Top Pros
- ✓910 reviews at a solid 4.0★ — a well-tested non-RO option
- ✓UV+UF retains natural minerals that RO membranes strip out, a genuine advantage for households already on good-quality water
Watch Out For
- ✕Explicitly not suitable for borewell or tanker water — municipal supply with TDS below 200 only
“For households that specifically have good, low-TDS municipal water supply, the AO Smith X2 skips RO's water wastage and mineral-stripping entirely — a genuine advantage for the right household. But the "not suitable for borewell or tanker water, TDS below 200 only" restriction is a hard limit, not a soft recommendation — check your actual water TDS before choosing this over an RO purifier.”

Our Verdict
Pros
- ✓910 reviews at a solid 4.0★ — a well-tested non-RO option
- ✓UV+UF retains natural minerals that RO membranes strip out, a genuine advantage for households already on good-quality water
- ✓No RO membrane means no wastewater rejection — every litre of input water becomes usable output
- ✓Established AO Smith brand backing
Cons
- ✗Explicitly not suitable for borewell or tanker water — municipal supply with TDS below 200 only
- ✗Does not reduce TDS or remove dissolved salts the way RO purifiers do
- ✗A meaningful restriction that rules this out for the large share of Indian households without reliably low-TDS municipal water
Bottom Line: For households that specifically have good, low-TDS municipal water supply, the AO Smith X2 skips RO's water wastage and mineral-stripping entirely — a genuine advantage for the right household. But the "not suitable for borewell or tanker water, TDS below 200 only" restriction is a hard limit, not a soft recommendation — check your actual water TDS before choosing this over an RO purifier.
Expert Analysis
🏗️ Design & Build
A wall-mounted UV+UF unit without an RO membrane stage, simpler internally than the RO purifiers elsewhere in our lineup since there's no membrane or reject-water plumbing to manage.
⚡ Performance
UV sterilises biological contaminants while UF (ultrafiltration) removes suspended particles and larger contaminants — effective against bacteria and cysts, but unable to remove dissolved salts or reduce TDS the way an RO membrane does.
🥘 Indian Kitchen Fit
This directly targets the segment of Indian households with genuinely good municipal water supply, where RO's TDS reduction is unnecessary and its ~50% water wastage during purification is a real downside. For borewell or tanker-water households, this is simply the wrong tool — check your water source before buying.
💰 Value for Money
At ₹10,599, this costs about the same as mid-tier RO purifiers, but the value proposition is entirely different — you're paying for retained minerals and zero water wastage, not TDS reduction. Confirm your municipal water's TDS is genuinely below 200 (a home TDS meter costs under ₹500) before choosing this over an RO alternative.
What Buyers Say
Top Praise
"Reviewers on good municipal water report noticeably better taste (retained minerals) compared to their previous RO purifiers, plus no water wastage."
Top Complaint
"A meaningful number of reviewers who bought this without checking their water source report poor performance on borewell/high-TDS water — consistent with the product's stated limitations."

Care & Maintenance
Test your water TDS with a home meter before and periodically after purchase to confirm this remains the right purifier type for your supply
Replace UV lamp and UF membrane on schedule — UV effectiveness particularly degrades gradually and isn't always obvious from water taste alone
If your water source changes (e.g., you move, or municipal supply quality drops), re-evaluate whether an RO purifier is now more appropriate

Pureit (HUL)
Pureit Classic 23L Gravity Based Water Purifier
The Pureit Classic is the better-rated, larger-capacity alternative to the cheapest gravity purifier in our lineup — 23L of storage (versus 10L on the KENT Gold Optima) and a stronger 4.2★ rating, for ₹1,100 more. If you specifically want a big non-electric tank and can live with the manual-refill weight, this is the stronger of our two gravity picks.
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.
KENT
KENT Grand RO Water Purifier (RO+UF+TDS Control+UV LED Tank)
The KENT Grand RO is the safe, well-proven default for Indian homes — the single most recognised name in the category, a genuinely strong 4.6★ rating from over a thousand reviews, and India's largest RO service network behind it. If you just want a purifier that works and gets serviced quickly when it doesn't, start here.
