Abstract : Tests were conducted to determine the effectiveness of Katadyn TM pocket Filters (KPF) to remove enteric bacteria (Klebsiella terrigena), protozoan cysts (Cryptosporidium parvum), and cyst simulants. Studies used the U.S. Environmental Protection Agency's Guide Standard and Protocol for Testing Microbiological Purifiers for guidance. Results showed that cysts were effectively removed by the filters over a typical 100 gallon use life of the ceramic filter candles used in the KPF. Bacterial removals were shown to also meet he criteria when improvements to end seal gaskets of the ceramic filters were made. Silver leaching tests indicated that EPA criteria were not always met; however,
