Brand: KENT
Counter-top KENT with a UV-sterilised tank
Our editorial score
Very good — recommended
Renters and anyone who cannot drill walls, but still needs full high-TDS RO purification.
The Pearl is the Grand Plus's engineering in a counter-top body, plus one genuinely valuable addition: a UV lamp inside the storage tank. Most purifiers sterilise water on the way in and then let it sit in a warm plastic tank for hours, which is exactly how biofilm forms. Keeping the tank itself under UV is the right answer to a real problem, particularly in humid coastal cities.
The trade-off is space. Indian kitchen counters are the most contested real estate in the house, and this unit occupies a meaningful chunk of it. If you can drill a wall, the Grand Plus gives you more tank for less money. If you are renting, the Pearl is worth the premium.
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.

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.
