High Alkaline Water Cartridge
Raise Your Water’s pH and Restore Natural Minerals
Looking to make your drinking water smoother and more balanced? The High Alkaline Water Cartridge from Gordon Water Systems adds beneficial minerals and slightly raises pH, creating water that tastes clean, refreshing, and naturally balanced.
It’s an easy way to enjoy high-quality drinking water every day—especially when paired with a Kinetico K5 Reverse Osmosis System.
What Is an Alkaline Cartridge?
An alkaline cartridge is a post-filter that restores essential minerals such as calcium and magnesium to purified water and raises pH toward a neutral-alkaline range. It’s commonly installed after a reverse osmosis (RO) or carbon filtration system to improve flavor and mouthfeel.
