Whirlpool WRB322DMBB Water Filter Replacement
Why The Whirlpool WRB322DMBB refrigerator…
The Whirlpool WRB322DMBB refrigerator requires the GXRTDR water filter. This model is a 33" bottom-freezer unit without a built-in water dispenser, meaning the filter is an inline type, not a cartridge located inside the refrigerator compartment. The GXRTDR is specifically designed for external inline installation with the 1/4-inch compression fittings common to this refrigerator's water supply line.
Common Mistakes When Ordering
- Ordering an internal cartridge filter designed for models with an in-door dispenser.
- Confusing the WRB322DMBB with similar Whirlpool models that use a different inline filter SKU.
- Attempting to install the filter without first shutting off the water supply.

Location & Installation: The GXRTDR water filter for the Whirlpool WRB322DMBB is installed externally in the 1/4-inch water supply line behind the refrigerator.
