Amazon RO Water Purifier Prices August 2026: Rs. 3,999 to Rs. 19,499

Read the specification and this looks like a bargain: reverse osmosis, ultraviolet, ultrafiltration, seven stages, TDS control, eight litres of storage - a longer feature list than the Rs. 19,499 machine at the end of this read. Read the listing again for what is not there. No service plan, no filter-life term, no installation claim, no named service network. On a water purifier those omissions are the entire purchase, because an RO membrane needs replacing roughly annually and a machine whose filters you cannot buy is a plastic box on a wall. Amazon shows 4.1 from 169 ratings, a small base. Seventy-one per cent off Rs. 14,000 from a seller with no retail presence is a list price nobody has been charged. Buy it only if you already know where you will get filters.

A stage in this vocabulary is any element water passes through - a sediment pre-filter, a carbon block, the RO membrane, a UV chamber, a mineral cartridge - so ten stages is a longer list than most branded machines here quote, and it costs less than a third of what they do. The number is not meaningless, but it is not comparable across brands either, because nobody defines it the same way. Copper and zinc cartridges add trace minerals back after RO strips them, which is a genuine function and also the most heavily marketed one in this category. What this listing does not state, like every machine in this first chapter, is what a filter change costs or who performs it. Amazon shows 3.8 from 287 ratings - the lowest average in the read.

Thirteen thousand and ninety-one ratings at 4.1 is a serious body of feedback - the second-largest in this entire read - and it is the strongest argument any machine in this chapter has. Whatever the brand's retail standing, a lot of people have bought this and most of them have not come back angry. Against that: 79 per cent off a stated Rs. 24,999 is the deepest badge in the read, and Rs. 24,999 would place this above every Aquaguard, Havells and KENT machine seated here at list price, which is not a claim anybody can defend. AQUA D PURE returned two near-identical listings in our pull nine rupees apart, with 13,091 and 1,912 ratings respectively - so even within one seller, the count belongs to a listing rather than to a product. No service or filter term is stated.

• Buying logic: The best-evidenced cheap machine, with the biggest fiction attached

This is the card where the shelf changes character. Aquaguard is Eureka Forbes's brand and operates one of the largest direct service networks for water purifiers in India - technicians who come to the house, on a schedule, with the right cartridge. The listing puts a number on it: a free service plan stated as worth Rs. 2,000. Against a Rs. 3,999 machine that says nothing at all about service, that Rs. 2,000 claim closes most of the price gap on its own, before you consider whether the cheaper machine's filters are obtainable at all. The technology is thinner here - RO plus a mineral cartridge, not the ten-stage lists below - and that is the trade this chapter makes: fewer acronyms, a named service contract. Amazon shows 4.2 from 1,840 ratings.

• Price: Rs. 7,999 (stated MRP Rs. 13,000)
• After the sale: free service plan stated as worth Rs. 2,000

Pureit is Hindustan Unilever's water business, which matters here for the same reason Aquaguard's ownership matters: filters are sold through a national distribution chain and will still be available in year four. Four-point-four from 821 ratings is the joint-highest average in the first half of this read on a base large enough to be meaningful. The listing claims up to 45 per cent recovery - a water-saving figure describing how much of the input becomes drinking water rather than reject - which is a genuinely useful specification in a category that wastes a great deal of water and which almost nothing else in this read quotes. RO plus mineral plus UV is the mainstream stack. At Rs. 8,199 this is the most sensible purchase under Rs. 10,000 on the page.

• Price: Rs. 8,199 (stated MRP Rs. 13,499)

Borewell and tanker suitability is a real and underrated specification. Municipal supply, borewell water and tanker deliveries have very different dissolved-solids loads, and a purifier tuned for one can struggle with another - if your building runs on tankers in summer, this line matters more than any number of stages. Livpure is an established Indian purifier brand with its own service network. The problem is the evidence: 3.3 from 29 ratings is the lowest average in this read and the thinnest branded base, so no rating pill appears on this card. Seven litres of storage is modest but adequate for a couple. At Rs. 8,889 you are paying Rs. 690 more than the Pureit above it for a source claim and considerably less reassurance.

Water-purifier installation in an Indian metro runs Rs. 500 to Rs. 1,500 depending on the tap tee-off, the drain run and whether a wall needs drilling, and it is normally charged separately. This listing states it is included, which is worth as much as several of the mineral claims above it. Eight stages with a copper cartridge is a mainstream stack, and Livpure's 4,642 ratings at 3.9 give a substantial base to judge it on - the average is middling rather than good, which is worth weighing against the same brand's GLO PRO++ on the next card, rated 4.1 across nearly fifteen thousand ratings. At Rs. 9,499 this sits at the point on the shelf where branded machines with service terms become genuinely affordable.

