Quick Answer: The Best Pick
For high TDS borewell water in India, you need an RO + UV + MTDS purifier. The Kent Supreme or AO Smith Z9 are top choices because they offer superior filtration and reliable service networks across major Indian cities.
Why Borewell Water Needs RO
Borewell water in many parts of India (like Bangalore, Hyderabad, or Delhi-NCR) is "hard" and contains high levels of Total Dissolved Solids (TDS). This includes calcium, magnesium, and sometimes heavy metals like lead or arsenic.
Standard UV purifiers only kill bacteria; they cannot remove dissolved salts. Only RO (Reverse Osmosis) can reduce the TDS to a safe, palatable level.
RO+UV Technology Explained
Modern purifiers use multiple stages. RO handles the salts, while UV acts as a secondary shield against viruses. A TDS controller (MTDS) allows you to adjust the taste so the water doesn't feel "flat" or too acidic.
