In this detailed guide, we break down RO, UV, UF technologies, explain TDS and pH requirements, and compare top water purifiers under ₹15,000 from Aquaguard, Pureit, Livpure, and Native by Urban Company focusing on performance, warranty, maintenance, and total cost of ownership (TCO).

Understanding RO, UV, and UF: Which One Is Right for You?
RO (Reverse Osmosis): Best for High-TDS Water
If your water source has TDS above 300 ppm, an RO purifier is essential. RO uses a semi-permeable membrane to remove dissolved salts, fluoride, arsenic, and heavy metals. It’s ideal for areas with borewell or tanker water. However, it also strips natural minerals, so choose one with a mineralizer or TDS controller.
UV (Ultraviolet): Perfect for Bacteria-Free Water
UV purification uses ultraviolet rays to kill bacteria and viruses without affecting dissolved salts. It’s great as a final purification stage in combination systems (RO+UV). UV alone doesn’t change water’s taste or TDS level but ensures it’s microbe-free.
UF (Ultrafiltration): For Low-TDS Municipal Supply
UF purifiers work without electricity and can filter turbidity, sand, and cysts, making them perfect for municipal tap water with TDS below 300 ppm. They’re maintenance-friendly and ideal for urban households with stable water quality.
TDS & pH: The Numbers That Matter
| Parameter | Recommended Range | Suitable Purifier Type |
|---|---|---|
| TDS < 300 ppm | Low | UF/UV |
| TDS 300–1000 ppm | Medium | RO + UV + Mineralizer |
| TDS > 1000 ppm | High | Advanced RO with Booster Pump |
| pH 6.5–8.5 | Safe | Use mineralizer if taste is flat |
TDS (Total Dissolved Solids) measures the concentration of minerals and salts in water. Too low a TDS (<100) results in flat-tasting water, while too high (>1000) can cause scaling and health issues. A pH range of 6.5–8.5 ensures safe and pleasant-tasting water.
Why Total Cost of Ownership (TCO) Is Crucial
Many buyers focus on MRP but ignore the recurring cost of filters, cartridges, and AMC. Over 5–8 years, this adds up significantly. A purifier that costs ₹2,000 less upfront can easily exceed others in long-term expenses.
TCO = Initial Price + Filter Replacements + AMC
