Which is Best RO Water Purifier In India 2020?

But first let’s understand what is RO?

IF TDS greater than 300 use Ro purifier

Please be advised that water purifier does not mean RO (reverse osmosis), People casually use RO term for all the water purifiers which is quite misleading and can be detrimental to health. RO is just a technology from various type of technologies from water purifiers or you can just consider RO as an one type of water purifier from RO, UV, UF, NF and gravity based water purifier.

And everyone does not need to buy the RO Technology!

What is RO Technology?

Ro semi-permiable membrane

RO (reverse osmosis) is a water purification process for treating heavily contaminated and salty water (mainly invented for marines living on ship to make the ocean water drinkable) in this water passes under high pressure through semi-permeable membrane with pore diameter 0.0001 micron which allows only water molecule to pass through it and impurities such as heavy metal, rust, mud, sand, chlorine, bacteria etc. and essential minerals naturally present in water such as Ca, Mg, K and are good for our health are also filtered out with impurities and are excluded with waste water that comes out of RO purifier.

Who Should Use a RO Water Purifier?

Buy an RO Technology when your drinking water TDS level is greater than 300mg/l

  1. When TDS level is greater than 300mg/L.
  2. If you have hard and salty drinking water in your locality.
  3. If the municipal water you receive has high content of chlorine.
  4. If you have the yellow and foul smell water from well or bore-well in your area.
  5. Use RO if Industrial and polluted water contains harmful chemical such as Lead and Arsenic.

What is TDS and How to measure it?

Total dissolved solids (TDS) as the name represents it is the measure of total dissolved inorganic and organic substances present in water such as salt, sand particles, chlorine, arsenic, lead and all the essential water minerals also such as potassium, sodium, magnesium. So we measure how much of this solid particles are present in per litre of water. Such as if the TDS is 900mg/L, it means 900 mg of impurities+minerals are present in per L of water.And it can be measured with a simple TDS meter which one can simply buy online for under Rs 250. Just dip it in a glass of water you want to test and switch it on, it will show you the reading. Read more on how to measure TDS?

But the question arises,

How much TDS is bad and how much is good?

Acceptable TDS for drinking water in IndiaAccording to WHO and Bureau of Indian Standards (BIS) upto 500mg/L TDS is acceptable and 300mg/L is considered ideal for drinking water.So if you measure your water TDS and it comes out to be more than 300mg/L then you should use the RO purifier and for other reasons mentioned above. and for TDS lower than 300mg/L there are other purification technologies like UV (Ultraviolet rays), UF (Ultrafiltration) and NF which we will discuss later in this article.

Now let’s see some of the best water purifiers in RO technology in India 2020 below.

Why Choose Kent Grand Plus Over Grand New and Grand Star?

Kent Grand Plus which is best water purifier in India has 7 stage purification mechanism with TDS controller which not only highly purifies the water but at the same time prevents essential minerals present in water good for our health.

Kent Grand series are all similar with few differences but we recommend Grand plus because it has ZERO WASTAGE WATER TECHNOLOGY which you you will not find in Kent Grand New because Grand Plus is the latest and Upgraded model of Kent Grand New.

If you are purchasing online you can get confuse that Kent Grand New has more reviews and ratings than Kent Grand Plus, this is because Grand New has been since 2017 or 2018, people are reviewing since then but Grand Plus is the latest model and has been recently added in the e-commerce sites listings.

And we don’t recommend Grand Star because digital display is unnecessary and it just adds up to more cost and further there has been many complains from customers display not working properly and getting defective soon. Some time RO may be working perfectly but it may be showing TDS levels high (like in below image).

Grand Plus Design and Working

Kent Grand water purifier working

Stage 1: Raw water is passed through the sediment filter for removing Sand and Dirt and other inorganic impurities.

Stage 2: Then Passed through Activated carbon filter where other organic impurities like chlorine, etc gets filtered out by sticking on carbon filter which removes the foul smell of water and makes the water taste better.

Stage 3: Then One stream of water is pushed into the RO membrane where the water is passed 0.0001 micron diameter pores, where only water can be passed through these pores and all other organic impurities such as heavy metal Lead and arsenic and salt from hard water are left behind.

Stage 4: The other stream is passed through UF membrane (pore size 0.01 micron) here organic impurities and heavy metals are filtered out but as the pore sizes are greater than of RO membrane, essential minerals good for our health are not filtered out.

