Replacement shower filter for the fixed models (1 pack for 12 months). These include the Sprite SLC models Original, Royale, and Prestige All-in-One Shower Filters. The Original All-In-One Filtered Shower head was the first to incorporate advanced filtration technology into a multi-function shower head.
Sprite products are NSF Certified to standard #177 for shower filtration. Don't be misled by companies who claim NSF Certified Filtration Media. It's not the same as being certified to Standard 177!
