How we picked the best water purifier in India for home 2021

If I have to choose a water purifier for home, I will consider two factors:

  1. Initial water quality in my area: This will help me decide which water purification technology or type of water purifier I should bring home. For instance, depending on initial water quality, you may not need an RO water purifier, a simple UF water purifier, or a UF+UV water purifier may be sufficient for you. In many cities, people drink municipal water and they look a water purifier for municipal water; at some places people intend searching a water purifier for borewell water. Similarly, Different water source may require a specific water purifier type, then why always bring the RO water purifier and loose health-essential TDS.
  2. Components in Water Purifier: Once done with purification technology, I will check and compare the details of the elements that lie in the water purifier. Many water purifier manufactures, in order to compete the market-competitions, have been found using poor quality elements. Irrespective of the water purifier brand name, we should make a thorough analysis of the components present in the ro water purifiers. We have taken absolute note of components wile finalizing our list of the “top 10 best water purifier in India 2021”.

In this section, since the water quality is different in different areas, we will be discussing the components that went through analysis while shortlisting the best water purifier in India for home.

Let’s have a look at them:

  • The material of Construction for UV Chamber: The material of construction for the UV chamber should be stainless steel or anodised aluminum at minimum. 
  • The layout of UV Chamber: The layout of UV chambers may come in the horizontal or vertical direction. The horizontal one should be preferred.
  • The UF membrane orientation: The UF membranes are available in straight and spirally laid inside the casing. The spiral one should be preferred.
  • Size of Filters: The larger the size, the better its purification strength and life. best water purifiers in India 2021 usually come with a large filter.
  • TDS Enhancer: Often, it has been found that some RO water purifiers come with TDS controller/ TDS booster. We have assured that these controllers are not just bypass valves. They must not mix the unpurified water with the purified one to boost the TDS content in water. If it’s a Cartridge, then it’s okay, but the cartridges should come with genuine mediums inside. The cartridges must come with naturally extracted ceramics and not the artificial one. 
  • The Material of construction for Storage tank and other Parts: The material used to develop storage tank and other parts should be stainless steel or food-grade plastic. Nothing less than that.
  • Quality & quantity of Activated Carbon in the purifier: Better quality & more quantity of activated carbon results in better absorption of Chlorine and enhanced water taste.
  • Membrane Make & Capacity is another factor that should not be left unexplored if looking out for best water purifier in India for home.

Buyer’s Guide

How to select a Water Purifier

As discussed earlier in this article, the selection of water should involve two essential considerations:

  1. The initial quality of water in your area, and
  2. The Parts that make the water purifier.

We have already discussed the second point above in the “How we picked our top 10 water purifier in India” section; let’s now discuss the first point.

  • If the TDS level in the water in your area is less than 300 PPM, No need of water purifier, provided the water is free from pathogens or better choose a UF Water Purifier that comes integrated with the UV radiation feature.
  • If the TDS level is higher than 300 PPM but less than 2000 PPM, go with a RO+ UV Water Purifier.
  • If the TDS level is higher than 2000 PPM, the domestic Water Purifier may not work. In this scenario, you should buy a water softening solution.

There are many reasons behind the above recommendations. Please continue reading ahead to get thorough know-how.

TDS CONTENT OF WATERRECOMMENDED WATER PURIFIER TECHNOLOGY
TDS<300 PPMUF + UV
TDS>300 PPM but<2000 PPMRO + UV (or RO+UV+UF technology)
TDS>2000 PPMWater purifier not recommended, go with a water softening solution
water purifier recommendation based on TDS content

Let’s start with the characteristics of drinking water.

