Reviews of the Best Commercial (Industrial) Dehumidifiers on the Market

#1. AlorAir LGR Compact Dehumidifier (Best Commercial Dehumidifier for Basement)

best commercial portable dehumidifier

This unit may not remove the most pints per day, 190 compared to 225, but the difference is minimal and the extra 35 only comes in handy when you live in a very humid region of the country. What it does have included in its design outweighs that lack in pint per day removal.

First, off it is waterproof so you can submerge it in water if you need to. That makes up for the PPM discrepancy right there. Plus, it has a built in pump, digital humidistat control, simple and easy to use control panel and timer.

In addition to all of that, you get a device that is very portable and capable of being placed in small places. With its large water tank, your emptying duties may not be as frequent as they once were.

Then it works in temperatures ranging between 33 and 105 degree Fahrenheit. Its plastic-coated cable helps maintain the 6.4 amps without worry. This unit uses about 640 watts when turned on but only draws 5.4A on a 115V power supply for energy efficiency.

It may be the best commercial dehumidifier for basement especially if that part of your home or building floods a lot. The 5 year warranty makes this dehumidifier an outstanding value as well.

What We Liked

  • It is waterproof
  • It removes large amounts of moisture every day
  • Operates in most temperatures
  • Humidistat control
  • Built in pump unit

What We Didn't Like

  • Shipped damaged
  • It may be underpowered
  • Hard to find local servicemen

#2. AlorAir Basement/Crawlspace Dehumidifier (Best Commercial Dehumidifier for Crawl Space)

Best Commercial Dehumidifier for Crawl Space

What makes this unit stand out is its remote control capability. Once you set it in position you just have to push a button to get the settings you want. Rated for 2600 square feet your crawl space or small business can be moisture-free.

On top of that, you have a device that removes up to 198 pints per day. That is not bad. You do not have to worry about excessive moisture in the air ruining your home or commercial space.

Two other selling points are the adjustable feet. You can level this unit out and make sure it is in the optimum position to work like it is supposed to. Plus, it comes with 2 carry handles. This allows you to have a friend help you move it where you need it.

Also, it can handle working in temperatures between 38 and 104 degree Fahrenheit. Then its epoxy coated coils help prevent damage to those coils. A ducting option lets you customize how this device will work for you. An automatic humidistat control is included.

BlueDri BD-130P 225PPD Industrial Water Damage Equipment Commercial Dehumidifier

This top commercial portable dehumidifier may remove up to 225 pints of excessive moisture per day but amount is not always the best indicator of quality or performance.

Its built-in water pump, timer, and easy to use controls just do not compete with remote controls or waterproofing. With that said, this is still a top dehumidifier that does a great job keeping your home or business humidity free.

The automatic restart function makes sure that power outages do not keep this unit from completing its duty once the power returns. Then it can be used in those buildings that have been damaged by floods, drying them out before too much harm has come to the buildings.

A 38 foot drain hose connects to the pump to make sure the water it removes from the air is taken far away from your building’s area. The control panel is not hard to use and only a few buttons control the whole operation. A reusable filter helps save you a few bucks by cleaning it instead of replacing it. The semi pneumatic wheels make this dehumidifier portable and easy to move from room to room without hassles.

What We Liked

  • Heavy duty
  • Can run for days without a break
  • Easy to use control panel
  • 215 PPD removal
  • Long drain hose

What We Didn't Like

  • Fan continues to run
  • You pay a small shipping cost for repairs
  • Very heavy

Aprilaire 1850 Pro Dehumidifier Review

Corrosion resistant coils help this commercial dehumidifier for crawl space remain in top working order. Its 5200 square foot rating makes unit ideal for those homes with large basements or crawl spaces.

Once turned on it helps reduce the chance of your home contracting mold, mildew and other germs that trigger allergies or asthma attacks. It also helps prevent rot from appearing in your wood frame and joists.

Adjustable feet allow you to keep it level even when the ground or floor is not. After you plug it in, this device has the ability to remove about 95 pints of moisture every day.

