Our verdict on the Frigidaire ULTRAWF
Frigidaire's ULTRAWF (PureSource Ultra) is the OEM push-to-lock cartridge for PureSource Ultra® and PureSource® 3 refrigerators manufactured by Frigidaire after 2009, rated 200 gallons or 6 months; as of 2026-09-11 IAPMO R&T lists it under NSF/ANSI 42, 53, 401 and 372, but NSF's own live directory carries no Frigidaire or Electrolux listing for it despite Frigidaire's own datasheet stating “NSF Certified: Yes.”[1][2][3][4][5]
Best for
- Owners of a Frigidaire refrigerator built for the PureSource Ultra or PureSource 3 filter housing, manufactured by Frigidaire after 2009.
- Buyers who specifically want IAPMO R&T's certified claims for this cartridge: lead, mercury, cysts, asbestos, VOCs (including MTBE and TTHM), and, under NSF/ANSI 401, atenolol, ibuprofen, trimethoprim and microplastics.
- Buyers who want a verified-genuine cartridge rather than one of the many third-party “ULTRAWF-compatible” cartridges NSF's own directory and a federal patent-infringement ruling both show exist.
Not for
- Refrigerators built for Frigidaire's newer PurePour filter system (FPPWFU01, FPPWFU02, WFPTU26) or the PureSource Ultra II system (EPTWFU01) — IAPMO R&T lists all four as separate models rated 125 gallons, versus ULTRAWF's own 200-gallon rating, each with its own reduction-claim set.
- Installations outside the rated 30–100 psi water pressure or 33–100°F water temperature range Frigidaire's own Performance Data Sheet specifies.

Which models the Frigidaire ULTRAWF fits
The Frigidaire ULTRAWF fits the one model listed below, verified 2026-09-11.[1]
| Model | Notes |
|---|---|
| Frigidaire refrigerators equipped with the PureSource Ultra® or PureSource® 3 filter housing, manufactured after 2009 | Frigidaire's own ULTRAWF Performance Data Sheet and Safety Information document both state: “Fits all PureSource Ultra® and PureSource® 3 models manufactured by Frigidaire after 2009,” and direct buyers to “See fits models listing on Frigidaire.com” for the itemized appliance list. frigidaire.com's own ULTRAWF product page could not be reached from this research environment — every attempt (rendered browser navigation and a raw HTTP fetch) failed with a connection-level error rather than a page-level one, even though the page is live and indexed by search engines — so no individual refrigerator model number could be independently verified here. |

What the Frigidaire ULTRAWF does not do
Frigidaire's own Performance Data Sheet warns buyers away from unverified third-party cartridges: “Know for certain your filter is a protector. Counterfeits and knockoffs put fridges and health at risk.” NSF's live directory separately lists 30 third-party “ULTRAWF”-branded aftermarket cartridges from five manufacturers (Ecolife Technologies, Inc., Ningbo Pureza Technology, LLC, Qingdao Ecopure Filter Co., Ltd., WaterH Inc and YiHangGou Trading Co., Ltd., under model numbers such as MB-ULTRAWF-D, GF-ULTRAWF, AQF-ULTRAWF, WH-ULTRAWF and MOUNTAIN FLOW MF-ULTRAWF), none of them from Frigidaire or Electrolux, and a federal court has held sellers of “Frigidaire PureSource ULTRAWF”-compatible replacement cartridges liable for patent infringement over the filter's housing design. This record's certified claims apply only to the genuine Frigidaire/Electrolux part; it makes no certification-scope claim, positive or negative, for any third-party cartridge. The Frigidaire ULTRAWF's recorded operating limits are Water pressure at least 30 psi and up to 100 psi, Water temperature at least 33 °F and up to 100 °F, Service flow up to 0.65 gpm, Throughput before replacement up to 200 gallons, verified 2026-09-11.

Frigidaire's own Performance Data Sheet states “NSF Certified: Yes” and “Tested and certified by NSF International against NSF/ANSI Standards 42, 53 and 401,” but a same-day, same-name live search of NSF's own Drinking Water Treatment Units directory returns no Frigidaire or Electrolux listing for ULTRAWF. The certified reduction claims this record publishes trace only to IAPMO R&T, an equivalent third-party certifier to NSF, not to NSF's own directory.[1][2]

None of the five active IAPMO R&T certificates that list ULTRAWF, under that model number or its PureSource Ultra trade name (WP-14065, WP-16165, WP-30821, WP-14066 and WP-30822), carries a hardness, calcium, magnesium or scale-reduction claim, and Frigidaire's own Performance Data Sheet makes none either. This is not a water softener and will not reduce hardness or scale.[1][2][3]

