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. Waterdrop G2P600: Exact-model G2P600 is listed to NSF/ANSI/CAN 372 through IAPMO R&T. Separate exact-model materials document SGS and CSA third-party testing according to NSF/ANSI 42, 53, 58 and 401. Testing to these standards should not be represented as certification/listing to those standards.
