Water Purifier Buying Guide
Why do you need a water purifier?
You have hit the nail right on the head by asking this question. The water that is available in our taps is not exactly the best one to drink directly.
This water contains all kinds of contaminants one can imagine. It explains why many people boil water before drinking.
Boiling kills the germs, viruses, and bacteria from the water. At the same time, it kills the taste and flavour, as well but does not remove the salts from the water.
Therefore, one can resort to using water purifiers that can deliver high-quality drinking water that surprisingly, tastes good, as well.
Now the ‘Why’ part of the question is out of the way. Let us now concentrate on what to do before purchasing your water purifier.
Test the tap water
Of course, there are two ways of testing the tap water. One is to use your natural instincts, and the other is a scientific way with the use of a TDS meter or what we refer to as a water testing kit.
The natural way is to smell and taste the water. If it smells or tastes awful, you should go ahead and read the rest of the article.
At the same time, if it smells and tastes good, what should you do? You should still go ahead and read the article thoroughly.
Water that smells and tastes good is not necessarily the healthiest to drink.
Tap water in India contains soluble and insoluble impurities. Despite the municipalities purifying groundwater, the water can pick up contaminants on its way to your home.
It has to pass through pipes and tanks. Pipelines and tanks can be corroded. They can also have a mineral build-up. Both of these factors affect the quality of water.
Secondly, groundwater can have impurities like arsenic, antimony, lead, and so on. It can also contain Totally Dissolved Solids (TDS – we will be using this term frequently throughout the article).
TDS can comprise organic and inorganic salts including calcium, magnesium, potassium, chlorides, bicarbonates, and sulphates. Thus, it is good to use a TDS meter to determine the extent of TDS.
Where can you test the water?
You do not have to go to a laboratory to conduct the test. The TDS meter is a simple tool to use. It gives reasonably accurate results that should enable you to decide the type of water purifier you should have in your home.
How do you use the TDS meter?
A digital TDS meter should not cost more than a few hundred rupees. Invest in one, as it will prove useful to you for life. Here is how you use the TDS meter.
Step 1 – Determine the temperature of water in the following way
- Switch on the TDS meter and press the TEMP button.
- Place the meter inside the glass of water and note down its temperature.
- Return to the TDS mode by pressing the TEMP button again.
Step 2 – Measure the TDS level
- Remove the protective cap of the TDS meter and turn the TDS meter on.
- Immerse the TDS meter in the glass of water up to the maximum immersion level marked on the device.
- If there are any bubbles in the water, stir it gently to get rid of them.
- Wait for about 10 seconds and allow the reading to stabilise.
- Press the HOLD option and remove the device to note down the reading.
Now, you have the reading. What should you do now? This table will give you a good idea about what the reading conveys.
|TDS Level||Reasons for acceptability or Non-acceptance|
|Less than 50||Water with such a low level of TDS does not contain any essential minerals. It will be tasteless. It is not an acceptable range.|
|50 to 150||It is an acceptable level. However, if you have an RO water purifier at home, ensure that the TDS level is not below 80|
|150 to 200||This level is acceptable. Hospitals usually have this level of TDS in their water supply. It is ideal for maintaining cardiovascular fitness|
|250 to 350||Most of the Indian homes have tap water in this range. It is an acceptable range|
|350 to 500||BIS guidelines state that TDS levels up to 500 are acceptable.|
|500 to 900||As this level is not acceptable, use an RO water purifier with TDS controller/mineraliser.|
|900 to 1200||It is better to use an RO water purifier of good quality with TDS controller.|
|1200 to 2000||It is a highly unacceptable range. You will need an excellent RO water purifier that can handle water with TDS levels up to 2000.|
|Above 2000||Most of the RO water purifiers in the market cannot handle such a high level of TDS.|
We shall now look at the type of water purifier you should buy depending on the TDS level in the source water.
|TDS Level||Water Quality||Viruses/Bacteria||Ideal water purifier|
|Below 500||Good||Yes||UV water purifier should be sufficient|
|Below 500||Muddy/turbid||Yes||Go for a UV + UF water purifier|
|Above 500||Good||Yes||RO + UV water purifier with TDS controller/mineraliser should be okay|
|Above 500||Muddy/turbid||Yes||RO + UV + UF water purifier with mineraliser/TDS controller should be ideal|
|Above 2000||NA||NA||Unfit for domestic consumption|
You have done your homework correctly. Now, you know the TDS level as well as the water quality.
You should go ahead and purchase the ideal water purifier. Let us now discuss what these specific terms, TDS, UV, UF, RO, and so on signify. It will help you understand the basics well.
