Best Water Purifiers Under ₹10,000 in India (May 2026) — What Actually Makes Water Safe to Drink

First, Understand What's Actually in Your Tap Water

The choice between RO, UV, and UF water purifiers isn't about brand preference — it's about your specific water source. If your municipal supply uses borewell water (common across Delhi-NCR, Rajasthan, Gujarat, and parts of Maharashtra), the TDS (Total Dissolved Solids) level is often 300–800 ppm or higher. At those levels, you need RO filtration, which physically removes dissolved salts and heavy metals through a semi-permeable membrane. No UV filter, no matter how powerful, removes TDS.

If you're on a municipal corporation supply with TDS below 200 ppm (typical in Chennai, Kolkata, parts of Mumbai), UV purification is sufficient. It kills bacteria and viruses using ultraviolet light. The water remains minerally balanced, which is arguably better for you — RO removes beneficial minerals like calcium and magnesium along with contaminants.

The mistake most people make is buying an RO purifier because it sounds more high-tech, when their water doesn't actually need it. Before you buy anything, get your tap water tested. Many municipal corporations offer free testing. Alternatively, a basic TDS meter costs under ₹300 on Amazon.
