The 6 Best Crawlspace Dehumidifiers for Eliminating Damaging Moisture

Best Overall Crawl Space Dehumidifier

Alorair Storm LGR Extreme Dehumidifier

While it may not be necessary for a crawl space dehumidifier to look good, the Alorair Storm LGR Extreme does just that with its four available color options (yellow, blue, green and red). However, that’s not what makes it an excellent choice for protecting your crawl space. A wide operating temperature range from 33.8 to 104 degrees Fahrenheit, a nearly 20-foot power cord, low grain refrigerant (LGR) technology, the ability to remove up to 180 pints per day (PPD) of water and convenient memory restarting are a few qualities that do, though.

LGR is a method of cooling air more efficiently to help remove more water. The technology allows effective operation over a wider temperature range than non-LGR machines. Low-operating temps mean you can set the Storm LGR Extreme and forget it. The unit also features a Merv 8 filter, which traps most airborne particles larger than 3.0 microns (or roughly the size of the smallest mold spores).

Pros

• Condensate pump incorporated into the design
• LGR technology for increased efficiency
• 19.6-foot long power cord
• Powerful enough for restorations
• Includes five-year warranty

Cons

• No venting duct attachment points
