This is true, water that filters through the Black Berkey™ elements tends to be more basic than before being filtered. Its pH increases. And in reality, this is a good thing... Pathogenic bacteria and viruses thrive in acidic environments and struggle to survive in alkaline environments. The higher the pH, the greater the alkalinity.

However, it is important to remember that the final pH level of the treated water can depend on other factors, like the pH level of the water before being filtered.
