RO Vs UV Vs UF Water Purifier

RO Vs UF Vs UF Water Purifier

In today’s day and age, having clean drinking water methods like UV, RO, and UF in water purification is necessary. Nowadays, dirty water would harm beyond the simply water-borne diseases. Here the real slow killers would be contaminants like lead, arsenic, and other dangerous particles, which would prove to be dangerous in the long run.

In such times, you have to invest in some of the trusted water purification systems that would remove the dangerous particles and solvents to become healthy. 

Currently, there is a longstanding debate regarding the difference between RO vs. UV vs. UF purification systems. Here you can easily select from them or the combination of the RO+UV water purifiers. There is a huge difference between RO, UV, and UF technology and even how they provide safe water consumption.

In this article, we will find out the difference between the UV, RO, and UF purifiers. We will check out how each of them works and even the difference they have in terms of the purification manner, removing germs, and maintenance. 

What Is Reverse Osmosis (RO) Water Purifier?

Called ‘Reverse Osmosis,’ the RO water purifiers are the best ones available in the market. These purifiers use the force along with the area of the concentrated water.

Now the water will flow through the semi-permeable membrane, and this will bring in pure RO water. Here the process won’t be to remove harmful particles but to eliminate the dissolved solids. The procedure is all about converting hard water into soft water and making it fit for consumption. Also, it comes with the best pre-filter, carbon filter, sediment filter, and the side stream RO membrane, among others.

Plus, it makes sure that natural minerals and nutrients are retained for providing a healthy lifestyle and even removing the harmful elements. With advanced recovery technology, in this water purification system, maximum water is retained, leading to less wastage. Also, the Reverse Osmosis method is the best method for reducing the TDS present in water.

How Does The Reverse Osmosis (RO) Purification Method Work?

The RO filtration system works by forcing the water through the special fine membrane. This helps in removing the impurities that won’t be visible to the naked eye. Also, such membranes can remove the impurities based on the shape and size. 

So, it means the particles that are larger than water molecules won’t pass through the filter. The membrane would also block harmful chemicals and contaminants like viruses, pesticides, ions, microorganisms, and bacteria, among others. The best part is that RO purification helps remove chemicals dissolved in water that other purification technologies cannot do.

What Is UV Water Purifier?

Like most of the water purifiers, the UV water purifier needs electricity for working. But it won’t need any additional power for boosting the tap water pressure. Also, it can work with normal tap pressure.

The UV water purification system helps kill the germs, bacteria, and viruses present in the water; however, the only defect is that the dead bacteria will remain in the water. Also, the UV is one of the reliable and cost-effective methods of water purification. Additionally, the UV tech is chemical-free and won’t change the taste and color of the water. To top all these features, the UV system is quite compact and easy to maintain. 

How Does The UV Water Purifier Works?

In this water purification, the UV (Ultraviolet) rays would penetrate the harmful pathogens present in your home’s water, and it will remove the illness-leading microorganism by attacking their genetic core (DNA). Also, the tool is quite effective in removing the ability of the germs to reproduce. 

You can easily disinfect your water using UV light, which is quite simple, environmentally safe, and effective. 

With the UV water purifier, you can easily destroy about 99.99% of the harmful and dangerous microorganisms, and that too without adding chemicals and even changing the water’s odor and taste. Now the UV technology runs water purification and other major forms of filtration like carbon block filters or osmosis system.

What Is UF Water Purifier?

Do you know there is a huge difference between the UV and UF technology? UF technology works without the usage of electricity. It can also easily remove all kinds of suspended solids, molecules, and large particles from the water and that through the hollow membrane. Such water purifiers can easily eliminate and kill bacteria and microorganisms, but it won’t eliminate the dissolved solids.

Frankly, unlike the RO purifiers, this cannot convert the hard water into soft water. Also, it is better to go with the RO UV water purification system having the best UF filtration for getting the best drinking experience. You can use this kind of water purification system when you are not certain about the water’s TDS levels.

How Does UF Water Purifiers Work?

Ultrafiltration is one of the membrane filtration procedures that can serve as a barrier for separating the harmful viruses, bacteria, and even various contaminants from the clean water. It is a good ultrafiltration water system that forces the water to pass through the 0.2-micron membrane. Now the suspended particles that are too large in passing through the membrane would get stuck to the outer membrane surface. So, only fresh water and dissolved minerals would easily pass through them. 

RO Vs. UV Vs. UF Water Purifiers

Features RO Water Purifier UV Water Purifier UF Water Purifier
Electricity Requires electricity for purification Needs electricity for purification Does not require electricity for purification
Filtering  Filters out all bacteria and viruses Kills all bacteria and viruses but won’t eliminate them Filters out all kinds of bacteria and viruses
High Water Pressure Needs high water pressure and uses an additional pump Works with the normal tap water pressure Works with the normal tap water pressure
Dissolved Salts Removes dissolved salts and harmful metals Cannot remove dissolved salts and harmful metals Cannot remove dissolved salts and harmful metals
Impurities Filters out all kinds of suspended impurities  Does not filter out suspended impurities Filters out all kinds of suspended and visible impurities
Size of Membrane The size of the membrane is 0.0001 Micron. No membrane present The size of the membrane is 0.0001 Micron.
TDS It removes 90% of TDS Does not remove TDS Does not remove TDS

RO Or UV Or Water Purifier, Which Is Better For You?

With the ultra-filtration procedure, you won’t need any electricity for operating. The UF membrane has higher pores as compared to the RO membrane filters. They can also handle all kinds of viruses, bacteria, and germs; however, they are ineffective in removing the TDS.

UF’s biggest advantage is that you won’t need a huge amount of maintenance, and the filters are capable of lasting for a long time. Also, these filters are not efficient in handling various heavy metals and water having high TDS levels. The UF would differ from the UV because it won’t make use of the ultraviolet radiations for removing the impurities. 


If you check out each type of water filter, even the RO and other kinds would be having negative aspects. Now the combination of the UV, RO, and UF and the TDS controller is the best one for Indian homes

So, if you are going to purchase, do deep research and then make a selection.
