Open the refrigerator and locate the permanent model-and-serial label, commonly found on a side wall, ceiling, door frame, or behind a crisper drawer. Confirm that it reads B36CT80SNB, including the final letters and numbers.

- Compare 11032531 with the number on the installed cartridge.
- Open the official Bosch confirmation link before ordering.
- Stop if the old and new filter connections do not match.
How often should it be replaced?
The listed replacement interval for Bosch UltraClarity® Pro is every 6 months or 250 gallons. Replace sooner if the refrigerator manual directs you to, the rated capacity is reached, dispenser flow drops noticeably, taste changes, or the filter indicator requests replacement.
A reset light does not renew the cartridge. Reset the indicator only after installing and flushing the correct new filter.
Installation and flushing
Follow the Bosch manual for the filter compartment, cartridge orientation, flushing volume, and filter-status reset. Follow the B36CT80SNB owner’s manual for the exact compartment location, release method, flushing volume, and reset sequence.
Air may cause temporary sputtering during the first dispensing cycles. Continue only as directed by the manual and inspect the housing for leaks. If water continues to escape, shut off the supply and recheck the cartridge, seals, and housing.
OEM versus compatible filters
Use 11032531 as the reference part when comparing alternatives. A compatible cartridge should explicitly identify that OEM number and provide independent evidence for its certification claims. A similar-looking connector or a broad statement that it “fits Bosch” is not sufficient.
For the lowest-friction choice, use the manufacturer-approved filter. If considering a third-party option, confirm the exact fit, certifier listing, seller, and return policy before opening the package.
