A system and method utilize one or more fans each having fan blades. The fan blades have a desiccant material on an outer surface. The desiccant material is operable to adsorb airborne moisture in an ambient airflow and desorb moisture in a heated airflow. The fan blades are operable to drive one or both of the ambient airflow and heated airflow via rotation of the fan.
