We do the comparisons for you, and we research the company, its reputation, customer service, and overall product quality. See? Easy!

Why Should You Trust Us?

We have reviewed over 150 purifiers from 20 different brands.

Unlike other review sites, we use a standardized rating system to give every water purifier an unbiased rating.

This score is calculated using our in-depth product review, brand reputation, and their customer service.

We have been testing water purifiers since 2017. In our reporting, we’ve studied at length to understand what makes one water purifier better than others.

We’ve also spoken with representatives of multiple water-purifier brands to verify their claims. We’ve gone hands-on with some of our picks because overall dependability, durability, and user-friendliness are essential in an appliance that’s crucial for your health.

Who This is For?

This guide is for people who want a new RO water purifier.

You can easily buy an RO water purifier online or from your nearest kitchen appliances store. But buying the right one is often not that easy.

Hundreds of models from several brands with different purification technologies make finding the perfect water purifier for your home quite challenging.

Buying a new water purifier has to be a well-thought-out decision as your family’s health depends on it.

Why RO Purifiers?

RO water purifiers are an excellent choice for most Indian houses. RO (Reverse Osmosis) purifiers are so popular in India that the term ‘RO’ has become synonymous with ‘water purifiers.’

Combined with UV, UF, and MF, RO water purifiers remove all commonly found impurities. That’s why they are also known as ‘Universal Water Purifiers.’ Reverse Osmosis (RO) purification is the most reliable water purification technology.

Multi-stage RO purifiers can quickly remove water impurities like mud, sand, bacteria, viruses, and excess dissolved solids like calcium, magnesium, and heavy metals like lead, arsenic, etc.

No other form of home water purification, except RO, can reduce the TDS level of water and eliminate harmful heavy metals like lead, arsenic, fluoride, etc.

Finding the Best RO Water Purifier in India

Every month we spend hundreds of hours researching to come up with a list of the top 10 RO water purifiers.

If you also have the same question in mind, this post will help you find the best water purifier for your home RIGHT NOW!

Best Water Purifier in India (May 2022)

1. HUL Pureit Copper+ Mineral RO+UV+MF Water Purifier

Undoubtedly the Best Copper RO in India

More and more brands are now focusing on the goodness of copper in drinking water.

HUL Pureit recently launched Copper+ Mineral RO. This RO water purifier adds the goodness of copper to purified water.

Pureit Copper+ RO is an advanced 7-stage RO+UV+MF water purifier. It features a unique Copper Charge Technology™ that enriches your purified water with copper in real-time.

HUL Pureit Copper Plus RO

Drinking water from Copper vessels is an age-old Indian tradition that is based on ancient Ayurvedic wisdom. Copper, an essential mineral, improves digestion, helps fight obesity, maintains immunity, and promotes overall well-being.

The manual approach of using a Copper jug to add the goodness of copper to drinking water requires you to store water overnight for 8-10 hrs. Copper vessels are also hard to maintain as they need to be cleaned with lemon juice or baking soda to avoid oxidation.

Key Features

  • Purified water with goodness of copper
  • 7 Stage RO+UV+MF purification: Pre-Sediment Filter, Pre-RO Carbon Filter, Mesh Filter, Reverse Osmosis Membrane, UV Reactor, Post-RO Carbon Filter, and Micro Filter Membrane.
  • Suitable for water from borewell, tanker, and municipal tap
  • 8 liters storage tank
  • Purification capacity of up to 28 liters/hour
  • Purifies water with high TDS up to 2000 mg/l or ppm
  • LED indicators for storage tank empty/full, filter change, and machine error
  • Soft-touch buttons for dispensing Copper Charged RO water and normal RO water
  • Option to add a manual tap that dispenses water without electricity
  • 1-year warranty

Why is it Good?

Most of the Copper water purifiers available in the market today use a copper water tank for adding Copper to purified water. That means you’ll always be drinking Copper-enriched water.

Copper-enriched water offers several health benefits. It is known to boost immunity, improve digestion, help fight obesity, and is very beneficial for overall well-being. In today’s times, everyone is focussing on increasing their immunity. Pureit Copper+ is an easy and intelligent way to add the goodness of Copper to your daily diet.

But like all things, excess copper is also not good for your body. Therefore experts do not recommend drinking copper-enriched water all day long. Two glasses a day is more than sufficient.

We love Pureit Copper+ RO because it gives you an option to dispense purified water with or without Copper.

Pureit Copper+ RO uses a unique technology based on the electrochemical dissolution of copper in water. What it does is it charges RO water with 99.8% pure Copper, in real-time, just before dispensing. So when you press the soft-touch button for dispensing copper-enriched water, the electrochemical reaction adds copper to the water.

The purifier features two soft-touch buttons: one for dispensing Copper-Charged RO water and the other for dispensing normal RO water.

But we have seen one drawback with RO purifiers that have touch controls or soft-touch buttons for dispensing copper water. The touch controls are electrically controlled. Therefore, you cannot dispense copper water (as Copper is added in real-time) in the absence of electricity, even if there is sufficient purified water in the storage tank.

3 Different Ways to Dispense 3 Types of Purified Water – Pureit Copper+

We have provided this feedback to several brands, and luckily HUL Pureit has found a way around this problem. This purifier comes with an innovative feature that lets you install a manual tap on the right side.

This tap lets you dispense normal RO water even without electricity. But we found the manual tap very hard to operate, it requires a lot of effort to turn. It almost feels like the tap might just break with all the force that is required to just turn it on or off.

