10 Best Water Purifier in India 2021 : Reviews, Comparison and Buying Guide

Best Water Purifiers in India 2021 : Water is the essence of life itself, and it is vital that we have access to clean, drinking water at all times. This is a commodity that you cannot go without, and also one of the most common vectors when it comes to health outbreaks and pandemics. In fact, most of the stomach bugs that you had experienced in the recent past were on account of drinking contaminated water. Of course, you need to boil the water but that alone may not do the trick as some pathogens are known to survive the process.

So to ensure that the water is completely dirt free, disease and pathogen free, you need to filter it before you can drink the same. And let’s face it, no one has ready access to naturally clean drinking water, not unless they lived right next to a Himalayan spring, high up in the mountains. What you need is an RO based form of water purifier, one that utilizes technologies like UF, UV and MF to filter out all the impurities and provides you with 100% safe, clean drinking water.

Which is the Best Water Purifier in India?

But the problem isn’t solved, not in the sense that you may have thought since now, you will have to choose one purifier from the hundreds of branded ones, which are available in India. More often than not, these are often touted as the best. Granted, that nearly every water purifier that gets launched gets billed as one of the best, but in reality, they may not be as effective as some of the other reputed water purifiers in the market. That’s why we have vetted some of the top-ranked water purifiers in the Indian market and, reviewed them below for your ease of mind and convenience. Do check them out and depending on your current budget, purifier functionality, you can select the right one for your home today.

Why do you need a water purifier?

According to the government of India and more specifically, according to the ministry of drinking water and sanitation, more than 4 crores rural Indians regularly, drink metal contaminated water. If you thought that was bad enough, it may shock you to learn that over 6 million tourists visiting India each year, complain of Diarrhea, which had been mainly bought about by drinking contaminated water. This only underscores the fact that waterborne diseases pan India is not an exception but more of a norm.

According to the water Gap, more than 163 million do not have access to clean drinking water, and the number of water habitats that are being affected by metal contaminants, and other impurities are seeing an exponential increase, all across India. Furthermore, this has only served to exacerbate the problem, where cross-contamination often takes place, and more of the public become affected by various water-borne diseases and parasitical conditions, such as cholera, tuberculosis, diarrhoea, typhoid, hepatitis A and much more.

Isn’t boiling water before drinking it, enough?

Of course, then there’s the old wives’ tale as to how just heating up the water should kill all the bacteria and germs contained in it. It may certainly surprise you to know that certain bacteria and pathogens have developed resistance to high temperatures so you cannot be sure that merely boiling water is not going to do the trick. This is why you need a water purifier and a good quality one at that. So, you plan to boil the water for dealing with various pathogens, fair enough but what about the various metal contaminants often found in water, including arsenic and other impurities?

Merely boiling the water is not going to do the trick; you will need to use a good water purifier, preferably a reputed one, which utilizes various filters, including chemical ones, to remove all the impurities from the water. And in the process, it should also help to sanitize the water so that it is 100% safe to drink and free from contamination.

What to consider when purchasing a water purifier in India

When it comes to selecting and purchasing a water purifier for your home, you may want to keep a few factors in mind, so that you choose one that’s perfect for your home.

  • Water quality: The first thing that you need to do is to test the quality of the water at your home. You may source your drinking water from external sources or from wells, sunk in your own home. But irrespective of where you obtain the water from, you still need to get it tested so as to obtain a clear profile of the same. You need to first determine if the water you use comes with high TDS or not, that is, does it come with enhanced salt content? And if it does, then you may want to opt for RO based water purifiers; if your water comes with muted TDS profile and is soft enough, then you can use a carbon filter based water purifier to treat the same. Incidentally, RO stands for reverse osmosis, a process that is often considered to be one of the most effective methods of removing impurities and contaminants from the water.
  • Check water contamination: It is a good idea to test your water so that you will have a better idea of the contaminants contained in the same. Then, you can select a water purifier that is known to be quite effective in removing these contaminants so that you can have access to 100% clean drinking water.
  • Storage capacity: Another important factor that you may want to consider is the storage capacity of the water purifier. It should be enough to meet your daily needs quite effectively. For example, let’s say that your whole family needs to have access to at least 5 gallons of clean, drinking water each day. In that case, you would need to go for a water purifier that is not just effective in purifying the water but also comes with a storage capacity of 5 gallons, which should help you meet your family’s current need for the whole day.
  • Maintenance: It is important that you maintain your water purifier by cleaning it regularly. It would be a good idea to go in for a water purifier that also offers regular maintenance calls and a change of cartridges at least once a year. This should ensure that your water purifier continues to function seamlessly and without a hitch.
  • Warranty: It goes without saying that you need to go in for water purifiers that come with the required warranty. This can vary from one purifier to the next, so choose one that provides you with a complete warranty and has also gotten rave reviews from other customers as well.
  • Cost: The price tag is an important metric as well and one that you need to seriously consider. A few water purifiers come with all the advanced functionality that you need but are also surprisingly affordable. So check out some of the top-ranked water purifiers that we have reviewed, check out its features and main functionalities, its price tag etc. Once you have reviewed all the water purifiers, you need to decide which sounds better to you and opt for the same, at the earliest.

