Antimicrobial Efficiency of Iodinated Individual Protection Filters

Abstract

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 we investigate the microbial efficacy of an iodinated Clip-On prototype and a commercial-off-the-shelf (COTS) carbon-HEPA aerosol canister. Our data indicate that the Clip-On, in series with a COTS canister provides an additional 2 logs of attenuation vs. a standard COTS canister when challenged with MS2 coliphage.
