Top 5 Crawlspace Dehumidifiers

1. AprilAire 1710A Dehumidifier

At 90 pints per day, the water removal capacity of the AprilAire 1710A is higher than almost every other model in the crawl space dehumidifier category. Easy to use controls, steel construction, auto-defrost feature, and a supplied hose and P-trap all make the 1710A easy to use and install in your crawlspace or basement. A MERV 8, replaceable air filter, far surpasses simple nylon mesh filters that are common with other dehumidifiers, and a 5 year warranty provides peace of mind that is nearly unmatched. Made in the USA, the price is around the upper middle of the scale, and the only drawback of note to this crawlspace dehumidifier is the lack of an internal condensate pump.

2. Ebac CD85

Made in the UK, with a steel frame and body, the Ebac CD85 is a highly versatile crawl space dehumidifier with a variety of features that makes it an excellent solution to most residential moisture control problems. By removing up to 56 pints of water per day from the air in your crawlspace, the CD85 dries efficiently and conveniently pumps water away with an internal condensate pump. Configurable and compact the CD85 fits between joists or anywhere you have room. Simply set the humidity setting, and let the CD85 do the rest. Blow away any debris or dirt that accumulates around the coils and blow the air filter out annually, and the Ebac CD85 is an ideal, semi-permanent solution to excess moisture.

3. Dri-Eaz CMC100 Dehumidifier

With a variety of great features, the CMC100 is a can't-go-wrong crawlspace dehumidifier. Water remove capacity (70 pints per day) is better than nearly all comparable models, and and an internal condensate pump provides versatility to move water outside of the crawlspace even when gravity's not on your side. The CMC100 can be ducted to pull in outside air, dry it, then release it into the crawl space to help create positive air pressure. The panels are interchangeable and configurable which also make the CMC a great fit in basements, and an easy-to-read digital read-out provides real-time humidity readings. A steel frame and body means this compact dehumidifier will more easily withstand the rigors of a crawl space environment. The Dri-Eaz CMC100 has an auto-defrost feature and is the only model in this class that is Energy Star qualified.

4. Ebac CD60

This UK made crawlspace dehumidifier offers contractor grade quality and performance that will tackle even the worst crawl space moisture problem. A steel frame and body lend durability to this unit while leveling feet make it ideal for the uneven terrain of dirt crawlspaces. The water removal capacity (51 pints per day) is better than 3/4 of the other crawl space dehumidifiers available, and the integrated condensate pump allows you to push water up grades. Requiring little more than annual cleaning of the coils, the CD60 is low maintenance and has an auto-defrost feature. Ideal for commercial applications, the CD60 can dehumidify a massive volume of air quickly and works well in any size residential crawl space.

5. Ebac CD30E

If price is a major concern when trying to remedy a damp crawlspace, the Ebac CD30E can be a low cost solution. Though the water removal capacity is the lowest of our top 5 models (17 pints per day), under more extreme, humid conditions, it will still remove nearly 4 full gallons of water and can effectively dehumidify spaces up to 3000 cu. ft. Compact but efficient, the CD30E features a durable steel frame and body and a hot-gas defrost features helps keep it functioning at its best. Easy-to-use controls allow you to set it and forget it. The lack of an internal condensate pump means you need to situate the CD30E where gravity will allow the extracted moisture to flow away, but as an economical solution to a wet crawlspace, the Ebac CD30E can't be beat.
