Best Water Purifiers In India

Not everyone in India has easy access to clean drinking water. Many of us are, therefore, vulnerable to diseases caused by contaminated water. Water contamination is one of the major pollution threats we are staring at. 

Untreated sewage flowing into rivers, presence of organic matter in water and high coliform levels are the major issues. Arsenic contamination is a major concern that we are worried about. 

The image below shows that more than 100 million people live in areas where the water quality is worryingly poor with the levels of water pollution being very high.

This is where water purifiers come into the picture. We just have to get one for ourselves and of course, our families. Can’t take risks when it comes to them, can we?

Water Purifiers in India – The Buyer’s Guide

1. Why Should You Buy A Water Purifier?

While the reasons are many, the main considerations for buying a water purifier are –

  • Protection from contaminated water
  • Avoid tap water with a high content of chlorine
  • Keep your bottles and utensils clean and hygienic

Having said this, you can get a better understanding of why you should buy a water purifier after you have gained an idea of the major impurities found in water.

Also, look into the various sources that make water impure. The image below shall give you an idea. 

Sources of Impure Water

Take note of the fact that water from lakes, harvested rainwater and rivers bear less total dissolved solids.

On the other hand, water consumed from borewells or groundwater has a higher content of total dissolved solids. This water may also contain lead, arsenic, etc. Piped water, which many in India consider safe, is worryingly, especially vulnerable to biological contamination. 

2. What are the various types of water purifiers?

Before buying a water purifier it is desirable that you know what the various kinds available in India are. We begin with:

2.1 Reverse Osmosis Purification

It’s useful to know what osmosis is before we explain what reverse osmosis is. The osmosis process involves the natural flow of water from low solute concentration (low TDS) areas to high solute (high TDS) concentration ones passing through a membrane. The water molecules being smaller pass through the small pores of the membrane while the dissolved impurities are trapped in it. 

2.1.1 Total Dissolved Solids

TDS Measurement

Total dissolved solids (TDS) is a scientific measure of the net amount of substances – both organic and inorganic –  present and dissolved in water in any form – molecular or ionized. The operational definitions involve a particular conditionality that the solids must be minute enough to make it through a 2 mm filter.

TDS Values

Total dissolved solids usually don’t include salinity and are discussed solely for freshwater systems.TDS isn’t generally counted amongst primary pollutants. There is no direct correlation between TDS and health. It is simply an aesthetic indicator of potable water and is used as a combined indicating value of the presence of a broad array of chemical contaminants.

2.1.2 Reverse osmosis, on the other hand, does the opposite. This process involves pressure being applied to ensure that the water molecules flow from high TDS areas to the low TDS ones. The impure water, which is the water with high TDS, is made to flow to the region of low TDS by applying external pressure. In other words, the natural flow of water is reversed. The water, while passing through the membrane, has the impurities left behind. These impurities are let out through an outlet. The image below will make things clear for us.

Osmosis and Reverse Osmosis

As its pros, reverse osmosis water purifiers have the following factors working in their favor. We now take a peek into them. 

  • Not just killing the viruses and bacteria, RO water purifiers also ensure that the dead particles are totally filtered out.
  • It ensures that all harmful elements like lead, arsenic and the dissolved salts are removed from the water.
  • Coming with a mineralizer, RO purifiers ensure that the water retains all its natural minerals.
  • These, being compact is easy to operate and maintain.

On the other hand, the cons of RO water purifiers are:

  • A lot of water is wasted through the reject mechanism
  • It has to be operated with electricity. As such, power cuts, common in India, render it useless every now and then
  • Only about 50% of the water can be used with the other 50% being wasted.

2.2 Ultrafiltration Based Purifiers

Similar to reverse osmosis, ultrafiltration also involves passing the water through a membrane, but with larger pores. While in reverse osmosis, the pores are very small (0.0001 microns), UF uses a membrane with much larger pores (0.01 microns). The flow of water is therefore natural with no external pressure being applied. As such, these purifiers can operate without electricity. The image below shall give things more clarity

Ultrafiltration

To gain a better understanding of which water purifier will be the right purchase, we now look into the pros and cons of ultrafiltration water purifiers.

The pros of using ultrafiltration water purifiers are:

  • Can operate without power: This factor assumes greater significance for anybody in India. Power cuts are common here. These water purifiers work by applying natural gravitational force on the water. As such, ultrafiltration water purifiers are especially useful in smaller towns and villages. 
  • Cleans the water thoroughly: These purifiers not only eliminate germs and bacteria but also remove all the dead particles. With environmental pollution on a continuous rise in India, this factor makes ultrafiltration water purifiers worth a buy.
  • Strong enough to clean even turbid water: These purifiers are known to not only kill germs, but they can also purify muddy water too. We realize that reliable sources of potable water are not always accessible in India. Under the circumstances, the ability of these purifiers to clean even muddy water makes them useful.
  • They never fail: With larger pores; the membranes in these purifiers are sturdier than in other filters. As such, they are not prone to regular damage. These purifiers are therefore a reliable workhorse for every household. 
  • Long-lasting: As these purifiers can be cleaned easily manually, the cleaning is more effective with all the germs being flushed out. That makes these purifiers easy to maintain and they are long-lasting too. 

