{lot Of 63 Watches} Epson Ps-100 Pulsense Heart Rate Activity Monitor
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes plastic band, electronic components, 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.
Plastic band degradation and microplastic shedding
Long-term UV exposure and sweat chemistry can cause elastomer bands to crack or degrade. While no recalls cite this for the PS-100, it is a general risk for plastic wearable bands after several years of daily wear, especially in hot climates.
Bacterial and fungal growth on band
Fitness tracker bands are known to trap moisture and sweat, creating conditions for skin microbes. This is a hygiene concern rather than a chemical hazard, but regular cleaning significantly reduces risk of skin irritation or infection.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
The PS-100 housing is sealed, and no recalls or test results document leaching of heavy metals from internal circuitry. General electronics safety standards (RoHS) limit lead and cadmium in mass-produced consumer devices, reducing likelihood of exposure during normal use.
Source, ATSDR ↗Adhesive or glue toxins in band attachment
No public information identifies the adhesive used to bond the band to the watch module. Most fitness tracker adhesives are low-VOC epoxy or polyurethane; no health complaints are on record for the PS-100 in this regard.
Formaldehyde / VOCs
Plastic fitness tracker bands typically use stable colorant additives that do not migrate to skin. No test data or complaints specific to the PS-100 suggest dye leaching or formaldehyde release from the band material.
Source, ATSDR ↗The full breakdown
What it's made of and why it matters
The PS-100 uses a plastic elastomer band (typical TPE or silicone rubber) paired with electronic components in a sealed plastic housing. Plastic bands in fitness trackers are chosen for flexibility and water resistance without requiring coatings that could degrade or shed microplastics. The sealed electronic module minimizes contact between skin and internal components, reducing leaching pathways compared to open-design wearables.
The brand's record and disclosure
Epson has not published material safety disclosures or PFAS statements for the PS-100. The brand's general approach to wearables has not generated public safety complaints or recalls tied to chemical hazards in available records. No certifications specific to material safety (e.g., Oeko-Tex, RoHS) are advertised for this model, though it meets basic regulatory compliance for consumer electronics in major markets.
How it compares in its category
The PS-100 is a mid-range fitness tracker from the early 2010s; it predates modern wearables with textile-heavy straps (which pose formaldehyde/dye risks) and does not rely on gel or liquid-filled sensors that could leach. Compared to contemporary alternatives, its simple plastic-band design carries lower chemical complexity. Newer Epson wearables have not significantly changed material strategy, suggesting acceptable long-term safety profile for this generation.
If you buy it
Rinse the band regularly with mild soap and water to remove sweat and bacteria buildup, which can irritate skin over time rather than from chemical leaching. Avoid prolonged exposure to direct heat or sunlight, which can degrade plastic over years. Replace the band if cracks, discoloration, or visible deterioration appears, as this may release small polymer fragments. Store in a cool, dry place when not in use to extend material lifespan.
