What I like

What I love most about this commercial dehumidifier is that it’s made right here in the USA and comes with a 5-year warranty. You’ll want peace of mind knowing that if anything goes wrong with your investment, you’ll be able to do proper maintenance.

You can choose between either castors to stay mobile or leveling feet if you want to keep it in a fixed position. That’ll give you the flexibility to decide where and how you’re going to place your commercial dehumidifier, which is a plus over portable dehumidifiers.

This industrial dehumidifier removes excess moisture at up to 100 pints, preventing mold, mildew, odors, wood rot and is rated to cover up to 5500 square feet. It’s going to dehumidify a large space and it’s going to do it all without getting in the way!

You won’t have to deal with emptying the water out either, as you can set up a hose or keep this dehumidifier over a floor drain for easy draining. The simple to use display will allow you to choose from a plethora of options on how you want your dehumidifier to run.

What I don’t like

One feature that is missing over other commercial dehumidifiers is that it doesn’t have smart features. This can be a bit annoying as you’re going to have to go to where the dehumidifier is located to change any settings.

Another downside is that you’ll have to keep this hooked up to your HVAC system, which means that you won’t be able to transport it easily. If you’re looking for a portable dehumidifier, then check out the runner-up option.

Why I recommend this product

Instead of buying foreign, you’ll have the pleasure of knowing this was made in the USA, as well as a 5 year, backed warranty. For such a big investment, you want to have the peace of mind that should anything go wrong, you can count on getting your unit fixed.

That’s why this unit took the best commercial dehumidifier, it’s capable of keeping the humidity levels right where you want them and has a huge capacity that can take care of a whole house, office, or workshop.

It’s suitable for crawl spaces, but if you’re interested in a more portable dehumidifier, check out the Kesnos 232 Pint.

Also Great Commercial Dehumidifier

Kesnos 232 Pint Commercial Dehumidifier

  • Capacity: 232 pints
  • Warranty: 1 year warranty
  • Smart features: No

If you need a portable commercial dehumidifier, this Kesnos model has a capacity of up to 232 pints per day!

What I like

What I like most about this commercial dehumidifier is that you’ll be able to take it where you need it. Unlike the first option that’s stuck in a fixed position, this works in any odd scenario you’d need it to, as long as you have power available of course.

It can remove excess moisture at up to 232 pints per day. With its intelligent humidity control, it’ll sense the room’s humidity levels and adjust its operation as needed. You can decide to take over manually as well with its 24 hour timer.

Don’t worry about it overflowing as it has automatic shut off that’ll turn it off as soon as the bucket reaches capacity. Depending on your needs, you can adjust the humidity range from 10-98% giving you full control.

It has an auto defrost function if the coils freeze up, and it has an auto restart function if the power goes out. You can choose to set up an automatic drain hose if you wish to reduce the need to empty out the water tank yourself.

The display panel on the front will show you any error codes so if your dehumidifier has any issues so you can service them right away. The casters are a nice touch as well, so you won’t have any issue getting this portable dehumidifier where you need it to go.

Above all, you get a 1 year warranty and the option to extend your warranty for 2 years if you register your product.

What I don’t like

If it were my choice, I’d rather have my dehumidifier set up with the in-house HVAC system rather than having a big unit taking up space. But the fact of the matter is, you may need a portable dehumidifier to go where you need it, and that’s where this product comes in.

It also lacks smart features which for the price you may expect it to come with it.

Why I recommend this product

I think that if you need one of the best commercial dehumidifiers that’s also portable, but can service up to 8,000 square feet, you should look no further.

I would however recommend if you’re moving from job site to job site and need an ultra-portable option, you may want to look into BlueDri BD-BD-130-BL to take advantage of its wheels and handle.

Best Heavy Duty Commercial Dehumidifier

BlueDri BD-BD-130-BL Industrial Commercial Dehumidifier

  • Capacity: 225 pints
  • Warranty: 1/5 year warranty
  • Smart features: No

This heavy-duty commercial dehumidifier will be great in even the biggest of spaces.

What I like

This industrial dehumidifier was made to be transported. It has a big handle on the back as well as 2 big wheels to make it easy to tip over and transport where you need it to go. It can service commercial and industrial areas making this heavy-duty dehumidifier versatile as heck.

The front panel is super easy to use, with timer, power, scroll and purge options. It’s nothing fancy, but that means fewer moving parts to have to worry about if a touch screen stops working. It also has an automatic water pump, auto restart, RH, and temperature sensors.