On the flip side, the cons of using an ultrafiltration filter are:

  • Soluble elements still remain: As the pores of the membrane are large, the soluble dirt in the water is not separated. It passes through the membrane and stays with the water. As such, the purification process isn’t complete. 
  • The odor still remains: As the process of cleaning is natural, any odor that the water may have is retained. This might be a major headache for us in India as even the tap water here has a strong odor in most cities and towns. 

2.3 Ultraviolet Purifiers

Ultraviolet purification uses the process of shooting UV rays at the water killing germs and bacteria in the water. As the process of filtration through a membrane is not a part of this process, purifiers using this method of purification should be used only in areas with low TDS water.

UV Filteration

Coming to the pros of using ultraviolet water purifiers, bear in mind that such purification takes the process of water purification to another level altogether. This is the only process that can effectively destroy microorganisms in your water. So, the pros can be noted down as:

  • Chemical Free: As the water is passed through high-intensity UV rays; there is no use of chemicals. The purified water is, therefore, odor free.
  • Environment-Friendly: As no chlorine is used in the purification of water; there is no emission of any by-products. 
  • Easy Maintenance: All that these purifiers need is an annual maintenance service. This makes it easy to use and reliable. 
  • Reliable and Safe: They work round the clock being a reliable friend of yours and offer unparalleled safety as no chemicals are used. 
  • Clean and Fast: Filters using this method of purification require no cleaning of any messy parts. It is also fast as water passes through the system with no need for any holding mechanism.
  • Low Use of Energy and Helps Conserve Resources: These purifiers use very little power, and they conserve water as there is no wastage.

UV purifiers, despite all their pros, have some cons:

Failure to Treat Dissolved Impurities: While UV purifiers undoubtedly kill bacteria and germs, they fail to treat dissolved elements like fluorides or pesticides. Farmers in India are known to use pesticides widely. UV purifiers might turn out to be toothless after all. 

Failure to Remove Dead Particles: As the purification process involves no filtering, while the bacteria and germs are indeed killed, the dead particles still remain. 

Failure In Treating Dirty or Muddy Water: We should take care to see that the water meant for UV purification is first treated for mud and dirt. Only after that should the water be passed through UV purification. This is because only the process of filtration can separate mud from water.

Unreliable: Running on electricity, they cannot be operated in the event of power cuts. With no internal storage, these purifiers may turn out to be a liability if you run out of bottled water in your house during a power cut.

Not Possible to Know When It’s Not Functioning: As these use UV lights that are not visible to naked eyes, it is impossible to know when the purifier is not working. That’s why; we might end up consuming contaminated water in the event of a malfunction.  

2.4 Tap Mounted Water Purifiers

Comprising of sediment filters that also can treat carbon, these offer the most basic water purification process. These purifiers come with a filter that can remove mud and sand along with chemicals and microorganisms. Users need to fit them directly to the taps. 

An advanced version of tap or faucet-mounted water purifiers are Gravity Based Water Purifiers. These come with two storage units, one for the purified water and the other for the water that is being purified. 

A look into the pros and cons of using these filters show some factors that work in its favor are:

  • Being relatively inexpensive
  • Ability to switch between filtered and unfiltered water
  • Being easy to install
  • Being ideal for drinking and cooking water

There are also certain factors that are a drawback, like:

  • Not fitting into all faucets
  • Decreasing the rate of water flow
  • Filters needing change now and then
  • Could be expensive at times
  • Might take up considerable space

Before we move ahead to deciding which water purifier is the best one for you, we now look into certain points that need consideration before you go ahead and buy one. We should know whether the water we drink is hard or soft. While the municipalities supply soft water, hard water comes from bore wells and may contain metals, arsenic and fluoride. 

  • Consider only RO water purifiers for hard water
  • Soft water does not need the RO water purifier. Opt for UV water purifiers if the water is highly contaminated. 
  • Go for purifiers that combine both RO and UV for hard, contaminated water.

With each water purifier meant to purify a certain kind of water, it is therefore of utmost importance that you know what kind of water is available in your area. Only after getting to know that can you decide on the water purifier that best suits you. 

Your decision should be based on the contamination level and whether the water is hard or soft. The table below will make things clear.

