EveryDrop EDR4RXD1 Replacement (2026): Which One to Buy
Guide
Your Whirlpool, Maytag, KitchenAid or Amana fridge is calling for an EDR4RXD1 — and the listings answer with three different part numbers and a price spread from $10 to $60. UKF8001, 4396395, EDR4RXD1: same filter or three different ones? And is the genuine EveryDrop worth roughly double a compatible?
Here is the short answer: the EDR4RXD1 is EveryDrop Filter 4, and UKF8001 and 4396395 are the same filter under its older numbers — those aliases are interchangeable. Whirlpool’s brand pages state NSF/ANSI 42, 53 and 401 certification including certified lead reduction, at 6 months or 200 gallons. Genuine runs roughly $90–120 a year; decent compatibles run under $40, with NSF/ANSI 42 paperwork at best. Buy genuine for the certification, a listed compatible for the savings — but buy the right number first.

Quick verdict
Buy the genuine EveryDrop EDR4RXD1 if you want the stated 42/53/401 certification with certified lead reduction — at roughly $45–60 a cartridge it is premium-priced, but it is the only tier whose paperwork covers lead. Buy a listed compatible (Waterdrop, ICEPURE, PUREPLUS) if your water is municipally treated and taste is the concern: under $40 a year is hard to argue with. Either way, the part-number maze is simpler than it looks — EDR4RXD1, UKF8001 and 4396395 are one filter, so shop all three numbers and take the best genuine price. Our EDR4RXD1 fit, reset and cost guide has the full install walkthrough.
First, confirm the EDR4RXD1 is your filter
Filter 4 serves a big family: Whirlpool, Maytag, KitchenAid and Amana French-door and side-by-side models, plus some Kenmore fridges built by Whirlpool. Depending on the model, the cartridge lives in a drop-down ceiling housing inside the fresh-food compartment or in the base grille. The part-number situation is the main trap, so here it is plainly:
| Part number | What it is |
|---|---|
| EDR4RXD1 | Current EveryDrop Filter 4 number |
| UKF8001 | The same filter under its older Maytag-era number |
| 4396395 | The same filter under its Whirlpool parts number |
| FILTER4 / Filter 4 | The family name all three numbers belong to |
Unlike some alias situations, these are genuinely the same cartridge — a replacement sold under any of them fits a Filter 4 housing. What you should not do is extend that logic to Filter 1, 2 or 3 numbers (EDR1RXD1 and family): different cartridges, different housings.
Your replacement options, compared
| Option | Price per filter | Price per year | Certification | Best for |
|---|---|---|---|---|
| Genuine EveryDrop EDR4RXD1 | ~$45–60 | ~$90–120 | NSF/ANSI 42, 53, 401 — stated on Whirlpool’s brand pages, incl. lead | Full certified claims |
| Listed compatible (Waterdrop, ICEPURE, PUREPLUS) | ~$15–20 | Under ~$40 | NSF/ANSI 42 listings at best — no 53/401 | Taste and odor on a budget |
| No-name multipack | ~$9–12 | ~$18–24 | Seller’s own claims only | Rock-bottom price, unverified claims |
At 200 gallons and a $50 genuine price, the genuine cartridge works out near $0.25 per gallon — the premium is visible but so is what buys it: the 53 listing is the lead claim, and compatibles leave it behind. The EDR4RXD1’s showing in our NSF 53 certified fridge filter roundup — best overall — rests on that same paperwork.
Check Current PriceWhat the genuine premium actually buys
Genuine EDR4RXD1 — pros
- Certified lead reduction — Whirlpool states NSF/ANSI 42, 53 and 401 certification for the genuine cartridge.
- One filter, three numbers — shop EDR4RXD1, UKF8001 and 4396395 listings and take the best genuine price.
- Exact quarter-turn fit — the cartridge the housing was built around; sealing is never in doubt.
Genuine EDR4RXD1 — cons
- The steepest yearly cost of the mainstream filters — roughly $90–120 a year.
- Counterfeits ride the aliases — a “genuine UKF8001” at $12 is neither genuine nor, usually, checked.
- Reset sequences vary by brand — Whirlpool, Maytag and KitchenAid panels do it differently.
As always, a compatible filter does not void your fridge warranty under the Magnuson-Moss Warranty Act — but the compatible’s certification ceiling (NSF/ANSI 42) means you are choosing taste-and-odor coverage and giving up the certified lead claim, knowingly.
Fitting your replacement
About two minutes, no tools: turn the old cartridge counterclockwise roughly a quarter-turn and pull it straight out (keep a towel handy — a little water spills), push the new cartridge in and turn clockwise until it stops, then flush about 2 gallons through the dispenser. The red light is a timer, not a sensor, and its reset sequence depends on your fridge’s brand — Whirlpool, Maytag and KitchenAid each use a different button combination. Our EDR4RXD1 guide lists them brand by brand, and our all-brands reset guide covers the rest of the family.
Conclusion
The EDR4RXD1 decision comes down to one question: do you need the lead claim? If yes, the genuine EveryDrop (roughly $45–60) is the only tier carrying the stated NSF/ANSI 53 certification — shop its three part numbers for the best genuine price. If your water concern is taste on a treated municipal supply, a listed compatible under $20 does the everyday job for a third of the yearly cost. Either way, change it at 6 months or 200 gallons, and treat the aliases as what they are: one filter, three labels.

FAQs
Is the UKF8001 the same filter as the EDR4RXD1?
Yes. UKF8001 is the older Maytag-era number for the same Filter 4 cartridge that EveryDrop now sells as the EDR4RXD1; 4396395 is its Whirlpool parts number. The three are interchangeable — a genuine cartridge under any of the numbers fits a Filter 4 housing.
Does the EDR4RXD1 remove lead?
Whirlpool’s brand pages state the genuine EDR4RXD1 is certified to NSF/ANSI 53, which includes lead reduction, alongside 42 (chlorine, taste and odor) and 401 (emerging contaminants). Compatible Filter 4 cartridges do not carry the 53 listing, so the certified lead claim belongs to the genuine cartridge.
Which fridge brands use the EDR4RXD1?
Whirlpool, Maytag, KitchenAid and Amana models that spec Filter 4 — mostly French-door and side-by-side fridges — plus some Kenmore models built by Whirlpool. Your manual’s filter specification or the number on the old cartridge is the deciding check.
How often do I replace the EDR4RXD1?
Every 6 months or 200 gallons, whichever comes first. The indicator light is a timer on that schedule rather than a sensor. Heavy ice and water use can exhaust the cartridge sooner; slowing flow is the signal to watch.
How do I reset the filter light after changing the EDR4RXD1?
It depends on the brand — Whirlpool, Maytag and KitchenAid panels each use a different button sequence, and changing the cartridge does not reset the light by itself. Our EDR4RXD1 fit and reset guide lists the sequence for each brand in the Filter 4 family.
Why is the genuine EDR4RXD1 so much more expensive than compatibles?
Mostly the certification and the brand channel. The genuine cartridge carries the stated NSF/ANSI 42, 53 and 401 paperwork — including the lead claim compatibles skip — and EveryDrop prices it as the premium option across four fridge brands. The practical premium is roughly $50–80 a year over a listed compatible.
