VOSS still
Lower PFAS concern; pure glass container poses minimal risk.
VOSS Still is bottled water in borosilicate glass, a material with inherently low PFAS risk. The brand does not disclose PFAS testing or claim PFAS-free status, and no public lab data or recalls exist.

What VOSS still is made of, ingredients and materials
VOSS Still uses a borosilicate glass bottle, a chemically inert material that does not leach contaminants into water under normal use. Borosilicate glass is manufactured by fusing silica with boron oxide, creating a durable matrix resistant to thermal shock and chemical attack. Unlike ceramic coatings, metal-lined containers, or plastic pitchers, glass poses no risk of lead, cadmium, BPA, or phthalate migration. The "Still" designation indicates no carbonation treatment, eliminating pressure-related stress on the container.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Thermal shock risk
Borosilicate glass is highly resistant to thermal shock, but rapid temperature changes (e.g., pouring boiling water into a cold bottle) can still cause cracking or breakage. This is a physical safety risk, not a chemical one.
Closure and gasket integrity
If the VOSS bottle includes a plastic cap or rubber gasket, those components may degrade or leach over time. Information on gasket material composition is not publicly detailed; inspect seals for discoloration or odor.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Surface degradation and micro-fractures
No reports of borosilicate glass bottles leaching silica or other compounds from micro-fractures under standard use. Glass is chemically stable even if the surface becomes scratched or etched.
Bacterial growth in storage
Glass itself does not harbor bacteria. Hygiene depends entirely on cleaning and storage practices; no inherent microbiological risk from the borosilicate container itself.
The full breakdown
The brand's record and disclosure
VOSS is a Norwegian bottled water brand owned by Moët Hennessy and distributed globally. Public disclosure on manufacturing standards and testing certifications is limited; the brand does not prominently publish third-party safety audits or material sourcing statements on its standard product line. No major product recalls or contamination incidents are on record for VOSS glass bottles. The brand's silence on PFAS and manufacturing transparency is typical for premium bottled water labels but does not indicate a safety failure with this specific glass product.
How it compares in its category
Glass water pitchers and bottles show lower concern in the beverage container category, with no hazard of leaching associated with plastic filters, ceramic glazes, or treated-aluminum pitchers on record. VOSS glass bottles typically cost more than plastic alternatives, reflecting material durability and inertness. Most competitor glass bottles (Lifefactory, soda-stream glass carafes) offer similar safety profiles; VOSS competes on design and brand positioning rather than unique safety advantages.
If you buy it
Store away from direct sunlight and thermal extremes to maintain clarity and structural integrity over time. Borosilicate glass is suitable for hot water and ice; avoid pouring boiling water directly onto cold glass, which can cause thermal shock and cracking. Hand wash if possible to preserve any interior clarity coating; dishwasher use is unlikely to cause hazard but may dull the glass surface over years. Replace only if glass cracks or chips appear, as borosilicate does not degrade chemically with age or repeated use.
