Before you buy a water purifier, make sure you check the TDS levels in your water source. If the TDS is above 300ppm RO water purifier is required, if the TDS is below 300ppm, a UV UF water purifier will suffice.

How did we test these models?

best water purifier in india

We purchased and installed these models in our office and home kitchens. We chose our water purifier model according to the water source quality.

We connected the RO water purifier to the groundwater source and the UV water purifiers to the water source supplied by the municipality.

We tested each model for one year before reviewing its performance, features, pros, and cons.

Aquaguard vs Livpure

Besides testing their performance levels, we checked the longevity of the filters and membranes. That gave us an idea of each model’s maintenance costs and AMC pricing. In addition, we experienced first-hand the services offered by the top water purifier manufacturers.

Best Water Purifiers in India

1. HUL Pureit Eco Water Saver

HUL Pureit ECO Water Saver

This RO is the best water-saving model in India suitable for a Large family. If budget is not your criteria, you can go with this model

Pros

  • The water purifying performance is excellent.
  • This machine reduces water wastage considerably.
  • The filter change indicator is handy.
  • The HUL Pureit machine consumes less power than other RO water purifiers.
  • Excellent design and good storage capacity

Cons

  • High maintenance costs
  • It needs a pressure-enhancing attachment if water pressure is below 10psi.
  • Customer service needs improvements.

Water wastage is the prime drawback of any RO water purifier. While RO water purifiers can remove TDS up to 2000 ppm, they waste a lot of water in the bargain. So any RO water purifier that promises less wastage becomes instantly popular.

The HUL Pureit Eco Water Saver appliance is ideal because the manufacturers claim this machine reduces water wastage by 60%. However, the water wastage percentage depends on the TDS levels. The lower the TDS levels, the lesser the wastage.

Comparing it with other RO water purifiers, we found the HUL Pureit Eco Water Saver to be better. Otherwise, the water purification technology is the same as other RO water purifying appliances.

Instead of a TDS controller, this machine uses a mineral enrichment cartridge to replenish lost minerals like magnesium and calcium. This appliance can handle up to 2000 ppm TDS levels to purify all water sources.

The 10L water storage tank is sufficiently large to cater to the requirements of large-sized Indian families. The water purification rate depends on the TDS levels. During our testing with 800ppm TDS levels, the tank got filled in 30 minutes.

The wastage was around 8.5L for every 10L of water purified. The reject water had around 1100ppm TDS, whereas the RO-purified water had 150ppm.

The Germkill kit replacement indicator is handy because it alerts us beforehand to change the cartridge. Besides, the machine stops working when the filtering power gets exhausted. This safety feature is of the HUL Pureit Eco Water Saver purifier’s highlights.

The storage tank does not have a transparent window to ascertain its water levels. Instead, it has an LED indicator that flashes only when the tank gets filled up. Otherwise, you cannot estimate the water levels in the tank.

Maintenance costs are high, especially with the Germkill kit costing around Rs 3,000. Another drawback is that the machine cannot purify water when the source pressure is less than 10psi or above 30psi. So it would be best to have a pressure-enhancing pump or a pressure-reducing valve.

Drawbacks will be present in every RO water purifier. However, while the maintenance costs are high at almost 50% of the machine’s price, this HUL Pureit Eco Water Saver RO water purifier is one of the best for under Rs 15,000.  

2. Sure from Aquaguard Delight NXT

Sure From Aquaguard Delight

This RO is the best budget model but it wastes water and comes with a TDS Controller

Pros

  • Adequate storage tank capacity of 6 liters
  • 8-stage water purification and excellent performance
  • Budget-friendly appliance and stylish looks
  • Sensors and LED indicators are handy features.
  • Free AMC for the first year

Cons

  • Water wastage is usually observed in all RO water purifiers.
  • High maintenance costs
  • Ordinary after-sales services

Usually, RO water purifiers are expensive when we go shopping for them in offline stores. Sure from Aquaguard Delight NXT is the best budget RO water purifier as it is available for under Rs 9000 in e-commerce retail stores like Amazon. This budget-friendly water purifier is ideal for small and medium Indian families.

Read More

We advise checking TDS levels in the source water before finalizing your water purifier because TDS levels below 400 ppm do not require RO water purification. But this product from Eureka Forbes is an ideal choice on a low budget because it offers multiple water purification technologies like RO, UF, UV, and carbon filtration.

Besides, the I-filter removes suspended impurities, and the Chemi-Block filtration arrangement removes chlorine and other VOCs to enhance the water taste.