Stage 5: After this TDS controller is regulated in such a way to mix water form RO membrane and UF membrane filter that it achieve the desired TDS that you want.

Stage 6: Then filtered water is passed through UV chamber, where Ultra-violet light kills the germs and bacteria present in water.

Stage 7: Then water is passed through another small post-carbon filter to improve the taste of water again because water coming from UF filter will still have some still some chlorine left.

Why Aquaguard Delight/Amaze is the Affordable Best Water Purifier 2020?

Though all three Aquasure Delight, Amaze and Smart plus have same features with minor differences in design we recommend you to buy Delight or Amaze rather than Smart Plus because Delight and Amaze are the latest version and released after Smart plus, Moreover Smart plus uses mineral cartridge to add mineral artificially through chemical balls, whereas, Delight and Amaze uses Manual TDS control to retain the essential minerals and Post carbon filter instead of mineral cartridge to improve taste of water.

The filter cartridges are designed as per the latest standards in industry to last upto 6000 litres. Suppose each member drinks 3L water on daily basis, so for a 5 member family daily consumption comes to 15L/day. Multiplying 15L with 365 days it comes to 5475 litres, so filters can last upto slightly more than a year. So easily suitable for 5-7 member family.

Further, it is very easy to use, you don’t have to take care of switching the plug on/off, you can leave the switch always open, it automatically cuts the power when tank is full and starts automatically at the time of purification and tells you through LED indicators if it is in operation or the water tank is full, it can also be used with invertor connection because it only requires 45W power, thus a best RO water purifier under budget.

And the UV lamp has a life of 8000 burning hours and comes with a beep alarm to notify you at he right time if anything is not right with UV Lamp so to protect you from bacteria and virus in drinking water.

Aquasure Delight is from the leading Aquaguard company, most preferred brand for water purifiers in India which is known for its quick customer and after-sales service with a large service network spread over in 1500 cities thus a best water purifier in India.

Delight/Amaze Working and who should buy this?

The working of Aquaguard Delight is as same of Kent Grand Plus Working with only ultrafiltration (UF) stage missing that’s why we recommend using a Pre-filter with it so if the turbidity in your water is high it does not reaches in end filtered water.

Who Should use aquaguard Delight/Amaze?

Aquaguard Delight is best water purifier for TDS of 300mg/L-500mg/L or if you are recieving muncipal water, that has less dissolved impurities.

If TDS of your water is more than 600mg/L or if you are confirm that your water source is contaminated with Arsenic and Lead you should not opt for this purifier, kent grand plus or aquaguard enhance will be a good fit for you. Because after some percentage of water is bypassed through TDS controller (MTDS) there is no UF filter between MTDS and UV filter so some of the dissolved organic impurities may pass through it in filtered water that alone sediment filter won’t have been able to filter out.

▼ Aquaguard Delight/Amaze - Frequently Asked Questions (FAQs)

What is the difference between Aquaguard and Aquasure?

Aquasure Series is their affordable series built for audience who want only neccessary features so that RO water purifier can fall into their budget, whereas Aquaguard Series has some extra features like UF filter, Mineral Guard technology and Active copper cartiridge, so a little costly than Aquasure Series.

A aquaguard representative will call you by himself in the next two days, if you don’t receive the call, you can call them by yourself also on their toll free no.- 18602661177 OR 7039883333.

Is there a need to install pre filter ? Will I get pre filter with this purifier?

Pre-filter is recommended if your water TDS is more than 900mg/L, It will improve the life of other filters and RO membrane in water purifier.
Pre-filter does not come with water purifier by default, you will be asked if you want to install a prefilter when call for the installation comes.

Why Aquaguard Enhance is in the Best Water Purifier List?

Though it has less storage capacity of 7L in comparision to Kent Grand Plus (9L) but if your family is not too big 7L with 15L/h purifying capacity is the sufficient and makes it compact, occupying less space on the wall.

What makes it a best RO water purifier and differenciates it with Kent Grand is the presence of Active Copper Cartridge in the place of post carbon cartridge which works same as post carbon improving taste and smell of water but with added copper ions to boost your immunity and polishes the water for a sparkling look.

The rest is as same of Kent Grand Plus but it does not comes with any ZERO Water Wastage Technology, so you will have to save the waste water for watering plants or mopping floor or cleaning utensils.

