What Water Filter Does My Whirlpool Refrigerator Use

ByJim Boslice Home & Kitchen

Whirlpool refrigerators primarily use EveryDrop filters, categorized by numbers 1 through 5. To identify yours, locate the model number on the interior wall of your fridge or check the label of your current filter.

Most modern units use Filter 1 (top right interior) or Filter 4 (inside the door), while older models often use Filter 3 or Filter 5 located in the bottom base grille.

Finding the right parts for home appliances can feel like a scavenger hunt, especially when you are staring at a dozen identical-looking cartridges. If you’ve ever stood in the appliance aisle staring at a wall of blue and white boxes, you’ve likely asked yourself: what water filter does my whirlpool refrigerator use?

I’ve spent years in the workshop and maintaining properties, and I can tell you that getting the right filter the first time saves you from the headache of leaks and “parts-store-paralysis.” Whirlpool has streamlined their system significantly, but you still need to know exactly where to look to avoid a compatibility nightmare.

In this guide, I’m going to walk you through the simple steps to identify your filter, explain the EveryDrop numbering system, and show you how to swap it out like a pro. We will ensure your water stays clean and your workshop-fridge or kitchen-command-center remains leak-free.

Finding Your Refrigerator Model Number

The most reliable way to determine your filter type is by finding the model number of the refrigerator itself. Manufacturers hide these stickers in a few standard places, usually on the interior walls of the fresh food compartment.

Open your refrigerator doors and look at the upper right-hand side or the ceiling of the interior. If it isn’t there, check behind the crisper drawer or on the door frame. This sticker contains the model number (MOD) and serial number (SER) you need for a perfect match.

Once you have that number, you can enter it into the Whirlpool or EveryDrop website. However, for most DIYers, simply looking at the physical location of the existing filter is often the fastest way to narrow down the search.

Decoding the EveryDrop Numbering System

Whirlpool transitioned their filtration to the EveryDrop brand, which uses a simple 1 through 5 numbering system. Each number corresponds to a specific physical shape and connection mechanism. Filter 1 is perhaps the most common in modern French-door and side-by-side models. It is a long, slender cylinder that usually slides into a compartment in the top right corner of the refrigerator ceiling. Filter 2 is shorter and wider, often found in the same top-right location but in specific bottom-freezer models. Understanding these physical differences helps you visualize what water filter does my whirlpool refrigerator use before you even pull the old one out.

To answer this question definitively, you must look at the mounting location and the style of the cap. Whirlpool designs their units so that only the correct filter will “lock” into place, preventing accidental bypasses.

If your filter is located in the base grille at the bottom of the refrigerator, it is almost certainly a Filter 3 or a Filter 5. Filter 3 uses a push-button release, while Filter 5 requires a quarter-turn to unlock.

For those with the filter located inside the door or tucked into the interior housing, you are likely looking for a Filter 4. This filter has a unique “grab and pull” handle that makes it very distinct from the ceiling-mounted versions.

Always double-check the part number printed on the side of your old cartridge. Even if the branding has changed over the years, the cross-reference numbers will usually point you directly to the modern EveryDrop equivalent.

The Five Major EveryDrop Types

  • Filter 1 (EDR1RXD1): Fits most side-by-side and French door models; located in the top right ceiling.
  • Filter 2 (EDR2RXD1): Used in specific bottom-freezer models; also ceiling-mounted.
  • Filter 3 (EDR3RXD1): Found in the bottom base grille; uses a push-button release.
  • Filter 4 (EDR4RXD1): Common in newer French door models; located inside the door or top right.
  • Filter 5 (EDR5RXD1): Found in the base grille; uses a quarter-turn handle.

Step-by-Step Replacement Guide

Replacing the filter is a fundamental DIY task that requires no tools, but it does require a bit of finesse. Before you start, it is a good idea to turn off the ice maker to prevent it from cycling while the water pressure is fluctuating.

Locate the filter housing and open the cover. For ceiling-mounted filters, the door usually swings down. For grille-mounted filters, you might need to press a button or twist a cap 90 degrees counter-clockwise.

Pull the old filter straight out. You might notice a small amount of water dripping; this is normal and is just residual pressure in the line. Have a shop rag or paper towel handy to catch any stray drops.

Installing the New Filter

Remove the protective caps from the new filter. I always recommend checking the O-rings on the end of the filter. If they look dry, you can apply a tiny amount of food-grade silicone or even a drop of water to help them seat properly.

