Experiments conducted with commercial point-of-use precoat carbon filters showed that these filters can significantly and consistently reduce the heterotrophic plate count (HPC), coliforms, enteric viruses, and protozoan cysts in water. Although the effect of silver in the precoat filters on HPC organisms was inconclusive, the presence of silver dramatically reduced coliform levels. The antimicrobial effect of copper in these filters was similar to, but much less than, that of silver. Includes 32 references, tables, figures.
