A cloudy glass from the fridge dispenser can make a simple refill feel uncertain. The right replacement cartridge restores that everyday convenience, but model compatibility matters more than packaging claims. These options cover common Maytag, Whirlpool, Kenmore, EveryDrop, Samsung, and Frigidaire filter families, with packs ranging from two to three cartridges.

More Details On Our Top Picks
The Filters Fast PH21500 earns its place through broad compatibility across several filter families used by Maytag, Whirlpool, Kenmore, and Frigidaire refrigerators. Its activated carbon block is designed to reduce fine sediment and odor, which matters in a busy kitchen where a dispenser serves cold water and ice throughout the day.
The listed flow rate is 0.5 gallons per minute, and the manufacturer recommends replacement every six months or after 300 gallons. That schedule gives you a practical routine rather than an open-ended guess, although actual timing varies with household use.
What Stands Out
- Works with EveryDrop EDR4RXD1, Maytag UKF8001, and numerous Whirlpool, Kenmore, and Frigidaire models.
- Activated carbon media targets fine particles and odors that can affect dispenser water.
- The 0.5 GPM flow rate suits routine refrigerator dispensing.
- A clear six-month or 300-gallon replacement guidance helps prevent long overdue changes.
Points To Note
- Model numbers still need to be checked because “Filter 4” descriptions can cover several related cartridge shapes.
- Filter changes require access to the housing and the appliance’s specified replacement procedure.
Key Specs
Who It Suits Best
You benefit most when your refrigerator uses a listed Filter 4 or UKF8001-style cartridge and you want one replacement that spans several compatible brands.
Consider Something Else When
Filterlogic UKF8001 EveryDrop Filter 4 Water Filter 3-Pack suits households wanting three cartridges and an expanded compatibility list.
For a Kenmore refrigerator that takes the 46-9910 cartridge, this two-pack keeps a second filter within reach before the next routine change. That practical reserve is the central appeal, especially for a household that does not want to remember the replacement part number at the last minute.
The cartridge also replaces the 1CB filter, giving you another model reference to compare with the housing. The information here is intentionally narrow, so matching the number printed on the existing cartridge remains essential.
What Makes Sense
- The two-pack supports consecutive maintenance changes.
- Direct compatibility references include Kenmore 46-9910 and 1CB cartridges.
- Keeping a spare is useful in homes where the dispenser receives frequent use.
Practical Considerations
- This choice is tied to a specific cartridge family rather than broad Filter 4 compatibility.
- Two cartridges still require adequate storage space away from moisture and heat.
Feature Snapshot
Made For
You get the most benefit if your Kenmore uses the 46-9910 or 1CB cartridge and you prefer stocking replacements in pairs.
Not Your Match When
Waterdrop EDR3RXD1 EveryDrop Filter 3 Water Filter 3-Pack is the better fit for an EveryDrop Filter 3 refrigerator.
Filterlogic’s three-pack extends beyond a single refrigerator brand, which makes it useful in homes with more than one compatible appliance. It covers UKF8001, EveryDrop Filter 4, EDR4RXD1, EDR4RXD2, Whirlpool 4396395, several UKF8001AXX numbers, and Kenmore 46-9006 references.
Its coconut-shell carbon block is the feature that matters for a dispenser used for drinking water and ice. Compared with the Filters Fast PH21500, this option offers a larger stated model network and a third cartridge, but your appliance still needs to appear in the compatible list.
What Earns Its Place
- A three-pack reduces the chance of running out during a scheduled change.
- Compatibility spans Maytag, Whirlpool, EveryDrop, Amana, Kenmore, and other listed models.
- Coconut-shell carbon media targets chlorine taste and odor.
- One cartridge family can cover appliances in different rooms.
Trade Offs
- The long compatibility list requires careful reading against your refrigerator model.
- Storing three cartridges takes more space than keeping a single replacement.
- The pack does not serve Filter 3 refrigerators.
Right Fit For
You benefit most with several Filter 4-compatible refrigerators or a household that prefers a three-change reserve.
A Better Fit Elsewhere
Filters Fast PH21500 EveryDrop EDR4RXD1 Filter 4 offers a single option with a stated 0.5 GPM flow rate and six-month replacement guidance.
