Culligan certification listings
As of 2026-10-05, our certification index holds 542 active listings we can attribute to Culligan, from NSF International, IAPMO R&T and WQA Gold Seal: 113 of them under NSF/ANSI 44 (residential cation-exchange water softeners), all from WQA Gold Seal.
Listings by standard and certifier: NSF/ANSI 44 (WQA Gold Seal 113); NSF/ANSI 42 (IAPMO R&T 2 and WQA Gold Seal 117); NSF/ANSI 53 (IAPMO R&T 2 and WQA Gold Seal 17); NSF/ANSI 55 (NSF International 33); NSF/ANSI 58 (IAPMO R&T 2 and WQA Gold Seal 17); NSF/ANSI 177 (IAPMO R&T 2); NSF/ANSI 401 (IAPMO R&T 2 and WQA Gold Seal 8); NSF P231 (WQA Gold Seal 6).
Materials listings, which certify what a component is made of rather than anything it reduces: NSF/ANSI 61 (NSF International 4, IAPMO R&T 2 and WQA Gold Seal 192); NSF/ANSI 372 (IAPMO R&T 2 and WQA Gold Seal 483).
The NSF/ANSI 44 listings name these reductions: Hardness, Barium, Radium 226/228.
Our index reads only the IAPMO R&T, NSF International and WQA Gold Seal directories (read: NSF International on 2026-10-05, WQA Gold Seal on 2026-10-04, IAPMO R&T on 2026-08-23) and not CSA Group, ICC or UL Solutions, so a listing missing from it is not evidence that Culligan holds none.
