Cellulose filters were dipped and padded with m‐aramid dissolved in N,N‐dimethylacetamide followed by coagulation in distilled water. The coated filters were then chlorinated in a hypochlorite solution. The liquid permeability of the m‐aramid‐coated cellulose filters was examined. The resulting chlorinated and unchlorinated filters were assessed for their ability to disinfect contaminated water. The chlorinated m‐aramid‐coated cellulose filter produced 5 log reductions of Escherichia coli and Staphylococcus aureus, which was much higher than that observed on the unchlorinated m‐aramid‐coated cellulose filter. © 2013 Wiley Periodicals, Inc.
