The Bosch Evolution series of fridges introduced the CS-52 filter, a simply 'push up and twist' filter which has two distinctive 'wings' on the top of the long cylindrical body. The cartridges are manufactured for Bosch by 3M/Cuno group and whilst our cartridges are not supplied with 'Bosch' branding, the filters a produced in the same facility and to an identical specification (i..e they are branded as 3M filters).
These cartridges will replace part numbers 55866-05, 55866-06 , CS-51, 640565 and CS-52. It will also fit some Neff/Siemens fridges which are also produced by Bosch.
