Best RO Water Purifier in India (2026): The True Cost of Every RO Model, Filter by Filter
We compared 11 RO water purifiers sold in India across published specs, Amazon listing data, filter-cost transparency, and review volume. Three picks stood out for different budgets and water types.
If you just want the shortcut: Atomberg Intellon is the best overall pick for most Indian homes, Livpure GLO PRO++ is the strongest value under ₹10,000, and Native M2 Pro is the premium pick if you want app-based TDS tracking and service-bundled economics.
Different picks depending on your water supply
- If your supply is municipal or low TDS and you are on a tight budget, the Livpure GLO PRO++ covers the essentials with a complete RO + UV + UF chain.
- If your TDS fluctuates between municipal and borewell water, the adaptive mode on the Atomberg Intellon is the safest single choice, and it is the only pick that publishes an annual filter cost.
- If you want app-based TDS tracking and a service plan that bundles filter changes, the Native M2 Pro is the premium pick for connected, high-TDS homes.
The running-cost and water-wastage table: all 11 RO models
This is the table nobody else publishes. Every RO purifier hides two running costs: the yearly filter bill and the water it sends down the drain as reject. Prices are bands as of July 2026. Ratings are cited with their Amazon review counts. “Not published” means neither the manufacturer nor the marketplace listing provides the figure.
| Model | Price band (Jul 2026) | Rating (count) | Storage | Max input TDS | Water recovery / savings | Filter cost / year | Cost disclosure | Warranty |
|---|---|---|---|---|---|---|---|---|
| KENT Supreme Plus | ₹15,599 to ₹26,500 | 4.1★ (15,541) | 8 L | Not published (mfr: borewell/high-TDS) | Not published | Not published (intervals only) | Partial | 1 yr + 3 yr extended service |
| Livpure GLO PRO++ | ₹8,929 | 4.1★ (14,866) | 7 L | 2,000 ppm | Not published | Not published | Not published | 1 yr |
| Aqua D Pure 4-in-1 Copper | ₹5,248 | 4.2★ (12,663) | 12 L | Not published | Not published | Kit ₹1,500 (interval not published) | Partial | Not published |
| Aquaguard Sure Delight NXT | ₹10,999 | 4.1★ (8,366) | 6 L | 0 to 2,000 mg/L | Up to 60% savings (claim) | Not published (cartridge up to 1 yr) | Partial | 1 yr + free service |
| KENT Grand | ₹12,899 to ₹19,500 | 4.4★ (7,572) | 8 L | 2,000 ppm | Not published | Not published (intervals only) | Partial | 1 yr + free service |
| Native M1 | ₹15,999 to ₹20,999 | 4.4★ (6,790) | 8 L | Not published | Not published | ₹2,500/yr (₹5,000 per 2 yr) | Full | 2 yr unconditional |
| Pureit Eco Water Saver | ₹11,999 to ₹24,850 | 4.2★ (2,797) | 10 L | 2,000 ppm | Up to 60% savings (claim) | Not published | Not published | 1 yr |
| Native M2 Pro | ₹19,499 to ₹28,999 | 4.4★ (1,820) | 8 L | 300 ppm (caveat) | Not published | ₹2,500/yr (₹5,000 per 2 yr) | Full | 2 yr |
| Havells Gracia FAB | ₹21,989 to ₹32,549 | 4.1★ (3,631) | 6.8 L | 2,000 ppm | Not published | Not published (AMC from ₹2,781/yr) | Not published | 1 yr |
| AO Smith Z2+ Luxe | ₹21,599 to ₹27,490 | 4.1★ (1,527) | 5 L | 2,000 ppm | Up to 30% recovery (mfr) | Not published | Not published | 1 yr incl. membrane |
| Atomberg Intellon | ₹17,989 to ₹25,999 | 4.1★ (1,597) | 8 L | 1,500 ppm | Adaptive: skips RO when TDS safe | ₹0 first 2 yr, then ~₹1,200 to ₹1,500/yr | Full | 2 yr all-inclusive |
Running-cost disclosure tally: of 11 RO models, only 3 publish a computable annual filter cost (Full), 4 publish intervals or a kit price but not enough to compute ₹/yr (Partial), and 4 publish nothing. Water-recovery tally: only 3 publish a recovery percentage or savings claim, and 1 (Atomberg) uses an adaptive design that avoids reject water when TDS is safe. That split is the most useful thing this page can tell you.
