Best Water Purifier – Buying Guide

What is the indicator of life on any planet?

When we say, we are exploring possibilities of life on Mars, what is it that astronomers and scientists are searching for? The answer to both the questions is ‘Water’.

Yes, water is as essential to life as air. One cannot imagine any life form without water. Fortunately, our Earth is blessed with sufficient water to take care of life in the present as well as future generations.

Sources of water pollution

The rivers are pristine when they descend from the melting snowcaps. As they find their way to the plains, these rivers gather salts and minerals from the rocks and sand.

These salts comprise of potassium, sodium, chlorine, and magnesium along with the phosphates and the nitrates. They form the major component of the totally dissolved solids (hereinafter referred to as TDS).

You will be hearing about TDS more as we go deep into this buying guide.

In addition to the natural salts, we have humans pitching in with their contributions towards polluting this pure river water.

You have human wastes like sewage and other impurities flowing into this water. Industries contribute their mite by releasing harmful industrial chemicals such as arsenic, lead, iron, and mercury.

All these impurities find their way into the human settlements thereby causing water-borne diseases like cholera, dysentery, etc. Therefore, there is an urgent need to purify the water resources before consuming them.

This is the concept behind the functioning of the various water purifiers. You have different methods of purification based on the level of impurities and TDS in water. We shall discuss each type of filter for the benefit of all.

Types of impurities in drinking water

As discussed earlier, you have various kinds of natural salts finding their way into your kitchen through the water resources. Similarly, groundwater also contains a lot of minerals and salts in its natural form.

As you move towards the coastal areas, the proportion of salt increases in the groundwater. Now, bore well and dug wells are the primary sources of water in such areas that do not have the rivers to bank upon.

This well water needs purification because it can contain other impurities like suspended plant and animal matter in addition to the TDS.

There are municipalities in towns and cities that treat such water resources with disinfectants like chlorine. Hence, you find a higher proportion of chlorine in areas served by municipalities. This is also harmful to your health.

Your water purifier needs to take care of these impurities as well. The rivers and other water resources have to contend with human, animal, and industrial wastes.

Eliminating these wastes requires the use of modern technology like Reverse Osmosis (RO), Ultraviolet purification (UV), and Ultra-filtration methods (UF). The modern water purifiers employ any or all of these methods of purification.

The acceptable TDS levels

We have seen the concept of TDS in water. We know how it manages to find its way into the water resources. In a way, our body needs some of these minerals and salts for its healthy growth.

Hence, one should ensure not to eliminate them completely from the drinking water. Now, the question arises as to what the acceptable TDS levels are.

The normal acceptable TDS levels are as follows.

  • Below 300 – Considered to be excellent
  • In the range 300 to 600 – Good for human consumption
  • Above 600 but below 900 – Fair and acceptable
  • Between 900 and 1200 – Poor levels of TDS
  • Above 1200 – Unacceptable and unfit for drinking purposes

Note that these levels are purely indicative. In the normal course, you will find ground level as well as other water sources having TDS levels below 900.

As per the above table, it should be fair for consumption directly. Is it true? Unfortunately, the answer is NO. The level of concentration of individual elements of TDS is more important than the general TDS value.

It can happen that you might have water with TDS levels in the range of 300. But, the water can have a high concentration of arsenic or mercury and a lower concentration of other salts.

Under such circumstances, is the water safe? You have the answer at the tip of your tongue. This water is certainly not palatable. Hence, you need water purifiers to eliminate these impurities completely.

Water purification technology explained in brief

The sediment filter

This is an optional arrangement. Usually, you have this filter fitted outside the machine. This filter takes care of the visible suspended particles and larger impurities. This filter enhances the life of the RO membrane as it eliminates the larger particles and does not allow them to enter the machine.

You need not use this sediment filter when the input source of water is clear, especially the water treated by the municipalities before distribution to the households.

Pre-activated carbon filters

The pre-activated carbon filter removes organic and the other volatile compounds from the water that usually give the water its bad odour.

Reverse Osmosis mechanism
Working of Kent RO

The next stage of filtration is RO filtration. In the normal course, the water does not have a tendency to move from a higher concentration to lower concentration when passing through a semipermeable membrane.

Hence, you need to use a pump to push the water through the RO membrane. This is the principle of reverse osmosis.

The RO membrane removes all kinds of impurities in the water such as TDS, pesticide residue, heavy metal impurities like mercury, lead, arsenic, and biological impurities like bacteria, viruses, and microorganisms.

This water is separated into two parts, the impure part that goes down the drain and the pure and filtered water that passes through the UV chamber for the next stage of filtration.