Why Buy HUL Pureit Copper+?

Another problem with a copper tank-based RO purifier and the copper jug is the inconsistent copper dosing. If the purified water remains in the copper jug or copper tank for a more extended period then the copper enrichment in the water would be higher than that used immediately.

But Pureit Copper+ RO uses advanced technology to ensure that every glass of water contains the right amount of copper. It is possible because, unlike other Copper RO purifiers, Copper+ RO adds Copper in real-time just before dispensing the water.

It seems HUL Pureit has done a fair amount of research and has taken customer feedback very seriously. Pureit has tried to eliminate every possible drawback that the usual Copper RO purifiers have.

Another issue with Copper vessels or RO purifiers with a Copper storage tank is the need for regular cleaning to fight the effects of oxidation. Pureit Copper+ RO comes with an advanced feature that automatically cleans the copper. It makes sure every glass of water is always filled with fresh copper-rich water.

Expert Review

Apart from all the unique and advanced features discussed above, Copper+ RO comes with a big water tank that can store up to 8-liters of purified water. A very high purification capacity of up to 28 liters/hour and a large storage tank makes it suitable for a compact or a bigger joint family.

With Copper+ RO, you can eliminate all the manual effort and still enjoy copper’s health benefits in water.

Pureit Copper+ RO not only looks ultra-modern and beautiful but is also designed keeping the day-to-day functional requirements in mind. If you are someone with an eye for design then this beautiful machine might just be the perfect fit for your house.

You do not need to press and hold the button for continuous flow. One touch of the Soft-Touch button dispenses water continuously for 3 minutes. You can stop the flow of water in between by pressing the Soft-Touch button again, and if you need more water, you need to press the button again.

The advanced filter change alert system alerts you 15 days before Germkill Kit’s life gets over. Auto Shut-off stops water purification if the filter is not changed within time. This feature assures 100% purity of the water.

The water purifier is priced a little higher, and understandably so. Even then, Pureit Copper+ RO has become one of the top-selling RO purifiers on Amazon.in, that too in a very short period of time.

This is the best water purifier for your home if you do not mind spending a few thousand more on buying a water purifier that not only looks beautiful but is functionally brilliant too.

The Got It All RO Purifier

In a very short span of time, Kent Supreme has emerged as the most reliable and one of the best-selling RO purifiers in India. With Kent Supreme, you get reliable and quality purification with the trust of excellent after-sales service from Kent.

Here, we review the top-end variant, the Kent Supreme Extra.

Why is it Good?

Kent Supreme Extra offers 7-stage purification using RO, UF, and UV. Multi-stage purification using RO, UF, and UV makes it ideal for all types of water sources like bore-wells, tanks, or tap water.

Kent Supreme is also suitable for high TDS water and can purify water with TDS as high as 2000 ppm.

The purifier features a transparent cover giving you a complete view of all that works behind it to provide you with 100% pure and safe water. The storage tank can store up to 8 liters of purified water. A large storage capacity and a purification capacity of up to 20 liters per hour make this a good fit for a large family.

Built-in SMPS keeps the purifier completely safe from voltage fluctuations, a common feature in most Indian households.

The Auto-flushing feature prevents scaling of the RO membrane by automatically washing away deposits from the membrane’s surface and keeps the membrane clean. It reduces the amount of rejected water and increases the life and efficiency of the RO membrane.

Why Buy Kent Supreme Extra?

Most RO purifiers remove all essential minerals from the purified water; Kent Supreme uses a TDS controller to maintain a safe level of essential minerals in the purified water.

Filter change alerts & UV fail alarms to keep you updated on when the filters need replacement or any fault in the UV. These features make Kent Supreme a fail-safe water purifier. The purifier stops all operations if the filters are not replaced within the next sixty hours of the alert.

Next in the list of impressive features is the In-Tank UV Disinfection. The UV LED in the storage tank keeps the purified water pure and safe for longer durations.

The Alkaline Booster feature helps in maintaining the pH of the water from 8.5 to 9.5 and thus, provides alkaline and healthy drinking water. The alkaline booster feature addresses the problem of the acidic nature of RO purified water.

Although scientific evidence is limited, various reports have shown that Alkaline water offers several health benefits.

Kent Supreme Extra reduces wastage of water to zero, saving hundreds of liters of water daily. This feature addresses the biggest drawback of using an RO water purifier.

This truly best water purifier is equipped with the ‘Zero Water Wastage’ Technology. This technology sends back the rejected water to the overhead tank, thereby reducing water wastage to zero. It is possible because of a robust internal pump. The pump is powerful enough to push the rejected water to an overhead pump placed even on the 10th floor.

Expert Review

The ‘Zero Water Wastage’ technology’ makes it environment-friendly. In-Tank UV Disinfection, large storage tank, TDS controller, Filter Change and UV fail alert, and a highly reliable purification makes it a great buy.

With Kent Supreme Extra, you get complete peace of mind with a 1 Year Warranty + 3 Years of Free Service AMC, worth Rs. 3,000.

The price may seem slightly higher initially, but with all the great features, especially the ‘zero water wastage,’ Kent Supreme Extra offers the best value for its price.

