Materials and contact
A concise, evidence-scoped look at where plastic and silicone sit in this product’s food, drink, mouth, steam, and condensate paths.
- Plastic contact
- Plastic is present; its contact path is not fully verified
- Silicone contact
- Silicone contact is not fully verified
Materials and contact path: Purifyou identifies glass bottles, external silicone sleeves and caps with stainless steel interiors. Brand guidance identifies polypropylene in the cap. The exact seal, insert perimeter and thread carrier are not fully mapped across the listed variants, so plastic and silicone contact remain unconfirmed.
“Not fully verified” means a relevant component, treatment, or variant still needs exact-product evidence. It is not a positive plastic-free or silicone-free claim.
