Kent Ro is really very appreciating water purifier system. I have installed it in my home as well as in my office. You can make the PH level according to you by just asking their service providers. Moreover the water quality increases as it removes the bacteria. The solid proof of this is my younger brother used to get infected easily and get stomach pain, but from last 6 months he has not faced the issue This is because we use Kent ro water for drinking and cooking.
