Best Commercial Dehumidifiers In 2022
Is a small, residential dehumidifier just not cutting it? If you’re reading this article, you’ve probably realized that you need a bigger piece of equipment to control the humidity in your space. This might be the case if you live in a large home, a home with water damage, or own an inside pool. Or perhaps, you need a commercial dehumidifier for your business. Whatever the reason, we’ve been searching for the best commercial dehumidifier that money can buy. Here are our top seven commercial dehumidifiers.
The Best Commercial Dehumidifier
AlorAir makes a whole range of impressive industrial dehumidifiers. This model – the Sentinel HD55 – is designed specifically to be used in basements and crawl spaces. At 13.3 inches tall and 12.2 inches wide, it’s small enough to fit into those tight gaps and comes with two low-profile handles to make it easy to carry. You’d think, at this size, it wouldn’t have a whole lot of power but it can actually pull 55 pints of moisture out of the air every day. It might be small but it can pack a punch.
The reason it has this much power, in such a small unit, is because it doesn’t have an integrated water tank. Instead, it needs to be hooked up to the 2m drainage pipe (included), so the water has somewhere to go. It also has a Hot Gas Valve Defrosting System, which allows the dehumidifier to work at low temperatures (36ºF) without having to stop during the defrosting process. This makes it more versatile and considerably more efficient.
For spaces up to 1,300 sq. ft.

The Dri-Eaz Revolution LGR Commercial Dehumidifier is one of the most innovative dehumidifiers on the market. We already featured the Dri-Eaz LGR 7000XLi as our Premium Product, and we think that’s the best commercial dehumidifier money can buy. So why would you buy the Dri-Eaz Revolution LGR? Well, it has one main benefit – its size. It’s absolutely tiny compared to most commercial dehumidifiers and you still get amazing performance.
The reason they’ve packed this LGR technology into such a tiny housing is so that tradesmen can fit more drying power into their trucks. By choosing one of these machines, you can save loads of space for other tools. Admittedly, the power isn’t as impressive as the full-sized Dri-Eaz dehumidifiers, but it is still powerful enough for most industrial situations.
It has a maximum removal rate of 139 pints per day and can still remove 80 pints per day in AHAM conditions. That’s not world-beating performance, but it’s still a lot better than most industrial dehumidifiers. They’ve achieved this power by using the same Advanced Crossflow Technology they use in their full-sized models. This technology makes it much more efficient because the air temperature isn’t being changed when it doesn’t need to be.
Again, like the full-sized models, the Dri-Eaz Revolution LGR has a practically indestructible polyethylene housing. This machine is a little bit more prone to damage, thanks to the exposed parts, but it’s still one of the toughest around. You have to buy this dehumidifier if you want the best performance from a small machine. You can fit it into small spaces, and it stacks perfectly if you need to buy multiple machines. It costs a lot of money, but you won’t find a better compact commercial dehumidifier. Be sure to also check out our guide to the best tower cooling fans for more excellent products for your home.

The BlueDri BD-BD-130-BL is one of our favorite commercial dehumidifiers. It has the same kind of power that we’ve seen in the dehumidifiers that require professional installation, but this machine is much more portable. It has a handle, large wheels, and a roto-molded body, making it easy to move around and place it where it’s needed. It also has an 11-meter drainage hose that can be rolled away and tucked into the back of the body. This makes it so much easier to live with than a commercial dehumidifier with a bulky industrial drainage hose. Considering how portable it is, you would think that it lacks performance. Fortunately, that’s not the case at all. It removes up to 225 pints of water per day and is perfect for large basements and crawl spaces. If you’re looking for an easy life, this dehumidifier is the way to go.

This product has been built to last with its corrosion-resistant aluminum coils so that you can leave it down in your basement for years to come and trust that it will continue to do its job. The Aprilaire 1830 Basement Pro Dehumidifier, filters up to 70 pints per day and is made to best suit a 2200 sq ft. basement.
Reduce the humidity in your basement and prevent damage caused by excess moisture. Also with this product, you can enjoy its additional benefits with its ability to prevent mold, termites, wood rot and even unwanted odors. It has been created with the user in mind as the brand has gone to great lengths to ensure that setup and usage is as easy as possible. To empty such a device at the end of the day, a hose can be attached and you also have the option of holding the device over a drain.

