The short answer

Best Premium / Best Hot Water: AO Smith Z9 Green RO — ₹33,990. Premium kitchens, high-TDS or brackish supply, and households that drink a lot of tea and coffee.
Best Overall: KENT Grand Plus — ₹16,499. Families on borewell, tanker or high-TDS municipal supply who want the safest all-round choice.
Best Tank Hygiene: LG PuriCare WW182EP — ₹31,990. Hygiene-focused buyers, humid coastal cities, and anyone who has ever opened a purifier tank and been unpleasantly surprised.
Best Service Network: Aquaguard Delight NXT — ₹17,990. Buyers who value service reliability and compact design over maximum tank capacity.
Before you buy anything: measure your TDS with a ₹300 meter. Under 200 ppm you need UV+UF, not RO — buying RO anyway wastes money, minerals and thousands of litres of water a year.

India does not have one water problem, it has several — and that is why most 'best water purifier' lists are useless. A ranking that puts the same RO unit at number one for a reader in Kochi (soft municipal supply, 120 ppm) and a reader in Jodhpur (brackish groundwater, 1,600 ppm) is not giving advice to either of them.

So we start from the water. Below is our overall ranking, but the more useful thing on this page is the set of specific lists underneath it: by technology, by water problem, by budget. If your supply is treated municipal water under 200 ppm, the correct recommendation is a ₹2,800 gravity purifier or a UV+UF unit — not a ₹20,000 RO that will strip your minerals and waste 16,000 litres a year solving a problem you do not have.

One more thing we weight heavily and most reviews ignore: whether anyone will service the thing. In this category the hardware is largely commoditised and the failure mode is almost never the membrane — it is a technician who never turns up. That is why KENT and Aquaguard keep appearing near the top of our tier-3 recommendations even where their specifications are not the best on paper, and why we tell you to phone customer care with your pin code before you order.

Frequently asked questions

Which is the best water purifier in India for home use?

For most homes on groundwater or blended supply, the KENT Grand Plus (around ₹16,499) or Aquaguard Delight NXT (around ₹17,990). Both handle input TDS up to 2,000 ppm, include a TDS controller and have the strongest service networks in India. Choose the KENT for a larger 9-litre tank and better water recovery; the Aquaguard for a much more compact unit and direct company service. If your TDS is under 200 ppm, buy a UV+UF purifier instead.

Which water purifier is best for high TDS water?

For TDS up to 2,000 ppm, the KENT Grand Plus, Aquaguard Delight NXT and Pureit Copper+ RO are all rated appropriately. Above 1,500 ppm, the AO Smith Z9 Green RO is the strongest domestic option with a 3,000 ppm input rating. Above 2,000 ppm, get a laboratory analysis first — water that concentrated often also carries hardness or fluoride needing specific pre-treatment.

What is the price of a good water purifier in India?

₹1,500-3,000 buys a genuine gravity UF purifier, which is the correct choice for treated supply under 200 ppm. ₹9,000-15,000 buys entry-level RO+UV. ₹15,000-20,000 is the mainstream sweet spot with a TDS controller and a decent tank. ₹25,000-35,000 buys hot water, a stainless-steel tank or a 3,000 ppm input rating. Spending beyond what your water requires buys nothing.

Is RO or UV better for a home water purifier?

It depends entirely on your TDS. Above 300 ppm you need RO, because it is the only technology that reduces dissolved solids, heavy metals, arsenic and fluoride. Below 200 ppm, UV+UF is better: it kills microbes, retains beneficial minerals, wastes no water and costs less to run. Buy RO regardless of TDS if your area has any known arsenic, fluoride or nitrate problem.

How much does water purifier maintenance cost per year?

Budget ₹2,500-₹4,500 a year for a domestic RO including all consumables and two to three service visits. Copper, alkaline and hot-water models cost more. The critical discipline is changing the cheap sediment and carbon pre-filters on schedule — an exhausted carbon filter lets chlorine through and destroys the far more expensive RO membrane.

Which water purifier brand has the best service in India?

Eureka Forbes (Aquaguard and Aquasure) has the deepest direct-technician network, followed closely by KENT. Both reach tier-3 and tier-4 towns properly. Native by Urban Company offers the best service experience where it operates, because servicing is app-booked at published fixed prices. AO Smith, Coway and Levoit are excellent products with genuinely thinner service reach outside metros — verify your pin code before ordering.
