Ozone and UV Systems

Do you need testing or certification for your UV or ozone system? NSF provides both services for drinking water, municipal water, recreational water, and wastewater applications.

NSF works with public health officials, manufacturers and facility operators to evaluate products and protect human health. We develop and apply rigorous standards for ozone and ultraviolet (UV) systems across a wide range of water treatment applications.

Drinking Water:

• NSF/ANSI/CAN 60 – Drinking Water Treatment Chemicals: Health Effects.
• NSF/ANSI/CAN 61 – Drinking Water System Components: Health Effects.
• NSF/ANSI 55 – Ultraviolet Microbiological Water Treatment Systems.

Municipal Water Treatment Performance:

Public Drinking Water Equipment Performance Certification Program (PDWEP).

Recreational Water:

NSF/ANSI 50 – Equipment for Swimming Pools, Spas, Hot Tubs, and Other Recreational Water Facilities.

Wastewater:

NSF/ANSI 46 and NSF/ANSI 385 – Evaluation of Components and Devices Used in Wastewater Treatment Systems.

Partner with NSF for trusted testing and certification that ensures your UV and ozone systems meet the highest standards for safety and performance.
