The best commercial dehumidifier comes with rugged construction, lots of features, and the ability to dehumidify large spaces. Many have stackable designs for use in tandem with more than one unit for even larger rooms.

If you’ve got a huge warehouse or other large space to dehumidify, don’t go mucking around with dehumidifiers that look like plug-in air fresheners. Go for the big commercial beasts that can suck the water out of the air before you get back from your lunch break.

Industrial grade dehumidifiers also come in handy if you have a large basement or other space that you need to keep dry and protect from moisture. While we will focus on units made for commercial use, keep in mind some are very versatile and could be used for personal or residential projects.

There are a lot of commercial dehumidifiers on the market, so it can be overwhelming when you start looking. We’re here to filter through the noise and review some of the best options so you don’t have to waste your time.

First, Some Vocabulary

As you look at these commercial dehumidifier reviews, you’ll notice a lot of abbreviations for measurements to compare the capacity and power of the different units. Here are some acronyms and other terms you’ll see so you don’t get lost in an alphabet soup.

CFM stands for cubic feet per minute. It measures the amount of air the unit can process every minute. A similar measure, CMH (or cubic meters per hour), also measures airflow, just on a slightly larger scale.

AHAM stands for the Association of Home Appliance Manufacturers. The number you’ll see next to it measures a dehumidifier’s performance at a standard testing conditions of 60% humidity and 80°F. It’s measured in pints per day (PPD) of moisture removed from the air.

Similarly, the saturation number measures a dehumidifier’s PPD in the most extreme of environments: 90% humidity and 90°F. That’s the absolute maximum that the unit can handle. However, unless you live in a swamp, AHAM is usually the more relevant statistic.

The humidistat is an instrument in some dehumidifiers that controls the relative humidity of the air. In some cases, you can use this to set your desired humidity level, and the machine will automatically activate or deactivate based on this level.

HVAC stands for heating, ventilation, and air conditioning. It’s a term that also includes dehumidifiers. Some dehumidifiers connect to your HVAC system for enhanced operation.

Picks for the Best Commercial Dehumidifier: A Buyer’s Guide

We’ve reviewed ten of the best commercial dehumidifiers that we think are the best options, so keep reading to determine which is right for you.

Best Waterproof Commercial Dehumidifier: AlorAir LGR 85 Pint with Pump

Perhaps the best feature included in the AlorAir LGR 85-pint commercial dehumidifier is the fact that it’s waterproof. It is designed with flood damage restoration in mind. You can completely submerge the unit because a rubber strip seals the circuit board and protects it from water.

This efficient unit has low temperature operation for better energy consumption or high temperature operation for more effective drying when you need maximum water damage restoration. It’s easily stackable if you need to use more than one unit at a time.

HGV defrosting means you get a system that will quickly and efficiently remove ice from its own coils, protecting them and making your unit last longer. These epoxy-coated coils also maintain their heat transfer ability well.

The compact design is also space-saving, while the heavy-duty handles make for easy lifting. Don’t let its size fool you; it comes packed with features like auto on and off, rigid handles for carrying, a removable and washable MERV 8 filter, and built-in storage for the cord and hose.

The bright LED screen displays temperature and humidity levels at both outlet and inlet while allowing you to see GPP and operating settings at a glance.

The unit’s pump has a 20-foot lifting distance, so it can quickly move water up and out in the case of extreme moisture.

Best Heavy Duty Dehumidifier: Dri-Eaz LGR 3500i with Pump

The Dri-Eaz LGR 3500i commercial dehumidifier supercharges your dehumidification with a rugged and durable design that’s great for heavy-duty use. It’s large and heavy, but the rolling wheels make moving it much easier.

Delivering up to 264 pints of moisture per day of water removal at saturation level, this beast of a dehumidifier can take care of all of your moisture problems in even the largest of spaces.

The automatic humidistat control allows the unit to turn itself on and off as needed and adjust speed to remove moisture according to your custom humidity levels.

The digital control panel can display four different languages and will show you specific system messages instead of error codes. This makes it easy to troubleshoot problems and fix them quickly. The display also shows the inlet and outlet temperatures, settings, and sensor readings.

The roto-molded housing design is easy to maintain and won’t damage your floors. It’s designed with tough corners for leak resistance and long life.

A 40-foot hose ensures you can drain water properly, even across longer distances, while the 25-foot power cord allows you to reach an outlet across the room.

