Top 10 Best Water Purifiers in India – 2025

Best Water Purifiers are essential today, as clean drinking water plays a vital role in maintaining good health and preventing water-borne diseases. With the declining quality of tap water in many regions, installing a reliable water purifier has become a necessity rather than a luxury in modern households.

However, with so many brands, models, and purification technologies available, choosing the right purifier can be confusing for most families. That’s why in this blog, we bring you the Top 10 Best Water Purifiers in India – 2025, along with a simple explanation of the different purification technologies and guidance on how to select the best one for your home.

Whether you’re concerned about RO, UV, UF systems, or deciding if you even need a purifier based on your local water supply, this guide will help you make an informed and confident choice.

We have various technologies available for Water Purifiers in the Indian market which we have listed down below explaining each of them in brief.

RO Technology (Reverse Osmosis)

RO water purifying technology is the most commonly used for improving water for drinking and cooking and for many of us Water Purifier itself means RO. RO is a powerful technology, it can purify the most contaminated and salty water in just one go and also it can remove upto 90% of water hardness so this is a good pick if water is very hard in your area. Pore Diameter for RO Technology is 0.0001 Micron as it allows only water molecules to pass through it. Along With impurities, natural minerals are also removed and we get only transparent water. Also, the disadvantage of RO is that a lot of water gets wasted here.

NF Technology (Nanofiltration)

NF Technology is very much similar to that of RO Technology but the difference here is that the Pore Diameter of NF Technology is 0.001 Microns and because of which it removes less impurities then that of RO Technology but it retains the natural minerals of the water unlike that of RO Technology. With NF Technology, water hardness can be removed upto 60% and the advantage of this technology is that only little water is wasted in this purification method.

UF Technology (Ultrafiltration)

UF Technology filters the water without electricity while RO and NF Technology uses electricity for the purification of water. The Pore Diameter here is 0.01 Microns. Here, the water is cleaned but the natural mineral content remains unchanged but we cannot use this method if there is a problem of hard water in the area. One major advantage of this technology is that no water is wasted in this purification method.

What is UV (Ultra Violet Chambers)?

The technologies we discussed above are capable of removing solid and chemical impurities but it cannot completely remove the tiny microorganisms which is why it is recommended to have UV along-with one of the above water purifying technologies in your water purifier. This technology uses a powerful UV Rays to kill the tiny microorganisms when the water passes through the UV chamber. 

Out of all the technologies, choosing the best technology depends on the water hardness in your locality. To know the hardness of water it is important we know the TDS level of water and to determine the same we can invest in one TDS meter which is of a very nominal price but will be very helpful to us on choosing the right type of Water Purifiers for our homes.

If you want to get one TDS meter then I have mentioned the list and links of the Best TDS meters available in the market here.