TDS – Totally Dissolved Solids
TDS can come in various forms. We shall now segregate our population into three distinct types
People living in villages and relying on natural sources of water
Village folk usually do not get piped water supply from municipalities. They rely on natural sources of water such as wells, borewells, rivers, and lakes.
These people use well water to cater to all requirements, domestic and agricultural.
If you venture into a village, you will find domestic animals like cows, buffaloes, goats, and dogs sharing the well water with humans. Naturally, there can be high levels of contaminants.
Secondly, industries in the vicinity of the villages dump their toxic wastes into the rivers and lakes.
The groundwater resources also get polluted due to the indiscriminate release of harmful metals like lead, arsenic, mercury, and so on. All these impurities, visible and impurities constitute TDS.
However, one should note that not all TDS is bad. The groundwater contains useful minerals like calcium, magnesium, and potassium, but the harmful TDS makes it necessary for village folk to invest in a good-quality RO water purifier and with a TDS controller.
We shall look into this aspect when we discuss RO water purification.
India has a vast coastal area with millions of people depending on salty groundwater for their consumption needs.
This water has a high level of TDS. Therefore, they should prefer the RO + UV + UV water purifier with TDS controller or mineraliser for domestic consumption.
We shall now discuss the different types of water filtering methods such as UV, UF, and RO. The concept should be clear before you decide to purchase the water purifier of your choice.
Different Types of Water Purification Systems
Gravity-based water purification systems
Old-timers will recall the simple water filter that used to be common in all households. It used to consist of two containers placed one over the other.
The top container used to have water filtering candles. One used to fill this container with the source water. The water seeps through the fine holes present in the filtering candles into the container below.
This water purification system is an example of gravity-based water purification. It is a kind of UF process. UF stands for Ultra Filtration.
The modern-day UF filters have such a membrane that can trap visible as well as ultrafine contaminants to provide water of good quality.
Such water filters are best in areas where the TDS levels are less than 500. Such water purification systems do not require any electricity for its functioning.
Ultra-Violet Chamber water purification water systems
About 30 years back, there were no RO water purifiers in India. People used to rely on the UF process for their water purification.
The turn of the twenty-first century saw the introduction of ultraviolet (UV) chambers as an effective method of water purification. UV purification is an effective method, as it can eliminate harmful viruses and bacteria.
The water passes through a UV chamber that serves its purpose by killing the germs and providing healthy water to drink.
Such water purification systems need electricity to work. Secondly, there is a disadvantage because the UV chamber can kill the germs but not destroy the bodies of the viruses and bacteria.
Of course, that should not affect your health in any way. However, it is better to pass such water through a UF membrane to remove the remnants.
Reverse Osmosis – RO water purifier
To understand Reverse Osmosis, one should be conversant with the principles of osmosis.
This requires us to go back to our school days and reopen the biology books. Osmosis is a natural process where a liquid in an area with a lower concentration tends to move towards an area of higher concentration through a semipermeable membrane.
A simple example of osmosis is when you place a potato inside a glass of water. After some time you will find the vegetable swelling up because the water from the glass seeps through inside the potato.
The potato contains a high concentration of starch. The potato skin acts as a semipermeable membrane. The significance of the semipermeable membrane is that it does not allow the reverse flow of water under normal circumstances.
Reverse osmosis is reversing the process of osmosis. In this process, water moves from an area of higher concentration to that of a lower concentration through a semipermeable membrane.
RO water purifiers work on a similar procedure where the impure water with a higher TDS level passes through a semipermeable RO membrane.
The membrane has millions of small pores through which the salts cannot pass through. The water molecules are small enough to seep through thereby ensuring the elimination of TDS.
However, this process requires the application of pressure. Hence, RO water purifiers come with built-in pumps to quicken the process.
We shall now discuss the working principle of an RO water purifier.
RO Water Purifier – Working principle
The RO water purifiers available in the market employ a six-level or seven-level water filtration process.
Comparison between different water purification systems
We have seen the different types of water purification systems in the above paragraphs. Each of these systems has its advantages and disadvantages. This comparison will highlight the difference between these systems and clear the concept.
RO vs UV vs UF
|RO Water Purifier||UV Water Purifier||UF Water Purifier|
|Requires Electricity to operate||Requires Electricity to operate||No Electricity required|
|Kills and Removes all the Bacteria and Viruses from the Water.||Kills all Bacteria and Viruses but their Dead Bodies remain in the Water.||Kills and Removes all the Bacteria and Viruses from the Water.|
|Requires Electricity to Boost the Tap Water Pressure||UV Water Purifiers can work with Normal Tap Water Pressure.||UF Water Purifiers can work with Normal Tap Water Pressure.|
|Removes the Dissolved Salts||Cannot remove Dissolved Salts||Cannot remove Dissolved Salts|
|RO Purifiers has Prefiltration system to work with the Dirty Water.||Water should be clear for UV to work.||Works with Dirty Turbid Water.|
Best Water Purifier – Frequently Asked Questions
On this era of customer service, all water purifier brands offer good after-sales services.
