5 Things to Know Before Buying a Water Purifier

Essential tips to help you make the right choice for clean and safe drinking water.

1. Know Your Water Source

Your water source (municipal, borewell, tanker) determines the purification technology required.

2. Purification Technology

RO is ideal for high TDS water, UV kills bacteria, and UF is good for removing turbidity. Choose based on your supply.

3. Storage Capacity

Pick 7–8L capacity for small families, and 10L+ for larger households with higher water needs.

4. Maintenance & Filter Cost

Factor in annual maintenance costs and filter replacement frequency before purchasing.

5. Certifications

Look for ISI, NSF or similar certifications to ensure safety and efficiency of your purifier.
