TDS stands for Total Dissolved Solids — a measurement of all organic and inorganic substances dissolved in water. This includes minerals (calcium, magnesium, sodium), salts, metals, and various ions.
What is the ideal TDS for drinking water?
According to WHO and BIS standards, the ideal TDS for drinking water is 80–150 ppm. DrowWater maintains exactly this range in all our deliveries — giving you the perfect balance of mineral content and purity.
Is low TDS water safe?
Water with very low TDS (below 50 ppm) may lack essential minerals and can taste flat. RO water at 80–150 ppm strikes the perfect balance between purity and mineral content.
Is high TDS water dangerous?
Yes. TDS above 500 ppm indicates excessive minerals and possible contaminants. Above 900 ppm, the water is generally considered unsafe for drinking and can cause kidney issues, digestive problems, and other health concerns.
How to test TDS at home?
A TDS meter costs just ₹200–500 on Amazon or local stores. Simply dip it in water and read the PPM value. Delhi tap water often reads 400–800 ppm — well above the safe limit.
