Clean drinking water is a non-negotiable priority in every Indian household. With growing concerns about water contamination, Total Dissolved Solids (TDS), and harmful pollutants, investing in a reliable RO water purifier is no longer a luxury—it’s a necessity.
But with countless models available online, how do you choose the best RO for your home? We’ve made it easy for you. This 2025 guide breaks down the top RO purifiers in India, what makes them special, and where to buy them online.
Why RO Water Purifiers Are a Must-Have in India
Most Indian water sources contain a high level of:
-
TDS (Total Dissolved Solids)
-
Heavy metals like arsenic, fluoride, and lead
-
Microbiological impurities, such as bacteria and viruses
-
Industrial and agricultural contaminants
A Reverse Osmosis (RO) system filters out 95–99% of these harmful substances. It’s especially useful in cities and industrial regions where water hardness and chemical contamination are common.

What Is the Safe TDS Level for Drinking Water?
According to the World Health Organization (WHO):
-
Ideal TDS Range: 50–150 ppm
-
Upper Limit for Safety: Up to 500 ppm
Most tap water in Indian metros can have TDS levels above 600 ppm. A good RO purifier will bring this down to safe drinking levels without removing essential minerals.
