Did you know? Urban family with an average spending consumable over ₹5,000 for the purpose of water purifier servicing and electrical bills. Shocking, isn’t it? Still, it is necessary to note that access to clean drinking water is a privilege for many people. The prices vary from ₹7,000 to ₹50,000, so, determining the efficient and cost-effective water purifier is important. But worry not! In this guide I will unveils the best water purifier that combines uncompromising purification with surprisingly low maintenance cost
List of the Top Water Purifiers with Low Maintenance Costs in India
Atomberg Intellon – Intelligent filtration system, well optimized water recovery and 2 year zero cost maintenance and app based filter monitoring.
Aquaguard Ritz Pro – this is where things start to get a bit fancy – its all stainless steel and has titanium filters to boot – so you know its got some serious filtration power. And the best part? The filters will last you two years if your water’s TDS rating is under 1,000 ppm.
Urban Company Native M2 – great for those wanting zero hassle and full-service convenience – just set it and forget it, basically. I reckon its best suited for families looking for a low-maintenance way to keep their water clean and clear for two full years, no questions asked.
Aquaguard Sure Delight Aquasaver – Most water efficient purifier on this list and most praised for low maintenance. 60% water recovery, double life filters and annual cost under ₹6,000.
Aquaguard Blaze Insta – its got shorter filter life than some of the others on this list but its makes up for it with instant hot water – perfect for modern kitchens that want to do both hot water and purification – so a pretty handy all-in-one option.
Aquaguard Enrich Marvel 2X – Best water purifier for high TDS areas. Best option for tough water conditions and can handle input up to 2,000 ppm. Double life filters lasting 2 years.
Aquaguard Aura 2X – Although slightly premium priced than others on this list, I think this is the best option for zero maintenance seekers as it has no service for 2 years and comprehensive warranty.

- RO Filter life up to 12000L
- Adjustable TDS levels
- Pay only for filter/part replacement
- IoT-enabled app
- Real-time TDS display
- AutoCleanse technology
- 2-year comprehensive warranty

Trust me, the Atomberg Intellon Water Purifier delivers on every front.
The machine can automatically analyse source water TDS and switch between full RO+UF+UV mode for high TDS water and mineral preserving UF+UV mode when TDS is within safe limits. Using the Atomberg Intellon is super easy – the LED ring interface provides animated feedback and the digital display shows real time TDS levels, it let me know what’s happening with water at any given time.
The 7 stage dynamic purification system delivers exceptional water quality consistently. The Atomberg Intellon processes water through pre filtration, inline sediment removal, pre carbon treatment, membrane protection, UF and RO membranes and finally UV sterilization with alkaliser treatment. TasteTune Mode allows me to adjust filtered water TDS between three ranges (50-100 ppm, 75-125 ppm or 100-150 ppm), the optimal 75-125 ppm range provides perfectly balanced mineralization.
I used the Intellon with moderately hard water (450 ppm TDS) and I consistently got the promised recovery rates while maintaining output TDS at 85 ppm. The 25 liters per hour capacity is more than enough for a family, it fills the 8 liter food grade ABS tank in about 20 minutes.
AutoCleanse Technology does frequent automatic cleaning of filters and membranes, which extends the life of the components. The Atomberg Intellon’s RO membrane has scaling prevention technology which worked even with high mineral content water. Filter life is up to 12,000 liters or 2 years whichever comes first and the system provides accurate replacement timing through smart monitoring. Post warranty maintenance is very affordable with individual filter replacement costing between ₹200-₹1,100 per component, total ₹2,960 for complete overhaul.
The purifier struggled slightly with very low water pressure below 10 PSI, requires a booster pump installation which Atomberg provides at no extra cost. I tested the system with tough contaminants like chlorine treated municipal water and iron rich borewell supply – both were handled well, though the pre-carbon filter required more frequent cleaning with heavily chlorinated water.
Performance analysis across different modes showed consistent output, RO+UV mode gave 65-85 ppm TDS from 600+ ppm input, UF+UV mode gave 180-220 ppm from 250 ppm source water.
Specifications:
- Water Purification Technology- RO+UF+UV+Alkaliser
- Water storage tank -8 Litres
- Water Purification stage – 7
- Wattage – 50 Watts
- NO AMC for 2 Years
What I Liked
- 9-stage purification
- RO+UV+UF combo
- 2 Years Filters life if TDS under 1000 PPM
- RO filter lasts up to 12000 Ltrs
- Enhances water taste
- Adds essential minerals
- Up to 60% recovery
- Free first-year service
What I Disliked
- Small 6.2L tank
- Pre-filter not included
- Pressure valve extra
- Only 1-year warranty
- Filter life TDS-dependent
Among water purifiers, Aquaguard Sure Delight RO+UV+UF 2X is tied with Kent Grand Plus and Livpure Glo for the most comprehensive filtration system. Unlike Havells Max which is bulky and utilitarian, Aquaguard Delight NXT is compact and modern, feels premium. Smart LED indication system is also intuitive and looks much better than most.
There is some assembly required with this purifier, but minimal. I just had to mount the wall bracket and secure the unit using the provided screws which needs to be tightened properly. Took me under 30 minutes, although at 6.2 kg in weight you do need someone to help you hold it during installation.
Smart LED indicators which operate service alerts and filter warnings are clear and very easy to use. But 9 stage purification process is much more complex. Filter system has multiple cartridges, each representing a different purification stage. I have to monitor the filter life indicator which requires me to understand when each component needs to be replaced.
During testing I found Aquaguard Delight NXT delivered extremely pure water with impressive TDS reduction (220 PPM to 47 PPM). Sitting next to it in our kitchen I could feel the difference in taste within minutes, and in less than an hour our client entire family felt the difference in water quality.
That’s not surprising given it’s one of the most energy efficient in our round-up using just 40 watts on its highest purification setting. At current average electricity rates of ₹5.74 per unit, that means on its highest setting this model costs roughly ₹0.24 per hour to run.
Good design, generally easy to use, lowest AMC and excellent purification performance and filter life 10,000 litre that runs 2 years, if source water TDS is under 1000 ppm, makes me rate Aquaguard Delight NXT the best water purifier for medium to large families.
Specifications:
- Water Purification Technology- RO+UV+UF
- Water storage tank – 6 Litre
- Water Purification stage – 7
- AMC – No service required for 2 years
What I Liked
- Long filter life last upto 24 months