Ultraviolet protection

The pure water obtained through RO filtration contains traces of bacteria and viruses. This is because the RO membrane cannot filter out impurities with molecular weight less than 20. It cannot eliminate monovalent ions like sodium, etc.

Hence, this water now passes through the UV chamber where the ultraviolet radiation kills all microorganisms and bacteria thereby making the water 100% safe to drink.


The resultant water now passes through an Ultrafiltration membrane to remove traces of residual impurities. This filtration membrane contains minute pores that trap any impurities that might have escaped elimination in the RO process.

The Post-activated Carbon filter

This filter is responsible for removing the volatile organic compounds that cause the bad odour of the pure water flowing out of the RO water purifier. This improves the taste of water.

The TDS Controller

The water that comes out of the RO water purifier is pure and healthy. But, the RO mechanism eliminates almost all the TDS from the water. In fact, it removes more than 90% of TDS from the input source. This includes good and healthy salts like calcium and magnesium, etc. These salts and minerals are necessary for the overall growth of the body.

The TDS controller solves this issue by separating the input water into two parts, A and B. Part A goes through the RO membrane whereas Part B passes through the UV / UF membrane that does not remove the TDS but kills the microorganisms.

The TDS controller then selectively mixes this water with the RO purified water thereby increasing the TDS levels and increasing the pH value of the water.

Also, Read

The Mineralizer

The disadvantage of the TDS controller is that it releases a part of the input water into the RO purified water thereby providing an opportunity for contaminating the RO purified water.

The mineralizer releases the appropriate minerals lost during the RO purification process alone. This replenishes the mineral content of the water and thus improves the quality of output water.

Factors to consider while buying water purifiers

You should always conduct the test of the water source at your house before deciding the type of water purifier to opt for.

1. Do the TDS evaluation test to determine the amount of TDS in water.

2. If you live in an area inhabited by industries, it is better to conduct a chemical test of the water source to determine the level of industrial pollutants.

3. If in doubt, you can always go for the best, i.e. the RO + UV + UF water filters. However, remember these filters are comparatively expensive as compared to the other water filters.

4. Your budget plays a very big role in deciding the kind of water purifier you choose. While determining the budget, you should also factor the cost of maintenance and replacement of filters.

Best Water Purifier - Frequently Asked Questions

1. Which water purifier brand offers the best after-sales services?

On this era of customer service, all water purifier brands offer good after-sales services.

However, it depends on various factors such as availability of service centres in your city, accessibility to spare parts, and so on. The best way to verify these factors is to do a local search on Google or go through Just Dial reviews.

Going through the official websites or e-commerce websites where customers post their reviews is also a good way of ascertaining the after-sales service facilities of water purifier brands.

2. What is the annual maintenance cost (AMC) for an RO water purifier?

Most of the top water purifier brands offer regular AMC services. The rates depend on various factors. Usually, it is in the range of around Rs 4,000 per annum. However, it is better to verify from the water purifier AMC provider.

This AMC includes the cost of replacement of the various filters like RO membrane, UV and UF filters, activated carbon filters, and sediment filters.

You have to replace these filters on an annual basis to extract optimum performance from your water purifier. Refer to the actual specifications

3. What are TDS Controllers / Modulators?

As the name suggests, TDS controllers control the proportion of TDS in the water coming out of the RO water purifier. Why do you need these controllers?

The RO purifiers reduce the hardness of input water by approximately 90%. Hence, if the TDS level of the water source is around 800, the TDS proportion of the output water will be in the range of 80.

This water with a low TDS level does not have good taste. Secondly, you need some minerals and salts in the water to enhance the taste. The TDS controllers work in the following manner.

The TDS controller divides the water that goes into the RO water system into two parts. One part goes through the RO membrane whereas the other part goes into the UV and UF filters.

The water that goes through the UV and UF filters do not undergo any change in the TDS levels. Therefore you get two different outputs. The final output is a mixture of both these waters. This is the job of the TDS modulator.

4. What is Mineralizer / Mineral guard

One must admit that the RO water purifier does a great job of purifying the water. But, it removes essential minerals along with the hazardous ones.

This leaves the output water with a bland taste that does not have much nutrient value. Therefore, you have water purifier brands including an extra stage of filtration that ensures the addition of essential minerals to the water.

This helps in maintaining the pH balance as well. Different brands have different names for these mineralizers. Aquaguard names it ‘Mineral Guard’.

5. How much water is wasted with RO water purifier?

The biggest drawback of RO water purifiers is that it wastes water a lot. For every litre of pure water it produces, the machines waste 2 litres of water.

The wastage of water depends on the quality of the input water. The higher the TDS of input water, the higher is the wastage

6. How do you use reject water?

The reject water contains 95 to 99% of impurities. Hence, this water is absolutely unfit for human consumption. However, there are other uses.

