Understanding the Whirlpool Filter 4: Model Numbers Explained
The Whirlpool Filter 4 is a premium water filtration system designed to provide clean, fresh drinking water and ice for your Whirlpool refrigerator. However, this single filter is marketed under several different model numbers, which can create confusion for consumers. Understanding these designations is crucial for purchasing the correct replacement filter.
The primary model numbers you'll encounter are:
- UKF8001: The most common designation, used in numerous Whirlpool refrigerator models
- EDR4RXD1: An alternative model number for the same filter technology, often used in specific refrigerator series
- Whirlpool 4396701: An older designation that appears in legacy models and some regional markets
These filters all use identical filtration technology and are NSF certified to meet strict water quality standards. The difference in model numbers primarily reflects manufacturing batches, regional distribution, and compatibility with specific refrigerator generations.
The Whirlpool Filter 4 utilizes advanced multi-stage activated carbon filtration to remove chlorine, sediment, volatile organic compounds, and other contaminants that affect water taste and odor. Each filter is designed to process approximately 200 gallons of water or last six months, whichever comes first.
Compatibility Guide for Whirlpool Refrigerator Models
Before purchasing a replacement filter, it's essential to verify that the UKF8001, EDR4RXD1, or Whirlpool 4396701 is compatible with your specific refrigerator model. Using an incompatible filter can result in poor water quality, leaks, or system malfunctions.
To find your refrigerator's model number, look for the nameplate typically located on the side wall inside your refrigerator or on the back of the unit. Your refrigerator's user manual will also contain this information.
| Refrigerator Type | Compatible Models | Filter Type |

| Older/Legacy Models | Various models from 2010-2015 | Whirlpool 4396701 |
Pro tip: Always verify your refrigerator model number before purchasing a replacement filter. You can usually find this information on a sticker inside your fridge or in the user manual.

Step-by-Step Installation Process for the Whirlpool Filter 4
Installing the Whirlpool Filter 4 (UKF8001/EDR4RXD1) is straightforward and requires minimal tools. Follow these detailed steps to ensure proper installation and optimal filter performance.
Preparation: What You'll Need
Before beginning the installation process, gather the following items:
- Your new Whirlpool Filter 4 (UKF8001, EDR4RXD1, or 4396701)
- A clean towel or small container to catch any water spillage
- Your refrigerator's user manual (optional but helpful)
- A flashlight (helpful for locating the filter housing)
Step 1: Locate Your Filter Housing
The filter housing location varies depending on your refrigerator model. Common locations include:
- Inside the refrigerator: Upper right wall (most common)
- Inside the refrigerator: Lower right wall or bottom corner
- Base grille: At the bottom front of the refrigerator
- Behind the refrigerator: Less common but possible in some models
Step 2: Turn Off the Water Supply (Recommended)
While not always mandatory, turning off the water supply to your refrigerator is highly recommended to prevent water spillage during filter replacement. Locate the water shut-off valve behind your refrigerator and turn it clockwise to close it.
Step 3: Remove the Old Filter
The method for removing your old filter depends on your refrigerator's design. You'll encounter one of these mechanisms:
- Twist-lock design: Rotate the filter housing counterclockwise until it stops, then pull it straight out toward you.
- Push-release design: Press the filter housing inward, and it should pop out with a spring mechanism.
- Screw-in design: Unscrew the filter housing from the bracket by turning counterclockwise.
Step 4: Prepare Your New Filter
Remove your new Whirlpool Filter 4 from its packaging. Some filters come with protective caps or seals that must be removed before installation. Check the filter's instruction sheet for any specific preparation requirements.
Step 5: Install the New Filter
Insert the new filter into the housing, aligning it properly with the connection points. Depending on your refrigerator model:
- Twist-lock: Rotate the filter clockwise until it's snug and secure.
- Push-release: Push the filter straight into the housing until you hear a distinct click.
- Screw-in: Tighten the filter housing onto the bracket by turning clockwise until snug.
Step 6: Restore Water Supply and Flush
If you turned off the water supply, turn it back on. Run water through the dispenser for 3-5 minutes to flush out any air and carbon dust from the new filter. The water may appear slightly discolored initially—this is completely normal and will clear after flushing.
Step 7: Reset the Filter Indicator Light
Many Whirlpool refrigerators feature a filter indicator light that alerts you when replacement is needed. Hold the reset button for 3-5 seconds or follow your model's specific menu options to clear the warning.

Maintenance and Care Guidelines for Optimal Performance
Proper maintenance ensures your Whirlpool Filter 4 performs at its best and lasts its full lifespan. Follow these guidelines to maximize filter effectiveness:
Regular System Flushing
After initial installation, continue flushing the water dispenser occasionally—at least once weekly—to maintain water quality and remove any accumulated particles.
Monitor the Filter Indicator Light
Pay close attention to your refrigerator's filter indicator light. When it activates or changes color, replace the filter promptly.
Track Replacement Dates
Write the installation date directly on your new filter using a permanent marker. This simple practice helps you remember when replacement is due.
| Maintenance Task | Frequency | Duration/Notes |
|---|---|---|
| Flush water dispenser | Weekly | Run for 1-2 minutes |
| Check filter indicator | Monthly | Replace when activated |
| Replace filter | Every 6 months | Or after 200 gallons |
| Inspect for leaks | After installation & quarterly | Check connections |
| Clean housing area | Every 3 months | Wipe with damp cloth |
Troubleshooting Common Issues and Solutions
Even with proper installation and maintenance, you may occasionally encounter issues with your Whirlpool Filter 4. Here are solutions to common problems:
Water Tastes or Smells Bad After Filter Installation
If your water still has an unpleasant taste or odor after installing a new filter, the filter may not be properly seated. Remove the filter and reinstall it. If the problem persists, the filter may be defective.
Water Dispenser Not Dispensing Water
A non-functioning water dispenser could indicate a clogged filter or air trapped in the water line. Try flushing the system for 5-10 minutes to remove air and clear blockages.
Water Leaking from Filter Housing
Leaks typically indicate the filter isn't properly seated or the housing is damaged. Turn off the water supply, remove the filter, and inspect the housing for cracks before reinstalling.
Ice Maker Producing Cloudy or Discolored Ice
Cloudy ice often results from air in the water line or a new filter that hasn't been properly flushed. Run water through the dispenser for several minutes to remove air and carbon particles.
