Difference between RO, UV and UF Water Purifiers

ro-vs-uv-vs-uf-Difference

When it comes to deciding the best solution to have clean water in your home, the only viable solution that comes to our mind is a handy kitchen appliance called water purifier. Hence, we need to be utmost careful while choosing the best water purifier.

While we have to look into factors like power consumption, size, usability etc. It is very important that we understand the difference between RO and UV purifying technologies.

In this article, we will cover all the aspects if RO, UV and UF technologies and then you can find a table below which shows the difference between RO, UV and UF Water purifiers.

RO vs UV, Which one has an Upper Hand?

RO stands for Reverse Osmosis and has several layers (steps) of purification. As the type of water being delivered to your home depends on the location you are from, RO is suitable when the water you receive has more minerals. Moreover, it has an inbuilt system of taking out TDS (Total Dissolved Salts) out of the water and provides clean drinking water.

The RO water purifier works on reverse osmosis phenomenon and takes water from higher concentration to lower concentration while continuously taking out TDS and various minerals. This ensures that the water has the right mix of minerals and is free from dissolved salts.

The working principle is simple, the water is made to pass through a membrane which traps all the bacteria. However, this doesn’t ensure complete removal of bacteria.

Coming to UV water purifiers, it basically kills bacteria, viruses and unwanted minerals by using strong UV rays, because of the intensity of UV rays there is complete filtration of all unwanted things. This ensures that water is 100% pure and keeps all water-borne diseases at bay.

These aspects has made UV water purifiers popular in the market. This can also work with other technologies like RO. Hence, you can find many RO+UV water purifiers. This will ensure that the water you are drinking is 100% free from contaminants and is mineral rich.

Considering all the above factors, RO water purifiers have some positives like lower power consumption and lesser purification time. However, the sole purpose of having a water purifier is clean water which is where we feel that UV has an upper hand.

For the best results, it would ideal for you to buy a RO+UV water purifier even though you have to pay a few thousand extra. It is better to spend here than pour money into hospital bills later.

Difference Between RO, UV and UF Water Purifiers

We have already discussed the difference between RO and UV technologies. Now, let us
understand the working of UF technology in water purifiers. The main difference here is that the membrane has tiny holes which provide an extra level of purification.

Added to this UF purifiers work efficiently even when the water is turbid. These purifiers come with uninstalled TDS remover which can be a concern.

RO, UV and UF systems mainly vary in their mechanism, working and deliverable. This table below gives the main differences between RO, UF & UV water purification technologies.

Who is the Winner Among the Three?

After thoroughly understanding the working of all three technologies you would have gotten an idea that each of them have unique capabilities. While RO provides decent purification and lesser power consumption, UV and UF purifiers ensure an extra level of purification.

As the prime objective here is to have clean drinking water, we suggest you to go with RO+UV+UF purifiers as they have the benefits of all three technologies in one.

Trying to save a few thousands now shouldn’t put you in a spot later, when you may have to spend in lakhs due to some disease which could have been easily avoided by consumption of pure water.

While the saying ‘Health is wealth’ is the most cliched one, there is no doubt that it still holds true in the modern society.