However, it depends on various factors such as availability of service centres in your city, accessibility to spare parts, and so on. The best way to verify these factors is to do a local search on Google or go through Just Dial reviews.
Going through the official websites or e-commerce websites where customers post their reviews is also a good way of ascertaining the after-sales service facilities of water purifier brands.
Most of the top water purifier brands offer regular AMC services. The rates depend on various factors. Usually, it is in the range of around Rs 4,000 per annum. However, it is better to verify from the water purifier AMC provider.
This AMC includes the cost of replacement of the various filters like RO membrane, UV and UF filters, activated carbon filters, and sediment filters.
You have to replace these filters on an annual basis to extract optimum performance from your water purifier. Refer to the actual specifications
As the name suggests, TDS controllers control the proportion of TDS in the water coming out of the RO water purifier. Why do you need these controllers?
The RO purifiers reduce the hardness of input water by approximately 90%. Hence, if the TDS level of the water source is around 800, the TDS proportion of the output water will be in the range of 80.
This water with a low TDS level does not have good taste. Secondly, you need some minerals and salts in the water to enhance the taste. The TDS controllers work in the following manner.
The TDS controller divides the water that goes into the RO water system into two parts. One part goes through the RO membrane whereas the other part goes into the UV and UF filters.
The water that goes through the UV and UF filters do not undergo any change in the TDS levels. Therefore you get two different outputs. The final output is a mixture of both these waters. This is the job of the TDS modulator.
One must admit that the RO water purifier does a great job of purifying the water. But, it removes essential minerals along with the hazardous ones.
This leaves the output water with a bland taste that does not have much nutrient value. Therefore, you have water purifier brands including an extra stage of filtration that ensures the addition of essential minerals to the water.
This helps in maintaining the pH balance as well. Different brands have different names for these mineralizers. Aquaguard names it ‘Mineral Guard’.
The biggest drawback of RO water purifiers is that it wastes water a lot. For every litre of pure water it produces, the machines waste 2 litres of water.
The wastage of water depends on the quality of the input water. The higher the TDS of input water, the higher is the wastage
The reject water contains 95 to 99% of impurities. Hence, this water is absolutely unfit for human consumption. However, there are other uses.
You can use this water for gardening, cleaning utensils, mopping floors, cleaning bathroom floors and toilets. However, one should note to wash the utensils with tap water to remove the salt deposits.
Storage tanks are essential ingredients in any water purifier. These storage tanks are anywhere in the capacity of 10 litres or more.
Hence, you need strong material to withstand the weight of the machine as well as the water. ABS (Acrylonitrile Butadiene Styrene) is a thermoplastic polymer capable of withstanding high-temperature fluctuations.
It is a recyclable material much unlike the thermoset plastics. They are non-toxic in nature. This makes this material perfect for manufacturing water storage tanks.
Steel is comparatively heavier to ABS plastic. Secondly, ABS plastic is non-toxic and more durable than steel. They can withstand a high-temperature range.
ABS plastic does not require as much maintenance as required by steel tanks. Hence, they are preferable to stainless steel tanks today.
It depends on the customer and the website from where he chooses to purchase. Some people are more comfortable buying water purifiers after having a look at the features. Some people are comfortable buying online.
However, one should go for reputed brands from reliable websites like Amazon. You get good deals at these websites.
It is never advisable to buy a non-branded water purifier. Your health is always more important. Invest in a reputed brand because of the quality you get.
Non-branded water purifiers do not have TDS controllers or mineralizers. This affects the quality of the output. These locally made water purifiers might be inexpensive, but they are not worth investing. You will lose all the minerals in the water when you opt to buy the cheap ones.
You have just gone through the RO water purifier buying guide. This guide should help you make an easy decision about opting for the best water purifier.
We have seen the differences between the various purification technologies and seen that a combination of all these technologies is the best option available to you.
Hence, you find the major water purifier brands manufacturing water purifiers with multi-filtration technologies. Hence, a water purifier providing RO+UV+UF+TDS Controller facilities should be the right one to go ahead.
These are the best water purifiers in India. The list will be updated on a regular basis. If you have any queries reading the selection of water purifiers, post them in the comments section below, and we will be glad to answer them.
