Best Water Purifier Buying Guide

Do you know what is the major factor for ascertaining life on any planet?

What is the thing for which ISRO has been hustling to determine life possible on the planet Mars? Yes, you got it right. The answer to both the questions is Water.

Water is an essential factor in life as much as air. Anyone can imagine life without water on any planet. We are blessed to have sufficient water on Earth for our living.

Sources of Water Pollution

Rivers are fresh, clean and unsoiled when they first flow down from melting peaks of the mountain. On their way, they accumulate salts and minerals from soiled rocks and sand.

These soiled rocks and sand consist of TDS (totally dissolved solids). TDS is full of minerals like sodium, potassium, magnesium, and chlorine also the goodness of nitrates and phosphates.

With every advantage comes a disadvantage, these natural salts even contaminate the water. Not only this, but human activities also contribute to making the water impure.

Human Activities, which pollute the water and make it impure by dumping the industrial waste in water, sewages, releasing dangerous industrial chemicals like lead, iron, arsenic, and mercury.

Water Consumption is a basic need for any living organism. One must make sure that drinking water must be pure. Drinking contaminated water can cause you many water-borne diseases like dysentery, cholera, etc.

The basic function for which a water purifier exists is to purify water & make it free from contaminants and purify the levels of impurities and TDS in water. Each filter performs a different function to come over various contamination from the water. Now, we shall discuss various types of impurities in drinking water.

Types of Impurities in Drinking Water

Now, you must be clear that water contains large quantities of salts, which is because of human and natural activities. In the same manner, even groundwater contains a lot of minerals & contaminated salts.

As we go in the coastal areas, contaminated salts increases in the groundwater. In the areas where rivers cant reach, bore wells, dug wells & tube wells are the final options for people living in them.

Water fetched through wells even requires purification because of the presence of a high level of TDS in the form of animal and plants matter. As discussed earlier, TDS contains purities like minerals and impurities like dust particles.

In cities and towns, various organizations like municipalities use chlorine to disinfect water. The usage of chlorine in high amounts can cause diseases to consumers.

Whichever water purifier you use, one thing must be ensured that the particular water purifier must eliminate the impurities and contaminants from the water before final consumption.

To get rid of these contaminants and impurities, advanced technologies like ultrafiltration methods(UVF), Reverse Osmosis(RO), ultraviolet purification(UV) must be used.

All the water purifiers that are listed above under the category of Best Water Purifier in India either uses any one of these technologies or work on all these technologies.

The Acceptable TDS Levels

Above we have already discussed the concept of TDS in water. You all might be well aware that the body requires certain minerals and salts to maintain a healthy life. Few of these essential salts come from TDS.

So, one should make sure that all the necessary minerals and salts do not get washed away during the process of purification. TDS is justified in a certain numerical range. The question that might have hit your mind by now is what the TDS range is good & what is not.

Now let us learn about acceptable TDS levels.

  • In the range 0 to 300 – Very Good
  • The range between 300 to 600 – Good
  • Between 600 to 900 – Acceptable
  • Above 900 and below 1200 – Unhealthy
  • 1200 or Above – Unacceptable 

 The figures bulleted above are indicative. However, in the case of groundwater and few other water sources TDS values varies than normal values. It usually goes under 900.

Considering the given values, you might think that the water is safe for direct consumption. But unfortunately, we advise you to avoid it.

You might come over a situation when the TDS level in the water would range from 0 to 300 which makes the water fit for drinking. In spite of good figures, water may contain a high amount of arsenic or mercury, which does not make it healthy for drinking.

To discard these kinds of impurities from the water, you need the Best Water Purifier in India.

Water Purification Technology Explaination

TDS Controller
Water that comes from an RO machine is clean, Hygenic & healthy. The RO filter removes the major part of TDS from the water. As per research, RO removes a little over 90% of the TDS. Due to this, the healthy salts like magnesium, calcium, potassium are even washed out of the water.

The TDS Controller is the mechanism that solves this trouble. This controller divides the input water into dual segments, A and B. Water in part A flows to the RO membrane. On the other hand, water in part B goes to the UV filtration that has the potential of eliminating Microorganism but not the TDS.

Then TDS Controller particularly combines this water along with RO water which improves the Ph value & the TDS level.

