Are you looking for the best water purifier for your home?
Well, you have come to the correct place.
These days, installing a water purifier has become essential for every home. Misuse of water bodies, Industrial growth, Increasing population, and environmental degradation has polluted the water.
The main reason why we use a water purifier is to provide our family with 100% Safe and Mineral-rich drinking water and to prevent waterborne diseases.
RO or Reverse Osmosis is the most commonly used water purification in India, suitable for all kinds of water sources like Borewells, River water, or Municipality Supplied water.
RO is a very Robust technology that can purify the most contaminated, even salty water in just one go.
RO Water Purifiers that come with a combination of UV, UF, and MF filters can remove all sorts of impurities like Mud, Sand, Bacteria, Viruses, Cysts, and dissolved salts like calcium, magnesium, potassium and hard metals like lead and arsenic, etc.
You have to be very careful while selecting an RO water purifier because, along with removing contaminants, it is equally important to maintain a good amount of vital minerals like calcium, potassium, magnesium in the water.
The most important thing you have to concentrate on when selecting a water purifier is TDS.
Please don’t get confused.. we will explain in a detailed way.
TDS means “Total Dissolved Solids,” which is the measure of dissolved minerals, salts, metals and impurities in the water.
According to the Bureau of Indian Standards, water upto 500 ppm is safe for human consumption.
The ideal Range of TDS is between 100 and 300ppm. TDS between 300 to 500 ppm is also acceptable.
If the TDS is above 500 ppm, it means the water is Hard and not fit for Drinking.
TDS range below 100 ppm is not ideal as it is devoid of most minerals.
Before ordering a water purifier, the first thing you should do is to find the TDS levels in your water source.
It is very easy to measure the TDS in water; You can purchase a TDS meter for ₹150 or ₹200. Just take a glass of water and insert the TDS meter into it, and it will show you the reading.
If the TDS level is below 500ppm, there is no need to buy an RO water purifier; you can install a UV UF water purifier. If the TDS Levels are more than 500ppm, you need to get an RO UV water purifier.
With so many brands in the market and declaring that their purification technology is best, it gets confusing to choose the right water purifier.
You might get frustrated by various marketing terms like RO, UV, UF, TDS, Cooper RO, Mineral Booster, Mineralizer… But not anymore
This post will explain all the latest water purification technologies in a simple and detailed way.

Why we Recommend Kent Supreme extra
We have been testing Kent RO water purifiers since 2016. Previous models like Kent Pearl, Kent Grand have a faulty design. The components are not tightly packed in those models, so many users complained about cockroaches entering the machine.
Over the years, the design has improved a lot. The Kent Supreme extra comes with a Food Grade Plastic Body, and the components are push-fit which means the purifier is leak-proof.
Coming to the Purification Process, this Kent model comes with a 7 Stage purification process That Includes treatment of the water by Reverse Osmosis, Ultraviolet Bulb, and UF (UltraFiltration) Chambers.
This Model is suitable for all kinds of water sources like Borewells, Overhead tank water, river water, or municipality-supplied tap water. This Kent RO model can even purify water having TDS levels up to 2000 ppm.
Most of the Local RO water purifiers remove all the essential natural minerals from the water along with impurities, and drinking such low TDS water deprived of minerals is not Goof for health.
Unline Local RO Models, Kent Supreme extra comes with a TDS controller that allows for the retention of natural minerals so you can enjoy safe and tasty drinking water.
This Mineral RO Technology is simple. After the pre-filtration, a portion of the input water will be directly sent to UF Chamber, and it will not pass through the RO Membrane. In the final stages, both the water will be mixed and sent to UV Chamber. This is done to retain the natural minerals in the water.
The best thing is, during installation, you can adjust the TDS Controller to set the Desired TDS Level for the output water. It is better if you keep this level around 250-300ppm.
Another Good feature in Kent Supreme extra is In-Tank UV Disinfection. There is a UV Bulb in the storage tank, and there is no chance for bacterial growth, and the water stored in the tank can be used for longer durations safely.
