Brand: KENT
Hidden under the counter, copper-enriched at the tap
Our editorial score
Very good — recommended
Modular kitchens where the purifier must be invisible.
Under-sink is the right answer for a modular kitchen and the wrong answer for a retrofit into a cramped cabinet already full of plumbing. The KENT Supreme Copper does the job well: same 2,000 ppm RO stack as the wall-mounted range, copper enrichment, and a dedicated faucet at the sink.
Think carefully about servicing. Every filter change means clearing out the cabinet, and you lose the at-a-glance indicators that tell you something is wrong. If you are planning a new kitchen, specify it now and leave proper access. If you are retrofitting, measure first — twice.
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.
Purifiers for high-TDS supply →Water wastage matters to you
The brand does not publish a recovery figure, so there is no way to know how many litres go to drain per litre purified. Only 2 of the 26 water purifiers we track publish this at all.
High-recovery purifiers →Low running cost is a priority
Consumables and routine service run about ₹4,200 a year, which is in the most expensive quarter of the water purifiers we track. Over five years that puts total ownership near ₹46,990.

Specifications are from manufacturer literature and were checked at the last price-verification date. Brands occasionally revise stage counts, tank sizes and warranty terms without changing the model name — confirm against the current listing before purchasing.
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.
