Clean drinking water is essential for our health. But not everyone has access to clean water. Some get their water from borewells which can be hard water, while some get municipal water, while a few can get water from dubious sources often contaminated with virus and bacteria.

We took it upon ourselves to help find some of the best purifiers that can give your clean and healthy drinking water no matter what the source of your water.

We put in a week's worth of time in understanding the basic process of water purification starting from the filtering technologies to the actual use of each of them. We even spoke to a home appliances dealer in Sivakasi, popular and multi-brand dealers Girias and Pai Electronics to understand the sales, maintenance, and usefulness of the purifiers.

With all the work we put in we have found three of the best water purifiers in the market for different budgets and users.

​Best RO+ water purifier

Livpure LIV-PEP-PRO-PLUS+ 7 L RO + UV +UF Water

With 7-stage filtration, ability to work with Hard and Soft water and a sleek design the Livpure Pep Pro+ is a great value for money water purifier.

​Best UV water Purifier

Kent Maxx 7-litre UV Water Purifier

With a 7 litre detachable tank, the Kent Maxx is a great option for homes with soft water supply. It is much simpler too requiring less maintenance than the RO/RO+ systems.

​Best UF water purifier

HUL Pureit WPWL100 Classic 23-litre Water Purifier

If you need a purifier that works without electricity and running water and is low on the pocket in terms of buying and running costs than you should get the HUL Pureit. It is simple to use and maintain and can store up to 9 litres of filtered water.

​Why Trust Us?

To find the best water purifier we spend a couple of weeks understanding the various types of water purifiers. We read deep into the technologies and their workings from many reputed websites, Youtube channels, and university reports.

We spoke to offline dealers as well to see the market needs, the service, maintenance and the accessories of the water purifiers.

To shortlist the products we looked for suggestions from various tech review websites. We also shortlisted all the highest rated and review products from Amazon and Flipkart. We then picked the products that had the most number of filtration processes and value for money price.

​How we selected?

Before we started shortlisting water purifiers we wanted to understand the different filtrations technologies like RO, UV, and UF. We started by reading through countless articles explaining their uses, benefits, costs, and usefulness.

Along with reading we also tuned in some Youtube videos that demonstrate the working of these technologies that helped us understand the necessities of multi-stage filtration processes better.

During the process of research, we found a detailed research carried out by the University of Virology, India that pitted different filtration technologies to see how each performed under a controlled testing protocol.

Furthermore, inputs from dealers really helped us look at different technologies and key features to look at before buying a water purifier

Our shortlist for purifiers started by picking the best selling as well as top rated products on Amazon and Flipkart. We also added some suggestions from other tech websites. Our final picks were products that had multiple filtration methods, good reviews and a price that represented good value.

How to choose the best water purifier- inputs from the dealers

Choosing water purifiers is definitely no easy task, from the vast number of filtration techniques and multiple filter technologies, it can be a chore to even understand what a water purifier has and what it doesn't.

Add to that the confusion on which technology to use where and more often than not people will end up buying the wrong sort of water purifier for their homes. So to clear your doubts on water purifier we spoke to dealers of water purifiers in Bengaluru and Sivakasi.

The dealer's first advice was to buy based on two things- the type of water in your area and your future relocation plans. Water, as you know, is split into two types, Hard water (or bore well/ groundwater ) that is taken from the ground directly using a motor and soft water that we get from the municipal corporation through the piped connection.

Now if you receive hard water the only water purifiers you must buy are RO or RO+. For soft water, you can use UV, UF, UV+ and even RO+ purifiers. Now RO+ purifier due to the use of multiple filtration systems makes them possible to be used for any type of water from hard to soft.

The future relocation of your place is an important but often forgotten point before making a purchase. Say you are based in a place with hard water and you decide to buy an RO purifier, while it will do a great job for you there, if you relocate to a city with soft water, the RO purifier will be useless for you. The vice versa is also true in the case of UV or UF water purifiers.

Now if you are unsure about where you will be in the coming time and you need a water purifier that can be used in all conditions, then the dealers highly recommend an RO+ purifier as it can not only purify your water but also soften it (hard water to soft water).

If you are still concerned about the types of filters and the differences between hard and soft water read our dedicated sections below titled “Understanding Water and Purification Techniques

Best RO+ Water Purifier (in detail)

Water Purifier: Livpure


  • 7 Filtration Stages

  • Pleasing design

  • Can soften hard water up to 2000 ppm

  • Well sealed to prevent insects from entering

  • Tap works manually (no need of electricity dispense water)

  • 1-year on-site warranty


  • Lot of water wastage due to RO technology

  • No hot or cold water dispenser

  • Pre-filter is not bundled in the package

The Livpure Per Pro Plus+ has a beautiful sleek design with only the tap and the display adorning the front fascia. Once wall mounted, the design doesn't look out of place as the more boxy water purifiers of the competition. You get a 7-litre storage tank which is made of food-grade material. 

The screen displays useful information like power on indicator, purification process status, and a tank full indicator.

