Haida Greystone Multicoated UV Filter
Coating details missing and PFAS risk unconfirmed.
This UV filter's multicoat isn't publicly detailed. Some multicoat optics use fluorinated compounds, but the brand gives no answers.

What Haida Greystone Multicoated UV Filter is made of, ingredients and materials
This is optical-grade glass with a multilayer anti-reflective and UV-blocking coating applied to the surface. The base glass itself (silica-based) is not a material linked to PFAS; the risk sits entirely in the coating layers, which Samsung does not publicly specify. Typical multicoatings for UV filters use metal oxides (titanium dioxide, silicon dioxide, aluminum oxide) or proprietary polymers, but without ingredient disclosure, the exact composition and any fluorinated compounds remain unknown.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
Unknown / proprietary coating
A coating is recorded with no disclosed chemistry.
Coating delamination and wear
Multilayer optical coatings can separate or flake at edges or with repeated cleaning, potentially generating microscopic particles. No specific failure data exists for this Samsung model, but optical glass coatings are known to degrade after 5-10 years of use depending on storage and handling.
Heavy metals
Metal oxide multicoatings may incorporate trace metals (titanium, aluminum, or rare earths) or metal-based adhesion promoters. Since composition is undisclosed, the presence and bioavailability of any heavy metals cannot be ruled out; however, the coating is sealed and not in contact with food or skin during normal use.
Source, FDA ↗PFAS
Some premium optical coatings use Teflon-family coating binders to improve water and oil repellence. Samsung's silence on coating ingredients leaves this unresolved; industry use of Teflon-type coating-based primers on high-end filters is documented but not confirmed for this model.
Source, ATSDR ↗Biofilm or fungal growth on lens surface
Humid storage or condensation can allow algae or mold to colonize the coating surface, particularly if the filter is left damp. This is a cleanliness issue rather than a chemical toxicity hazard, but compromises function and may require aggressive cleaning.
What’s reassuring
Off-gassing or volatile organic compound release
Optical glass and cured coating systems do not typically release volatile organics after manufacturing. No reports of odor, fume, or respiratory symptoms from UV filter use exist in public records.
How is this PFAS grade calculated?
The brand's record and disclosure
Samsung has not published ingredient lists, material safety data sheets, or PFAS-avoidance commitments for this optical component. The company's broader camera and electronics divisions have faced environmental scrutiny but have not faced specific recalls tied to lens coatings. Absence of transparency on coating chemistry is the core concern; this is not a widely used consumer-facing product, so public testing and third-party certification data are minimal.
How it compares in its category
Optical filters and coatings are rarely subject to consumer safety testing, unlike cookware or textiles. Most UV filter manufacturers (Canon, Nikon, Zeiss, Hoya) similarly withhold detailed coating formulations as proprietary. This product is neither ahead of nor behind industry norms for transparency; the entire category operates with minimal public disclosure. For photography enthusiasts, reputation-based brand choice is the main differentiator rather than published safety data.
If you buy it
Handle the filter by the barrel or frame edge, never touch the coated surfaces, as skin oils and dust degrade the coating and reduce UV blocking efficiency over time. Store in a dry, cool place away from direct sunlight and extreme temperature swings, as thermal stress can cause coating delamination. Clean only with lens-grade microfiber cloths and appropriate optical cleaning solution; harsh solvents may interact with the coating binder. Replace if you notice visible scratches, clouding, or reflective discoloration, as the protective layers have failed.
