67mm Clip-on CPL Lens Filter Kit for Phone Camera
Coating formula unclear and may contain PFAS. Pass for now.
This clip-on camera filter's optical coatings are a mystery. Teflon-family coating sometimes appear in such coatings, and the brand stays silent on PFAS.

What 67mm Clip-on CPL Lens Filter Phone Camera is made of, ingredients and materials
This clip-on CPL (circular polarizing) filter consists of optical glass mounted in a metal frame (likely aluminum or brass). The critical unknown is the optical coating applied to the glass surfaces, anti-reflective and polarizing coatings often contain fluorinated compounds or other proprietary formulations that manufacturers rarely disclose. Glass itself is inert, but coatings are where chemical risk concentrates in optical products.
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.
Unspecified optical coating composition
Anti-reflective and polarizing coatings on glass lenses commonly use fluorinated or silicone-based formulations, but the brand does not disclose specifics for this filter. Risk is primarily inhalation during manufacturing or potential leaching if coating degrades; consumer exposure during normal use is low unless filter is ingested or heavily worn.
Coating degradation and particulate release
Over years of use, optical coatings can flake or separate from substrate glass, especially if exposed to moisture, heat, or mechanical stress. Degraded coatings may release fine particles; inhalation risk is minimal in normal phone camera use but present if filter is disassembled or abraded.
Metal frame leaching (aluminum or brass)
If the frame is bare aluminum, prolonged contact with skin oils or moisture can promote surface corrosion and trace metal release. Brass frames may contain lead (though unlikely in regulated markets). Contact is typically minimal and indirect in this application, but prolonged skin contact should be avoided.
Glass integrity and cutting risk
Dropped or damaged filters may shatter, creating sharp glass fragments. This is a mechanical hazard rather than chemical, but relevant for careful handling and storage, particularly in homes with children.
What’s reassuring
Bacterial growth in clip mechanism
No documented cases, but the clip housing may trap moisture and dust if not cleaned regularly. Risk is negligible for this specific product design.

The brand's record and disclosure
The brand has not publicly disclosed manufacturing details, material sourcing, or coating chemistry for this accessory line. The company's broader consumer electronics division has faced scrutiny over supply chain transparency but has not issued specific statements on optical filter safety. No independent certifications (RoHS, reach compliance statements) are documented for this specific product model.
How it compares in its category
Clip-on camera filters occupy a narrow, lightly regulated niche, optical coatings are rarely subject to the same disclosure requirements as food contact or textile products. Most competing brands (Neewer, K&F Concept, Hoya) similarly do not publicly specify coating composition. This product's risk profile is representative of the category, meaning the problem is structural opacity, not the brand-specific failure.
If you buy it
Store the filter in a dry case to prevent moisture ingress into coating layers, which can degrade optical performance and potentially release coating materials. Clean only with microfiber cloths; avoid solvents or prolonged contact with skin oils. Do not expose to prolonged heat or direct sunlight storage, as thermal stress may compromise coating adhesion. Inspect annually for hazing, scratches, or discoloration, these signal coating degradation and warrant replacement.
