Whirlpool 4396508 Refrigerator Water Filter
The short answer on the 4396508
Whirlpool 4396508 is the factory number the Filter 5 slot carried through the 2000s — commonly paired with the 4396547 code on KitchenAid and Whirlpool side-by-side plates. When the EveryDrop program took over, the cartridge kept its 240-gallon media and took the number EDR5RXD1. It carries 42+53+401 (dual-source verified). Path: 4396508 superseded by EDR5RXD1 (EveryDrop Filter 5).
Cross-checked fit coverage: 1690 refrigerator models in the library behind this site. Install time: 5 minutes, no tools. Plates often list 4396508 and 4396547 together; they are twin codes for one cartridge, not two slots. Only one is fitted at a time in a single-filter fridge.

Swap it in 5 minutes
- Pull the old cartridge straight out of the header — expect a small spill, not a flood.
- Align the new cartridge with the keyed slot; it only goes in one orientation.
- Push the cartridge home until the retention latch clicks.
- Run 1–2 gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.
What the 4396508 is actually certified to remove
The OEM carries 42 + 53 + 401 — this one is dual-source verified The honest framing: the two tiers that matter in compatibles are 42-only (taste, chlorine, sediment) and 42+53 (adds tested lead and cyst reduction). A claim is a part-number × version fact, and NSF listings move with annual re-tests — verify in the certified-product database before you rely on one. And note the PFOA/PFOS reduction claim sits under NSF/ANSI 53 (P473 protocol), never under 401, whatever a listing says.
Is the 4396508 the same as the 4396547?
Yes — twin factory codes for one cartridge. Whirlpool listed them together on plates and parts sheets; a listing for either number fits the same push-in Filter 5 bay.
What replaced the Whirlpool 4396508?
EveryDrop Filter 5, retail number EDR5RXD1. The media line is continuous — same capacity, same bay — so the replacement path is a straight number swap with no adapter.
Does the 4396508 have a chip inside?
No. This number predates chip-locked cartridges by a decade; nothing in the Whirlpool 4396-series ever carried electronics.
How long does a 4396508-slot cartridge last?
Around 240 gallons or six months — the Filter 5 slot is the high-capacity position. Compatibles that quote a shorter life are usually re-rated 200-gallon media in the same housing.
