In 2006, PATH launched the Safe Water Project with funding from the Bill & Melinda Gates Foundation to investigate the potential for market-based approaches to providing clean water for low- and middle-income users with the ultimate goal of reducing disability, illness, and death related to unsafe water. PATH worked with product developers to design the C1 Common Interface—a standardized connection point between water filter devices and filter elements that allows interchangeability of parts between different household water filters. Manufacturers have designed water filter devices with this specification to enhance competition and choice for low-income households in developing settings. PATH's comprehensive guide to water filters with the C1 Common Interface includes product specifications, test results, advice on what to consider when comparing products, practical advice for the procurement and import of products, and manufacturers’ contact details.