The WSM-2 targets a familiar cluster of Maytag, Whirlpool, and Kenmore cartridges. Its compatibility references include Maytag UKF8001, UKF8001AXX, several 6700-series numbers, Whirlpool Filter 4, 4396395, and Kenmore 46-9005 and 46-9992.
A carbon block handles taste and odor reduction at the dispenser, while the three-pack supports a steady replacement rhythm. Unlike the more expansive Filterlogic model, WaterSentinel narrows the focus to a related but more defined set of cartridge references.
Features That Help
- Supports numerous Maytag UKF8001 and related model numbers.
- Includes Whirlpool Filter 4 and 4396395 compatibility.
- Carbon block media suits routine chlorine taste and odor reduction.
- Three cartridges suit households replacing filters on a regular schedule.
Worth Noting
- Compatibility still depends on the exact number inside or beside the filter housing.
- The three-pack requires more shelf space than a one-cartridge purchase.
At A Glance
Built With In Mind
You benefit most with a Maytag or Whirlpool refrigerator whose cartridge number appears in the listed fit references.
Another Choice May Suit
Filterlogic UKF8001 EveryDrop Filter 4 Water Filter 3-Pack fits shoppers whose refrigerators include broader EDR4 and UKF8001AXX references.
The two-pack version of Filterlogic’s UKF8001 cartridge offers a middle ground between a single replacement and the larger three-pack. It makes sense for households that want a spare without committing extra storage space, especially when the dispenser is used every day for cooking and drinking.
This filter is built around UKF8001 and EveryDrop Filter 4 applications, with compatibility also associated with Whirlpool 4396395 and related refrigerator cartridges. The coconut-shell carbon block focuses on reducing chlorine taste and odor.
Key Advantages
- Two cartridges cover the current change and one future replacement.
- Supports UKF8001, EveryDrop Filter 4, and Whirlpool 4396395 applications.
- Coconut-shell carbon block addresses common taste and odor concerns.
Small Caveats
- It does not suit refrigerators requiring EveryDrop Filter 3 cartridges.
- Two-pack buyers need a dry place to store the unused cartridge.
The Right Fit
You benefit most with a UKF8001 or Filter 4 refrigerator and a preference for maintaining one spare.
Reach For A Different Pick When
PUREPLUS RWF4200A Samsung DA97-17376B Water Filter 2-Pack is the stronger choice for a compatible Samsung refrigerator.
Waterdrop’s EDR3RXD1 cartridge is aimed at a different refrigerator family from the Filter 4 options above, so the model number is the decisive detail. It fits EveryDrop Filter 3 applications and the associated 4396841 cartridge reference.
The filter is listed to NSF/ANSI 42 for chlorine reduction and NSF/ANSI 372 for lead-free material requirements. A carbon-style refrigerator cartridge, three-pack format makes this a sensible routine option for a home dispensing cold water and making ice every day.
What Works In Its Favor
- Directly addresses EveryDrop Filter 3 and 4396841 refrigerator cartridges.
- Listed to NSF/ANSI 42 for chlorine reduction.
- NSF/ANSI 372 applies to the lead-free material requirement.
- Three cartridges provide a useful replacement reserve.
Details To Watch
- Filter 3 and Filter 4 cartridges are not interchangeable in these refrigerator systems.
- The unused cartridges need dry, protected storage.
Quick Facts
Whose Shelf It Belongs On
You benefit most with an EveryDrop Filter 3 refrigerator and enough storage room for three replacement cartridges.
Look Elsewhere When
Filters Fast PH21500 EveryDrop EDR4RXD1 Filter 4 fits refrigerators that specifically use the EDR4RXD1 or UKF8001 families.
Samsung households need a cartridge that matches a different naming system from the EveryDrop and UKF8001 choices. The PUREPLUS RWF4200A centers on Samsung DA97-17376B and also lists DA97-08006C, HAF-QIN, HAF-QIN/EXP, and WS645 applications.
Its two-cartridge format leaves a spare for the next service point, while the listed NSF/ANSI 42 and NSF/ANSI/CAN 372 standards provide useful material and chlorine-reduction context. Compared with the three-pack options, it offers a more compact reserve for a compatible Samsung setup.
