Where Is the Water Filter in a Whirlpool Refrigerator? All 5 Slot Locations by Cabinet Type
A Whirlpool refrigerator’s water filter lives in one of five possible positions, decided by cabinet style and filter generation — and the fastest way to find yours is the machine’s model number, not a physical hunt. In quick-answer form: French-door and side-by-side machines with interior slots carry the filter in the upper-right or upper-left fresh-food corner (Filter 1/2/4); machines with base-grille slots carry it behind the kickplate at the bottom front (Filter 3/5); and a minority of installations put a cartridge in-line on the supply line at the back. Find the slot, read the filter number printed on the cartridge, and the replacement decision is made.
The reason this question generates so much searching: none of the five positions is labeled from the outside, Whirlpool has used all of them across two decades, and the official help pages cover one filter at a time. A repair-forum regular summarized the genre: people open the fridge, see no obvious cartridge, conclude their fridge “has no filter,” and buy the wrong thing — usually a universal inline kit they did not need. The 30-second model-number method below prevents all of it.
Quick Answer: The 5 Positions
| # | Position | Typical cabinet styles | Typical cartridge |
|---|---|---|---|
| 1 | Upper-right interior, fresh-food compartment | French door, some side-by-side | Filter 1 / Filter 2 / Filter 4 |
| 2 | Upper-left interior | Some French-door and bottom-freezer | Filter 1 / 2 variants |
| 3 | Base grille, behind the kickplate (left or right) | Older side-by-side, some bottom-freeze | Filter 3 (push-button) / Filter 5 (quarter-turn) |
| 4 | Lower interior / drawer-adjacent slot | Some bottom-freezer generations | Filter family by model |
| 5 | In-line on the supply line, behind the fridge | Aftermarket or select models | Inline 1/4-inch cartridge |
Positions 1–4 are the factory slots; position 5 is either a factory design on a few models or — far more often — a previous owner’s addition. Each position’s telltale signs are below, but the definitive identification is the model-number lookup, covered after the table.
By Cabinet Style: What You’re Looking For
French-door (two doors up, freezer drawer below). Run your hand along the top interior walls of the fresh-food compartment. The filter sits behind a small hinged or snap-off plastic cover — usually upper-right, sometimes upper-left. On some Filter 4 machines the cartridge lies in a flip-down tray. If the top walls are bare, check behind the lowest drawers (position 4) before assuming no filter exists.
Side-by-side. Two candidates: the interior top wall (same cover as above) or — on the classic layout — the base grille. Kneel down: the kickplate below the doors has a rectangular cutout or button on one side; the cartridge cap faces forward behind it. This is the push-in family (Filter 3) or quarter-turn (Filter 5) territory.
Bottom-freezer (single door up). Same interior-wall positions as French-door; base-grille variants exist on older units. Cover styles vary by year — hinged flap, snap-out panel, or a visible cartridge cap needing no cover removal.
Top-freezer (freezer above). The least common water-filter cabinet. When present: interior top wall or base grille. A significant share of top-freezer machines have no water filter at all — no dispenser, no ice maker water line, nothing to find. Confirming “no filter exists” is a legitimate outcome of the model-number check below, and it beats an hour of panel-hunting.
The Definitive Method: Model Number → Slot → Filter
- Find the model sticker. Inside the fresh-food compartment: side wall, ceiling near the controls, or behind a crisper drawer. The number starts with letters (e.g., WRF…) followed by digits.
- Search the model number plus “water filter” — the parts listings and compatibility pages that return state the exact cartridge (Filter 1–6 family) and usually show the slot in the diagram.
- Read the cartridge itself once found: the filter number is printed large on the cap or body. That printed number is the single source of truth — stronger than any guide including this one.
One caveat that trips even careful owners: water filter vs. air filter. Whirlpool machines also carry an air-purification cartridge (EveryDrop AIR1-family), usually in the same compartments and behind similar covers. The air filter is flat and wide; the water filter is a cylinder. Pulling the air filter and ordering “the filter for a WRS…” is a real ordering error with a real return-shipping cost. The cylinder is water; the flat puck is air.
If the model lookup says your machine has a water filter but the slot is bare: someone removed the cartridge (or a bypass plug — see bypass plugs explained) and never replaced it. An empty water slot usually means no dispenser flow, which is the tell owners noticed in the first place.
“I Found a Filter at the Back of the Fridge”
Cartridges on the supply line behind the machine (position 5) are inline filters: cylindrical, with 1/4-inch compression fittings at both ends, strapped to the line. Two origins. A few models shipped that way from the factory. Most were added by an owner or installer — commonly on machines whose internal slot failed, or on well-water setups wanting sediment pre-treatment. Inline cartridges are replaced by unscrewing the fittings (water off first — there is no auto-shutoff on an inline), and any compatible 1/4-inch carbon cartridge works; the inline installation guide covers the full procedure.
Inline-plus-empty-internal-slot is a legitimate configuration: upstream inline filtration with the internal slot bypassed. If you inherit such a machine, decide which stage you want to maintain — running both is redundant, running neither means the dispenser line is raw tap.
Found It: Next Steps
Once the cartridge is in hand, the printed number does the shopping: Filter 1 (EDR1RXD1), Filter 2 (EDR2RXD1), Filter 3 (EDR3RXD1), Filter 4 (EDR4RXD1), Filter 5 (EDR5RXD1), plus Filter 6/A/Ice siblings on machines with a second, dedicated ice-maker cartridge. The full replacement procedure — mechanism-specific removal steps, flushing, resetting — is the Whirlpool change guide. If the old cartridge will not come out, that is its own genre of problem: Whirlpool filter stuck — five fixes. And the sister brands (KitchenAid, Maytag, Amana, Kenmore 106) use the same slots and cartridges — the model number, not the door badge, decides.
FAQ
Does every Whirlpool refrigerator have a water filter?
No. Machines without a water dispenser or ice maker have no water line and no filter — common in top-freezer configurations. The model-number lookup answers this definitively; “no filter exists” is a normal result, not a failure of the search.
Can a Whirlpool fridge have two water filters?
Yes, on some French-door machines: a primary cartridge plus a dedicated ice-maker cartridge (the Filter 6/A/Ice family slots). They are different parts with different capacities — read the number on each. Two identical primary slots on one machine is rarer and model-specific; the parts diagram shows it when true.
My filter cover is behind the drawers and I can’t reach it. Now what?
Some lower-interior slots need the drawer pulled fully out (lift-and-pull past the stops — no tools on most models) for access. If the cartridge still cannot be reached cleanly, the slot may be an ice-maker cartridge; check the model diagram before forcing access.
How do I know if the slot I found is for water or air?
Shape and plumbing: the water cartridge is a cylinder with a bayonet or push-in base and sits in a bored housing; the air cartridge is a flat round or rectangular puck in an open clip, nowhere near a water line. The air-vs-water confusion is the top ordering error this page exists to prevent — when in doubt, pull it: a water cartridge’s base has water-path openings; an air puck is solid.
