Livpure GLO PRO++Check price ↗Best Premium
Native M2 ProCheck price ↗If you just want the shortcut: Atomberg Intellon is the best overall pick for most Indian homes, Livpure GLO PRO++ is the value pick 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 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 homes.
11 RO Water Purifiers Compared: Price, Yearly Filter Cost and Water Savings
Every RO purifier has two running costs: the yearly filter bill and the water it sends down the drain as reject. Prices are Amazon selling prices on 30 October 2026, rounded to the nearest ₹100; ratings and review counts are from the Amazon listings on the same date. Variant ceilings, maker prices and MRPs were not refreshed and keep their July 2026 date. “Not published” means the figure was not on the maker page or Amazon listing we read in July 2026.

| KENT Grand | ₹11,900 on 30 Oct 2026 for the KENT New Grand, which the Amazon link now opens (KENT Grand ₹12,899 in Jul 2026) | 4.4★ (8,506), for that listing | 8 L | 2,000 ppm | Not published | Not published (intervals only) | Partial | 1 yr + free service |

Running-cost disclosure tally (as read in July 2026): 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 list a recovery percentage or savings claim, and 1 (Atomberg) uses an adaptive design that avoids reject water when TDS is safe.
Atomberg Intellon
The Atomberg Intellon is our best overall pick because it publishes an annual filter cost and is the only model in this comparison with 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 saves water and minerals.
Manufacturer specs list an 8 L storage tank, RO + UF + UV purification, and an adaptive mode that responds to input TDS. The Amazon listing on 30 October 2026 shows a 4.2-star rating across 2,237 ratings and a selling price from ₹17,500. In July 2026 the listing showed variants up 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 | 4.2★ across 2,237 ratings |
| Warranty | 2 yr all-inclusive (covers consumables) |
| Amazon price | From ₹17,500 on 30 Oct 2026 (variants to ₹25,999 in Jul 2026) |
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 less than half the price (about ₹7,500 against ₹17,500 on 30 October 2026).
Livpure GLO PRO++
The Livpure GLO PRO++ is our best value pick. It is the second-lowest Amazon price of the 11 RO models on 30 October 2026 and still includes a complete RO + UV + UF chain. Manufacturer specs list RO + UV + UF purification and a 7 L storage tank.
The Amazon listing on 30 October 2026 shows a selling price from ₹7,500 and a 4.1-star rating across 15,194 ratings. In July 2026 it showed ₹8,929 against an MRP of ₹15,500; the MRP has not been refreshed.
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 15,194 ratings |
| Warranty | 1 yr |
| Amazon price | From ₹7,500 on 30 Oct 2026 (MRP ₹15,500 in Jul 2026) |
Why it ranks second
For buyers on a strict budget whose supply is mostly municipal, the GLO PRO++ covers the essentials at less than half the Amazon price of the Intellon (about ₹7,500 against ₹17,500). A complete RO + UV + UF chain at this price is a real plus.
The main drawback: no published filter cost
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. Native also publishes a service-bundled economics plan that includes filter changes, which makes it one of the 3 models in this comparison where long-run cost is computable.
The Amazon listing gives an 8 L storage tank and app-based TDS tracking; Native’s specs here come from the Amazon listing only, because we could not read a maker page for it. On 30 October 2026 the listing shows a selling price from ₹17,500, a 4.4-star rating and 3,694 ratings. In July 2026 the listing showed variants up to ₹28,999.
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 3,694 ratings |
| Warranty | 2 yr |
| Amazon price | From ₹17,500 on 30 Oct 2026 (variants to ₹28,999 in Jul 2026) |
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 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. Its Amazon listing gives a maximum input TDS of 300 ppm, which we could not confirm with the maker, so check that against your water before choosing it for borewell supply. If you do not need the app, the Intellon gives you adaptive mode at the same Amazon price (about ₹17,500 on 30 October 2026).
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 what a UV or UF purifier is rated for (the Faber CUV 8000 and Aquaguard Sure Mist below both list an input TDS limit of 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 and adds running cost you do not need. UV or UF purifiers have no RO reject stream.
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, the non-RO alternatives listed below waste no water, because they have no RO reject stream:
| Model | Type | Amazon price (30 Oct 2026) | Rating (count) | Storage | Water wasted |
|---|---|---|---|---|---|
| Faber CUV 8000 | UV + UF + Copper | ₹6,000 (variants to ₹14,990 in Jul 2026) | 3.5★ (73) | 7 L | None (no RO reject) |
| Aquaguard Sure Mist UV+MC | UV + MC | ₹7,500 | 4.2★ (451) | No tank | None (no RO reject) |
| KENT Smart Plus UV | UV + UF + Alkaline + Copper | No Amazon price shown on 30 October 2026 (₹7,999 to ₹9,999 in Jul 2026) | 4.4★ (11) | Storage-less | None (no RO reject) |
| KENT Gold Optima | Gravity UF (non-electric) | ₹1,900 (variants to ₹3,499 in Jul 2026) | 3.6★ (15,946) | 10 L (5+5) | None (no RO reject) |
Note: the KENT Gold Optima’s Amazon listing claims 2,000 ppm for TDS, but UF does not reduce TDS. The manufacturer confirms it is for low-TDS tap/municipal water only, and the manufacturer’s guidance wins.

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 use 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 compared 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: taken from the Amazon listing on 30 October 2026.
- Price: the Amazon selling price on 30 October 2026, rounded to the nearest ₹100. Maker prices and MRPs are from July 2026.
Why filter cost matters more than sticker price
An RO purifier’s true cost is the sticker price plus filter replacements over the years you own it. A unit that is 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.