3. Aquasure from Aquaguard Delight RO+UV+MTDS Water Purifier

Best RO Purifier for Budget Buyers

Key Features

  • RO+UV purification: Sediment Filter, Chemi Block, RO Membrane, UV Disinfection Chamber, and Post Carbon filter.
  • TDS controller for manually adjusting the taste and TDS level of purified water.
  • Suitable for purification of tap/municipal water, or borewell/groundwater with the TDS level from 200 to 2000 PPM.
  • Purifier beeps if UV lamp malfunctions.
  • 7 liters semi-transparent storage tank.
  • LED indicators for Power On, Purification Process On/Off, and Tank full.
  • 1-year warranty.

Why is it Good?

Aquasure Delight features multi-stage purification, which provides 100% clean, safe, and tasty drinking water. It is a combination of the best-in-class purification technologies like RO+UV+MTDS.

This purifier can treat water, having input TDS of up to 2000 PPM. With the reduction of up to 90% TDS, this water purifier ensures safe and tasty drinking water always.

This water purifier comes equipped with the Sediment Filter, Chemi Block, RO Membrane, UV Disinfection Chamber, and Post Carbon filter.

It also features an advanced TDS controller that lets you adjust the taste and the TDS level of the water as per your requirement. This feature ensures you always get sweet tasty water.

As per the specifications, the filter cartridges are designed to last for up to 6,000 liters. So for a family of four, using around 15-20 liters of water daily, the cartridge would last for about a year.

The purifier features 3 LED indicators for Power On, Purification Process On/Off, and Tank full.

As per the manual, the water purifier beeps to alert you when it detects any fault in the UV lamp. This feature is handy, as UV lamp failure can go undetected for a long time. UV lamp failure can result in the presence of harmful micro-organisms like bacteria and viruses in drinking water. This water purifier alerts you when the UV lamp fails, which keeps you and your family 100% safe from water-borne diseases.

Why Buy Aquasure Delight Water Purifier?

Aquasure Delight looks attractive and comes with a semi-transparent storage tank.

The Aquasure Delight water purifier is relatively compact. It can be easily mounted on a wall or placed on a table/kitchen counter. This water purifier easily fits the requirement of your modular kitchen.

Aquasure Delight External Power Adapter
External Power Adapter is Bad Design

But, there is a big design flaw, this machine comes with an external power adapter. In almost all RO purifiers, the power adapter is placed inside, and that is how it should be in Aquasure Delight too. This might be because of the compact size. Whatever may be the case, this external power adapter means one more cable around your purifier. This not only spoils the looks but also takes extra wall space, ultimately spoiling the advantage of compact size.

This water purifier also comes with a large storage tank of 7 liters that ensures you never run out of clean and safe drinking water.

Aquaguard and Aquasure are the most preferred brands of water purifiers in India. After-sales service and quick customer support are critical when it comes to water purifiers. The vast service network, spread over 1500 cities, is quite useful for service and support.

Expert Review

The biggest USP of any Aquaguard/Aquasure water purifier is their world-class water purifiers backed by highly reliable customer service.

Aquaguard has genuinely lived up to its reputation with this fantastic Aquaguard Delight water purifier. If you decide to buy this water purifier, you get all this at a very affordable price.


  • Compact & attractive design
  • Manual TDS controller
  • Clean and compact design
  • Affordable price
  • 7-Liters storage capacity
  • Alerts if the UV lamp malfunctions


  • The power adapter is given outside the water purifier body
  • No alert/indicator for filter change
  • The quality of the dispensing tap could have been better

4. HUL Pureit Eco Water Saver Mineral RO+UV+MF Water Purifier

Highest Water Saving RO in India

HUL Pureit recently launched a new RO purifier ‘Eco Water Saver Mineral’. We were very excited when we first got to know about this product. And after getting our hands on the unit, we are even more excited to bring this review to all our valued readers.

As the name suggests, this water purifier gives you pure and sweet RO purified water, with the highest water saving.

This RO water purifier comes with some unique features. It is India’s first RO purifier that recovers up to 60% water to minimize water wastage. Normal RO purifiers recover only 25-30% water. This means the Eco Water Saver from HUL Pureit reduces water wastage by over 100%, as compared to ordinary ROs.

HUL Pureit Eco Water Saver Mineral RO+UV+MF Water Purifier

Key Features

  • 7 Stage RO+UV+MF purification: Pre-Sediment Filter, Pre-RO Carbon Filter, Mesh Filter, Reverse Osmosis Membrane, UV Chamber, Post-RO Carbon Filter, and Micro Filter Membrane.
  • Suitable for water from borewell, tanker, and municipal tap
  • A large storage tank of 10 liters
  • Very high purification capacity of up to 24 liters/hour
  • The high water recovery rate of appx. 60% means reduced wastage of water
  • Purifies water with high TDS up to 2000 mg/l or ppm
  • LED indicators for storage tank empty/full, filter change, and machine error
  • Automatically shuts-off purification if the filters are not changed in time
  • Free installation and 1-year warranty

Why is it Good?

Pureit Eco Water Saver features an advanced 7-stage RO+ UV+MF purification. This RO purifier is designed to treat multiple water sources be it Borewell, Tanker, or Tap water.

It comes with a mineral cartridge that addresses the problem of de-mineralized water. This mineral cartridge enriches the purified water with essential minerals like calcium and magnesium.

The Eco Water Saver features an advanced alert mechanism that automatically alerts you 15 days before filters & membrane need replacement.

Pureit Eco features a large storage tank of 10-liters. Well, to be precise, that’s not large but very large. This large storage tank is complemented by a high-speed purification of up to 24 liters per hour. This is probably the highest among the leading RO purifiers.

