Monofilament Sufix Advance
Lower concern, nylon monofilament has no established PFAS coating, but manufacturer discloses nothing.
Sufix Advance monofilament is primary nylon fishing line with no visible Teflon-family coating or water-repellent coating. Sufix makes no public PFAS claims or disclosures. Nylon line itself carries lower intrinsic PFAS risk compared to coated or treated products, though independent lab testing is absent.

The full breakdown
What it's made of and why it matters
Sufix Advance is extruded nylon monofilament, a single-strand polymer without coatings, dyes, or additives typical of finished consumer goods. Nylon (polyamide-6) is chemically stable and does not leach under normal freshwater or saltwater use. The material is designed for mechanical strength and abrasion resistance, not food contact or skin exposure, which eliminates several hazard pathways present in other product categories.
The brand's record and disclosure
Sufix (owned by Rapala-VMC) does not publicly disclose detailed material safety data, certifications, or testing results for monofilament lines. No documented product recalls or chemical safety controversies are on record for this product line. The company maintains standard fishing-industry practices but offers minimal transparency beyond performance claims.
How it compares in its category
Monofilament fishing lines are the baseline product category; alternatives include braided lines (polyethylene, sometimes with coatings) and fluorocarbon lines (polyvinylidene fluoride). Monofilament nylon carries no greater chemical hazard profile than these alternatives and avoids the coating-related leaching risks present in some premium or specialty lines. It is the simplest and most chemically stable option.
If you buy it
Store in a cool, dry place away from direct sunlight to prevent UV embrittlement over time; this is a mechanical, not chemical, concern. Nylon monofilament does not require special handling or maintenance beyond typical fishing-line care. Replace when line shows visible wear, cloudiness, or loss of strength, typically annually with regular use. Disposal through standard waste is acceptable; nylon is not toxic but is non-biodegradable.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
UV degradation and microplastic release
Nylon monofilament degrades under prolonged UV exposure, becoming brittle and fragmenting into microparticles when broken or abraded. This is a mechanical and environmental concern rather than a chemical toxicity issue, but fragments may enter waterways during use or disposal.
Trace manufacturing residues or additives
No testing data or manufacturer disclosure identifies heavy metals, plasticizers, or processing chemical residues in Sufix Advance monofilament. Nylon extrusion typically involves minimal additive packages, and no recalls or safety alerts document contamination.
Leaching into water
Nylon monofilament is inert in aqueous environments and does not leach monomers, plasticizers, or dyes into freshwater or saltwater. This distinguishes it from certain coated or dyed alternatives.
Skin or eye irritation from material contact
Direct contact with nylon monofilament does not pose chemical irritation or sensitization risk. The only concern is mechanical abrasion if line cuts skin, which is a handling hazard, not a chemical one.
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.