Characteristics of Drinking water

When it comes to drinking water, three characteristics define its suitability to drink. These are:

  1. Physical Characteristics 
  • It should be Fresh; Colourless; order less
  • It should be free from bodily impurities, i.e., Turbidity or other solid particles
  1. Chemical characteristics

It should be free from hardness: By hardness, we mean the presence of carbonates & bicarbonates, and compounds like sulfates, chlorides, nitrates, etc. Carbonates and bicarbonates of Magnesium and calcium cause temporary hardness in water. They can be removed by simply boiling the water. But to remove the hardness dues to other compounds (permanent hardness), we need to treat the water with certain technological aids (Water Purification technologies). That’s where the water purifiers play a significant role and so has been segregated the best water purifier in India for home use.

  1. Biological Characteristics

It should be free from pathogens: Raw water, during its journey from lakes; dams to the water treatment plant, comes in contact with various mediums. These mediums contain bio-films that constitutes of microorganisms. Not all are harmful to our body. Still, some, usually called Pathogens, cause diseases in the human body, and our drinking water should be free from them.

Impurities in Water

Impurities in water are just the opposite of what the characteristics define. In its natural form, water is free from any content, whether useful or harmful for health. But as it passes through the different mediums, it carries many minerals and natural extracts present on earth’s surface; unfortunately, it takes some impurities. These impurities are mostly the chemical waste from the industries or the human-made contaminants buried with soil. 

impurities exist in three forms in water:

  • Suspended Impurities
  • Dissolved impurities, and
  • Colloidal impurities

Let’s understand them step-by-step.

  •  Suspended impurities: These impurities are found in the solid form in water, as particles.

The suspended particles’ size is 1 Um and above (regarded as suspended up to 10 Um). Their presence in water makes the water Turbid. The physical visibility of the extent of Turbidity in drinking water depends on the amount of suspended impurity in water. Generally, Turbidity is visible in the water when the suspended impurities are more than 5 PPM.

 Some examples of these impurities are: Silt, Clay, sand, decays of vegetational matter, and microorganisms like algae, bacteria, Protozoa, fungi, etc.

  • Dissolved Impurities: The dissolved impurities include:
  1. Organic compounds like pesticides, animal and plant decay deprivation, herbicides, etc.
  2. Inorganic Ions: Some examples of dissolved organic ions are calcium, Magnesium, fluorides, chlorides, sulfates, nitrates, etc.
  3. Dissolved Gases: High concentration of dissolved gases like Nitrogen, Carbon dioxide, and oxygen can alter the PH of water and cause acidity in the human digestive system.
  4. Dissolved impurities constitute to the hardness of the water. It means the more dissolved impurities in water, the harder it will be.
  5. Dissolved impurities in water have a direct relation with the color of the water. The more dissolved solids present in water, the harder it will become, and also the color will tend towards the darker side.
  • Colloidal Impurities: The size of these impurities ranges between .01 um to 1 um (.00001 mm to .001 mm). These impurities are very hard to remove, and their presence in water gives rise to hazardous diseases.

Now, let’s see what the Indian standard regulatory body, BIS, says about drinking water.

Drinking-Water Quality Standards in India

Based on these characteristics and necessity to remove the above-discussed impurities, WHO (World Health Organisation) issues guidelines for setting Drinking Water quality standards, and agencies of different countries set measures for its People. The measures for India has been kept at reference during our selection of the best water purifier in India for home.

These standards vary from country to country.

In India, the Bureau of Indian Standards (BIS) sets quality standards for Drinking Water. The detailed document for BIS standards for drinking water (IS 10500:1991) set in the year 1983 and revised in 2002 can be seen here 

https://bis.gov.in/index.php/standards/ or at http://cgwb.gov.in/Documents/WQ-standards.pdf.

some of the essential parameters in our drinking water that we generally look out for are listed below:

*Acceptable Limit signifies the specific limit beyond which the water quality is not suitable for drinking.

*Permissible limits are the limits up to which the water, though unsuitablebut still may be tolerated in the absence of an alternative source.

From the chart above, we, now, know the different impurities limits that should not exceed in our drinking water.

