

Warehouses tend to have low temperatures, especially during winter. So, if you work in such a space, opt for a dehumidifier that can operate effectively in low temperatures.

That is why we had to add our best Honeywell selection to this list. Not only is this is an Energy Star certified unit, it happens to be one of the most energy-efficient units out there.

The design of this model is compact, meaning you can place it in cramped spaces if need be. It has been built to operate through the ducting of an area's air-conditioning or ventilation system.

Types of Commercial Dehumidifiers

While we are on the topic of commercial dehumidifiers, it is a good idea to know about the various types of commercial dehumidifiers you might come across.

In short, as far as working is concerned, these are classified as the ‘Desiccant Type' or the ‘Refrigerant Type.' When it comes to usage, we have the ‘Portable Type' and the ‘Industrial-Type.'

Portable Dehumidifier

A portable unit, as the name states, can be easily moved around. These are generally made for office use. The design is also normally appealing. They also have fan speeds and control panels.

Industrial Dehumidifier

These dehumidifiers intended for industrial use; while they can be portable, they are typically fitted on walls or the floor. They are quite bulky in design.

Pool Dehumidifier

Such units are used in spaces with heated indoor pools or Jacuzzis. You might even see them in spas.

Refrigerant Dehumidifier

Refrigerant dehumidifiers are also known as condensation or mechanical dehumidifiers. They make use of the refrigeration cycle to reduce an area’s humidity levels. They have a fan which pulls in humid air to the evaporator. The captured air is then chilled to condense into water. The resulting water is collected in a tank.

Desiccant Dehumidifier

Such models have a rotating desiccant wheel. The fan brings the air to the wheel, and dry air is released. Dry air passes through the system to keep the wheel from remaining wet.

How to Clean a Commercial Dehumidifier

Knowing how to maintain your commercial dehumidifier properly is essential if you want it to remain working effectively down the line. Due to how these models work, they collect mold, bacteria, dust, and other particulates from the air. You should consider cleaning a dehumidifier at least twice a month, primarily if it is used frequently.

Many of the dehumidifiers mentioned in our review list have the same mechanism. So, following the steps below should enable you to clean a unit properly.

  1. Unplug the unit: To clean your dehumidifier, the first thing you will need to do is unplug the unit (after turning it Off).

  2. Clean the exterior: You should clean the outside of the dehumidifier while you’re at it. Using cleaning solvents isn’t recommended.

  3. Clean out the reservoir: Even though a built-in pump does drain water, the collecting tank can get dirty. So, clean it up.

  4. Rinse the air filter: The air filter being used is a vital part of a dehumidifier. The filter will collect mold, dust, and other nasty stuff. After taking out the filter, wash it gently with soapy water and a sponge. Remember to let the filter dry before reinstalling it.

Cleaning Tips

  • After opening the dehumidifier, using a vacuum to clean the insides is a good idea. You can also use a vacuum to clean the air filter.
  • Ensure that dust or debris isn’t being collected on the coils of the dehumidifier.
  • You should always consult the manual before beginning the cleaning process.

Do make sure to check out this informative video to see the cleaning process and the importance of keeping the air filter and coils as clean as possible.


Buying a reliable commercial dehumidifier is a great way to ensure your workplace has the humidity levels you prefer. Moreover, such a unit is able to protect spaces from mold growth and other humidity-related issues.

We hope our Best Commercial Dehumidifier Review list helps you to make an informed decision. Go ahead and check out the models we recommended to see which works best for you.

People Also Ask

Before we let you go, we would like to answer a few frequently asked questions pertaining to commercial dehumidifiers.

What is the Optimal Humidity Level that Should Be Maintained in a Hotel, Supermarket, and Other Commercial Places?

If you ask us, we would advise you to maintain humidity levels below 60%. We say this because lower than 60% helps prevent mold growth and mildew spawning. Furthermore, lowering it below 50% can aid with preventing dust mite proliferation. Unless a commercial space has water damage that needs to be quickly dealt with, there’s no reason for you to go lower than 40% or 30%.  

Can I Use a Commercial or Industrial Dehumidifier in My Home?

You certainly can use a commercial or industrial dehumidifier in your house. The models we have mentioned in our review list can easily be used at home. The humidistat featuring units will ensure the preferred humidity levels are maintained in your house. However, do keep in mind most commercial models aren’t the most visually appealing. So, they might not always go well with your home décor.

How Much Water Will a Commercial Dehumidifier Remove?

The answer to this question depends on the Commercial Dehumidifier model you opt for. There are units which are able to remove 55 pints of water while others remove 160 pints a day. It all depends on how much moisture you want to be removed and how quickly you want it to be gone from a space.
