Best Water Purifier in India 2026: Best by Water Type & Budget

What we like
+ 3 years without service, 3-year unconditional warranty
+ Full RO with proper remineralisation
+ Best dispenser here, with power backup

What we don’t like
– It is the most expensive pick on this page

I have used the Native M3 Pro myself, and it is the purifier I rate highest on this page. A full review is coming on Geekman within a week. The idea behind it is simple: most of the pain of owning an RO is the yearly service visit and the surprise bill that comes with it. Native built the M3 Pro to remove both.

What makes it different. The filters are designed to last three years with no service, and the warranty covers filters, membranes and electrical parts whatever your water is like. That “unconditional” word matters. Many warranties quietly exclude filters or high-TDS water. This one does not.

Water quality. It runs full RO plus UV, then adds minerals back (calcium and magnesium, with copper and alkaline) so the water does not taste flat. It does not mix raw water in to hit a TDS number, which some purifiers do. If your water comes from a borewell or a tanker, that is the safer design.

Everyday use. The dispenser is the nicest here. A dot-matrix display, touch control, preset volumes for a glass, a bottle or free flow (set from the app), a guide light and a pull-out tray. The steel tank has UV inside, and the built-in power backup lets you dispense during a power cut.

App and monitoring. The Urban Company app shows water quality, filter health and usage, and warns you before something needs attention. Useful if you are away from home or want to know before the water tastes off.

Service and running cost. Urban Company says you can save over ₹26,000 across nine years compared with a normal RO that needs yearly service. That is the company’s own estimate, but the logic holds if you pay for AMC today. After three years, a filter refresh with servicing and a fresh three-year warranty is offered at a fixed price. Installation is free, though some homes need extra pressure equipment.

Urban Company Native M3 Pro vs the competition. The Native M1 is the cheaper way into the same ownership idea, with two years instead of three. The Atomberg Intellon matches the low-maintenance promise for less money but has no steel tank or touch dispenser.

What we like
+ Adaptive filtration saves minerals and filter life
+ Filters last up to two years, warranty with no AMC
+ Four modes for different water

What we don’t like
– Plastic tank, no steel option
– Atomberg is newer in water purifiers than the old names

I have used the Atomberg Intellon, and it is the most interesting purifier on this page. Atomberg is known for fans, and this is its first water purifier. Instead of running full RO all the time, it checks your water’s TDS and picks the method that fits.

How it works. The adaptive mode reads TDS. When the water is already within safe limits it uses UF and UV and skips RO, which keeps minerals in and saves the RO membrane. When TDS is high it switches to RO. You can also lock it to RO + UV, tune the taste yourself, or use Vacay mode, which flushes the filters while you are away.

Why that matters. Running RO on water that does not need it wastes water and strips minerals. If your tap water is not very hard, the Intellon is a smarter fit than a purifier that always runs full RO. If your TDS is consistently very high, lock it to RO + UV mode.

Filters and warranty. Atomberg says the filters last two years, tested up to 12,000 litres, and there is a two-year warranty with no AMC. After that you pay only for the parts that need replacing. The company puts the worst case, with every filter replaced at once, at about ₹4,000 every two years. Treat that as Atomberg’s own estimate.

Everyday use. Eight-litre tank, an app, free installation and a simple, clean look. It does not have a steel tank or a fancy touch dispenser, so the experience is practical, not premium.

Atomberg Intellon vs the competition. Against the Native M3 Pro, you lose the steel tank and the touch dispenser, but you pay far less and still get a low-maintenance promise. Against the Aquaguard Aspire Glow, you get smarter filtration but a shorter warranty.

What we like
+ 9-litre tank, the biggest here
+ TDS control and auto flush
+ Easy to find parts and technicians

What we don’t like
– Service plans are not cheap
– Plastic body and no app

I have used the KENT Grand Star, and it is a workhorse. It does not try to be clever. It gives you a big tank, a fast flow and filtration that handles the usual Indian water problems. Service costs more than I would like, but the machine is simple enough that a handy owner or any local technician can fix common faults.

Water quality. RO, UV and UF together, with a TDS control valve so you decide how much mineral content stays. Copper and alkaline stages add minerals back, and there is a UV LED in the tank to keep stored water fresh. An auto flush rinses the RO membrane to cut scaling.

Capacity and speed. The tank holds 9 litres and the purifier delivers up to 20 litres an hour. That is the biggest tank in this list, and it matters in a large family or a home with frequent guests. Even if the power is out, you have enough stored water to carry on.

Everyday use. A digital display shows purity, filter life and flow rate, and a water level indicator tells you when the tank is low. The body is food-grade ABS plastic. It looks neat, not flashy.

Service and warranty. KENT gives a one-year warranty with three years of free service. The plans are not cheap once you go beyond them. What makes up for it is that KENT parts and technicians are found nearly everywhere, and the design is simple enough to keep running without a premium plan.

KENT Grand Star vs the competition. The Native M3 Pro asks you to do nothing for three years but costs about as much. The Grand Star gives you a bigger tank and a design you can fix yourself.

What we like
+ 4-year unconditional warranty, filters and spares included
+ Very wide service network
+ Handles high-TDS water

What we don’t like
– No app or smart monitoring
– Fewer headline features than the premium picks

If your main fear is a purifier that breaks and nobody turns up, the Aspire Glow is built for you. Eureka Forbes, the company behind Aquaguard, offers a four-year unconditional warranty on this model and says filters and spares are included, with no AMC needed. That is the longest cover here.