If you want to spend a little more money on your commercial dehumidifier, you could get the BlueDri BD-76P. It’s still not the most expensive machine, but it’s just edging over the $1000, which means it’s got some pretty stiff competition. So, why would you choose this over one of the alternatives? Its performance isn’t that different from the other commercial dehumidifiers in its class. It has a maximum moisture removal of 150 pints per day and removed 76 pints per day when tested at AHAM conditions. So, it’s far more powerful than a residential dehumidifier, but it doesn’t stand out amongst the competition. For example, the AlorAir products will take slightly more water out of the air than this one and the price is around the same.
One of the big advantages of this dehumidifier is its rotomolded polyethylene housing. This is a feature we’ve only seen on the much more expensive products like the Dri-Eaz LGR 7000XLi. It means that this machine can take a bit of a beating when you’re carting it around into water-damaged areas. However, they don’t make any mention of it being waterproof, which is a bit of a downside. It does have a rigid handle and semi-pneumatic wheels, so it’s a lot easier to move than most industrial dehumidifiers.
One of the most impressive bits of technology on the BlueDri BD-76P is the high-efficiency rotary compressor. It means that it can offer impressive performance whilst only drawing 5.5 amps. Plus, it’s designed to be easy to cart in and out of vehicles and building, which makes it great for tradesmen.

Our Best Choice product on this list is the AlorAir Basement/Crawlspace Dehumidifier 198PPD. Whilst this wasn’t an easy choice, we thought this one edged it as the best all-rounder. Now, you might think from the name that this dehumidifier is specifically for basements and crawlspaces, but it can be used in any application. The reason it’s so effective in these spaces is that it’s compact and can be controlled via remote control.
The stats on this commercial dehumidifier are pretty impressive. It can remove up to 198 pints of moisture out of the air every day. Of course, every space has slightly different conditions and your dehumidifier might not perform at this level, but it should still perform pretty well in any conditions. It’s been tested at AHAM (Association of Home Appliance Manufacturers) conditions, which are 60 percent humidity and 80 degrees Fahrenheit, and it removed 90 pints per day.
Another reason this dehumidifier is so popular is that it’s easy to install and use. There isn’t much more to do after you’ve plugged it in unless you are using the remote-control function. The remote control has to be bought separately, but it allows you to monitor the dehumidifier and set it to run on sensors, so it’s worth the extra money.
This product also has added features like the heavy-duty condensate pump, which is more durable, and free from common issues like overheating, detection failure, and rusting. Plus, it has an epoxy coating on the coils to avoid the fatal problem of Freon leakage. All in all, if you’re looking for a compact, but powerful commercial dehumidifier, this is one of the best in the business.

One of the best things about AlorAir as a company is that they make dehumidifiers fit for specific purposes. You could use any of their products as a general-purpose dehumidifier, but if you have a specific problem – like water damage – you can find a commercial dehumidifier that is designed for that job. The AlorAir Storm LGR Extreme is designed to tackle water damage and has a range of features that make it fit for that purpose.
It’s actually not quite as powerful as the AlorAir HDi90, but it’s not far off. It can remove 190 pints of moisture out of the air per day and an impressive 85 pints per day at AHAM conditions. And it’s energy-efficient drawing just 5.5 amps on a 115V power supply. So, why would you choose this dehumidifier for water-damaged areas?
Well, firstly it has a waterproof design. The rubber strip around the dehumidifier protects the circuit board and allows you to sink it into the water. This is extremely useful if you have a water-damaged basement for example, and there’s nowhere to put the dehumidifier. In addition to the waterproofing, it has a similar epoxy coating to the previous AlorAir dehumidifiers. This stops the coils from corroding and extends the life of the machine.
We also really like the fact that this product is designed to be stackable. This might not make a huge difference to some customers, but it helps save valuable space when transporting these products to flood-damaged areas. As you delve deeper into this product’s features, you’ll find all sorts of useful things like an extra-long power cord and a storage hook to keep the hose. In terms of design, it’s far more advanced than a lot of commercial dehumidifiers, and because of that, we love it. Our guide to the best air purifiers features more amazing products that will keep the air of your home clean and fresh.

