- • Budget buyers wanting copper/zinc-enhanced RO for borewell water at the lowest available price

- • Buyers who prioritise rating or the largest possible proof base — see Pureplus instead

Top Pros
- ✓Copper + Zinc mineral enhancement at a genuinely low ₹4,149 price
- ✓12L storage tank, same as the pricier Pureplus option
Watch Out For
- ✕3.7★ is one of the softer ratings in this entire category — genuinely below every other RO purifier we track except this one
“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.”

Expert Analysis
🏗️ Design & Build
A compact wall-mounted 12-stage purification unit with a 12L tank, comparable in scale to the Pureplus. Standard budget-tier build quality — functional rather than premium finish.
⚡ Performance
RO + UV + UF core purification with copper and zinc mineral enhancement and a TDS Adjuster for tuning mineral retention. The purification stack is genuinely comparable to the Pureplus on paper, but the live review base rates the real-world experience meaningfully lower.
🥘 Indian Kitchen Fit
Explicitly built and marketed for borewell water — a large share of Indian households outside major municipal-supply areas — with 12L storage suited to a full day's household water needs without frequent refill cycles.
💰 Value for Money
At ₹4,149, this is now cheaper than the Pureplus, but with a materially softer 3.7★ rating (versus Pureplus's 4.6★) from a smaller review base (626 vs 9,548). The lower price alone doesn't make this the better buy — the Pureplus remains the stronger pick on proof and rating; this is only worth considering if Pureplus is genuinely unavailable or you specifically want the absolute lowest price in this feature tier.
What Buyers Say
Top Praise
"Reviewers who are satisfied cite the price relative to competitors offering similar copper/zinc mineral-enhancement specs."
Top Complaint
"The softer 3.7★ rating reflects a real, meaningful share of less-satisfied reviewers compared to this category's stronger-rated options — worth reading recent reviews directly before buying."
Based on aggregated reviews from Amazon (3.7★) and Flipkart (3.6★)

Pureplus
Pureplus Zinc Copper Alkaline Hydrogen RO Water Purifier (12L)
At ₹5,499, the Pureplus is the standout value pick in this category — a genuinely massive 9,548-review base at 4.6★, mineral enhancement (zinc, copper, alkaline) that competitors charge ₹15,000+ for, and a 12L tank. The trade-off is a newer brand name with a thinner service network than KENT or Eureka Forbes, worth weighing if after-sales support matters more to you than upfront price.
Pureit (HUL)
Pureit Wave Plus RO Purifier + Mineral + UV
The Pureit Wave Plus is a solidly reasonable middle-of-the-road choice — a real 4.4★ rating from a healthy 804-review sample, HUL's corporate backing, and genuine water-saving credentials, without the standout price of the budget options or the mineral-enhancement features of pricier ones. A safe pick if you want a known name without going premium.
KENT
KENT Gold Optima Gravity Water Purifier (Non-Electric, UF Technology)
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.
