⚠️

Before you read the reviews: "retains essential minerals" means two opposite things

Every purifier below advertises mineral retention. Eight of the eleven achieve it the safe way — 100% of the water passes the RO membrane, then a cartridge doses calcium and magnesium back in. Two (both KENT models here) use a TDS controller, an adjustable valve that routes part of your untreated feed water around the membrane and blends it into the glass. The eleventh, the Atomberg Intellon, is a third case: it never blends, but its Adaptive Flow mode skips the RO membrane altogether when the input TDS reading is low.

A bypass is not selective. Whatever fraction skips the membrane carries everything dissolved in it, so there is no setting that admits calcium and stops fluoride, nitrate or arsenic. The blend ratio is also a knob a technician turns at installation to reach a pleasant TDS reading — it is tuned for taste, not for your contaminant profile.

That is why Mineral handling is the first row of every spec table on this page, and why it carries the heaviest weight in our scoring. A TDS controller is defensible when your water's only problem is taste and salts. If you bought RO because of a specific chemical contaminant, it partially undoes what you paid for. Our water purifier buying guide walks through sizing, feed-water testing and filter costs before you shortlist a model.

Water purifier reviews: recovery, TDS and running cost

Specs, the honest pros and cons, and who each one is for.

Pureit

Pureit Eco Elite 2X RO+UV+MF+Alkaline Water Purifier

The right RO architecture, the best numbers on paper, and not enough buyers yet to be sure.

Mineral handling: 100% RO + post-membrane alkaline mineraliser (no bypass) - listing states 'bypass-free technology'
Purification Method: Reverse Osmosis, Ultraviolet, Microfiltration
Stages: 8
Maximum Flow Rate: 24 Litres Per Hour
Supported Water TDS Level Maximum (PPM): 2000
Water Saving Percentage: 50.0
Filter Life Cycle: 2 Years
Capacity: 10 litres
Item Weight: 9.6 Kilograms
Material Type: Plastic (100% food-safe tank)
Model Number: PIRO10081OECA6B
Country Of Origin: India

Scores highest because it does the engineering correctly - full RO then remineralise, with no blending valve - while publishing a real 50% recovery figure and pairing the joint-largest tank here with 24 L/h. The catch is evidence: 91 India reviews is thin, so treat it as the informed bet rather than the safe one.

PROS

＋ Bypass-free by design — 100% of the water passes the RO membrane before minerals are dosed back
＋ The 50% water recovery is published as an actual spec rather than a marketing claim (it beats the 40% IS 16240 minimum)
＋ Joint-largest tank here at 10 L and 24 L/h — the best size-and-speed pairing in this list
＋ 2-year warranty covers every filter so there is no AMC decision until year three
＋ Free external sediment filter included — the part other brands bill ₹1,200-1,275 for at installation
＋ 8-stage RO+UV+MF handles borewell / tanker / municipal feed up to 2000 ppm

CONS

－ Only 162 ratings and 91 unique India reviews — the least-proven product in this list
－ One detailed verified buyer reports the alkaline mineraliser not restoring minerals as advertised
－ Several reports of leaks within a day or two of installation — and of Pureit installation support being hard to reach
－ Running cost after the 2-year warranty is entirely unproven — no buyer has reached year three yet
－ The 'alkaline' framing is a taste feature that carries no health benefit and should not drive the purchase

Who should buy it

For buyers who want the architecture right and the numbers published. 100% of the water passes the RO membrane and an alkaline mineraliser doses calcium and magnesium back afterwards — there is no blending valve to undo the filtration you paid for. It also carries 50% recovery as a real specification, the joint-largest tank here at 10 L with a brisk 24 L/h, a 2-year warranty covering every filter, and the external sediment filter rivals bill ₹1,200–1,275 for at installation. The trade is evidence: 162 ratings and 91 unique India reviews make this the least-proven unit in the list, so treat it as the informed bet rather than the safe one.

Aquaguard

Aquaguard Enrich Ritz Pro RO+UV+Copper+Alkaline Water Purifier

Buy it for the four-year zero-cost warranty, not for the smart features.

