Best Water Purifier of 2021

In this article I will show you Best Water Purifier of 2021 on Amazon You can easily Buying this list of purifier.

We bought a TDS meter to our home last week. It costs less than about Rs. 300, and proved very useful. When we tested the water we could see that the TDS reading of our home water supply is in the range of 800-900. 

Well, to someone living in Bangalore this shouldn’t come as a surprise. We know it’s rough on our skin.

And that’s why a Best water purifier with RO (reverse osmosis) is a must-have for residents of metro cities where you get borewell water and other areas with TDS greater than 500 ppm.

We bought our water purifier Eureka Forbes AquaGuard Enhance RO some 6 years ago. It was a wise decision to buy. The annual maintenance with filter changes cost us about Rs. 4000 + annually, but the quality of the water is quite good. So is after-sales service, which makes it a good choice overall.

There are numerous other options on the market too to confuse any one. That’s why we’re bringing you this short list of India’s best water purifiers.

Best Water Purifier in India

Before we get to the detailed list, let’s understand the terms commonly used when reading about water purifiers.

RO meaning Reverse Osmosis is a process in which water passes through a highly porous layer in the opposite direction of natural osmosis with an applied pressure to remove impurities within it. The process helps remove TDS, lead , mercury, calcium , iron, asbestos and is a mechanical barrier to biological contaminants, such as protozoan cyst, bacteria, and virus.

UF means ultra-filtration in which small particles hanging in water are trapped in the membrane. It helps eliminate particulate matter and the macro molecules.

UV stands for Ultra Violet rays that destroy in water germs and microbes.

TDS is Total Dissolved Solids composed of inorganic salts, in particular sodium , potassium , calcium, magnesium, etc. TDS levels of less than 300 mg per litre are considered suitable for drinking water according to WHO. Ideally though, filtered water from RO should have TDS less than 100 ppm.

Let us now take a look at the list. In this list, almost all water purifiers cost more than 10000 rs. So if you are looking for a budget-friendly alternative, check our list of best water purifiers under Rs 10000.

kent best water purifier

Ideal for borewell and brackish water receiving areas with TDS rates between 500-2500, Kent New Grand is one of India’s top-rated RO water purifiers.

It eliminates inorganic pollutants, odors, pollutants, bacteria , viruses and other contaminants with 7-stage water purification including reverse osmosis, ultrafiltration, UV filtration and TDS controller, but still maintains natural minerals in the water. Sediment, carbon block filter, UF, and post carbon are among the filter cartridges. Though the filtration system is advanced, the Save Water technology minimizes water wastage.

The purified water is stored in an 8 liter transparent tank made of plastic made from food grade. Thanks to the UV disinfection feature in the tank, you can store the water in the tank for an extended period of time, without worrying about contamination. Note that while the Kent New Grand has 20 liters of water purification capacity per hour, it should ideally be used to purify just about 100 liters of water a day.

Another benefit of this water purifier is the computer-controlled operation, which indicates when it is time to change filters and when to adjust the UV lamp.

Thinking about the drawbacks, you’ll need to fork out about Rs. 4500 plus for a full filter change, which usually takes place every 12 months. (If you want to extend the life of the filter, you could install a pre-filter that purifies impurities such as sand costing around Rs. 1000.) Also, in some towns, you might find the after-sales service not so prompt.

Water wastage for every litre is a bit too high at 500 ml. However, along with the water purifier, you get a tank, which can be used for gardening, mopping or other purposes to store the refuse water.

Although there are a few flaws, the Kent New Grand overall has a one-year manufacturer warranty and 3-year free service and an excellent filtration system in place

Is one of the best decisions to make. Now, if you’d be happy with a lower purification capacity of 15 liters per hour and 75 liters per day, then with a slightly lower price tag, you could opt for Kent Grand.



Eureka Best water Purifier

Black, trendy and futuristic, this water purifier from Eureka Forbes’ house has been dubbed an intelligent water purifier. Its purification system with UF, UV chamber, iFilter, ChemiBlock, Biotron, Mineral guard and taste enhancer is almost identical to the previous Aquaguard Enhance RO. But its user-friendly features are what makes it truly smart.

The stylish water purifier comes with LED indicators to alert you when water is full, pressure is low, water supply is not available, or error occurs. The filter cartridges last for one year or up to 6000 litres. And the device also features smart plus which protects the device against voltage fluctuations.


However, a drawback is that it has only a 6-liter storage tank compared to the 7-liter tank of the Aquaguard Enhance.