You can use this water for gardening, cleaning utensils, mopping floors, cleaning bathroom floors and toilets. However, one should note to wash the utensils with tap water to remove the salt deposits.

7. ABS Plastic or Stainless Steel tank – Which is better?

Storage tanks are essential ingredients in any water purifier. These storage tanks are anywhere in the capacity of 10 litres or more.

Hence, you need strong material to withstand the weight of the machine as well as the water. ABS (Acrylonitrile Butadiene Styrene) is a thermoplastic polymer capable of withstanding high-temperature fluctuations.

It is a recyclable material much unlike the thermoset plastics. They are non-toxic in nature. This makes this material perfect for manufacturing water storage tanks.

Steel is comparatively heavier to ABS plastic. Secondly, ABS plastic is non-toxic and more durable than steel. They can withstand a high-temperature range.

ABS plastic does not require as much maintenance as required by steel tanks. Hence, they are preferable to stainless steel tanks today.

8. Is it safe to buy water purifier online?

It depends on the customer and the website from where he chooses to purchase. Some people are more comfortable buying water purifiers after having a look at the features. Some people are comfortable buying online.

However, one should go for reputed brands from reliable websites like Amazon. You get good deals at these websites.

9. Can I buy a non-branded RO water purifier?

It is never advisable to buy a non-branded water purifier. Your health is always more important. Invest in a reputed brand because of the quality you get.

Non-branded water purifiers do not have TDS controllers or mineralizers. This affects the quality of the output. These locally made water purifiers might be inexpensive, but they are not worth investing. You will lose all the minerals in the water when you opt to buy the cheap ones.

Final Words – Wrapping it up

You have just gone through the RO water purifier buying guide. This guide should help you make an easy decision about opting for the best water purifier.

We have seen the differences between the various purification technologies and seen that a combination of all these technologies is the best option available to you.

No need to use an Alkaline water purifier or RO water purifier as the TDS levels in your water source is very good.


Please read this post to know know complete details about the Alkaline water.

The TDS in your water source is perfect. Just an UV UF water is enough to remove any bacterium and dust present in the water. Please have a look at the below models

Want to know about Alkaline water purifier. Which is one should buy RO or Alkaline. Please provide better option with Alkaline water purifier


Sir, I am from Gunter, Andhra Pradesh. We are drinking tap water which is coming from terrace tank being filled up from muncipal water pipe line by pump, It’s tds may be around 400ml/l . To remove any bacteriand virous. , what type of water purifier is to be used.? Ro purifier or UV purifier or UF purifier or a purifier that consist of all these three . Please give necessary clarifiy. Thanking you, in anticipation.

Kitchenarena Team

RO water purifier with UV UF combination is required to remove excess TDS from the water. IF the TDS is above 400ppm, you have to install an RO water purifier otherwise UV + UF water purifier is enough to remove the bacteria and other contaminants from the water.


I am from HYDERABAD.
Could you plzmlet me.know water purifier with hot water dispense and maintenance cost.
My source of water is manjeera and TDS will be around 300ppm.

Plz provide good water purifier with good customer service…..and also detailed filters with maintenance cost..

Kitchenarena Team

Manjeera water is good and the TDS levels in your water source is perfect. There is no need to buy an RO water purifier. Just an UV water purifier is enough to remove any bacterium that is present in the water.

Please have a look at AO Smith UV water purifier with Hot water dispenser

A.O.Smith Z1 UV (Amazon Link – https://amzn.to/3eHO0y0)

The maintenance cost is around Rs.2000 per year which is a lot less than RO water purifier maintenance.


I am from Hyderabad and bought the top of the line UV cum water purifier on 20th March and was promised that it will be installed the very next day. The idea behind it was we all in india were expecting the lock down and as I have a 85 year old fragile mother, I didnt want to buy water from outside vendors.
Post the purchase, Shiva and Venkat would avoid my wife’s and my calls and we somehow got in touch with them and on their request we got a plumber who installed it online over video call with Venkat. It was not installed well and he promised that he will find a solution next day. He then disappeared again and when I escalated it to Ram Prasad, he put me on to another person Ravikant who again put me on to yet another person Ramakrishna. Ramakrishna mentioned that we “should not” drink the water till we check the TDS levels and that he will come the next day to check. Even this promise was broken and when i escalated this to Ram Prasad and REQESTED him to help us as WE WERE HAVING A MAJOR WATER he was most casual and disrespectful. I strongly do not recommend anyone to associate with such people who dont know the definition of “Customer Satisfaction”. I am scrapping the product and am telling all my friend’s and acquaintances about the experience. God save the company who has such people in the system.


