RO vs UV Water Filter: Which Water Purifier Is Correct For You

There are uncountable health benefits to consuming hygienic water and staying hydrated. At least 8 glasses of water must be consumed every day to maintain a healthy lifestyle. Tap water is no longer a dependable water supply due to the widespread contamination of water sources. People frequently fall ill after drinking tap water that hasn't been filtered.


Therefore, every household must have a high-quality water purifier at home. However, the market has a variety of water purifiers that employ various methods of water filtration. Choosing the appropriate water filter for your home might therefore be confusing. Unwanted chemical compounds, organic and inorganic elements, and biological pollutants are removed from water through the help of a water purifier. 


The best devices for eliminating impurities from the water are water purifiers. You must realise,  that there are various kinds of water purifiers, and they all function differently. The two most common types of water purifiers are reverse osmosis (RO) and ultraviolet (UV).

There is always a debate going on - RO vs UV water purifier  which one is the best? Before getting into this comparison, let’s understand how these two filtration systems work. 

RO Water Purification System


RO or Reverse Osmosis is the most commonly used filtration system across the world.

This is a system for purifying water that passes water molecules via a semi-permeable membrane. Thus, dissolved salts and other contaminants are left behind as only water molecules may cross the membrane. As a result, dangerous bacteria and dissolved pollutants are eliminated from RO-filtered water. 


The reverse osmosis technique is scientific. It ensures that any dangerous dissolved salts are completely removed from the water. 


In reverse osmosis, pollutants and impurities are removed from water by forcing it through a semi-permeable substance. The best method for getting rid of germs, viruses, and other hazardous microorganisms is this one. Due to the small size of the RO membranes, even dissolved salts can be extracted.

Cons: The majority of the water that passes through a regular RO water filtration system is lost. In a home RO system, more than 80% of the water is rejected or wasted, leaving only 20% or less for consumption.

Here are some points on RO UV water purifier advantages and disadvantages:


  • When we compare UF and UV, UV is the more cost-effective option. Even if the electric current is weak, the UV light will work. This is not possible with a RO purifier. 
  • A RO water filter uses more power than a UV water purifier. When comparing RO and UV water purifiers, however, the RO water purifier is more scientific.
  • Whatever germs are eliminated inside a UV water purifier are not treated further. This means, dead bacteria still remain dissolved in water. This is not the case with a RO water purifier. 
  • The membrane within ensures that water stays on one side and everything else stays on the other. These are the advantages and disadvantages of RO vs UV.
  • When comparing RO and UV water purifiers, RO is more effective in removing such contaminants, even against UF. The dissolved solutes and salts can be extracted thanks to the high hydrostatic pressure.
  •  RO machines necessitate periodic maintenance. You can do so by contacting the maker of your cleaner. You cannot, however, maintain these gadgets yourself.

UV Water Purification System


UV water purifier system is one of the most popular techniques for disinfecting water right now, ultraviolet water purification ensures that the water is safe to drink and enhances its flavour and odour. Drinking unpurified water might leave bacteria and other organisms that reproduce in your digestive tract.


Under this filtration process, purification is done by applying effective UV (Ultraviolet) rays to  kill harmful microorganisms from the water that cause safety hazards. Consequently, all pathogens have been removed from the water. Since the UV water filter removes all harmful germs from the water  it is good for your health.

Pros: The main and major advantage of having a UV water purifier is, it is cost-effective. Since ultraviolet rays don't require any chemicals, the flavour and odour of the water are preserved. Any bacteria and viruses are removed by ultraviolet radiation, greatly enhancing the flavour.

Cons: One of the major disadvantages of UV purifiers is that most of them do not allow for the installation of a water storage tank. There is typically no choice but to fill the water into an external water bottle or container. 


UV water purifiers required a constant supply of electricity which can backfire in times of emergencies like long powercuts or electricity failures. 


Ultraviolet purifiers cannot physically eliminate germs and other microbes from the water like RO filters can. A regular UV water purifier is not favourable for treating hard water which can be considered as some of the UV water purifier side effects. 

UF Water Purification System


Now, there is another water purification method running among the industries- UF (Ultrafiltration). This is a non-electric method of purification. That means, unlike RO or UV this technology doesn’t require electricity to function. It removes molecules, bigger particles, and suspended solids from water through a hollow membrane. 

Cons: However, dissolved solids cannot be removed by UF water purifiers, which can only kill and eradicate bacteria and other germs. It cannot change hard water into soft water, unlike the RO water filter, which is considered to be a UF water purifier disadvantage.

RO vs UV vs UF water purifiers- Which one is the best?


RO (Reverse Osmosis) is more advantageous than both UV and UF. RO water is safer to drink


UV cannot eliminate dissolved contaminants in water, however, RO can. Unlike UV, RO purification removes dead microbes from the water after they have been killed. Not only that, but RO water enhances water taste and works well with high TDS levels.


Because it can operate without electricity, UF is more cost-effective. RO and UV purifiers cannot function without power. The majority of the beneficial minerals in the water are retained by UV.


The major benefit of adopting a UF purifier is that it does not require electricity. This makes it a more cost-effective solution than RO. Furthermore, because RO purifiers cannot function without electricity, UF purifiers are best suited for areas with frequent power outages.


RO water purifiers are ideal for hard water or areas with high TDS levels. UV water purifiers are suitable for purifying municipal or tap water with low TDS levels.

Furthermore, the RO water purifier aids in the removal of heavy metals and pollutants, whereas the UV water purifier is incapable of doing so.


The water purifier should be chosen based on the hardness, TDS, and PH level of the water.

For the most significant drinking experience, it is advisable to utilise a combination of RO UV UF Water Purifier, especially if you are unsure of the TDS Levels in the water in your locality.
