Know your Water

Understanding the quality and safety of the water you consume is fundamental to a healthy life. And it starts with knowing the basics that govern good and bad drinking water –  knowing its TDS, Hardness and how to test it.

What is TDS?

TDS stands for Total Dissolved Solids. It refers to the total concentration of all inorganic and organic substances that are dissolved in the water. These include minerals, salts, metals, and other compounds. It is an important indicator of water quality. High TDS levels in drinking water can affect its taste, appearance, and overall suitability for consumption.

What is Hard Water?

Water that contains high levels of dissolved minerals, primarily calcium and magnesium ions is Hard Water. These minerals are picked up as water flows through rock and soil. The higher mineral content in hard water can lead to issues such as scaling in pipes and appliances, as well as reduced lathering of soaps and detergents.

Test your Water

It is now super easy to test the quality of your drinking water for its TDS score and hardness. The Government of India, under its Jal Jeevan Mission, has made Water Quality Labs accessible to general public. Simply search with your locality to find the Water Lab nearest to you and get it checked at a very nominal cost.

If you have municipal water supply or water with TDS less than 500, Doulton might be the perfect water filter for you
