Ello · Insulated Drink Tumblers
Ello Port 30oz Tumbler with Carry Loop & Integrated Handle
Lower concern, as stainless steel core is unlikely PFAS source.
Ello tumbler is primarily stainless steel, a lower-risk material. Lid and handle polymers are unspecified, but tumblers rarely undergo water-resistant treatments requiring PFAS.

What Ello Port 30oz Tumbler with Carry Loop is made of, ingredients and materials
The Ello Port is built around a stainless steel double-wall core, which is chemically inert and does not leach metals or require coating maintenance. The lid and carry loop are elastomer or plastic (likely silicone or polypropylene based on typical Ello designs), which contact only cold or warm beverages, not hot liquids at risk of degradation. The seal gasket is the primary plastic-contact point and warrants inspection for visible wear, but stainless steel avoids the coating-failure and metal-leaching risks of ceramic or aluminum-core tumblers.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Plastic/elastomer lid and gasket composition
Ello does not publicly disclose whether the lid elastomer or gasket contains BPA, BPS, or phthalates. Silicone and polypropylene are typically low-risk, but sourcing and additives are not detailed in available product information.
Gasket and seal degradation over time
Elastomer or plastic gaskets may degrade, crack, or leach compounds if stressed by heat, freezing, or repeated dishwasher cycles. Visual inspection every few months is a practical early-warning step.
Carry loop and attachment durability
The integrated carry loop is often silicone or elastomer and may crack or degrade under repeated tension or UV exposure. Replacement is straightforward but not always sold as a standalone part.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Metal leaching from stainless steel
Food-grade stainless steel (typically 18/8 or 18/10 alloy) does not leach nickel, chromium, or other metals under normal beverage storage conditions. No public reports of leaching from Ello or comparable stainless steel tumblers exist.
Coating or finish failure
Stainless steel has no applied ceramic, enamel, or paint coating, so no coating-peeling, lead-glaze, or Teflon-type coating off-gassing risks apply to the vessel itself.
The full breakdown
The brand's record and disclosure
Ello does not publish detailed material safety data sheets or third-party certifications for individual products on its website. The brand has no widely documented safety recalls or chemical controversies in public databases as of recent records. However, lack of transparency on plastic component composition and sourcing limits independent verification of elastomer or BPA/BPS status in lid and gasket materials.
How it compares in its category
Stainless steel tumblers have lower concern regarding coating degradation and metal leaching compared to other reusable drinkware materials. Most competitors (ceramic-lined, powder-coated metal, or plastic-walled alternatives) carry higher risk profiles for lead in glaze, Teflon-type coating off-gassing, or BPA migration. The Ello Port's main trade-off versus higher-end alternatives is less rigorous public disclosure of plastic component sourcing.
If you buy it
Hand wash the lid and gasket to extend seal integrity and avoid plastic stress from high heat or dishwasher cycles. Inspect the gasket and lid seams quarterly for cracks, discoloration, or odor, which signal degradation and warrant replacement. Do not fill with beverages above 140F (60C) to minimize any thermal stress on plastic components. The stainless steel body itself is durable indefinitely; plan to replace the lid assembly every 1-3 years depending on use frequency.
