Best Water Purifiers in India: 2020 Reviews & Buying Guide

Water Purifiers have become a necessity to prevent waterborne diseases.

For Indian homes, RO in combination with UV or UF is the best choice as it provides 100% contamination free water. Why? Because…

  • RO – It removes dissolved contamination (heavy metals, chemicals) and undissolved impurities (dust, sand, mud)
  • UV – Kills bacteria, virus and other microbes.
  • UF – Filters undissolved impurities. Though this can be done RO, having it reduces the burden and lets RO concentrate more on dissolved contamination.

Some latest models also come with TDS controller and Mineralizer. TDS controller measures the essential mineral content in the output water. Few models use mineralizer cartridge which adds essential minerals to output water, when TDS controller shows less value than standard levels (100 – 250 ppm).

When it comes to price, RO water purifiers cost around Rs. 7,000 to Rs. 25,000 (based on smart features).

If you want affordable water purifier, then go for gravity purification models as they cost around Rs. 1500 to 5,000. However, they can only filter physical impurities like dust, dirt and sand.

Note: With RO purification, water waste is high – because for every 1 liter of pure water, 650ml of water is discarded. This water can be used for cleaning utensils, watering plants and washing clothes.

Other factors to consider are – storage capacity, flow rate, quality and indicators. You can read them clearly in our “Buying Guide.

Along with that, we have also provided a list of Best Water Purifiers In India.

1. Eureka Forbes Aquasure from Aquaguard Water Purifier

Eureka Forbes Aquasure Water Purifier

A trusted brand over 35 years, Eureka Forbes has been successful in making its way into every Indian household. With years of research and development to make potable water safe and reliable, Eureka Forbes presents Aquasure Smart Plus water purifier from Aquaguard.

One of their latest advancement in this sector, the Aquasure Smart Plus is powered by the universal UV+RO+MTDS technology which purifies water from different sources of supply such as borewells, tanks and taps. Working through six different stages of purification, the water purifier has the capability of providing 30 litres of clean and safe water every hour. And that’s why it is our top pick here!

Stage 1: Water undergoes the clarity cartridge filtration process where the I-filter removes larger suspended particles such as sand and dirt from water.

Stage 2: The chemi block filter captures excess chlorine, finer impurities, pesticides and foul odour before moving to the enhancing process in the next stage.

Stage 3: As mentioned, the water now passes through a membrane life enhancer that prevents the scaling of calcium and magnesium salts and enhances the life and quality of the RO membrane.

Stage 4:  The RO filtration process reduces TDS; removes infectious biological agents such as bacteria, parasites and cysts along with the traces of heavy metals such as arsenic, lead, and mercury.

Stage 5: The RO purified water now passes through the taste enhancer cartridge (post carbon filter) that polishes the water by removing organic residues and giving it a cleaner, sparkling look and taste.

Stage 6: The last step involves UV rays disinfecting the RO water.

The smart build and superior design of the purifier make it a compact appliance that can be easily installed in any corner of the kitchen. However, the Aquasure Smart Plus comes with a large 6-litre capacity tank which gets replenished within 15 minutes once the tank is emptied. The purifier also comes with a 6000 litres smart cartridge that gives a year long carefree protection.

Smart LED indicators represent purification process, water pressure and water supply using different colours. The Smart Plus water purifier comes with an auto off feature that helps in switching off the power when the tank has reached its capacity, thus, saving energy.

The smart TDS regulator reduces up to 90% of dissolved salts to provide you with clean and safe water. The purifier holds the capacity to deal with upto 2000 TDS level and as it has a manual regulator you can set the TDS level according to the water supply in your area

Water Purifier Buying Guide

What is a water purifier and how does it work?

As the name implies, it is an appliance developed to purify water. Usually, they contain 2 or more filters. When you turn on the device, water passes through these filters where several impurities and pollutants are trapped. Clear and pure water is expelled to an outlet source.

Is it Really Necessary to Purchase a Water Purifier?

According to research conducted by Indian Government, almost 37.7 million people get affected by water borne diseases (like diarrhea) yearly. As ground water in most of the states have high levels of arsenic and fluoride, health of almost 66 million people is at risk.

Some people use municipal water for drinking. Though this water is treated for cleanliness, the amount of chlorine used to remove bacteria and other pollutants is high. It can have adverse effects on your health.

With these alarming rates of pollution, it has become important to have water purifier in every Indian household.

How to Choose a Water Purifier?

Choosing a water purifier is a challenging task. In order to find out which one is suitable, first you have to determine your requirements. For that, you have to understand different types of impurities, water source and TDS levels.

