What to match before buying
- Whirlpool’s model-revision table identifies EDRARXD1 for WRF535SWHZ11.
- WRF535SWHZ10 uses Filter 4 (EDR4RXD1); WRF535SWHZ11 uses Filter A (EDRARXD1). The base name WRF535SWHZ alone does not choose a filter.
- The documented revision must match your label. Other revision codes need their own manufacturer check.
Find the model and filter codes
- Photograph the rating label inside the refrigerator.
- Confirm the full model reads WRF535SWHZ11, including the final 11.
- Compare EDRARXD1 with the cartridge reference in the refrigerator documentation.
- Match the final Amazon reference, seller and pack before ordering.
Other models and cartridge variants
- Do not remove the final revision digits or substitute a related model code.
- This record covers US specifications. A local Amazon item does not approve another regional refrigerator model.
