Thermador Refrigerator Water Filters — BSH Built-In Family & Fit Pages

Thermador is the ultra-premium line of BSH (Bosch and Siemens Home Appliances), and its built-in refrigerators use the same proprietary BSH filter family as Bosch and Gaggenau — most built-in units resolve to the 11030857 / 00640565 cartridge line.

Thermador refrigerator filter questions, answered

Often — Thermador and Bosch are both BSH brands and the built-in lines share BSH cartridge families (11030857 / 00640565 line). The fit page confirms the exact part for your unit.

Typically inside the refrigerator compartment on the left wall, or behind the lower drawer. Use the full series number (KAD62…, T181D…) — the family suffix matters for the slot.

Yes — if the cartridge in your Thermador still has its part number printed on it (or the old one is in the cupboard), search that number directly. Fit pages list the OEM part number, its aliases, and the ClearFit cross-reference side by side.
