Ceramic water filters coated with silver nanoparticles are effective at treating contaminated drinking water in rural communities. A study tested locally produced ceramic filters, one coated with silver nanoparticles and one not coated, on microbial pathogens in water from a stream in Iwo, Nigeria. Results showed that both filters removed 100% of tested pathogens like Salmonella, E. coli, and parasites after filtration. Physicochemical properties of the water like turbidity, conductivity and coliform levels also saw over 90% reductions on average with both filter types during the 240 minute testing period. The silver nanoparticle coated filter performed slightly better at removing contaminants. Therefore, locally produced ceramic filters, especially when coated with silver, can provide a low-cost way