Hi.. My source of water is DJB, so TDS is not an issue but since we store water in overhead tanks, which are cleaned only once in a year, the organic impurities are a concern. Which RO should I go for.


Kitchenarena Team

If TDS is not the issue, there is no need to buy an RO water purifier. You can simply buy a water purifier with UV UF combination that eliminates all the bacterium and cysts from the water.

Hi Kitchen Arena team – I am confused with whether to go for a TDS controller or a Minaralizer based system.

Can you please recommend a couple of options for both?

Kitchenarena Team

Hi Rajeev, You can opt for a water purifier with TDS Controller if your water source is not that polluted. Some mixing of source water will be done to the final purified water to maintain the TDS levels in the water. On the other hand, an RO water purifier with Mineralizer completely removes the TDS from the water and adds minerals at the end of purification process. Please read this post to know more (https://www.kitchenarena.in/tds-controller-vs-mineralizer/)

I stay in Paradip,where tds is 2000.Which type of purifier is suitable for me.

Kitchenarena Team

Hi Bipin, 2000 TDS is very high, You have to buy an RO water purifier.

Please have a look at the below models

I stay in Bangalore city (multiple dwelling unit society).The water is sourced from borewell, water tanker etc; TDS levels are nearly 450 (upon randomly checks) and i am looking for water filter which will guarantee best purification and 150 TDS levels (as per WHO recommendation). Presently i have Aquasure, which give 25 TDS post purification and i am looking for a filter which will give good water ( and not dead water), please advise.


As per WHO recommended TDS level should be upto 150 post RO and all filtration process, which among all these filters guarantee 150 TDS ?


Can you recommend us water purifier with technology ‘RO, UV/UF, MTDS ‘ don’t need to install, not needed tap connection, not need to mount on wall.


Hi, I live in Delhi and use Borewell water with TDS 1200. We are a family of 4. Which branded ro is best and budget friendly.

Subhankar Nayak

Between LG ww182ep(ro+uv+uf) and Aquaguard geneus plus(ro+uv+uf) which one will be better to buy ?Maintenance cost is also a factor (lesser is better). Thanks

Kitchenarena Team

Maintenance cost depends on your water quality. Purification wise, both the water purifiers you have mentioned are good and process is almost same. Please inquire about the service quality with local customer care and opt for the brand that provides good support.

Subhankar Nayak

Thanks for your prompt reply.I have one more question , LG ww182ep model has stainless steel tank , is it better than the regular food grade plastic tank or is it a gimmick and is there any disadvantages of the steel tank ?(Like toxic or such)


Hi I m living in an area where water TDS is around 1500 TDS. Which water purifier system should I go with? I am looking for something with low maintenance. Thanks

Kitchenarena Team

TDS 1500 is very high, you have to buy an RO UV water purifier that comes TDS Controller or Mineralizer. The Maintenance cost will be around Rs. 4000 per year for most of the RO water purifier. You can also opt for an AMC. Also, the filter life depends on the quality of the input water which in your case is bad. So, it is better to go with AMC. You can have a look at the below models

Kent New Grand 8L RO (Amazon Link – https://amzn.to/2CtCvt1)

Shobhita Agrawal

TDS level of my home water is 600 and source is borewell water mixed with municipal water.
Please let me know which technology purifier should be bought NF or RO?
And please also suggest good brand for the recommended Technology.

Kitchenarena Team

The TDS levels in your water source are sightly above the recommended level. You can opt for an RO + UV water purifier that comes with a TDS Controller. Kent Grand Plus, Pureit Ultima, AO Smith RO, Hindware and good. You can have a look at the models mentioned in the above article.

Bhagwan Murthy

I have very clean bore water with TDS 507. I am using it directly for cooking. I want to pass it through RO and VF for drinking. Instead of using the overhead tank as source, which gets easily contaminated with dust. cobwebs and moss, I will use a separate 10 litre tank as source into which I will pump the bore water periodically. Can this tank be kept below the filter instead of above?

Kitchenarena Team

If the 10-litre water tank can provide enough pressure to pump the water into the water purifier, you can place it below the water purifier. As you will be using an RO water purifier with UV/UF combination, there is no need to install a sperate tank, you can just use the overhead tank as a Reverse Osmosis membrane is completely capable of removing all kinds of contaminants from the water.


Can i go for Kent Grand Star? Please review it…

Kitchenarena Team

Kent Grand star comes with RO UV UF purification process. Also, there is a TDS controller to retain the natural minerals in the water. The 9-litre storage tank comes with UV disinfection protection. Also, there is a digital display that allows you to monitor the status of the tank, filter life, and water quality.