• Price: Rs. 9,499 (stated MRP Rs. 17,490)
• After the sale: free standard installation stated

Fourteen thousand eight hundred and ninety-eight ratings at 4.1 is the biggest body of published feedback anywhere on this shelf, and unlike the Aquaguard Delight family later in this read, this count is not repeated on another Livpure listing in our pull - the Glo Star shows 4,642 and the Allura pair shows 1,880. So it is the machine's own. The claim to read carefully is 'No Filter Cost for 2 years', which carries an asterisk on the listing and therefore has conditions we cannot see from the search page. Taken at face value it is the most valuable single line under Rs. 10,000 here, because filters are the recurring cost of owning a purifier. RO plus UV plus UF is the full stack. This is the best-evidenced machine on the page.

• Price: Rs. 9,999 (stated MRP Rs. 15,500)
• After the sale: no filter cost for 2 years, asterisked

Eight thousand nine hundred and nineteen ratings at 4.2 looks like decisive evidence until you find the same 8,919 on the Delight Aquasaver at Rs. 12,499 and again on the Delight Aquasaver stainless-steel version at Rs. 15,999, both seated later in this read. One pool of feedback, three machines, a Rs. 5,500 price spread. Amazon links variants of a product line under one review pool and geyser brands do exactly the same thing, so this is a category-wide problem rather than an Aquaguard one. The machine itself is sound: six stages, RO plus UV plus UF, and the stated Rs. 2,000 service plan that is Aquaguard's real advantage. Judge it on the service network and the specification, not the number.

• Price: Rs. 10,499 (stated MRP Rs. 18,000)
• After the sale: free service plan stated as worth Rs. 2,000

This is a UV purifier with heavy-metal removal and no RO membrane, and it is on this page deliberately, because RO is not automatically the right answer. Reverse osmosis exists to strip dissolved solids from hard or brackish water; if your supply is soft municipal water with a low TDS reading, an RO machine will strip minerals you wanted, waste two or three litres for every litre it delivers, and cost more to run. UV kills biological contamination without any of that. The correct test is a TDS meter, which costs a few hundred rupees and is the single best purchase anyone reading this page can make before buying a purifier at all. Amazon shows 4.2 from only 19 ratings, so no pill appears here. Two-year filter life is stated.

• Price: Rs. 11,500 (stated MRP Rs. 15,500)
• After the sale: 2-year filter life stated
• Key detail: Rs. 11,500, Aquaguard ENRICH Neo UV+HMR water purifier, heavy metal removal, 2-year filter life stated - 26% off a stated Rs. 15,500

Havells is an Indian electricals manufacturer with a wide dealer and service footprint, and its purifier listings are the most consistent in this read about after-sales terms - both Aquas Pro machines state a free-service period, and the 3X model later states three years. Two years of free service is a larger commitment than a free filter, because it covers the visit and the labour as well. The mineral stack here is the longest of any branded machine on the page: copper, zinc and magnesium together. Whether three additives do more for you than one is not a question this listing answers. Amazon shows 3.9 from 3,856 ratings, and note that the same 3,856 appears on the Aquas Pro 3X at Rs. 17,890 - another shared pool.

• Price: Rs. 11,890 (stated MRP Rs. 20,000)
• After the sale: 2 years free service stated
• Key detail: Rs. 11,890, Havells Aquas Pro 7L water purifier, RO+UV+copper+zinc+magnesium, 2 years free service stated - 41% off a stated Rs. 20,000

• Rating: 3.9 from 3,856 Amazon ratings
• Buying logic: Buy the two-year service, not the three minerals

A conventional domestic RO unit discards two to three litres of reject water for every litre it purifies, which in a city on tanker supply or a house with a borewell is a real and recurring cost that no purifier listing likes to discuss. Pureit has named a product line after fixing it, and that alone puts this listing ahead of most of the shelf on honesty. RO plus UV plus MF - microfiltration rather than the ultrafiltration most machines here quote - is a full stack. Hindustan Unilever's distribution means cartridges will be available. Amazon shows 4.1 from 2,878 ratings, its own rather than pooled. At Rs. 12,099 this is the machine to look at first if your water is metered, tankered or scarce.

• Price: Rs. 12,099 (stated MRP Rs. 24,850)
• After the sale: filter-life claim stated

This is the second of the three Aquaguard Delight listings sharing one pool of 8,919 ratings, and the comparison with the Rs. 10,499 machine nine cards up is worth making carefully because the two are easy to confuse. This one adds MC Tech and a mega sediment pre-filter - a coarse first-stage cartridge that catches grit before it reaches the finer filters, which extends the life of everything downstream and genuinely matters on borewell or tanker supply. It also states a two-year filter life rather than a Rs. 2,000 service plan. On a clean municipal line the cheaper Delight is the better buy; on gritty water this one is, and the sediment filter is the reason, not the price.