How we research RO water purifiers
HomeVerdicts is a research-aggregation site. We do not run a lab and we do not measure TDS reduction ourselves. Instead, we pull published manufacturer specs, Amazon listing data, and review volume, then compare models on the same axes so you can see where the trade-offs are.
What we compared
For this guide we looked at 11 RO water purifiers sold in India. We scored each one on:
- Purification stages: RO, UV, UF, mineraliser, and whether the unit adapts based on input TDS.
- Tank capacity: useful for families and for power-cut resilience.
- Filter cost transparency: whether the brand publishes a yearly filter replacement cost. Only 3 of the 11 models we compared do this.
- Review volume and rating: pulled from the Amazon listing at the time of writing.
- Price band: list price and the typical Amazon selling price.
Why filter cost matters more than sticker price
An RO purifier’s true cost is the sticker price plus filter replacements over 3 to 5 years. A unit that is ₹4,000 cheaper up front can end up costing more if its cartridges are expensive or if the brand does not publish replacement pricing at all. That is why we weight published filter cost heavily in the overall ranking.
Who each pick is for
If your supply TDS fluctuates between municipal and borewell, the adaptive mode on the Atomberg Intellon is the safest single choice. If you are on a strict budget and your supply is mostly municipal, the Livpure GLO PRO++ covers the essentials. If you want app-based TDS tracking and a service plan that bundles filter changes, the Native M2 Pro is the premium pick.
Atomberg Intellon
The Atomberg Intellon is our best overall pick because it is the only model in our shortlist that publishes an annual filter cost and offers an adaptive purification mode. When input TDS is already within a safe range, the unit can switch off the RO stage and rely on UF + UV, which extends membrane life and reduces wastewater.
Manufacturer specs list an 8 L storage tank, RO + UF + UV purification, and an adaptive mode that responds to input TDS. The Amazon listing at the time of writing shows a 4.1-star rating across 1,597 ratings, with a selling price band of ₹17,989 to ₹25,999 depending on colour and offers.
Specifications and filter data
| Purification stages | RO + UF + UV (adaptive) |
| Tank capacity | 8 L |
| Max input TDS | 1,500 ppm |
| Annual filter cost | ₹0 first 2 yr, then ₹1,200 to ₹1,500/yr |
| Adaptive mode | Yes, switches off RO when TDS is safe |
| Amazon rating | 4.1★ across 1,597 ratings |
| Warranty | 2 yr all-inclusive (covers consumables) |
| Price band | ₹17,989 to ₹25,999 |
Why it ranks first
Across the 11 models we compared, only 3 publish a computable yearly filter cost. The Intellon is one of them, and it is the only one of the three that also offers an adaptive mode. For most Indian homes where supply TDS is not constant, that combination is the most defensible single pick.
Where it is weaker
The Intellon sits in the mid-to-upper price band. If your supply is consistently low-TDS municipal water and you do not need adaptive mode, the Livpure GLO PRO++ below covers the same essentials for roughly half the entry price.
Livpure GLO PRO++
The Livpure GLO PRO++ is our best value pick. It is the lowest entry price in the shortlist and still includes a complete RO + UV + UF chain, which not every sub-₹10,000 RO unit does. Manufacturer specs list RO + UV + UF purification and a 7 L storage tank.
The Amazon listing at the time of writing shows a selling price from ₹8,929 against an MRP of ₹15,500. The listing shows a 4.1-star rating across 14,866 ratings.
Specifications and filter data
| Purification stages | RO + UV + UF |
| Tank capacity | 7 L |
| Max input TDS | 2,000 ppm (Amazon) |
| Annual filter cost | Not published by manufacturer |
| Adaptive mode | No |
| Amazon rating | 4.1★ across 14,866 ratings |
| Warranty | 1 yr |
| Price band | From ₹8,929 (MRP ₹15,500) |
Why it ranks second
For buyers on a strict budget whose supply is mostly municipal, the GLO PRO++ covers the essentials at roughly half the entry price of the Intellon. A complete RO + UV + UF chain at this price is a real plus.