Water wastage is a recurring problem with all RO water purifiers. Still, the product manual of the Sure from Aquaguard Delight NXT says that it uses advanced water purification techniques to reduce water wastage by 60%. However, we tested the machine and found it is more of a marketing gimmick. Nevertheless, water wastage depends on the TDS levels in the input water source.

Sure From Aquaguard Delight sound

Besides the regular RO, UF, and UV water purification, this machine offers a Taste Adjuster feature, MTDS, to adjust the water taste depending on the water source. It is like the TDS controller feature offered by Kent and other machines.

Reintroducing raw water to the RO-purified water can re-contaminate it, but it replenishes the lost minerals like calcium and magnesium. However, tweaking the MTDS feature requires technical expertise, and consumers cannot change the setting after they fix it. Instead, the technician must reopen the machine and adjust the levels.

This machine does not occupy much space in the kitchen as you can mount it near the water source. It is beneficial because the water purifier cannot work if the pressure is lower than 5 psi. LED alerts are excellent features because you know when the filters and membrane need replacement.

The maintenance costs are high at around Rs 4,500. Depending on the water source quality, the filters, and RO membrane require frequent replacements. A free AMC is available for the first year.

Despite the drawbacks, the Sure from Aquaguard Delight NXT is a popular water purifier available at a reasonable price. So it is the best water purifier available at budget prices in India.

3. Kent Supreme Alkaline Water Purifier


Kent Supreme Alkaline

Good RO Water purifier and gives water a taste that is similar to Mineral water because of the Alkaline booster.

Pros

  • The purification performance is excellent but is better suited for water with moderate TDS levels.
  • The attractive design adds to your kitchen’s ambiance.
  • The in-tank UV-LED feature is innovative.
  • The silent operation and 8L storage capacity make it an excellent choice for medium-sized Indian families.

Cons

  • The maintenance and AMC costs are high.
  • Zero water wastage is a misleading claim.
  • The sediment filter is not part of the package.
Kent Supreme Alkaline water purifier review

Kent Supreme Alkaline water purifier differs from its contemporaries because it claims to increase alkaline content in water to make it taste better.

RO water purifiers are excellent for removing TDS and heavy metal impurities. Besides, they can also eliminate bacteria and viruses. However, removing the TDS entails removing essential salts, as well. So, the RO-purified water has pH levels bordering 7, which is neither acidic nor alkaline. So, the water does not taste good.

Read More

Kent Supreme Alkaline water purifier sets this anomaly right by introducing alkaline content into RO-purified water and making the water slightly alkaline and taste better.

Kent Supreme Alkaline RO

This water purifier has similar components to any other Kent RO water purifier, save for the Alkaline booster. It contains mineral balls that leech essential minerals like silica, calcium, copper, etc., to RO-purified water to increase its pH value and make it alkaline.

Performance-wise, this water purifier is like other Kent RO water purifiers because it uses the TDS controller mechanism to replenish the essential minerals lost during the RO water purification process.

TDS of Kent Supreme Alkaline water

The process is fine if the source water does not contain heavy metal impurities and contaminants like arsenic, lead, and mercury.

Another common problem with this Kent Supreme Alkaline water purifier is water wastage. Like all RO water purifiers, this model also wastes much water. But Kent has introduced a solution to reuse the rejected water by pumping it back to the overhead tank for recirculation.

This zero-water wastage claim is more of a misnomer because the machine does not eliminate water wastage.

A better solution would have been to collect the rejected water in 10/20L water cans and use the water for watering plants, washing bathroom floors, etc.

Kent Supreme RO review

After RO purification, we checked the TDS levels and found them to be around 150 ppm. That should be ideal by WHO and BIS recommendations.

One excellent feature observed in this water purifier is the in-tank UV-LED purification to ensure that the RO water retains its purity until the consumption stage by eliminating recontamination of purified water by bacteria and viruses.

While the performance is excellent, the maintenance costs are high at around Rs 5000 to Rs 5500 annually. The AMC costs somewhere in this price range. Therefore, I recommend users take an AMC because it includes the cost of replacing filters and membranes.

The pricing is reasonable compared to similarly equipped RO water purifiers on the market. However, Kent could have included the sediment filter and pipe fittings in the original package.

4. HUL Pureit Vital Max

Pureit Vital Max

Good and Compact RO that comes with a Modern Design and is suitable of all kinds of water sources.

Pros

  • Good water purification performance
  • Sleek looks and compact appearance
  • Smartsense indicators are handy.
  • The machine wastes less water than other RO water purifiers.

