Crock-Pot Slow Cooker Liners
Slow cooker liners are likely lower PFAS concern as uncoated fabrics, but brand transparency is absent.
Crock-Pot liners are single-use disposable inserts made from heat-resistant fabric (typically polyester or nylon blend) with no added nonstick coating, making them lower concern for PFAS than coated cookware. However, Liners Direct provides no public disclosure about material composition or PFAS testing.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