When we need a water Purifier  

Case I

If your municipal corporation is providing you with drinking water under acceptable limits of impurities ( as recommended by BIS), Do you need to purify the water further in a water purifier?

 The answer comes ahead- read on. 

The status of drinking water changes at your faucet from what it was at the municipal corporation— the reason is its journey from the Municipal corporation to your house, through the pipes.

The water, just after the municipal corporation, is free from bacteria and other pathogens as they add Chlorine to water or make it pass through UV radiation. But as it travels through pipes, it collects the harmful bacteria which get accumulated in pipes and at valves due to biofilm formation on prolonged time.  

Are these bacteria harmful?

No, not all. Some bacteria are good for us.

According to the 2013 issue of Water Science and Technology, four types of bacteria: 

  • Sphingobium
  • Xenophilus
  • Methylobacterium
  • Rhodococcus 

are harmless to the human body. These bacteria, though found in soil, on leaves, and in lakes, if present in the biofilm is not an issue to our body, but these biofilms may contain some diseases causing pathogens. Our drinking water needs to be free from them. The best water purifier in India for home use presented in this report has been found efficient in removing these pathogens.

That’s the reason; I recommend purchasing water purifiers that comes equipped with UV radiation feature. 

One additional thing which I would suggest is, even if your municipal corporation is adding Chlorine under the acceptable limit. Get the water at your faucet tested for its chlorine content. Excess consumption of Chlorine has serious health implications.

So, the answer to the question asked above is: Yes, we may need to purify water further that we receive from the municipal corporation. 

Yet, we may not need a water purifier.

These pathogens can be killed by simply boiling the water.

Case II

If your municipal corporation is supplying water above acceptable limits or if you are using water from some other natural source.

In this scenario, we assume the TDS of water is above 300 PPM, and Now you need a water purifier.

Please refer “How to select water purifier” section above to know which purifier you should choose based on the TDS level in the water.

Now since we know how to choose the water purifier, let’s understand how these technologies matter and how they are different from one another.

Water Purification Technologies in India

1) UV Technology: The UV technology does not remove the dissolved solids or any other suspended impurities in water. It only kills the biological microorganisms in water or damages their DNA so that they do not replicate in our body if consumed. All the water purifiers presented in our list of the best water purifier in India for home comes embedded with the UV technology.

The mastery of this technology is using an Ultra Violet radiation in the wavelength range of 198 nm to 400 nm. The UV rays pass through the water, where it encounters the different germs and kill them or damage their DNA.

Note :

i) When buying a water purifier, always prefer the units which have the UV chambers installed in the horizontal direction. Because when laid flat, there is a swirling motion of water, and an excellent contact ratio between the light and microorganisms is feasible. However, this factor should not become a reason for rejecting a water purifier, which has some other good reasons to buy.

ii) UF Technology: UF (Ultra Filteration) water purifiers purify the water by filtering it under gravity pressure, and hence no electricity is required. And thus, their initial cost is low as compared to the rest technologies of water purification. These are the most suitable water purifiers when it comes to the place where there is no electricity, or the power cuts are frequent. These are the best non electric water purifiers.

How UF Water Purifier works?

In our list of the best water purifier in India for home use, you may have found MF technology. For Instance in the HUL water purifiers. The MF terminology stands for Micro filteration that works similar to the UF technology, the difference lies in the hole sizes inside the membrane. Let’s see how t works?

Water passes through Ultra Filteration semi-permeable membrane bearing micro holes of the size in the range of 0.1 to 0.01 Micron. The holes in the semi-permeable layer are small enough to counter all types of suspended impurities and colloidal impurities, including the harmful bacteria and other microorganisms.

But, they cannot remove the dissolved solids. As a result, the TDS content of water remains more or less the same as what it was before. TDS under the specified limit is a good thing for our bodies. These are the essential minerals that our body needs to function efficiently. But if the TDS content in water is above the recommended limits of BIS, this water Purifier is not suitable to use.

