RO vs UV vs UF – Difference between Water Purifier Technologies

Drinking clean and pure water helps in keeping us safe and healthier. Not just that, there are many health benefits of drinking pure water. It is very important to select the right ro uv uf water purifier as there are a lot of harmful particles present in the water like artificial chemicals, pesticides, bacteria and lead. All these harmful particles are present in both good water and metropolitan water.

In this blog, we are going to compare the three major water purifier technologies, RO vs UV vs UF,  which are widely used in India. After you all are well aware of the differences between ro, uf & uv water purification technologies, you can decide which is the best water purifier to buy for you and your family.

Reverse Osmosis (RO) Water Purifier

The Reverse Osmosis (RO) purification system passes water through the pump to increase the water pressure. Then the pressured water passes through the RO membrane. During the whole process, it requires electricity to operate and helps in removing the total dissolved solids and TDS present in the water. RO purifier converts hard water to soft water. The only drawback of RO purifier is that it wastes a lot of water which cannot be consumed for drinking.

The RO water purifier also helps in pre-filtration of the water if you want to purify the unhealthy water, and will remove all the germs and viruses present in it. But to boost the pressure of the tap water, it requires electricity. It also requires a lot of water input, for instance, if you input 3 litres of water, the resultant of pure water will be only 1 litre and the other 2 litres will be impure or dirty water which cannot be consumed. However, RO rejected water can be used for several household purpose  including cleaning and mopping the house.

There are several RO water purifiers available, but a good RO system comes with a compact design, energy efficiency and easy operation. Let’s check some of the best RO purifiers available in the market:

Ultraviolet Rays (UV) Water Purifier

An Ultraviolet (UV) purification system kills contaminants, microorganisms with the help of UV radiations. The water passes through the UV radiation tube and thereby exposes water to the same. UV purifier is advisable to use with soft water which has fewer contaminants. The UV purifier requires electricity to purify, but it doesn’t need a power source to boost the water pressure as it can work with normal tap pressure.

The UV purifiers are compact designed and come with easy maintenance. It kills all the germs, viruses and bacteria present in the water but does not remove it as the dead bacteria will remain in the water only. It is a reliable, chemical-free and cost effective water purification method. It does not change the taste and colour of the water after its purification. Check below some UV water purifiers.