Align the filter with the arrows on the housing and push it in firmly. You should feel a positive click or a locking sensation. If you are using a twist-style filter, turn it clockwise until it stops—do not over-tighten or force it.

Once installed, close the housing door. If the door won’t close, the filter isn’t seated deeply enough. Knowing what water filter does my whirlpool refrigerator use is only half the battle; ensuring a watertight seal is the other half.

Flushing the System and Resetting the Light

After a fresh install, your water lines will contain trapped air and loose carbon dust from the new filter. If you try to drink the first glass, it will likely look grey and the dispenser will sputter aggressively.

Run at least three to four gallons of water through the dispenser. This “flushing” process clears out the carbon fines and ensures the air pockets are purged from the internal reservoir. It also allows you to check for any slow leaks around the filter head.

Once the water runs clear and steady, you need to reset the indicator light. Most Whirlpool models have a “Filter Reset” button on the control panel. Hold it down for three seconds until the light turns green or the “Replace” message disappears.

Dealing with a Stuck Filter

Sometimes, mineral buildup or water pressure can cause a filter to get stuck in the housing. If the push-button won’t release or the filter won’t budge, do not reach for a pair of heavy-duty pliers immediately.

Try turning off the main water supply to the fridge and dispensing a bit of water to relieve the internal pressure. Often, the pressure is what’s holding the locking tabs in place. Once the pressure is gone, the filter should pop out with a gentle tug.

If it is still stuck, a pair of slip-joint pliers can be used, but wrap the filter cap in a rag first. You want to apply steady, even pressure rather than jerking the plastic components, which can crack the manifold.

Why Genuine Filters Matter for DIYers

In the workshop, we often look for ways to save money on consumables. However, when it comes to what water filter does my whirlpool refrigerator use, I strongly suggest sticking with OEM (Original Equipment Manufacturer) EveryDrop filters.

Generic filters often lack the NSF certifications required to remove lead, pesticides, and pharmaceuticals. While they might fit the hole, the internal gaskets are often lower quality, which can lead to slow leaks that rot out your subfloor over time.

A genuine filter is designed to handle the specific PSI of your home’s plumbing. Spending an extra ten dollars on a certified filter is cheap insurance against a flooded kitchen and a ruined hardwood floor.

The Environmental Impact of Timely Replacement

Replacing your filter every six months isn’t just about taste; it’s about efficiency. A clogged filter forces the refrigerator’s internal valves to work harder, which can lead to premature wear on the solenoid.

By keeping the filtration system clean, you also reduce the need for bottled water. One EveryDrop filter can replace up to 1,500 plastic water bottles, making it a win for your wallet and the planet.

For those of us who spend all day in the garage or workshop, having crisp, clean water on tap is a necessity. Identifying what water filter does my whirlpool refrigerator use ensures that your hydration break is actually refreshing and free of contaminants.

Frequently Asked Questions About Whirlpool Water Filters

How often should I change my Whirlpool water filter?

You should change your filter every six months or after 200 gallons of use. If you notice the water flow slowing down or a change in taste or odor, it is time for a replacement, regardless of how long it has been installed.

Can I use my refrigerator without a water filter?

Yes, most Whirlpool models come with a filter bypass plug, or the housing itself has a built-in bypass. However, this means your water and ice will not be filtered. Never leave the filter housing empty without a bypass, as this can cause leaks.

Why is my new water filter making a loud noise?

A “banging” or “shaking” noise usually indicates trapped air in the lines. This is common immediately after installation. Continue flushing the dispenser for another gallon or two to purge the air, and the noise should stop.

How do I know if my filter is a counterfeit?

Counterfeit filters often have blurry printing on the labels, weigh significantly less than the original, and lack the holographic security stickers. To ensure you are getting the real deal, buy directly from reputable appliance parts retailers.

Final Thoughts on Whirlpool Filtration

Taking care of your home’s appliances is just like maintaining your power tools—it requires the right parts and a bit of preventative maintenance. Once you identify what water filter does my whirlpool refrigerator use, the actual replacement takes less than five minutes.

Remember to always flush the system and keep an eye on the O-rings during installation. Clean water is a small luxury that makes a big difference in your daily routine, whether you’re finishing a woodworking project or just cooling off after a long day of DIY repairs.

Stay proactive with your home maintenance, keep your model number handy, and don’t let a “Replace Filter” light stay red for too long. Your fridge—and your family—will thank you for the clean, clear results.