- Night glow
What I Disliked
- Service is only available in big cities.
The Urban Company M1 water purifier comes with an exciting new 2 year filter life that can save consumers up to ₹18,000 on total ownership and service costs. This innovative technology requires service only once every 2 years thanks to filters that last for up to 24 months. With its 9-stage water purification process including UV, UF, and TDS Control, the M1 purifier ensures delivery of pure and safe drinking water. It also offers a 2 year unconditional warranty that covers all filter replacements, membranes and electrical parts at zero added service cost. In the 3rd year, AMC is only ₹5,000 and the tank itself lasts upto 2 years, so in the 4th year AMC cost is zero.
The sleek and minimalist panel has a handy digital display and a single dispensing tap below. Its contemporary aesthetic is likely to seamlessly blend with most modern kitchen designs. Made using durable and easy-to-maintain high-quality plastic, the tap is a convenient lever-type placed on the front for easy access to softer and less chlorinated purified water whenever you need it. I love the smart and efficient design.
With its In-tank UV feature that enhances water safety via continuous UV light inside the storage tank, and a useful guide light that glows while dispensing to help you fill water even in the dark, the M1 purifier delivers on functionality too. This wall-mounted unit also comes with a retractable tray for hands-free bottle filling that can be tucked away when not in use. It is ideal for all water sources including tanker, borewell, municipal and tap water supply. The 8 liter food grade tank keeps water mineral-enriched and free of harmful chemicals.
Tested the TDS and was impressed to find it reduces hardness and chlorine levels, delivering a noticeably softer and fresher tasting drinking water. With such transparent AMC pricing and a purifier filter that lasts up to 2 years, this model is perfect for modern urban homes looking for low maintenance costs. I think Urban Company has more than delivered on their promise of smart app connectivity and an efficiently designed water filter with ultra low maintenance requirements.

What sets the Aquaguard Aura 2X Life Purifier apart is its affordable AMC, priced near ₹2250. This new-age purifier comes with advanced filters that last for 2 years, eliminating the need for service during that time. It utilizes Dual Layer Filter Technology (DLFT) which increases the RO membrane’s surface area, improving water recovery. You can see this is the same technology used in the Urban Company Native M1 Purifier. The Aura 2X Life includes free installation, an external pre-filter inside the box, and a 2-year warranty.
Suitable for water with 0 to 2000 mg/L TDS, testing showed it reduced input water at 1230 mg/L TDS to 107 mg/L after purification. In contrast, the Urban Company model handles only up to 1500 mg/L TDS, a 500 mg/L difference. You will find advanced water-saving technology helps save 50% water, rejecting just 500 mL per liter purified. Infusing the right copper level from the first drop, it meets BIS norms.
With a 7-liter tank holding about 35 glasses of 200 mL each, the food-grade ABS ensures bacteria, virus and chemical free purified water. The external tank level is visible. Specs are similar to the Urban Company M2 but it costs around ₹3000 less.
I have found the large capacity perfect for a family of four. You can see the affordable AMC and advanced dual layer filtration technology make the Aura 2X Life a great value. As you will find, it effectively reduces TDS while saving water, with a 7-liter tank and 2-year warranty.
Specifications:
- Water Purification Technology- RO+UV+Active Copper+Taste Adjuster

