What type of accreditation must filters and chlorinators possess?

Filters and chlorinators must possess ANSI accreditation because the American National Standards Institute (ANSI) establishes the standards for equipment used in swimming pools. ANSI accreditation ensures that these products meet strict safety and quality criteria, which is crucial in maintaining water quality and safety for swimmers. This accreditation process includes rigorous testing and evaluation to determine if products comply with health and environmental standards, ensuring they are safe and effective for use in pool maintenance. The importance of this accreditation lies in its role in promoting confidence among pool operators and users regarding the reliability and performance of the equipment they use for chlorination and filtration.