So if you fancy a smart advanced water purifier then the Eureka Forbes Aquasure is sure to delight you.



ao smith best water Purifier

If you fancy a water purifier that will offer you hot water, then maybe this AO Smith Z8 is the only choice in India that will satisfy your needs. It also has the largest 10 liter tank in the segment.

The AO Smith Z10 removes up to 95 per cent of TDS in water with 8 stage advanced filtration system. The heating element helps you with 45 to 80 degree Celsius hot water which, apart from drinking, can be used for soaking pulses and cereals, helping you to speed up cooking and sooth sore throat etc. Don’t worry, there’s a child lock in the hot water faucet to prevent any untoward accidents.

Note that they don’t boil the water. So, it is not advisable to use this water without further boiling to prepare baby food or bottle sterilization.

The 8-stage filtration system includes a pre-filter, sediment filter, carbon block, RO, mineralizer, dual-filter double safety, and advanced recovery technique.

It is said that the ART (Advanced Recovery Technology) is a unique technology that reduces water wastage without compromising the quality of purified water.

Thinking about the drawbacks, first of all, to get hot water the tank must be completely full. Next, to keep 1 liter bottles, the height between the faucet and the stand is not sufficient. So maybe you need to remove the stand for ease of use. Yet another frequently seen complaint is that the installation isn’t so prompt and technicians sometimes lack product expertise.

The AO Z8 is indeed an alluring choice with an annual maintenance cost of about Rs. 4500, pretty “hot” features and a large tank. It comes with a hefty price tag, though, which makes you think twice before you buy.



Havells max pro best water purifier

Havells is a name you trust when it comes to home appliances. They have recently forayed into the segment of water purifiers, and have gained rave reviews.

Their Max RO water purifier that was launched in 2018 is one of their best suited models if your home’s water supply is less than 2000 ppm.

Water moves through several filtration layers in this purifier, for better performance. First, sand and other heavier particulate matter are collected via sediment filter, followed by activated filter cartridge. Then, it passes through RO membrane, followed by UV to eliminate pesticides, harmful chemicals, and water impurities.

In addition to this, water is passed through a mineral cartridge and then a silver impregnated taste enhancer to correct the pH and improve the mineral content. The last cartridge of revitalizers is said to help improve hydration and the absorption of minerals.

Havells has also introduced “I Protect” technology built into the water purifier to monitor the quality of the water. The Havells Max RO also has warnings for self-diagnosis, purification process, tank full, low pressure and error alarms for UV, SV and pump failure, as with Kent Grand Plus.

The purifier has an hourly output of 15 litres. The 7 liter removable storage tank is also easy to clean. Also, the water purifier has a holder on which to keep cups and small bottles for water filling.

The filter cartridges usually have to be changed annually when discussing maintenance. The annual maintenance costs of Rs. 4-4.5k including filter change.



blue star best water purifier

In terms of air conditioners, Blue Star is quite a reputed brand. Their entry into the segment of the water purifier was also well received.

A tad less than most entries in this list cost the Aristo water purifier. But unlike them, Blue Star Aristo only has 6 stage purification of the water. Pre-filter to eliminate larger particles such as sand, pre-carbon filter to remove dissolved contaminants and impurities, sediment filter, RO membrane, UV lamp to destroy bacteria, and Aqua Taste booster post-carbon filter.

What it lacks is ultra-filtration compared to Kent New Grand, and the silver taste enhancer compared to Havells. If you’re adamant about getting an ultra-filtration device, you may need to settle for a slightly higher price tag for Blue Star Aristo RO+UV+UF AR5BLAM01.

When you look at it critically, Blue Star Aristo’s filtration device is in no way inefficient than any of the other water purifiers on this list. To improve filtration efficiency Blue Star uses a double layered RO membrane + UV lamp.

The activated carbon filter impregnated from copper adds to the filter’s antibacterial property. In addition, according to Ayurveda, water with traces of copper is said to be very beneficial for health.

An added advantage of this water purifier is that it comes with an extra pre-filter that improves the life of in-built filters, as mentioned earlier.

Blue Star Aristo storage tank has a capacity of 7 litres.

The water purifier ‘s warning device shows when the purification is on, the tank is full, the pressure is low or the UV lamp fails. If you have little children and the purifier is mounted beyond their control, the child lock feature is also very useful.

One of this water purifier ‘s key drawbacks is that after-sales support and installation isn’t very timely.

With a 1 year warranty and an efficient filtration system, the Blue Star Aristo is one of the best choices for homes with a TDS level of less than 2000 ppm for water supply.