The purifier is an electric one but the tap is not powered so you can store water and use it at your convenience. Customers noted a small but rather important design feature which was the well-concealed nature of the tank which prevents insects and ants from entering.

A closer look at Livpure water purifier: The water Tap

If you live in an area where the water is hard (500+ppm) and filled with contaminants than an RO purifier will benefit you greatly. The Livpure PEP PRO Plus+ is not just an RO, but an RO+ purifier which makes it a jack of all trades purifier. It can be used to purify highly contaminated water, hard water from borewells and also purify soft water without losing its properties.

It comes with a multi-stage purification system that has the three main filtration techniques of RO, UV and UF along with secondary filtration systems like Sediment, Pre-Carbon, Antiscalant and Post-carbon filters. Together all these filters work to remove dirt and grit, bacteria and viruses, chemicals and pollutants from the water.

The main RO filter also reduces the hardness of water if you have borewell water.

But as we said before this can be used with any type of water, so wouldn't use Soft water completely devoid the water of all its TDS and in turn its taste? Yes and No. It's true that using soft water in a conventional RO only system will remove all necessary TDS and reduce its taste.

But hold on as the Livpure Pep is not a normal RO purifier, it's an RO+ which has a taste enhancer filter that adds backs some hard water back to the purified water thus bringing up the TDS level to a safer drinking standard.

Avid users did test this machine with a TDS meter and found water with around 1000 ppm of TDS being softened to 30ppm.

While this purifier does improve upon the standard RO purifiers, it still carries one niggle from RO purifiers. In the process of purifying Hard water 2/3rd of the water is wasted which is quite significant. But there is no workaround for this and all RO purifiers waste some amount of water.

Of all the purifiers in the market, this particular one had the highest ratings and reviews on Flipkart with customers praising its aesthetics, water taste, purification, value for money and the insect-proof design.

Depending on the water you use your filter life will vary. Your main RO and UF filter can last almost a year, while secondary filters may need changing once every 6 months. It is wise to buy an AMC program which will help you in the long run and will also give you a discount on labour charges. Livpure even has an AMC program which offers free labour and spares.

If you are in the market for a water purifier and you need a high-quality product that can work with any type of water than go with the Livpure Pep Pro Plus+. It is a great value for the price of Rs.10499.

Best UV Water Purifier (in detail)

Kent Maxx water purifier


  • UV+UF filtration for a low price

  • No RO means no water wastage

  • Lesser filters mean lesser maintenance

  • Comes with detachable 7-litre tank

  • 1-year on-site warranty


  • Cannot soften hard water

The Kent Maxx is designed to be used with Soft Water (TDS below 300ppm). It has carbon and sediment filters along with UV and UF. This helps in removing dirt, chemicals and bacteria/ viruses from the water. The Maxx purifier comes in Kent’s iconic White and Blue colour body.

The water tank is 7 litres in capacity and can be detached. It's also transparent so you can see if its full or not.

Being a UV purifier there is absolutely no water wasted and the speed of purification is also faster at 60 Litres per hour. In Fact, it can purify almost 5 times faster than an RO purifier.

This purifier was one of the highest rated UV purifiers online with customers being satisfied with the products quality, the usefulness of the detachable tank and the price. For a price of around Rs. 8000, it is a great pick considering the speed of purification and its cheaper maintenance cost.

Best UF Water Purifier (in detail)

​HUL Pureit Water purifier


  • Needs no electricity to work

  • Can store 23 litres of water


  • Not useful for Hard water

  • You need to manually fill it with water

  • Cannot be wall mounted

  • Slow purification

The Pureit is a gravity-based water purifier which means it needs no electricity to work and it has a single cartridge filter which reduces maintenance costs. This purifier costs around Rs.3000 and is designed for soft water only, but its low cost means it is extremely convenient and affordable for most households and hostels.

The total tank capacity is 23 litres and you have to manually fill water into it. Once the purification is completed the water is stored in the bottom 9-litre tank. Purification can take up to two hours.

Each cartridge can purify around 1500 litres (costs around Rs.500). You can even buy a longer lasting cartridge rated at 3000 litres of purification for Rs. 900. There is also a convenient indicator to show the life of the cartridge.

Its compact size and low maintenance make it a great budget purifier for your homes without the hassles associated with RO and UV purifiers.

After sales service​​​​

The Livpure LIV-PEP-PRO-PLUS+ water purifier has a 1-year warranty and onsite installation and service are offered by the company. Overtime with usage the filters in the purifier have to be changed. You can even opt for their AMC programs where the parts and service costs are waived off.

The Kent MAXX too comes with a similar one year warranty and they too offer doorstep service and installation. Kent too offers preventive annual maintenance contracts where the service and parts are waived of if you pick on of their AMC plans.

The Pureit HUL Classic comes with a years warranty and due to its non-electrical working, there are no parts that need maintenance except the germ kill cartridge that can be purchased offline/ online and installed by the user.

​Who our best picks are for?

Livpure Pep Pro Plus+ is an RO+ purifier which makes it great for hard and soft water, mildly contaminated and heavily contaminated water. This basically means you can use it irrespective of the type of water you get.