Cons

  • This machine is expensive compared to other RO water purifiers.
  • Maintenance costs are high but unavoidable.
Hul pureit vital plus max review

Installing this machine does not require any elaborate process. The company offers free installation, with the technician demonstrating its operations after the installation. The machine has a compact design and appearance that suits your kitchen ambiance. Depending on your customized preferences, you can wall-mount it or place it on the counter.

Read More

Performance-wise, it is good and compares with other RO water purifiers. HUL claims that its FiltraPower technology kills bacteria and removes toxic chemicals, but it is not innovative because all UV lamp-equipped water purifiers perform similarly.

HUL also claims that its Eco Recovery technology saves water wastage by 60%. It is partially true because we have tested this machine, and the water wastage percentage is less than contemporary water purifiers.

This water purifier can handle TDS levels up to 2000 ppm. So, it is ideal for purifying all types of domestic water sources like Borewell water, overhead tanks, and tap water. Besides, this appliance features a Mineralizer attachment to replenish the lost minerals in RO-purified water. This feature is better than the TDS controller offered by Kent RO.

HUL claims that this machine requires less maintenance, but much depends on the TDS levels in the water source. The RO membrane and filters require replacement every 18 to 24 months. These components are expensive. Besides, the mineralizer cartridge needs regular replacement. So the maintenance costs are like any other RO water purifier.

Features like Smartsense indicators are useful because they alert users about replacing the filters a fortnight in advance. Secondly, the machine stops functioning after the filters lose their potency. So it caters to the hygiene factor well. Finally, the mineralizer and RO membrane can function up to 6000L of water purification.

The 7L storage tank is sufficient to satisfy the requirements of the average Indian family. The water purification rate is excellent at 24L per hour on average. However, much depends on the TDS levels present in the water source. The water storage tank is made of engineering-grade, non-toxic plastic. Hence, it lasts long.

5. Livpure Glo Pro++

Livpure Glo Pro++

This Livpure RO gives a better taste to water as it comes with a Mineralizer instead of a TDS Controller

Pros

  • It can handle all water types, even with TDS levels up to 2000 ppm.
  • Exciting design with excellent operational indicators
  • The Taste Enhancer feature improves water taste after RO purification.
  • This machine is priced reasonably.

Cons

  • Water wastage is a common drawback of all RO water purifiers.
  • The after-sales services need improvement.
  • No pre-filter with the package

Homes depending on groundwater, Borewell or other resources deal with high TDS levels reaching 2000 ppm. This Livpure Glo Pro++ water purifier can handle all water types and deliver pure water for daily consumption.

Read More

The versatility of the Livpure Glo Pro++ design makes it the most convenient to install. You can place the machine on the kitchen counter or mount it on the wall according to your preferences. Unfortunately, the tap design is faulty because we experienced water dripping after releasing the lever. A convention tap design could have been better.

While Livpure does not offer the best after-sales services, especially for installation, the company offers a decent warranty and AMC facilities. However, RO water purifiers are expensive to maintain because of regular filter and membrane replacements.

In addition, Livpure does not offer a pre-filter with the package. But We advise people to purchase one separately because it traps suspended impurities and protects the RO membrane.

Livpure RO

Features-wise, this machine is no different from other RO water purifiers concerning RO water purification. However, it features a unique Taste Enhancer facility to improve water taste after RO purification.

Besides, the UV disinfection feature destroys bacteria and ensures 100% purified water. Furthermore, silver-impregnated membranes ensure high-quality water purification.

The 7L water storage tank is a handy feature and ideal for small Indian families. In addition, this water purifier takes around 15 to 20 minutes to fill the water tank. Exciting features include Power-On, tank-full, and water purification indicators.

Maintenance costs are high because the RO membrane is expensive. Regular replacement is necessary every 12 to 24 months, depending on the input water source TDS levels.

While the Livpure Glo Pro++ functioning and performance is not different from other water purifiers, the Taste Enhancer feature is better than the TDS controller Kent RO offers. This feature does not re-contaminate the purified RO water but adds essential minerals. Hence, this kitchen appliance is the best water purifier for Rs 10,000.

6. Kent Grand Plus


Kent Grand Plus

Good RO Water purifier and gives water a taste that is similar to Mineral water because of the Alkaline booster.

Pros

  • The overall water purification performance is of the highest quality.
  • The 9L water storage tank is sufficient for the average Indian household.
  • The in-tank UV-LED purification feature is a well-thought-out idea to retain water purity until the final consumption stage.
  • This machine has an excellent purification capacity of 20L/hour.

Cons

  • Zero water wastage claim by Kent is a dampener.
  • The package does not include a sediment filter.
  • High maintenance costs can deter many users from choosing Kent RO water purifiers.
Kent Grand Water Purifier review

Kent Grand Plus is like the Kent Supreme Alkaline water purifier in many respects but without the capacity to make the water alkaline.

