Hoya HOYA HD Antistatic UV Filter
Lower concern; optical glass is inherently PFAS-free, but coatings unspecified.
Hoya HD UV filters are primarily optical glass, which contains no PFAS. Antistatic and filter coatings composition is not publicly disclosed, creating minor uncertainty about surface treatments.

The full breakdown
What it's made of and why it matters
This is a camera lens filter made from optical-grade glass with two functional coatings: an antistatic layer (likely silica-based) to repel dust and fingerprints, and a UV absorption layer to block ultraviolet light. Optical glass itself is chemically inert and poses no leaching risk. The coatings are applied in microscopic quantities and remain fixed to the glass surface during normal handling and cleaning.
The brand's record and disclosure
Hoya is a major Japanese optical manufacturer with decades of industry presence but provides no public material safety data sheets or chemical disclosure for consumer filter products. The company has not faced significant product safety recalls in the photography filter market. Transparency on coating composition and manufacturing is minimal, which is typical for optical coatings but limits independent verification.
How it compares in its category
Optical filters across all major brands (Canon, Nikon, Zeiss, B+W) use similar glass-substrate-plus-coating designs with minimal disclosed differences. Hoya filters are competitively positioned and do not carry known hazard flags relative to competitors. The antistatic feature is a practical upgrade over uncoated glass but does not introduce chemical hazards beyond standard UV filter designs.
If you buy it
Clean with lens-specific microfiber cloths and approved lens cleaning solutions; avoid abrasive materials that could damage coatings. The filter requires no special storage beyond dry conditions and protection from impact. Normal photography use (no heat exposure, no contact with skin or food) carries no identified risks. Replace if surface is visibly scratched or coating flakes, though this is rare under standard handling.
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 leachability or degradation
Antistatic and UV coatings are applied at microgram levels and chemically bonded to glass. No mechanism for release into food, water, or skin during normal optical use; coatings are exterior-facing only and do not contact user directly.
Heavy metals in optical coatings
Some UV and antistatic coatings may include trace metals (e.g., titanium, cerium, or rare earths) but composition is proprietary and unconfirmed for Hoya products. No evidence of migration or health impact in normal camera use; concern is theoretical only.
Volatile organic compound (VOC) off-gassing
Optical coatings are cured during manufacturing and do not off-gas during storage or use. The product is fully stabilized before sale and poses no inhalation risk.
Glass fragmentation hazard
If dropped or struck, the filter may shatter, creating sharp glass fragments. This is a physical safety concern unrelated to chemistry but relevant to product handling, especially in equipment-intensive environments.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
