Our verdict on the Whirlpool Refrigerator Filter 4 (EDR4RXD1)
As checked 2026-09-15, Whirlpool's Refrigerator Filter 4 (sold as EDR4RXD1 under the everydrop brand and as WHR4RXD1 under the Whirlpool brand, the identical NSF-listed filtration system used in host systems W11256135 and W11311161) is listed live in NSF's directory under NSF/ANSI 42, 53, and 401. It is a twist-in, point-of-use refrigerator cartridge for potable municipal or well water within 30-120 psi and 33-100°F, rated for six months or up to 200 gallons, and is not for microbiologically unsafe or unknown-quality water without adequate disinfection.[1][2][3][4]
Best for
- Point-of-use refrigerator filtration on potable municipal or well water within 30-120 psi and 33-100°F.
- Households of about 3-4 people replacing the cartridge on the manufacturer's recommended six-month cadence.
Not for
- Microbiologically unsafe or unknown-quality water without adequate disinfection before or after the system.
- Refrigerators that call for a different Everydrop or Whirlpool filter number than Filter 4 -- the manufacturer instructs shoppers to match the exact number and brand of their existing filter rather than assume interchangeability.

The Whirlpool Refrigerator Filter 4 (EDR4RXD1) against its family and its rivals
The Whirlpool Refrigerator Filter 4 (EDR4RXD1) has 2 siblings in its family: EDR1RXD1 (Filter 1), EDR2RXD1 (Filter 2).
The rest of the family
| Model | What differs |
|---|---|
| EDR1RXD1 (Filter 1) | A different, separately NSF-listed cartridge for a different refrigerator platform; not interchangeable with Filter 4. |
| EDR2RXD1 (Filter 2) | A different, separately NSF-listed cartridge (P9WB2L system, 0.60 gpm) for a different refrigerator platform; not interchangeable with Filter 4. |
The Whirlpool Refrigerator Filter 4 (EDR4RXD1) and cartridges sold as compatible
The live NSF listing checked 2026-09-15 shows both certified host systems, W11256135 and W11311161, sharing one replacement-element group of seven names -- EDR4RXD1, EDR4RXD1B, EDR4RXD1R, KAD4XD1, WHR4RXD1, Kenmore 9084, and W10790818 -- all carrying the identical 34-claim set (3 under NSF/ANSI 42, 17 under NSF/ANSI 53, 14 under NSF/ANSI 401). This record makes no certification claim for third-party cartridges marketed as compatible with Filter 4, including cartridges sold against the unrelated “UKF8001” cross-reference number. A live UKF8001 search on the same date returns separate listings from three manufacturers, none of them Whirlpool Corporation: Ecolife Technologies, Inc. and Pacific Citadel Capital, Inc. each carry only the two NSF/ANSI 42 claims (Chlorine Reduction, Taste and Odor Reduction), while Qingdao Ecopure Filter Co., Ltd.'s private-label rows (AQUA CREST, Amazon Basics, Maxblue, Overbest, Waterdrop) additionally carry up to 6 NSF/ANSI 53 claims and 6 NSF/ANSI 401 claims -- a maximum of 14 claims per model, still well short of the genuine element's 34. Any such cartridge's own directory listing would require independent verification.[1][2]

Whirlpool Refrigerator Filter 4 (EDR4RXD1) questions, answered
How do I replace a Whirlpool water filter 4?
Open the filter compartment inside the refrigerator, turn the old EDR4RXD1/WHR4RXD1 cartridge counterclockwise and pull it out, remove the cap from the new cartridge, insert it and turn clockwise until it locks, then flush the dispenser. No tool is required.
Sources: [1]
What is the number 4 fridge water filter?
It is Whirlpool's Filter 4, sold as EDR4RXD1 under the everydrop brand and as WHR4RXD1 under the Whirlpool brand -- the identical NSF-listed twist-in cartridge for the certified host systems W11256135 (rated 100 gallons without a Performance Indicator Device) and W11311161 (rated 200 gallons with one). It is distinct from Whirlpool's other numbered filters (1, 2, 3, 5, 6, A), which are separately NSF-listed for different refrigerator platforms.
Sources: [1]
Can I use a generic water filter in my Whirlpool refrigerator?
Verified health claim
A third-party cartridge marketed as compatible may physically fit, but this record's certification claims cover only the OEM element listed by NSF under EDR4RXD1, EDR4RXD1B, EDR4RXD1R, KAD4XD1, WHR4RXD1, Kenmore 9084, and W10790818. A generic or aftermarket cartridge carries no certification claim here; it would need its own dated NSF, IAPMO R&T, or WQA listing to support the same contaminant-reduction claims, and Whirlpool's own materials say non-genuine filters may cause damage to the appliance.
What happens if you don't change the refrigerator water filter on schedule?
Verified health claim
Whirlpool's performance data sheet says the cartridge must be changed at least every six months (or by its rated 100-200 gallon capacity) for the product “to perform as advertised,” and warns that property damage can occur if replacement requirements are not followed. Running it past that interval or its rated capacity is outside the tested basis for the NSF/ANSI 42, 53, and 401 claims above.
Sources: [1]
Is the Whirlpool refrigerator water filter 4 NSF certified?
Verified health claim
Yes. As of a live check on 2026-09-15, NSF's directory lists this element -- EDR4RXD1, EDR4RXD1B, EDR4RXD1R, KAD4XD1, WHR4RXD1, Kenmore 9084, and W10790818 -- under host systems W11256135 and W11311161 for NSF/ANSI 42 (chlorine, particulate, taste/odor), NSF/ANSI 53 (lead and 16 other named contaminants), and NSF/ANSI 401 (microplastics and 13 other named contaminants). No listing was found in the IAPMO R&T or WQA directories on the same date, which is a fact about those two directories' corpus rather than evidence the product is uncertified elsewhere.
