NSF offers two solutions that meet your needs:

>NSF REG4 S3, which does not have any facility audit requirements but mandates a full retest after five years

NSF REG4 Certification

NSF is the world leader in standards development, product testing and certification, education and risk-management services. Our mission is to protect and improve human and planet health. Since 1957, we've certified over 100,000 products in the water distribution and treatment chemicals industries.

Since 1985, we've also been the leader in drinking water treatment unit (filtration) product certification, with over 400 companies and 12,000 products listed.

NSF has launched a state-of-the-art water testing laboratory in Rheda-Wiedenbrück, Germany, its first in continental Europe. This facility offers in-house certification testing for NSF/ANSI/CAN 60 and 61 standards, streamlining the certification process for water product manufacturers in Europe, the Middle-East, and Africa (EMEA). By eliminating the need for overseas shipping, the new lab significantly reduces time-to-market and enhances quality assurance. Local expert support and R&D assistance further simplify the certification process, providing manufacturers with a competitive edge in the global market. This strategic move underscores NSF's commitment to innovation, product safety, and the growth of the water industry in the EMEA region.
