Pros & Cons
Pros
- Official Frigidaire page names NSF/ANSI 42, 53, and 401 certification in PureSource Ultra systems
- 200-gallon/six-month service cycle gives a clear maintenance deadline
- Genuine-filter packaging and compatibility warnings are useful for avoiding counterfeit or wrong-family cartridges
Cons
- ULTRAWF is not interchangeable with every Frigidaire filter family
- Third-party compatible cartridges need separate receipts before carrying health-effect claims
- Annual cartridge cost is high for a fridge-only drinking-water path
At a Glance
Overview
Frigidaire ULTRAWF PureSource Ultra is a refrigerator cartridge where the official receipt is clearer than most marketplace summaries. Frigidaire names the standards, capacity, change frequency, and flow rate on its product page.
That clarity is useful, but only if the buyer owns a refrigerator that actually takes ULTRAWF. Filter Report treats compatibility as part of the claim, not a footnote.

Certification Receipt
Frigidaire's ULTRAWF page states that the filter is tested and certified by NSF International against NSF/ANSI Standards 42, 53, and 401 in PureSource Ultra for the reductions listed on the performance data sheet. It also names WQA sustainability certification separately.
Compatibility Boundary
ULTRAWF is a PureSource Ultra cartridge, not a universal Frigidaire replacement. Match the current filter model and refrigerator documentation before buying, especially because Frigidaire has adjacent filter families with similar names.
Maintenance Economics
The official service frame is 200 gallons or three to six months. At current listing prices, a normal two-filter year is a meaningful recurring cost, so the genuine receipt has to be worth more to the buyer than the cheapest compatible alternative.
Filter Report Verdict
Frigidaire ULTRAWF is a useful receipt-led cartridge pick because the official page gives standards, capacity, flow, and replacement cadence in one place. It should be recommended only to owners whose refrigerator specifically calls for ULTRAWF/PureSource Ultra.
