Questions
- Where is the model number on my Bosch refrigerator?
- On a sticker inside the fridge compartment — usually on a side wall, on the ceiling, or on the frame behind the crisper drawers. It is not the number on the front of the door.
- How often should I replace it?
- Every six months, or sooner if the flow drops or the water starts tasting of chlorine again. Most fridges track this themselves and turn on a filter light.
- Do I have to buy the manufacturer's own filter?
- No. Aftermarket filters that carry NSF/ANSI 42 certification are tested to the same contaminant-reduction standard and typically cost half as much. Uncertified filters are not worth the saving.
- How do you know 644845 fits this model?
- Discount Filter Store publishes a compatibility list naming B20CS30SNS for this filter. Only one of the suppliers we track lists this model, so it is worth confirming against the filter currently in your fridge. How we build this.
