The default recommendation for Indian borewell water
Our editorial score
Outstanding — a top pick in its class
Families on borewell, tanker or high-TDS municipal supply who want the safest all-round choice.
If someone asks for one water purifier recommendation without telling me anything about their water, this is the answer. The Grand Plus is not the prettiest or the cheapest unit in this list, but it is the most consistently correct one: an RO membrane rated to 2,000 ppm input, UV and UF stages behind it, and a TDS controller so that low-TDS supply does not get stripped to tasteless.
The two features that actually justify the price over cheaper RO units are Save Water technology and the service package. Legacy RO designs throw away three litres for every litre they purify. KENT's recovery design roughly halves that, which in a metro paying for tankers is a real line item, not a green talking point. And the three years of free service matters more than any spec sheet — in this category the failure mode is almost never the hardware, it is a technician who never turns up.
Where it loses points: the design is unapologetically appliance-grade, the footprint is large, and there is no hot-water dispensing. If your water tests below 300 ppm, you are buying capability you will never use — look at a UV+UF unit instead and save both money and water.
Every condition below is derived from this product's published specifications and from how it compares with the water purifiers we track — so you can check each one against your own room, supply or budget rather than take our word for it.
Your supply runs above 2,000 ppm TDS
The membrane is rated to 2,000 ppm. Feed it more and it will not fail dramatically — it will die early and quietly, and you will be buying membranes annually. Check your worst-season reading, not your average one.

The brand that made 'RO' a household word in India. KENT's mineral-ROTM positioning — RO plus UV plus UF with a TDS controller — is still the template most competitors follow. Strongest on purification hardware and spares availability; weakest on design, where the white-and-blue plastic aesthetic has aged.
Themes we see consistently in owner feedback for this model. These are illustrative of reported experience rather than a statistical sample — read the current marketplace reviews too, and weight recent ones most heavily.
Our borewell tested at 1,150 ppm and every cheaper purifier we tried gave brackish water. Output now measures around 90 ppm on my own TDS pen. Installation took an hour and the technician actually explained the TDS controller setting.
Works exactly as promised and the free service visits have been on time. Only complaint is the size — plan your wall space before it arrives, it is much larger in person than in photos.
