How To Change Pur Water Filter In Whirlpool Refrigerator

ByJim Boslice Home & Kitchen

To change a PUR-style water filter in your Whirlpool refrigerator, locate the filter housing either in the bottom base grille or the upper interior corner. Press the release button or twist the cartridge a quarter-turn counter-clockwise to remove it, then slide the new filter in until it clicks firmly into place.

Once installed, always flush four gallons of water through the system to remove air and carbon fines, then reset your “Filter Status” indicator light on the control panel.

We all rely on our refrigerators to provide crisp, clean water at the touch of a button, but that convenience depends entirely on a clean filter. Over time, sediment and minerals clog the internal membranes, slowing your water flow and affecting the taste of your ice. Learning how to change pur water filter in whirlpool refrigerator units is a basic DIY task that ensures your family stays hydrated with the highest quality water possible.

I promise that you don’t need a professional plumber or a toolbox full of specialized gear to get this job done right. Most Whirlpool models are designed for quick, tool-free maintenance that takes less than five minutes of your time. By following a few simple steps, you can prevent leaks and keep your appliance running efficiently for years to come.

In this guide, I will walk you through identifying your specific filter location, the step-by-step removal and installation process, and how to troubleshoot common issues like air pockets or stubborn indicator lights. Whether your filter is hidden in the base grille or tucked inside the fridge, you’ll have the confidence to handle it like a pro. Let’s get to work and get that water flowing clear again.

Identifying Your Whirlpool Filter Type and Location

Before you grab your towels and start pulling parts, you need to know exactly what you are looking for. Whirlpool has used several variations of the PUR filtration system over the years, though many have now transitioned to the EveryDrop brand. These filters are typically found in one of two places: the bottom base grille or the interior upper right-hand corner.

The base grille filter is common in side-by-side models and usually features a push-button release or a cap that requires a quarter-turn. If you don’t see a cylinder sticking out of the bottom of your fridge, look inside. Interior filters are often hidden behind a small “trap door” or are exposed in the back corner, requiring a simple twist to unlock.

Check your old filter for a part number, such as Filter 1, 2, 3, or 4. Having the correct part number is vital because these cartridges are not universal. Using the wrong model can lead to a poor seal, which is the primary cause of slow leaks that can damage your kitchen flooring over time.

The Importance of Genuine Replacement Filters

It is tempting to buy the cheapest generic filter you find online, but I always recommend sticking with OEM (Original Equipment Manufacturer) parts. Genuine Whirlpool or EveryDrop filters are certified to reduce specific contaminants like lead, pesticides, and pharmaceuticals. Generic versions often only focus on removing the taste of chlorine, leaving other particles behind.

Furthermore, the sealing rings on off-brand filters are often slightly off-spec. In my experience, a fraction of a millimeter difference in an O-ring can be the difference between a dry floor and a midnight flood. Spending a few extra dollars on a certified PUR-style filter provides peace of mind and protects your appliance warranty.

Essential Tools and Preparation

While you won’t need a pipe wrench, a little preparation goes a long way in preventing a mess. Even though these systems have auto-shutoff valves, a small amount of “residual water” will always escape when the seal is broken. I recommend keeping a thick shop towel or a small tray handy to catch any drips.

If your filter is located in the base grille, you might want to give that area a quick vacuum first. Dust and pet hair love to collect around the condenser coils and the filter housing. Cleaning this area while you are down there helps your refrigerator breathe easier and run more efficiently, which is a classic “Jim BoSlice” pro-tip for home maintenance.

Finally, ensure you have clear access to the area. If your fridge is tucked into a tight cabinet, you may need to open the doors fully to reach the interior housing. For base grille filters, make sure there isn’t a rug or floor mat blocking the ejector button. Once you have your towel and your new filter ready, you are set to begin the swap.

The process of how to change pur water filter in whirlpool refrigerator units depends on whether your model uses a push-button system or a twist-and-lock mechanism. For base grille models with a button, simply press the button located next to the filter cap. The filter should pop out about an inch, allowing you to grasp the cap and pull it straight out toward you.

Once the old filter is out, slide the decorative cap off the end of the old cartridge and snap it onto your new one. Don’t throw that cap away, as new filters usually don’t come with a replacement. Align the new filter so the ridges match the housing, and push it in firmly until the ejector button clicks back into its original position. You should feel a positive “thud” when it seats correctly.

For interior filters with a flip-up door, open the small compartment and pull the filter downward or outward. Some models require a quarter-turn counter-clockwise. When installing the new one, remove the protective red or blue plastic covers from the O-rings. Align the arrow on the filter with the housing, push it in, and turn it clockwise until it stops. Close the compartment door to lock it in place.

Handling a Stuck Filter

Occasionally, mineral buildup or internal pressure can make a filter difficult to remove. If the button won’t budge, try pressing inward on the filter cartridge while simultaneously pushing the release button. This often relieves the pressure on the locking “dogs” and allows the mechanism to fire. Never use pliers to force the plastic housing, as you risk cracking the manifold.

If you have an interior twist-style filter that feels stuck, try turning the water supply off for a moment and dispensing a bit of water to relieve line pressure. This makes the cartridge much easier to rotate. Once the old filter is out, wipe the inside of the housing with a clean cloth to remove any grit before sliding the new one home.

