Diversitech Ultra Grill Mat
Skip until coating is transparent, grill mats often use Teflon-type coating or similar Teflon-family coating without disclosure.
The Diversitech Ultra Grill Mat is a fiberglass-based cookware accessory, but the brand provides no public disclosure of the nonstick coating's composition. Grill mats commonly use Teflon-type coating or other Teflon-family coating known to contain or off-gas PFAS.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
