WRX735SDHB00 specifics — where the filter actually lives
On the WRX735SDHB00, the cartridge top-left of the fresh-food compartment in most French-door layouts, away from the door bins — usually a kneeling-height or shoulder-height swap, not a teardown. Mechanically it is a quarter-turn twist-in seat: a quarter turn one way to release, the other to seat, and the only tool you need is a towel for the drip.
Field notes: the line is still live when you open the bay, so keep a towel in reach, and expect the filter-status light to need a reset before it believes the new cartridge. One prefix, one chassis family: WRX marks the French-door with exterior dispenser line in Whirlpool’s catalog, so cross-referencing cartridges by chassis rather than by door style keeps you out of the wrong-parts queue. Read the 00 ending as a revision marker — Whirlpool used it for running changes, none of which touched the EDR4RXD1 bay.
WRX vs WRT — what the prefix tells you
Prefix families here: WRX against WRT. Chassis first: French-door with exterior dispenser (WRX) versus top-freezer (WRT). The shared cartridge line covers both without adaptation. The WRX735SDHB00 was built across 2017 to 2021 on the official record, which brackets the cartridge generation you are shopping for.
Swap it in 5 minutes
- Twist the old cartridge a quarter turn counterclockwise and pull it straight down — keep a towel in reach for the dribble.
- Fill the new cartridge with cold tap water so the chamber is not fighting an air pocket.
- Offer the new cartridge to the bay, push up, and twist a quarter turn clockwise until the stop catches.
- Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.

WRX735SDHB00 filter questions
Clearing the filter status light on a Whirlpool WRX735SDHB00?
Press and hold the reset control until the light clears (a few seconds), with the new cartridge already seated — the WRX735SDHB00 owner’s manual lists the button location for your control panel.
WRX735SDHB00 with no water filter installed — safe, or does it need a bypass?
Nothing to buy — the EDR4RXD1 housing closes without a cartridge; water runs unfiltered until the next one goes in.
Are off-brand filters safe for a Whirlpool refrigerator?
Certified aftermarket cartridges are built to the same NSF test standards as the OEM part, and federal warranty law (Magnuson-Moss) protects your coverage when you use them.
Why is the OEM EDR4RXD1 cartridge so much more expensive?
Part of the OEM price is the badge and the distribution chain. Certified alternatives meet the same test standards at a lower unit price, especially in multi-packs.
How often should I replace the filter in my WRX735SDHB00?
Every six months or at the rated gallon capacity, whichever comes first — the EDR4RXD1 class cartridges all share that service interval.
Do I need to turn off the water supply to change it?
No — the bay is designed for a live swap. Expect a small dribble, keep a towel in reach, and flush a couple of gallons through the new cartridge before the first glass.
