Questions

Where is the model number on my Whirlpool 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 4396508 fits this model?: 2 independent filter suppliers (Discount Filter Store, ICEPURE) each publish a compatibility list naming ED25RFXFW01 for this filter, and they agree. How we build this.
