Best Water Purifier – Buying Guide
What is the indicator of life on any planet?
When we say, we are exploring possibilities of life on Mars, what is it that astronomers and scientists are searching for? The answer to both the questions is ‘Water’.
Yes, water is as essential to life as air. One cannot imagine any life form without water. Fortunately, our Earth is blessed with sufficient water to take care of life in the present as well as future generations.
Sources of water pollution
The rivers are pristine when they descend from the melting snowcaps. As they find their way to the plains, these rivers gather salts and minerals from the rocks and sand.
These salts comprise of potassium, sodium, chlorine, and magnesium along with the phosphates and the nitrates. They form the major component of the totally dissolved solids (hereinafter referred to as TDS).
You will be hearing about TDS more as we go deep into this buying guide.
In addition to the natural salts, we have humans pitching in with their contributions towards polluting this pure river water.
You have human wastes like sewage and other impurities flowing into this water. Industries contribute their mite by releasing harmful industrial chemicals such as arsenic, lead, iron, and mercury.
All these impurities find their way into the human settlements thereby causing water-borne diseases like cholera, dysentery, etc. Therefore, there is an urgent need to purify the water resources before consuming them.
This is the concept behind the functioning of the various water purifiers. You have different methods of purification based on the level of impurities and TDS in water. We shall discuss each type of filter for the benefit of all.
Types of impurities in drinking water
As discussed earlier, you have various kinds of natural salts finding their way into your kitchen through the water resources. Similarly, groundwater also contains a lot of minerals and salts in its natural form.
As you move towards the coastal areas, the proportion of salt increases in the groundwater. Now, bore well and dug wells are the primary sources of water in such areas that do not have the rivers to bank upon.
This well water needs purification because it can contain other impurities like suspended plant and animal matter in addition to the TDS.
There are municipalities in towns and cities that treat such water resources with disinfectants like chlorine. Hence, you find a higher proportion of chlorine in areas served by municipalities. This is also harmful to your health.
Your water purifier needs to take care of these impurities as well. The rivers and other water resources have to contend with human, animal, and industrial wastes.
Eliminating these wastes requires the use of modern technology like Reverse Osmosis (RO), Ultraviolet purification (UV), and Ultra-filtration methods (UF). The modern water purifiers employ any or all of these methods of purification.
The acceptable TDS levels
We have seen the concept of TDS in water. We know how it manages to find its way into the water resources. In a way, our body needs some of these minerals and salts for its healthy growth.
Hence, one should ensure not to eliminate them completely from the drinking water. Now, the question arises as to what the acceptable TDS levels are.
The normal acceptable TDS levels are as follows.
- Below 300 – Considered to be excellent
- In the range 300 to 600 – Good for human consumption
- Above 600 but below 900 – Fair and acceptable
- Between 900 and 1200 – Poor levels of TDS
- Above 1200 – Unacceptable and unfit for drinking purposes
Note that these levels are purely indicative. In the normal course, you will find ground level as well as other water sources having TDS levels below 900.
As per the above table, it should be fair for consumption directly. Is it true? Unfortunately, the answer is NO. The level of concentration of individual elements of TDS is more important than the general TDS value.
It can happen that you might have water with TDS levels in the range of 300. But, the water can have a high concentration of arsenic or mercury and a lower concentration of other salts.
Under such circumstances, is the water safe? You have the answer at the tip of your tongue. This water is certainly not palatable. Hence, you need water purifiers to eliminate these impurities completely.

| 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. |
Factors to consider while buying water purifiers
You should always conduct the test of the water source at your house before deciding the type of water purifier to opt for.
1. Do the TDS evaluation test to determine the amount of TDS in water.
2. If you live in an area inhabited by industries, it is better to conduct a chemical test of the water source to determine the level of industrial pollutants.
3. If in doubt, you can always go for the best, i.e. the RO + UV + UF water filters. However, remember these filters are comparatively expensive as compared to the other water filters.
4. Your budget plays a very big role in deciding the kind of water purifier you choose. While determining the budget, you should also factor the cost of maintenance and replacement of filters.