Though it can remove the colloidal impurities, still the possibility of some tiny microorganisms passing through the membrane cannot be ruled out. The smallest known virus, so far (Source: Wikipedia), is 17 NM in dia (equivalent to 0.017 microns), which is close to the size of pores in the UF membrane. Hence it is always recommended to use this purification technology along with a UV radiation chamber.

So, if you have the municipal water supply with the TDS under the recommended limits, you should go with a UVF+UV combination of water purifiers. And, If you are using water from some other source, a well or some pump-driven groundwater. Use this combination of water purifier only if your TDS meter counts safe.

Note:

  1. Make sure you keep a TDS Meter and PH meter in your home. It will facilitate easy checking whenever required, especially when you feel some difference in the taste of your drinking water. we have recommended some best performing TDS meters down below, You may order one from them if you do not yet own one.
  1. A UF water purifier is available in two types-One where the small hollow pipe type membranes lye straight and the second where you get these in spiral layout. Always prefer the later one.
  1. NF Technology:  This is an intermediate technology between UF and the RO. The pores size in NF technology lies in the range of 0.01 microns to 0.001 microns. One of the useful properties of these filters is their ability to retain 40% to 70 % of minerals found as TDS in water. Our body, therefore, doesn’t get deprived of the essential minerals for its functioning. The PH output also is better with NF technology filters.
  1. RO Technology: RO (Reverse Osmosis) technology, by far, is the most advanced technology of water purification. The membrane’s pores are so small that it removes all types of impurities in water. They are around 0.0001 microns small.  All our water purifiers under the list of best water purifier in India for home essentially has the RO technology.

If we talk of the TDS content in an RO purified water, it is very less-around 20PPM to 50 PPM, depending on the original TDS content in water. It removes up to 90 % of TDS in water, thereby leaving a minimal quantity of minerals essential for health. Drinking mineral-less water has its disadvantages. So modern RO purifiers are coming with Alkaline cartridges, which increases the TDS content of water and gives a better PH value water. our recommended best water purifier in India for home use comes equipped with these alkaline cartridges.

Let’s see how they look if we compare them with one another.

Recommended TDS meters

Below are some TDS meters that we recommend as their performance history is impressive.

Frequently Asked Questions

1. What are the benefits of drinking alkaline water?

Experts say that we should drink alkaline water. They cite several reasons in support of their recommendation. Some of those reasons are:

  • Alkaline water regulates the pH level of the human body.
  • Drinking alkaline water slows down the aging process in human beings.
  • The human body produces acidic juices, drinking alkaline water helps neutralise the acidity. It helps in easy digestion of food by our body.
  • Alkaline water increases the viscosity of blood in the human body, thereby it flows more smoothly and is good for peoples who have Diabetes, high blood pressure, etc.
  • Alkaline hydrates have mineral hydrates that are easily absorbed by our body cells. So it is good for people who do a lot of physical works.

Now before we ahead, let’s see how the pH value of water affects our body. It is essential to mention here that excess alkaline water is also not good for our health, especially in the long run. And, the water purifiers that we recommend you as the best water purifier in India for home delivers alkaline water under limit.

Let’s see what problems our body can face if it’s too acidic or if it’s too alkaline.

  • Too Acidic water consumption:

The too acidic content in our body may give rise to problems like Dry coughing, weakness in muscles, Nausea, breathing problems (Frequent sighs), Irregular heartbeats, anxiety, etc.

  • Too Alkaline water consumption:

Much alkalinity in the body may lead to Non-absorption of minerals by our body, especially potassium and calcium. The calcium, instead of going inside the bones, gets deposited on the outer surface of bones.

Another problem that may occur includes Hyperglycemia (Low blood sugar level); You get cramps in the calves, twitching, arthritis, allergies, etc.

So, drinking water under the right PH limits is essential.

