Google Air Active Band, Large - Berry
Lower concern. Elastomer band material is not linked to PFAS.
The Google Air Active Band uses an elastomer band likely silicone or TPE, a material not associated with PFAS. Google has no PFAS statement on record for this product.

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.
Bacterial or fungal growth on band material
Elastomer surfaces can harbor bacteria and fungi if not cleaned regularly, especially in warm, moist conditions. This is a hygiene issue rather than a material toxicity issue but is relevant for skin health.
Elastomer degradation and microparticle shedding
Over years of use, elastomer can crack and shed micro-particles, particularly if exposed to heat or UV light. The health impact of inhaled or ingested microparticles from elastomer is not well studied, but this is a known wear-out mechanism.
Undisclosed additives in elastomer formulation
Elastomer manufacturing typically includes plasticizers, stabilizers, or processing aids that are not disclosed by Google. Common additives like phthalates or heavy metal stabilizers are used in some TPE formulations, though not typical in premium fitness band materials.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Synthetic dye or pigment toxicity in elastomer
No recalls or reported cases of allergic reaction or dermal toxicity from Google Air Active Band colorants. Elastomer-based dyes used in fitness bands are generally non-migratory under body temperature and moisture conditions.
Contact dermatitis or skin sensitization
Silicone and TPE are considered hypoallergenic materials with rare documented cases of contact dermatitis in fitness band wearers. Individual sensitivity to synthetic elastomers or residual manufacturing chemicals is possible but not established for this specific product.
The full breakdown
What it's made of and why it matters
The Google Air Active Band is an elastomer strap, most likely silicone or thermoplastic elastomer (TPE), chosen for flexibility, sweat resistance, and skin contact tolerance. Silicone and TPE are generally inert at body temperature and do not off-gas or leach under normal wear conditions. The berry color is achieved through synthetic dyes or pigments mixed into the elastomer during manufacturing; the specific colorant chemistry is not disclosed by Google.
The brand's record and disclosure
Google does not publicly disclose detailed material safety data sheets, chemical composition, or third-party test results for the Air Active Band. The company has no known major product safety recalls or documented controversies involving wearable band toxicity. Google's silence on PFAS and other chemical additives is consistent with industry practice for consumer wearables but leaves independent verification impossible.
How it compares in its category
Elastomer fitness bands across brands (Apple, Fitbit, Samsung) follow similar material and manufacturing standards. Silicone and TPE straps are among the lowest-risk wearable options compared to fabric, leather, or coated alternatives. Most competitors offer equally opaque chemical disclosure, making transparency a sector-wide weakness rather than a Google-specific problem.
If you buy it
Rinse the band regularly with mild soap and water, especially after exercise or prolonged skin contact, to remove sweat and bacteria. Avoid prolonged exposure to direct heat sources (hot water over 130F, direct sunlight for extended periods) as elastomers can degrade. Replace the band if visible cracking, stickiness, or discoloration develops, as these may indicate material breakdown. Store in a cool, dry place when not in use.