FAQs

1. What problems could untreated water cause?

Untreated water whether supplied by the municipality or drawn from groundwater reserves can contain a wide variety of physical impurities, biological pathogens and dissolved chemicals which may be extremely harmful to your health. Waterborne diseases are one of the leading causes of death the world over and with Jaundice, Cholera, Typhoid, and Gastroenteritis always doing the rounds, one should be careful before consuming untreated water.

2. What are the purification options available?

Untreated water can be purified using a variety of methods like Chlorination, Boiling, Ultra Filtration, Disinfection (UF) via Ultra Violet Light (UV) and Reverse Osmosis (RO). Most modern water purifiers use UF, UV, and RO in a combined and complementary manner.

3. Why is a combination of UV, UF, and RO necessary when UV lights kill all bacteria and viruses?

While it is true that Ultra Violet Light systems can kill living pathogens like bacteria and viruses, it has no effect on the detrimental and potentially dangerous presence of dissolved solids and harmful chemicals present in untreated water. It has no effect on salinity and cannot remove heavy metals, pesticides, rust and arsenic from untreated water.  Only when UV is used with Reverse Osmosis can one be assured of pure and safe potable water.

4. How does Reverse Osmosis complement UV systems?

Reverse Osmosis (RO) systems force untreated water against a semi-permeable membrane which prevents harmful chemical compounds and dissolved solids from passing through. RO in combination with UF and UV systems ensures complete purification of water which leaves almost no impurities in your water. The process removes all organic and inorganic compounds present in untreated water and gives you safe potable water round the clock.

5. How do I purify hard water?

A water softener uses common salt to regenerate an ion exchange resin which results in soft water. Any water purifier that uses nanofiltration and reverses osmosis should soften water with ease.

6. What purifier should I use for soft water?

Soft water is sweet in taste and doesn’t have the harsh bitterness of hard water, but untreated soft water can also be harmful due to the presence of chlorine and pathogens amongst other things. Almost all UV, UF, and RO compliant water purifiers are capable of handling soft water.

7. How often should one change filter cartridges?

This depends on the capacity of your filters. Filtering capacity varies from 2000 litres to over 6000 litres depending on the brand, model and makes of the product you use. The time period within which you will need to change your filter cartridges depends on a wide variety of variables like the quality of the untreated water you use, the number of impurities present in it and your general usage levels. Generally, cartridges are changed every 6 to 12 months.

8. How much energy does the average water purifier consume?

While the net annual energy consumption depends on how hard the purifier needs to work on the untreated supple, on an average, this ranges from around 200 to 300 watts per year.

9. How often should the water purifier be cleaned?

Cleaning depends upon your own preferences and how much time you have available. In general, the tank should be cleaned about once every two months in winters and around once a month during summers due to the corresponding high water usage.

10. Why is after-sale service an important consideration?

Water purifiers need maintenance and servicing periodically. It is essential that your purifier is up to date for it to work efficiently and keep you safe. Opt for brands that have a reputation for responding efficiently to complaints and requests. This makes the entire experience simple and hassle-free.

11. Do water purifiers use safe plastics?

All branded water purifiers use high-quality plastic of the non-toxic variety that is certified food grade. The plastics used are corrosion resistant and have no effect on the taste or the odor of the purified water.

12. How much water can purifiers hold on an average?

The water purifier capacity varies from model to model. Usually, purifiers can hold anywhere between 9 to 20 litres of water on an average.

13. What can one do if their purifier starts leaking?

Leakage is a possible malfunction in water purifiers. If you are experiencing any leakages turn off the power switch immediately. Unplug the power cord and check if all fittings are still correctly placed. If you cannot single out the source of the leak, call your brand’s customer care number and place a repair request.

Verdict

We hope we have given you enough information to help you pick the water purifier that best suits your needs. We have checked a wide range of them, from the advanced, designer products to ones to the economic and effective ones. While some use the latest technologies, others have chosen to fall back on more traditional methods of purifying water. There are a plethora of water purifiers available in India. This guide, we hope, will help you find your way through.

Having said that, we now take the liberty of picking the two which we feel stand out among all the others in the market. The first one we have chosen is the Havells Max 7-litres RO UV Water Purifier, as it offers a very effective and thorough purification of water. That’s primarily because of the extensive seven-stage purification process it uses. It has effective alert mechanisms in place that alert of any contingencies. You won’t be caught unawares when say, the filter malfunctions.

The second best is the TTK Prestige Tattva 2.0 Copper 16-Liter Water Purifier. We feel so as it falls back on the time-tested traditional gravity-based technology to purify water. That’s why the purification process of the water is totally free of chemicals and the copper container adds the health benefits of the metal to the water.

We hope the information we have come up with is useful to you. Good luck with your mission of finding the right one!