This unit works with Dri-Eaz ducting so you can target and control your drying efficiency and air circulation for better performance. It also features a 33°F to 100°F temperature range for operation in both warm and cool weather.

Features like a defrost mode keep the coils from freezing and turn any frost back into water for removal from the air and the unit. This keeps your coils operating efficiently and helps the unit last longer.

The six-year warranty covers the coils and condenser, the one-year warranty covers parts and labor, and the lifetime limited warranty covers the housing.

Product Details and Specifications

Best Commercial Dehumidifier for Basements: Inofia 232 PPD

The Inofia CFT 4.0D industrial dehumidifier offers power at a reasonable price. The humidistat will automatically regulate humidity levels for you, and you can register the unit’s progress on the easy-to-read LCD screen.

This dehumidifier is constructed for portability, featuring two front caster wheels and two back semi-pneumatic wheels that make it easier to tote around than your average piece of carry-on luggage.

What separates the Inofia from other commercial dehumidifiers is its extremely high capacity. It can process greater volumes of air and remove more pints of moisture per day than any other dehumidifier on our list. The drawback is the smaller space that it can cover: a mere 8,000 ft².

Although this appliance doesn’t have a pump, it does feature continuous drainage, and it comes with a drain hose. It can bring the humidity of an area down to as low as 10%, though you probably won’t need to set it much lower than 30%.

The Inofia’s automatic error detection system is handy, though you’ll need to look up the displayed error codes in the manual. The filter is washable, which means you won’t need to run out and buy a new one every few months.

Inofia offers a full one-year warranty as well as a 60-day money-back guarantee. If you find that the device isn’t working as promised, you can send it back any time in the first two months.

Product Details and Specifications

• Suited for spaces up to: 8,000 square feet
• Max airflow: 647 CFM/1100 CMH

Best Commercial Dehumidifier for Targeted Drying: Dri-Eaz DrizAir 1200 with Pump

It can process air at a rate of 227 cubic ft per minute for efficient water removal, and the pump basin has a 40-foot hose for draining excess water across large spaces.

Unfortunately, the pump isn’t strong enough to lift water, so you’ll need access to a drainage source in the floor. However, continuous emptying means you don’t have to manually dump the basin as long as you have access to a drain.

The unit’s display panel can be adjusted to English, French, Spanish, and German for ease of use. These controls are digital for easy reading, setup, and adjustments to operation.

The duct attachment allows use with the Dri-Eaz layflat ducting to target control of your air circulation for more efficient drying. The 25-foot power cord and housing on wheels allows you to roll it throughout your space for targeted use.

The roto-molded housing ensures strong corners and damage and leak resistance. These models are compact and stackable, meaning if you need more than one for your large space, you can store them efficiently when they’re not in use.

With up to 180 cubic ft per minute of air flow, you can remove water from your space. However, this is not quite as efficient as some of the larger units on the market. This is a unit you would need operating in the background all the time to continuously achieve appropriate humidity levels.

However, if you do keep it running all the time, the dehumidification will automatically kick on when the humidity climbs above your desired level and then shut off again to preserve energy. It can operate at full throttle or lower speed as needed.

There is no water tank to dump, meaning you’ll need somewhere to drain the water, but it works efficiently to remove moisture from the air and drain consistently without pooling. It has a display for easy operation, a long power cord, and a reusable filter.

With the ability to operate from 33°F to 100°F, your unit can power up for dehumidification as needed to maintain the correct humidity or clean up after excess water.

It has two drying modes. You can dehumidify your space or dry clothing by switching modes. Targeted heat and blown air will provide an environment that allows your clothes to fully dry without damage from a clothes dryer.

The LED intelligent controls show your target humidity and the current humidity level. Change the fan speed, auto defrost your unit in cold temperatures, and set a two- or four-hour sleep timer.

The automatic shut off feature will kick in when the water tank is full, and the alarm will warn you that it needs to be emptied. The 4.5-liter tank is large enough for expansive spaces or excess moisture problems.

It can also be equipped with continuous draining so you don’t have to worry about the water tank capacity. Just set it up to drain through the 3.2-foot hose, or order a longer hose if you need to stretch it farther.

People Also Ask

No one expects you to be an expert on dehumidification technology. Here are some of the more frequently asked questions concerning commercial dehumidifiers.