The Storage tank can safely store 8 Litres of water at once, and this Model can purify up to 20 Litres of water in an hour. This model is perfectly suitable for Medium size Indian families. Even if there are frequent power cuts, there will be enough water left in the storage tank.
The Annual Maintenace cost will be around ₹3000. It depends on the input water source and usage. If your input water has excessive TDS levels above 1500ppm, maintenance will be a little bit higher. Otherwise, it is around Rs 3000 per year.
Why is it Good?
- Kent Supreme extra is Fully Automatic and comes with Filter change and UV Fail Alarms that alert you when there is a need to change the filter. The Water purifier will stop automatically if you don’t change the filter.
- The Zero water wastage technology in Kent Supreme is actually Good, but it is not for everyone.
- Zero wastage is achieved by re-circulating the RO reject water into the overhead tank using its own pump. The Reject water pipe will be left in a washbasin or a bucket for other water purifier models.
- If you have an Individual house, you can set up this re-circulation connection to the overhead tank to avoid water wastage. It will not be possible if you live in an apartment complex. In such cases, you can use the drain water for washing or cleaning purposes.
What are the drawbacks?
- For People who don’t have their overhead storage tank, zero water wastage is not possible.
- This Model is priced a little bit on the higher side.
- Alkaline water Term is also a Marketing Gimmick.
If your water source has TDS levels above 400 or 500ppm and you are looking for an RO water purifier with Good Build Quality and excellent purification with mineral-rich water, Kent Supreme is the right choice.
HUL Pureit Copper+ Mineral RO
Best RO Water Purifier With Precise Copper Dosing.

- The annual Maintenance cost is around ₹4000
Now, More water purifier brands are offering copper-rich water, and all of them are not Good.
Drinking water from a copper vessel is an ancient and well established Indian tradition based on Ayurvedic Science. Copper has many added health benefits; a proper amount of Copper in water can improve digestion, aids weight loss, and good for immunity.
During these pandemic times, everyone is looking for immunity, and this is why most of the brands started offering Copper in the Purified water.
Like everything else, excess of Copper in water is also not good for health, and This is why we do not recommend water purifiers that come with a copper storage tank.
Just 2 or 3 Glasses of copper-enriched water per day is more than enough to avail the benefits of Copper.
Why do we recommend Pureit Copper+ RO Water Purifier?
Unlike the models with copper storage, Pureit Copper+ charges RO water with Copper in Real-time while dispensing the water; this is done with the help of a Unique technology called “electrochemical dissolution of Copper in water.”
This technology also ensures you get precise dosing and the right amount of Copper in every glass.
The best thing about Pureit Copper+ is, this water purifier comes with Dual water dispensing option, and you always have the choice to choose RO water, or Copper Charged RO water.
There are two soft-touch buttons; one for dispensing Copper charged RO water and the other for dispensing normal RO water.
There is a hidden drawback for Water purifiers with Touch Controls. The touch controls will not work if there is a power cut, and you can not dispense water even if there is enough water present in the storage tank.
We have been sending feedbacks to all the water purifier brands regarding this, and HUL has considered this aspect. Along with soft-touch controls, you can also install a Manual Tap for this water purifier.
The Tap lets you dispense Normal RO water even when there is no electricity. Please note that this water purifier can dispense Copper charged RO water only when there is electricity as the Copper is infused into the water in real-time.
Installing the Tap is necessary for most of us because there will be frequent power cuts, especially during the summer. If you have an inverter backup or don’t have power cuts, there is no need to install the Tap.
Another common issue with Copper Vessels or Copper Storage based water purifiers is, they require frequent cleaning using salt, lemon, vinegar or tamarind paste to avoid oxidation. As Pureit Copper+ RO adds the Copper to the water in real-time and does not sport a copper storage tank, there is no need to clean the storage tank.
Why is it Good?
