Ashland Chill 2.0 Insulated Stainless Steel Water Bottle
Lower PFAS concern. Stainless steel core is inherently safe.
Contigo's stainless steel water bottle has no reported PFAS in the primary container. Plastic components and cap design are typical for the category but undisclosed.

The full breakdown
What it's made of and why it matters
The Ashland Chill 2.0 uses food-grade stainless steel as the inner container, which is chemically inert and does not leach metals or BPA into liquids at any temperature. The insulation layer and plastic cap are the only polymer components exposed to contents or handling. Stainless steel construction eliminates the primary leaching pathways found in aluminum, ceramic-coated, or plastic-lined bottles.
The brand's record and disclosure
Contigo maintains a general commitment to consumer safety but has published no detailed PFAS or hazardous substance transparency reports. The company does not voluntarily disclose material composition beyond marketing specs. No major recalls or documented safety incidents specific to this model are on public record. The silent stance on PFAS reflects industry-wide caution rather than confirmed concern for this product line.
How it compares in its category
Stainless steel water bottles are generally considered the safest option in the insulated bottle category, avoiding risks present in aluminum cores or plastic-lined variants. Contigo's design is typical of mainstream double-wall insulated bottles; it does not use experimental coatings or proprietary polymer layers. Comparable models from brands like Hydro Flask and S'well offer similar material safety profiles at higher price points.
If you buy it
Hand wash the cap and lid gasket regularly to prevent bacterial biofilm in hard-to-reach seams. Do not use in dishwashers if you wish to maximize seal longevity. Replace the plastic cap/lid assembly if cracks develop, as this can expose insulation materials. Stainless steel itself requires no special maintenance and will not degrade from hot or cold beverages.
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.”
Bacterial growth in plastic cap seals
Silicone gaskets and plastic cap threads can harbor mold or bacteria if not dried thoroughly after washing. This is a hygiene issue, not a chemical toxicity issue, but relevant to long-term safe use.
Plastic cap polymer breakdown over time
No published data on leaching from Contigo's polypropylene or thermoplastic cap materials at typical beverage temperatures. Standard plastics used in caps are not known to degrade under normal conditions, though mechanical stress (drops, cracks) could theoretically expose new surfaces.
Insulation layer integrity
Double-wall construction typically uses polyurethane or polystyrene foam insulation sealed between steel walls. No hazard is documented if the seal remains intact; damage exposing insulation to beverages is rare in normal use but would not create acute toxicity risks.
Lead or heavy metals in stainless steel
Food-grade stainless steel (typically 18/8 or 18/10 alloy) is not a source of lead or cadmium leaching. Contigo's stainless interior does not carry the risks associated with ceramic glazes or painted coatings.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 75% 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.
