Aquafina
Purified Water
Aquafina is PepsiCo’s purified-water brand, first sold in 1994 in the United States. It is produced by reverse osmosis purification of municipal water supply. Aquafina is not a natural mineral water or spring water; it carries no geographic source designation. The product has a significant market share in the US bottled water category.
