choosing water purifiers for indian homes

30 Jan 2020

The market for top water purifiers in India is as vast as it could be. From the metro cities to remote villages, the one need that unites all is the need for clean water for consumption. With a massive population of 1.3 billion Indians, supply of potable water, i.e. clean drinking water, is scarce. Also with a diverse geography, from deserts to seas, the quality of water received by households varies majorly. So when we see advertisements and meet sale representatives, how do we judge for ourselves what water purifier we need for our Indian homes? To make an informed choice, past the gimmicky features endorsed, it is primarily essential to study the water which needs to be filtered.

Water supplied from the municipal corporations is usually filtered out of major dissolved metals and impurities like fluoride, arsenic and lead. To take care of the pathogens dissolved, which may lead to water borne diseases, one can opt for UV filters in their water purifiers. They cannot filter out the dissolved salts from the water, but can disable the DNA of the pathogens, only killing them without removing their dead bodies from the water. This is the most efficient and natural filtration process, which eliminates no water, and doesn’t use any chemicals during the process as well.

UF water filters employ membranes to filter out water. Even though just like the UV water filters they are unable to remove the Total Dissolves Salts, i.e. TDS from the water, they can eliminate the dead bodies of the microorganisms successfully. UF filtration process doesn’t run on electricity, which RO and UV water purifier require operating. Hence for areas which face shortage of electricity, if we have access to clean water supply from municipal corporations, filters running simply on UF technology can be the most appropriate choice for water filters in such homes.

In areas along the coast where hard water runs in the supply lines, Infrared filters can come to the rescue, which use heat and light to separate negatively charged water ions, giving them a softer feel. Other forms of Ion Exchange filters similarly ionize the water molecules via the process of electrolysis. Such filtered water is lower in acidity and softer in taste, as the alkaline water is separated from the acidic.

If your home relies on bore wells, or faces shortage of clean water supply, RO filters can be a good choice for water filtration system, which can remove TDS and other harmful pathogens, unlike the UV and UF filters. RO filters use semi-permeable membranes to filter the water and obtain the desired results, but in the process can reject up to three quarters of the water-input, even if clean water supply is maintained. Such amounts of water wastage cannot be afforded by homes troubled by shortage of water. In such cases, if homes are assured of clean filtered water from municipal corporations, one can opt for UV and UF filters, or else Distillation water filters. These water purifiers use heat to evaporate the impure water, and collect the condensed water vapor, filtered out of all impurities.