Water wastage is inevitable in the RO water purification process. There is no way for the machine to drain harmful TDS from the source water without wasting water.

Read More

Performance-wise, there is little to choose between the Grand Plus and other Kent RO water purifier models. The purification stages are the same. The only addition is the introduction of UV-LED water purification in the storage tank. The latest Kent RO water purifiers, like the Kent Supreme Alkaline, also have this feature.

Kent Grand plus ro water purifier review

The TDS controller mechanism is Kent’s USP to enhance the output water’s taste. It is okay if the TDS in the original water source does not contain heavy metal impurities. Otherwise, it can be risky because the TDS controller introduces the source water after the RO water purification process. This water retains all the minerals (good or toxic) to mix with RO-purified water, enhance its TDS levels, and improve its taste.

So, this machine is a big NO if you live near industrial areas where metal impurities can be critically high. But it is a good measure if you live in areas with source water having moderate TDS levels.

Kent Grand water purifier review RO

While the Kent Supreme Alkaline features an Alkaline Booster, the Grand Plus model has a post-RO activated carbon filter to remove residual organic impurities and improve the water taste.

We have tested the water purification performance and found it excellent at 20 liters per hour. However, this value depends on the TDS levels in the original water source.

Kent Grand RO inside

The maintenance costs are high, as you observe in almost all RO water purifiers. But We recommend you take an AMC costing around Rs 4000 to Rs 5000. It is a better option in the long run. Replacing the filters and membranes is equally expensive, but an AMC ensures proper servicing of the machine and replacement by genuine spare parts, RO membranes, and other filters.

The pricing is reasonable, but the maintenance charges or AMC can push the overheads significantly.

7. AO Smith Z8

AO Smith Z8

If you are looking for an RO Water Purifier with a Hot water dispenser, the AO Smith is the best option.

Pros

  • Ability to dispense hot water at varying temperatures
  • Patented side-stream RO membrane to enhance performance and membrane lifespan
  • Silver Charged Membrane Technology to prevent microbial contamination.
  • ZX dual filter for enhanced purification
  • Night Assist feature

Cons

  • Water Wastage
  • The machine occupies more space.
  • Small hot water tank capacity

Water purifier technologies keep improving, with the latest models like AO Smith Z8 offering hot water dispensing facilities for added convenience. This machine can deliver normal and hot water in the 45 to 80 degrees Celsius temperature range. This feature enables the AO Smith Z8 to qualify as one of the best water purifiers in India.

Read More

Performance-wise, the AO Smith Z8 ranks at the top because of its exciting additional purification facilities like ACMT and ZX dual filters. In addition, the side-stream RO membrane is a unique feature where the source water enters the RO membrane from the sides. It improves the water purification process by preventing the accumulation of salts in a single place. Otherwise, the RO purification is the same as in other similarly equipped appliances.

Water wastage is unavoidable, but AO Smith claims its Advanced Recovery Technology saves more water than other RO machines. We have tested it and found it valid to a certain extent. However, water wastage depends on the water source quality. Nevertheless, this claim by AO Smith is better than the marketing gimmick, Zero Water Wastage, by Kent RO.

Other exciting features include the Advance Alert System, where the machine alerts you to replace the filters and RO membrane. Besides, the Auto Cleaning feature is innovative. Installing the machine is simple because of its versatility. But this machine occupies more space than other water purifiers.

AO Smith has a one-year warranty on the product, with the option of continuing with an AMC. However, the maintenance costs of the AO Smith Z8 are high, averaging around Rs 5,000 per month. In addition, the appliance is the most expensive water purifier on this list.

While the AO Smith Z8 is expensive, it delivers excellent performance to qualify as India’s best water purifier under Rs 25,000. While the Z8 is a good machine, AO Smith has introduced an advanced model, Z9, with sensors.

8. V-Guard Zenora

V-Guard Zenora

Quality RO Water Purifier with No fancy features. Suitable for High TDS Water.

Pros

  • Ideal for water with TDS levels up to 2000 ppm
  • Excellent flow rate and adequate water storage
  • 8-stage water purification plus Mineral Balancer feature
  • LED indicators
  • Easy to mount and good faucet arrangement,

Cons

  • High water wastage
  • High maintenance costs
  • It cannot work under low water pressure.

Installing the V-Guard Zenora is simple because you can comfortably mount it on the wall or place it on the counter. Besides, the machine has an exquisite design that matches your kitchen ambiance. Moreover, the flashing LED indicators and the ergonomic faucet arrangement make it look sleek.

