Safety boundary
- Use the exact model Owner’s Manual for the cartridge access and filter-indicator reset, and Bosch’s full E-Nr lookup if the appliance label includes a revision suffix.
- Bosch’s replacement guidance says to discard five minutes of dispenser water and one ice-bin worth of cubes after installation; verify any model-specific purge instructions.
- Check for leaks after installation; stop water dispensing if a leak appears.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.
Required identifiers
- Complete model from appliance label: B36CT81ENS

Compatibility rules
- Bosch’s model-specific sheet is the fit receipt; this internal-dispenser 800-Series model is not being matched from its resemblance to another Bosch cabinet.
- The cited manufacturer model/support/specification page is the fit receipt for B36CT81ENS; do not infer fit for another finish, suffix, revision, or nearby series.
Never assume
- BORPLFTR55 fits all Bosch refrigerators or another product merely because the name or filter appearance is similar.
- The refrigerator water cartridge is interchangeable with its air/odor filter, produce preserver, housing, or bypass plug.
- The manufacturer’s named contaminant/certification claims cover every contaminant or make microbiologically unsafe or unknown-quality water safe.
- Do not assume a filter fit after the refrigerator’s filter head has been replaced during repair; Bosch warns a different cartridge may be needed.
- Do not substitute a different Bosch filter family (for example BORPLFTR50) based on appearance or product series.
