Tiffen Series 9 Clear Standard Coated Filter S9CLR
Optical glass filters carry minimal PFAS risk. No specific brand disclosure available.
Camera filters typically use glass with multi-coatings for anti-reflectance and durability. Tiffen does not disclose PFAS content, but optical coatings rarely require PFAS chemistry.

What Tiffen Series 9 Clear Filter S9CLR is made of, ingredients and materials
The Tiffen Series 9 Clear Standard Coated Filter consists of optical-grade borosilicate or soda-lime glass with a factory-applied multi-layer anti-reflection or protective coating designed to minimize reflections and protect the lens. The coating is typically composed of metal oxides (magnesium fluoride, titanium dioxide, or similar compounds) fused to the glass surface at high temperature. Unlike food-contact cookware or textiles, this product does not contact skin, food, or mouth, and is used only for light transmission in cameras, eliminating typical dermal or ingestion exposure pathways.
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.
Unknown / proprietary coating
A coating is recorded with no disclosed chemistry.
Optical coating delamination or scratching
Over extended use or if dropped, the fused coating may crack or peel, potentially shedding microscopic particles into the camera mechanism. This is a mechanical rather than chemical hazard and does not affect the user directly.
Fragmentation hazard if dropped
Like all glass optics, the filter can shatter if subjected to significant impact. Broken glass shards pose a minor cutting hazard during handling and cleanup, but this is incidental to the material chemistry and not specific to Tiffen's product.
What’s reassuring
No identified leaching or chemical release
Borosilicate glass and fused metal-oxide coatings are chemically inert under normal conditions. No established risk of heavy metals, organic compounds, or other toxins leaching from the filter into camera sensors or the user's hands.
How is this PFAS grade calculated?
The brand's record and disclosure
Tiffen is a long-established optics manufacturer with no public history of chemical disclosure statements regarding PFAS or hazardous coatings in their filters. The company does not advertise certifications for optical safety beyond standard photographic industry specifications (ISO optical standards). No recalls or chemical controversies specific to this filter line are on record in consumer safety databases or photographic industry forums.
How it compares in its category
Clear protective filters are among lower concern optical products because they impose no heating or mechanical stress on coatings and see minimal environmental degradation. Tiffen's standard coated filters sit in the mid-range of the market; premium competitors (such as B+W or Hoya) often emphasize multi-coated designs but do not disclose fundamentally lower concern chemistry. Budget or uncoated alternatives carry equivalent or slightly higher risk of coating delamination over time, which can introduce microscopic glass particles into cameras rather than the optical path.
If you buy it
Store the filter in a protective case to prevent scratching or impact that could degrade the coating. Clean only with lens-grade microfiber cloths and optical cleaning solution designed for coated glass; avoid harsh solvents or abrasive papers. The coating is permanent and fused to the glass, so normal photography use poses no shedding or leaching risk. Replace only if the coating visibly delaminates, cracks, or develops haze that affects image quality, which typically requires years of heavy use or storage in extreme humidity.