- Along with the Added benefits of Copper in the water, the HUL Pureit Copper+ RO water purifier does the job of a Traditional RO water purifier. Like the Kent Supreme model mentioned above, This Pureit model also comes with a TDS Modulator/Controller to retain the natural minerals in the water.
- This Pureit RO comes with a big Storage tank that can hold 8 Litres of purified drinking water. This RO is capable of purifying up to 28 Litres of water in one hour and is perfectly suited for a family of 4 to 6 members. However, the purification capacity depends on external factors like water quality, TDS levels, the life of filters and input water pressure.
- Pureit Copper+ RO not only gives you Safe drinking water but also looks Ultra Modern. The Black and Copper Color combination looks attractive, and you can either place this water purifier on a Table or Wall Mount it.
- The functioning of the Soft Touch buttons is also good. You dont have to press and hold the button to dispense the water. With one touch, this water purifier can dispense the water continuously for 3 minutes. You can stop water dispensing whenever you want by again pressing the button.
- This water purifier will alert 15 days in advance if there is a need to change the filter.
What are the drawbacks?
- This HUL water purifier is Priced on the higher side.
- In the absence of electricity, there is no option to dispense Copper charged RO water; you only get normal RO water.
Points to note
If your input water pressure is less than 10 PSI, you have to install a pressure enhancing pump for this model.
Also, If there is excess TDS above 1000ppm in your water, it is better to install an antiscalant as it will improve the lifespan of the RO membrane.
If Budget is not your concern, the Pureit Copper+ RO is the best RO water purifier for your Home. Along with Stylish looks, you get the right amount of minerals in your drinking water.
Water Purifier Buying Guide
Why do you need a water purifier?
You have hit the nail right on the head by asking this question. The water that is available in our taps is not exactly the best one to drink directly.
This water contains all kinds of contaminants one can imagine. It explains why many people boil water before drinking.
Boiling kills the germs, viruses, and bacteria from the water. At the same time, it kills the taste and flavour, as well but does not remove the salts from the water.
Therefore, one can resort to using water purifiers that can deliver high-quality drinking water that surprisingly, tastes good, as well.
Now the ‘Why’ part of the question is out of the way. Let us now concentrate on what to do before purchasing your water purifier.
Test the tap water
Of course, there are two ways of testing the tap water. One is to use your natural instincts, and the other is a scientific way with the use of a TDS meter or what we refer to as a water testing kit.
The natural way is to smell and taste the water. If it smells or tastes awful, you should go ahead and read the rest of the article.
At the same time, if it smells and tastes good, what should you do? You should still go ahead and read the article thoroughly.
Water that smells and tastes good is not necessarily the healthiest to drink.
Tap water in India contains soluble and insoluble impurities. Despite the municipalities purifying groundwater, the water can pick up contaminants on its way to your home.
It has to pass through pipes and tanks. Pipelines and tanks can be corroded. They can also have a mineral build-up. Both of these factors affect the quality of water.
Secondly, groundwater can have impurities like arsenic, antimony, lead, and so on. It can also contain Totally Dissolved Solids (TDS – we will be using this term frequently throughout the article).
TDS can comprise organic and inorganic salts including calcium, magnesium, potassium, chlorides, bicarbonates, and sulphates. Thus, it is good to use a TDS meter to determine the extent of TDS.
Where can you test the water?
You do not have to go to a laboratory to conduct the test. The TDS meter is a simple tool to use. It gives reasonably accurate results that should enable you to decide the type of water purifier you should have in your home.
How do you use the TDS meter?
A digital TDS meter should not cost more than a few hundred rupees. Invest in one, as it will prove useful to you for life. Here is how you use the TDS meter.
Step 1 – Determine the temperature of water in the following way
- Switch on the TDS meter and press the TEMP button.
- Place the meter inside the glass of water and note down its temperature.
- Return to the TDS mode by pressing the TEMP button again.