2. What is TDS in the water?

TDS, as we know, is the measure of total dissolved solids in water. The total dissolved solids include Impurities like salts, heavy metals like arsenic, lead, copper, Chlorine, etc., and some useful minerals like Calcium, Magnesium, sodium, potassium, phosphorus, etc.

We measure the dissolved solids (TDS) in terms of Parts Per Million (PPM)

1 PPM = 1 Mg/L (Milligram/Litre). 

So when we say that the TDS of some water is 200 PPM, we mean that there is a quantity of 200 Milligrams of dissolved solids in 1 Litre of that water. 

3. What a TDS controller does?

You must have seen, a number of times, that the term TDS Controller/ TDS aduster has been mentioned while discussing the best water purifier in India for home. Now what these TDS controllers do?

The TDS controller regulates the flow of water in a proportion between the UF membrane and the RO membranes to maintain the TDS in the outlet water. For more details, please read our report on “How a water Purifier works?”.

Please note:
Some water purifier selling companies have been found selling water purifiers where the TDS controller directly mixes the unpurified water with purified water. This mixing gives a better TDS in the outlet. Still, it’s a complete compromise to purification technology, and we strongly encourage our readers to avoid purchasing these types of water purifiers and we have not included any such product in our list of the best water purifier in India for home.

4. What is Hydrogen Water?

Hydrogen Water is the natural water that we use in our day-to-day life, with additional hydrogen molecules added to it. The additional hydrogen molecules react with the free radicals that generate during the various metabolic process and mechanisms in our bodies. Some examples of their generation are reduction and oxidation reactions, exposure to radiation; exposure to smoke and pollution; reaction with transition metals like Iron (Fe2+), Copper (Cu +), Manganese (Mn+), etc.

What happens is that the molecular oxygen, available as biradical, takes free electrons and gets reduced to Superoxide & Peroxides. The Peroxides, further, produce Hydroxyl radicals in the presence of Iron & Copper. These hydroxyl radicals are the most reactive of all the Reactive Oxygen Species (ROS). During their reaction, they probably produce most of the oxidation stress in the human body. That’s why too much Iron or copper can increase oxidation stress.

The human body produces Antioxidant enzymes and small molecules that react with the free radicals and gives them hydrogen to make a stable compound. But this process of neutralising the free radical leads to aging in human beings.

Now comes the role of Hydrogen molecules in our hydrogen water. These act as boosters and helps the body neutralise the free radicals without much effort. That’s why it is said to act as an anti-aging element.

Some research agencies have cited many other advantages; still, the sample size, as of now, is not sufficient to support the use of hydrogen water as miraculous. However, the use of hydrogen water has been approved as safe by the FDA.

5. What is MTDS?

The MTDS is a taste regulator system usually found in the water purifiers from Eureka Forbes. What it does is regulate the TDS in the water outlet when the source water comes with up to 2000 ppm TDS. In other words, It allows you to adjust the TDS in the outlet water manually.

6. What is E-Boiling?

E-Boiling is another name for UV technology. Please refer to our UV technology to understand the details.

7. What is Alkaline Pitcher?

A pitcher is a small water storage device. What alkaline pitcher means is a pitcher with arrangements to make the water alkaline in nature. It consists of cartridges. When you fill water in the pitcher through the lid, it passes through the cartridge, increasing the pH level of water.

8. What is GPD?

The full form of GPD is Gallons per day. It defines the purification capacity of a membrane (RO/NF/UF) per day.

 Final Thought and Disclaimer

In the present days, when human life is facing entrenched contamination from all sides, the necessity of eating healthy food and drinking pure water cannot be put aside. As such, water purifiers have gained importance in our lives. But before we bring home a water purifier, it is imperative that we know the mechanism of a water purifier and how it helps us get the right-quality water. The present report on “the best water purifier in India for home” apart from giving a list of top 10 water purifier in India, lays down much-needed information on the best water filter in India.