A large storage tank and high purification capacity make it an ideal purifier for big families.

Why Buy HUL Pureit Eco Water Saver Mineral?

Pureit Eco Water Saver features a shiny black exterior with an elaborate LED panel that consists of 4 LED indicators. The LED indicators provide real-time alerts when the tank is full, when the filters need to be replaced, or when there is an electrical fault in the purifier.

The purifier looks a little bulky, but that is understandable as it features a large storage tank.

In addition to the advance filter change alert that we discussed above. This purifier also features an automatic shut-off mechanism.

If you ever forget to change the filters in time, the purifier will intelligently shut off the water purification. While this might seem like a limitation, this is actually a very important feature as it ensures 100% purity of the water at all times.

The purifier is designed in such a manner that it is visually appealing and functionally brilliant.

Expert Review

RO water purifiers have always been criticized for their excessive water wastage.

And the biggest USP of this RO purifier is its high recovery rate. Ordinary RO purifiers offer a recovery rate of just 20-25%.

The Eco Water Saver Mineral, powered by Eco Recovery™ Technology, features a high recovery rate of up to 60%. This is almost three times that of the ordinary RO purifiers.

If you are a family of 5 members and every member consumes 2 liters of purified water daily then Pureit Eco can save nearly 80 glasses (glass quantity of 200 ml) of water daily.

This RO purifier is a great choice not only for homes facing water shortage but for anyone and everyone who feels guilty looking at the RO waste pipe.

Our recommendation on this purifier is very clear, this is an ideal purifier for most Indian homes. Top-of-the-line features like a large storage tank, high-speed purification, advanced filter change alerts, and above all reduced water wastage, all combine to make it the best RO purifier.


  • A very high recovery rate of up to 60% means a reduction in water wastage
  • A large storage tank of 10 liters
  • Very high purification capacity of up to 24 liters per hour
  • Advance filter change alert and automatic shut-off
  • 7-stage RO+UV+MF purification
  • Alerts you in case of any electrical fault


  • Bulky and slightly bigger size

5. Blue Star Aristo RO+UV+UF Water Purifier

Best Value for Money RO

Blue Star Aristo RO+UV+UF Water Purifier

Key Features

  • 7-Stage purification with triple-layered RO, UF, and UV purification
  • Purification capacity of up to 12 liters/hour
  • Storage capacity of 7 liters
  • Indicators for purification on, tank full, and low-pressure alert.
  • Dispensing tap with the child-lock feature.
  • UV-fail alert alerts you in case of UV failure.
  • Attractive design and compact size
  • Aqua Taste Booster feature that maintains optimum pH level, alkalinity and improves the taste of water
  • Comes with a free Pre-filter.
  • 1-year warranty

Why is it Good?

Blue Star Aristo RO+UV+UF is a compact and stylish water purifier. Aristo features a 7-stage purification process: Pre-Filter, Pre-Carbon Filter, Sediment Filter, RO Membrane, Post-Carbon Filter with ATB, UV Lamp, and UF Membrane.

Aristo has a triple-layered purification. The entire water passes through the RO membrane first which removes the dissolved solids. The water then passes through UV purification, the UV lamp kills all micro-organisms to make the water 100% safe. The last stage is the UF membrane which removes the physical impurities and harmful microbes.

It has a high purification capacity of up to 12 liters per hour. The super-efficient and high-quality RO membrane can treat input water with a TDS level as high as 2000 PPM.

The storage tank can store up to 7 liters of purified water. This is more than sufficient for a family of 4-5 members.

The front panel has the standard purification on and tank full indicators along with a low-pressure alert.

Most affordable ROs do not come with a much-needed feature, a UV-fail alert. But luckily, Blue Star Aristo does come with the UV-fail alert. This feature alerts you in case the UV lamp fails. This feature maintains the purity and safety of your drinking water.

Why Buy Blue Star Aristo RO+UV+UF?

The first thing that you’ll notice about this purifier is its clean and compact design. The purifier looks attractive and is compact enough to fit in small kitchens.

One of the distinct features of Aristo is Aqua Taste Booster. The Post Carbon filter with ATB uses calcite media to maintain an optimum pH level and improve the taste of water. An optimum pH level makes the water alkaline which is good for our health.

Aristo also comes with a free pre-filter. A pre-filter filters out all physical impurities bigger than 5 microns and is a must for RO purifiers. It increases the life and effectiveness of internal filters and membranes.

Another distinct advantage that the Aristo offers is the child-lock feature on the dispensing tap. The dispensing tap will not work when the child lock is on. This prevents any accidental wastage of water. This feature is especially good if you have small children in your family.

Expert Review

Aristo comes with all standard features that any good RO water purifier should have. It also features some distinct and very useful features like Aqua Taste Booster, Child-lock, and UV fail alert.

6. Eureka Forbes Aquasure from Aquaguard Amaze RO+UV+MTDS Water Purifier

A strong contender in the reliable and affordable RO segment

Aquasure Amaze is the latest in the line of affordable RO water purifiers from Eureka Forbes.

Aquasure Amaze is one of the most selling RO purifiers on Amazon.in. One apparent reason for its massive popularity is the affordable price.

But, is there more to its popularity apart from its affordable price?

Let’s find out.

