8 Best Crawl Space Dehumidifier With Pump

The crawl space is a vital area of the home. it raises the lowest habitable area of the home above the base floor elevation (BFE) so that if there’s a flood, then habitable areas of the home wouldn’t be affected. Crawl spaces also allow outside air to circulate beneath the home, thus directly improving indoor air quality.

Unfortunately, the latter point also means that poor air circulation in the crawlspace can compromise indoor air quality throughout the home.

Maintaining proper crawlspace humidity levels is one of the first steps to ensure effective air circulation in the air area and thus promoting comfortable indoor air conditions.

This guide looks at some of the best crawl space dehumidifier with pump and later on discusses how to choose the right dehumidifier for your crawlspace.

Buyer Guide

You’ve probably thought, at some point, that you could do without a crawlspace dehumidifier; that the whole-house dehumidifier is enough. It’s possible. However, more often than not, you’ll need another dehumidifier located in the crawlspace to achieve the desired indoor comfort.

Let’s find out the benefits of a crawlspace dehumidifier and how to choose the best dehumidifier for your crawlspace.

Why the Crawlspace Gets Very Hot and Humid

The first thing you must understand is that the crawlspace is almost always more humid than the rest of the home. In the summer weather then the living spaces become damp, the crawlspace becomes even damper.

You may even find standing water in the crawlspace when the rest of the home is dry. There are a couple of reasons why;

  • Bulk water issues: Bulk water is standing water in the crawlspace. They can result from a variety of issues. Perhaps it’s a plumbing leak. Or, maybe the ground slopes outside the home.
  • Groundwater evaporation: If the ground is full of water, then some of that water eventually evaporates into the crawlspace. Sometimes the soil appears dry, but only because the moisture is evaporating into your crawlspace.
  • Outdated crawl space vents: Many homeowners install crawlspace vents to improve air circulation in the crawlspace. While it’s a good idea, the vents are often more of a problem than a solution. The vents can raise relative humidity (RH) in your crawl space by up to 22%, resulting in condensation on the walls and even causing pooling water.

Benefits of a Crawl Space Dehumidifier?

For one, a crawlspace dehumidifier resolves and can even prevent the three issues above, i.e., bulk water issue, groundwater evaporation challenges, and condensation due to outdated crawlspace vents.

Additionally, a dehumidifier in your crawlspace can be valuable in the following ways;

  • Health benefits

Hot, humid conditions are the perfect breeding ground for dust mites and mold. If you fail to address these issues, you’ll be treating allergies and multiple respiratory illnesses in no time. A dehumidifier in the basement effectively dries the moisture necessary to breed mold, thus saving you from potential health issues.

  • Preserve the building’s structural integrity

If the relative humidity in the crawl space exceeds 70%, you’ll most likely witness condensation. Condensation can cause wood rot, which happens easily when liquid water touches wood and there’s at least 28% moisture in the air. If the wood in the crawlspace rots, the crawlspace may not be able to hold the weight of your home anymore.

  • Improve energy efficiency in the home

You probably didn’t see this coming. But, yes, high humidity levels in the crawlspace can lead to higher energy bills in the rest of the home? Why? Because when we feel hot and sweaty, the first instinct is to turn on or turn up the air conditioner. Air conditioners are the biggest energy consumers in the home. It’s a lot cheaper to remove the excess moisture using a dehumidifier.

Factors to Consider When Choosing the Best Crawl Space Dehumidifier

  • Size/Capacity: Dehumidifiers size is measured in pints per day (PPD), which refers to the amount of moisture in pints the dehumidifier can remove per day. The most common sizes under the new DOE standards are 30-pint, 50-pint, and 70-pint.
  • Coverage area: One of the main factors that will determine the ideal dehumidifier size for your application is the area of the room/crawlspace. A larger area requires a higher-capacity dehumidifier. Fortunately, nearly all manufacturers indicate the recommended coverage area for each appliance.
  • Manual or continuous/pump drain: Manual drain means you wait for the tank to fill and carry it to the sink for emptying. Since this is a laborious process, the larger dehumidifiers often have a continuous drain feature so you never have to carry the tank to the sink again. There are two continuous drain methods – gravitational and by the pump.
  • Convenience features: The best crawlspace dehumidifiers are rugged to withstand the unusual conditions of the crawl area. However, that doesn’t mean you should overlook convenience features. Features to prioritize include self-defrost, auto-restart, presence of humidistat, presence of thermostat, and user-friendly control panel. If you can find one with remote or even smart/app control, that would be great.
  • Warranty: Every reasonable crawlspace dehumidifier manufacturer offers a warranty on each product. You want at least a full year on the general parts and three or more years on the condenser.

This unit from MOUNTO is almost as powerful as the preceding Aprilaire dehumidifier. However, unlike the Aprilaire, it’s a portable unit.

It also comes in a hardened plastic body rather than a metallic one. An LCD panel is located at the front of the unit so you can set your desired humidity levels with convenience. The displays indicate the humidity level and inlet and outlet temperatures.

Like every other dehumidifier on this list, it has a built-in electric pump that allows it to pump condensate from the tank. The pump allows it to remove 2-3-times more water than dehumidifiers in the same category.

It can remove up to 71 liters at maximum saturation (90˚F and 90% RH). This makes it the perfect choice for extra-large crawlspaces up to 7,000 Sq. Ft. It can also work in the basement or as a whole-house dehumidifier.

It has a built-in humidistat for an easy humidity setting and two carrying handles for effortless mobility. Unfortunately, you may need someone to help you carry it around as it weighs a massive 70 pounds. You can stack three such units if you wish.

Well, the ECOR Pro can. It’s one of a very small range of dehumidifiers that continue running down to -4˚F. Yes, you read that right- negative four degrees Fahrenheit. Considering that the standard dehumidifier cannot work at temperatures below 41˚F, you can easily tell that this one is built differently.

It’s a quality that makes it a great choice for the colder climates or just often cold places such as the basement and crawlspaces. It also works very well in vacation homes.

Will a dehumidifier work in the crawl space? Yes. Dehumidifiers work very well in the crawlspace. In fact, crawlspace dehumidification is critical to improving indoor air quality.

What size dehumidifier do I need for my crawl space? A 70-pint or higher dehumidifier under the 2020 DOE standards would suffice. However, always try to match the actual crawlspace area with the recommended coverage.

Where should a dehumidifier be placed in the crawl space? The dehumidifier should be located in an area where discharge airflow is not blocked. You’re also advised to place the unit on concrete blocks as hanging can transfer noise to space above.

Condenser vs. Desiccant Dehumidifiers, which is better? Condenser dehumidifiers are more effective, but also more energy-sapping. Remember that condenser dehumidifiers work like air conditioners. They rely on very cold refrigerant lines to condense the moisture in indoor air. Meanwhile, desiccant dehumidifiers use a desiccant chemical to absorb moisture from the air.

Should I buy a dehumidifier with a pump? Yes, if the budget allows. We say “if budget allows” because dehumidifiers with a pump are typically more expensive than ones without. You may have to spend up to $300 more. However, the increased convenience is worth the extra investment.


It’s critical that you dehumidify your crawlspace. If you’ve been unsure about it, just remember that the air quality in your home is directly determined by the air quality in the attic.

If there’s too much moisture, or, God forbid, condensation, in your crawlspace, air conditioning in the rest of the home automatically becomes a bigger task. Even the energy bills will rise. Fortunately, it’s very easy to find a good crawlspace dehumidifier.
