A system for drying the crawlspace of a home, reducing mold in the crawlspace and in the living area of the home, and that creates healthy air exchanges in the living area of the home with fresh air from the outside. The Negative Air Supplied (NAS) crawlspace system implements multiple drying theories to efficiently dry both porous and semi-porous materials in the crawlspace down to moisture levels too low for mold to grow. The present NAS system also creates a negative air pressure in the crawlspace, which causes the airflow in the home to go from the living area to the crawlspace. This airflow pattern prevents any mold spores in the crawlspace from entering the living area of the home. The airflow created by the NAS system also forces multiple air exchanges per day in the living area of the home with outside air.
