Contigo · Insulated Travel Drinkware
Contigo Snapseal Tumbler
Lower PFAS concern. Stainless steel and plastic tumbler with no known problematic coatings.
Contigo Snapseal uses stainless steel and polypropylene, materials not typically treated with PFAS. No brand disclosure on PFAS, but standard construction presents lower risk than coated drinkware.

The full breakdown
What it's made of and why it matters
The Contigo Snapseal uses a stainless steel outer body, which is chemically inert and does not leach metals or compounds into beverages under normal use. The lid and seal are polypropylene (PP), a plastic rated for temperatures up to roughly 100-120C. Polypropylene is considered one of the safer food-contact plastics because it does not contain BPA or most phthalates, though it can degrade if exposed to prolonged heat or certain solvents.
The brand's record and disclosure
Contigo has not made prominent public statements about PFAS or detailed material sourcing, but the company markets these tumblers as suitable for beverages and does not rely on non-stick coatings that typically contain PFOA. No major product recalls or safety controversies are publicly documented for the Snapseal line. The brand is owned by Newell Brands, a large consumer goods manufacturer with standard compliance practices but limited transparency on emerging chemicals.
How it compares in its category
Stainless steel tumblers are among the safest reusable drinkware options because they avoid both ceramic-glaze hazards and plastic-only construction. The polypropylene lid is typical for this price point; glass-lid alternatives exist but are less durable. Most competing stainless steel tumblers (Hydro Flask, S'well, Zojirushi) use similar material combinations, making Contigo competitively safe.
If you buy it
Do not place the polypropylene lid or seals in the dishwasher or expose them to boiling water repeatedly, as heat can warp or degrade the plastic. Hand wash the lid and seal in warm water. Replace the lid gasket if it cracks, discolors, or stops sealing properly, as compromised seals can harbor bacteria. The stainless steel body is durable and does not require special care beyond normal washing.
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.”
Polypropylene thermal degradation
Repeated exposure to hot liquids near or above 100C can cause polypropylene lids and seals to soften, warp, or leach minor degradation products. Normal hot beverage use (below 80C) poses minimal risk.
Bacterial growth in lid seals
Narrow crevices in the Snapseal mechanism can trap moisture and food residue if not thoroughly cleaned, creating conditions for mold or bacterial growth. Regular hand washing and occasional disassembly (if possible) reduce this risk.
BPA or phthalate leaching from polypropylene
Polypropylene (PP) is not formulated with BPA or most phthalates by default. No documented cases of BPA/phthalate leaching from Contigo Snapseal lids are on record.
Aluminum leaching from stainless steel body
True stainless steel does not leach aluminum. Contigo Snapseal uses stainless steel, not aluminum, so this hazard class does not apply.
Off-gassing or odor transfer
New polypropylene lids may emit a faint plastic odor for the first few uses. This typically dissipates after hand washing and air drying. It is not a health hazard but can affect beverage taste if the tumbler is used immediately out of packaging.
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.