    • Dear Mr Rajkumar,

      Thanks for appreciating our content and writing to us. In the report above, we have suggested 10 best water purifiers, based on our selection parameters, that involves a multistage purification process i.e. RO+UV+UF, and some even use alkaline cartridges to enrich the purified water with minerals. Your query indicates you do not need an RO. That’s a remarkable thing. It means you stay in an area where the supply water has TDS within the recommended limit. We will try to come up with a similar list for readers like you shortly. Since we have your email now, we will notify you once the report is published

  3. I leaves in such a place where municipal water is supplied with TDS summer 24 and Raining 32, we have bore well also water TDS 182. But we. never use borewell water because sufficient PWD water is supplied to us. So I request you please su3 me good UV UF water purifier I am planning to buy shortly

    Reply
    • Dear Mr Rajkumar,
      With PWD supply water TDS of 24 and 32, the water, indeed, is very safe to drink but may not necessarily be healthy; a little more TDS could have been better. On the other hand, maybe the TDS content of source water is high in your area, and the PWD is assuring at least safe drinking water to its consumers. This is what I am assuming.
      Drinking the borewell water sounds like a healthy idea, as it will give you more minerals. Though the TDS i.e. 186, is well within the recommended limits of BIS guidelines, using a water purifier with UF+UV technology to reduce some TDS and assure pathogen-free water will really be a wise decision.
      We will come up with the best water purifiers for borewell water/the best UF+UV water purifier soon; please cooperate with us till then. Good content needs long research before release, sometimes. This includes finding the best players in a particular segment, analysing them on different parameters, and bringing the best for you.
      But if you are running short of time, I recommend you to go with any one from the below listed 3 best UV+UF water purifiers:

      1. Kent Ultra Storage 7 Ltr, UV and UF Water Purifier
      2. KENT Maxx 7-Litres Wall Mountable/Table Top UV + UF (White and Blue)
      3. AO Smith X2 5 L UV Ultra Violet + UF (Ultra Fine) Black 5 L Water Purifier

      I hope our recommendation will help you obtain the desired results.

      • I am staying in Goa where drinking water supplied from the dams. I think after treating this drinking water is supplied to the consumers of Goawhich is having a very low TDS 24 and 32.i know that it is not good for health, hardly any menerals left in it. but what to do? any way last year April Ishifted to my new house since than we are drinking boiled water and I am in a search of a good UV uf water purifier. you suggest me 3 uv uf water purifier out of that serial number 1 and 2 I know these are good water purifiers but that is not looking good by its design its look like bucket. Should I consider serial number 3, AO Smith X2 uv uf water purifier but in that uv chamber is in vertical position. I will wait for your reply or should I wait for your next artical on uv uf water-purifiers Regards.

        Reply
        • In A O Smith X2 UV UF purifier UV chamber is made of stainless steel or is it made of aluminium. Waisting for your reply. Regards

          Reply
          • Hi! Sorry for the delayed reply, usually we reply within 24 hrs. The material of construction for UV chamber is Stainless steel and it is placed vertically. This is in accordance to a reply by a registered page with the name of AO Smith servicers on Amazon. we cannot not validate the authenticity of the page.
            We have also left a query to AO smith, will update you once we get some reply. Though vertical in position, the AO smith X2 UV + UF water purifier ensures better contact of UV light with water for its design. The water enters the UV purifier through the bottom of the UV chamber and there is a loop at its top. This ensures pressure drop inside the UV chamber and hence better UV to water contact. You may go with it, it is indeed one of the best water purifier in India 2021

  4. Thank you Mr. Aks , it is very hard to find a detailed article like this on internet. Please come up with more articles on water purifiers and water treatment . Also, please uncover the pH factors of water. I think the mineral cartridges in water purifiers makes the water acidic . Please guide a bit on this

    Reply
    • Dear Mr. Rahul, thanks for appreciating our content, we will try to come up with more informative reports on best water purifiers and other water segments. On the 2nd part of your query, I would say you are absolutely right, mineral cartridges may make the water acidic if they are artificial and chemical composed This is where the big brands come into play. Some of them ensures naturally extracted minerals in their cartridges. But still, I would suggest make a personal level cross check with the seller/ manufacturer before buying a water purifier for home.
      Some manufacturers are playing foul, they have slashed the rate of water purifiers and are using good for nothing-type materials. In fact, they harm our digestive system and produces problems like gastrology, acidity etc.

