What is the pH of RO purified water? Is it healthy for ...

The reverse osmosis filtration removes the alkaline mineral atoms from salt molecules, that’s why the water after being purified by an RO purifier does become acidic. For example, from the molecule of carbon bicarbonate, the calcium atom is removed, To produce carbonic acid, soda water is made by dissolving carbon dioxide (CO2) in water (H2O).