In addition, there is a continuous drain function that allows you to unwind the drain hose and place it in a drain. Or just place the unit over the drain and save yourself some work. An automatic humidistat lets you set the dehumidifier and forget about it.

Then the 70 pound weight may have you asking for help when you want to locate it in the right spot. But once in place, it will take a lot to move it out of position.

What We Liked

  • Long drain hose
  • Easy to use controls
  • Good for 5200 square feet

What We Didn't Like

  • Doesn’t always shut off when the job is done
  • Not really good customer service
  • Error codes interrupt service

Dri-Eaz LGR 7000XLi Commercial Dehumidifier with Pump Review

Built-in sensors has this device monitoring itself so all you have to do is position it, turn it on and let it go to work. The moisture removal capacity is about 235 pints per day and it comes with a pump to get that moisture out of your home fast.

Along with that ability, you can wheel this device to any spot in your home or business you need it in. The large semi pneumatic wheels make relocation very simple as does the handle.

It comes with a fold down handle, an onboard cord storage as well as plain English control panel. The humidistat and the features do not take much skill in setting. Then the stackable nature helps you save room when your warehouse storage area is cramped for space. A 25 foot power cord gives you lots of room for placement as does the 48 foot drain hose.

What We Liked

  • Easy to transport
  • Long power cord and drain hose
  • Tough construction materials

What We Didn't Like

  • Error codes pop up frequently
  • Very heavy

What We Found

In doing this research, we found out that commercial dehumidifiers with pump are every bit as good as whole house dehumidifiers. They may not cover every room in the house but they do make sure your basements or crawl spaces are very dry and moisture free.

Once set up these units can protect a home from mold and mildew and other bacteria keeping your family nice and safe. Then some dehumidifiers work under water or in very tough water conditions without needing a break for days.

Commercial portable dehumidifiers are there when you need them.

How to Choose a Reliable Commercial Dehumidifier

There are many important factors when you are choosing a commercial dehumidifier with pump. Here are some details to help guide your search:

  • Square footage - the size of coverage does matter. If your house is large you do not want a small dehumidifier, commercial or not. Large ratings cover smaller areas but the reverse is not possible.
  • Pints per day - the water removal capacity is very important. You may not need the full capacity all the time but it is nice to have it when you do. Whenever possible go large
  • Special features - having a waterproof dehumidifier tops pints per day capacity every time. You get more versatility out of the unit and you do not need to worry about flooding
  • Operating temperature range - the larger the better especially when your geographical area gets cooler but remains very humid.
  • Air flow - the larger the cubic feet per minute the device can produce the better it is for your home. A large CFM can make all the difference in how much damage is done by excessive moisture

The Advantages and Disadvantages of Using a Commercial Dehumidifier

One of the advantages of owning a commercial dehumidifier is that these units cover a lot of territory. Your larger home with its large basement or crawl space can be protected by one dehumidifier and not several. That will cut your electrical expense and make sure your home is a healthy place to be.

On the flip side, you may see a rise in your electrical bill expense because these units do use a lot of power when they are left on for several days at a time.

Another advantage is that they are portable and can be put into small spaces out of your way. They are also easy to relocate when you need to change their position.

The Winner is...

There were a lot of good commercial dehumidifiers in this roundup. Sadly there can only be one winner. The one we liked the most was the AlorAir LGR Compact Dehumidifier.

Not only did it have better features but waterproof trumps pints per day any time. You can use this dehumidifier anywhere at any time but the same cannot be said about those units that have high PPD ratings.

Final Words

When you are in the market for a good commercial dehumidifier always go for the best. The close competition above shows that you can pick any one of the 5 and have great results protecting your home or business. Each one has characteristics that should meet your needs.

My name is Justin Williams. I am the founder and blogger at (read more about us). I was an allergy sufferer and that is also the reason why I began my trek to finding the best dehumidifier for my own personal health issues. All of the dehumidifier top picks on the site were put through their paces by Lance Perez - our dehumidifier researcher. He put each one through a series of tests to see how well they performed.
