What to confirm before buying

Designed for select Bosch French-door refrigerators; verify the complete model in Bosch's parts lookup. The model label is usually inside the fresh-food compartment or on the door frame. Copy every letter and number, because a suffix can identify a different production revision.

  • Match the complete refrigerator model.
  • Compare the old cartridge part number as a second check.
  • Confirm the result through the manufacturer link on this page.
  • Keep the packaging closed until the connection and locking tabs match.

Alternate and replacement part numbers

People may search for this fridge filter using its family name, current OEM number, an older number, or a related manufacturer label. For Bosch UltraClarity® Pro, common reference terms include:

  • BORPLFTR55
  • REPLFLTR55
  • RA450022

Use these numbers only as cross-references. The complete refrigerator model and the manufacturer’s current recommendation should decide the final replacement.

Replacement timing

The listed interval is every 6 months or 250 gallons. Treat that as a manufacturer-style baseline rather than a guarantee. Heavy use, high sediment, reduced dispenser flow, unfamiliar taste, or a filter alert may justify earlier replacement.

After installation, flush the cartridge according to the refrigerator manual, inspect the housing for leaks, and reset the filter indicator only after the new filter is seated correctly.

OEM and compatible alternatives

Begin with 11032531 as the reference OEM part. A third-party filter should explicitly name that part, fit the same housing, and provide independently verifiable certification for any contaminant-reduction claims. Similar shape or a general claim of brand compatibility is not enough.

We do not assign performance ratings based on retailer descriptions. Compare the exact cartridge listing, certifier database, seller identity, and return policy before choosing an alternative.
