Here’s a straightforward guide on how to replace Sub-Zero refrigeration twist-in style water filters, commonly found in models like the Sub-Zero Classic Series and other dispenser and undercounter models.

First, ensure you refer to Sub-Zero’s specific guidelines, available in your model’s manual or on their website, under guides and quick answers.

This step is vital to confirm compatibility with factory certified parts, such as the 4204490 water filter, suitable for many models including the 648PRO.
