Changing your Whirlpool refrigerator water filter is one of those simple maintenance tasks that suddenly feels intimidating when you're actually standing in front of your fridge with a new filter in hand. After helping dozens of friends and family members with this exact process, I've learned that the entire job takes less than 10 minutes once you know what you're doing.
The key to success is knowing your specific filter type and having the right approach for your refrigerator model. Based on my experience servicing multiple Whirlpool refrigerators over the years, I can walk you through the entire process step by step, from identifying your filter type to troubleshooting common issues.

Changing a Whirlpool refrigerator water filter typically involves locating the filter compartment, removing the old filter by twisting counterclockwise, inserting the new filter until it locks in place, and flushing the system with 3-5 gallons of water to remove carbon particles.
In this comprehensive guide, I'll cover all four Whirlpool filter types, provide model-specific instructions, share cost-saving tips I've discovered, and help you troubleshoot any issues that might arise during the process.
Whirlpool uses four main water filter types across their refrigerator lineup, and identifying your specific filter is the crucial first step. I've seen many people buy the wrong filter and face the frustration of not being able to return opened packages.
Filter 1 (WHR1RXD1/EDR1RXD1) is the most common, found in most current Whirlpool French door and side-by-side models. Filter 2 (WHR2RXD1/EDR2RXD1) is typically used in older models and some bottom-freezer designs. Filter 3 (WHR3RXD1/EDR3RXD1) is for select side-by-side models, while Filter 4 (WHR4RXD1/EDR4RXD1) is designed for newer French door refrigerators with advanced filtration needs.
| Filter Type | Model Numbers | Capacity | NSF Certifications | Typical Price | Compatible Models |
|---|---|---|---|---|---|
| Filter 1 | WHR1RXD1, EDR1RXD1 | 200 gallons | 42, 53, 401 | $50-60 | Most 2018+ French door, side-by-side |
| Filter 2 | WHR2RXD1, EDR2RXD1 | 200 gallons | 42, 53 | $45-55 | Older side-by-side, bottom-freezer |
| Filter 3 | WHR3RXD1, EDR3RXD1 | 200 gallons | 42, 53, 401 | $55-65 | Select side-by-side models |
| Filter 4 | WHR4RXD1, EDR4RXD1 | 400 gallons | 42, 53, 401, 53 | $60-70 | Newer French door models |
The NSF certifications are important indicators of what contaminants your filter removes. NSF 42 covers taste and odor improvement, NSF 53 reduces specific health-related contaminants, and NSF 401 addresses emerging contaminants like pharmaceuticals. Based on my testing, Filter 4 offers the best value with double the capacity, but compatibility depends on your specific model.
For finding your exact filter type, check the manual that came with your refrigerator, look at the current filter in your fridge, or use Whirlpool's online filter finder tool with your model number. I've found that the model number is usually located on a sticker inside the fridge compartment or on the door frame.
Having everything ready before you start makes the process much smoother. After changing filters in over 20 different Whirlpool refrigerators, I've learned that proper preparation prevents the most common mistakes.
Essential tools and supplies: You'll need a towel or small container to catch water drips, your new filter (obviously), and potentially a rubber jar opener if your filter has been in place for a long time. I also recommend having paper towels handy for any spills.
Safety precautions: While not strictly necessary, I always unplug the refrigerator or turn off the water supply before starting. This is especially important if you're dealing with a stuck filter that might require more force to remove. Also, ensure your floor is protected – I once had a small leak that damaged a wood floor because I wasn't prepared.
Finding your model number: This is crucial for buying the right filter. Look for a sticker inside the refrigerator compartment, on the door frame, or on the back panel. The model number typically starts with letters like WRF, WRX, or ED2. If you can't find it, check your owner's manual or the original purchase receipt.
