Frequently asked
What water filter does a FRS3R4EB2 refrigerator use?
The FRS3R4EB2 uses the WF1CB water filter.
Does the WF1CB remove lead?
Our data doesn't show an NSF/ANSI 53 lead-reduction claim for the WF1CB. Check the filter's own NSF certification sheet before assuming it reduces lead.
Should I buy the OEM filter or an aftermarket one?
The OEM WF1CB is the safe, exact-fit choice. A cheaper aftermarket filter can fit the same slot too - just confirm it carries its own independent NSF certification for the contaminants you care about, since a generic aftermarket filter without certification isn't proven to remove anything.
How often should I replace the WF1CB?
Most refrigerator filters are replaced every 6 months regardless of the exact model - use your fridge's filter-change indicator as the trigger if it has one.
Where is the water filter on a FRS3R4EB2?
Location varies by fridge design - commonly inside the fridge compartment (upper right or lower kickplate/grille) or in the water line behind the unit. Check your owner's manual for the exact spot on this model.
