What features usually come with a crawl space dehumidifier?

Modern crawl space dehumidifiers usually have the following features:

  • A Hygrometer. This measures the humidity levels currently in the crawl space.
  • Constant draining. Many units come with a drainage collection tank, which, when full, will shut the unit off. Other units have continuous drainage or a combination of both. The recommended method for a crawl space is continuous drainage.
  • An adjustable humidistat. This is used to set the desired level of relative humidity. The standard level is between 30 and 40 percent.
  • An auto-defrost system. If you live in the colder states, then this will prevent frost build-up on the coils.

Tosot 50 Pint Dehumidifier for 3,000 Sq. ft

Coverage area:  up to 3,000 sq. ft.
Dehumidification performance (pints per day): 50
Pump:  no
Water tank capacity: 2 gal.
Dimensions: 14.8 x 11.4 x 24.0 inches
Warranty:  1-year limited
More features: quiet operation at 52 dB; LED display controls

When it comes to the best crawl space dehumidifier, you might think that you will only get the best machine if you spend the most money. While this might be true for some models, it is, thankfully, false as far as this dehumidifier is concerned. This appliance is exceptionally budget-friendly, as it is by far the cheapest model available on the market today. This makes it an excellent choice for anyone looking to save a bit of money while also controlling the humidity level in their home.

What makes this such a great value is the fact that it is so simple to use. The controls on the top of the machine are easy to set and read, even in a dark crawl space. This appliance is also extremely mobile, thanks to the wheels on the bottom. You shouldn’t have any issue whatsoever getting it into place once you have it in your crawl space. The coverage area is also quite large for the price, as this model is capable of dehumidifying any space up to and including 3,000 square feet.

One thing that is a bit of a concern with this dehumidifier is the lack of a pump. While this model has a continuous drain option, it will need to be drained directly into a drain or external pump, which will end up costing you some extra money. You could also empty the tank manually. The Tosot does have a high-capacity tank, but will still need to be emptied at least once per day if you have an extremely wet crawl space.

What do we love it for?

Quiet operation
High-capacity tank
Large coverage area
Easy to read and operate controls
What were we disappointed with?

Does not have a pump
Low dehumidification performance

ALORAIR Basement/Crawlspace Dehumidifiers 198 PPD for 2,600 Sq. ft

Large spaces with serious excess moisture issues might require a bit more power, and a heavy-duty upgrade unit like AlorAir’s Basement/Crawlspace Dehumidifier might be the way to go. This model features a 198 PPD rating in saturated conditions, giving it enough power to cover spaces up to 2,600 square feet.

This model from AlorAir isn’t just capable of handling larger spaces, it also has convenience features like automatic defrost and compatibility with a remote control (though it’s a separate purchase). If the power goes out, the automatic restart will kick on and begin dehumidifying without user input.

This unit comes with a condensate pump already installed, allowing users to remove water with ease, pumping the water away instead of relying solely on gravity. This makes for more versatility during crawl space dehumidifier installation.

Product Specs

  • Coverage Area: 2,600 square feet
  • Air Flow Capacity: 210 CFM
  • Pint Capacity: 198 PPD


  • Suitable for large crawl spaces

 up to 2,200 sq. ft.
Dehumidification performance (pints per day): 
25 x 12.5 x 12.5 inches
 5-year limited
More features: corrosion-resistant aluminum coils; engineered and manufactured in the USA

If you are in the market for a no-frills, easy-to-use, and easy-to-setup dehumidifier for your crawl space, then this just might be the model for you. It is extremely easy to operate. All you need to do is place the model on a level spot, plug it in, set the humidity level you desire and let the unit take care of the rest. It is a completely automatic operation that will run only until the humidity level reaches your desired one. After that, it will automatically shut down until the humidity level starts to go back up, which will make it turn back on.

This model is also built to be used all day, every day. The corrosion resistant coils help to keep it from breaking down, which makes it an excellent option for use in an incredibly moist environment. It is unfortunately not suited for colder temperatures, so keep your crawl space temperature in mind before you decide upon this model.

Something that is really surprising about this unit is its high-performance level. It is able to remove up to 70 pints of moisture per day from a 2,200 square foot space, even though it is so compact and easy to move.

This dehumidifier comes with a drain hose that is on the shorter side, which might make it difficult to reach a drain. If, however, you don’t have a drain for it to empty into, you will need to buy an external pump, as this model does not have an internal one.

What do we love it for?

Long warranty
High-performance level
Compact design
Corrosion resistant coils
Large coverage area
Easy to setup
Simple control system
What were we disappointed with?

