With the scarcity of fresh water becomes a major concern these days, it is very important that people prefer purchasing a water purifier to keep themselves healthy and safe. However, not too many people consider purchasing a water purifier as they lack the knowledge about the importance of water purifiers today.
Today, most of the experts have commented that the water we get is not at all safe for consumption. With our reservoirs being polluted day by day, it is necessary that everyone should consider using a water purifier.
What exactly does a water purifier does today?
A water purifier would have parts that could efficiently remove certain impurities from the water. However, a water purifier cannot purify 100% dirty water to pure water. Nevertheless, as we know, the municipal water, bore water, or pipe water is not 100% dirty and therefore, a water purifier is efficient enough to purify the water.
Here is detailed information on types of common impurities found in water and everything related to it.
|Type of impurity||Water source||Results in|
|Sand and mud||River, bore well, pipe water etc||Turbid and muddy|
|Organic compounds||Ponds and lakes||Bad odor, change in color, foul smell|
|Chlorine||Municipal water||Bitter or chlorine taste|
|Inorganic dissolved impurities like salts of sodium and potassium||Sea water, deep bore wells||Brackish or salty taste|
|Bacteria and viruses||Pipe water, water tanker filled water||Waterborne diseases|
|Inorganic dissolved impurities like magnesium and calcium||River water, lake water, bore water||Hardness and scale formation|
The quality of the water in India is evaluated based on the TDS value. TDS simply refers to Total Dissolved Salts, and its unit is ppm (Parts per Million).
In India, water with a TDS value between 150-300 ppm is considered to be safe for consumption and water with TDS above 300 or 500 ppm is considered to be contaminated water and is deemed unsafe for consumption.
After reading the above-mentioned facts you might feel like getting a water purifier, you might have already tried to get one. However, getting a water purifier is not that easy. You will have to be thorough with the factors mentioned below.
- Type of water
- Type of filtration processes required
- Storage capacity
- Price and brand
1. Type of water
This factor simply refers to the type of water to be purified. I have already provided you with the information’s about the common type of impurities that could be found in the water. All the impurities mentioned in that list could be purified using an efficient water purifier. All you have to do is first find out the TDS of your supply water and then refer the table mentioned in the section “Type of filtration processes required” PS: Calculating the TDS of water is a bit complicated process, there are several sites on the internet, which will guide you on “how to calculate the TDS of water”.
2. Type of filtration processes required
This is the most important factor that you should take into consideration while purchasing a water purifier. In the beginning, the water purifiers had simple working. However, today water purifier working is complicated and comes in different types.
- Gravity – This type of water purifiers are the simplest water purifiers available on the market today. As the name suggests, this type of water purifier utilizes the gravitational pressure that forces the water to pass through a filtration chamber or a membrane that removes the impurities from the water. Gravity water purifier is inexpensive and does not demand power supply. This type of water purifier is comparatively lesser efficient than UV and RO water purifier.
- UV – This type of water purifier uses the Ultraviolet rays to purify the water. Yes, ultraviolet rays. The water is passed through a UV chamber that disinfects impurities like bacteria and viruses, therefore, by making the water suitable for consumption.
- RO – The term RO refers to reverse osmosis, water purifiers that work on this principle forces the contaminated water to pass through a semi-permeable membrane that traps all the impurities in water. The membranes used in this process will have pores with a size almost smaller than 0.0001 microns. This, in turn, makes the RO purifier efficient enough to remove dissolved impurities with ease.
Here is a table that could help you choose the right water purifier based on the TDS value.
|TDS value||Type of water||Filter type|
|Less than 300 ppm||Clearwater||UF/gravity based filter|
|Less than 300 ppm||Muddy water with biological impurities||UF+UV filtration|
|Less than 300 ppm||Clearwater with biological impurities||UV filtration|
|Less than 300 ppm||Muddy water with no biological impurities||UF|
|More than 300 ppm||Clearwater||RO filtration|
|More than 300 ppm||Muddy water with biological impurities||RO+UV+UF|
|More than 300 ppm||Muddy water with no biological impurities||RO+UF
|More than 300||Clearwater with biological impurities||RO+UV|
3. Storage Capacity
There are different types of water purifiers that are available on the market right now. They could come up with an option to store water or without this feature. It is always recommended that you purchase a water purifier with medium water storage capacity. Water purifiers that are incorporated with UV and RO require a consistent power supply, which, simply means that the water purifier will not be functional without a power supply. This is why it is recommended that you purchase a water purifier that has a storage facility to ensure that you get uninterrupted water supply.
4. Price and brand
Water purifiers come at different price ranges, the price entirely depends on the brand and the type of filtration techniques incorporated into the product. Few of the top water purifier brands in India include Livpure, Pureit, HUL, TATA, Kent etc.
Apart from the above-mentioned factors, you should also check the water purifier size, the type of mounting, and the customer service features. Not all brands would have a customer service center in the entire locality. Therefore, before purchasing the products check if the brand has a service center at your locality as the filters have to be cleaned occasionally.
