RO water has a pH between 6 and 7, but no matter what the pH of the water you consume, as it passes through the cell wall, it instantly becomes the pH of your body. - Water is not a significant source of minerals and the pH of the water makes no difference.

What is water ultrafiltration?

Ultrafiltration (UF) is a water purification process in which water is forced through a semipermeable membrane.
