UV water filtration is among the rangingly popular trio of water purifiers, the other two being reverse osmosis (RO) and ultra filtration (UF). As such, there is no shortage of options when it comes to picking the best UV water purifier in India.
UV-based water purifiers leverage ultraviolet or UV rays that destroy illness-causing pathogens and microorganisms from the water supply. The primary concern with biological impurities is their ability to reproduce, which is completely eliminated by means of ultraviolet filtration. Due to the superior water filtration offered by UV purifiers, they are easily among the top options for the best water purifier in India.

Working & Buying Guide
Although standalone UV water purifiers are available, many purifiers leveraging ultraviolet filtration paired with other water purification techniques. These are usually reverse osmosis (RO) and ultrafiltration (UF). Now, let’s understand how UV water purifier works.
In order to ensure you get the best water purifier, you need to first understand how exactly a UV-based water purifier works. That is exactly what we’ll cover in this very section.
The RO membrane is incapable of filtering impurities with a molecular weight less than 20 Da. Moreover, it doesn’t eliminate monovalent ions, such as sodium. These both as well as biological impurities, like microbes and pathogens, are easily removed by ultraviolet rays.
In a UV-based water purifier, water is fed to the UV chamber. Depending on the build of the purifier, the water is directly fed to the UV chamber or first passes through additional filtering mechanisms, such as a sediment filter and/or a RO filter.
The UV chamber is where the ultraviolet radiation, by means of an UV bulb, kills all the harmful pathogens and microorganisms present in the water. Usually, an UF filter is in place to filter the remains of the dead microbes and pathogens.
The resulting water i.e. the water that comes out of the UV chamber is free from harmful bacteria and viruses. This is then given out by the filter or enters subsequent water filtration process depending on the filtration mechanism used in the UV-based water purifier.
When to use
Ultraviolet filtration is an ideal water purification technique when:
- The TDS (totally dissolved solids) content of water is less than 300 ppm, and
- The water is not muddy, and
- The content of biological impurities is significant, and
Any best UV water purifier in India is apt to be used when the mineral content is low. When it is higher, a UV+RO water purifier is the best option.

The rise in water pollution levels throughout the world has led to water purifiers becoming an essential home appliance. Now, you shall be able to pick the most suitable best UV water purifier as per your requirements and drink safe, pure water.
Frequently Asked Questions
For an operation of 40 to 50 hours, a typical UV purifier requires a single unit of electricity. Hence, it is an energy-efficient unit.
It is a product of the intensity of the UV rays and the contact time or exposure time i.e. the duration for which the microbes and pathogens are exposed to the UV light.
Usually, UV filters are paired with RO known as UV+RO filters, UF called UV+UF filters. Some filters have all the three technologies, and, hence, are called UV+RO+UF filters.
