Full list must be harvested from the FiltersFast URL in sources before publishing as complete. NOT interchangeable with standard UltraClarity (BORPLFTR10) - different physical cartridge.
Certification
Maker claims NSF/ANSI 42, NSF/ANSI 53, NSF/ANSI 401 — no independent certifier listing was found when checked on 2026-11-11. Treat the claim as unverified.
Bosch/FiltersFast/DiscountFilters copy states system tested and certified by NSF International against NSF/ANSI 42, 53 and 401 for chlorine, chloramines, lead, cysts, pharmaceuticals etc. However fridge.com's check of the BSH info sheet (doc 21-BSH-0989) notes the sheet itself states no certifier, standard, capacity or flow. No NSF directory listing was opened in this pass, so status is manufacturer_claimed, not certified.
