How to read a "PFAS-free" product claim
"PFAS-free" on a product listing can mean several different things depending on who tested what, at what detection limit, and against which analyte list. Here's how to read the claim in front of you instead of assuming it answers your specific question.
PFAS (per- and polyfluoroalkyl substances) is a large family of thousands of compounds, not one chemical. A "PFAS-free" claim is only as strong as the testing behind it—which analytes were measured, at what reporting limit, on which lot, and whether the whole product was tested or just a raw material.
Where Cyverna's claim comes from today
Across the current catalog, PFAS-related wording falls into two states, both drawn directly from the supplied product descriptions:
| Status | What it means |
|---|---|
| Source-designated PFAS Free | The supplied product description states "PFAS Free." This is the manufacturer's/supplier's own wording as provided—Cyverna has not independently verified the underlying test method, analyte list, or detection limits behind it. Treat it as a starting point for your own evidence review, not a completed one. |
| No PFAS-free designation | No PFAS-related claim was supplied for this product. This is not a statement that the product contains PFAS—it simply means no claim was made either way. |
Neither state is independent lab confirmation. If your work requires a validated PFAS-free determination, request the underlying documentation before you rely on the label.
Questions worth asking before you rely on a claim
- What was tested? The finished product, a raw material, or a single component?
- Which analytes? A handful of legacy PFAS compounds, or a broader panel? "PFAS" covers thousands of compounds—no single test covers all of them.
- What method and detection limit? A claim is only as sensitive as the method used to support it.
- What lot, and how current? Formulations and suppliers change; a claim tied to one lot doesn't automatically carry forward.
- Does it cover your whole workflow? A PFAS-free filter doesn't make the rest of your sampling and handling chain PFAS-free.
What to do if you need a documented answer
Request the certificate or supporting documentation for the exact SKU and lot you're ordering. If nothing is on file, say so in the request—Cyverna will tell you plainly if evidence isn't available rather than restate the source description as if it were a confirmed result.
