B&W B+W UV-Filter F-Pro 010 MRC 77
Optical glass filter. No PFAS disclosure found. Lower concern likely.
UV filters are optical glass with anti-reflective coatings. B+W does not publicly disclose PFAS content. Glass substrate itself is inherently PFAS-free, but coating composition remains unspecified.

The full breakdown
What it's made of and why it matters
The B+W F-Pro 010 is a UV absorption filter made from optical glass with multi-coated (MRC) anti-reflection lens coatings. The glass itself is chemically inert and does not leach or off-gas during normal use. The MRC coating is a thin multilayer stack of metal oxides (typically magnesium fluoride, aluminum oxide, or similar) designed to reduce reflections and improve light transmission; these materials are standard in optics and not known to degrade into hazardous byproducts under normal handling or light exposure.
The brand's record and disclosure
B+W (Schneider Optics) has not published explicit PFAS-free certifications for optical filters, but the product category (glass optics) is not flagged in major PFAS disclosure campaigns. The brand is an established German optics manufacturer with no public safety recalls or health controversies related to optical filters. Disclosure is minimal, which is typical for optics; the lack of transparency is not an indicator of hidden risk in this case.
How it compares in its category
Optical glass filters are inherently low-risk compared to coated cookware or chemical-laden cosmetics. UV filters of this type are a commodity; Hoya, Kenko, and other competitors use similar optical glass and oxide coatings. The MRC coating in this model is standard professional-grade optics technology with no meaningful differentiation in safety profile between brands in this segment.
If you buy it
Store the filter in a clean, dry case to prevent dust and fingerprints. Do not expose it to extreme temperature swings or solvents; lens cleaning fluid and soft cloths are appropriate. The glass and coating are durable indefinitely under normal photographic use. No maintenance beyond occasional cleaning is required; replacement is not necessary unless optical degradation becomes visible (rare without physical damage).
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.”
Coating delamination or degradation
Multi-coated optical filters can theoretically degrade if exposed to extreme humidity, temperature cycling, or harsh solvents, but this is not established as a problem for B+W MRC filters under normal use. Damage would be optical (loss of coating function) rather than a health hazard.
Heavy metals in optical coatings
Oxide-based MRC coatings do not contain cadmium, lead, or other regulated heavy metals. Professional optics manufacturing is not associated with toxic metal contamination in this product class.
Leaching or off-gassing from glass or coatings
Optical glass is chemically stable and does not leach contaminants into food, water, or skin. Metal oxide coatings are similarly inert and do not off-gas volatile compounds during normal light exposure or handling.
Manufacturing residues on coating surface
New optical filters may have light dust, oils, or manufacturing residue on the glass surface, but these are external contaminants, not hazardous materials. Simple lens cleaning before first use resolves this.
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.