MTDS is the TDS regulator same as in kent purifiers which helps in achieving the desired TDS level good for health (b/w 100-300 mg/l). Though it is written on water purifiers manual TDS control it does not mean that it is something or some setting you can control from outside, manual TDS is set up inside the purifier by the service guy at the time of installation, so tell him what TDS you want between 100-300 mg/L, usually they set it up to 150 mg/L.

Why to Choose Havells Max over Havells Alkaline?

Scientifically the ph of drinking water should be between 6.5-8.5, but recently there has been trend of alkaline water that it is best for health but there has been no scientific proof that if you should not drinking acidic water then you should drink alkaline water that is totally a myth.

Havells Alkaline adjust the ph of water b/w 8-10, usually around 9, that is out of the recommended range (6.5-8.5) for drinking water and moreover it adjust the ph chemically, it is not natural. So Alkaline filter is not a must then why to add more to the cost.

Whereas, Havells max adjust the ph through standard mineral cartridge and Activated carbon filter layer in taste enhancer, its ph value comes in recommended ph range, making it a best water purifier for home use.

You can opt for Havells PRO also if you want to save some more bucks because Revitalizer Cartridge has some benefits but it is also not a must.

Havells Max Working

Stage 1 (Sediment Filter): Filters out dust, clay, sand, silt and other suspended impurities.

Stage 2 (Activated Carbon Filter): Activated carbon adsorbs dissolved organic impurities, chlorine, other impurities on its surface thus also removes foul smell in water if any and improves taste of water.

Stage 3 (RO Membrane): Water passes through very tiny pores of 0.0001 micron in diameter, thus all the impurities and even essential minerals are filtered out, thus a best RO water purifier.

Stage 4 (UV Chamber): then water passes through Ultraviolet (UV) Disinfection Chamber where UV light kills the bacterias and viruses present in water.

Stage 5 (Mineral Cartridge): Mineral cartridge has different layers of ceramics, stones and calcium balls. As the minerals are also filtered out through RO membrane, mineral cartridge adds essential minerals such potassium, calcium, magnesium, sodium etc when water passes through these layers.

Stage 6 (Taste Enhancer): Taste enhancer is like post carbon filter it improves the ph and taste of water and provides the water a sparkling texture.

Stage 7 (Revitalizer Cartridge): Breaks down water molecules and makes them biologically active for better absorption and hydration in human body.

Why Aristo is a best water purifier and how it works?

Those who have tight budget and want to buy branded Ro purifier BlueStar Aristo is your water purifier. It comes with pre-sediment filter that in most of the other purifiers you have to buy it separately.

In its 6 stage purification water is first passed through prefilter for removing suspended solid.

Then passed to Activated Pre Carbon Filter which adsorbs dissolved organinc impurities on its surface like chlorine, flouride and also removes the smell, yellowishness and odor.

Then passed through Finer Sediment Filter of less pore diameter to remove finer dust, sand particles and cyst.

After that water is passed through double layered RO membrane thus removing 96% impurities, but note as RO also filters out essential minerals also water becomes slight acidic here.

Then water is passed through Copper Impregnated Activated Carbon Filter which has antibacterial properties and aqua taste booster inside it for rebalancing the ph of water as after RO membrane water became slightly acidic, so this fixes that.

In last stage water passes through UV disinfection chamber where bacterias and viruses are killed.

Why Pureit Sleek is the best value for money water purifier?

Earlier HUL purifier used to have high price but out of the rising competition in water purifier market HUL pureit has to provide best value in affordable price.

In Pureit Sleek you have all the required filters needed like RO,UV,UF and both the Pre and post carbon filter (with mineral cartridge) with 8L storage capacity (best for upto 8 people) just under 15,000 rupees.

And on the tip of iceberg you get an advance LED alert system that ensures you get alert 15 days before your Germ Kill Kit(GKK- all the filters combined) expires and stops the water in storage tank after filter expires, so you don’t drink unsafe water, but also high maintainance cost.

But this advance alert system calculates the filter life on the basis of pump running hours, it does not take into account the quality of water. The purifier alerts you after 315 running hours and stops filtering water after 330 running hours, but suppose if you don’t have that much high TDS water (like 900mg/l) and have TDS around 300mg/L then filter may still be in good condition but it forces you to change the filter before that.

How to Find a Best Water Purifier for Your Home? – Buying Guide

Below are some quick to the point factors to consider while buying a best water purifier in India, but we have also written a detailed buying guide if you want to know more in deep.