Mineral handling: 100% RO + post-membrane copper/alkaline dosing 'as per BIS norms' (no bypass)
Purification Method: Reverse Osmosis, Ultraviolet
Stages: 12
Maximum Flow Rate: 24 Litres Per Hour
Operating Pressure Range: upto 3 kg/sq.cm
Supported Water TDS Level Maximum (PPM): 2000
Water Saving Percentage: 40.0
Filter Life Cycle: 4 Years
Capacity: 5 litres
Material Type: ABS body with SS 304 tank
Model Number: GWPDERRCS0002X
Installation Type: Countertop

The best ownership economics in this list by a wide margin - four years with no filter, spare or service bill removes the single biggest hidden cost in the category. The purification and disclosure are genuinely good too. What lets it down is the smart layer, which frequently does not work, and a 5 L tank that is small for the money.

PROS

＋ Four-year unconditional warranty — zero filter / spare / service cost and no AMC to negotiate
＋ Copper and alkaline dosed after the membrane and referenced to BIS norms rather than sold as a health cure
＋ Surgical-grade SS 304 storage tank with a lifetime warranty against corrosion
＋ 12-stage Nanopore filtration rated for lead / mercury / arsenic / cadmium / microplastics / pesticides
＋ 24 L/h production rate with real-time TDS-in and TDS-out shown on the unit
＋ Publishes recovery / flow rate / max operating TDS / filter life — unusually complete disclosure

CONS

－ Only a 5 L tank at ₹21,999 — thin for a family of four and limiting during power cuts
－ The advertised Wi-Fi app and 21-point health check repeatedly fail to work; several buyers call this out as misleading
－ Loud operating noise and error codes are a recurring complaint
－ 40% recovery is only the legal minimum rather than a leadership figure at this price
－ Review-authenticity flags: the listing carries verified reviews dated as far back as 2015 so the 7,602-rating headline is inherited from older Aquaguard Enrich models
－ Eureka Forbes AMC practices draw persistent complaints once the warranty window ends

Who should buy it

Buy this one for the ownership maths, not the smart features. Four years with zero filter, spare and service cost and no AMC removes the single biggest hidden expense in this category, and against a category norm of ₹6,000–8,500 a year that is a large, verifiable saving. Copper and alkaline are dosed after the membrane and referenced to BIS norms rather than sold as a health cure, and the 12-stage Nanopore stack is rated for lead, mercury, arsenic, cadmium, microplastics and pesticides. Accept two things before you pay ₹21,999: the advertised Wi-Fi app and 21-point health check frequently do not work, and 5 L is a thin tank for a family of four.

₹21,999 ₹37,000 SAVE 41%

Native by Urban Company

Native M1 Water Purifier by Urban Company (10-Stage RO+UV+Copper+Alkaline+Mineraliser)

The purifier that refuses to blend - and says so on the box.

Mineral handling: 100% RO + post-membrane mineraliser (no bypass) - listing states 'No MTDS mixing, no RO bypassing either'
Purification Method: 10-Stage RO+UV boosted with Copper, Minerals & Alkaline
Supported Water TDS Level Maximum (PPM): 2000
Filter Life Cycle: 2 Years
Capacity: 8 litres
Item Weight: 8.6 Kilograms
Material Type: Polypropylene (food-grade tank)
Model Name: Native M1
Manufacture Year: 2025
Country Of Origin: India
Whats in the box?: Water Purifier, Pre-filter, power adapter, installation kit & TDS meter

The most straightforwardly correct architecture in this list at a sensible price: full RO every time, minerals added back afterwards, and no blending valve to undo the filtration you paid for. Running cost is excellent and the evidence base is large. The weak spot is what happens when you need help - Urban Company's support is the most-complained-about part of owning it.

PROS

＋ States the anti-bypass position outright — 100% RO then remineralise with no MTDS mixing and no membrane bypass
＋ Two years with no service visits / no AMC / no filter cost — then a fixed ₹5,000 all-in refresh
＋ 2-year unconditional warranty covering filters / membranes / electricals regardless of input water quality
＋ 8 L tank suits a family of four and holds a useful buffer through a power cut
＋ Ships the handheld TDS meter IS 16240 requires when there is no built-in display
＋ Large and genuinely Indian evidence base — 418 unique verified India reviews read for this report

