Best Water Purifiers in India – Buying guide and tips

Best Water Purifiers In India 02

You can’t survive without water. You must have access to pure drinking water to stay healthy. Now, in India, water pollution is alarming. Hence, a water purifier is necessary for every Indian household.

Right now, many water purifier brands and their numerous models are available in the Indian market. Everyone claims to be the best. Now the question is which one is right for you.

Do you buy new water purifier every year? Of course not. As a buyer, you would expect that after purchasing a water purifier, it will provide you with continuous service over the next several years.

If you buy a wrong water purifier by falling into the trap of various online offers or listening to a biased sales executive, it will not only ruin your hard-earned money. It will also disrupt your peace of mind. And most importantly, a wrong water purifier will directly affect your health.

You should consider a few essential factors mentioned below while buying a water purifier for your home.

Different sources of water

Different sources of water

Life on earth began with water, and water nourishes life. Life without water is not possible. About 70% of the human body is made up of water. Also, water is present in all plants and animals. That is why water is considered as one of the most essential and valuable resources on earth. Water sources are mainly of two types, namely Surface Water and Groundwater.

What is Surface Water? In short, the water present above the ground is considered as Surface Water. That is, the water contained in the oceans, rivers, lakes, streams and reservoirs is called surface water. The primary source of Surface Water is rain and continuous melting snow in the mountains.

On the other hand, the water present under the ground is called groundwater. That can present in the soil and between rocks under the ground. Groundwater is usually the primary source of water for most of the world’s population.

It is essential to mention here that only 3% of the water present on the earth is freshwater, which is suitable for human consumption. There are countries in the world where groundwater is not accessible. They use seawater to meet their water needs. In this case, salt and other impurities are removed from the seawater by Desalination. And that makes the water suitable for human consumption. From that point, we Indians are fortunate that there is still enough groundwater available in our country.

Causes of water pollution

Causes of water pollution

Water is one of the world’s most valuable resources. We all know how vital water is to our lives. In future, the lack of pure drinking water could endanger our existence on earth. Unfortunately, even knowing this, we are polluting water every day. Water pollution is one of the most severe problems in the world right now. And the problem is increasing day by day worldwide. Many intellectuals even say that the Third World War is about to happen because of drinking water.

Let us now briefly understand why water pollution occurs. Water pollution occurs when various harmful toxins enter and dissolve in water sources such as rivers, lakes, oceans, etc. As a result, all these water sources are contaminated with toxic substances.

But the matter is not confined to Surface Water alone. This contaminated water seeps through the soil and then enters the groundwater. Thus it causes groundwater pollution. And we use that contaminated water for a variety of daily needs, including drinking.

Groundwater pollution occurs for various reasons. The most common of these are municipal sewage and industrial chemical wastes. Besides, the use of excessive chemicals in agriculture causes severe water pollution. In countries like India, pesticides are used extensively in farming. Pesticides contain extremely harmful substances like arsenic, lead etc. All of these toxins eventually dissolve in the water and cause heavy metals contamination in the drinking water.

It is important to remember that all of these toxins cause serious harm to our health. We may suffer severe illness because of drinking contaminated water. Therefore, it is essential to purify the water before drinking.

Types of contamination in drinking water

Contamination of water

Water can be contaminated by various types of pollutants, such as organic, inorganic, radioactive, etc. Typically, the amount of pollutants in the mountains and mountainous areas is negligible. That is why water pollution in those places is very low. On the other hand, the quantity of pollutants is very high in the cities and rural areas, so the water pollution in these places is also very high.

Groundwater is the primary source of water for daily use in most places in India. This groundwater can be contaminated with a variety of pathogenic organisms and toxic chemicals such as pesticides, arsenic, lead, fluoride, etc. Notably, arsenic poisoning in drinking water is one of the major problems in India at the moment, leading to severe diseases like cancer.

The municipalities disinfect the water with chlorine before being supplied. But,
it often goes far beyond the prescribed levels. That’s why you sometimes smell the chlorine in municipal water. It is important to remember that the presence of excess chlorine in drinking water is also detrimental to human health.

We have discussed above that drinking water can be polluted by various types of contaminants such as harmful germs, toxic chemicals etc. There are different types of water purifier for different kinds of pollution.

