Which EveryDrop Filter Fits My Whirlpool Refrigerator?

Do not choose by refrigerator brand or appearance alone

“Whirlpool refrigerator filter” is not a complete fitment description. Whirlpool has used several filter housings across French-door, side-by-side, bottom-freezer, and top-freezer designs. Two refrigerators that look nearly identical from the aisle can accept different cartridges. A seller’s broad statement that a filter “fits Whirlpool” means far less than a match to your complete model number.

EveryDrop’s official finder accepts model numbers for Whirlpool, Maytag, KitchenAid, JennAir, and Amana appliances. It then returns the approved filter for that particular model. That lookup should control the decision. Color, refrigerator age, door count, and cartridge location can help you understand what you see, but none should override the model result.

Step 1: find the refrigerator model number

Open the fresh-food and freezer doors and look for a rectangular model-and-serial tag. Whirlpool and EveryDrop identify several possible locations: the refrigerator ceiling, an interior wall, behind a crisper drawer, the cabinet frame exposed when a door opens, behind the lower kickplate, or on the rear cabinet. The model number is not the serial number.

Copy the complete model exactly, including letters before the digits and any suffix after them. A family name printed on a door or sales receipt is not enough. EveryDrop says its finder expects a six-to-twelve-character model number beginning with letters. If the label is difficult to read, take a well-lit photo and enlarge it rather than guessing whether a character is an O, 0, I, or 1.

The owner’s manual may also identify the water filter in its accessories or replacement-parts section. If you no longer have the paper manual, use Whirlpool’s official manuals lookup with the full model number.

Step 2: use the official Filter Finder

Enter the complete model into EveryDrop’s Filter Finder. Record both the friendly filter number and the exact cartridge code. For the four common cartridges covered here, those pairs are:

Treat those visual cues as a confirmation, not a fitment method. Packaging and label designs can change, aftermarket products imitate colors, and an old refrigerator can contain the wrong cartridge. The exact model lookup is stronger evidence.

If the finder returns Filter A, 5, 6, or another cartridge, do not substitute one of Filters 1–4. Go with the result for the model and verify it against the manual. If no match appears, recheck the model characters and contact EveryDrop or Whirlpool rather than buying the closest-looking option.

Step 3: compare the old filter without relying on it alone

Once the correct result is known, inspect the installed filter’s label. Removing it is unnecessary if its code is visible. If removal is required, first read the model’s replacement instructions so you know whether the housing uses a compartment door, push button, quarter-turn cap, or another release.

The old cartridge can provide useful supporting evidence:

• A current EveryDrop part code such as EDR1RXD1.
• A legacy Whirlpool number that the current cartridge replaces.
• The EveryDrop filter number printed prominently on the label.
• A distinctive connector and keying pattern that matches official product images.

It is not conclusive evidence if the refrigerator was purchased used, the cartridge was forced into place, the label is missing, or a third-party filter uses a confusing cross-reference list. Always reconcile the old label with the model lookup.

What the four filter numbers mean

EveryDrop’s numbers identify cartridge families, not filtration strength levels that you may freely choose. Filter 4 is not an “upgrade” for Filter 1, and Filter 1 is not a universal first choice. The housing’s physical interface and the refrigerator’s approved system determine the required number.

EveryDrop Filter 1: EDR1RXD1

Choose EDR1RXD1 only when the official model lookup or manual specifies Filter 1. Its replacement procedure depends on the refrigerator housing, so follow the appliance instructions and our EveryDrop Filter 1 EDR1RXD1 replacement guide. Owners may also see older part references; our planned EDR1RXD1 and W10295370A equivalence guide explains how to confirm a successor claim without dropping the model check.

EveryDrop Filter 2: EDR2RXD1

EDR2RXD1 is the current Filter 2 identifier. It belongs only in models assigned to Filter 2, and Whirlpool documents more than one possible housing location for some replacement procedures. See the EveryDrop Filter 2 EDR2RXD1 replacement guide before removing the old cartridge.

EveryDrop Filter 3: EDR3RXD1

EDR3RXD1 is EveryDrop Filter 3. The cartridge number must match the model; it should not be selected because an online listing includes a long list of brands. Installation guidance is in our EveryDrop Filter 3 EDR3RXD1 replacement guide.

EveryDrop Filter 4: EDR4RXD1

EDR4RXD1 is EveryDrop Filter 4. Owners replacing older UKF8001-family cartridges may encounter several suffixes and cross-references, making the full appliance model especially important. Use the EveryDrop Filter 4 EDR4RXD1 replacement guide for the physical change.

How to handle a legacy part number

An older filter may carry a Whirlpool engineering or service number instead of the current EveryDrop retail code. A documented successor can be valid, but a marketplace compatibility list is not enough by itself. Check the official finder and the current owner literature. Match the entire legacy number, including its final letter or revision suffix where present.

Do not assume that removing a suffix produces an equivalent part. Likewise, a replacement that physically enters the housing is not necessarily approved, sealed correctly, or certified for the same reduction claims. The refrigerator model remains the anchor for every cross-reference.

Before buying any replacement

Use this four-point check:

1. The complete refrigerator model in the official finder returns the same EveryDrop number.
2. The manual’s accessories section agrees, when available.
3. The old cartridge or housing label supports the match.
4. The package and listing show the exact current EDR code, not just “compatible with Whirlpool.”

If one point conflicts, pause. A wrong cartridge can fail to latch, leak at the filter head, restrict flow, or appear installed while not opening the internal water valves correctly. Never trim a key, transfer seals, lubricate the connector, or force a cartridge to overcome a mismatch.

What to do after the correct filter arrives

Read the installation sheet packaged with the filter and the refrigerator manual. Cartridge release methods differ. Protect the shelf or floor with a towel, remove the old filter using the intended button, door, tab, or turn, and install the replacement squarely without tools unless the manual specifically directs otherwise.

Flush the water system after installation. Whirlpool explains that flushing removes excess air, prepares the cartridge, and clears loose carbon. The required volume can vary—Whirlpool notes that some filters require one, two, or four gallons—so use the instructions supplied with the exact cartridge. Reset the filter status using the model’s control sequence only after the physical replacement and flush are complete. A reset changes a reminder; it does not confirm fit or restore a blocked water path.

If flow remains slow, the dispenser drips continuously, the filter will not lock, or water appears around the housing, shut off the refrigerator’s water supply as needed and revisit fit and seating. Do not keep forcing or overtightening the cartridge. Our Whirlpool refrigerator water filter leaking guide separates a seating problem from a damaged housing or service issue.

Final Verdict

Choose the cartridge from the refrigerator’s complete model number, not from brand, shape, color, or a seller’s generic fit list. Confirm the EveryDrop number against the manual and old label, then follow the procedure and flush volume for that exact filter. That extra two-minute fit check is the best protection against a cartridge that will not seat, leaks, or filters through the wrong system.
