In this era of competent materials and fabrication for air filtration the factor dictating the protection factor (ratio of concentration outside to inside the respirator) is unfiltered inward leakage. Respirator testing using humans is constrained by the requirement for advance approval of the protocol by a human use committee, by the diversity and caprices of the subjects used in testing, by factors such as fatigue and illness, and by health ...
The Air Force Research Laboratory (AFRL) has a broad interest in oxidizing-agent and photoactivated oxidizing agents that, when applied to textiles and other materials, will act as broad spectrum antimicrobials. For this project, poly(styrene-trimethylammonium triiodide) was incorporated into filtration devices to augment filtration. The overall goal of the project is to replace existing HEPA media with an antimicrobial membrane for both individual protection and collective protection devices. In this report ...