Before buying a water filter, you should know what kind of contaminants are present in your drinking water. If your drinking water is contaminated by more than one of the pollutants described above, you should buy an RO + UV + UF water purifier.

What is the TDS of water?

TDS meter

TDS refers to the total dissolved solids present in water. In other words, TDS represents the amount of total dissolved solids present in the water.

These dissolved solids are basically some inorganic salts and small amounts of organic compounds. They appear in the water, both for natural causes and for human activities such as urban development and farming. Generally, sodium, potassium, magnesium and calcium are present in the water as natural minerals.

The presence of the right amount of TDS in drinking water is necessary. The reason is that if the TDS is too low, the taste of the water becomes terrible. On the contrary, high TDS value generally indicates the contamination of harmful substances like lead, arsenic, fluoride in water.

Let’s understand the acceptable TDS values ​​of drinking water from the points below.

TDS (mg/ltr)Rating
Less than 300Excellent
300 - 500Good - Acceptable for human consumption
500 - 900Not good - Should not be consumed.
900 - 1200Poor - Unfit for human consumption.
Above 1200Unacceptable

Now the question is, how do you measure the amount of TDS in your drinking water? It’s straightforward. All you need is a TDS meter. You can easily measure the amount of TDS in your drinking water using a TDS meter. Now you can buy a good quality TDS meter at a low price (below Rs 500) from Amazon. And you can use it for years. Along with this, you should have an idea about the safe drinking water guidelines in India.

At present, millions of Indians drink water that contains TDS value over 900. That is not safe for our health at all.

However, it is essential to keep in mind that the acceptable values ​​of the TDS mentioned above are only indicative. Here is one thing you need to understand very well. Suppose you measure the TDS of the water supplied by the municipality and you find that its TDS value is below 900. Does that mean you should drink this water directly? The answer is no. Even in this case, it cannot be said that the water is safe.

That is because an individual dissolved substance is more important than the overall TDS value. You can even find the value of TDS below 300 in your drinking water, which is described above as excellent for drinking. However, the water may contain high amounts of arsenic, lead, fluoride or mercury. In this case, it can be extremely harmful to your health.

It is important to remember that dissolved solids such as lead, arsenic, fluoride, radium, barium, cadmium are considered as slow poison and are much more harmful than bacteria or viruses.

In this situation, you should never drink water without purifying. Now, by installing a good RO water purifier in your home, you can easily remove all of these toxins from your drinking water.

Why do you need a water purifier?

Why do you need a water purifier

As reported by the Ministry of Drinking Water and Sanitation, Govt. of India, approximately 37 million people in India suffer from waterborne diseases due to contaminated water. Also, 1.5 million children die from diarrhoea.

According to the report, 66 million Indians are at danger because of excessive fluoride. Also, 10 million people are at risk due to excess arsenic in drinking water.

As per the reports stated above, Now, In India, the state of the water pollution is alarming. Therefore, every Indian household should adopt a water purification system.

Water purification technology

Currently, we have mainly three types of water purification technology available. These are RO (Reverse Osmosis), UV (Ultra-Violet) and UF (Ultra-filtration), respectively. The working principles of these technologies are different, and each of them has its advantages and disadvantages. Below we will try to briefly give you an idea of ​​how each of these technologies works and their benefits.

RO (Reverse Osmosis) water purification

Presently, RO (Reverse Osmosis) is the most advanced and effective water purification technology. It can efficiently remove harmful contaminants such as chemicals, bacteria, and viruses from your drinking water.

It is particularly important to note that, among the currently available water purification technologies, RO is the only technology capable of removing harmful dissolved solids such as pesticides, arsenic, lead, mercury etc. from water.

Although RO is the most trusted and reliable water purification system worldwide, it has some limitations.

First of all, it is essential to remember that RO purifier needs electricity to function. Also, more water is required for the RO purifier to work. The reason for this is that, in this method wastage of water is much higher than other purification systems.

Typically, the RO water purifier wastes three litres of water to supply one litre of pure water. In this case, 25% of the total input water comes out as pure water, and the remaining 75% goes out as wastewater, which cannot be used for drinking. Of course, you can use this wastewater for gardening or cleaning the floors of your home.

RO purification process

Let’s now see how RO technology works. There are four stages to the RO purification process, which are Pre-Filter, Carbon Filter, RO Filter and Post Carbon Filter, respectively. RO technology uses these different types of filters to purify water.

