Member's Mark Purified Water

Member’s Mark is the premium private-label brand for Sam’s Club, a division of Walmart Inc. The brand was established to provide high-quality products ranging from fresh food to household essentials at a competitive price point. Member’s Mark Purified Water is sourced and bottled through a network of regional suppliers to minimize transportation costs and ensure freshness across the United States.

As a private label, the ultimate ownership resides with Walmart Inc., a global retail giant headquartered in Bentonville, Arkansas. The manufacturing process typically involves advanced filtration techniques like reverse osmosis or distillation, followed by remineralization for taste. Because Walmart utilizes various regional bottling partners, the exact factory location can vary depending on the point of sale, though it is predominantly produced within the United States for the North American market.