  6. Respected sir,

    My new flat water has tds around 870 to 970. The demo guy from Kent has suggested Kent pride plus model. Can you please suggest which will be best for me?

    Reply
    • Dear Mr Vohra,
      Why Kent pride plus and why not Kent Supreme extra or other water purifiers included in our list of the best water purifier in India 2021.
      Please note, for a TDS of 870 to 970 ppm, it’s right that you should own an RO system. Though UF+UV systems can also do the job, we recommend it better to have a RO+UV system. Companies provide additional UF systems to maintain the outlet TDS; additionally, some provide alkaline cartridges too.
      Hence the water purifier system you should own should contain RO+UF+UV+Alkaline cartridge assembly. Kent pride plus is a similar water purifier, and the demo man has recommended the right system.
      But please wait.
      There are many good options available to kent pride. We have to pick only 10 water purifiers; hence we preferred to include Kent supreme Extra over others from Kent in Our list of Top 10 water purifiers in India.
      The reasons for Including Kent supreme Extra are:
      Kent Pride was introduced in Mid 2018, whereas the Kent Supreme Extra was first available in mid-20. This shift in the model was attributed to making it even better.
      Kent pride is a bit bulky; it weighs around 15 Kg, whereas the kent supreme Extra weighs just 8.5 Kg.
      You get zero water waste technology and 7 stages of purification in Kent supreme extra model.
      One point where Kent pride leads is the free AMC service duration. Kent does not ask you service charge in the Supreme Extra model for 3 years in addition to a 1-year warranty, whereas for the Pride model, kent claims to provide the entire AMC free for 3 years. Still, PLEASE NOTE that there are terms and conditions for this. The company may change its policy anytime, so get confirmed with the customer care executive before you make the deal.
      Mr Vohra, you can make your conclusion and hence decision; we will also recommend reading the other water purifiers details that come with copper technology mentioned above in our report.
      I hope our reply will be helpful to you. Please write to us in case if you have some more queries.
      Thanks

      • Thank you sir for your reply. I have questions regarding HUL pureit. It doesn’t have tds regulator so let’s say of tds 970 it will give output water of 97 tds. So is it safe to drink?
        Also can you please guide about aquaguard royale.

        Reply
        • Dear Mr Vohra,
          HUL has four types of Pureit water purifiers- Cooper RO water purifier, Eco RO water purifier, UV water purifier, and RO water purifier.

          Considering your question for the first two types, which we have included in our list of the top 10 Best water purifier in India 2021 at s/no 1,2 and 4; please note that all these three water purifiers are 7 stage purifying water purifiers. These 7 stages of purification come as a part of their so-called Germkill Kit. The Germkill Kit has the following items.

          Pre-SedimePre-Sediment Filter – 1 No., Pre-RO Carbon Filter – 1 No., Mesh Filter – 1 No., Post-RO Membrane – 1 No., TDS Modulator – 1 No., MF Membrane – 1 No., RO Membrane – 1 No.

          You must have noted a TDS modulator too, and it works in the same way as we have seen in the kent supreme plus; the only difference is the use of MF (Microfilter) instead of UF. You may have read it in our buyer’s guide section stating how UF water purifiers work.
          Both UF and MF are similar type membranes with pores size in the range of 0.1 to 0.01 Micron. So if you are interested in having a water purifier that comes with a TDS modulator/booster, you can choose any one of the two brands.