The purification process is the same as Kent grand plus but this model comes with a Digital display and the 9-litre storage tank that is suitable for large family also.


Thanks for prompt reply

If I do AMC for pureit will it not cover all expenses ?

In TDS modulator of Kent a part of the water actually bypasses the RO membrane some potentially harmful dissolves salts may be left behind

Whereas in Pureit all the water passes through the RO then fortified from mineral cartridge!!!!!

Please opine

Kitchenarena Team

You can opt for AMC, it will cover all the expenses.

Unless you are living in a very polluted area or near to a factory, there won’t be harmful TDS in the water. If you are not sure, you can go with Pureit Ultima or LG water purifiers that offers 100% RO purification.


My water supply is bore well

TDS around 700-900

A bit confused what to choose TDS controller of Kent Grand plus or mineraliser of Pureit Ultima

Kindly advise

Kitchenarena Team

Kent Grand Plus is the better product, Pureit Ultima maintenance cost is very high.


How about AO Smith Z8 ?

TDS 800 is found in my borewell water.


Iam a resident of telangana, my water source is municipal water, tds around 250-280 which water purifier should i buy?
How is 3m water purifier? MODEL- IAS140S,RO-R8 CW.
Is UV/UF water purifier enough for me or should i go for a RO purifier?
And what do suggest for whole house filtration systems??
Kindly give your advice.

Kitchenarena Team

3M whole house filtration system foes not require any electricity and removes impurities like dirt, mud and other suspended impurities that are larger than 5 microns.

Normal UF water purifiers (UltraFiltration) comes with a pore size of 0.1 microns and are capable of removing bacterium and cysts from the water which is not possible with 3M filtration.

The TDS levels in your water source are below 300ppm and good. So, there is no need to for a Reverse Osmosis water purifier. You can simply install a UV/UF water purifier like Kent Maxx, Havells UV Plus or Aquaguard superb UV Uf water purifier.



I am a resident of himachal pradesh, interested in buying a water purifier but getting confused after reading lots of articles on same.
our water source is river water that comes from the glaciers. The TDS level is 24 mg/liter. For this i am sure i should not go with the RO system. But for UV+UF please suggest me a good brand in terms of service and reliability. Havells UV plus or Kent Maxx? Or any other brand/model as per your experience?


Kitchenarena Team

The TDS levels in your water source are good and there is no need for an Reverse Osmosis water purifier. Both the models you have mentioned are the best selling UV UF water purifier models in India and the purification process is almost same. Contact customer service of both the brands and opt for the one that provides quick support at your place. Also, the AMC for UV UF models will be around 1500 per year and not much maintenance is required.


Thank you so much for replying and clearing my doubt.


Im living in chennai. I use borewater which is yellow water (high iron content).
Currently I do two levels of Filteration:

Level 1: Iron remover plant (MORF India). Output Water TDS – 912. AMC-Rs.3000/yr
Level 2: Water Purifier (Aquaguard – RO Only). Output Water TDS – 115. AMC-Rs.4500/yr

I Prefer to change Level 2 Water Purifier. Reason – Current Purifier is 12 years Old. But still runs good.

Do I need RO + UV + UF OR just RO is enough?
But certainly I would like to add minerals at the end of the cleaning proces.
Kindly recommend a suitable water purifier for my case.
Note: Still I would have Level 1 Plant.

Kitchenarena Team

Hi There, Some of the RO models come with UV/UF to ensure the water is 99% free from contaminants. Also, TDS Controllers are used to retaining the natural minerals in the water. In Some RO models, 100% water passes through the RO membrane and minerals were added at the end of the purification process. Such models were recommended if the water source is very bad. Otherwise, RO models with TDS COntrollers are also good. Have a look at the below models.

Please read this post to know the difference between TDS Controller and Mineral booster (https://www.kitchenarena.in/tds-controller-vs-mineralizer/)


The ground water in khagaria bihar is highly Iron concentrated….. wich type of water purifier should I use.

Kitchenarena Team

What is the level of the TDS in your water source? If it is more than 2000ppm, domestic water purifiers are of no use.

Anything less than 2000ppm, you can use an RO water purifier. To remove iron impurities from the water, you definitely need to install an RO water purifier. Reverse Osmosis is capable of removing Salts and Hard metals from the water.

To find the TDS levels in the water, you can use a TDS meter or you can take the water sample to the nearest lab.

Also, most of the Reverse Osmosis water purifier comes with UV/UF combination to ensure the water is 100% free from contaminants.

Some of the RO models come with TDS Controllers and some models have Mineralizer.

In your case, it is better to opt for a 100% RO water purifier with Mineralizer where 100% water flows through the Reverse Osmosis chamber.

RO models with TDS Controllers allow some water directly into UV/UF chambers.