Aquasure Amaze RO+UV+MTDS Water Purifier

Key Features of Aquasure Amaze

  • RO+UV purification with the TDS controller for adjusting the taste and TDS level of the purified water.
  • Suitable for purification of tap/municipal water or borewell/groundwater with the TDS level from 200 to 2000 PPM.
  • Clean and compact design.
  • Automatically alerts you in case of UV failure.
  • 7-liters semi-transparent storage tank.
  • LED indicators for purification on/off, tank full/empty, and power on/off.
  • 1-year warranty

Why is it Good?

Aquasure Amaze features 5-stage purification: Sediment Filter, Chemi Block, RO Membrane, UV Disinfection Chamber, and Post Carbon filter. These are the most basic purification stages that any RO purifier features.

This purifier doesn’t come with an external pre-filter. A drawback that you must consider as we recommend installing an external pre-filter. An external pre-filter increases the life and efficiency of all the internal filters and membranes by filtering out the physical impurities like dust, sand, mud, etc.

The combination of purification technologies like RO+UV provides clean and safe water. MTDS or TDS controller is an additional benefit that lets you adjust the taste and the TDS level of the purified water as per your need.

Though we are not big fans of the TDS controller technology, it has one distinct advantage. This technology makes the RO purifiers suitable for even low TDS level water.

Wondering how? Using the TDS controller, you can control what percentage of water is RO purified. If you want to know how that’s possible, please read our detailed post on the TDS controller and how it works.

Suitable for purifying water from all sources, Aquasure Amaze is ideal for purifying water with a TDS level between 200 to 2000 PPM. With the reduction of up to 0% to 90% TDS, this water purifier ensures safe and tasty drinking water consistently.

Six thousand liters of filter life means trouble-free and cost-effective maintenance. For a family of four, using around 15-20 liters of water daily, the filters would last for about a year.

The purifier features 3 LED indicators placed just below the storage tank. The indicators provide helpful information like power on/off, purification process on/off, and tank full/empty.

Why Buy Aquasure Amaze Water Purifier?

Looking at the design, you instantly feel that this RO machine will easily fit in the tiniest of kitchens.

That’s true. Amaze is one of the most compact RO machines in India. The compact design, shiny dark grey finish, and semi-transparent storage tank give it a pretty look.

It can be easily mounted on a wall or placed on a table/kitchen counter. While most RO purifiers can be wall-mounted or placed on a table/kitchen counter, a compact RO like Amaze sits comfortably on the kitchen counter and does not look awkward.

Most RO machines that are as compact as the Amaze come with a tiny storage tank of 5 or 6 liters. But you’ll be pleasantly surprised to know that this water purifier features a sufficiently large storage tank of 7 liters. A 7 liters storage tank is sufficient to meet the drinking water requirements of most Indian homes.

You should also be aware of one design flaw. The power adapter, which is kept inside and is not visible, is given outside the box. It is because of the ultra-compact design, which leaves very little room inside. It doesn’t impact the machine’s performance in any way, but some users may not prefer this.

We were a little surprised when we learned that the Amaze comes with the much-needed yet often overlooked feature of UV-fail alert.

The team of experts at BestROWaterPurifier has always believed that this feature should be made mandatory by the Bureau of Indian Standards (BIS) in all water purifiers with UV purification.

UV lamps, like any other electronic part, are prone to failure. And unlike filters/membranes, which get choked over time and give a signal of replacement, there is no other way to know if the UV lamp is working fine or not. A UV lamp is the most neglected part of a RO machine, as most service engineers do not care to check it even while servicing.

UV lamp failure can go undetected for a long time and result in harmful micro-organisms like bacteria and viruses in drinking water.

Luckily, this RO machine automatically beeps to alert you when it detects any fault in the UV lamp. This one little feature keeps you and your family safe from water-borne diseases.

Expert Review

Aquaguard and Aquasure are the most preferred brands of water purifiers from the house of Eureka Forbes. The biggest USP of any Aquaguard/Aquasure water purifier is its highly reliable customer service.

A good RO machine is of little value if you have to struggle for its parts and proper maintenance. No brand can claim 100% customer satisfaction, but the vast service network, spread over 1500 cities, is a considerable assurance of timely service and support.

Aquasure Amaze features almost an identical design, features, and water purification technology as the Aquasure Delight.

The dimensions, design, size, storage capacity, and purification stages are precisely the same as the Aquasure Delight.

The only visible difference is the color of the water purifier and the sticker on the water tank just above the dispensing tap.

So why would you buy Aquasure Amaze and not Aquasure Delight?

Aquasure Amaze is a few hundred rupees cheaper than the Aquasure Delight. If you are someone who would prefer dark metallic grey color over the evergreen white color of Aquasure Delight, then you may want to choose Aquasure Amaze.

This RO machine comes with all the essential features, is compact, looks attractive, and above all, comes at a very affordable price.

If you are looking for a reliable yet affordable RO, this is a strong contender.

Livpure Glo not only gives you clean and pure water but also adds back required essential minerals like Calcium, Magnesium, Sodium, and Potassium.

RO purification is undoubtedly the most reliable form of purification but RO purified water can sometimes be a little acidic. RO purification, along with the tiniest of impurities, removes most essential minerals. This lowers the pH value and makes the water acidic. The Mineralizer cartridge adds back the essential minerals and lowers the acidic nature of water, to give you purified water that has the right pH level.

Livpure Glo is ideal for all types of water sources and effectively removes all commonly found impurities in water. It can treat input water with high TDS levels of up to 2000 ppm.