Positive Points
- Targets the widely used Samsung DA97-17376B cartridge.
- Supports several additional Samsung filter references.
- Listed to NSF/ANSI 42 for chlorine reduction.
- Two filters provide a compact maintenance reserve.
The Fine Print
- Samsung model references do not translate to EveryDrop or UKF8001 cartridges.
- Check the housing and existing cartridge before ordering.
Quick Technical Notes
Best Suited To
You benefit most with a Samsung refrigerator matching DA97-17376B or one of the listed HAF-QIN and WS645 references.
Swap It Out When
Upstart Battery Kenmore 46-9910 Water Filter 2-Pack is the better fit for a Kenmore refrigerator using the 46-9910 or 1CB cartridge.
Start With the Cartridge Number on Your Refrigerator
The cartridge number matters more than the brand on the box. Locate the filter inside the housing or check the refrigerator documentation, then compare that number with the product’s fit list. A filter that looks similar can still be wrong for the housing, especially within broad Filter 4 families.
Check the Full Model Reference
Part numbers and refrigerator model numbers serve different purposes, so verify both where the listing provides them. Filters Fast PH21500, for example, supports EDR4RXD1 and UKF8001 applications, while the PUREPLUS RWF4200A focuses on Samsung references. This prevents a costly mismatch caused by a familiar-looking cartridge.
Choose the Pack Size Around Your Storage Space
A two-pack suits a household wanting one spare, while three packs reduce repeated ordering and work well across several compatible appliances. Store unused cartridges in their packaging somewhere dry and protected from temperature swings. Avoid choosing a larger pack simply to have more on hand.
Look at Filtration Media and Standards
Activated carbon block media is intended to reduce taste and odor associated with chlorine. NSF/ANSI 42 references relate to chlorine reduction, while NSF/ANSI 372 addresses lead-free material requirements. These standards help explain the cartridge’s purpose, but the appliance compatibility remains the deciding factor.
Follow a Consistent Replacement Routine
Your drinking volume, dispenser frequency, and household size determine when replacement becomes due. Filters Fast lists a six-month or 300-gallon guideline, which provides a useful reference alongside your refrigerator’s instructions. Set a calendar reminder so a tired-looking dispenser doesn’t become the deciding factor.
Avoiding the Wrong Refrigerator Filter
Common Shopping Slip Ups
A close visual match does not confirm compatibility. Compare the complete cartridge number, brand, and housing requirements, and never assume that Filter 3 and Filter 4 cartridges interchange. Also check the storage area before buying a three-pack, since extra cartridges still need a dry home.
What The Higher Tier Buys
Higher-tier refrigerator filters often emphasize filtration media, material standards, pack quantity, or a broader fit network. The premium cost can be reasonable when a household needs three cartridges or multiple compatible refrigerators, but model fit remains more important than added features.
Frequently Asked Questions
How do I know which fridge water filter I need?
Compare the cartridge number with the number printed on your current filter or listed in the refrigerator documentation. Match the complete reference rather than relying on the appliance brand alone.
Can I use a Filter 3 cartridge in a Filter 4 refrigerator?
No. Filter 3 and Filter 4 belong to different cartridge families, and their housing and fitting requirements are not interchangeable.
How often should I replace a refrigerator water filter?
Follow the appliance guidance and the cartridge manufacturer’s schedule. Filters Fast PH21500 lists six months or 300 gallons as its replacement guidance.
Is a three-pack more economical than a single filter?
It can be for households that use the dispenser regularly or maintain several compatible refrigerators. Compare the fit list, cartridge quantity, and storage space before deciding.
What does NSF/ANSI 42 mean for a refrigerator filter?
NSF/ANSI 42 applies to specific contaminant-reduction claims, including chlorine reduction for compatible products. It does not determine whether the cartridge fits your refrigerator.
Final Thoughts
Start with the cartridge number inside your refrigerator, then narrow the choice by filtration media, standards, and pack size. The Filters Fast PH21500 offers broad compatibility, the Filterlogic packs suit Filter 4 households, and the Waterdrop and PUREPLUS options serve more specialized cartridge families. A careful model check makes the replacement far simpler.
