KitchenAid Refrigerator Water Filters: Which EveryDrop Filter Fits Yours?

KitchenAid does not run a separate filter programme hiding somewhere — KitchenAid is part of the Whirlpool family, and its refrigerators drink through EveryDrop cartridges, Whirlpool’s own filter brand. That single fact resolves most KitchenAid filter confusion: the question is never which brand of filter a KitchenAid takes, only which number. For most KitchenAid French door owners the answer is Filter 2. This guide maps the model families to their filters, shows the ten-second check that settles it, and walks through the change.

Start With the Label — It Outranks Every Table

Pull your current cartridge and read it. If it says Filter 2 or EDR2RXD1 (or the older Whirlpool number W10413645A, or KitchenAid’s own P9WB2L), your replacement is the EDR2RXD1 — full stop. Any other EveryDrop number on the label points to that number’s cartridge instead. Model tables, this one included, are shortcuts; the label on the filter that just came out of your fridge is the verdict.

KitchenAid Model Families and Their Filters

The store’s EDR2RXD1 product page carries the long compatible-model list, and it is thick with KitchenAid: KRMF and KRFC French door models run through it, and the page also lists the cartridge under the KitchenAid name KAD2RXD1. If your model starts KRM, KRF or KRB, Filter 2 is the strong favourite — then the label confirms it.

Filter 2 in Detail: The KitchenAid Workhorse

The EDR2RXD1 is a push-button cartridge that lives in the upper-right interior compartment of the fridge — the EDR2RXD1 page describes it exactly that way: if your refrigerator uses a push-button filter in the upper-right interior, this is likely your fit. Facts from that page:

• Also called Filter 2, 9082, W10413645 and W10413645A; KitchenAid-branded as P9WB2L and KAD2RXD1
• Made for Whirlpool, Maytag, Amana, KitchenAid, JennAir and Kenmore refrigerators
• NSF certified, with the page listing certified reduction of 99% of microplastics among its contaminant reductions
• Triple Filtration Technology, flow rate around 0.6 GPM
• Lasts about 6 months or 200 gallons, depending on water use and quality
• Install type: push-button / twist-in, tool-free

The Other Filters a KitchenAid Can Take

KitchenAid’s range is wide enough that some models use the rest of the EveryDrop family. Each is a different shape for a different housing, and none of them interchange:

• Filter 1 (EDR1RXD1) — interior twist-in cartridge, on a range of side-by-side and French door models.
• Filter 3 (EDR3RXD1) — base-grille cartridge with a quarter-turn cap, common on side-by-side models.
• Filter 4 (EDR4RXD1) — the cartridge also known by its older number UKF8001.
• Filter 5 (EDR5RXD1) — interior twist-in for select models.
• Filter A (EDRARXD1) — the lettered cartridge, on the models whose manuals specify Filter A.

Our guide to the complete EveryDrop range explains the whole numbering system, and our dedicated Filter 2 guide goes deep on compatibility and part numbers for the cartridge most KitchenAid owners need.

How to Change a KitchenAid Filter, by Housing

Filter 2 (push-button, upper-right interior):

1. Press the eject button or lift the cover in the upper-right compartment; the old cartridge pops partway out.
2. Pull it straight out; a few drops of water are normal.
3. Remove the new cartridge’s protective cap, align it, push firmly and turn clockwise until it clicks.
4. Flush 2–3 gallons through the dispenser and discard them, plus the first batch of ice.
5. Hold the filter reset button for about 3 seconds until the indicator returns to green or blue.

Filter 3 (base grille): twist the cap a quarter turn counterclockwise, pull the cartridge out, seat the new one and turn the cap back until it locks — then flush and reset as above.

Filters 1 and 5 (interior twist-in): open the housing cover, twist the old cartridge counterclockwise and pull, seat the new one with a clockwise twist until it clicks — then flush and reset.

Filter 4 and Filter A: follow the same pattern for their housings (grille or interior twist-and-lock respectively); the universal rules never change — seat it fully, flush properly, reset the light manually.

Signs Your KitchenAid Filter Is Done

The calendar says six months, but the water usually speaks first: the dispenser stream thins, ice cubes shrink or turn hollow, and a chlorine taste or smell creeps back into water and ice. The indicator light is the last warning, not the first. A saturated carbon block stops capturing contaminants while still passing water, so stretching a finished cartridge to save a few dollars protects nothing — change on the signs, or on the six-month mark, whichever arrives first.

What a Genuine KitchenAid Filter Should Cost

The genuine EDR2RXD1 — like every genuine EveryDrop cartridge in the range — is $39.99 one-time at Discounted Filter Store, with free US shipping on any order size. Multi-packs (up to $147.99 for Filter 2) lower the per-filter price. The comparison that matters: the official EveryDrop store charges $59.99 for the same cartridge bought one-time, or $48 only with a subscription commitment; Filters Fast ships free only at $99+ and Discount Filter at $70+. Genuine OEM, Whirlpool-specified for your KitchenAid, with no subscription and no minimum basket.

Orders are processed within 1–2 business days and delivered in 3–5 business days via USPS, and unopened filters return within 30 days, free, on a prepaid label.

Frequently Asked Questions

Which water filter does my KitchenAid refrigerator take? Most KitchenAid French door models (KRMF, KRFC, KBFN families) take EveryDrop Filter 2, part EDR2RXD1. Other models take Filters 1, 3, 4, 5 or A depending on the housing. The label on your current cartridge is the final authority.

Are EDR2RXD1, P9WB2L and KAD2RXD1 the same filter? Yes — they are names for the same Filter 2 cartridge: EDR2RXD1 is the current EveryDrop part number, P9WB2L is the KitchenAid-branded version, KAD2RXD1 is another KitchenAid name the store’s product page lists, and W10413645A is the older Whirlpool number it replaces.

Is EveryDrop really the right brand for a KitchenAid? Yes. KitchenAid is a Whirlpool brand, and EveryDrop is Whirlpool’s filter line — the cartridges are made for Whirlpool, Maytag, Amana, KitchenAid, JennAir and Kenmore refrigerators, as the product page states.

How often does a KitchenAid filter need changing? About every 6 months or 200 gallons for Filter 2, per its product page — sooner if flow slows or taste and odour return.

Why is the genuine filter $39.99 here but $59.99 at the official store? Same genuine Whirlpool-made cartridge, different markup and shipping policy: $39.99 one-time with free shipping on any amount here, versus $59.99 one-time (or $48 by subscription) at the official store.

What if I order the wrong EveryDrop number? Do not force it into the housing — the numbers are different shapes and are not interchangeable. Unopened filters can be returned within 30 days, free, with a prepaid label, and sending us your model number first lets us confirm the right one before you order.
