If your KitchenAid’s manual, the sticker inside the door, or the cartridge you just pulled out says KAD2RXD1, here is the whole story in one sentence: KAD2RXD1 is KitchenAid’s own name for EveryDrop Filter 2, part EDR2RXD1 — the same genuine Whirlpool-made cartridge, also sold under the KitchenAid number P9WB2L. KitchenAid is a Whirlpool brand and EveryDrop is Whirlpool’s filter line, so the “KitchenAid filter” and the “EveryDrop filter” were never two different parts. This guide covers the three-names puzzle, which KitchenAid models use the Filter 2 housing, how the change works, and what the genuine cartridge should cost.
Three Names, One Filter
Filter 2 has collected more aliases than any other cartridge in the range. The EDR2RXD1 product page lists its names and cross-references directly:
| Name on your old filter or manual | What it is |
|---|---|
| KAD2RXD1 | KitchenAid’s branded name for Filter 2 — listed on the product page |
| P9WB2L | The other KitchenAid number for the same cartridge — also listed on the page |
| EDR2RXD1 | The current EveryDrop part number to order by |
| Filter 2 / 9082 | The range name and the short cross-reference number |
| W10413645 / W10413645A | Older Whirlpool part numbers for the same cartridge |
| Kenmore 46-9082 | The Kenmore-badged version, for Whirlpool-built Kenmore fridges |
As always, one rule outranks every chart: the label on the cartridge you removed is the final authority. If it carries any name in the left-hand column, the EDR2RXD1 is your replacement. If it carries a different EveryDrop number, that number’s cartridge is the one to order — the housings differ and the filters do not interchange. Our Kenmore refrigerator water filter guide shows the same translation from the Kenmore side, 46-9082 row included.
Which KitchenAid Models Use Filter 2?
The product page describes the housing plainly: if your refrigerator uses a push-button filter in the upper-right interior compartment, this replacement may be the right fit. On KitchenAid, that housing belongs mainly to the French door families — the store’s compatible-model data for this cartridge runs thick with KRMF and KRFC French door models (the KRMF706 and KRFC300/KRFC604 style families), which is why Filter 2 is the cartridge most KitchenAid owners end up ordering. The page lists the cartridge as working with selected models from Whirlpool, Maytag, Amana, KitchenAid, JennAir and Kenmore.
Two checks take ten seconds. First, the housing: open the fresh food compartment and look at the upper-right corner — a push-button housing with a cover or eject button is Filter 2’s home. Second, the label: pull the old cartridge and read it. French door KitchenAids from other generations can take Filters 1, 3, 4, 5 or A instead, and our KitchenAid refrigerator water filter guide maps each family to its filter so you can see where yours falls.
What the Genuine Filter 2 Is Certified to Do
The EDR2RXD1 page’s specification table is specific, and it is the reason the genuine cartridge is worth distinguishing from a copy:
- NSF/ANSI Standards 42, 53 and 401, plus CSA B483.1 certification
- Certified to reduce 99% of microplastics, per the page’s contaminants field
- Triple Filtration Technology with an activated carbon block
- Flow rate of about 0.6 GPM
- Rated life of about 6 months or 200 gallons, depending on water use and quality
- Installation type: push-button / twist-in, tool-free
A generic cartridge can copy the orange-accented shape and the push-button fit. What it cannot copy is the certification printed against this part number — and certification is the part that describes what is actually removed from the water. Our dedicated Filter 2 guide digs into the full compatibility and part-number picture for this cartridge.
How to Replace a KAD2RXD1 / EDR2RXD1
- Open the filter compartment in the upper-right interior of the fridge and press the eject/release — the old cartridge pops partway out.
- Pull it straight out. A few drops of water are normal; a towel on the shelf below keeps it tidy.
- Remove the new cartridge’s protective cap, align it with the housing, and push firmly, turning clockwise until it clicks into place.
- Flush 2–3 gallons through the dispenser and discard them, plus the first batch of ice — this clears trapped air and loose carbon.
- Reset the filter indicator on the control panel using your model’s method, and note the date. A new cartridge never resets the light by itself.
The whole job is tool-free and takes minutes. If the new cartridge will not click, do not force it: pull it back out and compare it side by side with the old one. A mismatch means the label test caught a different filter number — which is exactly what it is for.
KAD2RXD1 vs the Other KitchenAid Numbers
Because the KAD naming runs parallel to the EveryDrop numbering, KitchenAid owners sometimes order by brand alone and land on the wrong cartridge. The short map: KAD1RXD1 is Filter 1 — an internal twist-in cartridge serving mainly side-by-side models — while KAD2RXD1 is Filter 2, the push-button cartridge in the upper-right interior of French door models like the KRMF and KRFC families. The two housings are physically different and the cartridges do not interchange, which is why the digit after “KAD” matters as much as the prefix. If your old cartridge’s label is worn unreadable, identify the housing instead — push-button upper-right interior means Filter 2 — and let the shape settle what the label no longer can. The Filter 2 guide walks through that identification in full.
What a Genuine KAD2RXD1 Should Cost
Same cartridge, same price as every genuine EveryDrop filter in the range: $39.99 one-time at Discounted Filter Store, with free US shipping on any order amount — the product page shows $39.99–$147.99 across the pack sizes, with multi-packs lowering the per-filter price. The comparison that matters: the official EveryDrop store charges $59.99 one-time for the same cartridge, or $48 only with a subscription commitment; Filters Fast ships free only at $99+ and Discount Filter at $70+.
Orders are processed within 1–2 business days and delivered in 3–5 business days via USPS, and unopened filters can be returned within 30 days, free, with a prepaid label. Ready when you are: order the genuine EDR2RXD1 (Filter 2) — and if the number on your old cartridge is one you do not recognise, send it to us first and we will confirm the match before you spend anything.
Frequently Asked Questions
Are KAD2RXD1, P9WB2L and EDR2RXD1 really the same filter? Yes — three names for one cartridge. EDR2RXD1 is the current EveryDrop part number; KAD2RXD1 and P9WB2L are the KitchenAid-branded names, both listed on the product page alongside the older Whirlpool numbers W10413645 and W10413645A and Kenmore 46-9082.
Which KitchenAid models take the KAD2RXD1 / Filter 2? Mainly French door models with the push-button housing in the upper-right interior — the KRMF and KRFC families are the common ones. Confirm with the label on your old cartridge; it outranks any model list, including ours.
How often does Filter 2 need changing? About every 6 months or 200 gallons, per the product page, depending on water use and quality. Change sooner if the dispenser flow slows or taste and odour creep back.
Is the EDR2RXD1 NSF certified? Yes. Its specification lists NSF/ANSI Standards 42, 53 and 401 plus CSA B483.1, and its contaminants field states certified reduction of 99% of microplastics.
My KitchenAid’s filter is in the base grille, not the upper-right interior. Is it still Filter 2? Probably not — a base-grille housing usually means Filter 3 or Filter 4. Read the old cartridge’s label and match its number; our KitchenAid guide maps each housing to its filter.
How much is the genuine filter here, and how fast is delivery? $39.99 one-time for a single cartridge (packs to $147.99), free US shipping on any amount, processed in 1–2 business days and delivered in 3–5 business days via USPS, with free 30-day returns on unopened filters.
