Do you need an RO water purifier?
A reverse osmosis (RO) water purifier can work extremely well, but should you invest in a pricey one when a cheaper UV purifier can get the job done just as well?
Clean, safe and pure drinking water at home is essential for your well-being. A number of purifiers are available in the market, but which one should you opt for? Every water purifier offers something different. However they all run on either reverse osmosis, ultraviolet light or filter technology. To know more about these types, go here.
An expensive reverse osmosis water purifier most certainly offers the best purification level in the market according to tests, but do you need to splurge on one if all you are looking at is basic water purification? Right Choice, an independent consumer magazine, proved in its tests that a UV purifier is enough to purify water of chemicals, residue and other contaminants. UV purifiers are usually at least Rs10,000 cheaper than RO ones and do the job well with bore-well, lake and river water which is usually supplied to most homes in India.
Why UV purifiers?
Using ultraviolet light to kill contaminants, these purifiers deliver superb results for cheap prices. In Right Choice tests, all purifiers using this technology gave great results, with the lowest score being 87%, and managed to remove almost all impurities, chemicals, bacteria and viruses from the water. The best Right Choice UV purifier costs Rs8,499 and the cheapest is tagged at a mere Rs5,999.
Ultraviolet purifiers offer great functionality and the only category in which they lag behind RO purifiers is that they don’t rectify hard water effectively. If the water you get is not extremely hard, then there is no need to opt for RO purifiers. Here are the ones which did exceptionally well in Right Choice tests:
Eureka Forbes Aquasure Crystal
The Eureka Forbes Aquasure is designed to sit on your counter or to be mounted on the wall. Containing a decalcifier, it helps stop the build-up of calcium and magnesium in water. The Aquasure also comes with a monitoring system to cut the flow of water if levels indicate the water is not safe for consumption. The purifier is also very compact, and does not take up too much space in your kitchen.

Kent UV Maxx
Kent’s UV Maxx purifier combines UV light with an ultra filtration membrane. These filters are just one step below reverse osmosis membranes and do really well in purifying water to bottled water standards. The ultra filtration pores are capable of stopping most bacteria while viruses get deactivated by the ultraviolet bulb.

Hindustan Unilver PureIt Marvella UV
The PureIt Marvella UV includes two separate sediment filters to get rid of physical dirt, an activated carbon filter to absorb odours, gases and chemicals like chlorine, plus a UV chamber to blast bacteria and viruses.
Right Choice score 89%
Eureka Forbes Aquasure Aquaflow DX
The cheapest UV purifier to qualify for the test with its high contamination removal capabilities, the Aquasure Aquaflow DX also did not perform as well when compared with others on this list. The ultraviolet light treatment is combined with an activated carbon filter and silver particles for purifying water. However, the purifier does extremely well in filtering bacteria, viruses and sediments.
