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 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.

  1. Hello
    I got water from jet pump I.e stored water
    And having Tds 600-750 could you suggest me which purifier is better ro, ro+uv , uv
    Aquaguard company salesman came at home and told to buy for ro whereas Kent person told for ro+uv

    • Even though RO is enough for removing all the dissolved impurities and bacterium, Water Purifier companies install a UV bulb to make sure that the water is 99% free from virus, bacteria. Kent Grand Plus, Kent ACE Mineral, Aquaguard Enhance, Pureit Mineral RO + UV, Livpure Glo are the budget models. Pureit Ultima, Aquaguard Enhance, and Kent Superb are high-end models.

  2. Hi Chaitanya,
    We get Municipal Water. I would like to purchase Water Purifier for both Municipal and also Borewell. Also I want to make sure Minerals are retained. I am thinking RO+UV+TDS would be better. Kindly suggest good water purifiers at low price which is available in the market now.

    • Yes, RO + UV + TDS is required to retain natural minerals. Pureit Classic, Pureit Mineral RO UV, Kent ACE, Kent Grand Plus, Live Pep Pro+, Aquaguard Enhance are some of the best budget models that can work with all kinds of water sources like Overhead tank, borewells and tap water also.

    • The simple answer is No. UV bulb can only kill Virus, bacteria and other micro organisms. It can’t remove salts from the water.

    • The TDS levels in your water are low. You can opt for an UV + UF water purifier. Kent Maxx is one of the best UV + UF water purifiers available right now. If you get ground water or you move places frequently, It is better to opt for an RO water purifier. Kent, Pureit, Aquaguard, Livepure are some of the top brands.

  3. There are some purifies having UV and UF technology. I believe this is better and provide full feature of UF. Please confirm.

    • UV and UF combination is great for Soft water with low TDS levels. IF the water contain more TDS levels, you need an RO water purifier.

  4. So you mean uv as remains with dead bodies of micro organisms are not good for drinking, or is it????.
    As per comparision UF is btr than UV, but the UF purifier body tends to break down faster.
    UV purifier water is drinkable or not?????

    • UV water is good. But if the water contain dust particles, UV rays can not penetrate through bacterium. So, UV + UF is the good combination.

  5. I get water from Tubewel and the tds level is 360 but it does not taste salty or brackish. So what type of water purifier do I need?

  6. My tube well tds level is 360 and does not taste salty or brackish. So what type of water purifier do I need?

    • If you are sure about the TDS levels in your water, you can opt for an UV water purifier. UV + UF is good combination in case the water contains suspended particles.

      RO water purifier is suitable if you get water from bore well or any other source with more TDS levels.