The honest con
Livpure does not publish a yearly filter replacement cost. That makes the long-run running cost harder to compare against the Intellon and the Native M2 Pro, both of which do publish filter economics. If filter-cost transparency matters to you, treat the GLO PRO++ as the budget pick rather than the long-run cheapest pick.
Native M2 Pro
The Native M2 Pro is our premium pick. It pairs RO + UV + Copper + Alkaline + Mineraliser purification with a touch interface and an app that reports real-time TDS, which is rare in this price band. Native also publishes a service-bundled economics plan that includes filter changes, which puts it in the small group of models where long-run cost is computable.
Manufacturer specs list an 8 L storage tank and app-based TDS tracking. The Amazon listing at the time of writing shows a selling price band of ₹19,499 to ₹28,999 depending on variant and offers.
Specifications and filter data
| Purification stages | RO + UV + Copper + Alkaline + Mineraliser |
| Tank capacity | 8 L |
| Max input TDS | 300 ppm (Amazon, plausibility caveat) |
| Annual filter cost | ₹2,500/yr equivalent (₹5,000 per 2 yr) |
| App TDS tracking | Yes, real-time via app |
| Amazon rating | 4.4★ across 1,820 ratings |
| Warranty | 2 yr |
| Price band | ₹19,499 to ₹28,999 |
Why it ranks third
The M2 Pro is the strongest pick if you want connected-home features and a service plan that bundles filter changes. It ranks below the Intellon only because it does not offer an adaptive mode, and below the GLO PRO++ on raw entry price.
Who should buy it
If you live in a high-TDS borewell area, want to see TDS readings in real time, and prefer a service plan over per-cartridge billing, the M2 Pro is the most defensible pick of the three. If you do not need the app, the Intellon gives you adaptive mode for less.
Do you actually need RO?
An RO purifier alone is not always the right answer, and buying one when you do not need it costs you money and wastes water for no benefit.
RO makes sense when your input water has TDS above roughly 200 ppm, or when your supply is borewell, tanker, or brackish water. If your municipal supply is already low TDS, RO is unnecessary: it wastes water, strips minerals, and adds running cost you do not need. UV or UF purifiers handle microbiological safety without a reject stream and without membrane replacement costs.
Check your municipal water report or test your supply with a TDS meter before buying. If your TDS is well below 200 ppm on municipal piped water, these non-RO alternatives from our database do the job for less money and zero water wastage:
| Model | Type | Price band (Jul 2026) | Rating (count) | Storage | Water wasted |
|---|---|---|---|---|---|
| Faber CUV 8000 | UV + UF + Copper | ₹6,790 to ₹14,990 | 4.2★ (613) | 7 L | None (no RO reject) |
| Aquaguard Sure Mist UV+MC | UV + MC | ₹7,498 | 4.2★ (452) | No tank | None (no RO reject) |
| KENT Smart Plus UV | UV + UF + Alkaline + Copper | ₹7,999 to ₹9,999 | 4.4★ (183) | Storage-less | None (no RO reject) |
| KENT Gold Optima | Gravity UF (non-electric) | ₹2,140 to ₹3,499 | 3.6★ (15,855) | 10 L (5+5) | None (no RO reject) |
Note: the KENT Gold Optima’s Amazon TDS field claims 2,000 ppm, but UF does not reduce TDS. The manufacturer confirms it is for low-TDS tap/municipal water only, and the manufacturer’s guidance wins.

Also considered
Two RO models that did not make our three-pick shortlist but could be the right choice depending on your water and budget.
KENT Supreme Plus
The most-reviewed RO unit in our database. KENT designed it for borewell, brackish, and high-TDS water, with RO+UV+UF+Alkaline+Copper and a UV LED in the storage tank. It publishes filter intervals but no rupee filter cost, and it comes with a 3-year free extended service plan. The pick for high-TDS borewell homes that want a proven, widely-owned unit.
Check Price at Amazon ↗AO Smith Z2+ Luxe
The only unit in our shortlist that publishes a water-recovery figure: up to 30% recovery, versus the roughly 15% a typical RO manages. Its 1-year warranty covers the RO membrane and filters, which is rarer than it sounds. The pick if minimising reject water is your priority and you can accept the under-sink form factor and smaller 5 L tank.