Why Do You Need a Water Purifier?

According to a report from the Ministry of Drinking Water and Sanitation, Govt. of India. It is estimated that about 37.7 million Indians are affected by waterborne diseases. 1.5 million children die of diarrhea and 73 million working days are lost due to waterborne diseases annually, leading to an economic burden of USD 600 million a year.

Data published by the Ministry of Drinking Water and Sanitation (MDWS) reveals some shocking facts. Out of the total 17, 13,303 habitations in India, 1, 40,437 were found to be contaminated as per lab tests conducted in FY 2017-18. It accounts for 8.19 percent of all habitations being affected by low water quality.

It is estimated that 66 million people in 20 Indian states are at risk due to excess fluoride and 10 million due to excess arsenic in the groundwater (report). About 62 million people are suffering from various fluorosis levels, of which 6 million are children below 14 years; suffering from dental, skeletal, and non-skeletal fluorosis.

These reports are alarming; the state of water contamination in India necessitates that almost every home in India adopts one or the other water purification measures.

How to Find the Best Water Purifier for Your Home?

The most authentic, comprehensive, and most reliable piece of information that you would find anywhere on the Internet about ‘things to look for when buying a water purifier.’

The following information would prove very useful if you are buying a water purifier for the first time. Most first-time buyers are confused and unsure of what to look for before purchasing a new water purifier.

We have tried to keep this guide as brief as possible while ensuring that you do not miss out on any vital information.

1. Source of Water

It is the first and one of the most important things that you should look at when you plan to buy a new water purifier for your home or office.

The most common sources of drinking water in India are:

  • Municipal Corporation Supply
  • Borewell/Groundwater
  • Rivers
  • Lake/Ponds

Each water source contains different types of impurities and therefore requires different kinds of purification.

In the following point, you will see why knowing the source of drinking water is so important.

2. Types of Impurities

Unfortunately, there is a wide range of impurities that can contaminate your drinking water.

Water that looks visually clean may contain several harmful impurities.

The below table lists down the most common impurities according to the water source.

Source of Water Common Impurities
Municipal Corporation Supply Visible impurities like mud, sand, rust, etc.

Invisible impurities like:
Bacteria & Viruses

Borewell/Groundwater Visible impurities like mud, sand, etc.

Invisible impurities like:
Dissolved Salts like Calcium, Magnesium, etc.
Harmful heavy metals and chemical impurities like Lead, Arsenic, Fluoride, Mercury, etc.

Rivers Visible impurities like mud, sand, etc.

Invisible impurities like:
Dissolved Salts like Calcium, Magnesium, etc.
Harmful heavy metals and chemical impurities like Lead, Arsenic, Fluoride, Mercury, etc.

Lake/Ponds Visible impurities like mud, sand, algae, etc.

Invisible impurities like:
Very high level of Bacteria & Viruses, Protozoa, Cysts, etc.

Visible impurities, like mud, sand, duct, etc., are easily identifiable because they can either be seen in the water or result in water discoloration.

Chlorine, the most commonly used chemical disinfectant, leaves a characteristic smell and bitter taste.

Micro-organic impurities, like bacteria, viruses, cysts & protozoa, can neither be seen nor leave any identifiable smell or taste. Do you or any of your family members frequently suffer from waterborne diseases? Diseases like diarrhea, Typhoid fever, loose motions, etc., generally spread because of microbial contamination.

You can easily find the level of Total Dissolved Solids using a digital TDS meter. But there is a big catch here that is discussed in detail in the following point.

3. TDS Level of Water

TDS (Total Dissolved Solids) represents the total concentration of all the dissolved substances in water. Dissolved solids can easily pass through a filter with 2-micrometer (or smaller) pores.

Finding the water’s TDS level is the most basic and primary requirement that gives you preliminary information on how contaminated the water may be.

Finding the TDS level of water is very easy and takes a few seconds only. All you need is a digital TDS meter like this one.

Digital TDS meters are readily available online and that too at highly affordable prices.

The TDS level is measured in PPM (Parts Per Million) or mg/L. It gives you a clear idea of all the dissolved solids in your drinking water.

As revealed at the end of the previous point, the big catch here is, while the TDS meter tells you about the level of all the dissolved solids, it does not tell you:

  • What all dissolved solids are present?
  • The concentration/level of each dissolved solid.

Unfortunately, finding the individual constituents (and their exact concentration) that make up Total Dissolved Solids in water is not straightforward.

It requires you to get the water sample tested by a professional or in a water testing lab.

But, what is the need for finding the individual constituents of TDS?

A significant portion of the TDS level consists of harmless salts and minerals like Calcium, Magnesium, and Sodium.

But, some dissolved solids are hazardous even in low quantities. These include arsenic, fluorides, and nitrates.

Do you live in an industrial zone or an agricultural region known for the abuse of pesticides and chemical fertilizers? If yes, then there is a high probability that these harmful contaminants may have entered the groundwater or river stream.

The drinking water standard that applies to India is BIS 10500-2012.

As per the BIS Standard, the maximum desirable TDS level is 500 mg/L. The maximum permissible TDS level in the absence of a better source of water is 2000 mg/L.

But it is important to note here that there are different standards for the acceptable amounts of harmful contaminants like Arsenic, Fluoride, Arsenic, Nitrates, etc., in water.

It answers your question ‘why knowing individual constituents of TDS is important’, especially if you live in an industrial zone.

