Counterfeit warning signs for EDR3RXD1
Check seller, packaging, markings and certification references. The published Everydrop record identifies this cartridge as Refrigerator Water Filter 3.
Start with fit verification
Match the complete refrigerator model and the code printed on the existing cartridge. Official filter for select Whirlpool Corporation refrigerators. Confirm with Everydrop's Filter Finder. Do not infer compatibility from color, overall shape or brand alone.
Service baseline
The available record uses 6 months or 200 gallons, subject to the manufacturer’s whichever-comes-first instructions. Water quality, usage and long periods of inactivity may justify earlier service.
Safe action
Filter 3 is typically located in the base grille; follow the model manual and official installation instructions. If the cartridge does not seat normally, water does not return after flushing, or the housing leaks, stop and use the refrigerator’s model-specific manual.
Evidence
Open the linked source before purchase. FilterRef separates published compatibility from general troubleshooting guidance and does not treat an aftermarket cross-reference as automatically equivalent.
