14 Best Water Purifiers in India 2021 – Reviews & Buying Guide

Table of Contents

Owing to the scarcity of potable water, water purifiers can now be seen in almost every household. But you would be highly mistaken to think that this was not the case in earlier times. The use of water filters to improve the safety of drinking or bathing water has been traced back to the earliest of civilizations! 

With passing centuries and after tons of experiments in this field, we finally have our very own modern water filters and purifiers. But what separates these two? Water purifiers offer a greater degree of defence by removing not only waterborne protozoa and bacteria but also viruses, unlike water filters. Thus opting for a purifier to keep your family safe and healthy, is the wiser choice. 

There are a variety of good quality water purifiers available in the market. As a consumer, you must select the most suitable among them, for your domestic use, to ensure safety and complete hygiene. The best model for you will depend upon the location of your house and also the type of water supplied. 

But apart from these two variables, there are some basic specifications which you will have to keep in mind while selecting the one for yourself: make sure the model has at least the RO+UV technology, and the filter membrane of the purifier is of very high quality. It should have an in-built TDS controller and must be able to restore essential minerals back into the purified water. 

If you select a reliable brand, chances are you will find water purifier models that will tick all these boxes, which makes it even more difficult to choose the perfect one. So we bring to you the latest (2020) reviews of the 14 best water purifiers in India. Read on, to set up your mind!

Its storage tank can store 5 litres of purified water, which means, you can get purified water even when there’s a sudden shortage of electricity! 

Pureit promises to deliver safe drinkable water with its advanced 6 stage purification technology using RO+MF. The impure water goes through a pre-sediment filter, a pre-RO carbon filter, a post-carbon sediment filter, a reverse osmosis membrane, microfiltration and finally a post-RO carbon filter to get rid of impurities and provide complete protection from all waterborne diseases. 

This purifier’s TDS controller can turn hard water up to 1800ppm into clean soft water, with a purification capacity of 9-12 litres per hour.

Buying Guide for Water Purifiers in India 2020

Water purifiers come in all shapes and sizes. Choosing one from the variety of options available is quite confusing. You need to keep in mind a lot of factors while finding the purifier which is the most suitable one for you. 

Size of the purifier

You can get water purifiers in different sizes. You can get purifiers that are as small as a school bag and even ones that are as long as a short fridge. Depending on the place where you want to keep the purifier, you will have to select one. There are tabletop as well as wall mounting purifiers. You also get ones that can be used in both ways. 

Most purifiers can be mounted on straight walls, but now a few brands have started manufacturing purifiers that can be fitted in any corner. This helps in saving space and are very convenient. If you are interested in wall mounting water purifiers, then you also have to look into its weight. Thinner walls might not be able to support very heavy ones. The weight of domestic water purifiers start from about 1.5 or 2 kgs and can go up to 20 kgs. 

Storage and purification capacity

Storage capacity is a factor that you should check out before setting your eye on any particular water purifier. In some purifiers, some tanks can hold up to 20 litres of water, and some others have a lower capacity. The size of the storage tank goes hand-in-hand with the purification capacity (that is, the quantity of water the filter can purify per hour) of the water purifier.

If you opt for a purifier with a small storage tank, make sure it has a good purification capacity, or else, it will take time to refill the tank. On the other hand, if you purchase a purifier with a big storage tank and a high purification capacity, then wastage of water will increase because you should not be keeping filtered water in the tank for more than 2 days. So opting for a purifier with a storage tank between 7 to 10 litres, and purification capacity of about 8-10 litres/ hour will be beneficial for a family of 4-6 members. 

Purification process

This is another important factor to keep in mind. Specific brands have patented technologies that they use in the purification process. You need to choose one depending upon the quality of the water supplied to your house. 

With the increasing use of harmful chemicals in almost every work of life, we recommend you use a purifier that features a RO membrane which helps eliminate them. Most of the good brands use advanced RO+UV technology which is even more efficient. 

Mineralizers

If your goal is to make sure that your family drinks 100% clean, safe and healthy water then opt for a water purifier that consists of a mineralizer along with RO+UV technology. After a thorough cleaning of the impure water, the mineralizer adds essential minerals back into the water, making the water healthier and rich in minerals. 

Selecting a purifier with mineralised helps in reducing the health risk of your family members because, with each glass of water, they intake minerals that are necessary for maintaining their health. 

Check the TDS level of water

Before you purchase any water purifier, you need to know the TDS level of the water supplied to your house. TDS or Total Dissolved Solids are the inorganic salts and other organic impurities that remain dissolved in water. 

The level of TDS changes with the source of water. In some places it is high, in other places it is low.  Each purifier is capable of controlling the TDS of up to a specific level. If the water supplied to your house has a high TDS content, it is recommended that you get a purifier that can check TDS up to 2000ppm. 