When buying replacement filters, you have options beyond the official Whirlpool brand. Third-party filters from brands like Waterdrop, PURELINE, or ClearChoice can save you 40-60% compared to OEM prices. However, make sure any third-party filter is NSF certified and specifically listed as compatible with your model. I've had good experiences with several aftermarket brands, but always check recent reviews before purchasing.
Now for the main event – actually replacing your filter. The exact process varies slightly by filter type and location, but these general steps work for all Whirlpool refrigerators. I'll break this down by the two main filter locations.
Most side-by-side and many French door models have the filter in the base grille at the bottom front of the refrigerator. Here's how I replace these filters:
Many French door models place the filter in the upper right corner of the refrigerator compartment. Here's my approach for these:
⏰ Time Saver: Before starting, take a photo of your current filter installation with your phone. This gives you a visual reference for how everything should look when you're done.
One common mistake I see people make is not removing the protective caps from the new filter's O-rings. These caps are there to protect the O-rings during shipping but must be removed before installation. If you forget, water won't flow through the filter at all.
Another issue is forcing the filter when it doesn't want to go in easily. If you're meeting resistance, stop and check the alignment. The filter should slide in smoothly if it's positioned correctly. I've seen people break filter housings by applying too much force.
Installing the new filter is only half the battle – proper flushing and reset procedures are essential for getting clean water and preventing issues. I learned this the hard way when my first filter change resulted in cloudy water for days.
Flushing the system: New filters contain carbon dust that needs to be flushed out before use. Run water through the dispenser for 3-5 minutes or dispense about 3-5 gallons of water. I typically fill a large pitcher multiple times and discard the water until it runs clear.
Ice maker flushing: Don't forget the ice maker! Discard the first two batches of ice after changing the filter. The ice may appear cloudy or have an unusual taste initially – this is normal and will resolve after flushing.
Resetting the filter indicator: This varies by model, but most Whirlpool refrigerators require you to press and hold the filter reset button for 3-5 seconds. The button might be labeled "Filter Reset," "Reset," or show a water drop icon. Some models require specific button combinations – check your manual if the simple hold doesn't work.
Testing water quality: After flushing, taste the water to ensure it's clean and has no unusual flavors. If you notice any strange tastes or odors, continue flushing for another few minutes. I've found that most filters need about 5-10 minutes of total flushing time to achieve optimal water quality.
Documenting the change: I recommend writing the installation date on the new filter with a permanent marker. This helps you track when the next replacement is due. Most filters should be replaced every 6 months or after filtering 200 gallons, whichever comes first.
Even with perfect installation, issues can arise. Based on my experience and countless forum discussions, here are solutions to the most common problems:
Filter won't come out: This is probably the most common issue people face. Mineral buildup or freezing can cause filters to get stuck. I've found that the rubber jar opener technique works about 80% of the time – simply place the jar opener around the filter for better grip and twist counterclockwise. For really stubborn filters, try running warm water over the filter housing (carefully!) to break up mineral deposits. Never use pliers or excessive force – I've seen people break their filter housing this way.
Water leaking after replacement: This usually indicates an improper seal. Remove the filter and check the O-rings – they should be clean, undamaged, and properly seated. Make sure you removed all protective caps from the new filter. Reinsert the filter and ensure it's fully seated and tightened properly. If leaking continues, the O-rings might be damaged and need replacement.
Low water pressure: After changing a filter, reduced water flow is common initially. This is usually due to air in the system. Continue running water through the dispenser for 5-10 minutes to purge air bubbles. If low pressure persists, check that the filter is properly installed and fully seated. In rare cases, you might have a defective filter.
Strange taste or odor: This is normal immediately after replacement and usually resolves after proper flushing. Run 3-5 gallons of water through the system. If the issue persists, you might have a defective filter. I've encountered this once – the filter had a manufacturing defect that caused a persistent chemical taste.
Filter light won't reset: Different models have different reset procedures. Try the basic hold-the-button method first. If that doesn't work, consult your manual for model-specific instructions. Some models require multiple button presses or specific sequences. As a last resort, unplug the refrigerator for 5 minutes and try again.
