Choosing the Right Purifier: What to Consider

1. Water Quality & TDS Levels: Test your water's TDS to determine the right purification tech—RO, UV, UF, or combinations. (Romegamart)

2. Filtration Technology:

   • RO: Best for high-TDS sources (borewell, tanker)

   • UV/UF: Ideal for low-TDS municipal water

   • Multi-stage systems: Combine RO + UV/UF/Alkaline for comprehensive coverage.

3. Storage Capacity: Choose 5–7 L for smaller families, 8–12 L for larger households. (Romegamart)

4. Maintenance & Filters: Prioritize models with minimal water wastage and long-lasting filters.

5. Brand & After-Sales Service: Choose trusted brands for reliability and accessible service networks.