Read More

The LED indicators enhance user convenience levels. The flashing blue lights indicate that the purification process is active, whereas the red lights denote a lack of water supply or absence of purification. The 7L storage capacity should be ideal for the average Indian family.

Performance-wise, the 8-stage water purification includes RO and UV, this machine ranks among the best water purifiers in India for Borewell water under Rs 10,000. It can handle TDS levels up to 2000 ppm and purify all types of water.

Depending on the water source quality, this machine can achieve a water purification rate of 15 liters per hour. However, the machine cannot function when the water pressure is lower than 4 psi. Therefore, you need to install an additional water pump that costs extra.

V-Guard Zenora does not have a TDS controller. Instead, it features a novel arrangement, Calcite Mineral Balancer, equivalent to the Mineral Enhancer cartridge used in other machines. It balances the pH levels and replenishes the lost minerals in the RO-purified water to make it taste like Bisleri mineral water.

This water purifier has a unique UV lamp arrangement enclosed in a glass chamber, whereby the RO-purified water does not touch the UV lamp. Thus, it prolongs the lamp’s lifespan. Besides, pre and post-carbon filters remove VOCs and foul odor from water to enhance its taste.

Maintenance costs are expensive because the filters and membranes require regular replacement. Generally, it costs around Rs 4,000.

Vguard Zenora review

The machine has a comprehensive one-year warranty covering all filters, electrical parts, and RO membranes. V-Guard also offers one free re-installation facility, free replacement of two pre-filters, and two pre-emptive maintenance services.

These features make the V-Guard Zenora a favorite, with consumers living in areas with water sources containing more than 400 ppm TDS levels. In addition, its reasonable pricing qualifies the V-Guard Zenora as the best water purifier under 10,000.

9. AO Smith X2 UV Water Purifier

AO Smith X2

Excellent UV Water Purifier that is suitable for Low TDS Water.

Pros

  • Ideal for purifying water with TDS levels of less than 300 ppm
  • Excellent water filtering rate and can work in an extended water pressure range.
  • Compact design with digital display for providing crucial information
  • Good storage capacity of 5 liters
  • Lower maintenance costs and no water wastage

Cons

  • After-sales services are not satisfactory.
  • The tap water taste does not change.

An RO water purifier is not essential, especially when the TDS levels in water are less than 300 ppm. Moreover, many municipal corporations in India undertake to purify water using RO purification plants before distributing it to its residents. Under such circumstances, you do not need an RO water purifier. Instead, a UV water purifier like the AO Smith X2 can work wonders.

Read More

The purification process is simple because it does not have any RO membrane. Instead, it has a pre-filter, a carbon block filter, a UF membrane, and a UV lamp. The pre-filter traps large, suspended particles, whereas the carbon block filter removes VOCs and eliminates foul odor. UV radiation kills bacteria, viruses, and other harmful microorganisms.

Installing the machine is not an issue because AO Smith offers free installation. However, AO Smith has few service centers in India. So instead, they rely on third-party service providers who may charge separately for the installation.

This water purifier occupies sufficient space on the kitchen counter. So We advise you to mount it on the kitchen wall. The AO Smith X2 has a sturdy ABS plastic body that encloses all the machine’s components, including the pre-filter.

The unique water dispenser design allows users to fill regular-sized glasses or bottles. The 5L storage capacity is ideal for small to medium-sized Indian families.

This water purifier delivers good performance, but we advise you to check TDS levels in the source water before purchasing this appliance. Since it can work in an extended pressure range of 5psi to 30psi, this appliance is ideally suited for high-rise buildings. The water purification rate of 30L per hour is excellent, with the 5L tank taking around ten minutes to get filled.

While the tap water taste does not change, this appliance kills pathogens and microorganisms to purify the water and improve its hygienic quality.

AO Smith UV Water Purifier in India

Unlike RO water purifiers, the AO Smith X2 does not require much maintenance. But, on the other hand, the AMC costs around Rs 1,400. Besides, AO Smith offers a one-year warranty on the machine. But the warranty does not cover the filters and the UV lamp.

Models to avoid

Hul Pureit Copper UV Water Purifier: Though the performance levels are the same as any other UV water purifier, it has significant drawbacks. This machine does not have any storage capacity. Therefore, it will not be helpful during power cuts. Secondly, water dispensation takes a lot of time. One must wait 40 seconds to a minute after switching on the machine.

Aquadpure: Please steer clear of this brand, as their water purifier is assembled and the quality of both the body and filters is subpar. The service is also extremely poor
