20L water jars are commonly used in homes and offices. However, not all suppliers offer the same level of quality.

1. Purification Process

Ensure the supplier follows:
• Multi-stage filtration – sand filtration, activated carbon, water softening, and micron filtration to remove suspended impurities and improve water quality
• RO treatment – reduces dissolved impurities and unwanted salts
• Controlled re-mineralisation – restores essential minerals in balanced quantities
• Ozonisation and UV disinfection – provide final microbial safety and water stability

2. Bottle Hygiene Check:

• Clean bottles
• No heavy scratches
• Proper washing process

3. Delivery Handling

Avoid suppliers who:
• Transport bottles openly
• Expose them to sunlight

4. Mineral Composition

Look for water that maintains balanced minerals, not just purified water.

5. Service Reliability

Subscription flexibility is important:
• Pause
• Resume
• Change schedule
Conclusion
A good supplier ensures quality, hygiene, and consistency.
