What Is the EDR4RXD1 / UKF8001 Filter?

The EDR4RXD1 (EveryDrop Filter 4, widely cataloged under legacy part number UKF8001) is Whirlpool Corporation's high-efficiency water filtration cartridge engineered with an advanced activated carbon block core. Certified to NSF/ANSI Standards 42, 53, and 401, it is designed to capture and neutralize potentially harmful impurities—including 99% of lead, microbial cysts, pesticides, pharmaceuticals, turbidity, and foul chlorine odors.

Featuring an engineered quarter-turn twist-and-lock neck design with dual sealing O-rings, this cartridge seats securely inside the filter housing, preventing internal water leaks, bypass contamination, and hydraulic pressure loss in the ice maker line.

How to Identify if Your Refrigerator Uses Filter 4

4-Step Identification Guide

  1. Locate the Data Plate: Find the white or silver sticker on the upper interior sidewall or behind the crisper drawer to obtain your complete refrigerator model number.
  2. Examine the Installed Filter: Remove the current cartridge and inspect the printed label. Look specifically for the "Filter 4" badge, part number EDR4RXD1, or UKF8001.
  3. Inspect the Housing Receptacle: Filter 4 features a cylindrical compartment located in the upper right interior ceiling corner or inside the fresh food compartment that operates via a quarter-turn rotation.
  4. Cross-Reference with Support Tools: Search your appliance model number on Smartfiltersusa to verify direct compatibility before ordering.

Installation and Replacement Guide

Step-by-Step Installation Process

Step 1: Locate the Housing — The compartment is typically positioned in the upper right interior ceiling of the refrigerator compartment or recessed within the interior wall.

Step 2: Release the Old Filter — Grasp the cartridge firmly, rotate it counterclockwise approximately 90 degrees (quarter turn) until it unlocks, and pull it straight out of the housing.

Step 3: Unpack the New EDR4RXD1 — Remove all protective caps and packaging. Inspect the dual black O-rings at the neck to ensure they are seated cleanly in their tracks.

Step 4: Insert and Engage — Align the alignment tabs with the housing grooves, push the cartridge inward, and rotate clockwise 90 degrees until it locks securely into place.

Step 5: Purge & Flush the System — Dispense 2 to 3 gallons (approx. 3 to 4 minutes) of water through the door dispenser to clear trapped air pockets and initial loose carbon fines.

Step 6: Reset Filter Indicator — Press and hold the Filter Reset or Water Filter button on the control panel for 3 seconds until the status indicator light returns to blue/green.

Frequently Asked Questions About EDR4RXD1

1. Are EDR4RXD1 and UKF8001 the exact same filter?

Yes. EDR4RXD1 is EveryDrop's modern retail packaging code, while UKF8001 is the legacy engineering part number utilized across Whirlpool and Maytag lines. Both designate the identical Filter 4 replacement cartridge.

2. Can I use Filter 1, 2, or 3 if my fridge requires Filter 4?

No. Each EveryDrop series (Filter 1, Filter 2, Filter 3, Filter 4, Filter 5) uses unique alignment tabs, housing diameters, and locking mechanisms. They are physically not cross-compatible.

3. How often should I replace my Whirlpool Filter 4 cartridge?

Whirlpool and NSF guidelines recommend replacing your EDR4RXD1 filter every 6 months or 200–300 gallons, or sooner if water pressure noticeably declines.

4. Is it safe to drink water if the filter is overdue for replacement?

While municipal water remains chemically treated, an expired carbon filter becomes saturated, allowing heavy metals, chlorine byproducts, and trapped particulates to pass into your drinking water and ice supply.

5. Can I clean and reuse my EDR4RXD1 / UKF8001 water filter?

No. The dense internal carbon block permanently absorbs microscopic contaminants within its porous structure and cannot be backwashed or regenerated. It must be replaced.

6. What contaminants does EveryDrop Filter 4 reduce?

It is certified under NSF 42, 53, and 401 to reduce 28 contaminants, including 99% of lead, mercury, asbestos, pesticides, microbial cysts, and foul chlorine taste and odor.

7. What should I do if the new filter causes a knocking noise or low water flow?

Knocking or sputtering indicates trapped air pockets within the water line. Running 2 to 3 gallons of water continuously through the dispenser purges the system and restores steady pressure.

8. Where can I buy genuine and certified EDR4RXD1 / UKF8001 filters?

You can purchase genuine, factory-tested replacement filters directly through Smartfiltersusa with guaranteed model compatibility and fast delivery.