RO Water Purification

Pre-Filter or Sediment Filter

The Reverse Osmosis purification process begins with the Pre-Filter Method. This process removes large particles present in the water. As a result, dust, sand or other visible impurities are removed from the water. Also, this process reduces the amount of chlorine present in the water.

Carbon Filter

The next stage of pre-filter is the carbon filter. At this stage, the water coming out of the pre-filter process passes through the carbon filter. This method eliminates any organic compounds and odours present in the water.

RO Filter

RO filtration is the most crucial part of this entire purification process. The RO purification process begins as the next stage of carbon filter purification. In this case, the water coming out of the carbon filter passes through the RO membrane.

RO membrane is a plastic filter. It has tiny holes in it that allow only water molecules to pass through it. The molecular size of other pollutants is more substantial than these pores. So, they cannot cross the RO membrane. Therefore, dissolved harmful substances such as arsenic, fluoride, radium, barium, cadmium, cyst are removed from the water. This process also reduces the amount of total dissolved solids (TDS) of water.

Post Carbon Filter

The last step in this whole purification process is post-carbon filter or post filter. In this process, the water coming out of the RO filter crosses through a second carbon filter.

Though at this stage, the presence of contaminants in the water is unlikely. However, if a contaminant somehow crosses the RO filter, it is removed from the water by this process. Moreover, if any odour is left in the water, it will also be removed at this step.

Now the water coming out of the post-carbon filter is entirely purified and suitable for drinking.

It should be noted that modern RO water purifiers are not limited to just pre-filter, carbon filter and RO membrane. But other technologies like UV and UF are also included at the same time so that your water is entirely safe.

In India, brands like Kent, Eureka Forbes, Pureit and Havells now produce advanced RO water purifiers. These are efficient and budget-friendly at the same time. You should choose an RO purifier that is efficient, budget-friendly and easy to use.

UV (Ultraviolet) water purification

UV (Ultraviolet) purification is an effective method that kills germs present in the water by ultraviolet radiation. In this case, an ultraviolet bulb is used that produces ultraviolet rays. And when passing through this ray, almost all the bacteria and viruses present in the water die.

Like the RO purification system, UV water filters also require electricity to function. It should be noted here that the process is entirely chemical-free.

UV purification process

UV purification process

Ultraviolet purification is a powerful and highly effective method of disinfecting bacteria and viruses from water.

In this technology, powerful ultraviolet rays are produced using a UV bulb. And water is passed through the ultraviolet rays. As a result, when the germs present in the water come in contact with UV rays, it attacks the genetic core of those germs (DNA) and kills them. This process can destroy up to 99.99% of the pathogens present in the water.

It is important to note here that ultraviolet radiation is a very effective method for destroying germs that cause waterborne diseases. But this technology has a significant limitation. It cannot remove soluble harmful substances like pesticides, lead, arsenic, fluoride from the water. Also, with this method, it is not possible to clean the dirty water.

Advantages and disadvantages of UV water purification

Advantages
  • UV water purifier kills 99.99% of harmful bacteria and viruses.
  • It does not use any chemicals.
  • Low maintenance costs.
  • Less costly as compared to RO water purifiers.
Disadvantages
  • Can not remove dissolved harmful substances like lead, arsenic, fluoride from the water.
  • Not capable of purifying dirty or muddy water.
  • Need electricity to work.

UF (Ultra-filtration) water purification

UF (ultra-filtration) technology is an effective water purification method that can remove harmful microorganisms from water. It is also capable of purifying mud and dirty water.

The advantage of this method is that it does not require electricity to work. And no chemicals are used in this case. In this method, water can be purified at a very low cost. That is why it is a widely used method of water purification.

But even with so many benefits, this technology has a significant disadvantage. This method cannot remove dissolved harmful substances like pesticides, lead, fluoride and arsenic from water.

UF purification process

UF purification process

Like the RO purifier, the UF water purifier also uses a membrane to remove contaminants from the water. The sheet contains numerous tiny pores that are 0.01 microns in size.

When the water is passed through this fibre membrane, these 0.01 micron-sized pores allow water molecules to pass through. But germs and dirt present in the water cannot pass through these tiny holes. So these are filtered out of water.

