Amazfit · Waterproof Fitness Trackers & Cases
Amazfit Active 3 Premium GPS Running Smartwatch
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes aluminum case, glass screen, silicone band, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

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.
Aluminum leaching from case
Sweat (lactic acid, chlorides) can promote minimal aluminum dissolution from the case over months of heavy use, though the amount absorbed through skin contact is negligible and below regulatory concern thresholds for healthy individuals. Pre-existing kidney disease or aluminum sensitivity may warrant caution.
Silicone band contact dermatitis
Individual sensitivity to silicone additives or residual processing chemicals is rare but documented in fitness tracker users; symptoms include localized rash under the band. Incidence is not product-specific and occurs across all silicone wearables; mitigation is periodic band removal and skin airing.
Seal degradation and bacterial growth
IP68 rating relies on gaskets and adhesive seals; over 2-3 years or with repeated thermal stress (hot showers), seals can fail silently, allowing moisture ingress into the case cavity where bacteria and mold can proliferate without visible symptoms until corrosion is advanced.
Glass screen breakage and sharp edges
While Gorilla Glass is chip-resistant, hard impacts can cause edge fractures; the sharp edges pose a minor laceration risk to the wearer's wrist or to fingers during removal or cleaning. This is a mechanical hazard rather than chemical.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Electrolyte leakage from internal battery
No recalls or documented field reports of lithium battery leakage in the Active 3 Premium exist. However, if the seal fails (see Seal degradation hazard), internal electronics can corrode and potentially leak electrolyte; this is not an inherent material issue but a consequence of water ingress.
The full breakdown
What it's made of and why it matters
The Amazfit Active 3 Premium uses an aluminum alloy case, which is lightweight and corrosion-resistant but can leach trace amounts of aluminum under acidic conditions (sweat, citric acid-based cleaners). The glass screen is chemically inert and poses no leaching risk. The silicone band is the primary contact surface with skin; commercial-grade silicone is generally stable and does not off-gas volatile compounds under normal wear conditions, though some formulations may contain trace additives that occasionally trigger contact dermatitis in sensitive individuals.
The brand's record and disclosure
Amazfit (subsidiary of Huami, owned by Xiaomi) has not published material safety data sheets or comprehensive chemical disclosure statements for this product. No PFAS-containing water repellent coatings have been stated or publicly documented for this model. The brand maintains IP68 water resistance through mechanical seals and material selection rather than fluorinated treatments. No significant safety recalls or regulatory actions against Amazfit wearables have been publicly recorded in major consumer safety databases.
How it compares in its category
Aluminum-bodied fitness trackers are the standard in this category and generally carry lower chemical risk than polymer housings. This product's material profile is typical and unremarkable compared to competitors like Garmin, Polar, or Apple Watch. The main differentiation is durability of the silicone band and the aluminum finish over time rather than acute chemical hazards. Most fitness tracker risks come from poor seal maintenance (allowing bacterial colonization in crevices) rather than material composition.
If you buy it
Rinse the band and case under clean water after sweaty workouts or salt-water immersion to prevent silicone degradation and aluminum oxidation. Do not use abrasive cleaners or harsh solvents; mild soap and water suffice. Replace the silicone band if it shows visible cracking, discoloration, or becomes sticky, as these indicate polymer breakdown. Check the seals around the charging contacts and screen edge monthly; if water visibly enters the case, discontinue use and contact support, as the internal components are not potted and may corrode.
