Freewell ND Filter 4-Pack for Samsung Galaxy Ultra
Lower PFAS concern; optical glass filters lack typical PFAS triggers.
ND filters are primarily optical glass with aluminum housings. No Teflon-family coating coatings or water-repellent treatments typical of PFAS exposure. Brand silent on PFAS but material composition suggests lower risk.

The full breakdown
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.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
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.
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 in optical coatings
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.
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 we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