The Dri-Eaz LGR 7000XLi is the best dehumidifier in the business. If you really want performance, and you’re not concern about the cost, this is the dehumidifier for you. One look at the performance stats and you’ll quickly see it’s in a league of its own. It can remove a maximum of 235 pints of water per day and can remove 130 at AHAM conditions. That makes it nearly twice as powerful as other leading dehumidifiers and means that it can handle almost any commercial setting.
So, how does it manage to outperform everything else? Well, for a start, it’s bigger. Unlike AlorAir products, it’s not designed to be portable. It’s still not massive and you can still move it by hand, thanks to the handle and wheels, but you’re not going to get it into a crawl space. The extra size means it needs extra power, drawing 8.3 amps. So, we wouldn’t recommend buying this machine unless you really need it.
However, the main reason it performs so well is Dri-Eaz’s Advanced Crossflow Technology. In layman’s terms, this basically means that the air passes through the machine without changing temperature, improving the performance. The air stays cold when it needs to stay cold and heats up when it needs to. This maximizes efficiency and makes it the best performing dehumidifier around.
Other impressive features include a self-monitoring system that adjusts the fan speed automatically, so it doesn’t waste any power; and a built-in humidistat with easy-to-understand controls. All of this technology is housed in a practically indestructible rotomolded housing, which protects it from dents and scratches. This is the best dehumidifier in every way, but that performance is going to cost you a lot of money. Be sure to also check out our reviews of the best AC wall units and find the one for your home.

The XPOWER XD-125 is another midrange commercial dehumidifier that we thought deserved a mention in this list. It’s by no means the most powerful machine we’ve featured, but it’s a reliable workhorse and is a perfect option if you want to spend a little bit more money. If you look at the performance figures alone, it’s hard to see why you should spend an extra couple of hundred dollars on one of these machines, when you could go for a BlueDri BD-76P or a Perfect Aire 1PACD150. And the simple reason is that it’s reliable and works automatically.
It’s protected by a rugged housing that can withstand a serious beating. These machines are well-known to provide a good few years of consistent use. Plus, there are no negative Amazon reviews that complain about the machine failing. However, unfortunately, this is only backed up with a one-year warranty. So, you really have to hope that your machine doesn’t fail.
The performance is decent, removing 125 pints per day in a totally saturated environment. Plus, in AHAM conditions, it can still remove a solid 76 pints per day. That’s not going to win any awards, but it will still remove moisture fast before mold or mildew start to form. With that in mind, we’d say that this is one of the best commercial dehumidifiers for drying out basements and water-damaged rooms.
The other main benefit is the advanced recessed digital control. Set up your desired humidity and the machine will do the rest of the work. It will also automatically purge water when the tank is full, so you don’t have to manually monitor the tank levels. We have prepared our selection of the best moisture meters that will help you fight humidity in your home, so check them out.

Commercial Dehumidifier Buying Guide & FAQ
Size - The purpose of looking out for the size is mostly because this is a determiner for the capacity of the dehumidifier. Bigger, more industrial machines will filter out more water and therefore work endlessly. However, size is also a factor to consider in terms of the room the dehumidifier will sit in - smaller rooms are best suited for smaller dehumidifiers and this is for obvious reasons.
Humidity Control - On some machines, humidity is controlled automatically; however, on most dehumidifiers, it is up to the user to set their own preferred humidity levels. This can be done using buttons attached to the product or in some cases a remote control. The humidity control setting set by the user will determine how much moisture is filtered out by the machine.
Water Capacity - The amount of water a dehumidifier can hold well determines how often it needs to be emptied. This is important because no one wants to have to constantly need to empty their dehumidifier. With machines that can hold larger water quantities, you can rest knowing the product can carry on with its work for longer periods.
The best type of dehumidifiers in this regard, are machines that either come with a drainage system attached or at least allow for a hose attachment. This would mean that it will automatically be emptied and you do not have to constantly check on the machine.
Noise Level - Especially in your home, nothing would be more annoying than a loud and obnoxious machine. Low noise level, therefore, is essential especially with dehumidifiers that will exist in the same space with you. This way, the machine can work non stop in the background.
Sometimes, however, with larger more industrial machines, higher noise levels are inevitable. This is mostly okay in spaces where noise levels would not be a problem such as crawl spaces or large supermarkets. In this case, high noise levels can just assure you that your machine is working as it should.
Energy Efficiency - Because dehumidifiers are used frequently or even constantly, it would only be an added burden if they drove up the electricity bill. A lot of brands, therefore, take care to make sure that their products are energy efficient. Look out for these as they will conserve energy and also save you a fortune on bills.
Size Of Room - Most dehumidifiers will specially mention what size of the room they are best suited for. This is important because larger, commercial use dehumidifiers in a living room might just be a nuisance due to size and noise level, while smaller dehumidifiers might not have the capacity to work in larger spaces. Always look for the size of the room recommended by the brand.
Automatic Shut Off - This is important as it just makes your job easier. In fact, the more automatic functions a dehumidifier has, in most cases, the better - this means you will have much less to worry about. Dehumidifiers will most likely only shut off automatically due to a water capacity being reached. When this happens, it will serve to also notify you that it is time to empty your machine.