As your water has a high concentration of Iron, it is better to go with 100% RO models. There are many such models available from top brands.


I want to buy water purifier but i little bit confused which one i should go. There are some technology like RO, UV, UF. Please suggest me which one is best.

Kitchenarena Team

What are the TDS levels in your water? What is your water supply source? If you get water from borewell or multiple sources, you can install an RO water purifier. Most of the ro water purifiers come with the combination of uv/uf for providing additional safety.


How is the other Livpure Glo Lite7 litres RO+UF without mineraliser ?

Kitchenarena Team

That model comes with a TDS Controller to retain the natural minerals. Both methods are good. Normally RO is enough to remove all the contaminants from the water. UV/UF are used for extra safety. Livpure Glo lite comes with RO + UF combination. If Livpure provides good service at your place, you can go with that model.


Is there any difference between kent grand star and kent grand wrt performance?

Kitchenarena Team

Performance and purification wise, there is no difference. But, the Kent Grand Star comes with a -built UV disinfection in the storage tank so you can store the water for a long time in the 9-litre storage tank. Also, there is a Digital display which allows you to monitor the status of the tank, filter life and water quality.

But, the output water quality for both the water purifiers is same.



Please suggest the best water purifier for me,

We are getting water from multiple sources sometime municipal, tank and borewell and TDS like 200-250, 400-500 and 800-900 respectively.

I am confused between two technologies one use by Kent (RO+VU+UF+TDS) and other use by aquaguard (RO+ UV + MTDS) with mineral guard and active cooper etc.

I have short listed few model, Kent Grand * , Kent Grand Plus, Kent Prime, Aquaguard Reviva Nxt( RO+UV+MTDS) andDr. Aquaguard Magna Nxt HD(RO+UV+MTDS).

At present, I am using Aquagaud RO Reviva from last 12 years.


Kitchenarena Team

If you are getting water from multiple sources and the TDS range is above 300ppm, you have to opt for an RO water purifier.

In general RO (Reverse Osmosis) is enough to remove all the hard metals, bacterium and other contaminants from the water. But, some RO water purifier comes with TDS Controllers for retaining natural minerals in the water and other models use Mineral Cartridges to add natural minerals at the end of the purification process.

Please have a look the below articles to know the full difference


Go for the brand that provides quick support at your place. The AMC for an RO water purifier will be around Rs.4000


Thank Shiva,

One more query, does mineralizer/mineral cartridge add mineral or retain mineral naturally available in water? Or add from artificial resource.

Kitchenarena Team

Mineralizer adds natural minerals at the end of the purification process. It does not retain the natural minerals that are already present in the water. TDS Controller retains natural minerals. Please read this post to know the full difference



Thanks shiva,

Which one you recommend, for eureka and kent service good in my area. And I am already using eureka from last 10 years


Which do purifier wastes the least water? People say it’s Kent supreme but generally the reviews are not good for Kent supreme.

Kitchenarena Team

Kent Supreme and AO Smith Z8 are some of the best selling RO water purifiers with less water wastage. The service quality provided by these brands might differ from one place to other.

Also, Please have a look at the below post



Hi .. very useful blog. I live in Bangalore, where we get multiple source water (mixed). I am not convinced with Kent or other major brands who advertise much but service delivery is poor.

What is your opinion about BRITA water purifiers? They are slightly expensive, and are not into major advertising yet, but their product specs look impressive – RO + UF + UV filtration, Alkatron technology to infuse lost minerals, stainless steel storage container, good service promise (call back in 1 hour, issue resolution in 1 day) etc. Also in their AMC they promise even the RO filter replacement.

Any thoughts would be welcome.


Kitchenarena Team

The Purification process is almost same in Brita or any other major RO water purifier brand. These water purifier brands use different | Attractive technology names for the simple purification process. At the end of the day, RO purification process is all the same. Some brand use TDS Controllers and some use Mineralizers for retaining the natural minerals that are lost during the RO purification process.






Kitchenarena Team

Please take the water sample to the nearest lab to find mineral content in the water.


Our TDS is under 200. Do I still need RO or UV should do? What brand would you recommend

Kitchenarena Team

TDS 200ppm is good. RO is not required. Simply install a UV/UF water purifier like Kent Maxx.


My borewell water TDS is above 1200, we 4 members in my family. Could you please suggest best water purifier. And what is the cycle period for service or membrane change

Kitchenarena Team

The TDS levels in your water Are very high, you have to opt for an RO water purifier that removes the TDS from hard water. Filter change depends on water quality and usage. In general, you have to change the filters once in a year and the annual maintenance cost for an RO water purifier will be around Rs. 4000. You can have a look at the below models.

