The ideal TDS level for drinking water is usually between 50 and 150 ppm, with up to 300 ppm still considered acceptable for daily use.
Not all water with TDS is unsafe. The key is keeping it within a safe range.
- Up to 300 mg/L – considered good for drinking
- 300 to 500 mg/L – acceptable
- Above 500 mg/L – not recommended for regular consumption
When TDS levels go beyond safe limits, the water may contain salts or other harmful substances that you don’t want. Being aware of the safe TDS level for drinking water helps you figure out if your current water is safe to drink or if it needs to be treated.
