What is NSF 55 certification?

NSF 55 certification is an international standard established by NSF International for ultraviolet (UV) water treatment systems. It ensures that UV sterilizers effectively reduce bacteria, viruses, and other microorganisms in drinking water.

Types of NSF 55 Certification:

🔹 Class A – Designed for disinfecting and treating microbiologically unsafe water (e.g., well water). Must provide a minimum dose of 40 mJ/cm² to effectively inactivate bacteria, viruses, and protozoa like Giardia and Cryptosporidium.

🔹 Class B – Designed for supplemental treatment of already safe water, such as municipal tap water. It helps control non-pathogenic bacteria but is not certified to disinfect unsafe water sources.

Why Is NSF 55 Important?

✅ Ensures UV systems meet strict performance and safety standards.
✅ Provides verified protection against harmful microorganisms.
✅ Helps consumers choose reliable and effective UV water sterilization systems.

If you’re looking for a UV water sterilizer, choosing an NSF 55-certified system ensures that it meets proven disinfection standards for safe drinking water. 💧🔆
