Freewell ND Filter 4-Pack for Samsung Galaxy Ultra
Reduced PFAS concern; optical glass filters lack typical PFAS triggers.
Freewell ND filters are primarily optical glass with aluminum housings, materials without Teflon-family coating coatings or water-repellent treatments typical of PFAS exposure. Material composition suggests lower risk.

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.
Optical coating degradation
Multi-coated optical glass filters may have anti-reflection layers (typically magnesium fluoride or similar compounds). Prolonged exposure to humidity, salt spray, or scratching can degrade coatings over years, but this affects optical performance, not safety.
Adhesive or bonding agents
Glass-to-frame bonding may use optical cements or epoxy adhesives. These are not in direct contact with skin or consumables and do not off-gas significantly in a dry camera accessory. No specific data on Freewell's adhesive chemistry is publicly available.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Aluminum frame corrosion and leaching
Anodized aluminum frames are designed to prevent direct contact between aluminum and skin or lenses. No established risk of aluminum migration into food, water, or body contact from camera filter frames in normal use.
Microplastic or particulate shedding
Optical glass and anodized aluminum do not shed microplastics. The frame seal and glass are inert and stable over the product lifespan.
Heavy metals
Standard optical glass coatings (fluoride, oxide, or rare-earth compounds) do not contain lead, cadmium, or other regulated heavy metals in formulations meeting international optical standards. No established contamination in this product category.

What it's made of and why it matters
Freewell ND filters are composed of optical-grade glass (typically borosilicate or similar low-expansion glass) bonded to an aluminum alloy frame. Optical glass is chemically inert and does not leach into food, water, or skin contact. The aluminum frame is anodized or powder-coated to prevent corrosion and metal migration, making it stable under normal use conditions as a camera lens accessory.
The brand's record and disclosure
Freewell is a smaller third-party camera accessory manufacturer; Samsung markets but does not manufacture these filters. Neither company has published detailed material safety datasheets or sustainability disclosures specific to this product line. No recalls or safety complaints are documented for Freewell ND filters. Brand transparency on chemical composition is minimal, typical of the camera accessory category.
How it compares in its category
Camera lens filters across brands (Freewell, B+W, Tiffen, Hoya) rely on similar optical glass and aluminum construction. This product sits in the mid-range for accessories and carries no known safety disadvantages versus premium alternatives. The primary differentiation is optical quality and durability, not chemical hazard profile.
If you buy it
Store filters in a dry case to prevent dust accumulation and aluminum frame corrosion. Avoid dropping or applying pressure to the glass, as cracks expose the internal optical coating. Clean only with microfiber cloth and lens cleaner; abrasive materials can degrade anti-reflection coatings. No special handling or replacement intervals are needed beyond normal wear.
