    The Reverse Osmosis (RO) water systems can have as few as two stages and as high as eight stages. Choosing how many stages you need largely depends on the quality of water that needs to be purified. Usually, 5 stages are enough for a RO system , but you can go higher if you want more purity depending on the use you need to put the purified water too.
