A “PFAS-free” claim can be a useful starting point, but buyers need to know exactly what it means. For a municipality, public institution or industrial company, it is most useful when supported by clear documentation, a defined scope and a verifiable supplier response.
Start with the function you need
Rather than simply requesting a different material, describe what the product must do. Must it withstand fatty food, frequent washing, a specific temperature or process fluids? Alternatives can then be compared by both function and composition. A substitute must suit the intended use, not merely have a different name.
What to ask suppliers
Ask three basic questions: are PFAS intentionally added, which part of the product does the declaration cover, and what evidence supports it? For a complex product, include coatings, seals and other functional parts. Any analysis supplied should identify the compounds measured, the method and the quantification limit.
A declaration of no intentionally added PFAS is not the same as a laboratory result below a given limit. One describes composition or a manufacturing decision; the other describes a specific test. Procurement documents should distinguish them rather than assume one replaces the other.
Base water decisions on measurements
EPA recommends asking the water supplier for information as a practical step for users of public water systems. Where a problem is confirmed, select treatment with demonstrated performance for the PFAS concerned and follow the operating instructions. The general label “water filter” does not tell you which compounds the filter reduces. EPA: reducing exposure.
A phased plan for your organisation
For larger organisations, we suggest reviewing product groups, assigning responsibilities and checking new specifications at the next purchase. Prioritise uses for which reliable data and a viable alternative are available. It is also useful to agree that suppliers will notify you of formulation changes.
Preventing inputs and treating water already affected address different parts of the same task. When introducing a new raw material, a company should assess its impact in the process documentation; if PFAS are suspected in water, it should prepare a sampling plan. Decisions then rely on product and process data, rather than an advertising label alone.