Filter and cartridge life

When you invest in good quality and high-end water purifier, it is obvious that want a product that lasts for a long time. In the case of water purifiers, the first thing that starts decaying is the filters and cartridges. So before buying make sure that they last for at least 1500 litres. 

Maintenance cost

Do not go for water purifiers that are very cheap. Most cheap purifiers have a high maintenance cost because you have to keep changing and reinstalling the filters and membranes inside it. 

Power consumption

Many water purifiers consume a lot of power to operate. On the other hand, you also have purifiers that do not need any electricity to function. And of course, there are many in between! So depending on how much of an increased electric bill you want to pay, decide on a water purifier. 

Price

When you are satisfied with every other aspect of a product, it is most likely that you want you will be looking for a reasonable price. Make sure that the purifier you have your eye on, gives a good value for money, and is worth the price you are paying. It is also essential that you compare the price with other products in the same range. 

How do Water Purifiers Work?

With increasing levels of water pollution, it is becoming really tough to get healthy drinking water. This is precisely why every Indian household nowadays relies on water purifiers. They are responsible for purifying, cleaning and processing the raw impure water before you drink it.

You can get various types of water purifiers, but their basic aim is to deliver 100% clean and healthy drinking water to your family. Water purifiers also make the water safer by removing all kinds of harmful microorganisms that can cause waterborne diseases like typhoid, cholera and others. 

Each of the brands has its very own patented process or purifying water, which is unique. But these innovative purification technologies are basically a restructured version of the age-old water purification process that removes suspended solids, harmful chemicals, organic impurities, gases and other undesirable contaminants from the raw and impure water, to make it fit for drinking. 

This basic structure consists of sedimentation to get rid of suspended impurities, filtration through activated carbon cartridges to remove harmful chemicals, a stage of disinfection that eliminates all bacteria, viruses and other microorganisms from the water, carbon filters and a reverse osmosis membrane that let only clean water flow through their membranes, and finally storing of the purified water. 

No matter which branded RO water purifier you opt for, each of them will compulsorily have these stages. 

Then why should the price of each product be different? It is mainly because of the quality of the carbon filters and the RO membranes used. Most high-quality purifiers use UV filtration to disinfect the water. Along with these stages, some brands add a mineral cartridge to make the water healthier.

This cartridge infuses essential minerals back into the water. Some carbon filters are capable of changing the taste of the water by balancing the pH levels in it. Thus, some purifiers that use them, allow you to set a desirable taste. 

A few water purifiers come with indicators that help you monitor this whole process and they even alert you if any of the internal appliances seem to be malfunctioning. 

Types of Water Purifiers

Modern-day water purifiers can be classified into a few types:

Electric Water Purifiers

This is the most common type of water purifier available in the market. They need a stable connection of electricity to function properly. Most of the advanced features of a water purifier are put to use here. They hardly need any manual assistance since their processes are automated. 

They can support the use of RO+UV technology and also a TDS controller which you can adjust. Good quality RO water purifiers also have a feature used for reducing the wastage of water. Thus they are environment friendly as well. The electric water purifiers also come with smart LED indicators that alert you about filter changes and lets you monitor the filtration process. 

A major advantage of electric water purifiers is their ability to detect any malfunctioning in the purification process and immediately stop the water flow. This ensures, that you never have to drink impure water. One important thing about electric water purifiers is that they require a source of running water to start the process of purification.

Non-Electric Gravity Based Water Purifiers

You can also opt for non-electric water purifiers for your home if you are not interested to pay extra electricity bills! These types of water purifiers are designed to produce a 100% chemical-free drinking water. These purifiers are gravity-based which means, their storage unit is divided into two parts- the upper portion for raw water and the bottom portion for purified water. 

Most gravity-based water purifiers do not support RO+UV technology which is why many customers prefer electric ones over them. Moreover, these non-electric water purifiers are not suitable for water with a high TDS level. If the water you receive in your locality from the municipality has a high TDS content and is chemically charged, we recommend you to go for an electric water purifier. 

Wall Mounting Water Purifiers

In order to save space in your kitchen, wall mounting water purifiers are the best choice. They come in compact shape and size and can fit perfectly. These require proper installation, lack of which might cause leakage problems. They are mostly placed over sinks, that allows the dirty water to flow through or be contained in any vessel for later use. 

Table Top Water Purifiers

Tabletop water purifiers are mostly gravity-based, which means neither do they require a constant source of electricity or running water. Assembling the parts of these types of purifiers are comparatively easy and it hardly requires a formal installation. 

Though you get sleek tabletop water purifiers, they really cannot be compared with the ultra-modern designs of the wall mounting ones. But presently, many brands like Hindustan Unilever, Havells and others have launched water purifiers that have a flexible installation. That is, they can be used as either a wall mounting purifier or a table/countertop one. 

Frequently Asked Questions