• Price: Rs. 12,499 (stated MRP Rs. 26,500)
• After the sale: 2-year filter life stated
• Key detail: Rs. 12,499, Aquaguard Delight Aquasaver RO+UV+UF+MC Tech, mega sediment filter, 2-year filter life - 53% off a stated Rs. 26,500

Twenty-five per cent off Rs. 16,999 is the joint-mildest discount claim on this page, and a brand that discounts lightly is usually quoting a list price it means. V-Guard is a Kerala-headquartered electricals manufacturer with dense southern-Indian service coverage - if you are in Kerala, Tamil Nadu or coastal Karnataka, its technician network is among the fastest of any brand here. A zero-service-cost claim is the strongest after-sales language in this read, stronger than a filter warranty, because it covers the visit. What is missing is evidence: 31 ratings at 4.2, so no pill on this card. Note also RO plus UF without UV, which is a shorter stack than most machines at this price.

• Price: Rs. 12,699 (stated MRP Rs. 16,999)
• After the sale: zero service cost stated
• Key detail: Rs. 12,699, V-Guard Aurina 2X RO+UF water purifier, DuoGuard filter technology, zero service cost stated - 25% off a stated Rs. 16,999

KENT is the brand that made RO a household word in India, and the Grand is its best-known model - the transparent-topped wall unit that appears in a decade of television advertising. The numbers support the reputation: 4.4 from 7,947 ratings is the joint-highest average in this read on the second-largest base, and that count is its own rather than pooled across capacities. The specification is deliberately plain - RO plus UF plus TDS control, no copper, no zinc, no alkaline, no mineral marketing - which after twelve cards of acronym stacking reads as confidence rather than omission. What the listing does not state is a service or filter term, which for a brand with this distribution is a smaller gap than it would be lower down the page.

• Price: Rs. 12,899 (stated MRP Rs. 19,500)
• After the sale: none stated beyond RO and TDS control
• Key detail: Rs. 12,899, KENT Grand RO water purifier, RO+UF+TDS control - 34% off a stated Rs. 19,500

Thirty thousand rupees is the second-largest stated MRP in this seated set and it sits on a machine selling at Rs. 12,999 - a 57 per cent claim, the deepest of any branded listing here and deeper than three of the four unbranded machines in chapter one. Read the selling price. What is genuinely good is the after-sales language: a two-year filter life with a comprehensive plan is the most complete term Aquaguard states anywhere in this read, better than the Rs. 2,000 service plans on its cheaper Delight models. Active copper is the mineral claim. Amazon shows 4.0 from 3,075 ratings, its own. At Rs. 12,999 with two years of filters and service covered, this is the strongest Aquaguard on the page.

• Price: Rs. 12,999 (stated MRP Rs. 30,000)
• After the sale: 2-year filter life with a comprehensive plan stated

Native is Urban Company's own appliance brand, and the argument for it is structural rather than technical: the company's entire operation is dispatching trained technicians to Indian homes, which is precisely the capability a water purifier needs and the thing every other brand on this page has to bolt on. A no-service-charge claim from a services company means something different from the same claim on a listing by a manufacturer. Eight stages with RO, UV and a mineraliser is a mainstream stack, and 29 per cent off Rs. 18,999 is a restrained claim. Amazon shows 4.3 from 685 ratings, a modest but real base. If you have had bad experiences getting a purifier serviced, this is the listing that addresses it directly.

• Price: Rs. 13,499 (stated MRP Rs. 18,999)
• After the sale: no service for 2 years stated

Unlimited free service visits is a stronger commitment than anything else stated on this page - stronger than two years of filters, stronger than a plan valued at Rs. 2,000 - because it removes the per-visit charge that is the usual friction in owning a purifier. The listing does not state how long 'unlimited' runs for, which is the question to ask before buying, but even a bounded version of that promise is valuable. Alkaline filtration raises the pH of the output after RO strips it, a claim with more marketing behind it than evidence. Havells has real national service reach. Amazon shows 3.8 from 183 ratings, which is a middling average on a small base, and the weakest part of this listing.