You are right, and this method is exactly like the RO purification procedure. But there is a difference between these two approaches. In the case of UF filter, the size of holes is larger than the RO membrane pores. So even though it removes germs or dirt from water, it can not eliminate soluble chemicals such as pesticides, arsenic, lead, etc. These toxins can easily pass through these pores.

Advantages and disadvantages of UF water purification

Advantages
  • Can work without electricity.
  • It removes harmful germs from the water.
  • Capable of purifying mud and turbid water.
  • Less costly as compared to others.
Disadvantages
  • Can not remove dissolved harmful solids like lead, arsenic, fluoride from the water.

Understand the quality of the water in your locality

Quality of the water

One of the most critical factors you should consider is the quality of the water in your locality.
There are mainly two types of water Soft water and Hard water. Generally, Water comes from a lake or river is soft water. On the other hand, underground water is hard water. Underground water contains a high amount of total dissolved solids (TDS).

Follow the points below to understand the situation and the right solution to the problem.

  • If you get hard water at your home, in other words when the TDS value is above 500mg/little, then you should go for RO water purifier.
  • When the water is soft, particularly, when the TDS value is less than 500mg/little, then you don’t need RO water purifier. Because in that situation UV water purifier is sufficient to do the job efficiently.
  • But if the Water is highly infected and the TDS value is also high, then you should consider RO+UV water purifier.

What type of water purifier is ideal for you?

At this point, you have a clear idea about different types of water purification technology, the fundamental difference between different kinds of water purifiers and various types of impurities in drinking water.

Now the question is, what type of water purifier is ideal for your home?

1. First of all, you should conduct a TDS test of the water at your home.

Please note that individual dissolved substance is also important than the total value of TDS. For instance, you may find TDS value below 300, but that water may contain a high amount of arsenic, lead or mercury.

Let’s have a look at the table below to understand the impurities and the ideal water purifier for that situation.

2. If there is any industry nearby, you should also perform a chemical test of the water to know the level of chemical impurities.

3. If you have any confusion, you should always select the best water purifiers with RO+ UV+UF.

 

Storage capacity of water purifier

What type of water purifier is ideal for you

Storage capacity is also a crucial factor to consider. Especially when you are living in a city with frequent power cuts, then big storage capacity will come in handy.

During an extended power cut, large storage capacity will make sure of continuous purified water supply.

Water purifier brand

You should consider a brand which has an excellent reputation for producing quality water purifiers. Consider choosing a brand which is trusted for providing efficient water purifiers.

Budget

You should also consider your budget for water purifier. The price and maintenance costs both will be high if you want to use a water purifier with all the features and facilities. But keep in mind that it is not necessary to have every feature. First of all, you should think about your requirements and select a model based on that. That will help you to lower the overall costs.

However, now in India, several top brands offer models with all kinds of advanced features in affordable price and low maintenance costs.

After-sales service

After-sales service is another essential factor to consider. When you face any technical difficulties in the product, poor after-sales service will cause a lot of problems.

In India, excellent after-sales service depends on location and brand. As an example, when one particular brand has inadequate after-sales services in one place. At the same time, another brand provides excellent after-sales service for that specific area.
Therefore you should select a brand which offers good quality after-sales services in your locality.

2. What is the cost of annual maintenance (AMC) of RO water purifier?

Now, almost all top water purifier brands in India offer annual maintenance service. The cost depends on the brand and the type of model.

Generally, in India, water purifier AMC providers charge between Rs. 3000 to Rs.6000 per annum, which includes periodic replacement of RO membrane, UV and UF filters, activated carbon filters, sediment filters etc.

3. What is TDS controller?

TDS controller regulates the total dissolved solids of the output water of RO water purifier. Generally, RO water purifier lowers 90% TDS of input water. For instance, if input water has a TDS value of 900, then TDS value of the purified output water will be 90.

Firstly, water with very lower TDS value doesn’t taste good. Secondly, it essential to have some minerals and salts in drinking water for your health.

Working principle of TDS controller is straightforward. It divides the input water flow into two parts, one part goes through the RO membrane, and another part goes directly through UF and UV chamber. Hence, the TDS value of the second part remains unchanged. And finally, these two types of water mixed up and come out as output water. As a result, output water contents acceptable TDS value. That is the job of a TDS controller.
