10 Best Water Purifiers in India for Home (2026)

The 10-stage purification stack ensures that Borewell and tanker water is handled well. Please note that UC Native models are only suitable for high TDS water above 300 ppm. If the TDS water in your water is low there is no need for an RO unless your water source has flouride, arsenic or lead.

Both UC Native models have a convenient tray to hold bottles while filling, but the M2’s touch presets make it easier to fill a measured glass or bottle with a single press.

The difference between them is in dispensing. M1’s tap works without power, which is a big advantage in outage-prone areas. M2’s touch panel needs electricity even for dispensing, so it is best suited to homes with stable power. Apart from this, the filtration performance and storage are identical.

Service quality depends heavily on location. In cities and larger towns, Urban Company’s own technicians handle installations and maintenance. In rural areas, service is passed to third-party providers, which can mean slower response times and variable quality. If your pincode is directly serviced by Urban Company, these models are among the most cost-effective choices in the market.

In our testing, we switched between municipal water at 150 ppm TDS and borewell water above 600 ppm. Adjusting the output-TDS from the app kept the taste consistent in both cases, without needing any hardware changes. This is a clear advantage over fixed-TDS systems, where taste can swing noticeably when the source changes.

The filter-life tracker is reliable and removes the guesswork from maintenance. There is no forced AMC, so you pay only when a filter actually needs replacing. As of now, Atomberg has been including a booster pump at no extra cost for homes with low inlet pressure, making it easier to install in apartments.

Compared to most ROs in this price range, Intellon stands out for its customisation and transparent upkeep. If you have stable service access and want control over taste and TDS, it is one of the most practical choices in the market today.

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 was 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 is exhausted.

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, this HUL Pureit Eco Water Saver RO water purifier is one of the best for under Rs 15,000.  

We advise checking TDS levels in the source water before finalizing your water purifier because TDS levels below 350 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.

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.

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.

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.

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.

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, We 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.

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.

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.

While Livpure does not offer the best after-sales services, especially for installation, the company offers a decent warranty and AMC facilities.

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.

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. 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.

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.

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.

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.

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.

Performance-wise, the AO Smith Z9 Pro ranks at the top because of its exciting additional purification facilities like SCMT and ART Max 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 Z9 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 Z9 Pro is expensive, it delivers excellent performance to qualify as India’s best water purifier under Rs 25,000.

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.

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.