Kent Maxx is a UV+UF purifier which means it is good for purifying contaminated soft water only. The lack of an RO filter means it cannot soften hard water.

HUL Pureit is a UF type non-electric filter which means it is suitable for only less contaminated soft water.

Understanding Water and Purification Techniques

Let us look at the difference between hard water and soft water.

Hard Water

  • Hard water is basically groundwater and is hence has a high TDS value.

  • TDS (calcium, magnesium, chalk, lime, etc) is what makes water hard

  • Water with TDS value above 500ppm is classified as Hard Water

  • Hard Water causes scaling of metals objects and cannot form lather with soap water

Soft Water:

  • Soft water is basically rainwater collected from various sources likes rivers and lakes, which is consisting of microorganisms on a large scale, but very little TDS hence they are treated with chlorine. 

  • Below 500 ppm TDS

  • Soft water is what we get from Municipal water and it mostly has chlorine, pesticides, herbicides etc.

  • No issues with respect to scaling and lather formation

​Filtering technologies

Now that we know about the types of water, let us see how different purifying technologies purify water.

RO (Main Filter)

  • Kills and Removes all the Bacteria and Viruses from the Water

  • Removes the Dissolved Salts (Makes hard water soft)

  • Removes metals, fluoride, arsenic

  • RO Purifiers has Prefiltration system to work with the Dirty Water.

  • Reverse Osmosis Requires a lot of Water, (for 3 litres of water used only 1 litre is pure and can be used

  • Expensive

  • Requires water & electricity supply

  • Needs installation

UV (Main FIlter)

  • Kills all Bacteria and Viruses but their Dead Bodies remain in the Water.

  • Reliable and cost-effective method

  • UV Water Purifiers can work with Normal Tap Water Pressure.

  • Chemical free, and it does not change the taste and the colour of the water

  • Compact and can be easily maintained

  • Water should be clear for UV to work.

  • Requires Electricity to operate (UV Lamp inside)

  • Cannot remove Dissolved Salts (Cannot make the Hard water soft)

UF (Main FIlter)

  • No Electricity required

  • Kills and Removes all the Bacteria and Viruses from the Water.

  • UF Water Purifiers can work with Normal Tap Water Pressure.

  • Works with Dirty Turbid Water.

  • Cannot remove Dissolved Salts

Activated Carbon (Used as Pre/Post filter)

  • Absorbs pesticides and herbicides, chlorine

  • Works without electricity

  • Improves the taste of water and removes bad smell.

Sediment Filter (Used as Pre filter)

  • Blocks all the dirt, dust, clay, stones etc. that can damage the filters further in the process
  • Can be added as an accessory to any filter

  • Cannot filter microbial contaminants

  • Strictly used as a pre-filter only

Mineraliser filter (Used as Post filter)

  • Used to add taste and enhance pH value of water

  • Uses material like Calcite & Mineral stones to increase the pH (Remove the acidity in water) & Improve taste

  • Some mineral filters come with carbon filtering and hence can replace most post-carbon filters

  • Can be added to the output water of any filter

  • Designed for soft water lacking the necessary TDS

TDS controller (technically not a filter)

  • Used with purifiers to add TDS to water 

  • To be used when soft water is fed to RO/ RO+ purifiers

  • Can be fit as an accessory

​Things to look for before buying Water Filter

Water Type: Hard or Soft water, Use TDS hardness kit to determine hardness value of your water.

  • If TDS is higher than 500 ppm then buy RO/RO+ purifier

  • If Below 500 ppm then go for UV

  • If TDS is below 200 ppm strictly do not buy RO as it will remove the essential salts. A UF water purifier will suffice.

Water Pressure:Please check your water pressure according to which purifier you are buying. If your pressure is higher than required you will need a pressure reducing valve, if your pressure is less you will need a pressure booster pump. (Not necessary for gravity-based water purifiers)

Electricity: For RO & UV purifiers make sure you have continuous electricity backup.

Positioning: There are a few water purifiers that are designed to be stored under a cabinet thus taking less space compared to those that are wall mounted. Also, make sure you have a running water supply and an electric point near the mounting point of the purifier.

Storage Option: Some purifiers store the purified water while others supply direct purified water.

Price: Keep a check on the price of the purifier as higher the price of purifier most probably higher will be the maintenance costs on it.

Service & Part availability: Check if there are installation and service availability in your city

​Final Thoughts

The type of water purifier you choose is based on your budget, your water supply and many other factors.

If you need a purifier for hard water (and soft water) you can get the Livpure Pep Pro+ which has 7-stages of filtration and comes in a sleek looking design. It is decently priced as well at under Rs.10,000.

If you need a purifier for soft water but something a bit more technical then the Kent Maxx UV+UF purifier is what you should get. It comes with a 7-litre tank capacity and comes with a price of Rs.7999.

But what if you get decent water from the municipality and you need a purifier that doesn't break your bank or needs much maintenance. Then you can get the HUL Pureit which is gravity based and hence doesn't need electricity also the cartridges are easily available and can be replaced by the user. Also, it is one of the cheapest ways of getting purified water for your home.