Havells Max (Amazon Link – https://amzn.to/2CmHrQx)
Blue Star Aristo (Amazon Link – https://amzn.to/2ClTD4f)

My choice was

1. AO Smith

2. Havells

Pl suggest if any thing is better and good customer services at Visakhapatnam.

Kitchenarena Team

If you want an RO water purifier with hot water dispenser option, you can opt for AO Z8 RO water purifier (Amazon Link – https://amzn.to/2LLQkq7) Havells Max RO UV is one of the best selling RO water purifiers and is suitable for a medium family (Amazon link – https://amzn.to/2AsZYZA). The customer support offered by these brands might vary from one place to the other even within the same city. So, please inquire about the service quality with your neighbours.


Hi Chaitanya,

I need ur advice on selection of water purifier for my house. I checked near by shops and each of them were suggesting Kent prime plus, Aqua guard Superb/geneus and LG RO=UF model.

My TDS when i checked was around 400 in bore water. Could you suggest which one to choose and about the AMC which one is best??

Kitchenarena Team

No Matter what brand you purchase, the AMC for almost all the RO water purifiers will be around Rs.3000 to Rs.4000

The models mentioned by those shopkeepers are good. You can opt for the brand that provides quick service at your place.


Hello Chaitanya,

Very informative blog. Need your suggestion on choosing a Water Purifier. I’m from Bangalore and I’ve mixed water source with TDS level of around 500-600.

Which purifier would best suit me, budget not an issue.

Thanks in advance.


What is the meaning of AMC? Explain.



Meaning of AMC stands Annual Maintenance contract which used take original manufacture or authorized service dealers or any service experts. I suggest When your machine cross warranty periods than you can go for AMC. Its need to be decided based on your area quality of water, power system controls, based on your maintenance knowledge etc.,

Which is the suitable water purifier where water supply is short say 1 hour


Hi Sir,

The TDS level in water is 1200 here. We saw some with floating materials after boiling the water. Please suggest which one will be best and secured for health for one year baby.

1. LG

2. AO Smith

3. Havells

4. Blustar

We need 6-10 lt water preserver capacity. We are not worried about hot/cold water. Room temperature water is sufficient for us. We will appreciate your suggestion.

Kitchenarena Team

LG water purifiers are priced a little bit on the higher side and comes with stainless steel tank.

LG Puricare WW180EP (Amazon Link – https://amzn.to/2TDU8kT)

Havells and Blue Star models are also popular and offers 100% RO Purification. You can have a look at the below models.

Havells Max (Amazon Link – https://amzn.to/2CmHrQx)

Blue Star Aristo (Amazon Link – https://amzn.to/2ClTD4f)

Go for the brand that provides timely service at your location.


Can you suggest among Kent Prime Plus, Kent Grand Star and Kent Grand Plus, provided price is not an issue?


Thank you for your blog.
My question is between Blue Star Aristo 7 Litres, Kent Grand 8-Litres, and Havells Max 8-Litres. Which one would you suggest?

Jyotsana Singh

Hello Mitesh,
All the three water Purifier selected by you is RO based water purifier.

Blue Star Aristo, 7L capacity has three segments, RO+UV, RO+UF, RO+UV+UF. All the minerals (good or bad) is flushed out from your RO purifier. The water collected in your tank will have least amount of mineral content. But.

Havells Max 8L comes with RO+UV+Mineralizer, where flushed mineral from your water is compensated with good minerals by additive mineral cartridge.

So I will suggest you to not compromise with quality of water as Havells Max Water purifier will provide Safe and Healthy water for you and your family.


Hi Sir,

While going through the Kent website, I found that they have listed Prime+, Grand Star, Supreme+ and Pride+ as the best selling-models. How do these models compare with the Grand+ Model which you have reviewed?

I stay in Bangalore. Among Eureka Forbes and Kent, which one would you suggest in terms of AMC annual cost and service?

Also, is it better to go for plastic tanks or steel ones?


Jyotsana Singh

Hello Arjun,

If you compare between Eureka Forbes and Kent, It will be suggestible to purchase Eureka Forbes Product. The comparison can be accessed based on Water Quality delivered to you by your water Purifier, AMC and Service.

Plastic tank used to store water in Water Purifier should be food grade(ABS Plastics). It needs less care than steel tank. If there is assurity from Brand about Stainless Steel 304 grade steel, then must go for SS tank. Else other grade of steel may rust after few years of use.


What type of plastic being used by blue star Aristo


You are providing very helpful information through this blog. This will help me to understand different purifiers with different functions. Thank you.

Akhilesh Meena

hello, i have two questions.
1. How Kent Grand Plus water purifier is better than Aquaguard Superb or Aquaguard Magna?
2. Does UF technology necessary in RO+UV water purufiers?