It treats only the water one refrigerator dispenses as chilled water and ice. It is a cartridge that seats inside the appliance, not a point-of-entry or whole-house filter, so no other tap in the home is affected.[1][2]

It does not fit every Frigidaire refrigerator. Frigidaire's own materials scope ULTRAWF to refrigerators built for the PureSource Ultra or PureSource 3 filter housing manufactured after 2009. IAPMO R&T's certificates list EPTWFU01 (PureSource Ultra II), FPPWFU01 and FPPWFU02 (PurePour) and WFPTU26 as separate models, each rated 0.65 gpm and a smaller 125-gallon capacity than ULTRAWF's own 200 gallons, with their own reduction-claim sets on the same certificate — a refrigerator built for one of those newer systems does not take a ULTRAWF cartridge.[1][2]

Recalls and litigation
LitigationKX Tech LLC v. Zuma Water Filters, Inc. et al. (D. Conn., 3:16-cv-01433): KX Technologies sued several sellers of refrigerator-filter cartridges for patent infringement over filter-housing “Push Technology” and “Cassette Filter Technology” patents. Two defendants (Dista Filter and Waterfall Filter Company) defaulted; the amended complaint's infringement allegations name a replacement filter for “the Frigidaire PureSource ULTRAWF filter cartridge” among the infringing products. On April 19, 2018 the court granted default judgment, found the defendants liable for patent infringement, and permanently enjoined them; on July 5, 2018 the court separately found the case “exceptional” and awarded KX Technologies $40,080.71 in attorney's fees and costs.

The Frigidaire ULTRAWF against its family and its rivals
The Frigidaire ULTRAWF has 2 siblings in its family: WF3CB, EPTWFU01.
The rest of the family
| Model | What differs |
|---|---|
| WF3CB | Frigidaire's PureSource 3 cartridge for the same generation of refrigerator housing; IAPMO R&T lists WF3CB at 0.5 gpm / 200 gallons with a different reduction-claim set than ULTRAWF's own 0.65 gpm / 200-gallon listing. |
| EPTWFU01 | Frigidaire's PureSource Ultra II cartridge; IAPMO R&T lists it at 0.65 gpm / 125 gallons under the newer PurePour-era reduction-claim set (including PFOA/PFOS) — a separate model from ULTRAWF with its own claim set, not an interchangeable replacement for it. |
The Frigidaire ULTRAWF and cartridges sold as compatible
Live IAPMO R&T certificates list the genuine Frigidaire/Electrolux ULTRAWF cartridge (trade name PureSource Ultra) under NSF/ANSI 42, 53, 401 and 372. NSF's own live directory search for “ULTRAWF” returns 30 third-party aftermarket cartridges from five manufacturers (Ecolife Technologies, Inc., Ningbo Pureza Technology, LLC, Qingdao Ecopure Filter Co., Ltd., WaterH Inc and YiHangGou Trading Co., Ltd.; model numbers such as MB-ULTRAWF-D, GF-ULTRAWF, AQF-ULTRAWF, WH-ULTRAWF and MOUNTAIN FLOW MF-ULTRAWF) — none from Frigidaire or Electrolux. This record checked only the NSF directory for those third-party cartridges and makes no certification claim, positive or negative, for any of them; each would need its own dated lookup across NSF, IAPMO R&T and WQA before this record could say anything about its certification scope.[1][2]