Sources: [1]
What is the difference between the Whirlpool EDR4RXD1 and WHR4RXD1 water filter?
They are the identical NSF-listed filtration system sold under two brand names by the same manufacturer: EDR4RXD1 is the everydrop-branded listing and WHR4RXD1 is the Whirlpool-branded listing, and NSF's live directory lists both part numbers under the same host systems with the same claim sets. As checked 2026-09-15, both were priced at $59.99 list / $48.00 sale on whirlpool.com, but EDR4RXD1 carried a 4.5-star rating from 1,220 reviews on that site versus WHR4RXD1's 4.0 stars from 180 reviews, and the two pages' Specifications tabs give slightly different weight and width figures (2.5 in / 0.75 lb for EDR4RXD1 versus 3 in / 0.77 lb for WHR4RXD1).
Is the Whirlpool EDR4RXD1 filter the same as a UKF8001 filter?
Verified health claim
No. UKF8001 is a separate, generic cross-reference number that multiple unrelated manufacturers list their own aftermarket cartridges against; NSF's live directory shows UKF8001 filters listed by three manufacturers, none of them Whirlpool Corporation. Two of those rows (Ecolife Technologies, Inc. and Pacific Citadel Capital, Inc.) carry only the two NSF/ANSI 42 claims (chlorine and taste/odor reduction); the third, Qingdao Ecopure Filter Co., Ltd., lists a set of private-label brands (AQUA CREST, Amazon Basics, Maxblue, Overbest, Waterdrop) that additionally carry NSF/ANSI 53 and 401 claims, for a maximum of 14 claims per model -- still well short of the genuine EDR4RXD1/WHR4RXD1 listing's 34 claims across the same three standards.
Sources and data report: Whirlpool Refrigerator Filter 4 (EDR4RXD1)
Every figure above is taken from the highest-trust source that carries it and re-derived from that source by a separate check. How we verify product data.
What we could not establish, and why
| Field | Why it is blank |
|---|---|
| identity.upc | The everydrop and Whirlpool-branded product pages, the performance data sheet, and the exact Amazon landing page were checked, but none exposed a carton UPC that could be verified as this single EDR4RXD1 cartridge. |
| identity.capacity | The live NSF listing and the manufacturer's performance data sheet both give a host-dependent rated capacity -- 100 gallons for host system W11256135 (no Performance Indicator Device) and 200 gallons for W11311161 (with one) -- so the schema's single unconditional capacity value cannot preserve the published condition honestly. |
| certified.certIndexKey | The repository certification index (apps/website/data/certifications/by-brand/whirlpool-corporation.json) has entries keyed by the SYSTEM model numbers W11256135 and W11311161, each with an empty model_aliases array -- it does not carry EDR4RXD1, WHR4RXD1, or any other Filter 4 part number as a join key, unlike the filter-numbered keys (e.g. EDR2RXD1B) found for the Filter 2 family. Neither system entry alone would represent the sold filter without fabricating the missing alias link, so no index key was selected. |
| mechanism.treatmentMethods | The manufacturer describes a coconut-shell activated-carbon core with three marketing-named stages (“large-particle filtration, medium-size micro-filtration, and targeted microscopic absorption”), but those stage names do not map unambiguously onto the schema's closed treatment-method vocabulary without approximating a slug. |
| install.estimatedHours | The brand page states replacement takes “under 5 minutes,” which is an upper bound, not a point value; the schema's SourcedQuantity accepts only a single amount, and converting “under 5 minutes” to exactly 5 minutes would overstate the source's precision. |
| install.manual | The everydrop and Whirlpool-branded product pages' only “Additional Documents” link is the performance data sheet, which itself directs installation questions to the refrigerator's own Owner's Manual rather than providing a standalone EDR4RXD1/WHR4RXD1 installation manual; only the official video was found. |
| fit.bathroomsServed | Bathroom sizing does not apply to a refrigerator cartridge, and none of the reviewed sources publish a bathroom range for it. |
| fit.roOutputGpd | EDR4RXD1/WHR4RXD1 is not a reverse-osmosis membrane; the performance data sheet publishes a service flow rate, not an RO output figure. |
| fit.roTankCapacity | This is a refrigerator cartridge with no RO storage tank; no tank capacity is published for it. |
| fit.connectionSize | The brand pages, performance data sheet, and install video describe a twist-in cartridge interface but publish no nominal connection diameter. |
| fit.requiresElectricity | The cartridge's own installation materials describe no independent electrical connection, but none of the reviewed sources states an explicit electricity requirement (or its absence) as a boolean fact about the cartridge itself, so none was inferred. |
| fit.requiresDrain | The cartridge's own installation materials describe no drain connection, but none of the reviewed sources states an explicit drain requirement (or its absence) as a boolean fact about the cartridge itself, so none was inferred. |
| cost.wasteRatio | EDR4RXD1/WHR4RXD1 is not an RO membrane, and its performance data sheet publishes no waste-to-product water ratio. |
| cost.warranty | The performance data sheet's warranty note refers readers to the refrigerator's own Owner's Manual/User Guide warranty section rather than stating a cartridge-specific warranty term; no filter-specific warranty was found. |
| cost.moneyBackGuarantee | The reviewed pages show only a general 30-day return window, not a product-specific money-back or satisfaction guarantee for this cartridge: Amazon's listing for ASIN B00UB38V2A states “FREE 30-day refund/replacement,” and whirlpool.com/return-policy.html gives parts and accessories 30 days from the date of shipment under its parts-and-accessories heading -- separate from the 15-day window that same page states applies to major-appliance returns. |
| seo.verification | The independent verify loop has not run yet; it is responsible for stamping this field after independent re-derivation. |
