Abstract
The invention utilizes a chemical/biological hood with a filter-blower system that is attached to the chemical/biological hood. The filter-blower system provides overpressure to the hood only. The hood is fitted to or attached to a chemical/biological mask. Overpressure created by the filter-blower around the mask is created and is independent of the wearer's respiration so that over-breathing of the positive pressure is not possible. Typically this system would be available as a hood capable of providing enhanced protection. However, the filter-blower and hood system could be integrated with the mask. Cinching or sealing the hood at the neck can improve overpressure performance.
