As an amazingly simple and effective way to control biological contamination in drinking water at the household level, the all-natural MadiDrop prevents water- borne illness and disease — without changing the taste and smell of the water. The MadiDrop is an engineered ceramic tablet embedded with silver. Once in water, it consistently releases precise amounts of silver ions, which are well known for their antimicrobial properties. Used in a vast array of products, silver ions are highly effective at eliminating waterborne pathogens such as E. coli. MadiDrops have already provided over 30 million liters of safe water to families in rural, peri-urban and urban environments. From water sources ranging from rivers to shallow wells to substandard municipal systems, the MadiDrop has provided freedom through the power of safe drinking water – freedom from waterborne illness and disease, daily chemical interventions, and laborious fuel required disinfection techniques.
