Whirlpool Refrigerator Water Filter Replacement: EDR1RXD1, EDR2RXD1, and EDR3RXD1 Guide for 2026
Whirlpool produces some of the most widely installed refrigerator water filters in residential use, both under the Whirlpool name and through its sister brands Maytag, KitchenAid, JennAir, and Amana. If you have a Whirlpool-family refrigerator with an in-door or in-cabinet water dispenser, your replacement filter is almost certainly an EveryDrop cartridge or a legacy Whirlpool part number. Picking the right one once means easy reorders for years.
This guide breaks down the current EveryDrop refrigerator filter lineup, the legacy Whirlpool part numbers still in active use, which refrigerators take which cartridge, and how subscribe-and-save scheduling solves the most common Whirlpool owner pain point: running out at the worst possible time.
The Whirlpool Refrigerator Filter Lineup
Whirlpool consolidated its refrigerator filter brand under EveryDrop several years ago. The EveryDrop cartridges are NSF-certified to 42, 53, and 401 and fit Whirlpool, Maytag, KitchenAid, JennAir, and Amana refrigerators across multiple generations.
| EveryDrop Cartridge | Legacy Part Numbers | Fits |
|---|---|---|
| EDR1RXD1 (Filter 1) | W10295370A, W10295370 | Most French-door models, current production |
| EDR2RXD1 (Filter 2) | W10413645A, 9082 | Most side-by-side and compact French-door |
| EDR3RXD1 (Filter 3) | 4396841, 4396710 | Specific French-door models |
| EDR4RXD1 (Filter 4) | 4396395, 4396510 | Older bottom-freezer models |
| EDR5RXD1 (Filter 5) | 4396508, 4396510 | Specific side-by-side models |
If you currently use a 4396701, 4396841, or 4396710 cartridge, you have a legacy Whirlpool part number that corresponds to a current EveryDrop replacement. The legacy parts remain in production for the large installed base of older Whirlpool refrigerators, and the EveryDrop equivalents fit the same housings.
How to Identify Your Whirlpool Cartridge
The most reliable verification, in order of confidence:
- Read the part number on the existing filter. Pull the current cartridge out and look for the alphanumeric code printed on the body. Match that number to the lineup table above.
- Check the refrigerator manual. Most Whirlpool manuals list the cartridge part number in the maintenance section.
- Refrigerator model number lookup. The inside-door sticker has the refrigerator's model number. Whirlpool's compatibility lookup matches model to cartridge.
- Cabinet inspection. Some Whirlpool refrigerators have the cartridge part number printed inside the housing.
If you have run through all four and still cannot identify the cartridge, our support team can verify by refrigerator model number before you order. Call 855-789-3278 or email info@poseidonfilters.com.
EDR1RXD1 (Filter 1): The Current French-Door Standard
The EDR1RXD1 is the most commonly ordered Whirlpool refrigerator cartridge. It fits the majority of current-production Whirlpool, Maytag, KitchenAid, JennAir, and Amana French-door refrigerators.
Quick Specs
| Spec | Value |
|---|---|
| EveryDrop number | EDR1RXD1 (Filter 1) |
| Legacy equivalents | W10295370A, W10295370 |
| Capacity | 200 gallons |
| Replacement interval | 6 months or 200 gallons |
| Connection | Push-and-twist quick change |
| Certifications | NSF/ANSI 42, 53, and 401 |
What the EDR1RXD1 Removes
The full NSF 42/53/401 certification profile covers:
- Lead and mercury (NSF 53)
- Cysts including Cryptosporidium and Giardia (NSF 53)
- Asbestos (NSF 53)
- Chlorine taste and odor (NSF 42)
- Particulates Class I (NSF 42)
- Pharmaceuticals including ibuprofen, naproxen, atenolol (NSF 401)
- Pesticides and endocrine disruptors (NSF 401)
- Industrial compounds (NSF 401)
For health-conscious households, the NSF 401 certification is the meaningful differentiator. It is the same testing standard used on premium drinking-water systems applied to a refrigerator cartridge.
EDR2RXD1 (Filter 2) and EDR3RXD1 (Filter 3)
The EDR2RXD1 fits most Whirlpool side-by-side refrigerators and select compact French-door models. The EDR3RXD1 fits specific French-door models that did not transition to the EDR1RXD1 platform.
Both cartridges carry the same NSF 42/53/401 certifications and the same 6-month replacement interval. The difference is the housing geometry and the refrigerator model they fit.
If your existing cartridge is a 4396841, 4396710, or 4396710p, you most likely need the EDR3RXD1. If your existing cartridge is a 9082 or has "Filter 2" stamped on the body, you need the EDR2RXD1. The cartridge label is the verification source.
Legacy Whirlpool Cartridges: 4396701, 4396841, 4396710
Whirlpool continues to produce legacy part numbers for the older refrigerator generations that did not transition to the EveryDrop platform. These cartridges remain widely available:
- 4396701 fits older Whirlpool side-by-side and French-door models from approximately 2005-2015
- 4396841 fits specific Whirlpool French-door models and corresponds to the current EDR3RXD1
- 4396710 fits Whirlpool refrigerators using the same housing as the 4396841
If your existing cartridge carries one of these legacy part numbers, you can order the same legacy part for direct replacement, or in many cases the current EveryDrop equivalent will fit the same housing. For Whirlpool refrigerators built before 2015, sticking with the matching legacy part number is the safest approach.