Let’s now see the practical implication of how impurities and the TDS level of the water help you decide which purification technology to use.

4. Purification Technology

We will not be discussing each of the water purification technologies here just for the sake of keeping this guide short and concise.

You can refer to our detailed water purifier buying guide for all that information.

The table below shows the ideal water purification technology according to the TDS level and type of impurities.

Important Note: If the water contains any heavy metal or harmful chemical impurities, like lead, arsenic, fluoride, nitrates, etc., there is no other option but to use a water purifier with RO purification. It is because no other water purifier can get rid of these harmful impurities.

Like most people, if you are not sure of the kind of impurities (except for the TDS level and visible impurities), then it is always advisable to go for a Universal or multi-stage RO water purifier.

The Universal water purifier is a term used for multi-stage RO+UV+UF water purifiers. They are called universal water purifiers because they can filter out all the commonly found impurities in drinking water.

TDS Level Is Water Muddy? Presence of Biological Impurities? Ideal Choice
Below 500 ppm No No Gravity-Based Purifiers
Below 500 ppm No Yes UV Purifiers
Below 500 ppm Yes No UF Purifiers
Below 500 ppm Yes Yes UV+UF Purifiers
Over 500 ppm No No RO Purifiers
Over 500 ppm No Yes RO+UV Purifiers
Over 500 ppm Yes No RO+UF or RO+UV+UF Purifiers
Over 500 ppm Yes Yes RO+UV+UF Purifiers
Identifying the Water Purification Technology on the Basis of Water Quality

5. Purification Capacity

Purification capacity, mostly specified in liters/hour, is the quantity of purified water that a water purifier produces in an hour. Most of the RO water purifiers feature purification capacity anywhere from 12-15 liters/hour. But some high-end models offer a purification capacity of up to 20 liters/hour or even higher.

Understanding the drinking water requirement as per your family’s size will help you find out the ideal purification capacity you need.

The purification capacity of 12-15 liters/hour is ideal for most Indian households.

6. Storage Capacity

Apart from some UV water purifiers, most other types of water purifiers come with a storage tank for purified water. It allows you access to purified water at all times.

Water purifiers feature storage capacity ranging from 7 liters to 12 liters.

Suppose you have a bigger family or long power cuts in your area. In that case, you should go for a water purifier with a bigger storage tank.

Any water purifier with a storage capacity of 7-liters or higher is suitable for most Indian homes.

7. Tank Type

The material of the storage tank also plays an important role as it stores purified water.

That is why almost all water purifier brands provide ABS food-grade plastic or stainless steel tanks to ensure purity and durability.

All you have to make sure is you should properly seal the tank to avoid any external contamination.

8. Indicators & Alerts

Indicators & alerts are an essential yet most overlooked feature in water purifiers.

Just imagine for a second that the UV lamp of your UV/UV+UF or RO+UV malfunctions, and the purifier continues to dispense water.

Without a UV fail alert/alarm, you do not have any way to know whether the UV lamp is functioning or not.

Similarly, some filter change alerts notify you when the filters need to be replaced.

Standard indicators like the ones for purification-on and the tank full are also handy. The purification on/off indicator shows whether the purification process is on or off. The tank full indicator shows whether the water storage tank is full or empty.

9. Type of Installation

Depending on the availability of space and personal preference, you can go for a water purifier that can either be placed on the counter or mounted on the wall.

Most RO water purifiers offer dual installation, i.e. both counter-top and wall-mounted installation.

If you neither have space on the kitchen counter nor the kitchen wall, then you can go for a space-saving under-sink water purifier. Under sink water purifiers can be easily installed below the sink of your kitchen.

10. Water Recovery / Water Wastage

All RO water purifiers waste water during purification. While some waste as much as 75-80% of the input water, some newer models recover over 50% of the input water.

Looking at the global water crisis, it is crucial that you only buy an RO water purifier when it is required. Don’t buy an RO water purifier if the water’s TDS level is below 500 PPM and the water does not contain any harmful chemicals or heavy metals.

Non-RO water purifiers, like gravity-based, UV, or UV+UF water purifiers, do not waste any water.

If you are buying an RO water purifier, go for brands and models that offer a higher water recovery ratio.

Features like child lock on tap also prevent accidental wastage of water.

11. Warranty & After-Sales Service

Water purifiers require regular maintenance and after-sales support. Therefore, you must choose a brand that offers good customer support.

Apart from the after-sales support, it would be best if you look for the initial warranty.

Go for reputed brands with a well-established customer service network and a minimum warranty of 1 year. You can also look for products and brands that offer extended warranties.

12. Price

Like with all purchases, price is an essential factor when you are buying a new water purifier.

Water purifiers (Gravity-Based) start from as low as Rs. 1,500 and can go up to as high as Rs. 40,000, or even more.

But, when buying a water purifier, price shouldn’t be the first criterion in your buying decision. That’s because the safety of your family is always more important than saving a few hundred or a few thousand rupees.

Luckily, like mobile phones and LED TVs, water purifiers have become cheaper over the years. You have many choices, and the price for some of the best-selling six or 8-stage branded RO water purifier starts from as low as Rs. 8,000.

Frequently Asked Questions (FAQs)

1. Which water purifier is best for Borewell water?

Borewell water generally has a high TDS level. Apart from the commonly found minerals like calcium, magnesium, sodium, iron. Borewell water may also contain several harmful heavy metals like mercury, lead, arsenic, fluoride, etc.

