Good health is of prime importance to all. A clean and green environment, healthy and nutritious food and pure drinking water are the most essential necessities of life. Without them one cannot live a fit and healthy life, which is the absolute important requirement in today’s condition of pandemic.

There are numerous ways by which people obtain clean drinking water. Some of these are basics like by way of filtration, boiling and using impurity removers like alum and others. However, gone are the days of these primitive methods of water purification as they are not only time consuming, but do not clear all impurities effectively. The next option was non-electric water filters with purifying candles. Nonetheless, they just purified the water but did not help in making it soft in case of hard water supply or kill microorganisms to full extent. Water purifiers are mainly aimed at eliminating the micro-organisms and harmful dissolved solids present in water. It is only when the water is treated by various purification methods, does it become fit for drinking or cooking.

The current perfect solution to pure, clean and healthy drinking water is multi-utility electrically operated water purifiers. Here is a quick glance at some of the Best water purifier in India:

FREQUENTLY ASKED QUESTIONS

1. How does Reverse Osmosis (RO) work?

A.:- Reverse Osmosis is a process during which the filtered water is passed through a semi-permeable membrane. This only permits the water molecules to pass through and blocks all impurities that are large enough to pass through the small pores. Thus what comes across is pure, clean drinking water.

2. What is TDS or Total Dissolved Solids?

A: – Total dissolved solids are the various salts and minerals that are present in the water source that is to be treated. The higher concentrations of these heavy ions are harmful to health and make the water “hard”. Thus TDS controller helps to adjust the level of minerals in the purified water and makes it safe for consumption.

3. What are the different types of impurities found in water?

A: – There are two kinds of impurities that one may find in drinking water. They are suspended particles and dissolved impurities. The Suspended impurities are like dust, mud, bacteria, viruses and sand. The Dissolved impurities are soluble substances like pesticides, arsenic, and heavy metal salts like lead, mercury, copper etc.

4. What is the permissible TDS level in drinking water?

A: – According to World Health Organization, TDS level of 300 mg / liter is excellent and higher limit is 600 mg / liter. However, BIS (Bureau of Indian Standards) has set the upper limit as 500 mg/liter. Consumption of water with level over 1000 TDS causes kidney problems.

5. Why should the selection of product (purifier) be dependent on after sales service?

A: – Remember, we purchase water purifier to safe guard our health and to get clean and pure drinking water. However, constant use wears out the filters and reduces their filtration and purification capacity. Hence, it is necessary to get the machine serviced and filters replaced periodically in order to maintain good quality output. If the company is prompt in their customer response, then things move smoothly and you get a purifier in perfect condition at all times.

6. Can the RO treated rejected water be conserved?

A: – Yes, of course. Many advanced machines have the water retention provision for the rejected RO water and this can be used for other washing and cleaning purposes. If your machine does not have that tank provision, it is advisable to collect the water drained from the outlet tube in a container and use it for cleaning. After all, water is precious and we should not waste it.

SUMMARY

Pure and clean drinking water is every person’s necessity and right. It is not possible to get potable water at all locations and all the time. Nonetheless, it is essential to purify the water from which ever source is possible and render it safe and clean for drinking. 

Keeping this need in mind, many reputed companies have come up with various models of water purifiers, each using the basic UV+UF features and adding some more advanced ones like RO, TDS controller, Silver charged membrane for top level purification and many other. 

The permissible drinking water TDS level is set to 500 mg / liter by Indian standards and maximum up to 600 mg / liter by WHO (World Health Organization). Therefore, it is vital to check the TDS of the inlet water source and then select a suitable purifier that may fulfill the purifying needs. 

Since most of the purifiers are electric based, there are some models that dispense water only if there is supply. In absence of electric supply, the machine is not in a position to allow free output. In case you live in an area where power cut or fluctuation is a regular norm and if there is no provision for an inverter or generator, then the unit may be useless and you will not get access to stored water.

However, there are many models that safely dispense water even in the absence of electric supply. Such models are the best bet as per the location conditions.

CONCLUSION

As discussed throughout, water is a precious element necessary for survival and clean drinking water is of prime importance to human beings. Just as we have discussed the various purification processes, let us also understand the pros and cons of the same. The biggest advantage is of course, that all these water purifiers help in safe -guarding our health and give clean drinking water.

Nevertheless, the Reverse Osmosis process that softens the hard water by removing impurities and makes it consumable, rejects the remaining water that is left after treatment and that is drained out of the unit. With water crisis all over the world, it is not advisable to waste even a single drop. Thus, this discarded water should be properly collected in a container and used for washing, cleaning or gardening.

There are two types of models available – table top and wall mounting. Some have both the provisions and you can select the option best suited to you. The storage tank capacity also varies from model to model. From average 5 liters to 10+ liters capacity is available. It is best to select the purifier as per requirement and size of family and daily consumption.

Another most important aspect to take into consideration while finalizing the product is the company’s after sales policy and promptness. This is one product that will require immediate attention in case of breakdown, else the whole purpose of having a purifier at home will be lost and there will be requirement of purchasing outside mineral water bottles. So, do a proper research, test the water quality for hardness and then select your purifier from the whole wide range available in the market.