Frigidaire ULTRAWF questions, answered
Is the Frigidaire ULTRAWF filter NSF certified?
Verified health claim
Not from NSF's own directory: a live search of NSF's Drinking Water Treatment Units directory for ULTRAWF on 2026-09-11 returns no Frigidaire or Electrolux listing, even though Frigidaire's own Performance Data Sheet says “NSF Certified: Yes.” The cartridge's certified reduction claims for NSF/ANSI 42, 53 and 401 instead trace to active IAPMO R&T listings, an NSF-equivalent third-party certifier.
What does the Frigidaire ULTRAWF water filter actually remove?
Verified health claim
Per its active IAPMO R&T listings, ULTRAWF is certified to reduce chlorine taste and odor and Class I particulate (NSF/ANSI 42); lead, mercury, asbestos, cysts, VOCs including MTBE, and trihalomethanes among other organics (NSF/ANSI 53); and atenolol, ibuprofen, trimethoprim and microplastics (NSF/ANSI 401). Frigidaire's own marketing additionally mentions pesticides, insecticides, BPA and “pharmaceuticals” broadly, but not every one of those brand-stated items — BPA (Bisphenol A) specifically — appears on ULTRAWF's own IAPMO listings.
How often do I need to replace the ULTRAWF filter?
Every 6 months or 200 gallons, whichever comes first, per Frigidaire's own Performance Data Sheet — though the same sheet's Recommended Change Frequency field separately gives a range of 3 to 6 months, and several Amazon reviewers for this exact listing report needing to replace it sooner than 6 months.
Does the ULTRAWF filter fit all Frigidaire refrigerators?
No. Frigidaire's own materials scope it to refrigerators built for the PureSource Ultra or PureSource 3 filter housing manufactured after 2009. Refrigerators built for the newer PurePour system (FPPWFU01/FPPWFU02) or the PureSource Ultra II system (EPTWFU01) take a different, separately IAPMO-listed cartridge. Frigidaire's own datasheet directs buyers to the fits-models listing on Frigidaire.com to confirm fit.
How can I tell if a ULTRAWF filter is genuine and not a knockoff?
Check that the packaging carries Frigidaire's “Genuine Filters” seal — though Frigidaire's own datasheet notes that as packaging transitions, genuine filters may still ship in blue as well as the newer berry-colored design, so packaging color alone does not confirm authenticity. Frigidaire's own materials warn that “counterfeits and knockoffs put fridges and health at risk.” NSF's own directory separately lists 30 third-party “ULTRAWF-compatible” cartridges from five manufacturers (Ecolife Technologies, Inc., Ningbo Pureza Technology, LLC, Qingdao Ecopure Filter Co., Ltd., WaterH Inc and YiHangGou Trading Co., Ltd.), none from Frigidaire or Electrolux, and a federal court has held sellers of ULTRAWF-compatible cartridges liable for patent infringement over the filter's housing design.

What we could not establish, and why
| Field | Why it is blank |
|---|---|
| certified.certIndexKey | The local certification index's electrolux-home-products.json (4 records) and frigidaire.json contain no ULTRAWF or PureSource Ultra entry; no sibling-model key was substituted. |
| fit.bathroomsServed | Bathroom sizing does not apply to a refrigerator cartridge, and none of the reviewed Frigidaire materials publish a bathroom range for it. |
| fit.householdSize | Frigidaire's Performance Data Sheet gives a usage-based change-frequency range (3-6 months) rather than a household-size rating; no household count was inferred from it. |
| fit.roOutputGpd | ULTRAWF is not a reverse-osmosis membrane; no RO output applies. |
| fit.roTankCapacity | ULTRAWF is a refrigerator cartridge with no RO storage tank; no capacity applies. |
| fit.dimensions | Frigidaire's Performance Data Sheet gives Retail Packaging dimensions (11 1/5" x 2 2/5" x 2 3/10") rather than confirmed cartridge dimensions, and Amazon's separately labeled “Product Dimensions” (11" D x 2.25" W x 3" H) do not exactly match those packaging figures, so no single confident cartridge-dimension value was selected. |
| fit.connectionSize | Frigidaire's Performance Data Sheet and Amazon listing describe a push-to-lock cartridge but publish no connection diameter. |
| fit.requiresElectricity | The reviewed installation materials do not state an independent electricity requirement for the cartridge itself; absence of a wiring step was not converted into a sourced boolean. |
| fit.requiresDrain | The reviewed installation materials do not state an independent drain requirement for the cartridge itself; absence of a drain step was not converted into a sourced boolean. |
| cost.msrp | Frigidaire's own ULTRAWF product page (frigidaire.com) could not be reached from this research environment — both a rendered browser navigation and a raw HTTP fetch failed with a connection-level error despite the page being live and indexed by search engines — so no brand-displayed list price was confirmed; only the Amazon street price was recorded. |
| cost.wasteRatio | ULTRAWF is not an RO membrane and no waste-to-product water ratio applies or is published. |
| cost.warranty | Amazon's spec table names a “LIMITED” Manufacturer Warranty Description with no stated term in years and no lifetime designation; the reviewed materials do not give enough to construct a cited warranty term. |
| cost.moneyBackGuarantee | No product-specific money-back guarantee distinct from ordinary retailer return policies was found in the reviewed OEM or retailer materials. |
| install.estimatedHours | Frigidaire's materials give a 3-minute post-install priming step but no stated total installation time; the priming duration was not repurposed as an install-time estimate. |
| seo.verification | The independent verify loop has not run; it owns this stamp. |