CONS

－ No rated recovery efficiency published anywhere — a real disclosure gap for a brand positioned on engineering honesty
－ Several verified buyers report output TDS well outside the useful band (27 ppm in one case and 350 ppm in another)
－ Urban Company support is widely reported as unreachable once the 2-year window ends — the flip side of a no-service model
－ Damaged or already-used units on delivery come up repeatedly
－ Installation may need extra pressure equipment at ₹250-950 billed on top

Who should buy it

The pick if your supply is borewell, tanker or high-TDS and you want a purifier that never blends. Native states the anti-bypass position outright — full RO every time, minerals restored afterwards, no MTDS mixing — which is the correct answer when the problem is a chemical contaminant rather than taste. Running cost is excellent: two years with no service visits, then a fixed, published ₹5,000 refresh for two more, and it ships the handheld TDS meter IS 16240 requires. The weak spot is help: Urban Company support is the most-complained-about part of owning it, and the no-service model means there is no technician relationship to fall back on.

₹14,499 ₹20,999 SAVE 31%

AO Smith

AO Smith Z9 Pro Black RO Water Purifier (Ambient & Instant Hot, Copper + Alkaline)

The best filtration engineering here, wrapped in the weakest warranty.

Mineral handling: 100% RO via patented Side Stream membrane + post-membrane copper/alkaline mineraliser (no bypass)
Purification Method: Reverse Osmosis (patented Side Stream membrane)
Stages: 8
Supported Water TDS Level Maximum (PPM): 1999
Capacity: 10 litres
Installation Type: Under Sink
Material Type: Plastic body, stainless steel hot tank
Model Number: IGR010082OZBHC5
Manufacture Year: 2024

If purification architecture alone decided this list, the Z9 Pro would win: a patented side-stream membrane, no bypass anywhere, silver-charged protection for stored water and the best water recovery on offer. Hot water is a genuine convenience. What holds it back is ownership - one year of cover at Rs.21,999, and an AMC sales push that starts before that year is even up.

PROS

＋ Patented Side Stream RO membrane — 100% of the water is filtered with no blending valve anywhere
＋ Best claimed water economy in this list at up to 55% recovery
＋ Instant hot and ambient dispensing from a stainless steel hot tank
＋ Silver Charged Membrane Technology targets secondary microbial growth in stored water
＋ 10 L storage — joint-largest in this list
＋ 1-year comprehensive warranty does include the RO membrane and filters — which many rivals exclude

CONS

－ Only one year of warranty at ₹21,999 — the weakest coverage-to-price ratio in this list
－ Multiple buyers report being pushed to buy an AMC while the unit was still in warranty
－ Units failing at around two months and around one year appear repeatedly in recent reviews
－ Installation delays and technicians not showing up are a recurring complaint
－ The copper and alkaline cartridges are taste consumables rather than health features — dosed correctly after the membrane but still a recurring bill that falls to you from year two
－ The water testing kit that should ship with it has been reported missing
－ Only 518 ratings — a moderate evidence base rather than a deep one

Who should buy it

For buyers who care about the membrane above everything else and want instant hot water on tap. The patented side-stream membrane means 100% of the feed is filtered with no blending anywhere, Silver Charged Membrane Technology targets regrowth in the stored water, and the claimed 55% recovery is the best water economy here — roughly 18 litres of feed for 10 litres of drinking water, against 25 at the legal minimum. Only take it if you are comfortable with one year of cover at ₹21,999, the weakest coverage-to-price ratio in this list, and with an AMC sales push that several buyers report starting inside the warranty.

₹21,999 ₹33,000 SAVE 33%

Native by Urban Company

Native M2 Pro Water Purifier by Urban Company (Touch Dispensing + Battery Backup)

The M1's engineering with a touchscreen - and a battery claim buyers dispute.

Mineral handling: 100% RO + post-membrane mineraliser (no bypass) - listing states 'No MTDS mixing, no RO bypassing either'
Purification Method: 10-Stage RO+UV boosted with Copper, Minerals & Alkaline
Supported Water TDS Level Maximum (PPM): 300 (Amazon field; brand states 2000 for the line)
Filter Life Cycle: 2 Years
Capacity: 8 litres
Item Weight: 8.5 Kilograms
Material Type: Polypropylene (food-grade tank)
Model Name: M2 Pro
Manufacture Year: 2025
Installation Type: Freestanding

Filtration-wise this is the M1, which is a good thing: full RO every time, minerals added back afterwards, no blending. The Rs.3,500 premium buys a touchscreen, preset dispensing and app diagnostics. Whether it buys a battery is genuinely unclear - several buyers say the advertised power backup was not in the unit they received, and that is a listing-accuracy problem worth resolving before you pay for it.

