How dehumidifiers work?

The fan is responsible for moving the humid air over cold metal coil where the moisture condenses into water that drains through a drain hose into the bucket.

Types of dehumidifiers

The two main types of dehumidifiers are:
Portable units: to control basement or crawl space humidity portable units are most commonly used.