What is the Best Industrial Dehumidifier?

The most powerful commercial grade dehumidifier in this review, the Dri-Eaz LGR 3500i, is an excellent choice that is built to last. However, that power comes at a price, and if you don’t have 30,000 square feet of space to dry, you may be overpaying.

It depends entirely on what you’re looking for, how big your space is, what features you need, and your budget. As you can see, there are a variety of options, and this list is not exhaustive. There are plenty more.

Compact designs are great for small spaces. Portable designs are perfect if you need to relocate your dehumidifier often. Heavy-duty designs work well for long-term, continuous operation in warehouses where they may encounter a lot of rough use.

Deciding which unit is right for you will require you to do some research and evaluate your needs before making a purchase. Start by calculating the square footage of coverage you need and narrow down your options from there.

How Much Does a Commercial Dehumidifier Cost?

Prices vary considerably, from less than $1,000 to above $3,000. It has a lot to do with design, construction, and features. Dehumidifiers that can cover a lot of space or have a lot of features will cost more.

You can’t judge a dehumidifier solely by its cost, though. Cheap humidifiers may work just as well for your purposes as expensive humidifiers. If you don’t need something feature-rich or want the job done fast, don’t waste your money. Price isn’t everything, especially if you’re on a budget.

Are Commercial Dehumidifiers Loud?

Typically, they are a bit noisier than dehumidifiers made for residential spaces. Some are louder than others, but compared to the sound of machinery in your warehouse, they are likely very quiet. In fact, you may never notice a humming dehumidifier.

When using a dehumidifier in a commercial environment, sound volume typically won’t be a big deal. However, the more heavy duty your unit, the higher the noise level (generally speaking). It has more powerful machinery that can produce a louder sound.

How do Commercial Dehumidifiers Work?

Dehumidifiers keep the air in your space free of excess moisture and humidity, helping to reduce allergens in the air like mold, mildew, dust mites, pollen, and more. They can make your working environment more comfortable, keep your employees from getting sick, and maintain your equipment.

Most dehumidifiers bring warm air into the unit via a grille on one side. The fan pulls air through the opening over cold pipes, creating condensation and removing humidity from the air. This treated air is then warmed to your desired temperature and ejected from the other side.

The primary difference between a commercial dehumidifier and a residential one is the capacity – obviously, industrial grade units tend to be larger and more powerful. Although some commercial dehumidifiers may have more features, the basic functionality is the same.

What are the Benefits of a Commercial Dehumidifier?

If you’re trying to operate an efficient work space and business, a dehumidifier can help you out a lot. There are plenty of benefits to hooking at least one up in your work space. Even if you don’t live in a warm climate, moisture can accumulate in any area if there’s not proper ventilation.

When you add humans to the mix, there’s sweat, exhaust from equipment, and other sources that can add moisture to the air in your facility. If you start to notice condensation on windows, water damage on the ceiling, or mold growing in the bathroom, it’s time to get a dehumidifier.

A dehumidifier can help you protect your investment in heavy equipment, making it last longer. It can prevent rust and corrosion on components and improve the daily use of your machines.

You may even find that you have to clean less often because a dehumidifier can help keep dust at a minimum. This can save you money on cleaning time and costs. It can also produce some health benefits by reducing allergens in the air.

You may also find that you’ll save money on energy. A dehumidifier can help your air conditioner work more efficiently by clearing the air of things that make it hard for an HVAC system to keep up. It can improve the lifespan of your HVAC system by reducing wear and tear.

In general, a dehumidifier keeps your space cleaner and more hospitable for people and equipment rather than for allergens and dirt. It will smell better, remain cooler, and stay cleaner, saving you time and money.

Next Steps

Now that you know more about the commercial dehumidifiers on the market, it’s time to choose one. You can’t go wrong with any of them on the list because they’re all high-quality units with great features.

It all depends on what you need. Evaluate your space and how much dehumidification you need and then take a look at your options. There’s a lot of information out there, so take your time.

Make sure whatever you choose will work for you, fit your needs, comes with the features you want, and has a price you can afford. Adding zeros to the price isn’t worth it if it does far more than you ever need it to do.

If your commercial dehumidifier has great features but won’t handle your large space, it’s counterproductive. Make smart decisions based on your budget and needs to get optimum performance out of your new commercial dehumidifier.