PROS

＋ Same no-bypass always-full-RO architecture as the M1 and stated explicitly on the listing
＋ Touch-screen dispensing with preset glass / bottle / free-flow volumes
＋ Real-time TDS-in and TDS-out plus a 12-parameter filter health check through the Urban Company app
＋ Two years zero-cost then a fixed and published ₹5,000 all-in refresh for two more
＋ 2-year unconditional warranty regardless of input water quality or consumption
＋ 8 L food-grade tank suitable for a family of four

CONS

－ Multiple verified buyers report the advertised in-built power backup is simply absent from the unit received
－ No rated recovery efficiency published — and the Amazon spec table's 300 ppm max TDS contradicts the brand's own 2000 ppm figure
－ Urban Company service is the most-complained-about aspect (as across the Native range)
－ Leaks immediately after installation and a persistent plastic smell come up repeatedly
－ ₹3,500 more than the M1 for features that are mostly interface rather than filtration

Who should buy it

The M1's filtration — same no-bypass, always-full-RO architecture — with a touchscreen, preset glass and bottle pours, and real-time TDS-in / TDS-out through the app. Worth ₹3,500 more than the M1 only if you value the interface, because the purification is identical. Two cautions: several verified buyers report the advertised in-built power backup was simply absent from the unit they received, so confirm it before you pay for it; and the Amazon spec table's 300 ppm maximum operating TDS contradicts the brand's own 2,000 ppm figure for the line.

Aquaguard

Aquaguard Delight Aquasaver RO+UV+UF+MC Water Purifier

The country's best-selling purifier, and the biggest gap here between what is promised and what is serviced.

Mineral handling: 100% RO + post-membrane Mineral Charge cartridge (no bypass) - Aquaguard uses a zero-pressure pump to prevent channelling
Purification Method: Reverse Osmosis, Ultraviolet, Ultrafiltration, Mineral Charge
Stages: 9
Maximum Flow Rate: 20 Litres Per Hour
Operating Pressure Range: Upto 3 bar
Supported Water TDS Level Maximum (PPM): 2000
Water Saving Percentage: 40.0
Filter Life Cycle: 2 Years
Capacity: 6.2 litres
Material Type: Acrylonitrile Butadiene Styrene
Model Number: GWPDDLTSR13B00
Manufacture Year: 2025

The engineering is sound and the disclosure is above average - Mineral Charge genuinely doses after the membrane, and Aquaguard publishes the numbers IS 16240 asks for. It is also the cheapest 9-stage RO+UV+UF here. Buy it for that. Do not buy it for the 2-year filter claim, which buyers say lasts about five months, and go in expecting Eureka Forbes service to be the hard part.

PROS

＋ India's best-selling water purifier on Amazon and the #1 in its category — a very large and current evidence base
＋ Mineral Charge doses minerals after the membrane rather than blending raw water back in
＋ 9-stage RO+UV+UF with NanoPore filters targeting pesticides / microplastics / lead / mercury
＋ Publishes recovery / flow rate / max operating TDS / filter life — better disclosure than most
＋ Additional mega sediment filter protects the internal filters and extends their life
＋ Widest service network in India at 19,000+ pin codes and the cheapest 9-stage RO+UV+UF here

CONS

－ The marketed 2-year filter life is directly contradicted by verified buyers reporting roughly five months
－ Eureka Forbes after-sales service is the single most-complained-about thing about this product
－ Around 100 one-star verified India reviews landed in roughly seven weeks — a heavy negative flow beneath a healthy-looking headline
－ AMC pressure at the one-year mark to replace filters sold as two-year
－ 6.2 L tank is small for the volume of households buying it
－ Recent review dates cluster heavily on single days so the top-of-page star mix flatters the product

Who should buy it

The cheapest route to a genuine 9-stage RO+UV+UF with post-membrane Mineral Charge, from the widest service network in India at 19,000+ pin codes. Buy it for the stack, the price and the disclosure — Aquaguard publishes recovery, flow, maximum TDS and filter life, which most rivals do not. Do not buy it for the 2-year filter claim, which verified buyers put closer to five months, and go in expecting Eureka Forbes after-sales to be the hard part: roughly 100 one-star India reviews landed in about seven weeks, almost all of them about service rather than the machine.