1. Different Types of Impurities

Quality of water depends on the levels of impurities present in it. Some commonly observed impurities are chemicals, bacteria, virus, sand and mud. These impurities vary depending on the water source like rivers, borewell, ponds, or municipal water.

Common contaminants and their effect on health…

  • Virus like E.Coli – This bacteria is observed in humans, birds and animals. If water contains E.coli, then it represents the presence of feces and sewage contamination. It can affect your healthy by causing diarrhea, viral infections and other GI tract infections.
  • Bacteria – Wear and tear in water supply system, heavy rains are some of the common reasons for water contamination due to bacteria. It is considered harmful for human consumption.
  • Pesticides and Herbicides – If water source runs through any agricultural farm land, then pesticides used while farming can lead to this contamination. Drinking such water is considered fatal.
  • Nitrates – This contamination is also result of excessive use of chemicals in agriculture. Consuming such water leads to Blue Baby Syndrome – which reduces the ability to carry oxygen to different body parts.
  • Chlorine – In order to provide clean water, municipality authorities mix chlorine in the water. Drinking chlorine water daily can lead to several health complications like joint pains, calcium deficiency and others.

Several others impurities are also present in water. Drinking contaminated water can lead to several health complications.

2. TDS Levels – Total Dissolved Salts

This is another important factor to consider while analyzing which water purifier suits your needs. Usually, TDS levels are calculated based on softness or hardness of water. It is measured in PPM (units of parts per million). Softness and hardness of water is determined by the impurities (dissolved and undissolved) salts ratio present in it.

If you water supply comes from underground water, deep dug bore wells or water tankers then it is hard water. Because it contains highest percentage of dissolved salts – magnesium, heavy metals, arsenic, fluoride, calcium. It is not considered as unfit for human consumption. TDS value of hard water is higher than 500 ppm.

However, if your water supply source is rainwater, lakes, rivers, or municipality storage water, then it is considered as soft water. It contains less amount of dissolved salts. Though TDS levels are low (between 150 – 300 ppm), it is still considered as harmful if consumed on regular basis over long term.

Below is table representing average TDS levels, water source and type of impurities.

Water Source

Common Impurities

Water Type

TDS levels

Suitable Purification Type

Municipal Water

Chlorine, microbial, cysts


1 – 200ppm

UV and UF

Ground/Borewell Water

Sand, dirt, potassium, sodium, arsenic, fluoride


200 – 2000ppm

UV, UF, RO & Gravity

Multiple Sources

Microbes, chemicals, chlorine, sand, mud


1 – 2000ppm

UV, UF, RO, Gravity & Regulator

Every RO purifier usually comes with a TDS controller that checks the level from time to time in order to provide you with clean and safe water. If the TDS value is between 50-300 ppm, water is considered to be safe for consumption. Although each purifier has its own capability of reducing the TDS level, most of them reduce impurities from water with up to 1800 ppm of TDS. Check out the TDS regulator capacity and analyze whether that model is suitable for your water source.

3. Different Types of Water Purification Technology

Based on their capability of removing impurities, purification technologies are categorized into four types – RO, UF, UV and Gravity. We have provided a detail description of each purification method below


a. Reverse Osmosis

If you are living in an area with high TDS levels, then RO water purification is the right choice. In this process, water will pass through a fine membrane (measuring less than 5 microns) from low solute to high solute concentration. This is called reverse osmosis concept. It will trap impurities as fine as 0.03 micron.

Impurities collected from this process are collected in separate tank and discarded through different outlet. It is capable of removing impurities like dust, dirt, heavy metals, dissolved salts, and chemicals.

The only drawback of this purification is that it generates lot of waste water. If you live in high TDS levels, then waste water can be higher than purified water quantity. And moreover, it requires continuous electricity supply to operate.

b. Ultrafiltration (UF)

The purification process of UF is much similar to RO process. However, it doesn’t depend on electricity for operating. Unlike RO, UF has filter membrane with slightly larger holes. So, no additional force is required for water to pass through it. Water wastage is also less compared to RO purification.

The main drawback of UF purification is that the membrane has large pores which can only remove physical impurities like and suspended solids like sand, bacteria, cysts, and dust. It cannot remove dissolved salts like heavy metals – which makes it ineffective for purifying water with high TDS levels.

c. Ultraviolet Purification

Water purifier with this technology comes with a lamp that emits UV rays. These rays disinfect microbial impurities from water. But it cannot remove dissolved impurities, just like UF. Hence, it is suitable for purifying only water with low TDS levels. In most of the purifiers, it is provided as additional filter. So, in that way, water is purified in all forms.

d. Gravity Based Purification

If you are looking for just basic purification, then gravity based water purifiers are the best option. They contain candle filters which are also referred as sediment filters. They are capable of removing physical impurities, suspended solids and un-dissolved impurities. They are suitable for tap/faucet water as they contain low TDS levels and no microbes. Usually, gravity purifiers come with 2 storage tanks – one contains filter where you have to add unpurified water. And in another tank, purified water is collected.

