Regardless of how clean your drinking water looks, there is no guarantee that it is pure and germ-free. It could have microscopic pathogens that cause diseases, new age contaminants like lead and arsenic or a very high level of TDS (Total Dissolved Salts).

Across 8 major cities in India, water- borne diseases like cholera, jaundice and typhoid accounted for 77% percent of all the diseases in India. The survey also threw light on the fact that the TDS levels are way above the permissible level in many regions in India, including cities like Mumbai, Delhi, Bangalore.

You may think that boiling your water before you drink it is good enough. However, this is far from the truth. Boiling only provides protection against microbial contamination caused by bacteria, virus, etc. it does not remove dangerous chemicals/new age contaminants like lead, pesticides and physical impurities like mud, dust, rust, etc.

So what is it that you can do to ensure that the quality of drinking water your family gets is pure and safe?

Many families are turning to water purifiers to ensure that their drinking water is safe and healthy. But, with the market flooded with a plethora of brands how do you know what water purifier to choose?

A little bit of research is all you need before you buy your water purifier. The first and foremost thing you need to know is what your water condition is. Once you know this you know what kind of water purifier you need to buy. Here’s what you need to know about the various technologies available in the market.

Reverse Osmosis

If you live in an area where you get hard water then RO water purifiers are ideal. If the TDS (Total Dissolved Salt) levels in your water exceed the permissible limit then it poses a serious threat to your health. RO water purifiers reduce the TDS content in your water to a permissible level and should be used only if the level of Total Dissolved Salts in water is very high.

RO (Reverse Osmosis) works by applying high pressure on the water depending on the level of salt content; it is then forced through a 0.0001 micron, semi-permeable membrane. RO allows cross filtration of water, where the contaminants are caught in the membrane. The impure water goes one way and the clean water goes another way. The cross filtration allows the impure water to sweep away the contaminants with it thus, preventing a build up.

Typical RO purifiers remove more than 90% of the TDS and all impurities present in the water. These impurities could range from bacteria, virus, protozoa, cysts, coliform, physical and chemical contaminants etc. hindustan unilever pureit