Flushing the System After Installation

Installing the filter is only half the battle; you must flush the system before drinking the water. New filters contain compressed carbon blocks. During shipping, small particles of carbon (known as “fines”) can break loose. If you don’t flush the line, your first few glasses of water will look cloudy or even black, and the water may have a metallic taste.

Place a large pitcher under the dispenser and run the water for four gallons. I usually suggest a “30 seconds on, 30 seconds off” cycle to prevent the dispenser solenoid from overheating. This process also clears out any air pockets trapped in the lines. If you hear a “sputtering” or “banging” sound while flushing, don’t worry—that is just air escaping the system.

Flushing also helps the filter fully saturate, which ensures it can properly catch contaminants. Once the water runs crystal clear and the flow is steady without sputtering, your filter is ready for use. You can use the flushed water to water your garden or indoor plants so it doesn’t go to waste.

Resetting the Filter Status Light

Your Whirlpool refrigerator doesn’t actually “sense” how dirty the filter is. Instead, it uses a simple timer that usually triggers every six months or after a certain number of gallons have passed through the valve. After you finish the physical installation, the “Change Filter” light will likely stay red or orange until you manually reset it.

Locate the Filter Reset button on your control panel. On most models, you need to press and hold this button for three to five seconds. You will usually hear a beep or see the light flash and turn green (or disappear). If your fridge has a “Touch Screen” or “Options” menu, you may need to navigate to the “Water Filter” section and select “Reset” from the digital display.

If you have an older model without a dedicated button, try pressing the Light and Ice Type buttons simultaneously for three seconds. Keeping this light accurate is the best way to ensure you never forget this vital maintenance task. If the light won’t reset, double-check that the filter is pushed in all the way, as some models have a small switch that must be engaged by the filter body.

Maintaining Optimal Water Quality

To keep your water tasting its best, you should aim to replace your filter every six months. However, if you have a large family that uses the dispenser constantly, or if you live in an area with very “hard” water, you might need to swap it every four months. A noticeable drop in water pressure is usually the first sign that the carbon block is reaching its capacity.

Another “pro” move is to check the O-rings on the filter before installation. If they look dry, you can apply a tiny, paper-thin smear of food-grade silicone grease to the rubber. This ensures a perfect seal and makes the filter much easier to remove six months down the line. Avoid using petroleum jelly, as it can degrade the rubber over time.

Finally, don’t forget the ice maker! The same filter feeds your ice tray. If your ice cubes start looking small, cloudy, or begin to clump together, it’s a strong indicator that the filter is restricted. Regular replacement ensures your ice remains clear and free of “freezer odors” that can be absorbed from the air if the water isn’t filtered properly.

Frequently Asked Questions About how to change pur water filter in whirlpool refrigerator

How do I know which PUR filter is compatible with my Whirlpool?

The easiest way is to look at the part number printed on the old filter. Whirlpool refrigerators typically use EveryDrop Filters 1 through 5. You can also find the specific model number on a sticker inside the refrigerator door and look it up on the Whirlpool website or the “The Jim BoSlice Workshop” archives.

Why is my water dispenser slow after changing the filter?

A slow flow usually means there is trapped air in the line or the filter isn’t fully seated. Try removing the filter and re-inserting it firmly. Then, run at least two to three gallons of water to purge any air pockets that might be causing a “vapor lock” in the system.

Can I just leave the old filter in if I don’t use the water?

It is not recommended to leave an old, expired filter in the fridge. Over time, the organic material trapped in the filter can grow bacteria or mold. If you don’t plan on using the dispenser, it is better to remove the filter and install a “bypass plug,” which allows water to flow to the ice maker without passing through a dirty filter.

Is it normal for the new filter to make a noise?

Yes, it is common to hear chirping or knocking sounds immediately after installation. This is simply the sound of air being pushed out of the carbon block and replaced by water. These noises should disappear completely after you have flushed the recommended four gallons of water.

Why does my water taste like plastic after the change?

This usually happens if the system wasn’t flushed sufficiently. The “plastic” or “chemical” taste is often just air and loose carbon particles. Run another gallon of water through the dispenser. If the taste persists, ensure you used a genuine OEM filter, as some low-quality knock-offs use inferior materials that can leach tastes into the water.

Final Thoughts on Refrigerator Maintenance

Taking the time to learn how to change pur water filter in whirlpool refrigerator units is a small investment that pays off in every glass of water you drink. It protects your family from contaminants and keeps your expensive appliance running without unnecessary strain. In the world of DIY, it’s these simple, recurring tasks that build the foundation of a well-maintained home.

Remember, the key to success is using the right part and being patient during the flushing process. Don’t be intimidated by the buttons or the twist-locks; these systems are built for homeowners just like you. Once you’ve done it once, you’ll be the go-to expert in your house for keeping the “refreshment center” in top-tier shape.

Stay proactive with your workshop and home repairs, and don’t let the small things slide. A clean filter today means better-tasting coffee, clearer ice, and a healthier household tomorrow. Now, grab that pitcher, reset that light, and enjoy a cold, clean glass of water—you’ve earned it!
