The first reason to have purified water is to prevent water-borne diseases at bay. Unclean water can cause an array of problems, and most of them can become deadly. Boiling your water is not enough.

Having purified water makes sure that no contaminants or toxins are present in it. We will also suggest you use filtered water for daily cooking.

Through a rigorous filtration process, a RO water purifier gets removes these substances.

No Unwanted Chlorine

Heavy minerals and chemicals cause these problems. Using pure and filtered water from the water purifier helps you to follow a clean diet. Good Food should always taste as it should.

Increases the Immunity Level

As pollutants have taken over our life, immunity has become questionable. We need water to survive, and it does add to our immunity power. Having unclean water will invariably affect our immune system.

A RO water purifier makes sure that unhealthy substances cannot attack our system. When our body has to fight all the time, it may become too weak to fend at times of emergency. Clean water keeps the system running smoothly without hindrances.

Purified water is free of toxins that may induce inflammation in your body. So, your body will have a proper immunity balance. You may get much fewer body aches and headaches after switching to a purified water source, such as a RO water purifier.

Are you struggling with how to find the best water purifier for your home?

When shopping for one, you can feel overwhelmed by the choices. Every one of them looks promising to work well in your home.

But, you need to pay more profound attention rather than getting swayed by the pep-talk of a salesman. It needs to fit your home and surroundings. One-size-fits-all designs generally do not work well in India.

India’s Department of Consumer Affairs has published a comparative study on choosing a suitable water purifier. So, along with reviews, here are some points to help you find a good water purifier.

buying guide for best water purifiers in India

Analyse the water conditions

The first thing that you have to do is have a look at the water.

How much TDS or total dissolved solids are present in it?

Do you generally use water out of a municipal corporation tap?

Analyzing the water quality helps you to choose the perfect water purifier. At times, you may not even require a model that has several stages of water purifier technology.

The first step is to check the water for any signs of sediments physically. Sometimes water can be murky or have a red tinge hinting at a high TDS. You can get a TDS meter to check the range.

Water with TDS levels above 250 ppm should be treated with an RO water purifier for the best results. People who use water from borewells may have higher TDS levels. For a low TDS level, then you may not need to invest in a hefty multi-staged RO water purifier. A UV + UF water purifier will work just as great. Installing a water purifier at your home can purify the borewell water and make it safe for consumption.

Water inspections in your area will also give you a good idea of the conditions. You may need a more powerful purifier if your area gets hard water. A product like Kent Grand Plus is suitable for such purposes.

Different types of water purifiers

Are you confused about choosing between the different water purifiers?

When choosing a purifier, you need to base it on the area where you live. Some areas require a more robust filtration system compared to other places.

In general, the simplest water purifier that one can have in India is a gravity-based model. These do not require any electricity. Instead, there is a filtration candle that helps to remove harmful pollutants.

It was one of the most common water filters in India. But, with a higher degree of water pollution, these gravity-based filters began to phase out.

In current models, electricity plays a vital role. It helps to draw the water from a pipeline to pump it through different filters to clean it as much as possible.

Many models even combine all the different techniques for better-purified water.

types of water purifiers

Once you have checked the water quality, you need to pick the correct type of purifier. As we have mentioned above, generally, there are three different types of water purification technologies for homes-

  • RO
  • UV
  • UF

But, companies have started to club them together for a better purification process. RO is often connected with additional charcoal filters or UV filters.

The combined variants of different types of water purifiers available in the Indian market are-

  • UV+UF
  • RO +TDS

We recommend choosing the best water purifier in India with RO, UF, and UV purification systems if your house is in an urban area. A multi-stage water purifier clubs the different filtration techniques.

As pollution has become a serious threat, just using one step is never enough. There can be five to eight-stage purification in water purifiers to clean the water.

They do cost a little more because of the yearly maintenance charges. But, prioritizing your health should be the first concern.

Here are the most desired water purifiers as per Indian requirements-

RO (Reverse Osmosis) Water Purifier

RO water purifiers are distinctly standard in India because of their cost-effectiveness. It is the best way to avoid pesky bacteria and sediments from unclean water.

A RO water purifier also works great for areas that have hard or brackish water. The different steps create advanced cleanliness and eliminate any bad taste from purified water.

Two types of RO filters include-

  • Wall Mounted
  • Under Counter

RO water purifiers run on electricity as the water needs to pass through the filters. The rigorous steps followed in RO purifiers eliminate extra minerals, salts, sulfates, etc.