Atomberg

Atomberg Intellon Adaptive Water Purifier (RO+UF+UV+Alkaliser, 4 Modes, IoT)

The cleverest purifier here, applying its cleverness to the wrong variable.

Mineral handling: Mode-switching: 100% RO in RO+UV mode, but Adaptive Flow SKIPS the RO membrane entirely below a TDS threshold. TasteTune adjusts output TDS by post-stage mineral dosing, not by blending.
Purification Method: RO + UF + UV with Alkaliser / Intelligent Filtration System
Stages: Dynamic 7-stage
Maximum Flow Rate: 25 Litres Per Hour
Operating Pressure Range: 10-30 PSI
Supported Water TDS Level Maximum (PPM): 1500
Water Saving Percentage: 50
Filter Life Cycle: 2 Years
Capacity: 8 litres
Material Type: Acrylonitrile Butadiene Styrene
Model Name: Atomberg Intellon
Manufacture Year: 2025

Everything around the membrane is excellent - 50% recovery, 25 L/h, no AMC ever, and app-based filter health that ends the technician's-word-against-yours problem. The trouble is the headline idea. Deciding whether to use the RO membrane based on TDS assumes TDS tells you whether water is safe, and it does not. If your water is municipal and the issue is taste, this is a smart buy. If you are in a fluoride, arsenic or nitrate belt, buy something that always filters.

PROS

＋ 50% water recovery and 25 L/h — the fastest purification in this list
＋ No AMC ever: two years fully covered then a published per-component rate card with app alerts
＋ Genuinely transparent about test conditions — 12,000 L filter life stated at 1500 ppm / 200 ppm hardness / 5 NTU
＋ App shows real-time filter health so replacement is evidence-based rather than technician-declared
＋ TasteTune sets output TDS by dosing minerals at the final stage rather than by blending raw water
＋ Four selectable modes including a Vacay mode that auto-cleanses while you are away

CONS

－ Adaptive Flow skips the RO membrane entirely when input TDS reads low — unsafe logic if your water carries fluoride / arsenic / nitrate (none of which a TDS sensor can detect)
－ Worst reliability profile in this list: 19% of all lifetime ratings are 1-star
－ The spotless recent star mix is misleading — all 20 most recent reviews fall in a three-day window while a steady 1-star stream continues underneath
－ Lowest maximum operating TDS ceiling here at 1500 ppm
－ Defective-on-arrival units and month-after-month recurring faults are a recurring theme
－ Its own listing repeats an untraceable WHO claim about TDS below 300 ppm being a safety threshold

Who should buy it

Right for municipal supply where the problem is taste and hardness: 25 L/h is the fastest flow in this list and 50% recovery matches the best published figure here, there is no AMC ever (two years covered, then a published per-component rate card), and app-based filter health ends the technician's-word-against-yours problem. Wrong if you are in a fluoride, arsenic or nitrate belt — Adaptive Flow decides whether to use the RO membrane from a TDS reading, and TDS cannot see any of those contaminants. Its reliability record is also the weakest here, with 19% of lifetime ratings at one star.

₹16,999 ₹25,999 SAVE 35%

Pureit

Pureit Wave Plus RO + Mineral + UV Water Purifier

Good filtration for under Rs.8,000, undone by what the filters cost afterwards.

Mineral handling: 100% RO + post-membrane mineral enhancer cartridge (no bypass) - Pureit states no bypass across this line
Purification Method: Reverse Osmosis, Ultraviolet
Stages: 6
Maximum Flow Rate: 20 Litres Per Hour
Supported Water TDS Level Maximum (PPM): 2000
Capacity: 7 litres
Item Weight: 5.59 Kilograms
Material Type: Plastic (100% food-grade tank)
Model Number: WPWB500
Installation Type: Wall Mount
Whats in the box?: Water purifier, Installation kit, Handheld TDS Meter, Warranty card

For the money this does the important thing correctly - full RO, then minerals dosed back, no blending - and buyers confirm real TDS reduction. It also ships the TDS meter the standard requires and refuses to dispense on an expired filter. The problem arrives at month eight, when a filter change can cost close to half what you paid for the machine. Buy it knowing the consumables, not just the sticker.

