The right refrigerator water filter depends on your complete model and the cartridge or manufacturer part number. Use the old filter code as a second check; do not select a replacement from shape alone.

Open guide ↗What a filter code does not prove
Seeing a filter part number in an OEM catalog does not prove fit for every refrigerator from that brand. Likewise, NSF/ANSI certification applies to an identified product and specified contaminant claims, not to every cartridge that looks similar. Read the certification guide.
Check your exact model
For an old or damaged filter, consult the manufacturer parts finder and the appliance manual before ordering.
