What reverse osmosis water is
Reverse osmosis pushes water through a very fine membrane that holds back most of what's dissolved in it. What comes out is clean, crisp purified water that's great for drinking, coffee, tea, cooking, baby formula and pets.
Our purified water is the same water we start from for our alkaline water and our purified ice.