PROS

＋ Cheapest RO+UV here with a genuine post-membrane mineral cartridge and no blending valve
＋ Verified buyers confirm real reduction — 670 ppm down to 55 and 350 ppm down to 35
＋ Smartsense stops dispensing if the filter is overdue rather than quietly serving unpurified water
＋ Handheld TDS meter included as IS 16240 requires when there is no built-in display
＋ WQA-tested with 20 L/h flow and a genuine 2000 ppm ceiling
＋ 4.4 stars with a 77% five-star share — the best-rated budget unit here

CONS

－ Filter replacement reported at ₹3,250 at eight months — on a unit that buyer picked up at a ₹5,500 sale price and still close to half today's ₹7,799 sticker
－ Complaints skew to product failures rather than service — motherboard failure within a month and leakage at four months
－ Some buyers report output TDS stuck at 10-15 ppm even after replacing the mineral cartridge
－ No rated recovery efficiency published — the 45% figure is marketing
－ Only a 1-year warranty and ₹1,500 quoted for in-warranty leakage repair
－ 804 ratings is a moderate base for a product selling 800+ a month

Who should buy it

The cheapest unit here that still does the important thing correctly: full RO, then minerals dosed back, no blending valve, with UV over the stored water and a real 2,000 ppm ceiling. Verified buyers confirm it works, reporting 670 ppm down to 55 and 350 down to 35, and Smartsense stops dispensing on an overdue filter rather than quietly serving unpurified water. Go in with eyes open on consumables — one verified buyer paid ₹3,250 for filters at eight months on a machine they had bought at a ₹5,500 sale price. Even against today's ₹7,799 sticker that is close to half the machine's price back within a year, which on a budget purifier is the whole argument.

Aquaguard

Aquaguard Sure Delight RO+MC 1X Water Purifier

The cheapest way in, provided your water is genuinely just salty.

Mineral handling: 100% RO + post-membrane Mineral Charge cartridge (no bypass)
Purification Method: Reverse Osmosis, Mineral Charge
Stages: RO + Mineral Charge (no UV, no UF)
Operating Pressure Range: Upto 3 kg/sq.cm
Supported Water TDS Level Maximum (PPM): 100 (Amazon field - contradicts the listing's >200 ppm requirement)
Filter Life Cycle: 1 Year / 6,000 L
Capacity: 6.2 litres
Item Weight: 6.2 Kilograms
Material Type: Acrylonitrile Butadiene Styrene
Model Number: GWPDDLTRM00B00
Installation Type: Countertop
Manufacture Year: 2024

A deliberately simple machine that does the mineral question correctly and, perhaps because there is less to go wrong, posts the lowest recent 1-2 star share in this list without a review burst propping it up. But it has no UV and no UF, so there is nothing disinfecting the water sitting in its tank, and it only works above 200 ppm. Right for hard municipal water where the problem is salts. Wrong if bacteria or a low-TDS contaminant is your concern.

PROS

＋ Cheapest purifier in this list at ₹6,999 and from India's widest service network
＋ Lowest recent 1-2 star share here at 10% — and unlike the other unit on 10% it is not inflated by a same-day review burst
＋ Mineral Charge doses minerals after the membrane rather than blending raw water back
＋ Free service plan worth ₹2,000 covering installation / a maintenance visit / unlimited repairs in year one
＋ Simple stack with fewer components to fail and cartridge life rated at 1 year or 6,000 L
＋ NABL and WQIA certification stated on the listing

CONS

－ No UV and no UF — the least-equipped purifier here with no disinfection over stored water
－ Only works on feed water above 200 ppm TDS which rules out many municipal supplies
－ The listing's own spec table states a 100 ppm maximum operating TDS contradicting its 200 ppm minimum — unreliable published data
－ No recovery efficiency or production rate published at all
－ Buyers report filters worn out and water taste degrading at around the one-year mark
－ 6.2 L tank and countertop-only installation

Who should buy it

For hard municipal or borewell water above 200 ppm where salts and taste are the entire problem. It is the cheapest purifier here, the simplest stack, and — perhaps because there is less to go wrong — its 10% recent 1–2 star share is the lowest in this list, and unlike the Delight Aquasaver's matching 10% it is not propped up by a burst of same-day reviews. Mineral Charge doses after the membrane, and the first year includes installation, a maintenance visit and unlimited repairs. Not the one to buy if bacteria are a concern: there is no UV and no UF, so nothing disinfects the water sitting in the tank, and it will not work on feed below 200 ppm.