A RO filter includes the following components-

  •  Pre-Filter or Sediment Filter: The larger particles are removed in the pre-filter. It works to get rid of the chlorine percentage.
  • Carbon Filter: As a natural measure, activated carbon removes most bad smells and other organic substances.
  • RO Filter: Purified water comes out clean and fresh after passing through this semi-permeable RO membrane. Total dissolved solids(TDS) drastically reduce after this step.
  • Post Carbon Filter: As a safety measure, the water needs to go through the last filter. Activated carbon traps any lousy odor and color that might remain in the purified water.

One thing to remember about a RO water purifier is its heavy use of water. Apart from giving you freshwater, it also drains wastewater rich with heavy metals. For instance, at least an extra 5 liters is needed to purify and store 5 liters of water in a RO purifier filter.

working of RO membrane in a water purifier
  • RO water purifiers are relatively affordable options.
  • They can remove most impurities, including harmful pathogens.
  • RO water purifiers reduce hardness in water.
  • It purifies the heavy metals present in the purified water.
  • It helps to eliminate any bad taste or odor.
  • It needs electricity all the time.
  • It will waste lots of water. (Try to develop innovative ideas to use the water that drains from a RO purifier).

UV (Ultraviolet) Water Purifier

Ultraviolet filtration is a simple process of the elimination of germs and pathogens. A UV purification lamp fitted inside a purification machine kills the germs to purify the water.

As the water gets pumped into the filter, the UV disinfection light starts its job. Generally, the setup of a UV water purifier is pretty simple.

The steps include:

  • Sediment filter: The bigger particles present in the water get trapped.
  • UV lamp filter: With the potent UV rays, the germs and bacterias are eliminated.
  • Outlet: Through a tap, you can enjoy clean and fresh water.

UV water filters are great for places that do not have heavily polluted water. As it is a simple step, modern purifiers often club it with RO filters. However, UV rays aren’t that helpful in the case of heavy minerals or chemical substances.

  • A UV water purifier is one of the most economical models.
  • It works well for rural areas with cleaner water.
  • A UV water purifier doesn’t need much maintenance cost.
  • The natural minerals remain intact.
  • It doesn’t require lots of electricity.
  • No water gets wasted by this filter.
  • A UV water purifier cannot remove the chemicals from the water.
  • It isn’t great at regular cleaning water of sediments like sand or mud.

UF (Ultrafiltration) Water Purifier

The process of UF generally includes stepwise elimination of different types of dissolved impurities. Several fiber membranes help to clean the water.

Though UF is unable to get rid of chemicals, it works well with sediments of all sizes. Even the tiny microscopic substances get trapped at the end.

UF is often complementary to the RO system. They work similarly and so are also clubbed together in many models. A UF water purifier also works well to filter muddy water. 0.01 micron-sized pores are present in its last fiber membrane. So, most dirt won’t pass through this barrier.

UF doesn’t need electricity, so it is suitable for places where frequent power cuts is a problem. UF filters often come with a gravity-based design. It will help fill up the upper tank so that the clean water gets stored.

  • It can work without electricity. But, newer models include electricity for fast filtration.
  • No chemicals are used while purifying the water.
  • The bodies of germs aren’t present in the purified water.
  • UF filters last for more duration without additional maintenance.
  • Muddy water is easily removed with a UF filter.
  • It cannot trap harmful chemicals.
  • It isn’t as capable as RO water purifiers.
  • Using hard water may ruin the system.
  • The membrane needs frequent manual cleaning.

These are the different types of water purifiers available in India. A water purifier is a good choice if you think about the future. As the state of water pollution rises, it is always better to take precautions.

Alkaline water purifiers have also entered the market. Specific models have heaters to provide hot water. So, the options are endless.

People from urban and semi-urban areas should always look for a multi-stage water purification process. This is valid even if the water appears transparent to your eyes.

The terms RO, UV, UF generally stands for the kind of filtration used inside a system. So, let us have a closer look at each of them.

Maintenance cost is pretty high because of the RO membrane (Rs 4500-Rs 7500 per year). The cost of maintenance is average (Rs 1000-Rs 2000 per year). Low expense on maintenance as compared to RO and UV water purifier.

Components of Water Purifier

Have you ever wondered about the stuff that goes on inside the water purifier?

These machines can range from being tiny to extremely large. There are vital parts of a water purifier that helps them to filter all the extra or impure substances.

There are multiple semi-permeable membranes in a water filter to trap the impurities. The most common water purifier components include-

  • Pre-filters: It is the first step of getting rid of the impurities present in the water. It generally traps the more significant sediments and substances.
  • Filtration membrane: This may include the RO, UV, or UF membrane that takes out most contaminants.
  • Post-filters: As a final check, activated carbon filters often act as the last filtration junction. An activated post-carbon filter can minutely get rid of impurities remaining after pre-filtration.
  • Water Storage tank: It stores clean and pure water.
  • Water outlet or tap: You can fill a bottle or a glass by turning on the tap.
  • Drain line: Current models clean out the machine by eliminating the impurities. So, the drain line helps to filter the dirty water.

