Why is my Total Dissolved Solids (TDS) reading so high?

Jonah Flores Updated by Jonah Flores

A TDS metre measures the total dissolved solids in your water - this includes both healthy minerals (such as calcium and magnesium) and harmful substances (such as lead and chlorine). 

Santevia filters work to improve the quality of your drinking water by removing harmful contaminants and adding back essential minerals.

This means that the first stage of our filtration process reduces TDS by removing contaminants, while the second stage increases TDS by adding back beneficial minerals. The result is water that has a TDS that may be equal to or even higher than your tap water, yet free of harmful substances.

Determining the quality of the substances present in your drinking water can be a complex task. To accurately determine the quality of your drinking water, laboratory testing is necessary. 

Although TDS meters provide information on the concentration of substances in your water, they don’t not offer a complete picture of its quality.

How can I test the pH of my water?

The tap water where I live is considered "good quality". Why do I need a Santevia alkaline water filter?
