• NSF official public database (info.nsf.org, checked 2026-08-17) lists Kent RO Systems Ltd. (Noida, India) as holding active NSF/ANSI 58 certification for TDS Reduction across 24 named RO models. The exact product under review, Kent Supreme IoT RO Water Purifier, is NOT among those 24 listed names. The two closest matches are Kent Supreme+ Mineral RO and Kent Supreme Plus ZWW. Separately, Kent own official product page states that Supreme IoT and Supreme Plus share identical purification technology (RO+UV+UF+Alkaline+Copper+TDS Control), differing only in added IoT monitoring hardware - a manufacturer assertion, not independently corroborated. Whether NSF listed Supreme+ naming refers to the current Supreme Plus product is not confirmed; product naming may have changed since the NSF filing. Net finding: NSF/ANSI 58 certification is real and verifiable for Kent RO product line generally, and for specific named models, but cannot be honestly attributed to this exact product (Kent Supreme IoT) without a confirmed model-name match, which does not currently exist.
