Whirlpool EDR3RXD1

everydrop Filter 3, the long push-in cartridge that lives in the base grille of Whirlpool side-by-side refrigerators. Older part numbers 4396710 and 4396841.

About this cartridge

EDR3RXD1 is the retail name; everydrop lists P1WB2 and P1WB2L as the numbers it supersedes, and the pre-everydrop codes 4396710 and 4396841 still appear on older fridge documentation. Kenmore packs the same cartridge as 46-9083 and 46-9030.

This cartridge sits in the left side of the base grille at floor level — you eject it with a button rather than twisting it, which makes it physically impossible to confuse with the twist-lock Filters 1, 2 and 4 that sit inside the compartment.

everydrop certifies Filter 3 to NSF/ANSI 42 and 53 at 200 gallons or six months, with a stated 0.5–<1.0 µm rating, and claims reduction of 73 contaminants including lead, mercury, asbestos and pharmaceuticals (per the official everydrop Filter 3 product page).

These part numbers refer to the same physical cartridge. If the number on your old filter is in this list, this is the right replacement.

Which refrigerators it fits

Whirlpool has not published a model-level list for this cartridge that we can verify, so we do not publish one either. The number on the cartridge you are removing is the reliable check.

Replacing it

1. Turn the old cartridge a quarter turn counter-clockwise and pull it straight out. Keep a towel under it — a few ounces of water will come out.
2. Remove the protective cap from the new cartridge and check that the O-rings are seated flat in their grooves.
3. Push it in and turn clockwise until it stops. Run two to three gallons through the dispenser to flush carbon fines, then reset the indicator.
