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.
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.
Best Water Purifier – Frequently Asked Questions
1. Which water purifier brand offers the best after-sales services?
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.
2. What is the annual maintenance cost (AMC) for an RO water purifier?
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
3. What are TDS Controllers / Modulators?
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.
4. What is Mineralizer / Mineral guard
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’.
5. How much water is wasted with RO water purifier?
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.
6. How do you use reject water?
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.
7. ABS Plastic or Stainless Steel tank – Which is better?
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.
8. Is it safe to buy water purifier online?
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.
9. Can I buy a non-branded RO water purifier?
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.
Final Words – Wrapping it up
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.
