Reverse osmosis. Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water.
If you are gravely concerned with the pH of your water, you can use a mineralizing filter to neutralize your water. While RO water may be on the acidic side of neutral, its acidity does not compare to commonly consumed beverages such as soda and orange juice.
