What Waterdrop Official ATP Tour Purpose Thermo is made of, ingredients and materials
This bottle uses borosilicate glass as the primary contact surface, which is chemically inert and does not leach compounds into water at any temperature. Borosilicate glass is specifically designed to resist thermal shock and is food-safe by default. The stainless steel components (likely 18/8 or similar food-grade alloy) do not corrode in contact with water, and silicone gaskets are inert rubber polymers that do not degrade into the liquid under normal use. This material combination has lower concern for leaching compared to common alternatives.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Silicone gasket degradation and bacterial growth
Silicone gaskets in reusable bottles can accumulate bacteria or mold if not cleaned thoroughly or dried between uses. This is a maintenance issue, not a material defect, and is manageable with proper hygiene.
Glass breakage and sharp injury
Borosilicate glass is durable but can shatter if dropped or subjected to extreme impact, creating sharp fragments. This is an inherent physical property of the material, not a chemical hazard.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Stainless steel corrosion or leaching
Food-grade stainless steel (18/8 type) does not corrode or leach nickel or chromium into water under normal storage conditions. No public reports of corrosion issues with Waterdrop bottles have been documented.
Borosilicate glass leaching
Borosilicate glass is chemically inert and does not leach lead, cadmium, or other contaminants into water at any temperature range typical for beverage storage.
Off-gassing or volatiles from manufacturing
Glass, steel, and silicone do not off-gas volatile organic compounds (VOCs) after production. No odor or VOC concerns are documented for this product category.
How is this PFAS grade calculated?
The brand's record and disclosure
Waterdrop is a direct-to-consumer water filtration brand with minimal public disclosure of material testing or safety certifications. The brand does not appear to have published third-party test reports or certifications such as NSF or FDA approval for this specific bottle. No major safety recalls or controversies have been documented for Waterdrop water bottles in public health databases. The brand's silence on PFAS in promotional materials is notable given industry scrutiny, though the borosilicate glass design inherently eliminates PFAS migration risk.
How it compares in its category
Glass water bottles show lower concern for leaching compared to polycarbonate, polypropylene, or aluminum bottles. The Waterdrop ATP Tour bottle is directly comparable to other glass bottles from brands like Pyrex, Emeco, or Hydro Flask glass variants. Stainless steel lid and gasket construction is standard in this segment. This product avoids common plastic water bottle issues entirely, making it a lower-risk choice than most reusable bottles on the market.
If you buy it
Hand wash the silicone gasket regularly to prevent bacterial biofilm or mold growth in the seal, especially if stored wet. Do not expose the bottle to sudden temperature changes (ice water to boiling water immediately) to avoid glass stress fractures, though borosilicate glass is highly resistant to thermal shock. Replace the silicone gasket if it shows visible cracks, discoloration, or persistent odor. Store empty and dry when not in use for extended periods to minimize any moisture-related deterioration of the seal.