Now, the working of a purifier will depend a lot on the model that you have chosen. Some come with a couple of filters, whereas others have more than four.

RO water purifiers are also equipped with a storage tank to store clean water. You should choose a storage capacity according to your daily needs. Because most variants run on electricity, there is no need to add water to the system.

How much water do you need?

Most RO water purifiers can be found with a storage tank. So, you have to find the suitable capacity for your home. It generally starts from 5 L, which is ideal for a single person or two people.

On the other hand, the need for a giant purifier may also arise if you have to use it for cooking. So, please choose a size that fits you well rather than having to change it later.

As water purifiers come to daily use, get a bigger one with high capacity. It also helps to save lots of water in RO machines. Some filters can even go up to 30 L based on one’s need.

Check the Power Requirements

Even though the best water purifiers do not consume much electricity, many people are wary of it. Specific UV and gravity-based purifiers do not require external electricity. But, you do need to load them with water.

However, electricity-based models can pull water even if the pressure is low. So, the choice depends on the efficiency and need of the user.

Certain areas in India face frequent power cuts, and a non-electric model might work there. But, one should also choose a water purifier based on the TDS level of the water. If it is above 300 ppm, go for an electric water purifier because of its higher capacity to purify water.

Non-electric filters cost less than electric water purifiers. But, electric versions do come with much better technology, and they are powerful with more capacity.

Apart from it, also ensure proper water pressure from the overhead tank.

Ensure Durability of the Purifier

Apart from the purification capacity, it needs to last in your household. Getting a water purifier is a long-term investment that will keep us healthy. So, look at its build quality closely.

Most common products have an outer shell of plastic. But that isn’t the end of the world. A high-quality plastic can assure a purifier’s durability.

It allows the technicians to open up the machine easily. But, you can also go for purifiers with a metal body, which does cost more.

Also, spend some time researching the components used inside the purifier. The best water purifier from good brands usually lasts for decades when appropriately used.

Maintenance frequency cost 

How frequent is the maintenance schedule for the water purifier?

You need to know about this to find a suitable model. In contrast, some models require bi-annual servicing.

If that sounds too much for you, choose the one that follows an annual schedule. RO purifiers generally need frequent check-ups if the TDS level in your area is high.

Salespersons often hide one of the high costs of having a water purifier. They need to have annual maintenance where the different filters get replaced. So, your initial prices aren’t the only thing that you need to bear in a purifier.

Most brands will sign you up on an annual contract. It reduces the cost you spend on yearly maintenance while keeping the machine healthy. You can call different brands to inquire about their yearly plans.

Maintenance of multi-stage RO water purifiers costs more. The budget revolves around Rs 2000 to Rs 5000. If you want to cut down on these costs, it is better to select a pocket-friendly model.

Place of Installation and Design

Where do you want to install the water purifier? Do you have enough space in your kitchen?

Generally, people like to install it over their kitchen sinks. But, a model needs to be able to fit in the area. It will also depend on the size of your water purifier.

Many water purifiers are specially designed to fit into corners. So, ensure the space before you randomly place an order. In India, the kitchens are usually small, so there are several designs to choose from.

You should also pay attention to the get-up of the machine if you happen to have a modular kitchen. These days brands have started to manufacture premium water purifiers. Moreover, it is always better to have something tailored to your kitchen.

Warranty and Customer Service

Going in hand with the maintenance cost, you need to have a warranty. Companies like Kent and Eureka Forbes are famous for their extended warranties. It is yet another reason to go for branded water purifiers.

Ensure that a suitable warranty period is provided with the product. Though the pumps last for a prolonged duration, having a warranty helps you and your family in times of problem.

Make sure to follow the maintenance rules of a brand to keep the warranty valid. It is best not to replace original filters with off-market products.

Budget Requirements

Setting a budget is extra essential while buying a RO water purifier. There are times when you might find that the cost of a product has increased due to a tiny change. So, you should smartly choose a water purifier.

RO water purifiers cost more than ordinary filters. On the other hand, UV filters cost the least, and they may run without electricity. But, you can cut down on costs by analyzing the water condition in your area.

Many people also choose to use gravity filters because the maintenance cost is low. In general, purifiers will cost anything between Rs 9000 to Rs 25000. Everything depends on the features and filtration technology.
