Whirlpool refrigerator water filters

everydrop Filter 1–4 cartridges, including UKF8001.

A whirlpool fridge water filter replacement is decided by the housing, not the model year: every refrigerator built on the same housing takes the same cartridge, which is why a single part number such as EDR1RXD1 can cover many models. The list below pairs all 3 Whirlpool models in this reference set with the cartridge each one takes.

Which Whirlpool fridge water filter do I need?

Pull the cartridge currently in the housing and read the number on its face — that is the part you need. If the housing is empty, find the model sticker inside the fresh-food compartment and look the model up; the most common cartridge in this set is Whirlpool EDR4RXD1, which fits 10 models. Part numbers are cross-referenced above, so an old box marked with a different code can still be the same cartridge.

Common questions

What water filter does my Whirlpool refrigerator take?
Whirlpool uses several filter housings, so the cartridge is set by the model number rather than the brand alone. In this reference set the most widely used is EDR4RXD1 (10 models). Look your model up under Refrigerators above, or read the number printed on the cartridge you are removing.
Are Whirlpool refrigerator water filters interchangeable?
Only within the same housing. Two cartridges with different part numbers can be the same physical part when they share a housing family — those cross-references are listed on each cartridge page. A cartridge from a different housing will not seal, even if it looks similar.
How do I find my Whirlpool filter part number?
Two places: the model sticker inside the fresh-food compartment, or the face of the cartridge currently installed. The cartridge number is the definitive one, because manufacturers change suppliers mid-model-year without changing the refrigerator model code.