KENT

KENT Grand RO Water Purifier (RO+UF+TDS Control + UV LED Tank)

Well-built, widely serviced, and fitted with the one feature this guide would ask you to turn off.

Mineral handling: TDS CONTROLLER (bypass blending) - an adjustable valve routes part of the feed around the RO membrane. Marketed as 'retaining essential natural minerals'.
Purification Method: Reverse Osmosis, Ultrafiltration, UV LED in tank, TDS Control
Maximum Flow Rate: 20 Litres Per Hour
Supported Water TDS Level Maximum (PPM): 2000
Capacity: 8 litres
Item Weight: 7 Kilograms
Material Type: Plastic
Model Name: Grand RO
Manufacture Year: 2024
Installation Type: Wall Mount / Freestanding

As hardware this is a competent purifier with a genuinely useful UF stage, in-tank UV and the best service reach in India. The reservation is the TDS controller: it works by letting raw water bypass the membrane, and the unit is sold for borewell and tanker supply, where that is exactly the wrong trade. If you buy it, ask the installer to set the blend to minimum and ask Kent whether the model has been tested for Cryptosporidium and Giardia - IS 16240 clause 6.3.3.2.1 makes those tests mandatory for bypass-blending systems.

PROS

＋ RO+UF with a UV LED inside the storage tank which protects water while it sits
＋ India's largest service network at 19,000+ pin codes — reachable by app / WhatsApp / phone / email
＋ Membrane fused into its housing to prevent tampering and push-fit connections to reduce leaks
＋ 8 L tank and 20 L/h flow are both solid for a family of four
＋ ISI mark stated with max operating TDS 2000 published
＋ Long-established product with a large and current Indian review base

CONS

－ Has a TDS controller which blends unfiltered feed water back into your drinking water — on a purifier sold for borewell and tanker supply that partially undoes the RO you paid for
－ If your reason for buying RO is fluoride / nitrate / arsenic then the bypass is working against you — and no bypass setting can be selective
－ Buyers report roughly ₹6,000 in repairs after the first year and high recurring filter costs
－ An external pre-filter is commonly billed at ₹1,275 at installation and is not in the box price
－ Membrane failures at around ten months with ₹3,000+ demanded to replace it
－ The handheld TDS meter and other listed accessories have been reported missing from the box

Who should buy it

Competent hardware — a genuinely useful UF stage, a UV LED inside the storage tank that protects water while it sits, push-fit connections and the best service reach in India. The reservation is the TDS controller, which works by letting raw feed bypass the membrane, on a purifier sold for borewell and tanker supply. If you buy it, have the installer set the blend to minimum, and ask Kent whether this model has been tested for Cryptosporidium and Giardia — IS 16240:2023 clause 6.3.3.2.1 makes those tests mandatory for bypass-blending systems. Budget for the running cost too: buyers report about ₹6,000 in repairs after year one.

KENT

KENT Supreme Plus Alkaline+Copper RO Water Purifier

The longest feature list in this list, and the highest bill to keep it running.

Mineral handling: TDS CONTROLLER (bypass blending) plus post-membrane copper and alkaline cartridges. The bypass is the problem; the copper/alkaline cartridges are taste features and recurring consumables.
Purification Method: RO+UV+UF + Alkaline + Copper + TDS Control + UV LED in tank
Maximum Flow Rate: 100 Litres Per Day (20 L/h)
Supported Water TDS Level Maximum (PPM): 90 (Amazon field - not credible for a borewell-marketed purifier; KENT rates this line at 2,000 ppm)
Capacity: 8 litres
Item Weight: 8 Kilograms
Material Type: Plastic
Model Name: KENT Supreme Alkaline Black
Warranty Description: 3 Years Extended Free Service after 1 Year Warranty
Manufacture Year: 2024

On paper this has everything: RO, UV, UF, auto-flush, in-tank UV LED, and a copper and alkaline cartridge on top. In practice two of those are taste features you are also paying to replace, one of them blends unfiltered water back into your glass, and buyers consistently report Rs.6,000-8,500 a year to keep it going. The RO itself works well on hard water. Everything around it is expensive.