- 2 Year Filter Life
- 10,000 Litre RO filter life
- High TDS capacity
- Compatible all sources
- Mega sediment filter
- Low power consumption
- Smart LED indicators

Compact and efficient design, the Aquaguard Enrich Marvel RO+UV+UF 2X has 10 stage purification with RO Max 2X technology and UV e-boiling equivalent to 20+ minutes of traditional boiling. This is a great addition to most homes but it’s in the higher price range.
Controlling the Aquaguard Enrich Marvel is done through the LED indication system which gives clear visual feedback for all operations. The interface shows service reminders, tank full indicators and filter life warnings through separate electronic alerts. It also has customizable auto shut off and filter replacement scheduling.
By default Aquaguard will turn on its MTDS (Mineral Total Dissolved Solids) optimization technology which will automatically adjust mineral levels based on source water. After 10 purification cycles this intelligent system will learn your water source and optimize the 3-in-1 Active Copper Technology for consistent mineral enhancement.
Otherwise the 6.2 litre capacity is good for 4-6 members of the family, can easily accommodate daily drinking water needs with 20 litres per hour flow rate. It can handle large cooking vessels up to 3 litre capacity directly from the dispenser. And has a compact 32L x 27.8W x 48H cm footprint which is always a nice touch.
Across my tests I found the Aquaguard Enrich Marvel performed well and efficiently with low running cost. In my municipal water test cycle the running cost was ₹9 for 10 litres compared to Kent Grand Plus ₹10.5 for similar output, achieved “excellent clarity with complete removal of chlorine taste and odour”.
In our test, the Enrich Marvel delivered great specifications. At 20 liters per hour it maintains quality and gives over 40% water recovery.
The 3-in-1 Active Copper Technology infuses minerals as per BIS norms throughout the filter life.
Not only is the Enrich Marvel good for homes that need long term performance but also effective against many contaminants. If you need 2 year filter protection at reasonable price, this model is a great value.
I then tested its borewell water purification cycle which cost around ₹5.8 10 litres compared to Pureit Ultima ₹10 for similar high TDS water treatment. While it handled water up to 2000 PPM TDS, it required additional pre-filtration for very turbid sources.
For best mineral retention and taste enhancement I would recommend activating the Active Copper Booster mode which costs 16p per 10 litre cycle. This premium mode gives you remarkably enriched water with optimal copper, calcium and magnesium levels as per BIS standards.
Overall the Enrich Marvel is a balanced water purifier with proven NanoPore technology and one of the most comprehensive purification process. With 10 stage process and genuine 2 year filter guarantee the Enrich Marvel not only removes contaminants but also maintains performance.

What I Like
- Insta hot water at 80°C with dual stainless steel tanks lifetime warranty.
- Up to 360 liters daily output with 15 liters per hour TDS up to 2,000 ppm.
- TDS reduction from 540 to 85 ppm (90% reduction) in testing.
- Child lock and auto shut off.
What I Dislike
- Tank Size is small – only 5.5 L.
The Aquaguard Blaze Insta is a game changer with water purification and instant hot water. Perfect for modern kitchens that need both.
But I would recommend it more for those who need hot water instantly as the filter life (6,000-12,000 liters depending on variant) is shorter than others on this list.
With surgical-grade 304 stainless steel dual tanks, this water purifier is durable. The 0.5-liter hot water tank gives 80°C water in 10 seconds to 2 minutes. And it has 2 year filter life guarantee that lasts up to 10,000 liters.
But the filter life depends on your water TDS being below 200 ppm. Just like we saw in Kent Grand Plus and HUL Pureit Copper, in this Aquaguard you can see multi stage purification technology. Similarly in this purifier you can get RO+UV protection against contaminants. It also has NanoPore filters, Active Copper Technology, 9 stage purification process – all of this you can activate with simple touch controls.
And in this you’ll find surgical grade stainless steel tanks with separate compartments. Its advantage is that you get corrosion resistance and water stays fresh for longer periods. And another very good thing is that you’ll find child lock feature for hot water safety.
If you want to make instant tea or coffee – if you’ve set a goal to reduce your gas usage then you can dispense hot water directly in this and you can see instant 80°C water flow.
And when we tested its TDS reduction capability our input water TDS was 220 and it brought it down to. So I found that it achieves 84.7% TDS reduction efficiency.
But its maintenance cost is ₹7,499 for 2 years. This seems very expensive to me. The Aquaguard weighs slightly more at around 8kg compared to other RO purifiers we tested but the surgical-grade stainless steel tanks and child-lock safety feature for hot water dispensing gives peace of mind for families with young children. The Blaze Insta has 40% water recovery so it’s eco-friendly despite its 800W heating element power consumption.
Specifications:
| Dimensions (cm) | 35.5L x 35.5W x 52H cm |
| Weight | 13.2 Kg |
| Purification Rate | 15 liters per hour |