Kitchenarena Team

The Purification process is almost same in Kent Grand Plus and the Aquaguard water purifiers that you have mentioned. Kent Grand Plus is priced a little bit lower than the other two models. Also, the above list of best water purifiers is based on thousands of user reviews that we have collected from Online portals like Amazon, Flipkart and other user review sites.


Can u pls help..which purifier is better with storage or without storage

Kitchenarena Team

Water purifier with storage is the right choice as there will be enough water left in the storage tank even when there is a power cut.


Does there exist a purifier where i can optionally switch on (or off) the RO function?


I have bought Kent Supreme 9 L RO + UV +UF Water Purifier (Tank White) one year ago but I spent almost 3 times major service charges (3800,3800,..2000) in a year and fed up with this model. I was not taken AMC hence spent lots of money. Now, I am planning to go for a new one.

Is it advisable to go for a new brand or repair the existing one? What is your feedback on Kent Supreme model?

PS: I stay in 11th floor flat.


Never Buy Pureit Marvella RO + UV. I am facing the same problem as of yours. Everytime I repair after few months another problem occurs. Cartidge replacement costs are also on higher side.


My water purifier is not woeking well …plz tell which one i shoud buy under 10000

Ro+uv +tds


What about HAVELS water purifier

Jyotsana Singh

Havells have launched five segments of water purifier ranging from UV+UF, RO+UV+minerallizer, Under Sink RO+UV and premium model Digitplus and Digitouch.

As being expert of water treatment and analysis, I feel Havells Water purifier’s design, aesthetic and performance wise a good product. It don’t compromise to provide Safe and Healthy drinking water as per IS standard. Mineralizer add back the good minerals lost from your water by RO membrane. No bypass, no loss.

Having faith in Havells brand and promised service, you can blindly buy Havells Water Purifier which suits your budge.

Prasanna kumar

Our bore water contains limestone can anyone please suggest best water filter that can remove limestone (budget is around 30-35k). if possible a purifier that can dispense cold water also.
Thought of cuckoo but i dont know if their after sale service is good or bad.
LG WHD71RB4RP costing around 40k but it has only RO technology is it enough to filter limestone?


Need your advice in selecting a good water purifier. Currently am using Aqua guard. Water in our apartment changes occasionally. Generally the ground water is not much saline.

Advice a water purifier with out much wastage of water.

Kitchenarena Team

Read this post (https://www.kitchenarena.in/check-tds-level-water/) and check the TDS levels in your water source. If the TDS levels is on the higher side, then you have to opt for an RO water purifier. With Reverse Osmosis water purifiers there will be some water wastage but you can make sue of the reject water for multiple purposes like cleaning the utensils, gardening, cleaning the house and more. If the TDS levels are low (below 400 ppm) you can simply install a UV + UF water purifier and there will be no water wastage at all.


Hi Mate,

Need your advice in selecting between the two water purifiers
i) Livpure Liv-Pep-Pro+ ii) Kent Grand
Livpure does not have the TDS controller but Kent Grand has
Livpure reduces the TDS to less than 50. Isn’t it too less for drinking ?

But if we increase the TDS level in Kent Grand, the unprocessed water
will be mixed with RO water. Overall TDS will be higher (e.g.150-200)
but the will the mixed water be pure and safe ? how do we know that it does not have dangerous chemicals since it has not gone through the RO system.

Please give your precious advice as to which of these two I should buy.
since I wish to buy one of them today (27-10-2018)



Hi Chaitanya
HI Rajat
My ques is somehow similar to Rajat
1) won’t a system with TDS controller add unprocessed water to the RO water to make the TDS high?

2.) Let’s think for a while that even though RO removes the essential minerals from water..like magnesium, calcium ….which we can recover from other resources…..what about the PH level? Won’t the RO will give us only acidic water….and acid levels in body are the major factor for many health issues

3) do we have any brand which has following quality in one product?

A) RO process but after RO it adds mineral to water and/OR … A TDS controller but it should not add unprocessed water to the processed water to show the TDS high

B) Even after using RO…it is maintaining PH level…in other words less acidic

Kitchenarena Team

Unless you have very dangerous metals in your water source (Arsenic, Lead) there will be no problem sending some water directly into the UV/UF membrane. This helps in maintaining natural minerals in the water. But, if you are living in a very polluted area or near to a chemical factory, it is better to opt for a water purifier which offers 100% RO purification.

The PH level in the water will be maintained when there are enough natural minerals in the water. There are many water purifiers that offer 100% RO Purification and at the same time, they add natural minerals at the final stages of purification. You can have a look at the below models.