No pump
Not good for colder temperatures
Provided hose is too short

Vacplus 1,500 Sq. Ft. 30 Pints Dehumidifier

  • Tank Size: 2.8 pints
  • Room Size Availability: 1,500 sq. ft
  • Weight: 20.9 lbs.
  • Special Features: Intelligent humidity control, antibacterial filt


  • The auto shut-off and dual drainage modes are a big plus
  • Running it in continuous mode really pulls in the moisture
  • Easy to set up and use, following the simple instructions
  • Once you set the humidity level, it stays at that level


  • We wish the unit came with a slightly longer drainage hose for easier placement
  • The water collection tank could be a little bit bigger

With a superior quality compressor, the 1,500 sq. ft. dehumidifier from Vacplus can quickly remove up to 30 pints of moisture from your crawl space every 24 hours. It features intelligent constant humidity control with automatic adjustment. Set your target humidity level and the unit will constantly sample moisture in the air and make the relevant adjustments to maintain that setting. The simple controls on the top of the unit have a power on/off button, fan speed, mode, timer, and humidity buttons, plus a digital readout screen.

A useful feature of this dehumidifier is its 2-way timing. It has a timed boot and shutdown function which allows you to program the 24-hour timer to take advantage of any cheap, off-peak electricity rates. If you choose to make use of the collection tank, then the unit will automatically shut off when the tank reaches capacity. 

However, if your crawl space is typically difficult to reach, you may prefer to “set it and forget it.” To do this, you connect the included dehumidifier drain hose and the unit will drain via gravity. Both the collection tank and the drain hose connection are located at the rear of the unit, along with the washable, antibacterial filter.

Using a high-precision humidity sensor, the unit will sense when the humidity reaches your pre-set limit and go into standby mode. As soon as the humidity level rises the dehumidifier automatically starts again and continues extracting moisture until the level drops to the pre-set, helping to prevent issues such as mold and mildew from becoming a problem.

Tenergy Sorbi 1000ml Air Dehumidifier

Product Specs

  • Coverage Area: 200 square feet
  • Air Flow Capacity: 22 CFM
  • Pint Capacity: 1.6 PPD


  • Suitable for very small spaces
  • HEPA filtration system
  • Automatic shutoff
  • Quiet operation


  • Short power cord
  • Small tank may require frequent emptying

A standard dehumidifier will improve the air quality of your space by limiting musty odors, mold, and mildew. When you add an air purifier to the mix, then you’re also directly reducing dust mites, pollen, pet dander, and other allergens at the same time. With this hybrid model from Tenergy, you’ll get double the comfort from one unit.

The dehumidifier feature can remove 750 milliliters of moisture per day in environments with an 80 percent humidity level at 86 degrees Fahrenheit. When the 33-ounce/1-liter water tank reaches full capacity, an automatic shutoff will prevent overflow. Using a true HEPA filtration system, this small dehumidifier can also remove up to 99.97 percent of microparticles and allergens from the environment at the same time.

It may cost more than a standard small dehumidifier, but having the benefits of an air purifier in the same unit can save both space and money in the long run. This small dehumidifier is ideal for spaces up to 200 square feet, and it runs at a quiet 35 to 42 decibels.

Ebac CS60 Crawl Space Dehumidifier


  • Hot gas defrost
  • 56 PPM
  • Space-saving design
  • 25-foot cord


  • Fan runs continuously
  • Coverage for the price

Whenever a company puts the word crawl space into the name of their product, you know they mean business. That’s the case with an Ebac CS60 crawl space dehumidifier, which is built for tight spaces and smaller areas that require special attention.

With the Ebac CS60, you get a dehumidifier rated to handle up to a 1,500 square foot room. It has a washable slide-out filter in a fan that runs continuously, although the noise level is minimal at 57 dB. As for the dimensions, this system measures 14”H x 14”W x 20”D, which is about the average for this range. In other words, it should fit securely in most crawl spaces.

This machine can move quite a bit of air, considering it can process 360 cubic square feet of air per minute. It can pull up to 56 pints of moisture per day from your crawl space under ideal conditions and has an efficient rotary compressor. A set of rubber feet will help to dampen any vibrations from the system, and they’re two collapsible handles in case you need to move the unit for taking on the go.

From a hot gas defrost and feature to the easy-to-use industrial design, there’s a lot to like with the Ebac CS60. With the right accessories, you could make this system fully automatic, although the warranty isn’t as good as you’ll find from other manufacturers. Ebac provides a one-year unconditional warranty on the system itself to go along with a 3-year guarantee on the compressor, condenser, and evaporator.
