Why Using A Water Purifier Is Important?
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 in danger because of excessive fluoride. Also, 10 million people are at risk due to excess arsenic in drinking water. Therefore, every Indian household should adopt a water purification system for the sake of their family’s and their own health.
Types of Water Purifiers Based on Filtration Technology
Currently, there are mainly three types of water purifiers. 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 give you an idea of how each of these technologies works and their benefits. We’ll also break down how they work, as they’re fairly complex on their own.
1. RO (Reverse Osmosis) Water Purifier
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 the 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.
Now, let’s talk about how these water purifiers work. They’re the most complex among water purifiers when it comes to how they work.
There are four stages to the RO purification process: Pre-Filter, Carbon Filter, RO Filter, and Post Carbon Filter. RO technology uses these different types of filters to purify water.
The Reverse Osmosis purification process begins with the Pre-Filter Method. This process removes large particles present in water and also reduces the Chlorine levels.
The next stage of the 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 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.
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, though, 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.

2. UV (Ultraviolet) Water Purifier
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.
Ultraviolet purification is a powerful and highly effective method of disinfecting bacteria and viruses from water. The purification process is also fairly simple.
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.

3. UF (UltraFiltration) Water Purifier
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.
Here’s how this sort of purifier filters the water;
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 the UF filter, the size of the 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.

Here’s a table comparing all three kinds of water purifiers based on the most important factors;
|RO Purifier||UV Purifier||UF Purifier|
|Kill Bacteria and Viruses|
|Remove dead bodies of Bacteria and Viruses|
|Remove dissolved Toxic Elements|

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
Water can be contaminated by various 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 India’s major problems at the moment, causing severe diseases like cancer.

What is the TDS of Water?
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, a 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.
|Less than 300||Excellent|
|300 - 500||Good - Acceptable for human consumption|
|500 - 900||Not good - Should not be consumed.|
|900 - 1200||Poor - Unfit for human consumption.|
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 a TDS value of 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 a 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.

1. Water Quality At Home
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 that 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 pick the right purifier.
2. Storage capacity
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, a large storage capacity will make sure of continuous purified water supply.
On top of that, it can also change significantly based on the size of your family. If the family has less than 4 members, you can get a purifier with a capacity of 5-8 Litres. If it has 4-6 members, then you can choose to get one with a capacity of 8-10 Litres. In case the number exceeds 6, you might likely need as much as 10 Litres worth of capacity.
Although you can go for more than what your family members need, do make that the purifier does not consume excess electricity, though.
3. Power Consumption
A standard purifier doesn’t need electricity to work, but UV and RO purifiers do, as they have a more complicated and advanced purification process. Electricity bills don’t rise significantly, but if you’re in an area with frequent power cuts, you might be better off getting a purifier that isn’t dependent on electricity.
4. Maintenance Expenses
The cost of maintenance differs across different water purifiers. Most water purifiers need servicing after every 3 to 4 months. While needing general maintenance, the filters also need changing after a period of time. Having both of these done can cost you as much as Rs 1500. Most of the best water purifiers will cost you under Rs 2000. Lower-end RO systems tend to cost much more, about Rs 2000 to Rs 4000.
5. Quality Assurance
Reading customer reviews and considering the purification technology is generally a good way to gauge the purifier’s quality. However, some high-quality water purifiers come with extra assurance. They have certifications from certain organisations that specialise in water purification or water safety. Such organisations include NSF and WQA.
6. Purification Level
Purifiers are the best way to gain access to safe drinking water. However, you need to consider a few extra things as you buy them. If you’re going for a budget water purifier, you have to consider what level of purification you need. If you live in an area where water pollution isn’t prominent, you can easily go for such a purifier. It will keep your water pure and also keep the minerals in it that are beneficial to health.
However, you’d need a more powerful water purifier, like an RO one, in an area with high levels of water pollution. If you do get one, you have to ensure that the purifier doesn’t eliminate good minerals in the water alongside the impurities.
We suggest going for a RO water purifier that comes with a mineral cartridge for the latter situation. This sort of purifier can add important minerals like Calcium and Magnesium back into the water after the filtration process is completed.
7. Advanced Purification Technologies
Sometimes the water supply can have water with TDS levels of 900ppm. In such a case, you’d need a particularly powerful water purifier. There are RO+UV+UF purifiers, which use the filtration mechanisms of all three technologies to offer maximum water purification. They are a little more expensive and have more power consumption, but they make up for that by offering bigger health benefits.
RO Water Purifiers can output excess water when filtering the water in reserve. The water that gets released isn’t drinkable, as it contains most of the impure substances that were removed from the reserved water. It is just used as a way to release unwanted substances. As the rejected water is saturated with these, it isn’t healthy to drink such water at all. You can still reuse this sort of water, though. RO Waste Water can be used to wash inorganic objects like cars, and so on.
9. Extra Safety Features
These safety features are rather uncommon in most standard water purifiers, but some of the best water purifiers come with extra features that prevent you from drinking water from them when something fails. To clarify, some purifiers come equipped with mechanisms that stop you from drinking water when the filters aren’t working properly.
For instance, some purifiers warn you sometime before the filter reaches its expiration date. Some purifiers even cut off the water supply directly if the filter gets clogged beyond what can be considered somewhat healthy.
Purifiers have their own unique design most of the time. You can get whichever fits well into the look of your kitchen. Just make sure it won’t be too large for your kitchen. You don’t need to worry much about the purifier’s weight, as you won’t move it around often.
It’s essential to keep your purifier running at peak performance; otherwise, using it would be counterproductive. Make sure you get a purifier with a good warranty, so you can get occasional maintenance done without paying extra.
It would help if you considered a brand that has an excellent reputation for producing quality water purifiers. Consider choosing a brand that is trusted for providing efficient water purifiers.
13. After-sales services
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.

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 a TDS controller?
TDS controller regulates the total dissolved solids of the output water of the RO water purifier. Generally, an RO water purifier lowers 90% TDS of input water. For instance, if input water has a TDS value of 900, then the TDS value of the purified output water will be 90.
Firstly, water with a very lower TDS value doesn’t taste good. Secondly, it essential to have some minerals and salts in drinking water for your health.
The working principle of the 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.