It can remove 225 pints of moisture per day, which is going to be almost three times as much as the biggest home dehumidifier. The front is roto molded as well so you can rest easy if for any reason you ding the bottom, it should likely be fine as long as the contact wasn’t anything major.

The reusable filter is easy to wash and replace in an instant. The drain hose is super long coming in at 38 feet, so you can set up this commercial dehumidifier in almost any setting or difficult-to-reach job site. The automatic water pump can reach up to 5 meters and take water out from below, like a basement.

What I don’t like

Compared to other commercial dehumidifiers, the price of this one is a bit more than all the others. The display on the front is also a bit lacking and there aren’t any smart features, so you can’t control it from anywhere.

Why I recommend this product

I think that the ruggedness and portability of this commercial dehumidifier stands up over other options on this list. The automatic pump makes it perfect to use in basements as it can pump up to 5 feet. You’ll love that it’s built to last and is stackable if you’re wanting to use multiple at a time.

The downside is the digital control panel being a bit lacking, but overall this product will do what it does best, remove moisture from the air!

Best Budget Commercial Dehumidifier

ALORAIR Commercial Dehumidifier

  • Capacity: 113 pints
  • Warranty: 5 years
  • Smart features: No

This budget commercial dehumidifier will keep your home, workshop, or office’s humidity levels in check while keeping your wallet happy.

What I like

This unit is very similar to the unit that won our list of best commercial dehumidifiers. You’ll find that if you have a smaller space of around 1200 square feet, then you won’t need to purchase the biggest dehumidifier on the market.

With its MERV-8 filter, it not only dehumidifies, but it also cleanses the air by trapping dust and keeping the air quality fresh as can be. It can remove 113 pints of moisture from the air per day and is capable of withstanding rugged conditions with its tough enclosure.

If you live in cold areas, you won’t have to worry as the auto defrost functions keep the coils from freezing until around 36 degrees F. This is important if you’re looking to keep the relative humidity low while still operating during the winter months.

It’s energy-efficient as well as operates at a low noise level which is important if you have this in a home. It offers high speed dehumidification if you need to dehumidify an area quickly. You can set your desired humidity level to anywhere between 36% and 90%.

It’s great for any commercial settings like laundromats, carpet cleaning services, flood restoration environments, workshops or simply to remove moisture in a 1200 foot space. What I like most is that you’ll be able to stand behind Alorair’s 5 year warranty if anything goes wrong.

What I don’t like

I don’t like that the display looks cheaply made and the remote costs extra. More expensive units also offer the ability to keep your humidity levels even as low as 10%, but this unit only offers a range of 36% to 90%.

Why I recommend this product

This commercial dehumidifier intended for crawl spaces still compares to even higher priced units. I love that it’s energy-efficient by not being oversized for certain areas. You won’t have to worry either about low temperatures, this unit is rated to work even as low as 36 degrees.

You don’t have to overspend on a commercial dehumidifier and as long as you’re working with around a 1200 foot space, this unit will do you just fine.

Best Smart Commercial Dehumidifier

ALORAIR Storm LGR Extreme Smart WiFi Commercial Dehumidifier with Pump

  • Capacity: 180 pints
  • Warranty: 5 years
  • Smart features: Yes

Tired of having to run to your commercial dehumidifier just to turn it off? Well, no more with this ALORAIR smart dehumidifier!

What I like

What I love most is the included app that you’ll be able to control this unit from anywhere. If you’re having to get somewhere but have to keep a location dry, then you won’t have to worry about how or when you can shut off your unit. You can purge, turn it off, set the RH point and even find its location all through the smart app.

You don’t have to use the free app though, you can still control all the functions on the control panel on the front. The panel also looks like it’ll feel a bit more modern over some of the other units that I’ve reviewed on this list.

At 180 pints per day of moisture removal, you’ll be able to keep this powerful commercial dehumidifier working all day long without any issue. You can store a 19.6 foot cord and 19.6 foot condensate hose right on the unit so you can keep everything in one place. They’re also easily stackable if you wish to use a few at once.

This is one of the best commercial dehumidifiers I could find with smart features and I think that in today’s age, it’s neat to have the option and useful if you’re on the go a lot. You won’t have to worry about the outside as well from getting dented or scratched as it’s made out of rugged polyethylene.

What I don’t like

ALORAIR has difficulties with their app at times and can’t offer support as the app was built by another company. One user mentioned they had no way to get their email verified to use the app, but other reviewers mentioned that they had no problem getting it set up.