PROS

＋ The most complete stage list here — RO+UV+UF with auto-flush and a UV LED inside the tank
＋ Auto-flush rinses the membrane to reduce scaling and extend its life — a genuine engineering feature
＋ Verified performance on very hard water — a buyer on 2,300 ppm feed reports 240 ppm output
＋ Largest India review base in this list at 15,356 ratings
＋ 1-year warranty plus a stated three years of extended free service
＋ India's largest service network at 19,000+ pin codes

CONS

－ Worst running cost here — buyers report ₹8,500 a year in maintenance and ₹6,000-8,000 annually is the common expectation after warranty
－ Has a TDS controller that blends unfiltered feed water back in — on a purifier sold for borewell and tanker supply
－ The copper and alkaline cartridges are extra recurring consumables rather than a benefit — copper is a capped parameter so more is not better
－ This listing carries the strongest unsupported health claims in the category — on copper and on alkaline water
－ Buyers report it wastes a significant amount of water and no recovery figure is published to check against
－ Individual reliability reports are harsh — one unit failing five times in six months and another serviced every fifteen days

Who should buy it

The longest feature list here and the highest bill to keep it running — buyers report ₹6,000–8,500 a year. The RO itself performs on very hard water: one buyer on 2,300 ppm feed reports 240 ppm output, and auto-flush plus an in-tank UV LED are real engineering. But the copper and alkaline cartridges are taste consumables you pay to replace, not health features, and the TDS controller blends unfiltered feed back into the glass on a purifier marketed for borewell supply. Only worth it if you want every stage on the box and are budgeting for the AMC.

How each purifier handles the mineral question

Full RO, then remineralise (no blending valve)

Pureit Eco Elite 2X

100% RO + alkaline mineraliser — listing states "bypass-free technology"

Aquaguard Enrich Ritz Pro

100% RO + copper/alkaline dosed post-membrane, "as per BIS norms"

Native M1 / M2 Pro

100% RO + mineraliser — "No MTDS mixing, no RO bypassing either"

AO Smith Z9 Pro

Patented Side Stream membrane, then copper + alkaline strictly after

Aquaguard Delight / Sure Delight

100% RO + Mineral Charge cartridge downstream

Pureit Wave Plus

100% RO + mineral enhancer cartridge, no bypass

Mode-switching (skips the membrane on a TDS reading)

Atomberg Intellon

Full RO in RO+UV mode, but Adaptive Flow bypasses the membrane entirely below a TDS threshold

Why it matters

TDS is a palatability proxy — it cannot see fluoride, arsenic, nitrate, pesticides or bacteria

When it is fine

Municipal supply where the issue is taste and hardness; it genuinely extends membrane life

TDS controller (blends raw feed back in)

KENT Grand

Adjustable brass-screw valve; marketed as "retaining essential natural minerals"

KENT Supreme Plus

Same bypass, plus copper and alkaline cartridges as separate consumables

Ask before buying

IS 16240 cl. 6.3.3.2.1 mandates Cryptosporidium and Giardia testing for bypass-blending systems — ask if this model has it

Which water purifier to buy

One question separates these eleven purifiers: does every drop pass the RO membrane, or does a valve blend part of your feed water back in? Our picks all answer that the right way — the rest is tank size, running cost and who turns up when it breaks.

Best Overall

Pureit Eco Elite 2X · ₹13,699

Buy this if you want the architecture right and the numbers on the label — no blending valve, 50% published recovery, 10 L tank and every filter covered for two years.

Best Value

Aquaguard Delight Aquasaver · ₹10,999

Buy this if you want a full 9-stage RO+UV+UF for the least money and the widest service network in India — but budget for filters sooner than the 2-year claim suggests.

Best for Borewell & High-TDS

Native M1 by Urban Company · ₹14,499

Buy this if your water is borewell, tanker or high-TDS and you want a purifier that never blends, with two years of zero service cost and a fixed ₹5,000 refresh after.

Best Under ₹10,000

Pureit Wave Plus · ₹7,799

Buy this if the budget is tight but you still want full RO plus a real mineral cartridge and UV over the stored water — just price the consumables before you commit.
