Thermador Refrigerator Water Filters

Thermador refrigeration is built by the BSH group, and the filtration follows the group parts pool: the 9000 194412 cartridge line dominates — 20 of the 36 Thermador-directory models in our fit library run it. Columns and built-in bottom-mounts are the heartland.

What Thermador ownership changes is the service expectation, not the cartridge: parts listings under the Bosch badge for the same 194412 part are identical, which quietly widens your sourcing options beyond the luxury-parts channel. The smaller dedicated lines (00750673 and the BORPLFTR55 shared with Bosch built-ins) cover the rest of the fleet. Model number in, correct line out — the luxury badge doesn’t get a pass on the check.

Thermador filter FAQ

Which water filter does my Thermador refrigerator use?

Most Thermador refrigeration runs the BSH-group 9000 194412 cartridge — 20 of the 36 models in our fit library. The remainder split between the 00750673 dedicated line and the BORPLFTR55 shared with Bosch built-ins. Columns and integrated units vary by generation, so the model plate check (inside the unit, usually on the left wall or frame) plus the finder is the reliable path. Our library covers the full Thermador directory.

Are Thermador and Bosch filters interchangeable?

When the part number matches, the parts are identical — Thermador and Bosch are both BSH-group brands sharing one engineering pool, and the 9000 194412 cartridge is the same physical part sold under either badge. That makes cross-badge sourcing legitimate and often cheaper. What is not safe is assuming interchange: Thermador’s dedicated lines (00750673) and some built-in platforms use parts that a Bosch freestanding machine would never see. Match the part number, not the brand badge.

How often should a Thermador filter be changed?

Follow the BSH-group cycle: 6 months is the standard specification for the 194412 line, and the panel indicator counts time rather than volume. Luxury-built dispensing systems are flow-sensitive like their Bosch siblings — slowing dispenser flow is usually the first sign of a loaded cartridge, arriving before any taste change. Pair the swap with the 12-month air-cartridge check if your unit carries one, and the maintenance calendar stays simple.

Where do I buy Thermador water filters?

Through Thermador’s parts network, BSH-group dealers, and — for the shared cartridges like the 194412 — the same listings that serve Bosch owners, often at meaningfully better prices. The compatible-cartridge market also covers the 194412 line, with verified options listed on each model page in our library. The discipline is the part number: Thermador’s dedicated lines (00750673) don’t have Bosch-twin listings, so verify before ordering from a cross-badge source.

My Thermador column doesn't dispense water — does it even have a filter?

Check the spec rather than assuming. Not every Thermador column carries a dispenser or internal filtration — the pure refrigerator and freezer columns often have neither, with water and ice handled by a companion unit or the home’s supply filtration. Where a unit does dispense, the cartridge follows the parts pool above. The model + serial plate settles it in one look; if the unit is a non-dispenser column, the “filter” in your kitchen is upstream, not inside the machine.
