Choosing Between UV and RO Water Purifier  A Complete Guide
                     Choosing Between UV and RO Water Purifier: A 
Complete Guide
Health requires water, and therefore, you must identify the appropriate water purification system 
to install in your home. As more people worry about the contamination of tap water, most 
people seek water purifier repair services to seek expert and local advice. The decision 
between UV and RO water purifiers may be puzzling to a beginner, yet to make an informed 
choice, it is essential to learn about the key distinctions between the two. In this simple and 
beginner-friendly enthusiastic blog, we have brought information about all these things, which 
include RO and UV advantages, the selection of the appropriate technology to use in a 
household, and some tips to discover safe water. Take the best decision to have the health of 
your family guaranteed using purified water that is reliable.
Water Purifiers: UV vs RO
To have safe drinking water, it is important to know how water purifiers work. RO purifiers are 
designed to eliminate dissolved contaminants of the water such as TDS, hard or brackish water, 
heavy metals and salts. UV purifiers eliminate microorganisms using the ultraviolet light and 
leave dissolved solids. Pick what's best for your water and what is true to you.
 
 
If you got water purifier issues, you may call water purifier repair services expert to keep it 
running smoothly for that continuous flow of purified water.
How UV Purifiers Work
UV purifiers are used with water or air where germicidal ultraviolet (UV-C) light is used to destroy the DNA and 
RNA of microorganisms such as bacteria, viruses and fungi.
Purifiers inactivate pathogens by damaging DNA and RNA using UV light, which is safe and effective to assure 
the disinfection of water and air with chemicals.
 
How RO Purifiers Work
RO (Reverse Osmosis) purifiers are based on the principle of applying pressure to water and forcing it through 
a semi-permeable membrane that prevents dissolved salts, heavy metals, bacteria and other contaminants to 
pass through but only permits pure water molecules to pass through and be consumed.
 
UV vs RO Water Purifiers
 
By using a semi-permeable membrane, RO purifiers dissolved solids such as heavy metals, salts and 
chemicals are eliminated but UV purifiers eliminate microorganisms such as bacteria and viruses using UV light 
without dissolved solids being removed. RO systems can be used in high-TDS water, and generates purified, 
low-TDS water where UV system can be used in low-TDS water that contains microbes
RO Purifiers (Reverse Osmosis)
 
How it works: 
High-pressure pump removes impurities of water and funnels out the dissolved impurity compounds, salts, 
heavy metal Ions and micro microbes by passing water through a semi-porous membrane.
What it gets rid of:
Total dissolved solids (TDS) such as salts, heavy metals, chemicals and organic pollutants.
Ideal for:
Needs high total dissolved solids (from 300ppm) water - Salinity, very high mineral rejection.
Pros:
Full Purification / Full Ro Membrane Removal of TDS (Total Dissolved Solids).
Cons: 
It wastes water, makes you run the water longer until it warms (not great for times of drought and if you’re not 
on an instant-hot system) and takes up more room.
For technical issues such as membrane effecting, you may search for RO repair Water Purifier services so 
that they can make it proper.
 
UV Purifiers (Ultraviolet)
 
How it works: 
It uses UV-C light to damage the DNA in micro-organisms so that they can no longer reproduce and is 
deactivated.
What it takes out: 
It kills bacteria and viruses and other tiny things but doesn't get rid of them with solids dissolved too.
Best for: 
Low TDS water with high microbial content.
Pros: 
Less water is wasted (because there’s no water pressure), less energy is used and maintenance is easier.

Cons: 
Won’t filter out dissolved solids, heavy metals or chemicals, and must be used on clear water.
Choose Between Them
For high TDS water: Opt for an RO purifier.
For low TDS water with microbial threats: Choose a UV purifier.
However if your UV purifier stops working properly you can always search for water purifier repair 
near me to find local experts who can fix the issue.
Additional Features to Consider in Water Purifiers
Beyond core purification technology consider practical features that enhance your experience.
 
 Storage Tank Material
The material of the storage tank affects water quality and purifier longevity. Stainless steel tanks 
are better than plastic, prevents bacterial growth and corrosion. They also prevent chemical 
leaching so the water remains pure. 
Filter Change Indicators
 
The modern purifiers also have filter change indicators, reminding you when the filter needs to be 
changed. These indicators monitor the amount of water or even the hours of usage in order to 
change the filter before it becomes useless. 
Before You Buy Your Water Purifier
When buying water purifier considers:
Water quality and levels,
The amount of water your household uses everyday and the purpose of storing.
Type of purifier as per your need (On high TDS RO and on microbial contamination UV),
Your budget, how much maintenance you’re willing to do on the purifier and filter lifespan,
The size of your space, level of installation convenience and aesthetic preference for a particular brand, warranty 
and after-sales support.
Whatever systems you choose don’t forget to get regular water purifier services to keep the system running 
smoothly and efficiently for long term use.
 
Conclusion:
The decision over whether to use a UV or RO water purifier lies on the quality of water. When your water 
contains a lot of TDS, salts or heavy metals go with an RO purifier and then you will get pure water. A UV purifier 
would be the best choice where the water has microbial contaminants and the water is of low TDS with important 
minerals in the water. Also, before purchasing, check storage tank material, filter change indicators and 
maintenance requirements. Knowing what your water needs will provide safe drinking water in your family. When 
in doubt, go online and type in a water purifier service near me to seek the services of the professionals in the 
area to give them the best system to install.
