KENT vs Proven
Which Water Purifiers should you buy?
KENT Gold Optima Gravity Water Purifier (Non-Electric, UF Technology)
Proven Eleven Zinc Water Purifier (RO+UV+UF, Copper+Zinc)
Final Verdict: Tie
Why choose KENT?
The KENT Gold Optima is the honest budget answer for renters, hostels, or anyone with genuinely good municipal water who doesn't want to pay for RO purification they don't need. At ₹1,899 with no electricity or installation required, it is unmatched on price and portability — but the 3.6★ rating is the softest in our lineup, and it will not help at all with hard or high-TDS borewell water. Know your water source before buying this over an RO option.
Why choose Proven?
Re-verified 2026-09-18: this listing is genuinely titled "Proven Eleven Zinc," not "Nexon Aqua" as originally researched — and the real rating (3.7★) is meaningfully softer than what was previously claimed here (4.6★). It still matches the Pureplus on price range, tank size, and copper/zinc mineral enhancement, but honestly it is no longer a "promising alternative" pick — the Pureplus (4.6★, 9,548 reviews) is the clearly stronger choice at a similar price, and this entry is included mainly so readers searching for this exact real product find accurate information rather than a rebranded one.
