Can you use a regular dehumidifier in a crawl space?

While you certainly can install a regular dehumidifier in your crawl space, the results will be less than successful, and it will involve a lot of work on your part to keep it in good condition.  

A regular, big-box store dehumidifier is not designed for use in such a large humid area. This means it has to run constantly to keep up, sending your energy bills through the roof. 

Dehumidifiers designed for use in a basement also commonly need to be emptied. While not impossible, climbing in and out of your crawl space to empty the dehumidifier, often daily, is a huge hassle.  

Instead, choose a specifically designed crawl space dehumidifier to work in hard-to-reach areas with a large volume capacity.
