Frizzlife M800: Frizzlife states the M800-new is independently tested/certified by SGS against NSF/ANSI 58 and 372 and displays NSF/ANSI 42, 53, 58 and 372 in product marketing. An exact-model NSF, WQA or IAPMO listing was not independently verified, so these standards are treated as third-party testing evidence rather than formal NSF/WQA/IAPMO certification. WINGSOL WS-QCJ-6RO: Amazon listing states NSF/ANSI 42, 53 and 58 certification. An exact-model certification record for WS-QCJ-6RO (F) was not independently located in the searched NSF, WQA or IAPMO listings. Treat these as unverified listing claims until WINGSOL supplies a certificate or certifier record.
