The science
What the filter does to the water
Tap water is usually close to neutral, around pH 7, with whatever mineral content your municipality happens to deliver. As water passes through this cartridge, three things happen in sequence.
First, activated carbon reduces chlorine taste and odor, the flat, faintly chemical note most tap water carries. Second, an ion exchange stage adds calcium and magnesium, the same minerals that give good spring water its taste. Third, a magnesium mineral bed raises pH into the alkaline range.
The studies below are peer-reviewed research on alkaline and mineral drinking water in general. They are listed for reading, with links to the original publications. They are not claims about this filter.

This page describes what the filter does to water: it reduces chlorine taste and odor, adds calcium and magnesium, and raises pH. It makes no health claims. Talk to your doctor about your own hydration and health.
