Abstract
The present invention provides a vented individual negative pressure enclosure system for extracting potentially contaminated air from an individual. The system includes an adjustable assemblable and disassemblable frame structure configured to surround a bed, chair, or toilet. A vapor-impermeable sheet extends over the frame structure. An air purification system communicates with a plurality of extraction vents positioned on or in the frame structure. The air purification system may be a water-filtration-based air purification system including a particle growth tube for increasing the size of aerosol droplets to facilitate capture. The air purification system includes a pump and HEPA filter and, optionally, a UV sterilizer.