4. Other Factors to consider While Purchasing a Water Purifier

Water Purifier Buying Guide

  • Flow Rate

Analyzing suitable flow rate can be a bit tricky. If the flow rate is high, then it can result in unsuccessful purification of water (due to less time). However, if the flow rate is slow, then it takes a lot of time just to provide 1 liter of water – which can be quite frustrating. So, ideal flow rate should solve both these issues. We recommend going for a model with 12 to 15 liters/hr flow rate.

  • Storage Capacity

Purifying water takes time. So, instead of waiting for water while purification, manufacturers have provided a storage tank where purified water is collected. This feature is even more helpful for people who live in area with unreliable water supply or frequent power cuts. For a nuclear family with 4 to 6 members, 6 liter storage capacity is enough. It ensures you will have sufficient purified water whenever required. To prevent any contamination, most of the reputable brands use high quality food grade plastic. This ensures no further contamination of purified water.

  • TDS Controller

TDS controller is one of the most important aspects to check out while purchasing a water purifier. Most of the models that have RO+UV+UF purification technology come with TDS controller. It checks the level of minerals and dissolved salts present in the purified water. TDS value 1 – 250 ppm is considered completely safe to drink. So, compare the TDS levels regularly to ensure the water purifier is working properly.

  • Weight

This feature may seem insignificant to some people but it matters too. Most of the water purifiers in India weigh around 5 to 12Kgs. Models with less weight are suitable for wall mounting so don’t take any space on the kitchen platform. If water purifiers are heavy, then you have to place them on kitchen counter.

  • Display Indicators

Most of the latest water purifiers come with LED indicators which notify the user when tank is full/empty, filter change alert, UV lamp fail, auto-shut off and others. These indicators help us improve to maintain the product properly which in turns increases its shelf life as well.

  • Build

Build quality is very important factors in terms of shelf life and conserving purified water. The outlook appearance surely adds elegant touch to the kitchen interiors. The materials used should be easy to maintain and durable as well. Common materials used for water purifiers are aluminum and ABS. Few latest models are coming up with copper for storage tank. We recommend to avoid choosing a model with aluminum tank as they facilitate scale buildup.

  • Miscellaneous

Before purchasing a water purifier, make sure to check brand reputation, their customer service and whether they provide free installation. Apart from that, also check if the water purifier comes with WQA certification and gold seal mark. Make sure the model you choose has low maintenance costs. If the filters have to be changed regularly, then consider the replacement costs as well. Last but not least make sure it comes with at least 2years warranty period.

Frequently Asked Questions?

1. How to check if the RO is producing excess waste water?

Expelling a lot of waste water is the main drawback of RO water purifier. In most of the cases, to produce 25% of pure water, it expels 75% of waste water. If the TDS levels of your water source are low, then waste water generation will be less too. So, to find out whether your RO water purifier is generating more waste water, check the TDS levels of water source. If the TDS levels are low and still 75% water is wasted, then consult customer service for professional help.

2. What is the shelf-life of a water purifier?

A good trusted brand with all the necessary certifications work impeccably for about 5-7 years. Although frequent filter changes are needed. Factors such as supply water quality, filter, maintenance and mechanism also play an important role in determining its shelf-life.

3. How long can one store water in the purifier tank?

Although most of the brands use food grade plastic to build their storage tanks, it is advisable to use consume the water within three days of purifying it.

4. Electric or non-electric purifiers. Which is better?

Functionality of both the purifiers are the same but differ from each other when it comes to the flow rate, form of filter used and storage. RO+UV filters work best with high TDS level water. However, they need constant supply of electricity and water. RO purifiers even waste a lot of water. On the other hand, non-electric/gravity based filters save water and electricity while their functionality limits only to water with low TDS level.

5. Are TDS and hardness of water the same?

Hardness constitutes a part of TDS but not the other way round. Hardness basically represents the measure of calcium and magnesium salts in water. Whenever hard water percolates, limescale buildup in the tank/membrane can be observed. TDS is the measure of total dissolved salts which constitutes of both organic and inorganic compounds. The dissolved salts include lead, fluorides, sodium, potassium and other minerals along with calcium and magnesium.


Rising levels of contamination in the water sources are of a great concern. Buying a water purifier is inevitable to lead a healthy life. As it is always known, prevention is admired over negligence. The guide covers all the points one requires to analyze the right water purifier for your home.