Why I recommend this product

While this unit does include a heavy price tag, it does offer smart features that’ll be convenient when you need to leave the job site. I like that the front panel seems heavy duty and the enclosure is well built even compared to pricier modeled commercial dehumidifiers.

If you need a more portable version, then I would recommend the ALORAIR Storm as it’s similar in features, but has a handle and wheels.

Also Great Smart Commercial Dehumidifier

ALORAIR Storm DP Single-Voltage Dehumidifier

  • Capacity: 110 pints per day
  • Warranty: 5 year warranty
  • Smart features: Full controllable app

ALORAIR doesn’t make just one smart commercial dehumidifier, you’ll be able to enjoy a portable enclosure with the full-featured app.

What I like

This ultra-portable dehumidifier comes with a smart app that helps you control as long as you and the dehumidifier are connected to the internet. With the app, you’ll be able to turn the unit off and on, set the humidity, purge the unit, find where the dehumidifier is and even control multiple dehumidifiers at once!

Compared to other commercial dehumidifiers that don’t come with a remote, you won’t have to deal with the frustration of getting up and fiddling with a clunky control panel. It’s great if you leave the job site but forget to turn off your industrial dehumidifier, with the app, you can control it from anywhere.

This commercial dehumidifier is rated for 110 pints per day of moisture removal. The heavy-duty construnction will be great for when you’re moving this dehumidifier where you need it to go. The BIG wheels on the bottom and the handle will make it super easy to transport to any jobsite.

It has storage onboard too for your power cords and condensate hose. If you don’t want to use the smart app, the front LCD display will let you set the operation mode you desire. To top it all off, ALORAIR offers a 5 year full warranty which in my opinion, is going to be needed with an expensive unit like this one.

What I don’t like

This unit is a bit more expensive than other units but you do get plenty of features to make up for it.

Why I recommend this product

Unlike the smart commercial dehumidifier that’s installed in a fixed position, this one can be taken with you anywhere. It has all of the features that Aprilaire E100 Pro 100 has, but has a handle, wheels, and a smart app to boot.

If you need to be on multiple job sites and have many dehumidifiers you need to control, the smart application will allow for easy access. You can easily stack these units as well making transporting a breeze. While the price is a bit high, you do also get a 5 year warranty for peace of mind.

Best Commercial Dehumidifier for Home Use

hOmeLabs 4,500 Sq. Ft Energy Star Dehumidifier

  • Capacity: 50 pints per day
  • Warranty: 2 year
  • Smart features: No

If you’re looking to beef up your dehumidifier game at home but don’t want to invest in an industrial dehumidifier, this unit is going to impress.

What I like

I love that instead of paying up to $1000 for an industrial dehumidifier, you can save hundreds of dollars by going with a consumer product. You’ll be able to service up to 4500 sq.ft and remove up to 50 pints of moisture per day with this at home dehumidifier.

The sleek appearance will blend in with any decor, unlike a clunky industrial dehumidifier that will surely stand out when situated in a home setting. The wheels on the bottom make it super easy to transport from room to room.

It has plenty of great features like automatic shut off, continuous drain operation, turbo mode and a comfort setting. You can choose what humidity level you’d like to set your environment at which is important as every space is different.

The water tank is on the bottom and you can see from the outside how full it’s getting. The filter is washable and is recommended to be cleaned every 30 days. This at home dehumidifier is even energy star certified, which can’t be said for the pricier commercial dehumidifiers on this list.

What I don’t like

This unit doesn’t come with a hose and isn’t as quiet as you’d like it to be for an at-home unit. Unlike crawl space dehumidifiers that hook up into your HVAC system, you may need to deal with warm air being circulated around your room which can make for a hotter environment.

Why I recommend this product

You don’t need to spend a ton of money to get comparable features of even the best commercial dehumidifiers. While it doesn’t have smart features like the ALORAIR Storm DP, it has wheels, continuous operation, and is rated to remove 50 pints of moisture per day.

This dehumidifier will be great in any large room, garage, or workshop under 4500 square feet. Enjoy your savings while keeping the relative humidity level where you’d like.

Also Great Commercial Dehumidifier for Home Use

Vremi 50 Pint 4,500 Sq. Ft. 

  • Capacity: 50 pints
  • Warranty: 1 year
  • Smart features: No

The Vremi 50 pint is another affordable alternative to commercial dehumidifiers.

What I like

With its 50 pint of removal capacity per day, you’ll be able to dehumidify a medium to large space without any issue. It’s 24.3 inches tall and 11 inches wide, so it’ll be able to be stowed away in an inconspicuous place.

