Choosing between RO purified water and bottled mineral water is a common question for Delhi families. Let us compare them on the factors that matter most.
Purity
RO Water: Removes 99.9% of bacteria, viruses, heavy metals, pesticides, and dissolved solids. TDS maintained at 80–150 ppm.
Mineral Water: Naturally filtered but may contain bacteria if storage is poor. TDS varies widely (100–500+ ppm).
Mineral Content
Both contain essential minerals, but RO water can be post-mineralized to ideal levels. Mineral water content depends on the source and cannot be controlled.
Cost Comparison
RO Water (DrowWater): ₹45 for 20 liters = just ₹2.25/liter.
Branded Mineral Water: ₹20–25 for 1 liter = 9–11x more expensive.
Environmental Impact
DrowWater reusable 20L bottles eliminate thousands of single-use plastic bottles. Much more eco-friendly than buying 1L mineral water bottles.
Verdict
For daily drinking at home and office, RO purified water at TDS 80–150 ppm is the most cost-effective, pure, and eco-friendly choice. Mineral water is good for occasional use but not practical for daily family needs.
