What Is an RO Water Filtration System?
An RO system (short for reverse osmosis) is a type of water filtration system that uses a multi-stage process to remove impurities from your water. Unlike basic filters that only trap sediment or reduce chlorine, RO pushes water through a semi-permeable membrane that separates dissolved solids, minerals, chemicals, and other contaminants.
The result is clean, safe, great-tasting water that’s ideal for drinking, cooking, and even making coffee or baby formula. RO systems can be installed under a single sink for point-of-use filtration or set up as a whole-house RO system to provide purified water at every tap in your home.
