PFAS score
Triexta · Carpets & Rugs
True Harmony 778 Dakota 35 oz. Triexta Smartstrand Texture Indoor Carpet Flooring 12' Feet Wide (9 sf / yd)
Skip unless you verify stain treatment chemistry, Triexta fibers often receive PFAS-based finishes for durability.
Triexta (polyester) is inherently synthetic but lower-concern than acrylic. However, the product's stain and soil resistance treatment is not disclosed. Carpet treatments frequently rely on fluorochemicals (PFAS) for water and grease repellency. No brand commitment to PFAS-free manufacturing or third-party verification is evident.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