How to Replace a Whirlpool Refrigerator Filter
The replacement procedure is similar across all Whirlpool cartridge types. Total time is under two minutes plus a flush.
- Locate the cartridge. Whirlpool refrigerators position the filter in one of three places: inside the fresh-food compartment (upper-right or upper-left corner), behind a bottom-grille panel at floor level, or behind a small swing-out door near the dispenser.
- Turn the existing cartridge counter-clockwise approximately a quarter turn. You will feel it release from the housing.
- Pull the cartridge straight out. A small amount of water will drip. Have a paper towel ready.
- Remove the new cartridge from packaging. Pull off the protective cap and avoid touching the O-ring with bare hands.
- Insert the new cartridge into the housing with the orientation matching the housing slot. Push gently and rotate clockwise a quarter turn until the cartridge locks.
- Reset the filter indicator by holding the appropriate reset button on the control panel for 3 to 5 seconds. The procedure varies by refrigerator model.
- Flush the new cartridge by dispensing approximately 2 gallons of water before drinking. The first cup or two may appear cloudy from carbon fines. The cloudiness clears within a minute.
When to Replace a Whirlpool Filter
Whirlpool specifies replacement every 6 months or 200 gallons of filtered water, whichever comes first. The 6-month calendar interval is the binding constraint for most households.
The refrigerator's "Replace Filter" indicator is calendar-based. It triggers at the 6-month mark regardless of actual water usage. Heavy filtered-water households may benefit from replacing before the indicator triggers to maintain peak contaminant reduction.
Signs the cartridge is past due:
- Replace Filter indicator on the control panel
- Reduced flow from the water dispenser
- Returning chlorine taste in filtered water
- Slower ice production
- Cloudy water that does not clear within a minute
Subscribe and Save: Built for the 6-Month Cycle
The Whirlpool refrigerator filter cycle aligns perfectly with subscription delivery. Every 6 months, a fresh cartridge arrives a few days before the install date, with email reminders if you want them. You skip, pause, or cancel any shipment without penalty.
For households running multi-refrigerator setups (a primary kitchen refrigerator plus a garage or basement unit), the subscription model is even more valuable. Two cartridges on a coordinated 6-month schedule means neither refrigerator ever runs past the replacement interval.
The subscribe-and-save discount applies to every cartridge in the Whirlpool refrigerator lineup, including EDR1RXD1, EDR2RXD1, EDR3RXD1, and the legacy 4396 series.
Authentic vs Aftermarket Whirlpool Filters
The genuine Whirlpool and EveryDrop cartridges are NSF-certified to the standards listed on the packaging. Aftermarket "Whirlpool-compatible" cartridges fit the same housings and produce water but vary in NSF certification and carbon density.
Things to verify on any aftermarket cartridge:
- NSF certification numbers printed on the packaging
- O-ring fit matches the original housing dimensions
- Carbon density matches the original specification
- Manufacturer reputation for consistent quality
The price difference between authentic Whirlpool/EveryDrop and aftermarket is usually small enough that the OEM cartridge is the right choice. The aftermarket gamble on a $30-40 cartridge is not worth a potential leak or a cartridge that fails to deliver NSF 401-grade filtration.

Frequently Asked Questions
What is the difference between EDR1RXD1 and EDR3RXD1?
The EDR1RXD1 fits most current-production Whirlpool French-door refrigerators. The EDR3RXD1 fits specific French-door models that use a different housing geometry. The cartridge label on your existing filter is the safest source for which one you need.
Is the EDR1RXD1 the same as the W10295370A?
Yes. EDR1RXD1 is the current EveryDrop part number. W10295370A is the legacy Whirlpool manufacturing number. Same physical cartridge.
Can I use an EveryDrop cartridge in a Maytag or KitchenAid refrigerator?
Yes. EveryDrop is the consolidated filter brand for Whirlpool's corporate family, which includes Maytag, KitchenAid, JennAir, and Amana. The cartridges are designed to fit refrigerators across all five brands.
Why does my Whirlpool refrigerator say "Replace Filter" when I just installed a new cartridge?
The indicator is calendar-based and needs to be reset after installation. Hold the filter reset button on the control panel for 3 to 5 seconds.
Does the EDR1RXD1 remove fluoride?
No. The EDR1RXD1 removes lead, mercury, chlorine, cysts, pharmaceuticals, and pesticides. Fluoride removal requires a reverse osmosis system.
Can I subscribe to a multi-refrigerator household plan?
Yes. Subscriptions can be set up per refrigerator with coordinated delivery dates. Multi-cartridge subscriptions also stack the subscribe-and-save discount across all cartridges in the subscription.
Will the 4396701 fit my newer Whirlpool refrigerator?
The 4396701 fits older Whirlpool refrigerators (approximately 2005-2015). Newer Whirlpool French-door models use the EDR1RXD1, EDR2RXD1, or EDR3RXD1. The cartridge label on your existing filter is the verification source.
