Contigo DualSip Leakproof Insulated Water Bottle 2-Way Lid
Lower concern. Stainless steel core avoids known PFAS sources.
Contigo makes no PFAS claims. Primary construction is stainless steel, which carries minimal PFAS risk. Lid seals and gaskets are potential concern but not routinely tested.

Category baseline
other is a category where PFAS exposure is more common.
No PFAS disclosure

The full breakdown
What it's made of and why it matters
The Contigo DualSip bottle body is stainless steel, which does not leach metals or require protective coatings that degrade over time. The lids and seals are elastomer and plastic (likely polypropylene or polyethylene); these materials are generally stable at normal use temperatures but should not be exposed to boiling water or prolonged heat. The dual-lid design means two separate sealing systems, increasing the number of potential contact points with liquid, though stainless steel itself is chemically inert.
The brand's record and disclosure
Contigo does not publicly disclose detailed material testing or PFAS sourcing statements. The brand has no major recalls tied to chemical contamination in water bottles on public record. Contigo does not advertise third-party certifications (such as NSF or FDA material compliance statements) for this specific model, making independent verification of material claims difficult. The company maintains basic food-contact compliance but has not published transparency reports on manufacturing hazards.
How it compares in its category
Insulated water bottles with stainless steel bodies are among the safest options available; they avoid the BPA and leaching risks of plastic-bodied alternatives. The DualSip's plastic lids are standard for this category and pose no greater risk than competing brands (Hydro Flask, S'well, YETI all use similar elastomer seals). The two-way design is a convenience feature that does not introduce new chemical risks compared to single-valve bottles.
If you buy it
Do not fill with liquids hotter than 160F (70C) to avoid potential softening or off-gassing of the plastic lids. Hand-wash the lids and seals regularly, as stagnant moisture inside the seals can promote mold or bacterial growth if the bottle sits unused for days. Replace the rubber gasket if it becomes visibly cracked or loses its seal. Avoid prolonged exposure to direct sunlight, which can degrade the elastomer over years of use.
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.”
Plastic lid and elastomer seal degradation
Repeated thermal stress or prolonged exposure to hot liquids can soften or degrade the plastic components. No specific failures reported for this model, but typical plastic lids may release trace compounds if damaged; inspect regularly.
Bacterial or mold growth in seals
The dual-seal design creates narrow passages where moisture can accumulate if not thoroughly dried. Risk is minimal with proper hand-washing between uses but present if bottle is stored wet or sealed while damp.
BPA or other bisphenols in plastic components
Contigo has not published material data sheets confirming BPA-free status of this bottle's lids. Modern water bottle manufacturers typically avoid BPA, but explicit third-party confirmation is absent from publicly available sources for this specific product.
Heavy metals in stainless steel or coatings
Stainless steel itself does not leach lead or cadmium under normal use. No recalls or test results documenting metal migration have been reported for Contigo bottles.
Off-gassing from plastic lids at elevated temperature
Polypropylene and polyethylene lids may release volatile organic compounds if exposed to temperatures above 160F (70C). Contigo does not specify the melting or softening point of its lid materials in consumer-facing documentation.
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.