Water quality. RO and UV with copper and alkaline stages. Eureka Forbes says it purifies municipal, borewell and tanker water up to 2000 mg/L TDS, which is a higher limit than many rivals publish. There is a fifth-generation UV LED and light cues that show status, with red for service and blue for purifying.

Warranty and service. The four-year unconditional cover is the headline. The service network is Aquaguard’s other strength, with reach across more than 19,500 pincodes. If you live outside the big metros, that coverage can matter more than any feature.

Everyday use. The status lights make it easy to see what the purifier is doing. It is a plain, reliable machine without the app and touch features of the premium models.

Aquaguard Aspire Glow vs the competition. It costs about the same as the Intellon but gives a longer warranty. The Intellon has smarter filtration, and the Aspire Glow has the wider service reach.

What we like
+ 2 years no service, filters included
+ Same service brand as the M3 Pro
+ 8-litre tank

What we don’t like
– Plastic tank
– No touch dispensing or steel tank
– Cover is shorter than the Aspire Glow

Native M1 is the entry model of Urban Company’s range. It runs the same long-life, low-service idea as the M3 Pro but with two years of cover instead of three, and without the touch dispenser and steel tank.

What you get. Ten-stage RO and UV purification with copper and alkaline and a four-in-one health booster, an 8-litre food-grade tank and a family-of-four capacity. Urban Company says the filters last two years with no service.

Service and cost. Two years of no service with filters included. After two years the filters can be refreshed at a fixed price, which includes servicing and a fresh warranty. Installation is done by Urban Company.

Where it falls short. The tank is plastic and the dispenser is a plain tap, so it feels simpler next to the M3 Pro. That is a fair trade for the price gap.

Urban Company Native M1 vs the competition. Against the M3 Pro you get one year less cover and fewer comforts. Against the Intellon, the Native M1 offers Urban Company’s service while the Intellon offers adaptive filtration.

What we like
+ 304 stainless steel tank
+ Water-saving design
+ Big service network

What we don’t like
– Only a 1-year warranty
– AMC cost after the free plan
– No smart features

This is the mid-range Aquaguard I would look at first. It gives you a surgical-grade 304 stainless steel tank, which keeps water fresher than plastic, and a design that Eureka Forbes says saves far more water than older RO models.

Water quality. RO, UV and UF with a mineral cartridge and a mega sediment filter in a nine-stage setup. The filters are rated for two years. It handles municipal, borewell and tanker water.

Water saving. RO purifiers waste water. Eureka Forbes claims up to 60 percent higher water savings than its older models. Treat that as a brand claim, but it points the right way for homes that pay for water or share a limited supply.

Service and warranty. You get free installation, a one-year warranty and a service plan with two free cleaning services. After that you will be on Aquaguard’s AMC, so plan for that cost.

Everyday use. The steel tank is the biggest comfort here. It is a conventional machine with no app, so it suits people who want something familiar.

Aquaguard Delight Aquasaver vs the competition. Compared with the Havells Aquas Pro, you get a steel tank and a bigger brand service network. The Havells offers a longer free-service window.

What we like
+ Copper, zinc and magnesium stages
+ 2 years free service, filters included
+ Free TDS meter

What we don’t like
– Plastic tank, 7 litres only
– No smart features
– Warranty terms differ between Havells models, so read the box

Havells has a reputation for tidy design and good service, and the Aquas Pro adds copper, zinc and magnesium to the water after RO and UV. It comes with two years of free service, filters included, and a TDS meter in the box.

Water quality. Seven stages: RO and UV with copper, zinc and magnesium for taste and minerals. Havells says it suits all water sources, including borewell and tanker supply.

Water saving. The company claims it saves about 40 percent of the water compared with a basic RO. As with the others, that is a brand claim.

Service and cost. Free service for two years with filters included, no AMC to sign up for in that period, and a free TDS meter so you can check your water yourself. That is a useful extra.

Everyday use. A 7-litre tank, a simple design and a familiar brand name. It is good for a small to medium family.

Havells Aquas Pro vs the competition. Against the Aquasaver, you get copper enrichment and a longer free-service window but no steel tank. Against the Native M1, it costs less but you do not get the same app-led service model.

What we like
+ Lowest cost on the list
+ Big brand with a wide service network
+ Up to 45% water saving

What we don’t like
– Only 1 year of warranty
– Plastic tank, 7 litres
– AMC cost after the first year
– No smart features

Pureit is the water brand from Hindustan Unilever, so service and parts are easy to find across India. The Wave Pro keeps things simple: RO, UV and a mineral stage, a 7-litre tank with UV in it, and a claim of up to 45 percent water savings.

Water quality. Seven stages combining RO, UV and a mineraliser. It purifies up to 20 litres an hour and has a UV LED in the tank. It is rated for borewell, tanker and municipal supply.

Water saving. Pureit claims up to 45 percent water savings with its eco-recovery design. That is the brand’s claim, but it is a useful extra at this level.

Warranty and service. You get a one-year warranty and free installation. After that you will need an AMC, so factor in the yearly cost when you compare it with the long-cover models above.

Everyday use. It is a straightforward machine with a plastic tank. It does the job and does not try to impress.

Pureit Wave Pro vs the competition. Compared with the Havells Aquas Pro, you save some money but get a shorter free-service period. Compared with the Aquasaver, you give up the steel tank.
