Once Upon a time, Water used to be fresh, pure and Drinkable. Due to the different kinds of selfish activities done by us, we pollute Water, Air, and Food.
We can not control the air we breathe, but we can drink completely pure water. Say thanks to Water purifiers!
The Water we get from Wells, rivers and ponds contains a lot Bacteria, Virus, Cysts, inorganic elements, Dissolved Salts and Heavy Metals.
Examples of the Heavy Metals in the Water include Mercury, Leas, Cadmium, Arsenic and thallium. All of these heavy metals have five times more gravity than that of the water.

Even the Tap water we get from the Municipal Corporation contain a lot of Bacteria and other harmful elements. Drinking Pure Water is a must, and the pure water is acknowledged as the world’s first and foremost medicine.
But all these impurities can be removed by the water purifiers. In India, the three most widely used water purifiers are Reverse Osmosis Purifier, UltraViolet Water Purifier, and UltraFiltration Purifier. In this post, I am going to talk about the Ultraviolet Water Purifier and the Pros and Cons of it.
In the Previous post, i have covered about the Reverse Osmosis Water Purifiers and different types of RO Purifiers available in India.
What is a UV Water Purifier?
The Ultraviolet (UV) Purifier uses the UV Rays to kill the Bacteria, Cysts and other viruses present in the water.
But After Killing them, the Dead Bodies remain in the water. Most of the UV Water Purification systems comes with a Saftey Mechanism, and the power does not leak out when there is no water around the UV Bulb.
When the Water Flows around the UV Bulb, It kills all the Bacteria and Viruses present in the water, and you are ensured to drink the purified and safe water.
These Ultraviolet rays enter through the cells of the bacteria and viruses and destroy them thereby stopping them from reproducing in the water.
The UV Water Purifiers have a simplistic yet powerful purification process and the UV Rays kill 99.99% of the germs present in the water.
The Bulb that is located in the Water Purifier produces the Ultra Violet Light, which kills the Bacteria. A Quartz Glass sleeve is placed around the Bulb, which blocks Direct contact with the water.
The UV Water Purifier requires electricity to operate, and it uses the same amount of power that is utilized by a 40 Watt Bulb.
You can also connect your UV Water purifier to a UPS or inverter if there is a power Outage.
RO Water Purifier vs UV Water Purifier
The UV Water Purifier uses Ultraviolet rays whereas the Reverse Osmosis Purifier uses membranes to purify the water. Both of them employ a very different process to clean the water.
|RO Water Purifier||UV Water Purifier||UF Water Purifier|
|Requires Electricity to operate||Reuires Electicity to operate||No Electricity required|
|Kills and Removes all the Bacteria and Viruses from the Water.||Kills all Bacteria and Viruses but their Dead Bodies remain in the Water.||Kills and Removes all the Bacteria and Viruses from the Water.|
|Requires Electricity to Boost the Tap Water Pressure||UV Water Purifiers can work with Normal Tap Water Pressure.||UF Water Purifiers can work with Normal Tap Water Pressure.|
|Removes the Dissolved Salts||Cannot remove Dissolved Salts||Cannot remove Dissolved Salts|
|RO Purifiers has Prefiltration system to work with the Dirty Water.||Water should be clear for UV to work.||Works with Dirty Turbid Water.|
As I mentioned earlier, the UV Purifier only kills the Bacteria and cysts present in the water but their bodies remain in the water, and separate filters are required to remove them.
But In RO Purifier, All the Bacteria and Viruses are Killed and removed from the water.
The UV and UF Purifiers can not remove the Dissolved Salts present in the Water.
These Dissolved salts are harmful, and the water which contains more TDS level is not suitable for Drinking. The Reverse Osmosis purifiers can remove all the Dissolved salts present in the Water, which is not possible in the UV purifier.
If you are not sure about the TDS levels found in the Water, You can opt for the RO Water Purifier.
On the Whole, the RO Purifiers are better than the Ultraviolet Water Purifiers.
Cons of UV Water Purifier
The Ultraviolet Light inside the purifier can get blocked when scales are formed on the UV Bulb. These scales can be developed due to the excess heating of the Bulb. The UV Bulb can get ineffective after prolonged use, and you have to replace it.
Final Say: If you know the levels of TDS present in the water, you can choose the UV Water Filter. You can buy the Ultraviolet water purifier online in India at Amazon. At Amazon.in, you can read the reviews by the real customers and compare, select the Best UV Purifier that suits your needs.