Pre-Activated Carbon Filter
This filter is capable of eliminating organic and other volatile compounds which is the reason for the poor smell of water. Most of the water purifiers mentioned above use this filter inside them.
Reverse Osmosis Mechanism
The next comes RO filtration. Practically, The water does not flow from higher concentration to lower concentration while flowing from the semipermeable membrane.

Thus, the water requires a push that is given by a pump. This process is called Reverse Osmosis.

The RO membrane has the ability to eliminate all the kinds of contaminants from the water. These contaminants can be lead, bacteria, mercury, viruses, and even microorganisms.

After this, water gets bifurcated into the pure water that goes to the UV Filtration and the clean water dispenses out to the drain.

Ultrafiltration
In this phase, the water goes through the ultrafiltration membrane to eliminate the final remains of contaminants with the help of the smallest pores present in the membrane. This phase usually gets an escape from the RO process.
The Post-activated Carbon filter
This filter is one of the most essential filters in water purifies. It kicks out the bad odor & smell from the water. Not only this, but it is even responsible for getting you a better water taste.
The Sediment Filter
The usage of this filter is not mandatory. You can remove it as per your will. This filter is connected outside the water purifier. It ensures that no larger impurities and contaminants are present in water.

Due to this filter, you can experience improvement in the machine’s life. This filter kicks out the thick impure particles & does not let it enter the machine which improves the life of the RO membrane.

It is advisable not to use this when the source of water is hygienic.

The Mineralizer
Mineralizer releases minerals that help in restoring minerals in the water which may have got eliminated during the process.
Ultraviolet Protection
Clean water coming out from a water purifier consists of few impurities like bacteria and viruses. This is because purifiers are not capable of eliminating impurities having a molecular weight below 20 Daltons.

**Note – Daltons is the unit that used to measure molecule weight.

Thus, these days water purifiers use ultraviolet protection technology that allows passing water through a chamber that can get you rid of ultraviolet radiation.

Most of the brands usually charge ₹ 4000 for AMC. We advise you to consult an AMC provider to know the exact price depending on your water purifier.

2. How much quantity of water is wasted by water purifiers?

One of the major limitations of water purifiers, which you cannot ignore is that the water purifiers waste a lot of water. Most of the water purifiers dispense around 650 ml of water for every 1 liter of purified water.

There is a direct relationship between TDS and water wastage. More the amount of TDS in the water, more water gets wasted. Less the amount of TDS in water, less water will be wasted.

3. What are the TDS controllers?

The meaning of TDS controllers goes by its name. A mechanism in the water purifier that can adjust the level of TDS present in the water source to make it fit for drinking purposes.

4. What do TDS Controllers/Moderators do?

RO Purifiers decrease the hardness of the water by 90%. The TDS level of the water source is around 800, the TDS level of the output water, which is feasible for drinking should be around 80. The gap between 800 to 80 is filled with a water purifier.

The water with a low TDS level does not have a pleasant taste. It is essential to have some important salts like minerals and calcium in your drinking water. The TDS machine operates in the same manner. 

The device separates the water input into 2 parts, one that goes into the RO through the membrane and other that is filtered through UV and UF. The water that is filtered by UV & UF does not have an impact on the TDS. So, the final water output is a blend of these 2 types of water.

9. What function does a mineralizer perform in a Water Purifier?

Everybody knows that an RO is capable of removing all the toxicants present in water. Without RO, toxic water can hamper the health of humans, if consumed. But RO not only kills the toxic but even kicks out essential nutrients present in the water.

Elimination of these essential nutrients makes the cleansed water less nutritious. Thus, now RO’s have an additional filtration function, which adds back the lost nutrients in the purified water making it suitable to consumption.

This additional step also helps in sustaining the pH balance of purified water. The name of this filter varies from brand to brand. For example – Aquaguard has named its filter as ‘mineral guard’ that works on the same technology.

10. Which is better among ABS plastic & stainless steel tank?

The water tanks in the water purifier are the main part of the product. As the tank can hold the capacity of at least 8 liters which can go up to any random figure as per the product you choose. So, the tank material has to be of solid and premium quality.

Therefore, very durable and hard material must be installed to handle the weight of both the water and the machine.

ABS is a kind of thermoplastic polymer that doesn’t face any issue in facing temperature fluctuations. It is a kind of eco-friendly material that is recyclable and not like the thermoset plastics this is also non-toxic and that is why these are best suited for making the water storage tanks.
