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.

Currently, various water purifier models are available in the Indian market. Choosing the best one, depending on your requirements, is tough. Before you buy a water purifier for your home, you should have some basic knowledge about water purification systems. Also, you need to understand the technical details of the product.

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 started with water, and the water nourishes life. No life is possible without water. About 70 % of the human body is made up of water. Also, water is present in all plants and animals bodies. That is why water is considered as the most essential and precious resource of the earth. The sources of the water are mainly two types, surface water and groundwater.

The water which is present above the ground is considered as surface water. The water of the ocean, rivers, lakes, streams and ponds is called surface water. Rain and melting snow on the mountain are the primary sources of surface water.

On the other hand, the water which is present beneath the ground is called groundwater. Groundwater can present in the soil and between rocks under the ground. The underground water is the primary source of water for most of the population.

Most noteworthy, only 3% of the water on earth is freshwater. There are some countries where groundwater is not accessible. They use seawater to fulfil their water requirements. Desalination is the process to remove salts and other impurities from seawater.

Causes of water pollution

Causes of water pollution

Water is crucial to our life. No one can survive without water, and water is the most precious resource of the earth. However, now water pollution is the most serious problems the world is facing.

Water pollution occurs when harmful toxic elements enter and dissolve into water sources such as rivers, lakes, oceans, and so on. Moreover, these toxic substances also seep through and enter into the groundwater. This makes the water impure, and we use that contaminated water for our daily activities, including drinking.

There are several reasons for water pollution. Most common causes are municipal sewage and industrial chemical wastes. Agricultural practices, such as using massive pesticides, also cause water pollution. Pesticides contain harmful chemicals like arsenic, lead, and mercury, which can cause serious water pollution.

All these impurities cause serious health problems. Therefore, it is essential to purify water before drinking.

Types of contamination in drinking water

Contamination of water

Water can be contaminated by different kinds of pollutants like organic, inorganic, radioactive etc. Usually, contaminations are much lower in mountain and hills areas whereas cities and rural areas have much more impurities in water.

Groundwater is the primary source for most places in India, which can be contaminated with harmful microorganisms and toxic chemicals. Before supplying municipalities disinfect water with chlorine. Hence, you get a smell of chlorine in municipal water. Excess chlorine in drinking water is also harmful to human health.

There are different kinds of water purifiers for different types of water contamination such as microorganisms contamination, harmful chemicals and impurities like mud or turbid water. Before purchasing a water purifier, always know the kind of contamination of the water at your home. If the water is highly contaminated, then you need to buy a RO+UV+UF water purifier.

What is the TDS of water?

TDS meter

TDS stands for total dissolved solids. The term TDS represents the total amount of dissolved solid substances present in the water.
These solid substances are mainly inorganic salts and a small number of organic compounds. Generally, sodium, potassium, magnesium and calcium are common inorganic salts found in water.
These salts come from both natural sources and as a result of human activities such as agriculture and urban developments.

Low TDS value causes the bad taste of the water. On the other hand, high TDS value usually indicates contamination of harmful substances such as lead, arsenic, fluoride etc.

Have a look at the points below to understand acceptable TDS value of the drinking water.

  • Below 300 – Excellent for consumption.
  • Between 300 to 600 – Good for consumption.
  • Between 600 to 900 – Considered to be poor.
  • Above 900 – Bad and unfit for drinking.

You can measure the TDS value of the water quickly by the help of a TDS meter.

Now, in India, most of the people are consuming water which contains TDS value more than 900mg/little, which is not safe.

However, remember that the acceptable values of TDS mentioned above are only indicative. If you measure the TDS value of groundwater or municipal water, you might find the value below 900. Does it mean you can consume that water directly? No, because an individual dissolved substance is more important than the overall value of TDS. You may find TDS value below 300, which is described above as excellent for consumption. But that water may contain a high amount of arsenic, lead or mercury.

Dissolved solids such as lead, arsenic, fluoride, radium, barium, cadmium are considered as slow poison and much more harmful than bacteria and viruses.

