Foods - Water - Reverse Osmosis (RO) Water

Reverse osmosis water involves the pressurized passing of water through one or more membranes. The filters are typically measured in microns and can block organisms, heavy metals, and dissolved solids. The water may also pass through an ultraviolet (UV) filter to further ensure purity. RO water may have some minerals and trace elements present, depending on the type of filter(s) used.
