Life without a water purifier is unthinkable! But between Reverse Osmosis and Ultraviolet technology, we tell you which one to choose, based on their pros and cons
RO (Reverse Osmosis) Water Purifier
In this form of water purification the process of osmosis causes the water molecules to pass through a semi-permeable membrane under high pressure. This method of filtration removes maximum dissolved salts, large particles, impurities and bacteria from the water and converts the hard water into soft water.
Pros
RO water is very hygienic because it is free from impurities and the water is filtered only after all the microorganisms are removed.
RO water purifiers are effective in removing heavy metals, dissolved salts and reduce the TDS value of the water.
Additionally, this water purifier filters both suspended and visible impurities and is also effective in purifying muddy water.
Cons
RO requires electricity to increase the water pressure so that the water can pass through the semi-permeable membrane.
Since these contraptions eliminate contaminated water at every stage of purification, it results in a lot of water wastage.
As per studies an RO purifier not only removes impurities but also removes essential minerals like calcium, potassium, sodium and magnesium from the water. Therefore it is advisable to go for a system with RO and Mineral fortification technology that adds back all the good minerals.
UV (Ultra Violet) Water Purifier
The water passes through a UV light source in this method. The UV light attacks the genetic core of bacteria and removes it.
Pros
UV water filters can work with normal water pressure.
It is effective in disinfecting the water by removing invisible bacteria.
Here there is no wastage of water.
There is no change in the taste of water.
Cons
The biggest drawback is that although all the bacteria is killed the dead microorganisms remain in the water.
If the water is muddy and has a high degree of sedimentation, then the UV water purifier is not effective in disinfecting the water.
The TDS value of UV purified water does not change.
