ABSTRACT:
A ventilator system for a bed that withdraws air from under the bedding covers to provide fresh airflow along a sleeper's body is disclosed. The bed ventilator system includes an air removal extraction device at one end of a single bed, or along the lower-half sides of a shared bed, between the bottom sheet and the bed covers at the mattress top surface. A conduit directs withdrawn air from the extraction device to a vacuum generating system that provides negative air pressure as a motive force to withdraw air. The system provides air flow in the natural hair follicle direction, relieving bed occupants from both temperature and bodily odor distractions.