What I Like
- 15 liters per hour capacity and 5-liter steel tank storage for daily purification needs
- 9 stage purification technology with special emphasis on Titanium Duo filters that lasts 2 years for TDS below 1,000 ppm
- Bacterial reduction (99.9999%) and virus elimination (99.99%) with over 40% water recovery
- 5th Gen UV LED technology with 10 year lifespan and zero mercury and instant purification
What I Disliked
- Low Water Storage Capacity
This is the only water purifier in this list that comes with stainless steel tank, and there’s another reason to include it in this list because this water purifier comes with a two-year comprehensive warranty.
And it provides a guaranty for 12,000 liters. But there’s one condition that your input water’s TDS should be below 1000 PPM. Just like we saw with the Atomberg Intellon and Native M2 water purifiers, in this water purifier you can see the TDS in real-time. Similarly, in this water purifier too, you can check the real-time TDS. It also comes with WiFi, and device health, water quality TDS – all of this you can monitor in your mobile app.
And in this, you’ll find fifth generation UV LED. Its advantage is that you get almost zero waiting time and its life is up to 10 years. And another very good thing is that you’ll find zero harmful mercury in it.
If you want to track daily how many liters of water you drink – if you’ve set a goal that you need to drink 3 to 4 liters daily, then you can set goals in this and you can see how many liters of water you’ve drawn from this water purifier.
You can track this daily, weekly, and monthly. And when we tested its TDS, our input water TDS was 480 and it brought it down to 60 TDS.
So I found that it achieves a full 90% TDS reduction. But its water storage capacity is 6.2 liters. This seems very low in my opinion.
If you have four-five family members, you’ll need to frequently refill and purify water. If the storage was above 8 liters, it would have been better, but its filtration is very fast. You’ll see the full tank within 20 minutes.

Breaking Down My Research Procedure
For all the water purifiers we have listed in this list, to test them, we first checked the lifespan of their RO filter as claimed by the company. After that, we also checked their TDS reduction capacity. And we also checked at what TDS level they can purify to get least 12,000 liters and ensure the water purification runs for at least 2 years. After that, we analysed all the parameters including the complete evaluation of TDS reduction and purification speed.
Here we have covered TDS Controller Vs Mineralizer in Water Purifier
Below is a chart featuring the genuine 2-year filter life purifiers we’ve analyzed.

*For TDS below 1,000 ppm
For this article and to find the best water purifiers with extended filter life I also looked at the warranty terms—what does “unconditional” really mean? For this analysis I looked at official warranty documents and user reviews.
This was a great opportunity to see real cost savings, get maintenance insights, compare technologies and ultimately find which water purifiers offer long term value.
I should also mention that in addition to researching specs, user reviews show that models with 2 year warranty consistently outperform regular purifiers in total cost of ownership.
Here we have compared RO that guarantees a 2-year filter life for Input water TDS 1500 PPM.

Frequently Asked Questions
How much does it cost to maintain a normal RO water purifier?
Popular brands like KENT, Aquaguard, AO Smith, Pureit use different types of filters used in a typical 8 or 9 stage RO system, each with their own optimal replacement timeline:
- Pre-Carbon Filters: These granular activated carbon filters are the first line of defence against contaminants. They remove sediment and chlorine to extend the life of downstream filters. Carbon filters should be replaced every 6-12 months or when they have processed 3000 litres, brands like Aquagurd Aura, and KENT grand RO show the life span of an RO.
- Sediment Filters: Sediment filters come next and remove fine particulate matter that can damage the RO membrane. They usually last about 6-12 months or 3000 liters before needing replacement, life is same as I shown you above.
- RO Membrane: This gradually wear out over time. On average, models like Aquaguard Aura, KENT Grand RO replacing the membrane every 10 to 12 months or around 6000 liters to maintain good performance. Replacement cost is around
- Post-Carbon Filter: A final carbon filter polishes water before it reaches the tap. These should be replaced on the same schedule as the pre-filter, every 6-12 months.
| Filter | Frequency | Life | Average Cost (₹) |
| Pre-Carbon | 6 months | 3000 Litre | ₹350 |
| Sediment | 6 months | 3000 Litre | ₹350 |
| RO Membrane | 10–12 months | 6000 Litre | ₹1500 |
| UV Lamp | 24 Months | 12000 Litre | ₹500 |
| Post Sediment | 6-12 Months | 6000 Litre | ₹350 |
What are the Maintenance costs of UV water purifiers?
Kent, a leading brand, charges ₹1500-₹3000 per year which covers the sediment, activated carbon filters that need replacing every 6-8 months.
