#27 Unilever and the Quest for Safe Water: The Pureit Innovation Story

DescriptionAccess to safe drinking water remains one of the world’s most urgent public health challenges. In this episode, we examine how Unilever attempted to tackle this crisis through Pureit, a low-cost household water purifier designed for low-income and underserved communities.Originally developed in India, Pureit was engineered to deliver water “as safe as boiled water” without electricity, plumbing, or complex maintenance. We explore how Unilever combined product innovation, behavior-change marketing, and a razor-and-blades business model to make clean water accessible to millions—while still operating as a for-profit venture.The episode traces Pureit’s journey from a Base-of-the-Pyramid innovation to a global brand operating across Asia, Africa, Latin America, and even developed markets. We also unpack the challenges Unilever faced: consumer education, filter replacement compliance, competition, affordability, and the tension between social impact and commercial sustainability.Ultimately, this case raises a bigger question: what role should multinational corporations play in delivering essential services like clean water? Pureit offers a compelling—and cautionary—example of how business can contribute to public health at scale.KeywordsUnilever, Pureit, Safe Drinking Water, Public Health Innovation, Base of the Pyramid (BoP), Inclusive Business, Water Purification, Social Impact, Corporate Social Innovation, Sustainable Development Goals (SDG 6), Emerging Markets, Health and Hygiene
