If your Maytag fridge uses a UKF8001 filter, the replacement you need is sold under a second name too: EveryDrop Filter 4, part number EDR4RXD1. Same filter, same fit — the UKF8001 number is simply the Maytag branding for it. This guide covers how to confirm the match, how to swap it, how to reset the light, what to check before you order, and what to do when something goes wrong.
Confirm UKF8001 is really your filter
Do not order by fridge brand alone. Maytag has used several filter types over the years, so confirm one of these:
- The part number printed on your old cartridge — look for UKF8001 or EDR4RXD1.
- Your fridge’s manual or the filter housing label inside the fridge.
- The model number on the rating plate inside the fresh-food compartment, matched against the filter guide for that model.
If your cartridge says a different number, stop and match that number instead — a filter that looks right but is not your part number will not seal properly.
What EDR4RXD1 fits
EDR4RXD1 (Filter 4) is the EveryDrop cartridge for the Maytag UKF8001 fitment, and it also appears under the Whirlpool UKF8001 name. It is a push-in cartridge: no tools, no water shut-off in most installations, and the swap takes a few minutes. The full step-by-step is in our How to Replace EDR4RXD1 (UKF8001) Filter 4 walkthrough, and the UKF8001-to-EDR4RXD1 cross-reference is explained in UKF8001 Replacement EDR4RXD1.
How to swap it
- Open the filter housing (usually inside the fridge, upper right, or in the base grille depending on model).
- Twist or push-release the old cartridge as your housing directs, and pull it out.
- Push the new EDR4RXD1 in until it locks — a cartridge a quarter-turn short is the most common cause of slow flow after a change.
- Flush several gallons through the dispenser to clear carbon fines, then reset the filter indicator if your model has one.
If flow is slow or the water looks cloudy after the swap, check seating first before assuming the cartridge is faulty — it almost never is.
How to reset the Maytag filter light
Fitting a new filter does not clear the light on its own — the indicator is a reminder clock, not a sensor. Resetting is the last step of a filter change, never a substitute for one: fit the new filter fully, flush as directed, and close the fridge door — many panels ignore presses made with the door open. Then, on most Maytag models, find the button labelled “Filter Reset” or “Water Filter” (on some models it sits inside the interior controls rather than on the dispenser) and press and hold it for a full 3 seconds — count it out slowly, because a quick tap does nothing on these panels. The full walkthrough is in our Maytag filter light reset guide.
Genuine vs compatible: why the part number matters
Cheap compatible cartridges sometimes list UKF8001 compatibility without matching the original’s internal fit. A poor seal can leak, bypass filtration, or restrict flow. Buying the genuine EDR4RXD1 by its exact part number removes that gamble, and our Complete EveryDrop Buying Guide lists every EveryDrop number in one table if your fridge takes a different filter.
The honest price picture: the rival store’s Tier1 comparable for EDR4/UKF8001 is $25.94, and its genuine EDR4 is $55.44. Tier1 is a compatible, not the genuine cartridge — it is cheaper because it is not the original. Our genuine EDR4RXD1 is $39.99 with free US shipping, so genuine here costs less than genuine there, and a single filter ships free here while the rival’s free shipping starts only over $75.
Need the filter itself? Shop the genuine EveryDrop EDR4RXD1 (Filter 4) — $39.99 with free US shipping and 30-day free returns, against $59.99 at the official store.
A note on other Maytag numbers
Some Maytag models use other filter numbers entirely. If your cartridge or manual names a number other than UKF8001/EDR4RXD1, match that number exactly rather than ordering Filter 4 and hoping. The model number on your fridge is the final word.
If something is wrong after the change
- Slow flow: the cartridge is usually not fully seated and locked. Push until it locks, then flush again.
- Cloudy water: flush several gallons. Carbon fines clear with flushing and are not a fault.
- Light still on: the reset step above was missed or did not take. Re-seat the cartridge, close the door, then hold the reset button for a full 3 seconds.
FAQ
Is UKF8001 the same as EDR4RXD1?
Yes. UKF8001 is the Maytag-branded part number for the filter sold as EveryDrop Filter 4 (EDR4RXD1). They are the same cartridge and fit the same housings.
How often should I replace a UKF8001 filter?
About every 6 months, or sooner if flow slows, taste changes, or the indicator light comes on. Time matters as much as gallons: a filter left in for a year is spent even if use was light.
Do I need tools to replace it?
No. It is a push-in cartridge. Open the housing, release the old one, push the new one until it locks, flush, and reset the indicator.
My new filter is in but the water is slow. What is wrong?
First re-check that the cartridge is fully seated and locked, then flush again. A quarter-turn short is the most common cause of slow flow after a change.