Reverse Osmosis filters are most suitable for high TDS water. RO purification combined with UV purification is ideal for borewell water as UV provides extra protection from biological impurities like bacteria and viruses.

You can also use UF or Gravity-based purifiers for borewell water that does not have any harmful impurities and TDS levels less than 300 ppm.

If you do not have any budget constraints, then RO+UV water purifiers are the safest bet for borewell water purification.

2. Which brand offers the best customer service and after-sales support?

A water purifier is one product that requires periodic service and technical support. Therefore it is crucial that you only buy water purifiers from reputed brands with good customer support services.

All leading brands are now focussing on providing better after-sales support. Still, before buying any particular brand, you should always check whether the brand:

a) offers free installation in your area.
b) has distribution and support services in your area.

You can check all this by simply calling the customer support number of the respective brand. You can also perform a local search on Google or read user reviews on websites like JustDial and online stores like Amazon and Flipkart.

We say this because some brands may provide excellent service in some parts and not so good service in other parts of the country.

3. I am getting a non-branded RO at half the price, should I buy it?

We do not advise our readers to go for a local brand or non-branded water purifiers. Water purifiers are meant to provide you with pure and clean drinking water and keep you safe from harmful waterborne diseases.

These non-branded water purifier machines are very cheap, and you may be tempted to buy one. Still, you should always invest in a good quality water purifier from the best brands. Cheap non-branded purifiers:

a) use low-quality filters and membrane
b) have poor customer support service
c) offer unreliable purification

4. What is the benefit of buying a water purifier online?

If you buy a water purifier from a reliable online store like Amazon or Flipkart, then you can expect benefits like:

a) 100% genuine product
b) free installation by the brand
c) free extended warranty or extra warranty at a very low price
d) attractive price, best deals, and offers
e) bank and credit card discounts
f) you can compare water purifiers from different brands and buy from the comfort of your home or office
g) read customer reviews to make a confident choice

5. Will I get the free installation and warranty if I buy a water purifier online?

Yes, you get the complete brand warranty and free installation as you would get when you buy from a brand’s local authorized dealer. But you should always take care of three things while ordering a water purifier online.

a) Always buy from trustworthy websites like Amazon and Flipkart because the sellers on these online stores are verified. They have robust customer protection policies.
b) Check the installation and warranty details on the product page.
c) Check the seller ratings and user reviews to be 100% sure.

You may even get the extra or extended warranty at a minimal price if you buy online during some offer period.

6. What is the maintenance cost of an RO water purifier?

All RO water purifiers require periodic maintenance, consumable parts like filters, and membrane replacement at regular intervals. Replacement of these parts and filters ensures the purity of water. It maintains the efficiency and effectiveness of your RO purifier.

Most reputed brands of water purifiers now offer standard AMC packages. These AMC packages generally cover all consumables, electronic parts, and periodic servicing. Different brands have different rates for their AMC packages, and AMC packages can also vary according to the water purifier model.

Generally, AMC packages start from Rs. 4,000 and can go up to Rs. 8,000 depending upon the brand and water purifier model. AMC packages for high-end water purifiers with a lot of extra features tend to be higher.

7. Why do RO water purifiers waste so much water?

Reverse Osmosis (RO) purifiers use membrane technology to filter dissolved impurities. RO membranes have hundreds of holes as small as 0.0001 microns that only allow water to pass through and filter out everything else. The impure water is filtered out and is often called wastewater or reject water.

The percentage of wastewater varies based on the water quality/TDS and RO purifier being used.

An average RO purifier produces approximately 3-liters of wastewater for every 1-liter of purified water. It means only 25% of water is purified, and 75% of water comes out as waste. However, as a responsible citizen, you should not send this wastewater or reject water down the drain. This RO wastewater can be used for several other home tasks.

The latest RO water purifiers feature a recovery ratio of up to 50%, significantly reducing the RO wastewater.

8. Is RO water purifier good for health?

It is a well-established fact that RO water purifiers offer the most reliable water purification. But the issue with RO purifiers is they do not discriminate between impurities and essential minerals. It means that while removing most impurities, RO purifiers also remove some essential minerals like Calcium and Magnesium.

Some experts believe that long-term consumption of completely demineralized water is bad for human health if not compensated by what you eat.

At present, there is no other technology that provides such reliable water purification as RO purification.

Also, you need not worry so much about demineralization as long as the TDS level of the input water is more than 500 ppm. And even if the input water’s TDS level is below 500 ppm, you can choose a good RO water purifier with a mineralizer or TDS controller.

Also, if the input water contains harmful heavy metals like lead and arsenic, there is no other option as no other purification technology can remove them.

RO water purifiers will not have any adverse effects on your health if you make the right choice. If you do not want to compromise on your family’s health, you should only invest in a quality RO water purifier from a reliable brand.

9. What should be the TDS level of RO Water?

If you are drinking RO purified water, then make sure the TDS level of purified water is not too low. Purified water with a TDS level below 50 mg/L is not considered healthy. We recommend that the TDS level of RO purified water should be in the range of 80-150 mg/L. You can read more about finding the TDS level and the ideal TDS level of drinking water.


Different sources of water with varying impurities may require different types of water purifiers. We have put together a detailed water purifier buying guide to help you identify the right water purification technology for your home or office.

It brings us to the end of this very long and detailed review of India’s best RO water purifiers. We hope you enjoyed reading this informative and useful post.
