B+W 67mm UV Haze Filter
Lower concern. Optical glass and standard coatings unlikely to contain PFAS.
B+W UV filters use optical glass with anti-reflective multi-coatings. No PFAS disclosure exists, but glass optics and typical lens coatings present lower PFAS risk than textiles or cookware.

The full breakdown
What it's made of and why it matters
B+W UV Haze filters use optical-grade borosilicate or soda-lime glass as the substrate, chosen for optical clarity and UV transmission properties. The multi-coated lens surfaces are typically hard-coated with metal oxides (titanium dioxide, silicon dioxide, magnesium fluoride) to reduce reflection and improve light transmission. These inorganic coatings are stable, non-leaching, and do not off-gas under normal photographic use. The filter is not heated, ingested, or worn against skin, eliminating typical exposure routes for coatings.
The brand's record and disclosure
B+W (Schneider Optics) maintains a professional reputation in precision optics with no public safety controversies or recalls affecting this filter line in consumer records. The company does not prominently disclose PFAS avoidance or materials testing, consistent with the optical optics industry norm of minimal transparency on coating chemistry. No third-party certifications (e.g., RoHS, CE) are routinely promoted for this product, though it meets generic EU safety standards for optical devices.
How it compares in its category
UV filters are among the lowest-risk photographic accessories; they contain no plastics, adhesives, or volatile off-gassing components that affect image capture gear. Competing brands (Hoya, Kenko, Canon) use comparable borosilicate glass and oxide coatings with similar safety profiles. The main differentiation is optical performance (coating quality) rather than material safety, making B+W a mainstream, safe choice in this segment.
If you buy it
Store the filter in its protective case or pouch to avoid scratches and dust accumulation on coatings; do not clean with harsh solvents or abrasives, which can degrade the multi-coat layer. Clean gently with a soft brush, microfiber cloth, and lens fluid if needed. No heat exposure or outdoor weathering occurs in typical camera use, so the filter is effectively maintenance-free. Replace only if coatings are visibly damaged (cracks, haze, flaking), which is rare.
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 surfaces can degrade over decades of intense UV exposure or if exposed to prolonged moisture and salt air (marine environments), potentially reducing optical performance but not releasing hazardous particles into the environment.
Heavy metals in glass or coatings
Optical-grade borosilicate glass and standard metal-oxide coatings do not contain lead, cadmium, or other regulated heavy metals in formulations used by B+W; no recalls or test alerts on record.
Volatile organic compound (VOC) or off-gassing
Glass and inorganic oxide coatings do not off-gas solvents or formaldehyde; this product poses no chemical inhalation risk even in enclosed camera bags or storage.
Leaching from adhesives or cements
B+W filters use minimal bonding; the glass and coatings are mechanically stable and not cemented in ways that would leach into food, water, or skin contact surfaces.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
