Dehumidifiers for crawl spaces are pretty expensive. For this reason, you will not want yours to break down quickly. So, when buying one, make sure it has sturdy housing that protects the internal part from damage. Good protection of the internal part means less maintenance.

Area Coverage

Before you buy a dehumidifier, check the size of your crawl space. This is because different dehumidifiers are designed to dehumidify different sizes of rooms. Therefore, if your crawlspace is, for instance, 3000 square feet, go for a unit that dehumidifies up to 3,000 square feet of space.

Compact Size

Compact dehumidifiers not only fit in tight spaces but also they are easy to transport.

Energy Efficiency

Your dehumidifier is likely to run for several hours every day. So, if yours happen to be consuming a lot of energy, then sorry you; prepare to deal with high electric bills. With that being said, check whether a dehumidifier for crawl spaces is energy efficient before you make a purchase.