Source of Water, Type of Impurities and TDS Level of Water

First we need to know what kind of water we are getting at our respective homes, then what types of impurities are present in different type of sources, how it affects TDS level then choose the right purification technology according to that.

Below table mentions the different source of water and different impurities found in them.

Source of WaterCommon ImpuritiesTDS Level
Municipal Corporation SupplyVisible impurities: dust particles, rust, etc.

Invisible impurities:
Bacteria & Viruses
Chlorine, bleaching powder

Useful Dissolved Minerals (not impurities):
Calcium, potassium, sodium, magnesium, zinc etc.

approx 300ppm
Borewell/GroundwaterVisible impurities: mud, sand, suspended solid particles etc.

Invisible impurities:
Bacteria & Viruses
Harmful heavy metals and chemical impurities like Lead, Arsenic, Fluoride, Mercury, etc.

Useful Minerals:
Calcium, potassium, sodium, magnesium, zinc etc.

400mg/L-900mg/L
RiversVisible impurities: mud, sand, suspended solid particles etc.

Invisible impurities:
Same as ground water.

Useful Minerals:
Same as ground water

600-900ppm
Lake/PondsVisible impurities: mud, sand, algae, etc.

Invisible impurities:
Very high level of Cysts, Bacteria & Viruses, Protozoa, etc.

900-1000mg/L

Back To Top ▲

Chlorine/Bleaching Powder: You will mainly find chlorine and bleaching powder in municipal supply of water, they are used as chemical disinfectant to kill bacteria and viruses present in filtered water by water treatment plants, it is safe to drink this water but not for prolonged time and moreover the water doesn’t taste and smell that good because of chlorine.

For the municipal water you really do not need a RO water purifier because the municipal water is already treated with coagulation/flocculation, sedimentation, sand filtration and activated carbon adsorption in treatment plant and its TDS level is also kept around 300mg/L, so a UV based Water Purifier or gravity water purifier with some activated carbon filter will be best suitable for municipal water.

Micro-organic impurities such as bacteria, viruses, protozoa, can be found in all sources of water due to rise in water pollution these days and can cause water borne diseases, to prevent this you should use UV equipped Water purifiers.

Heavy Metals like Arsenic, Lead, Mercury are toxic to health these are not found in municipal water but can be found in ground, borewell, lake water espicially if the near water source is exposed to industrial pollution, in this case TDS could range between 400-above 1000mg/l, so the use of RO water purifier is recommended here but with use of mineral cartridge or TDS controller.

TDS Levels and Type of Purification Technologies in Water Purifiers

If you still don’t know what TDS (Total Dissolved Solid) is, please read we explained it above.

Below Image explains Recommended Purification Technology for different TDS levels.

TDS level VS Water purifier technology

Different water purification technologies in water purifiers

Back To Top ▲

RO (Reverse Osmosis) Technology, we already explained it above.

Ultra Filtration Technology has larger pore diameter (0.01 micron) than than that of RO membrane (0.0001 micron) and electricity is not needed as it is needed to force water through RO membrane because of finer pores. UF Tech can be used for TDS level below 300ppm, it can not filter out dissolved impurities so that is why UF Filters are recommended for TDS level below 300mg/L. And thus it also retains minerals.

But it is not always used alone in water purifiers for TDS above 300mg/L you should use RO+UF+UV Tech. and for below 300mg/L use UF+UV water purifiers or gravity water purifiers.

Nano Filtration Technology has pore diameter (0.001 micron) between Ultrafiltration and Ro membrane but is not generally used in water purifiers that is why above 300mg/L TS RO purifier is recommended and below 300mg/L UF membrane.

Ultra Violet Technolgy (UV water purifiers) is used for killing bacterias and viruses, so not used alone it is used in RO+UF+UV or RO+UV or UF+UV configuration and also with pre-activated carbon filters.

Gravity Based Purifiers or Non-Electric Purifiers are use for Low TDS water like municipal water or if your ground water has low TDS, this uses gravity for filtration and no electricity is required for this, water is pored from top and it passes downward through sediment filter with the help of gravity into next chamber of activated carbon filter for removing organic impurities and foul odor and smell and then to UF membrane or other taste enhancer cartridge.

Technical Specifications to Consider

1. Storage Capacity

Water purifiers comes with Storage capacity ranging from 6 liter to upto 12 Liters.

