This is an original 3M twist-and-lock cartridge to fit the Bosch CS-52 Evolution series of refrigerators.
This filter is manufactured by 3M Purification to exactly the same specification as the original cartridge supplied by Bosch and is supplied with a 3M label as opposed to Bosch branding.
The filter contains activated carbon to improve the general taste of the water and remove impurities such as chlorine and dissolved organics, and also contains a poly-phosphate element, which acts as a scale inhibitor to give added protection to your appliance.
Performance and cartridge life is identical to that of the original Bosch cartridge and the filter should be changed at 6 month intervals in keeping with the manufacturer's specifications.
