There are many myths and false information about water. How do you know if the water you drink is safe? Are you getting all the nutrients you need from it? What are TDS & pH? Its time to know your water better.


Water is important to every cell, tissue, and organ in your body. The best way to stay hydrated: glug-glug-glug glasses of water throughout the day. Alkaline water is widely considered to be the healthiest and purest form naturally occurring water. To understand why, we need to understand what are TDS and pH

What are TDS & PH?

The “alkaline” in alkaline water refers to its pH level. The pH level is a number that measures how acidic or alkaline a substance is on a scale of 0 to 14. For example, something with a pH of 1 would be very acidic and something with a pH of 13 would be very alkaline.

What is the Ideal TDS Level of Drinking Water?

World Health Organization (WHO) report on TDS in drinking water points out that reliable data on possible health effects associated with TDS in drinking water is not available. The Bureau of Indian Standards (BIS) has set the acceptable limit of TDS in drinking water at 500 mg/L. However, the standard also mentions that in case no alternative source of drinking water is available, then this acceptable limit can be relaxed to 2,000 mg/L.

FIN’s ELIXIR series membranes maintain the optimum TDS & pH level to give you naturally fortified drinking water.

It is important to note that some of the dissolved minerals in water are useful for human health and therefore very low or zero TDS is also not recommended. Reducing the TDS level to a very low value also affects the pH level of the water, which BIS specifies should be in the range 6.5-8.5. Water with very low TDS will taste dull. There is no official lower limit, but TDS of at least 80 ppm is the accepted minimum level.
