What it is

Reverse osmosis filtered water is purified water that has had most of the impurities, minerals, and contaminants removed through a process called reverse osmosis. In this process, water is forced under pressure through a semipermeable membrane that allows water molecules to pass but blocks larger molecules and ions.

Why it's used

Manufacturers use reverse osmosis filtered water as a base ingredient in beverages and other food products to ensure a clean, neutral taste and consistent quality. It is commonly found in bottled waters, juices, soft drinks, and processed foods where water is a primary component.

Health notes

Reverse osmosis filtered water is generally considered safe for consumption. The U.S. Food and Drug Administration (FDA) does not specifically regulate filtered water as a food additive, but it falls under general food safety regulations. International bodies like the World Health Organization (WHO) have established guidelines for drinking water quality, which this process aims to meet. No significant health concerns are associated with consuming water purified by reverse osmosis at typical intake levels.