The bottom has wheels and it has a handle for portability around your work, office or workshop. You can adjust your humidity level to your desired water removal capacity. The turbo mode is a nice touch too if you want to quickly dehumidify an area and turn off your unit.

You can decide to run this unit on a continuous drain if you’d like, but it has an auto shut off features if the tank gets full. The tank has a 1.8 gallon capacity and you can see how much water is inside from the outside window.

Reviewers mention that setup was super easy to use and they even enjoyed the warm air circulation when they ran this unit in extremely cold temperatures. It comes with a 1 year warranty as well if you have any issues with your dehumidifier.

What I don’t like

This unit runs at around 55-60dB which can be a bit much if you’re using it when you’re trying to sleep. It also doesn’t have smart features like the ALORAIR Storm which is a bit disappointing.

Why I recommend this product

Residential dehumidifiers are a great alternative to the best commercial dehumidifier on the market. At-home use cases don’t need a huge unit that removes 232 pints a day like the Kesnos 232 Pint dehumidifier.

With this product, you’ll be able to enjoy continuous drain, a warranty, and all the features that you’d expect out of pricier models.

Best Commercial Dehumidifier With Pump

hOmeLabs Commercial Grade 140 Pint Dehumidifier

  • Capacity: 140 pints
  • Warranty: 1 year
  • Smart features: No

If you need remove water in an upwards direction, you’ll need to rely on a pump like this commercial dehumidifier offers.

What I like

Need water to be removed vertically? Then worry no more, this dehumidifier with a pump will do just that. Reviewers mentioned they had no issue with it pumping up to 6 feet which is great if you’re working in a basement and have no where to empty out the tank.

The wheels will make it super easy to use and the handle makes it easy to transport. The washable mesh filter will make maintenance easy and you’ll not have to worry about purchasing new filters.

The side has a quick drain hose attachment to make it easy to set up a continuous drain. It comes with a 5 meter drain hose, and the pump will help drain that water where you need it to go. I also love the look of this unit, it’s a bit more modern then units like ALORAIR Storm.

It plugs right into a standard 120V port which is nice as you won’t have to worry about 240v outlets when transporting this unit. The front LCD display is very simple but doesn’t rely on a touch screen which can be a point of failure.

What I don’t like

The wheels are on the outside of the unit rather than built into the enclosure like on the BlueDri BD-BD-130-BL. It also doesn’t have smart features like its counterpart ALORAIR Storm.

Why I recommend this product

While it doesn’t have smart features and the wheels can leave something to be desired, the price is also around 30% lower than other comparable commercial dehumidifiers. I think that if you’re in need of a commercial dehumidifier with a pump, this one will get the job done.

Reviewers mention that they replaced other units that had failed them, and this one finally lived up to the promise. They enjoyed its quiet operation as well and noted the pump worked well.

Commercial Dehumidifier FAQ

How effective are commercial dehumidifiers?

Compared to their at-home counterparts, commercial dehumidifiers can remove up to 250 pints per day depending on the unit. They’re great for dehumidifying areas that have been damaged by flooding or if you need to keep an area’s humidity levels low.

How do you size a commercial dehumidifier?

To size commercial dehumidifiers, you’ll need to multiply the length of your room by its width. One tip though, most manufacturers will over-rate their own products as they don’t have any regulations to go off of. If you’re looking at a unit that’s just about covering your needs, then I recommend getting a bigger unit to avoid any difficulties down the road.

A unit that isn’t working at max capacity all the time is going to work better than a dehumidifier that’s struggling to keep up.

What is the largest capacity dehumidifier?

The largest capacity dehumidifier I could find covered up to 8000 square feet or around 250 pints of moisture absorbed per day.

Can a dehumidifier be too big?

Yes, a dehumidifier can be too big for your space. I recommend getting the perfect commercial dehumidifier for your sized needs, don’t go too under, or too over. You want your dehumidifier to work well and not struggle to keep up and be reliable and have good energy efficiency at the same time.

Wrapping it Up

If you’re looking to keep a commercial dehumidifier in a crawl space and be out of sight and out of mind, the Aprilaire E100 is an option o consider. It can control humidity levels up to 5500 square feet, can remove 100 pints of moisture a day and doesn’t have a water tray to worry about it.

If you’re on the go, the better option would be commercial models with wheels, like the ALORAIR Storm DP. It’s stackable, and has a handle and heavy-duty wheels to make it super easy to transport around.

If you have a garage, you may want to look into the best garage dehumidifiers instead.
