We replace aggressive showroom tactics with hard data and engineering logic to find the exact purifier you need.
Precision TDS Matching
We don't recommend RO if you don't need it. We match technology (RO, UV, UF) precisely to your municipal or borewell TDS levels.
AMC Cost Forecasting
The real cost is in maintenance. See the true 5-year cost including Annual Maintenance Contracts and filter replacements before you buy.
Data-Backed Logic
Our recommendation engine uses strict engineering rules mapped against a database of the latest market purifiers.
Unbiased Catalog
We don't push specific brands. Compare Kent, Aquaguard, Livpure, and more on a perfectly level playing field.

"I almost bought a ₹20,000 RO system before taking the assessment. Turns out my municipal water only needed UV+UF. Saved me thousands in AMC costs."
— Rahul Sharma, Bangalore
The dashboard is incredible. I put in my borewell TDS of 850ppm and it instantly gave me the top 3 RO systems with the lowest 5-year maintenance cost.
Pure water, no BS.

The Ultimate Guide to Choosing a Water Purifier in India
Finding the right water purifier shouldn't feel like a gamble. With aggressive sales reps pushing expensive RO systems regardless of your actual need, homeowners often end up overpaying for machines that strip essential minerals from perfectly safe water. At Water Advisor, our mission is to cut through the marketing noise using pure data.
Why One Size Does Not Fit All
The water quality in Bangalore is drastically different from the water in Delhi or Mumbai. Even within the same city, homes relying on municipal corporation water receive vastly different quality compared to homes using borewell or tanker water. Because the source varies, the purification technology must vary as well.
RO vs. UV vs. UF: What Do They Mean?
- Reverse Osmosis (RO): The heavy-hitter. RO forces water through a microscopic membrane, removing almost everything—including healthy minerals. It is absolutely necessary for high-TDS water (above 300 ppm) to remove heavy metals and excess salts.
- Ultraviolet (UV): The bacteria killer. UV light sterilizes water by destroying the DNA of viruses and bacteria. It does not alter the taste or remove dissolved minerals, making it perfect for low-TDS municipal water.
- Ultrafiltration (UF): The physical barrier. UF uses a hollow fiber membrane to block physical impurities, mud, and cysts. It works without electricity, often used alongside UV.
The Hidden Cost: Annual Maintenance Contracts (AMC)
When buying a purifier, the upfront price tag is only half the story. Most brands make their profit on replacement filters and AMC charges. An RO membrane, pre-filters, carbon blocks, and post-carbon filters need to be changed every 6 to 12 months. An aggressively priced ₹12,000 RO system might cost you ₹25,000 over 5 years in maintenance alone. Our recommendation engine uniquely factors in these hidden costs so you know exactly what you'll spend over the lifetime of the machine.