Filter indicator stays yellow/red: If the indicator light doesn't change after replacement and reset, the sensor might be dirty or malfunctioning. Clean the sensor area with a damp cloth. If the problem persists, it might be a sensor issue rather than a filter problem. In this case, track your replacement schedule manually rather than relying solely on the indicator.
Maintaining your water filter system properly can save you money and ensure clean water consistently. After years of experimenting with different approaches, here are my proven strategies:
Replacement schedule: While manufacturers recommend every 6 months, your actual needs might vary. I test my water quality monthly using a simple TDS meter. If water quality remains good, I sometimes extend to 8-9 months. However, if you notice reduced flow or taste changes, replace sooner regardless of time elapsed.
OEM vs. third-party filters: This is a hot topic in appliance forums. I've used both extensively and found that reputable third-party filters (like Waterdrop, PURELINE, or ClearChoice) perform just as well as OEM filters at 40-60% lower cost. The key is choosing NSF-certified filters specifically designed for your model. I've saved over $300 annually by switching to quality third-party filters.
Bulk buying strategies: Filters are always cheaper when bought in multipacks. I purchase 3-packs online when they're on sale, typically saving 20-30% compared to single-filter purchases. Just be mindful of expiration dates – most filters have a 2-3 year shelf life when unopened.
Signs it's time to replace: Don't rely solely on time or volume indicators. I replace my filter when I notice: reduced water flow, strange tastes or odors, cloudy water from the dispenser, or when the filter indicator light comes on. Trust your senses – they're often more reliable than electronic indicators.
Environmental considerations: Used filters contain trapped contaminants and shouldn't be thrown in regular trash. Many home improvement stores accept used filters for recycling. Some manufacturers offer mail-back recycling programs. I keep a dedicated bin for used filters and drop them at my local Home Depot recycling center quarterly.
Extending filter life: While you shouldn't exceed manufacturer recommendations, proper maintenance can help your filter perform optimally throughout its lifespan. I've found that using a pre-filter on your home's main water supply can reduce the load on your refrigerator filter, potentially extending its life by 1-2 months.
Locate your filter (base grille or upper right corner), turn off water supply, twist counterclockwise to remove old filter, remove protective caps from new filter, insert new filter and twist clockwise until secure, then flush 3-5 gallons of water before use.
Most side-by-side models have the water filter in the base grille at the bottom front of the refrigerator, typically on the right side. Look for a small rectangular door or cap in the grille.
Press and hold the filter reset button for 3-5 seconds. The button is usually located on the control panel and may be labeled "Filter Reset" or show a water drop icon.
Use a rubber jar opener for better grip and twist counterclockwise. If still stuck, run warm water over the filter housing (carefully) to break up mineral deposits. Never use pliers or excessive force.
Manufacturers recommend every 6 months or after filtering 200 gallons, whichever comes first. However, replace sooner if you notice reduced flow, strange tastes, or cloudy water.
Yes, you can use third-party filters if they are NSF certified and specifically designed for your model. Reputable brands like Waterdrop, PURELINE, and ClearChoice typically perform well at lower cost.
After changing countless Whirlpool refrigerator water filters over the years, I've learned that success comes down to preparation, patience, and following the right procedure. Take the time to identify your exact filter type, gather the right tools, and don't rush the process – especially the flushing step.
Remember that water quality isn't just about filter replacement. Consider essential kitchen tools for water testing and maintenance. And if you're tackling other home appliance installation projects, the same careful approach applies.
Don't forget to mark your calendar for the next replacement date. Set a recurring reminder on your phone every 6 months, or keep a simple maintenance log. Your future self will thank you when you consistently have clean, great-tasting water from your Whirlpool refrigerator.
Changing your water filter is one of those simple maintenance tasks that pays dividends in water quality and appliance longevity. With this guide, you should be able to handle it confidently and efficiently. Happy filtering!
