2. Dri-EAZ F413 Revolution LGR Compact Dehumidifier – Best compact high-performer

Dri-EAZ dehumidifiers are a favorite among home and business owners because of their small size relative to the power they offer. So, do not let the compactness of the F413 fool you. This commercial-grade machine can remove up to 120 pints of water from the air in a day.

The inbuilt automatic pump lifts the collected water up to a remarkable 17 feet. Furthermore, with professional help and additional supplies, you can connect the Dri-EAZ F413 to your ductwork. This additional investment will enable it to continuously dehumidify the air circulating in your home. 

Because it lacks a remote controller, the F413 is not as straightforward to operate as the AlorAir Sentinel SLi90.

This crawl space dehumidifier with pump offers reliable dehumidification for the long term.

This unit offers commendable performance. It can remove up to 70 pints of water per day. It also runs quietly and with little vibration. Aprilaire does not ship the 1820 Pro with an inbuilt pump.

  • Quiet operation
  • Clear, easy-to-use controls

The compact design makes this dehumidifier easy to position in tight crawl spaces. However, it is relatively heavy, which means you will probably need some extra hands where lifting is required. 

As expected with Mounto dehumidifiers, the MT 80 is a high-performance beast. It can remove anything between 80 and 120 pints per day depending on the temperature and humidity levels in your crawl space. The inbuilt pump eliminates any need to monitor the unit for full tanks and spillages. It can drain the condensate away for up to a vertical distance of 14 feet. 

The numeric LCD displays the humidity level and the inlet and outlet air temperatures. It also features buttons and dials for intuitive control. 

The Mounto MT 80 is a reliable dehumidifier for long-term use. It lacks the comprehensive warranty cover of some of its competitors, but it is more competitively priced.

Our Pick of the Best Dehumidifier with Pump for Crawl Space

As you have learned, crawl space dehumidifiers come in different sizes and capabilities. Some are ideal for enclosed areas that experience occasional dampness. Others are suitable for dealing with excessive flooding. Compact, portable options offer more placement flexibility. On the other hand, bulkier dehumidifiers often provide better dehumidification performance. 

The best dehumidifier for your crawl space is the one that best matches your needs and your budget. However, if we had to choose the best among the units above, it would have to be the outstanding AlorAir Sentinel HDi90. It ticks all the relevant boxes without being unreasonably expensive. 

The wireless remote controller is also a much welcome feature. Furthermore, its auto-defrost functionality makes it the perfect dehumidifier with pump for crawl space for all-year use. 

If you are looking for a more compact unit, our second choice, the Dri-EAZ F413 is an excellent alternative. It makes up for the lack of a Wi-Fi controller with better performance and portability. 

How to Buy a Dehumidifier with Pump for Crawl Space

dehumidifier iwith pump set up in a crawl space

Knowing the best crawl space dehumidifier with pumps on the market can reduce the time you take to make a decision. To choose the right unit, however, you must also know what you are looking for in a dehumidifier. 

In this section, we will cover the main factors to consider when shopping for your next crawl space dehumidifier.

1. Performance and Coverage area

Like all other dehumidifiers, crawl space units come with varying performance. Generally, the more the capacity, the larger the coverage area a dehumidifier can cover. High-performance dehumidifiers also take in more water in a day.

Before you go shopping, therefore, examine your crawl space. Take measurements so that you only consider the units that can match the size of the crawl space. 

Additionally, take note of the relative humidity. A simple, hand-held digital hygrometer like the AikTryee Mini can help you to determine how wet your crawl space gets. You can, therefore, decide whether you need the robust AlorAir Storm LGR Extreme 190PPD, the less-powered Aprilaire 1820 Pro, or something in between. 

2. Weight and dimensions

The purpose of measuring your crawl space goes beyond determining coverage area. You must also consider where you will place your new unit. Some of the most powerful crawl space dehumidifiers are also relatively large. The last thing you want is to buy a unit that is too big to fit in your space.

3. Pump draining power

A pump is a massive advantage for a crawl space dehumidifier. Because it drains the water for you, you do not need to go down to your crawl space to empty the tank. 

That said, dehumidifier pumps are not equally effective. The pump on the AlorAir Sentinel HDi90 can drain your water through a window that is as high as 14.7 feet from the unit. On the other hand, the Dri-EAZ PHD 200 can only lift condensate water up to a height of 5 feet. 

When shopping, therefore, consider where you want your drained water to go.

4. Extra features

Crawl space dehumidifiers are not as feature-packed as apartment dehumidifiers or bathroom dehumidifiers. However, going for a unit with some extras can make your experience significantly better. 

For instance, clear and easy-to-read controls minimize the risk of keying in the wrong settings. Meanwhile, a unit with anti-corrosion coils will break down less frequently than one with bare coils. If your location gets very cold in the winter, anti-defrost must be one of the key features to consider. 

Some crawl space dehumidifiers come with remote-control capability. The Santa Fe Advance100, for instance, can give you the convenience of monitoring the humidity in your crawl space right from your smartphone. 

5. Warranty

A crawl space dehumidifier is a sizable investment. As with any big purchase, therefore, you want to make sure you get your money’s worth. 

A unit with a decent warranty will stick with you for the long term. If something fails during normal operation, you can always reach out to the seller or manufacturer to get it fixed at no cost. 

When comparing warranties, read through the fine print. Some companies may claim to offer lengthy covers but only cover specific parts instead of the whole unit. Ensure you get a comprehensive warranty that will stand with you at least a few years into the future. 

Wrapping Up

Crawl spaces are notorious for harboring excessive wetness. With the right crawl space dehumidifier with pump, you can fix the problem once and for all. 

We hope you will find our guide helpful in your quest for the best appliance. High indoor humidity can adversely affect your health and quality of life. Stay safe and comfortable by maintaining the right moisture level in your home.