Step 2 – Measure the TDS level
- Remove the protective cap of the TDS meter and turn the TDS meter on.
- Immerse the TDS meter in the glass of water up to the maximum immersion level marked on the device.
- If there are any bubbles in the water, stir it gently to get rid of them.
- Wait for about 10 seconds and allow the reading to stabilise.
- Press the HOLD option and remove the device to note down the reading.
Now, you have the reading. What should you do now? This table will give you a good idea about what the reading conveys.
|TDS Level||Reasons for acceptability or Non-acceptance|
|Less than 50||Water with such a low level of TDS does not contain any essential minerals. It will be tasteless. It is not an acceptable range.|
|50 to 150||It is an acceptable level. However, if you have an RO water purifier at home, ensure that the TDS level is not below 80|
|150 to 200||This level is acceptable. Hospitals usually have this level of TDS in their water supply. It is ideal for maintaining cardiovascular fitness|
|250 to 350||Most of the Indian homes have tap water in this range. It is an acceptable range|
|350 to 500||BIS guidelines state that TDS levels up to 500 are acceptable.|
|500 to 900||As this level is not acceptable, use an RO water purifier with TDS controller/mineraliser.|
|900 to 1200||It is better to use an RO water purifier of good quality with TDS controller.|
|1200 to 2000||It is a highly unacceptable range. You will need an excellent RO water purifier that can handle water with TDS levels up to 2000.|
|Above 2000||Most of the RO water purifiers in the market cannot handle such a high level of TDS.|
We shall now look at the type of water purifier you should buy depending on the TDS level in the source water.
|TDS Level||Water Quality||Viruses/Bacteria||Ideal water purifier|
|Below 500||Good||Yes||UV water purifier should be sufficient|
|Below 500||Muddy/turbid||Yes||Go for a UV + UF water purifier|
|Above 500||Good||Yes||RO + UV water purifier with TDS controller/mineraliser should be okay|
|Above 500||Muddy/turbid||Yes||RO + UV + UF water purifier with mineraliser/TDS controller should be ideal|
|Above 2000||NA||NA||Unfit for domestic consumption|
You have done your homework correctly. Now, you know the TDS level as well as the water quality.
You should go ahead and purchase the ideal water purifier. Let us now discuss what these specific terms, TDS, UV, UF, RO, and so on signify. It will help you understand the basics well.
TDS – Totally Dissolved Solids
TDS can come in various forms. We shall now segregate our population into three distinct types
People living in villages and relying on natural sources of water
Village folk usually do not get piped water supply from municipalities. They rely on natural sources of water such as wells, borewells, rivers, and lakes.
These people use well water to cater to all requirements, domestic and agricultural.
If you venture into a village, you will find domestic animals like cows, buffaloes, goats, and dogs sharing the well water with humans. Naturally, there can be high levels of contaminants.
Secondly, industries in the vicinity of the villages dump their toxic wastes into the rivers and lakes.
The groundwater resources also get polluted due to the indiscriminate release of harmful metals like lead, arsenic, mercury, and so on. All these impurities, visible and impurities constitute TDS.
However, one should note that not all TDS is bad. The groundwater contains useful minerals like calcium, magnesium, and potassium, but the harmful TDS makes it necessary for village folk to invest in a good-quality RO water purifier and with a TDS controller.
We shall look into this aspect when we discuss RO water purification.
India has a vast coastal area with millions of people depending on salty groundwater for their consumption needs.
This water has a high level of TDS. Therefore, they should prefer the RO + UV + UV water purifier with TDS controller or mineraliser for domestic consumption.
We shall now discuss the different types of water filtering methods such as UV, UF, and RO. The concept should be clear before you decide to purchase the water purifier of your choice.
Different Types of Water Purification Systems
Gravity-based water purification systems
Old-timers will recall the simple water filter that used to be common in all households. It used to consist of two containers placed one over the other.
The top container used to have water filtering candles. One used to fill this container with the source water. The water seeps through the fine holes present in the filtering candles into the container below.