Frequntly Ask Question About Water Purifier

Which water purifier is best for Borewell water?

These days, in cities, most of the home, the water connection is mostly from borewells. There are very few places where the metro water connection is provided in a seamless manner. Reverse Osmosis, Gravity based and Ultra Violet Purification are the three types of water purifier models available in the market. Depending on the TDS level, the water purifier model can be decided upon. If the TDS level is between 200-300 PPM, then a simple gravity-based water purifier model will work. If the TDS level is more than 300 PPM, then Reverse Osmosis/Reverse Osmosis cum Ultra Violet Purification model would do the needful. TDS is nothing but it checks the hardness of the water, the amount of calcium, and magnesium content in it. Even if the water is highly impure and contains a lot of contaminants, then it is better to go for Reverse Osmosis cum Ultra Violet Ray Purification Model. Also, if your borewell water is not filled with the right and required amount of minerals, then the TDS modulator incorporated in these water purifiers increases the level of minerals and adds taste to the water.

Which brand offers the best customer service and after-sales support?

When it comes to providing the best customer service, then Eureka Forbes and Kent are the best out of the lot. There are a lot of customer service professionals who are deployed with the firm and are ready to provide service to the customers free of cost initially and then at very minimal prices as service costs in the later periods. Also, the service professionals are well equipped to handle any kind of trouble the RO purifier encounters in the shortest possible time. Some DIY techniques are provided as well for the customers to rectify certain issues that arise all by themselves.

What is the benefit of buying a water purifier online?

When it comes to buying online, there are a plethora of benefits involved in it. First, the price is way lesser than the price at which it is sold in the brick and mortar-based electronics showroom. Secondly, you can get to see a variety of choices in the water purifier category alone. But there are many chances of you getting confused as to which purifier you need to buy. There are certain attributes of a good water purifier like Alert System, Voltage Fluctuation Guard, Purity Indicator, 100% RO and UV, and TDS Modulator. Depending on your requirement, you need to choose the water purifier with the relevant attributes.

Will I get the free installation and warranty if I buy a water purifier online?

Yes. Be it any electronics you buy online, you can avail free installation and warranty period. In fact, if the product gets delivered with some defect in the manufacture, then you can avail of full money return. The different warranty period is provided for different parts of the water purifier. Sometimes, you are forced to pay to the service professionals when you order for a RO purifier in brick and mortar-based stores, but when it comes to online delivery from any e-commerce site, no such cost is incurred.

What is the maintenance cost of the RO water purifier?

When it comes to the maintenance cost of the RO water purifier, you need to factor in the two types of maintenance provided for the RO water purifier, the first one being the Annual Maintenance Contract and the second one being the regular maintenance charges. The Annual Maintenance contract charges could vary from anywhere between INR 2000 to INR 4000-5000. Whereas, if you are going for a part by part maintenance, then the charges are comparatively less, it ranges between 1000 to 1500. But, in order to ensure smooth working, it is good to go for Annual Maintenance Contract as it works more or less like an Insurance provided to the purifier. When the machine shows any trouble during the Annual Maintenance Contract period, then one can contact the service professional of the company at any time to provide service to the machine.

Why RO water purifiers waste so much water?

It is said that the RO water purifiers waste almost 3 to 4 liters of water to produce about 1 liter of water. The reason for water wastage in RO water purifiers is based on the following factors. The amount of Total Dissolved Solids(TDS), the amount of pressure exerted, and the temperature of the water. There are certain kinds of Dissolved Solids in the water that comes from municipal water bodies and from borewells which are detrimental to human health, in the process of removing those solids, a lot of water gets wasted. The pressure exerted on the water in places where the temperature is very cool is significantly high than during times and places where the temperature is low. When pressure is high, then the amount of water that crosses the membrane becomes very too less.

Is the RO water purifier good for health?

RO Water is way healthier than tap water. The harmful nitrates present in the water are removed during the process and one can consume comparatively safer water. The only set back in RO water is the heavy water wastage. Experts and those who are working in these companies suggest that the wastewater can be used for irrigation and for other daily requirements like washing, cleaning the utensils, toilet flush.

What should be the TDS level of RO Water?

The consumable level of TDS in water is from 150 to 500. Anything below 150 or above 500 is not acceptable and you need to make use of RO water purifier. If the TDS levels in the RO water purifier is more than 2000, then it cannot be purified by RO water purifier. You need to make use of TDS meter and then buy the water purifier that can cleanse the waters of the TDS range.

I am getting a non-branded RO at half the price, should I buy?

It is not a bad idea to get a non-branded RO. This RO is generally manufactured locally. So, the maintenance cost is way less. Also, service can be availed on time and the service personnel is always at your disposal. The RO manufacturer is way too aware of the quality of water in the surrounding and manufactures based on the TDS levels of water.