Under these circumstances, you should not drink water without purification. You can remove all these toxic substances from drinking water by installing a good RO water purifier.

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

There are mainly three types of water purification technology used in India such as RO water purification, UV water purification and UF water purification.

RO (Reverse Osmosis) water purification

Reverse Osmosis (RO) is the most advanced technology which can remove harmful impurities like chemicals, bacteria and viruses from water. Notably, it is the only technology available today, which is capable of eliminating harmful dissolved solids/ salts from water.

The first thing to remember, the RO purifiers need electricity to work.
Usually, RO purification system features pre-filtration which is capable of purifying dirty or muddy water. Although, it can not convert saline water into fresh drinking water. In other words, desalination is not possible with the help of RO purifiers.

Also, RO water purifier needs more amount of water to work, and it wastes a lot of water as compared to other purification systems.

Generally, RO water purifier wastes three litres of water to produce one little of purified water. In this case, 25% of water comes as purified and rest 75% is wastewater, which you can use for gardening or house mopping purposes.

RO purification process

Reverse Osmosis purification process has mainly four stages. It utilises different types of filters to clean the impure water.

RO Water Purification

Pre-filter or sediment filter

Reverse Osmosis purification process begins with pre-filter. That process removes large sediment present in the water and also reduces chlorine of the water.

Carbon filter

The carbon filter is the second step of the whole purification process. After pre-filtration water passes through a carbon filter which helps to remove organic compounds and odour present in the water.

RO membrane

RO membrane is the most crucial part of the whole process, which starts after the carbon Filter. RO membrane is a plastic material, which only allows water molecules to pass through and filter out harmful impurities like lead, arsenic, fluoride, radium, barium, cadmium, cyst (cryptosporidium) from the water. Moreover, the process also reduces total dissolved solids (TDS) of the water.

Post Carbon Filter

A post-carbon filter or post-filter is the last step. In this process, water again passes through a second carbon filter which helps to remove any contamination which passes the RO membrane. Further, this step removes any remaining odour of the water. And now finally the water is ready to drink.

Please note that the modern RO water purifier is not only limited to pre-filter, carbon filter and RO membrane. It also includes other technologies like UV and UF as well.

Now in India, Water purifier brands like Kent, Eureka Forbes, Tata swach etc. produce various RO water purifiers which are efficient and budget-friendly.

You should select an RO water purifier, which is energy efficient, budget-friendly and easy to use.

Advantages and disadvantages of RO water purification

Advantages
  • RO water purifier removes toxic dissolved chemicals and heavy metals from the water.
  • Disinfect water by removing bacteria, viruses present in the water.
  • The only solution to Purify hard water.
  • You don’t need to spend money on costly bottled water.
Disadvantages
  • RO water purifier removes essential minerals from the water. But, modern RO water purifier comes with TDS controller to solve the problem.
  • Costly as compared to other water purifiers.
  • Need electricity to work.

UV (Ultraviolet) water purification

In short, the Ultraviolet technology uses an ultraviolet bulb to produce ultraviolet rays which kill almost all bacteria and viruses present in the water. UV water purifier requires electricity to work, and the process is chemicals free.

UV purification process

UV purification process

Ultraviolet purification is an efficient method to disinfect bacteria and viruses from water.
In this process, water passes through ultraviolet rays. If there is any bacteria or virus present in the water, ultraviolet ray penetrates and kills it by attacking their genetic core(DNA). This process can destroy 99.99 % of harmful pathogens present in the water.

The most important thing to remember that, the UV water purifier can not remove dissolved harmful substances like lead, arsenic, fluoride from the water. Also, it can not clean 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) water purifier is capable of removing harmful microorganisms from water. It can also purify mud and dirty water. The most significant advantage of UF water purifier is that it doesn’t require electricity to work.

UF purification process

UF purification process

Like RO purifier, UF water purifier also utilises a membrane to filter out impurities from the water. But the UF membrane has bigger pores as compared to RO membrane.

As a result, the UF membrane is capable of purifying the water by removing impurities like bacteria, viruses and mud but can not remove dissolved harmful solids like lead, arsenic, fluoride from the water.

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.
