Brand: KENT
High-throughput KENT for large families and small offices
Our editorial score
Very good — recommended
Large households and small office pantries that need volume more than features.
The Prime TC is the value pick within KENT's own range: you keep the RO+UV+UF+TDS stack and the 20 litre/hour throughput, and you give up the water-recovery technology. If your supply is metered or tanker-fed, that omission matters and you should pay up for the Grand Plus. If you are on reliable municipal supply, the Prime TC does the same job for less.
The detachable tank deserves a specific mention. Almost every purifier in this price band has a sealed tank that can never be properly cleaned, and after two years in Indian ambient temperatures that is where the hygiene problem actually lives. Being able to take it off and scrub it is a real, practical advantage.
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 →Strong transparency. This is separate from our review score above — it measures how well documented, how supportable and how expensive to own this water purifier is, scored on 6 of 7 axes by formula, with no manual override. See the methodology.

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.
