Swimming Pool, Spa and Hot Tub Products Certification Process

NSF certification of pool, spa and hot tub equipment covers many products used in public and private pools, including filters, drain covers, pumps and disinfection equipment. Our certification program includes laboratory testing along with audits of production facilities to verify ongoing compliance with the design and performance standards of applicable American or international standards.

The NSF certification mark on a pool, spa or hot tub component means that the product was reviewed and certified by NSF International to meet applicable American National Standards for design, construction and/or performance.

As further protection for consumers, NSF also conducts annual audits at each authorized production facility and regular re-testing of certified products to confirm that they continue to comply with all requirements for certification. We also verify that labeling and product literature are true and accurate with respect to NSF certification claims.