It depends on how much member are in your family or office 6 litre is easily sufficient for 4-6 people, 9 liter is good for below and above 9 litre also.

2. Purification Capacity

It can go from 11L/hour to 20L/hour, purifier with 12L/hour can fill the tank easily in 30 min, generally if the water purifier has more filtration capacity like 20l/h, most probably it is using TDS controller and in case of 11L/h 100% water must be passing through RO membrane that is why it is taking more time.

3. Tank Type

Generally all of the branded purifiers are made of ABS food grade and corrosion free plastic. That is why local purifiers are not recommended they uses cheap plastic and low quaity filters that may actually harm your health, they are just selling the copy of branded purifier.

4. Indicators & Alerts

It is important that you change filter year after year, to facilitate this companies has LED indicators or Beep alarms to indicate that it is time to change filter but if you need a budget water purifier and that purifier doesn’t have filter and UV change indicator no need to worry because even if filter is not working properly you will come to know by the taste and smell of water and keep always a TDS meter (costs around 250 rs) in your home and keep checking water TDS on monthly or weekly basis. If the water smells or if the TDS level is way to above, it’s time for you to change purifier filter.

Back To Top ▲

5. Mount Type

Most of the water purifiers can be used by mounting on wall or just placing it on table Top. But There are also havells like purifer which can be mounted in the corner of walls.

6. Water Recovery / Water Wastage

When the water is forced to pass through RO membrane, the water that passes out of the membrane and go ahead towards storage tank is called recovered water the water that is left behind and exits outlet is the waste water.

Generally 35% of water is recovered from inlet water that means for 1 litre purified water 2 liter water would be wasted.

But there are purifiers like kent grand series which computer control technology for autoflushing and autocleaning of the RO membrane thus letting pass more water through it, Kent water purifiers claims 50% water recovery.

7. Price

Price may go from 5,000-30,000. But with the fierce competition in market purifer prices have come down just like any other electronic items like mobile and LED TVs.

The price mainly depends on the number of filtration stages it has, means more the cartridges more the cost and if it is equipped with digital display or advance LED indicators the price may go up.

You can get all the neccessary features around 18,000-20,000. But if you need more advance features like digital display and Activated Copper ions technology the prices can go upto 30,000.

Warranty and After Sales Services

It is important to choose right brand for great after sales service because it is not a one time buy product, it will require maintenence from time to time, so you need fast and professional service. All the brands that we mentioned in our water purifier list are from well established, old and big companies mostly having service centre in every prominent area.

Frequently Asked Questions (FAQs)

What is a pre-filter, Is it necessary, Should I get it Installed?

water purifier prefilters
Kent and Aquagaurd Pre-Filter

When you get a installation call from any water purifier brand you may be asked if you also want to install a pre-filter with your water purifier, so prefilter is a extra sediment filter that does not come inside the box of water purifier you purchased, it is a separate filter (an add-on) that costs around Rs 800, it will not be free.

So you should use it only when your source of water has a lot of dirt or sand particles or other visible impurities like if you are receiving water from overhead tank or bore-well or high TDS more than 900mg/L, Pre-filter helps in increasing the life of main filters (that can cost upto Rs 2000 per filter) present inside the water purifier by filtering those solid impurities by itself. So it better in this case to pay 800 for a prefilter than to pay 2000 for main filter replacement after some time. Main filter has a life of 1 year but a pre-filter can increase its life upto 2 years, that’s why recommended.

But if you are receiving the water from municipal that water already has a TDS of 300mg/L, there will be no need for a Pre-filter in that case.

Which water purifier is best for Borewell water?

First Buy a TDS meter irrespective of source of water, if the TDS is below 300ppm go for gravity based purifiers or UF+UV purifiers and if above 300ppm then go for any of the RO purifier mentioned in above beat water purifier in India 2020 list.

What are TDS Controllers / Regulator / Modulators?

RO membrane, with impurities also filters out the essential minerals present in water, which is not good for health. So, to maintain the mineral content in water, inlet water is divided into two streams one is passed through RO membrane and the 2nd stream is passed through UF Membrane (does not filters out minerals) and then to TDS bypass wall which controls how much amount of 2nd water stream should be mixed with Main RO water stream to attain the desired TDS level and amount of minerals in water and improves the taste of water too.

There are other water purifiers also which uses passing of 100% water through RO membrane and uses mineral cartridge to maintain the minerals, but TDS controller is the new and widely prefered technology these days.
