Sub-Zero refrigerator filter references

The Sub-Zero model answer here establishes 4204490 only. The catalogue also contains 7045454 and 7042803, which need their own appliance confirmation.

Published model records

Choose the exact refrigerator model.

Each route keeps the documented device model, filter reference, region and manufacturer sources together. A source review records a documentary check against manufacturer materials; it does not mean the filter was physically fitted or tested.

Cartridge references and buying options

A listed cartridge family does not establish fit for an unlisted appliance. Amazon products and reference searches, manufacturer pages and retailer pages are labelled separately. Amazon links are paid links.
