Fitment notes

Everydrop Filter 4 is the green twist-in EDR4RXD1 used by the five Whirlpool and Maytag French door refrigerator families below. Everydrop rates it at six months or 200 gallons and claims NSF/ANSI 42, 53 and 401. Manufacturer performance sheets and manuals also name EDR4RXD1B, the older UKF8001 family, Whirlpool WHR4RXD1 and KitchenAid KAD4RXD1 for this fit. Match the complete refrigerator model number before ordering because the same appliance brands use several filter shapes.
