Membership Mark Purified Water

Purified water is a generic product category produced by hundreds of different brands around the world. Unlike mineral or spring water, purified water undergoes rigorous filtration and treatment processes such as reverse osmosis, distillation, or deionization to remove impurities and contaminants. This means that the 'origin' of the water is less tied to a specific geographic source and more to purification standards, often adhering to the United States Pharmacopeia (USP) or local health regulations.

Large global corporations like Nestlé, Coca-Cola, and PepsiCo dominate the commercial purified water market with brands like Aquafina and Dasani. These products are typically manufactured locally in various countries to minimize transportation costs and environmental impact, using municipal water sources that are then refined through proprietary purification systems and, at times, remineralized to enhance flavor.
