The carbon in the filters is activated, which means that it has a high surface area and is very porous. This allows it to trap a wide range of contaminants, including chlorine, heavy metals, and other impurities.

TDS stands for Total Dissolved Solids and is measured in parts per million (ppm) or parts per billion (ppb). It’s a measure of the water’s organic and inorganic content including minerals and nutrients.

Natural water will have a TDS reading from minerals and nutrients picked up from the rocks and ground it flows through. It’s generally accepted that 300 ppm is a good mineral content. We purposely do not bring our TDS to zero, because we’re all about preserving the natural vitamins and minerals your body needs
