Introduction

When choosing a water purifier, terms like UF and UV can be confusing. Here’s a quick breakdown of both, and when to use them.

1. What is UF (Ultra Filtration)?
   • Uses a hollow membrane to remove bacteria, cysts, and particles.
   • Works without electricity.
   • Cannot remove dissolved salts or viruses.
2. What is UV (Ultra Violet)?
   • Uses UV light to kill bacteria and viruses.
   • Needs electricity to operate.
   • Doesn’t remove particles or sediments—just disinfects.
3. Key Differences
   

   Feature	UF Filter	UV Filter
   Electricity needed	❌ No	✅ Yes
   Removes bacteria	✅ Yes	✅ Yes
   Kills viruses	❌ No	✅ Yes
   Removes salts	❌ No	❌ No
   Removes sediments	✅ Yes	❌ No

4. Which One Should You Choose?
   • For low TDS, clear water → UF or UV alone may be enough.
   • For contaminated water (with bacteria & viruses) → UV.
   • For hard water or high TDS → RO + UV or RO + UF combo.

Conclusion

UF and UV serve different purposes. The best choice depends on your water quality. Many modern systems include both for complete protection.