• Price: Rs. 13,970 (stated MRP Rs. 25,000)
• After the sale: free unlimited service visits stated

Almost every purifier on this shelf stores its purified water in a food-grade plastic tank. A stainless steel tank resists biofilm - the slime that forms on wet plastic surfaces over years and is the reason purifier tanks need periodic sanitisation - and it does not impart taste. Three machines in this read state one, and this is the cheapest. Six and a half litres is on the small side, which is the trade for steel at this price. pH balance is the alkaline claim under another name. Amazon shows 3.7 from 561 ratings, the second-lowest average in the read, which is a genuine caution and the reason this is not our pick at this price band despite the tank.

• Price: Rs. 13,990 (stated MRP Rs. 27,000)

RO plus UV plus UF plus copper plus alkaline is the longest branded stack on this page, and it is paired with the claim that matters most on a purifier: no filter cost for two years. That combination - complete filtration and a covered recurring cost - is what the Rs. 3,999 machine in chapter one cannot offer at any price, and it is the clearest illustration on this shelf of what the extra ten thousand rupees actually buys. Amazon shows 4.0 from 1,880 ratings, and the same 1,880 appears on the Allura X at Rs. 18,490 later in this read, so treat it as a line-level signal rather than this model's own. At Rs. 13,999 this is the most complete machine under Rs. 14,000.

Indian kitchens are small and the wall space beside a sink is usually the most contested surface in the house. A purifier designed to sit in a corner rather than flat against one wall is a genuinely useful piece of engineering, and Havells states the design is patented. If your kitchen has an awkward corner and no clean run of wall, this listing solves a problem that no amount of filtration technology addresses. Copper, zinc and alkaline is the mineral stack. The stated Rs. 32,295 is the largest MRP in this seated read and should be ignored entirely - it is Rs. 12,000 above the same brand's Aquas Pro 3X. Amazon shows 4.1 from 3,558 ratings, its own count.

Four-point-four from 183 ratings is the joint-highest average on this page, though the base is small enough that it should be read as encouraging rather than settled. What is solid is the platform: the Eco line is Pureit's water-saving RO family, so this inherits the recovery-rate advantage of the Eco Water Saver earlier in this read while adding alkaline filtration and a stated two-year filter warranty. A filter warranty is not the same as free filters - it covers failure rather than replacement - and that distinction is worth confirming before you buy. Hindustan Unilever's distribution means cartridges will be stocked for years. At Rs. 14,699 this is the best-specified Pureit on the shelf.

Compare this with the Rs. 12,499 Delight Aquasaver nine cards up: same RO plus UV plus UF plus MC Tech, same mega sediment filter, same two-year filter life, same 8,919 shared ratings. The stated difference is the stainless steel tank, and it costs Rs. 3,500. That is a lot for a tank, and Havells sells a steel-tank machine at Rs. 13,990 - though with weaker ratings and a smaller 6.5-litre capacity. Whether steel is worth it depends on how long you keep appliances: over a decade, a tank that does not develop biofilm is worth real money in sanitisation visits and taste. Over three years it is not. This is the third and last of the Delight family in this read, and the most expensive.

Three years is the longest stated service period on this page, a year longer than anything else here, and on a machine that needs an annual visit it is worth roughly three call-outs plus the cartridges. Set against the Aquas Pro 7L at Rs. 11,890 with two years of free service, the 3X asks Rs. 6,000 more for one extra year and whatever the '3X' designates - the listing does not spell it out beyond the same RO, UV, copper and zinc stack, which is the frustrating part. Amazon shows 3.9 from 3,856 ratings, and that is the same 3,856 the cheaper Aquas Pro carries, so the feedback does not separate the two models either. On stated value, the Rs. 11,890 version is the better buy.

This is the top of Aquaguard's range in our pull once the paise-artefact listings are removed, and it puts together the three things worth paying for on this shelf: a stainless steel tank, a two-year filter life, and Eureka Forbes's direct service network, which remains the largest dedicated water-purifier service operation in India. Copper is the mineral claim. Amazon shows 4.0 from 3,077 ratings, its own count rather than the Delight family's pooled 8,919, which makes it more useful than the numbers on Aquaguard's cheaper machines. At Rs. 17,999 you are paying Rs. 5,000 over the Nexen for the tank and the finish; the Nexen's comprehensive plan is the better value, and this is the better object.

Preset touch dispensing means you press once for a glass or a bottle and the machine delivers that measured volume and stops, which sounds trivial until you have overfilled a bottle at a tap for the tenth time that week. The battery backup matters more in practical terms: an Indian kitchen with an unreliable supply gets water from this machine during a power cut, which nothing else on this page offers. Twenty-five per cent off Rs. 26,000 is the joint-mildest badge in the read. Amazon shows 4.4 from 2,497 ratings - the joint-highest average on the largest base of any machine above Rs. 15,000, which is the strongest combination on the page. It is also five times the price of the machine on card one, with a shorter list of purification stages.
