RO versus UV Water Purifiers: A Detailed Comparison

Before buying a specific item, you need to do profound and comprehensive research about the thing. And, if the thing in question is something as important as a water purifier, you need to do a lot of research as to which turns out best for you.

We have analyzed RO UV water purifier units performance in 9 distinct areas below. I’m sure this will offer you some clarity, and you will get answers to all your questions.

When to Use

A considerable quantity of the underground water sources in India is polluted by modern waste. They additionally contain high TDS, making the water unsuitable for utilization. As referenced above, the reverse osmosis framework works viably in eliminating high TDS. In doing such, it decreases the hardness of the water, making it usable for day to day use. Then again, since UV purifier units can’t change the TDS, they are not suggested for well water. But, UV purifiers can function well with lakes, streams, and surprisingly – metropolitan water supplies. 

On account of muddy water, both UV and RO purifiers will require a pre-filter. If the TDS of your water is more than 300 PPM, you can choose RO purifiers. On the other hand, if the PPM of your water is less than 300 PPM, you can go for UV purifiers. Keep in mind that RO alone can’t eliminate microorganisms. Yet, a mix of RO+UV is very effective as UV purifiers eliminate organisms autonomously. Replace you fridge water filter in time and check the ge refrigerator water filter xwf from Waterdrop.


As far as value is concerned, UV purifiers are, for the most part – more feasible. The pocket-accommodating strategy is for those on a strict financial plan and needs a water purifier that kills microorganisms.

Notwithstanding, due to a multi-scale execution, reverse osmosis frameworks are twice costlier than UV channels. Besides, the RO frameworks commonly comprise five to six phases of decontamination. The additional channels mean more upkeep costs, too.


Upkeep is a big piece of the interaction when we talk about sanitizing frameworks. A few electrical parts require mandatory maintenance to guarantee better execution. Besides, because of the contaminated climate in India, dust saturates the channels blocking their exhibition.

Also, most UV channels require UV-light substitutions that can be expensive. Be that as it may, this support isn’t standard, making it moderately less expensive. Reverse Osmosis, interestingly, needs cartridge and film changes which can be weighty on the pocket. Albeit both the purifiers require customary support, RO purifiers’ upkeep cost is on the higher side.

Energy Consumption

Both UV and RO purifiers work on power. Most RO purifiers accompany an energy-saving component that stops the framework when not being used. It is likewise significant to take note that RO purifiers demand energy to support water pressure. This lift is fundamental for pushing water through the film to sift through toxins. UV purifiers – works with standard regular water pressure, decreasing the requirement for power.


The two frameworks likewise change depending on the execution. The UV channels target microscopic organisms and infections, killing them simultaneously. Be that as it may, RO channels work on a few issues simultaneously. In addition, they reduce the TDS. However, they likewise examine through dead microorganism bodies. The actuated carbon channels in RO frameworks improve the taste, making it better for the purchaser.

A contrast between UV and RO is that UV light kills microorganisms. RO film filters through these dead microorganisms. Remember, RO can’t kill these microorganisms like the UV channels.

Time to Purify

Time matters – in any event, you can hardly wait for quite a long time to get the water refined. Along these lines, this is something you should investigate if your home requires a ton of water each day. Because of the distinction in phases of refinement, UV channels convey water in considerably less time.

Reverse Osmosis moves water through a few phases, each taking as much time as is needed to clear the water.

Water Wastage

The UV channel doesn’t need extra water, which implies there is zero water wastage. Be that as it may, Reverse Osmosis uses more water, hence, more wasted water. Because of a significant degree of TDS in this water, it becomes undrinkable.

Most purifiers waste around 650ml of water for each 1 litre of clean water. This sum can be filled into an oddball tank and reused for family tasks like washing and cleaning.


Commonly, UV purifiers don’t have a capacity tank. That implies you need to fill pots or containers of water physically each time. RO frameworks ordinarily comprise a capacity tank with a limit of five to fifteen litres relying upon the model. It offers adequate room to store cleaned water for the afternoon. With this, you won’t need to utilize the framework much of the time, saving power all the while.