This water purification system is an example of gravity-based water purification. It is a kind of UF process. UF stands for Ultra Filtration.
The modern-day UF filters have such a membrane that can trap visible as well as ultrafine contaminants to provide water of good quality.
Such water filters are best in areas where the TDS levels are less than 500. Such water purification systems do not require any electricity for its functioning.
Ultra-Violet Chamber water purification water systems
About 30 years back, there were no RO water purifiers in India. People used to rely on the UF process for their water purification.
The turn of the twenty-first century saw the introduction of ultraviolet (UV) chambers as an effective method of water purification. UV purification is an effective method, as it can eliminate harmful viruses and bacteria.
The water passes through a UV chamber that serves its purpose by killing the germs and providing healthy water to drink.
Such water purification systems need electricity to work. Secondly, there is a disadvantage because the UV chamber can kill the germs but not destroy the bodies of the viruses and bacteria.
Of course, that should not affect your health in any way. However, it is better to pass such water through a UF membrane to remove the remnants.
Reverse Osmosis – RO water purifier
To understand Reverse Osmosis, one should be conversant with the principles of osmosis.
This requires us to go back to our school days and reopen the biology books. Osmosis is a natural process where a liquid in an area with a lower concentration tends to move towards an area of higher concentration through a semipermeable membrane.
A simple example of osmosis is when you place a potato inside a glass of water. After some time you will find the vegetable swelling up because the water from the glass seeps through inside the potato.
The potato contains a high concentration of starch. The potato skin acts as a semipermeable membrane. The significance of the semipermeable membrane is that it does not allow the reverse flow of water under normal circumstances.
Reverse osmosis is reversing the process of osmosis. In this process, water moves from an area of higher concentration to that of a lower concentration through a semipermeable membrane.
RO water purifiers work on a similar procedure where the impure water with a higher TDS level passes through a semipermeable RO membrane.
The membrane has millions of small pores through which the salts cannot pass through. The water molecules are small enough to seep through thereby ensuring the elimination of TDS.
However, this process requires the application of pressure. Hence, RO water purifiers come with built-in pumps to quicken the process.
We shall now discuss the working principle of an RO water purifier.
RO Water Purifier – Working principle
The RO water purifiers available in the market employ a six-level or seven-level water filtration process.
Comparison between different water purification systems
We have seen the different types of water purification systems in the above paragraphs. Each of these systems has its advantages and disadvantages. This comparison will highlight the difference between these systems and clear the concept.
RO vs UV vs UF
|RO Water Purifier||UV Water Purifier||UF Water Purifier|
|Requires Electricity to operate||Requires Electricity to operate||No Electricity required|
|Kills and Removes all the Bacteria and Viruses from the Water.||Kills all Bacteria and Viruses but their Dead Bodies remain in the Water.||Kills and Removes all the Bacteria and Viruses from the Water.|
|Requires Electricity to Boost the Tap Water Pressure||UV Water Purifiers can work with Normal Tap Water Pressure.||UF Water Purifiers can work with Normal Tap Water Pressure.|
|Removes the Dissolved Salts||Cannot remove Dissolved Salts||Cannot remove Dissolved Salts|
|RO Purifiers has Prefiltration system to work with the Dirty Water.||Water should be clear for UV to work.||Works with Dirty Turbid Water.|
Frequently Asked Questions
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.
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
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.
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’.
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
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.
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.
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.
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.
You have just gone through the Water purifier buying guide. This guide should help you make an easy decision about opting for the right water purifier for your home.
You can simply opt for an UV/UF water purifier if the TDS levels in your water source is below 500ppm. If the TDS levels are more than 500ppm, you have to install an RO water purifier.
Make sure that your RO water purifier comes with the combination of either TDS Controller or Mineralizer to retain the essential natural minerals.
Most of the RO water purifiers come with UV/UF Combination to ensure that the water is free from all the contaminants.
