How much TDS in Water is Safe for Drinking

How much TDS in Water is Safe for Drinking?

In the world of water quality, Total Dissolved Solids (TDS) is a key factor. TDS shows how much stuff is dissolved in water, including minerals, salts, metals, ions, and other compounds. This guide aims to explain TDS levels, focusing on a crucial question: What TDS level is safe for drinking water? We’ll also explore whether a TDS level of 25 is genuinely safe for drinking. Knowing about TDS is important to check if water is pure and okay to drink, following the rules of water authorities.

What is TDS in Water?

Defining TDS: Total Dissolved Solids (TDS) measures both the inorganic and organic stuff in water. It includes minerals, salts, metals, ions, and other compounds. TDS levels help determine water quality and taste, crucial for deciding if water is safe to drink.

What is the Best TDS Level for Drinking Water?

The right TDS level for drinking water is a bit debated. Water with very low or high TDS may not be good to drink. Usually, a TDS level of 150 to 300 parts per million (ppm) is seen as good for drinking. But remember, TDS alone doesn’t tell everything about water quality.

Understanding Safe Ranges:

Water with less than 50 ppm TDS might taste plain, while more than 1,000 ppm might taste bad. Too low TDS may mean water without enough minerals, and too high could mean too many minerals or contamination. We need to follow strict water quality standards.

Is 25 TDS in Water Safe for Drinking?

A TDS level of 25 is low. It might be safe to drink, but it may lack essential minerals for taste and health. Safety also depends on where the water comes from and how it’s treated, following global water quality rules.

Considering the Source: Where the water comes from is crucial. If water with 25 TDS is from a good source, it’s likely safe. But if it’s from an unsure or untreated source, it might not follow water safety rules. Still, 25 TDS water might lack needed minerals and be not good to drink.

The Role of RO Water Purifiers:

RO Purification: To make sure water is safe to drink, no matter the initial TDS level, we can use a Reverse Osmosis (RO) water purifier. RO systems are good at removing bad stuff, giving us clean and safe water, following water treatment rules.

RO on Rent- For those worried about TDS levels, renting an RO water purifier is a cost-effective solution. This gives access to safe water without a big upfront cost, following water quality guidelines.


In the quest for safe drinking water, TDS levels help a lot, following water rules. Water with 25 TDS might be okay to drink, but we must think about where it comes from and how it’s treated, following strict water quality standards. Using an RO water purifier, bought or rented, can make sure your drinking water is safe. Remember, for your health, water quality is vital, and making smart choices helps keep you safe, just like global water safety efforts say.
