What is TDS and EC?
Total Dissolved Solids (TDS) refers to the amount of organic and inorganic materials dissolved in water. It includes metals, minerals, salts, and ions. 
While Electrical Conductivity (EC) refers to the ability of water to conduct an electric current.
Simply put: Higher EC = More salts

TDS and EC are interchangeable, providing insights into water purity.

How does this impacts my Health?
High TDS and EC doesn't necessarily mean unhealthy water, but substances like lead and copper can pose health hazards. Cooking with elevated TDS water may alter the taste of food, and cleaning challenges like water spots and buildup could be indicative of high TDS levels.
Importance of measuring Water quality
 Measuring TDS and EC is crucial as it provides valuable insights into your water quality, which, if inadequate, can potentially lead to health issues and affect everyday activities such as cooking and cleaning. A comprehensive understanding of TDS levels enables you to make informed choices regarding water quality improvement, allowing you to select the most suitable filtration system or other effective solutions
