Which water filter fits Whirlpool WRF535SWHW?
Our compatibility guide associates Whirlpool refrigerator model WRF535SWHW with everydrop® Filter 4, part EDR4RXD1. This is the identifying number to compare when searching for a replacement refrigerator filter, fridge filter, or compatible cartridge.
Whirlpool refrigerators can use several physically different everydrop cartridges. Similar refrigerator styling does not identify the filter, so the complete model number is the safest starting point. Do not choose a cartridge based only on refrigerator color, door arrangement, or product photography.

Open the refrigerator and locate the permanent model-and-serial label, commonly found on a side wall, ceiling, door frame, or behind a crisper drawer. Confirm that it reads WRF535SWHW, including the final letters and numbers.
- Use the appliance model—not the serial number.
- Compare EDR4RXD1 with the number on the installed cartridge.
- Open the official Whirlpool confirmation link before ordering.
- Stop if the old and new filter connections do not match.
How often should it be replaced?
The listed replacement interval for everydrop® Filter 4 is every 6 months or 200 gallons. Replace sooner if the refrigerator manual directs you to, the rated capacity is reached, dispenser flow drops noticeably, taste changes, or the filter indicator requests replacement.
A reset light does not renew the cartridge. Reset the indicator only after installing and flushing the correct new filter.
Installation and flushing
Follow the model manual to release the old cartridge, align the new filter with the housing, and lock it using light hand pressure. Follow the WRF535SWHW owner’s manual for the exact compartment location, release method, flushing volume, and reset sequence.
Air may cause temporary sputtering during the first dispensing cycles. Continue only as directed by the manual and inspect the housing for leaks. If water continues to escape, shut off the supply and recheck the cartridge, seals, and housing.
OEM versus compatible filters
Use EDR4RXD1 as the reference part when comparing alternatives. A compatible cartridge should explicitly identify that OEM number and provide independent evidence for its certification claims. A similar-looking connector or a broad statement that it “fits Whirlpool” is not sufficient.
For the lowest-friction choice, use the manufacturer-approved filter. If considering a third-party option, confirm the exact fit, certifier listing, seller, and return policy before opening the package.
